Delivering strong earnings and cash flow performance in 

2010, Lennox International is firmly positioned for success  

in growth markets with significant pent-up demand. Without 

exception, our end markets returned to growth in 2010— 

and we expect growth to continue in 2011.

We’re ready to take advantage. We introduced a host of major new products and made outstanding progress in 

enhancing our distribution and manufacturing. We have also aggressively reduced our cost structure and are well 

positioned for continued significant margin expansion. While continuing to make transformational investments 

in  our  business,  we  also  are  making  strategic  acquisitions  in  our  core  businesses,  paying  a  competitive 

 dividend, and repurchasing stock—including $144 million in 2010 and $700 million over the last four years.

Total company revenue for 2010 was $3.1 billion, up 9% from the prior year, including a positive 2 point impact 

from  foreign  exchange.  Total  segment  profit  margin  was  up  120  basis  points  to  7.0%.  Diluted  earnings  per 

share from continuing operations on a GAAP basis was $2.10, up 93% from $1.09 in the prior year.

Cash  generated  from  operations  for  the  year  was  $186  million.  The  company  invested  $46  million  in  capital 

assets, resulting in free cash flow of $140 million. Total debt as of December 31, 2010 was $319 million. Total 

cash and cash equivalents were $160 million ending the year.

Driven by our employees and our values, we will make the most of market opportunities by continued focus on 

our strategic priorities:

innovative product systems and solutions: We introduced a host of new products that won customer accolades 

and  industry  awards  in  2010,  including  four  Dealer  Design  awards  from  leading  industry  publication  ACHR 

News—the most of any manufacturer. These products are also winning in the market with sales: 35% of our 

Lennox International Inc.
2010 Annual Report

revenue  in  2010  came  from  products  introduced  in  the  past  three  years,  up  10  percentage  points  from  two 

years ago.

Expanding on our innovative solutions in refrigeration, we signed an agreement with The Manitowoc Company, 

Inc. in December to acquire substantially all the assets of its Kysor/Warren business. The $145 million acquisition 

was closed in January 2011. Kysor/Warren is a leading manufacturer of refrigerated systems and display cases 

for North American supermarkets. Our refrigeration subsystems, combined with Kysor/Warren’s  systems  

and  display  cases,  will  provide  complete  solutions  using  the  most  advanced  technologies  to  maximize  

energy efficiency.

manufacturing and sourcing excellence: We continued ramping up our 300,000-plus sq. ft. Saltillo, Mexico 

facility in 2010 and are on track to achieve an annual $20 million in savings exiting 2011. Our global sourcing 

strategy  continues  to  provide  significant  savings,  with  our  spending  outside  North  America  increasing  from 

15% to 40% over the past few years. We saved approximately $30 million in 2010 on top of $20 million in savings 

in 2009. We expect to achieve an incremental $30 million of savings in 2011.

Distribution  excellence:  Major  progress  continued  on  doubling  our  physical  distribution  locations  in  North 

America through a new regional distribution network. Six of eight planned regional distribution centers are in 

place, with all eight expected by the end of 2011. Sixty-two PartsPlus™ storefronts were in place by the end of 

2010, with a total of 100 planned by the end of 2011 and 133 by the end of 2012. We expect a $25 million pre-tax 

benefit from this initiative in 2013.

geographic  expansion:  Our  business  outside  North  America  improved  from  roughly  breakeven  in  2009  to 

a  4%  operating  margin  in  2010.  After  realigning  organizations  and  distribution,  as  well  as  restructuring  our 

factories, we are confident this business is well positioned for growth and profitability.

Expense reduction: We have lowered our cost structure by $58 million over the last 4 years through restructuring 

actions  around  the  world,  and  we  expect  additional  savings  in  2011.  As  markets  continue  to  grow,  we  will 

 benefit from leverage on our factory fixed cost, with room for significant growth in the coming years without adding 

 factories. We will benefit from leverage on selling, general, and administrative expenses (SG&A) as we plan for 

these  expenses  to  grow  at  half  the  rate  of  revenue  growth  on  a  long-term  basis.  And  we  are  increasingly 

focused  on  other  opportunities  for  productivity  improvement  with  product  platform  cost  reductions  and 

enhanced freight and logistics operations.

After  several  challenging  years  for  our  industry,  our  end  markets  are  expected  to  continue  the  growth  they 

began in 2010. Thanks to our strong focus on reducing costs, making transformative investments, developing 

innovative products and enhancing our manufacturing and distribution, Lennox International is well positioned 

to take advantage of recovering markets and continue to build shareholder value.

the  residential  market  is  expected  to  continue  its  recovery  in  2011,  and  lii  residential  is 
ready  to  capitalize  on  our  investments  in  innovative  products.  We  successfully  introduced  
a  host  of  exciting  new  products  that  are  winning  industry  awards,  growing  sales  in  the

Featuring  a  compact  33-inch  design  for  use  in  a  wide  variety  of  applications,  our  new  gas 
furnace platform is a winner with dealers and homeowners. precise comfort™ technology 
automatically adjusts heat and airflow in increments as small as 1% with an industry-leading

tying the system together, the icomfort touch® programmable thermostat uses an intuitive 
touchscreen interface to make installation and comfort adjustments quick and easy. Winner 
of an ACHR News Dealer Design award in 2010, the simplicity of the icomfort touch makes 
it  easier  for  homeowners  to  customize  their  indoor  environments  and  provide  more

continuing  to  support  these  new  products  through  an  enhanced  distribution  strategy,  we 
are  well  on  our  way  to  completing  a  multi-year  initiative  to  more  than  double  our  physical 
distribution locations across north america. Six of our eight planned regional distribution 
centers  are  in  place,  with  all  eight  expected  to  be  in  operation  by  the  end  of  2011.  our 
partsplus wholesale store initiative grew to 62 stores by the end of 2010, with 100 expected 
by the end of 2011 and 133 stores planned to be in place by the end of 2012. We expect our 
new  distribution  network  to  increase  our  same-day/next-day  service  levels  to  85%,  drive 
improvements  in  logistics  productivity  and  cost  savings,  and  increase  market  share  in  an 
industry where physical distribution drives market gains.

Led by successful launches of our SunSource® 
Home Energy System, icomfort Touch® 
thermostat and compact gas furnace  
platform, our new products are winning 
industry awards and growing sales in the 
marketplace.

our  refrigeration  business  continues  to  excel  in  providing  sustainable  innovative   system 
solutions  to  our  customers  around  the  world.  We  have  expanded  the  use  of  microchannel 
heat exchanger technology throughout our north american, European, asian, and australian 
businesses. our innovative ½-6 horsepower air-cooled condensing unit  solutions have been 
honored  by  various  customers  and  influential  industry  publications,  including  a  Silver 
Dealer  Design  award  from  ACHR  News.  We  continue  to  expand  this  technology  into  new 
applications, including large remote condensers with reduced refrigerant of up to 70% and 
increased energy performance for supermarket refrigeration systems.

another example of our global sustainable product development is the launch of co2 systems 
in our north american, European, and australian businesses, utilizing a natural refrigerant 
to  help  our  supermarket  customers  reduce  their  global  warming  impact  by  more  than  
50%.  We  continue  to  work  with  our  customers  to  develop  the  optimal  life  cycle  climate 
 performance of their refrigeration systems.

We  continue  to  invest  in  operational  excellence  initiatives  across  our  global  operations 
focused  on  improving  employee  safety,  as  well  as  improving  productivity  and  quality 
 performance  for  our  customers.  as  part  of  these  initiatives,  we  further  streamlined  our 
 manufacturing operations by closing our parets, Spain, and milperra, australia operations, 
while continuing to make investments in our china business.

in December 2010, we signed an agreement to acquire substantially all the assets of Kysor/
Warren,  a  leading  manufacturer  of  refrigerated  systems  and  display  cases  for  north 
american  supermarkets,  and  completed  the  transaction  in  January  2011.  By  combining 
Kysor/Warren’s  innovation  and  service  with  our  industry-leading  refrigeration  subsystems, 
we can now provide a complete refrigeration solution using the most advanced technologies 
that  maximize  energy  efficiency,  environmental  sustainability,  and  economic  value  to 
 supermarket customers.

Through our acquisition of Kysor/Warren and 
launches of new products utilizing innovative 
microchannel and CO2 technologies, we can 
provide complete refrigeration solutions 
 optimizing energy efficiency, environmental 
sustainability, and economic value.

We were founded in 1895 in Marshalltown, Iowa when Dave Lennox, the owner of a machine repair business
for the railroads, successfully developed and patented a riveted steel coal-fired furnace, which was substantially
more durable than the cast iron furnaces used at that time. Manufacturing these furnaces grew into a significant
business and was diverting the Lennox Machine Shop from its core focus. As a result, in 1904, a group of investors
headed by D.W. Norris bought the furnace business and named it the Lennox Furnace Company. We reincorporated
as a Delaware corporation in 1991 and completed our initial public offering in 1999.

Products and Services

Residential Heating & Cooling

Heating & Cooling Products. We manufacture and market a broad range of furnaces, air conditioners, heat
pumps, packaged heating and cooling systems, accessories to improve indoor air quality, replacement parts and
related products for both the residential replacement and new construction markets in North America. These
products are available in a variety of designs and efficiency levels and at a range of price points, and are intended to
provide a complete line of home comfort systems. We believe that by maintaining a broad product line marketed
under multiple brand names, we can address different market segments and penetrate multiple distribution
channels. We are building a network of PartsPlus stores across the United States that provide an easy access
solution for contractors and independent dealers to obtain universal service and replacement parts, supplies,
convenience items, tools, Lennox equipment and OEM parts.

The “Lennox” and “Aire-Flo” brands are sold directly to a network of approximately 7,000 independent
installing dealers, making us one of the largest wholesale distributors of residential heating and air conditioning
products in North America. The “Armstrong Air,” “Ducane,” “AirEase,” “Concord,” “Magic-Pak” and “Advanced
Distributor Products” brands are sold through independent distributors.

Our Advanced Distributor Products operation builds evaporator coils and air handlers under the “Advanced
Distributor Products” brand, as well as the “Lennox,” “Armstrong Air,” “AirEase,” “Concord” and “Ducane”
brands. In addition to supplying us with components for our heating and cooling systems, Advanced Distributor
Products also sells evaporator coils to our competitors for use in their heating and cooling products.

Hearth Products. Our hearth products include factory-built gas, wood-burning and electric fireplaces; free
standing wood-burning, pellet and gas stoves; wood-burning, pellet and gas fireplace inserts; gas logs, venting
products and accessories. Many of our fireplaces are built with a blower or fan option and are efficient heat sources
as well as attractive amenities to the home. We currently market our hearth products under the “Lennox,”
“Superior,” “Country Collection” and “Security Chimneys” brand names.

Commercial Heating & Cooling

North America.

In North America, we manufacture and sell unitary heating and cooling equipment used in
light commercial applications, such as low-rise office buildings, restaurants, retail centers, churches and schools.
Our product offerings for these applications include rooftop units ranging from 2 to 50 tons of cooling capacity and
split system/air handler combinations, which range from 1.5 to 20 tons of cooling capacity. These products are
distributed primarily through commercial contractors and directly to national account customers. We believe the
success of our products is attributable to their efficiency, design flexibility, total cost of ownership, low life-cycle
cost, ease of service and advanced control technology.

Europe.

In Europe, we manufacture and sell unitary products, which range from 2 to 70 tons of cooling
capacity, and applied systems with up to 200 tons of cooling capacity. Our European products consist of small
package units, rooftop units, chillers, air handlers and fan coils that serve medium-rise commercial buildings,
shopping malls, other retail and entertainment buildings, institutional applications and other field-engineered
applications. We manufacture heating and cooling products in several locations in Europe and market these
products through both direct and indirect distribution channels in Europe, Russia, Turkey and the Middle East.

Service Experts

Approximately 100 company-owned Service Experts dealer service centers provide installation, preventive
maintenance, emergency repair and replacement of heating and cooling systems directly to residential and light
commercial customers throughout the U.S. and Canada. In connection with these services, we sell a wide range of
our manufactured equipment, parts and supplies, and third-party branded products. We focus primarily on service
and replacement opportunities, which we believe are more stable and profitable than new construction in our
Service Experts segment. We also have a growing Lennox National Account Services business that focuses on
providing service and preventive maintenance to commercial national account customers. We use a portfolio of
management procedures and best practices, including standards of excellence for customer service, common

2

information technology systems and financial controls, a national accounting center and an inventory management
program designed to enhance the quality, effectiveness and profitability of operations.

Refrigeration

We manufacture and market equipment for the global commercial refrigeration market under the Heatcraft
Worldwide Refrigeration name. We sell these products to distributors, installing contractors, engineering design
firms, original equipment manufacturers and end-users.

North America. Our commercial refrigeration products for the North American market include condensing
units, unit coolers, fluid coolers, air-cooled condensers, compressor racks and air handlers. These products are sold
for refrigeration applications, primarily to preserve food and other perishables, and are used by supermarkets,
convenience stores, restaurants, refrigerated warehouses and distribution centers. As part of the sale of commercial
refrigeration products, we routinely provide application engineering for consulting engineers, contractors and
others. We also sell products for non-food and various industry applications, such as telecommunications,
dehumidification and medical applications. In January 2011 we completed a transaction with The Manitowoc
Company, Inc. by which we acquired substantially all the assets of its Kysor/Warren business. Kysor/Warren is a
leading manufacturer of refrigerated systems and display cases for supermarkets throughout North America. This
acquisition provides us with a platform for additional business growth by extending the value chain for us directly to
food retail and supermarket customers.

International.

In international markets, we manufacture and market refrigeration products including con-
densing units, unit coolers, air-cooled condensers, fluid coolers, compressor racks and process chillers. We have
manufacturing locations in Germany, France, Australia, New Zealand, Brazil and China. We also own a 50%
common stock interest in a joint venture in Mexico that produces unit coolers, air-cooled condensers, condensing
units and compressor racks of the same design and quality as those manufactured by our U.S. business. This joint
venture product line is complemented with imports from the U.S., which are sold through the joint venture’s
distribution network. We also own an 8% common stock interest in a manufacturer in Thailand that produces
compressors for use in our products and for other HVACR customers.

Business Strategy

Our business strategy is to sustain and expand our premium market position through organic growth and
acquisitions while maintaining our focus on cost reductions to drive margin expansion and support growth in target
business segments. This strategy is supported by five strategic priorities that are underlined by our values and our
people. The five strategic priorities are:

Innovative Product and System Solutions

In all of our markets, we are continually building on our heritage of innovation by developing residential,
commercial, and refrigeration products that give families and business owners more precise control over more
aspects of their indoor environments, while significantly lowering their energy costs.

Manufacturing and Sourcing Excellence

We maintain our commitment to manufacturing and sourcing excellence by driving low-cost assembly through
rationalization of our facilities and product lines, maximizing factory efficiencies, and leveraging our purchasing
power and sourcing initiatives to expand the use of lower-cost components that meet our high-quality requirements.

Distribution Excellence

By investing resources in expanding our distribution network, we are making products available to our
customers in a timely, cost-efficient manner. Additionally, we provide enhanced dealer support through the use of
technology, training, advertising and merchandising.

3

Geographic Expansion

We are growing our international presence by continuing to extend our successful domestic business model

and product knowledge into international markets.

Expense Reduction

Through our cost management initiatives, we are focused on areas to reduce operating, manufacturing, and

administrative costs.

Marketing and Distribution

We utilize multiple channels of distribution and offer different brands at various price points in order to better
penetrate the HVACR markets. Our products and services are sold through a combination of distributors,
independent and company-owned dealer service centers, other installing contractors, wholesalers, manufacturers’
representatives and original equipment manufacturers and to national accounts. Dedicated sales forces and
manufacturers’ representatives are deployed across our business segments and brands in a manner designed to
maximize our ability to service a particular distribution channel. To optimize enterprise-wide effectiveness, we have
active cross-functional and cross-organizational teams coordinating approaches to pricing, product design, dis-
tribution and national account customers.

An example of the competitive strength of our marketing and distribution strategy is in the North American
residential heating and cooling market. We use three distinctly different distribution approaches in this market: the
company-owned distribution system, the independent distribution system and sales made directly to end-users. We
distribute our “Lennox” and “Aire-Flo” brands in a company-owned process directly to independent dealers that
install these heating and cooling products and, in some cases, we sell “Lennox” commercial products directly to
national account customers. We distribute our “Armstrong Air,” “Ducane,” “AirEase,” “Concord,” “Magic-Pak” and
“Advanced Distributor Products” brands through the traditional independent distribution process pursuant to which
we sell our products to distributors who, in turn, sell the products to installing contractors. In addition, we provide
heating and cooling replacement products and services directly to consumers through company-owned Service
Experts dealer service centers.

Over the years, the “Lennox” brand has become synonymous with “Dave Lennox,” a highly recognizable
advertising icon in the heating and cooling industry. We utilize the “Dave Lennox” image in mass media
advertising, as well as in numerous locally produced dealer advertisements, open houses and trade events.

Manufacturing

We operate manufacturing facilities in the U.S. and international locations. We have embraced lean-man-
ufacturing principles, a manufacturing philosophy that reduces waste in manufactured products by shortening the
timeline between the customer order and delivery, accompanied by initiatives designed to achieve high product
quality across our manufacturing operations. In our facilities most impacted by seasonal demand, we manufacture
both heating and cooling products to balance seasonal production demands and maintain a relatively stable labor
force. We are generally able to hire temporary employees to meet changes in demand.

Strategic Sourcing

We rely on various suppliers to furnish the raw materials and components used in the manufacturing of our
products. To maximize our buying effectiveness in the marketplace, our central strategic sourcing group consol-
idates required purchases of materials, components and indirect items across business segments. The goal of the
strategic sourcing group is to develop global strategies for a given component group, concentrate purchases with
three to five suppliers and develop long-term relationships with these vendors. By developing these strategies and
relationships, we leverage our material needs to reduce costs and improve financial and operating performance.
Compressors, motors and controls constitute our most significant component purchases, while steel, copper and
aluminum account for the bulk of our raw material purchases. We own equity interests in joint ventures that

4

manufacture compressors. These joint ventures provide us with compressors for our residential, commercial and
refrigeration businesses.

Our centrally led supplier development group works with selected suppliers to reduce their costs and improve
their quality and delivery performance. We seek to accomplish this by employing the same business excellence
tools utilized by our business segments to drive improvements in the area of lean manufacturing and six sigma, a
disciplined, data-driven approach and methodology for improving quality.

Research and Development and Technology

An important part of our growth strategy is continued investment in research and product development to both
develop new products and make improvements to existing product lines. As a result, we spent an aggregate of
$49.5 million, $48.9 million and $46.0 million on research and development during 2010, 2009 and 2008,
respectively. We operate a global engineering and technology organization that focuses on new technology
invention, product development, and process improvements.

Intellectual property and innovative designs are leveraged across our businesses. We leverage product
development cycle time improvement and product data management systems to commercialize new products
to market more rapidly. We use advanced, commercially available computer-aided design, computer-aided
manufacturing, computational fluid dynamics and other sophisticated design tools to streamline the design and
manufacturing processes. We use complex computer simulations and analyses in the conceptual design phase
before functional prototypes are created.

We also operate a full line of prototype machine equipment and advanced laboratories certified by applicable

industry associations.

Seasonal Nature of Business

Our sales and related segment profit tend to be seasonally higher in the second and third quarters of the year
because summer is the peak season for sales of air conditioning equipment and services in the U.S. and Canada.

Our markets are driven by seasonal weather patterns. HVAC products and services are sold year round, but the
volume and mix of product sales and service change significantly by season. The industry ships roughly twice as
many units during June as it does in December. Overall, cooling equipment represents a substantial portion of the
annual HVAC market. In between the heating season (roughly November through February) and cooling season
(roughly May through August) are periods commonly referred to as shoulder seasons when the distribution channel
transitions its buying patterns from one season to the next. These seasonal fluctuations in mix and volume drive our
sales and related segment profit, resulting in somewhat higher sales in the second and third quarters due to the larger
cooling season relative to the heating season.

Patents and Trademarks

We hold numerous patents that relate to the design and use of our products. We consider these patents
important, but no single patent is material to the overall conduct of our business. We proactively obtain patents to
further our strategic intellectual property objectives. We own or license several trademarks and service marks we
consider important in the marketing of our products and services, including LENNOX», ARMSTRONG AIR»,
DUCANETM, ALLIED COMMERCIALTM, AIRE-FLO», CONCORD», ADP ADVANCED DISTRIBUTOR
PRODUCTS», MAGIC-PAK», HUMIDITROLTM, PRODIGY», HEATCRAFT» WORLDWIDE REFRIGERA-
TION, BOHN», CHANDLER REFRIGERATION», KIRBYTM AND LARKIN», among others. We protect our
marks through national registrations and common law rights.

Competition

Substantially all markets in which we participate are highly competitive. The most significant competitive
factors we face are product reliability, product performance, service and price, with the relative importance of these
factors varying among our businesses. Listed below are some of the companies we view as significant competitors

(cid:129) Refrigeration — United Technologies Corp.

(Carrier); Ingersoll-Rand plc (Hussmann); Emerson Electric
Co. (Copeland); GEA Group (Kuba, Searle, Goedhart); and Alfa Laval (Alfa Laval, Fincoil, Helpman).

Employees

As of December 31, 2010, we employed approximately 11,800 employees, of whom approximately 4,800
were salaried and 7,000 were hourly. The number of hourly workers we employ may vary in order to match our
labor needs during periods of fluctuating demand. Approximately 2,400 employees are represented by unions. We
believe our relationships with our employees and with the unions representing our employees are good and
currently we do not anticipate any material adverse consequences resulting from negotiations to renew any
collective bargaining agreements.

Environmental Regulation

Our operations are subject to evolving and often increasingly stringent international, federal, state and local
laws and regulations concerning the environment. Environmental laws that affect or could affect our domestic
operations include, among others, the National Appliance Energy Conservation Act of 1987, as amended
(“NAECA”), the Energy Policy Act, the Clean Air Act, the Clean Water Act, the Resource Conservation and
Recovery Act, the Comprehensive Environmental Response, Compensation and Liability Act, the National
Environmental Policy Act, the Toxic Substances Control Act, any regulations promulgated under these acts
and various other international, federal, state and local laws and regulations governing environmental matters. We
believe we are in substantial compliance with such existing environmental laws and regulations.

Energy Efficiency. The U.S. Department of Energy is conducting rule makings to evaluate the current
minimum efficiency standards for residential heating and cooling products. On December 19, 2007, federal
legislation was enacted authorizing the U.S. Department of Energy to study the establishment of regional efficiency
standards for residential furnaces, air conditioners and heat pumps. We anticipate that the U.S. Department of
Energy will establish regional standards for furnaces and air conditioners as part of the rulemakings. We have
established a process that we believe will allow us to offer new products that meet or exceed these new standards in
advance of implementation. Similar new standards are being promulgated for commercial air conditioning and
refrigeration equipment. We are actively involved in U.S. Department of Energy and Congressional activities
related to energy efficiency standards. We are prepared to have compliant product in place in advance of the
implementation of all such regulations being considered by the U.S. Department of Energy or Congress.

Refrigerants. The use of hydrochlorofluorocarbons, “HCFCs,” and hydroflurocarbons “HFCs” as refriger-
ants for air conditioning and refrigeration equipment is common practice in the HVACR industry. We have
complied with applicable rules and regulations governing the use of HCFCs and HFCs. The United States Congress,
Environmental Protection Agency and other international regulatory bodies are considering steps to phase down the
future use of HFCs in HVACR products. We have been an active participant in the ongoing international and
domestic dialogue on this subject and believe we are well positioned to react in a timely manner to any changes in
the regulatory landscape. In addition, we are taking proactive steps to implement responsible use principles and

6

guidelines with respect to limiting refrigerants from escaping into the atmosphere throughout the life span of our
HVACR equipment.

Remediation Activity.

In addition to affecting our ongoing operations, applicable environmental laws can
impose obligations to remediate hazardous substances at our properties, at properties formerly owned or operated
by us and at facilities to which we have sent or send waste for treatment or disposal. We are aware of contamination
at some of our facilities; however, based on facts presently known, we do not believe that any future remediation
costs at such facilities will be material to our results of operations. For more information, see Note 10 in the Notes to
our Consolidated Financial Statements.

In the past, we have received notices that we are a potentially responsible party along with other potentially
responsible parties in Superfund proceedings under the Comprehensive Environmental Response, Compensation
and Liability Act for cleanup of hazardous substances at certain sites to which the potentially responsible parties are
alleged to have sent waste. Based on the facts presently known, we do not believe environmental cleanup costs
associated with any Superfund sites where we have received notice that we are a potentially responsible party will
be material.

European WEEE and RoHS Compliance.

In the European marketplace, electrical and electronic equipment
is required to comply with the Directive on Waste Electrical and Electronic Equipment (“WEEE”) and the Directive
on Restriction of Use of Certain Hazardous Substances (“RoHS”). WEEE aims to prevent waste by encouraging
reuse and recycling and RoHS restricts the use of six hazardous substances in electrical and electronic products. All
HVACR products and certain components of such products “put on the market” in the EU (whether or not
manufactured in the EU) are potentially subject to WEEE and RoHS. Because all HVACR manufacturers selling
within or from the EU are subject to the standards promulgated under WEEE and RoHS, we believe that neither
WEEE nor RoHS uniquely impact us as compared to such other manufacturers. Similar directives are being
introduced in other parts of the world, including the U.S. For example, California, China and Japan have all adopted
unique versions of RoHS possessing similar intent. We are actively monitoring the development of such directives
and believe we are well positioned to comply with such directives in the required time frames.

Item 1A. Risk Factors

Forward-Looking Statements

This Annual Report on Form 10-K contains forward-looking statements within the meaning of Section 27A of
the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, that
are based on information currently available to management as well as management’s assumptions and beliefs. All
statements, other than statements of historical fact, included in this Annual Report on Form 10-K constitute
forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including
but not limited to statements identified by the words “may,” “will,” “should,” “plan,” “predict,” “anticipate,”
“believe,” “intend,” “estimate” and “expect” and similar expressions. Such statements reflect our current views with
respect to future events, based on what we believe are reasonable assumptions; however, such statements are subject
to certain risks and uncertainties. In addition to the specific uncertainties discussed elsewhere in this Annual Report
on Form 10-K, the risk factors set forth below may affect our performance and results of operations. Should one or
more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results
may differ materially from those in the forward-looking statements. We disclaim any intention or obligation to
update or review any forward-looking statements or information, whether as a result of new information, future
events or otherwise.

Risk Factors

The following risk factors and other information included in this Annual Report on Form 10-K should be
carefully considered. We believe these are the principal material risks currently facing our business; however,
additional risks and uncertainties not presently known to us or that we presently deem less significant may also
impair our business operations. If any of the following risks actually occur, our business, financial condition or
results of operations could be materially adversely affected.

Global General Business, Economic and Market Conditions Could Adversely Affect Our Financial
Performance and Limit our Access to the Capital Markets

Future disruptions in U.S. or global financial and credit markets might have an adverse impact on our business.
The tightening or unavailability of credit adversely affects the ability of our customers to obtain financing for
significant purchases and operations and could result in a decrease in sales of our products and services and may
impact the ability of our customers to make payments to us. Similarly, tightening of credit may adversely affect our
supplier base and increase the potential for one or more of our suppliers to experience financial distress or
bankruptcy. Our business may also be adversely affected by future decreases in the general level of economic
activity, which may cause our customers to cancel, decrease or delay their purchases of our products and services.

If financial markets were to deteriorate, or costs of capital were to increase significantly due to a lowering of
our credit ratings, prevailing industry conditions, the volatility of the capital markets or other factors, we may be
unable to obtain new financing on acceptable terms, or at all. A deterioration in our financial performance could also
limit our future ability to access amounts currently available under our domestic revolving credit facility. In
addition, availability under our asset securitization agreement may be adversely impacted by credit quality and
performance of our customer accounts receivable. The availability under our asset securitization agreement is based

10

on the amount of accounts receivable that meet the eligibility criteria of the asset securitization agreement. If
receivable losses increase or credit quality deteriorates, the amount of eligible receivables could decline and, in turn,
lower the availability under the asset securitization.

We cannot predict the likelihood of occurrence, the duration and severity of any future disruption in financial

markets or adverse economic conditions in the U.S. and other countries.

Our Financial Performance Is Dependent on the Conditions of the U.S. Construction Industry.

Our business is affected by the performance of the U.S. construction industry. Our sales in the residential and
commercial new construction market correlate to the number of new homes and buildings that are built, which in
turn is influenced by cyclical factors such as interest rates, inflation, availability of financing, consumer spending
habits and confidence, employment rates and other macroeconomic factors over which we have no control. For the
last several years the U.S. housing industry has experienced a significant downturn, resulting in a decline in the
demand for the products and services we sell into the residential new construction market.

Cooler than Normal Summers and Warmer than Normal Winters May Depress Our Sales.

Demand for our products and for our services is strongly affected by the weather. Cooler than normal summers
depress our sales of replacement air conditioning and refrigeration products and services, and warmer than normal
winters have the same effect on our heating products and services.

Price Volatility for Commodities We Purchase or Significant Supply Interruptions Could Have an Adverse

Effect on Our Cash Flow or Results of Operations.

In the manufacture of our products, we depend on raw materials, such as steel, copper and aluminum, and
components purchased from third parties. We generally concentrate purchases for a given raw material or
component with a small number of suppliers. If a supplier is unable or unwilling to meet our supply requirements,
we could experience supply interruptions or cost increases, either of which could have an adverse effect on our
results of operations. In addition, although we regularly pre-purchase a portion of our raw materials at fixed prices
each year to hedge against price increases, an increase in raw materials prices not covered by our fixed price
arrangements could significantly increase our cost of goods sold and negatively impact our margins if we are unable
to effectively pass such price increases on to our customers. Alternatively, if we increase our prices in response to
increases in the prices or quantities of raw materials or components we require or encounter significant supply
interruptions, our competitive position could be adversely affected, which may result in depressed sales.

In addition, we use derivatives to hedge price risk associated with forecasted purchases of certain raw
materials. Our hedged price could result in our paying higher or lower prices for commodities as compared to the
market prices for those commodities when purchased. Decreases in spot prices below our hedged prices can also
require us to post letters of credit as collateral with our hedge counterparties, which would temporarily reduce our
borrowing capacity under our domestic revolving credit facility.

Our Ability to Meet Customer Demand may be Limited by Our Single-Location Production Facilities,
Reliance on Certain Key Suppliers and Unanticipated Significant Shifts in Customer Demand.

We manufacture many of our products at single-location production facilities, and we rely on certain suppliers
who also may concentrate production in single locations. Any significant interruptions in production at one or more
of our facilities, or at a facility of one of our suppliers, could negatively impact our ability to deliver our products to
our customers. Further, even with all of our facilities running at full production, we could potentially be unable to
fully meet demand during an unanticipated period of exceptionally high demand.

Our inability to meet our customers’ demand for our products could have a material adverse impact on our

business, financial condition and results of operations.

11

We May Incur Substantial Costs as a Result of Warranty and Product Liability Claims Which Could Have

an Adverse Effect on Our Results of Operations.

The development, manufacture, sale and use of our products involve risks of warranty and product liability
claims. In addition, because we own installing heating and air conditioning dealers in the U.S. and Canada, we incur
the risk of liability claims for the installation and service of heating and air conditioning products. Our product
liability insurance policies have limits that, if exceeded, may result in substantial costs that would have an adverse
effect on our results of operations. In addition, warranty claims are not covered by our product liability insurance
and certain product liability claims may also not be covered by our product liability insurance.

For some of our HVAC products, we provide warranty terms ranging from one to 20 years to customers for
certain components such as compressors or heat exchangers. For select products, we have provided lifetime
warranties for heat exchangers. Warranties of such extended lengths pose a risk to us as actual future costs may
exceed our current estimates of those costs. Warranty expense is recorded on the date that revenue is recognized and
requires significant assumptions about what costs will be incurred in the future. We may be required to record
material adjustments to accruals and expense in the future if actual costs for these warranties are different from our
assumptions.

We May Not be Able to Compete Favorably in the Highly Competitive HVACR Business.

Substantially all of the markets in which we operate are highly competitive. The most significant competitive
factors we face are product reliability, product performance, service and price, with the relative importance of these
factors varying among our product lines. Other factors that affect competition in the HVACR market include the
development and application of new technologies, an increasing emphasis on the development of more efficient
HVACR products and new product introductions. The establishment of manufacturing in low-cost countries could
also provide cost advantages to existing and emerging competitors. Our competitors may have greater financial
resources than we have, allowing them to invest in more extensive research and development and/or marketing
activity. In addition, our Service Experts segment faces competition from independent dealers and dealers owned by
utility companies and other consumer service providers, some of whom may be able to provide their products or
services at lower prices than we can. We may not be able to compete successfully against current and future
competitors and current and future competitive pressures may cause us to reduce our prices or lose market share, or
could negatively affect our cash flow, all of which could have an adverse effect on our results of operations.

There Is No Guarantee That Our Efforts to Reduce Costs Will Be Successful.

As part of our strategic priorities of manufacturing and sourcing excellence and expense reduction, we are
engaged in various manufacturing rationalization actions designed to lower our cost structure. We are reorganizing
our North American distribution network in order to better serve our customers’ needs by deploying parts and
equipment inventory closer to them. We continue to rationalize and reorganize various support and administrative
functions in order to reduce ongoing selling and administrative expenses. If we cannot successfully implement such
restructuring strategies or other cost savings plans, we may not achieve our expected cost savings in the time
anticipated, or at all. In such case, our results of operations and profitability may be negatively impaired, making us
less competitive and potentially causing us to lose market share.

We May Not be Able to Successfully Develop and Market New Products.

Our future success depends on our continued investment in research and new product development and our
ability to commercialize new technological advances in the HVACR industry. If we are unable to continue to
successfully develop and market new products or to achieve technological advances on a pace consistent with that of
our competitors, our business and results of operations could be adversely impacted.

We May Not be Able to Successfully Integrate and Operate Businesses that We May Acquire.

From time to time, we may seek to complement or expand our business through strategic acquisitions. The
success of these transactions will depend, in part, on our ability to integrate and operate the acquired businesses
profitably. If we are unable to successfully integrate acquisitions with our operations, we may not realize the

12

anticipated benefits associated with such transactions, which could adversely affect our business and results of
operations.

Because a Significant Percentage of Our Workforce is Unionized, We Face Risks of Work Stoppages and

Other Labor Relations Problems.

As of December 31, 2010, approximately 20% of our workforce was unionized. The results of future
negotiations with these unions and the effects of any production interruptions or labor stoppages could have an
adverse effect on our results of operations.

We are Subject to Litigation and Environmental Regulations that Could Have an Adverse Effect on Our

Results of Operations.

We are involved in various claims and lawsuits incidental to our business, including those involving product
liability, labor relations and environmental matters, some of which claim significant damages. Given the inherent
uncertainty of litigation, we cannot be certain that existing litigation or any future adverse legal developments will
not have a material adverse impact on our financial condition. In addition, we are subject to extensive and changing
federal, state and local laws and regulations designed to protect the environment. These laws and regulations could
impose liability for remediation costs and civil or criminal penalties in cases of non-compliance. Compliance with
environmental laws increases our costs of doing business. Because these laws are subject to frequent change, we are
unable to predict the future costs resulting from environmental compliance.

Our International Operations Subject Us to Risks Associated with Foreign Currency Fluctuations and

Changes in Local Government Regulation.

We earn revenues, pay expenses, own assets and incur liabilities in countries using currencies other than the
U.S. dollar. Because our consolidated financial statements are presented in U.S. dollars, we must translate revenues,
income and expenses, as well as assets and liabilities, into U.S. dollars at exchange rates in effect during or at the end
of each reporting period. Therefore, increases or decreases in the value of the U.S. dollar against other major
currencies may affect our net operating revenues, operating income and the value of balance sheet items
denominated in foreign currencies. Because of the geographic diversity of our operations, weaknesses in some
currencies might be offset by strengths in others over time. However, we cannot assure that fluctuations in foreign
currency exchange rates, particularly the strengthening of the U.S. dollar against major currencies, would not
materially affect our financial results.

In addition to the currency exchange risks inherent in operating in foreign countries, our international sales and
operations, including our purchases of raw materials from international suppliers, are subject to risks associated
with changes in local government laws, regulations and policies, including those related to tariffs and trade barriers,
investments, taxation, exchange controls, and employment regulations. Our international sales and operations are
also sensitive to changes in foreign national priorities, including government budgets, as well as to political and
economic instability. International transactions may involve increased financial and legal risks due to differing legal
systems and customs in foreign countries. The ability to manage these risks could be difficult and may limit our
operations and make the manufacture and sale of our products internationally more difficult, which could negatively
affect our business and results of operations.

Any Future Determination that a Significant Impairment of the Value of Our Goodwill Intangible Asset

has Occurred Could Have a Material Adverse Effect on Our Results of Operations.

As of December 31, 2010, we had goodwill of $271.8 million on our Consolidated Balance Sheet. Any future
determination that an impairment of the value of goodwill has occurred would require a write-down of the impaired
portion of goodwill to fair value, which would reduce our assets and stockholders’ equity and could have a material
adverse effect on our results of operations.

13

Declines in Capital Markets Could Necessitate Increased Cash Contributions by Us to Our Pension Plans

to Maintain Required Levels of Funding.

Volatility in the capital markets may have a significant impact on the funding status of our defined benefit
pension plans. If the performance of the capital markets depresses the value of our defined benefit pension plan
assets, our plans may be underfunded and we would have to make contributions to the pension plans. The amount of
contributions we may be required to make to our pension plans in the future is uncertain and could be significant,
which may have a material impact on our results of operations.

In addition to the properties described above, we lease over 100 facilities in the U.S. for use as sales and service
offices and district warehouses and additional facilities worldwide for use as sales and service offices and regional
warehouses. The majority of our Service Experts’ service center facilities are leased. We routinely evaluate our
production facilities to ensure adequate capacity, effective cost structure, and consistency with our business
strategy. We believe that our properties are in good condition, suitable and adequate for their present requirements
and that our principal plants are generally adequate to meet our production needs. However, certain production
facilities are operating at less than full capacity due to restructuring activities. See Note 16 to the Consolidated
Financial Statements for additional information regarding restructuring activities.

The Residential & Commercial Heating & Cooling distribution network is currently in the process of being
redesign for greater productivity, cost improvement, and customer reach. Included in the table above are our large
warehouses that hold a significant inventory balance.

Item 3. Legal Proceedings

On February 6, 2008, a class action lawsuit was filed against us in the U.S. District Court for the Northern
District of California styled Keilholtz v. Lennox Hearth Products, Inc., Lennox Industries, Inc. and Lennox
International, Inc. The lawsuit, which involves no personal injury claims, alleges that certain of our single-pane,
glass-front, gas fireplaces are hazardous and that consumers were not adequately warned, and seeks economic
damages. On February 16, 2010, the court issued an order certifying a nationwide class of plaintiffs.

On August 23, 2010, the Company and the plaintiffs entered into a binding Memorandum of Understanding
(MOU) containing tentative terms for settlement of the case. At the parties’ request, the court stayed the lawsuit
shortly after the MOU was signed. On January 11, 2011, the court granted preliminary approval of the settlement.
The court set June 2, 2011, as the date for the final approval hearing.

We are involved in a number of other claims and lawsuits incident to the operation of our businesses. Insurance
coverages are maintained and estimated costs are recorded for such claims and lawsuits. It is management’s opinion
that none of these claims or lawsuits will have a material adverse effect on our financial position, results of
operations or cash flows. Costs related to such matters were not material to the periods presented.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussions should be read in conjunction with the other sections of this report, including the

consolidated financial statements and related notes contained in Item 8 of this Annual Report on Form 10-K.

Overview

We operate in four reportable business segments of the heating, ventilation, air conditioning and refrigeration,
(“HVACR”) industry. Our reportable segments are Residential Heating & Cooling, Commercial Heating &
Cooling, Service Experts and Refrigeration. For more detailed information regarding our reportable segments,
see Note 19 in the Notes to our Consolidated Financial Statements.

Our products and services are sold through a combination of distributors, independent and company-owned
dealer service centers, other installing contractors, wholesalers, manufacturers’ representatives, original equipment
manufacturers and to national accounts. The demand for our products and services is seasonal and dependent on the
weather. Warmer than normal summer temperatures generate strong demand for replacement air conditioning and
refrigeration products and services and colder than normal winter temperatures have the same effect on heating
products and services. Conversely, cooler than normal summers and warmer than normal winters depress HVACR
sales and services. In addition to weather, demand for our products and services is influenced by national and
regional economic and demographic factors, such as interest rates, the availability of financing, regional population
and employment trends, new construction, general economic conditions and consumer spending habits and
confidence. A substantial portion of the sales in each of our business segments is attributable to replacement
business, with the balance comprised of new construction business.

The principal elements of cost of goods sold in our manufacturing operations are components, raw materials,
factory overhead, labor and estimated costs of warranty expense. In our Service Experts segment, the principal
components of cost of goods sold are equipment, parts and supplies and labor. The principal raw materials used in
our manufacturing processes are steel, copper and aluminum. In recent years, the volatility of commodity prices and
related components has impacted us and the HVACR industry in general. We endeavor to mitigate the impact of
higher commodity prices through a combination of price increases, commodity contracts, improved production

19

efficiency and cost reduction initiatives. We also partially mitigate volatility in the prices of these commodities by
entering into futures contracts and fixed forward contracts.

Company Highlights

(cid:129) Net sales for 2010 were $3,096.4 million, compared to $2,847.5 million in 2009 and were favorably

impacted by higher volumes across all segments.

(cid:129) Operational income from continuing operations for 2010 was $190.4 million compared to $109.2 million for
2009. The improvement to operational income was primarily due to higher sales volumes and productivity.

(cid:129) Net income for 2010 was $116.2 million compared to $51.1 million in 2009. Diluted earnings per share from

continuing operations was $2.10 per share in 2010 compared to $1.09 per share in 2009.

(cid:129) We generated $185.8 million of cash flow from operating activities in 2010 compared to $225.5 million in

2009.

(cid:129) During 2010, we returned $144.3 million to shareholders through share repurchases.

Year Ended December 31, 2010 Compared to Year Ended December 31, 2009 — Consolidated Results

Net Sales

Sales increased 8.7% for 2010 as compared to 2009 due to increased sales volumes of 5% primarily driven by
growth across all four business segments. Volume improved in all four reportable business segments, led by strength
in Residential Heating & Cooling and Service Experts. Price and mix of approximately 2% also had a favorable
impact on sales. Changes in foreign currency exchange rates favorably impacted net sales by 2%.

Gross Profit

Gross profit margins improved approximately 110 basis points to 28.8% for 2010, compared to gross profit
margins of 27.7% in 2009. This improvement was primarily driven by lower product costs from material savings
and manufacturing efficiencies of approximately 140 basis points. Gross profit margin comparisons were also
favorably impacted by 60 basis points for expenses related to a product quality issue that were recorded in 2009 with
no such expenses in 2010. Partially offsetting these positive impacts to gross profit margins were commodities
headwinds of 50 basis points and increased freight and distribution expenses that decreased gross profit margins by
approximately 50 basis points primarily in the Residential Heating & Cooling segment.

21

Selling, General and Administrative Expenses

Selling, general and administrative (“SG&A”) expenses increased by $40.8 million in 2010 as compared to
2009, and as a percentage of sales, SG&A expenses were down 50 basis points from 22.6% in 2009 to 22.1% in
2010. SG&A expenses increased $16 million due to increased variable incentive compensation driven by improved
financial performance and $35 million related to increased variable selling, advertising, and promotion expenses in
support of our sales growth. These increases were partially offset by lower bad debt expense and pension costs.

Losses (Gains) and Other Expenses, Net

Losses (gains) and other expenses, net for 2010 and 2009 included the following (in millions):

$(6.6)

The change in gains and losses on settled futures contracts was primarily due to increases in commodity prices
relative to the futures contract prices during 2010 as compared to 2009. Conversely, the change in unrealized gains
related to unsettled futures contracts was primarily due to lower commodity prices relative to the futures contract
prices for those contracts. For more information, see Note 8 in the Notes to the Consolidated Financial Statements.
For more information regarding the special legal contingency charge, see Note 10 in the Notes to the Consolidated
Financial Statements. Acquisition expenses relate to an acquisition consummated subsequent to year end. For more
information, see Note 24 in the Notes to the Consolidated Financial Statements.

Restructuring Charges

Restructuring charges were $15.6 million in 2010 compared to $41.5 million in 2009. The lower restructuring
charges in 2010 were primarily due to a smaller number of large projects in 2010. The restructuring charges in 2010
primarily consisted of manufacturing rationalization projects in Australia in the Refrigeration segment which
totaled $8.6 million as well as administrative reorganizations in our Service Experts segment which totaled
$2.1 million. The remaining restructuring charges in 2010 were primarily related to projects announced prior to
2010. Restructuring charges in 2009 primarily consisted of three large manufacturing rationalization projects
totaling $25.2 million and $11.3 million in various corporate and business unit administrative reorganizations. For a
detailed discussion regarding restructuring activities, see Note 16 in the Notes to the Consolidated Financial
Statements.

Income from Equity Method Investments

Investments over which we do not exercise control but have significant influence are accounted for using the
equity method of accounting. Income from equity method investments increased to $10.1 million in 2010 as
compared to $7.3 million in 2009 primarily due to the improved performance of our U.S. joint venture in
compressor manufacturing, which experienced increased sales and profitability.

22

Interest Expense, net

Interest expense, net increased to $12.8 million in 2010 as compared to $8.2 million in 2009. The increase in
interest expense was primarily attributable to higher debt levels, and the issuance of $200 million of our senior
unsecured notes at 4.91% with a higher interest rate than our revolver.

Income Taxes

The income tax provision was $59.5 million in 2010 as compared to $39.1 million in 2009. The effective tax
rate was 33.7% for 2010 as compared to 38.8% for 2009. Our effective rates differ from the statutory federal rate of
35% for certain items, such as state and local taxes, non-deductible expenses, foreign operating losses for which no
tax benefits have been recognized and foreign taxes at rates other than 35%.

Discontinued Operations

During 2008 and 2009, we announced plans to sell twelve service centers. We sold all of these service centers

during 2009 and 2010.

The pre-tax operating loss from discontinued operations was $1.1 million in 2010 as compared to $13.1 million
in 2009. Included in the 2009 loss from discontinued operations was an impairment charge of $2.7 million related to
service centers where the estimated selling price of the assets was below the net book value of those assets, gains on
disposal of assets and liabilities of $2.3 million, and a write-off of $4.0 million of goodwill related to the sale of
these service centers.

The increase in sales was due to the recovery of the U.S. residential end markets, primarily the replacement
market. Sales volumes increased net sales by 8% in 2010 as compared to 2009, while price and mix were relatively
flat at a 1% increase. The positive impact of changes in foreign currency exchange rates also increased sales by 1%.

Segment profit increased $20.6 million, including $25 million due to the increase in sales and $14 million due
to material savings and manufacturing efficiencies partially offset by commodities headwinds of $9 million. These
were partially offset by higher SG&A expenses of $14 million consisting primarily of increased variable selling
expenses and incentive compensation.

Our Commercial Heating & Cooling business experienced increased sales volumes of nearly 3% during 2010
primarily due to introductions of energy efficient products and an increase in planned replacement business at
national retail accounts as well as strong growth in the schools market. Price and mix were favorable by 2%. Foreign
currency exchange rates decreased sales by 1%.

Segment profit increased $20.0 million, including nearly $19 million due to the increase in net sales and
$3 million due to material savings and manufacturing efficiencies. These increases were partially offset by higher
SG&A expenses of $3 million consisting primarily of increased variable selling expenses and incentive
compensation.

due to an increase in sales volumes of 5%. Price and mix increased sales by 3%. Foreign currency exchange rates
increased sales by 2%.

Segment profit increased $2.7 million, including nearly $6 million due to the increase in sales. Higher selling

expenses of $3 million partially offset the favorable effect of higher revenues.

Segment profit increased $12.5 million, including $10 million due to the increase in sales and almost
$3 million in improved material savings and manufacturing efficiencies as those factors more than offset
commodity price pressures.

Corporate and Other

Corporate and other expenses were $65.5 million in 2010, up from $62.5 million in 2009. The increase was
primarily driven by increases in stock-based and incentive compensation expenses of approximately $8 million,
partially offset by lower pension costs of approximately $4 million.

Year Ended December 31, 2009 Compared to Year Ended December 31, 2008 — Consolidated Results

Net Sales

Net sales decreased 17.3% for 2009 as compared to 2008. The decrease in net sales was due to decreased sales
volumes of approximately 18% across all segments and was driven by declines in the overall end markets we serve.
For the year, we saw rates of decline increase across all segments. However, our end markets showed improvement
late in the year and particularly in the fourth quarter, with our residential HVAC end markets showing growth in the
fourth quarter. The commercial HVAC and refrigeration markets were still down from a year ago, but the rate of
decline continued to slow in the fourth quarter. The declines in unit volumes were partially offset by pricing gains of
approximately 1% and positive sales mix of almost 1%. Changes in foreign currency exchange rates adversely
impacted revenues by 1%.

Gross Profit

Gross profit margins improved 50 basis points to 27.7% for 2009, compared to gross margins of 27.2% in 2008.
Gross profit margins improved by approximately 150 basis points due to pricing actions. Lower product costs
favorably impacted our gross profit margins as material savings were offset by increases in other product costs,
including under-absorbed overhead on lower volume and distribution costs. A charge for a product quality issue
lowered gross profit margins by 80 basis points in 2009.

Selling, General and Administrative Expenses

Selling, general and administrative (“SG&A”) expenses decreased by approximately $42.0 million in 2009 as
compared to 2008 and as a percentage of total net sales, SG&A expenses were 22.6% for 2009 and 20.0% for 2008.
Expenses decreased generally due to cost reductions, including headcount savings, totaling $35 million, and the
impact of changes in foreign exchange rates of $12 million. In the comparison of 2009 to 2008, the positive impact
in 2008 of a $10 million one-time change in our vacation policy partially offset these reductions to SG&A expenses.
Research and development expenses increased slightly as we continued to invest in future product offerings.

Losses (Gains) and Other Expenses, Net

Gains and other expenses, net for 2009 and 2008 included the following (in millions):

$(1.9)

The change in gains and losses on futures contracts was primarily due to decreases in commodity prices
relative to the futures contract prices during 2009 as compared to 2008 for the contracts that settled during the
period. Conversely, the change in unrealized (gains) losses related to unsettled futures contracts not designated as
cash flow hedges was primarily due to higher commodity prices relative to the futures contract prices for those
contracts. Gains and Other Expenses, net for 2009 includes a net gain on the sale of a European business in our
Commercial Heating & Cooling segment. We sold assets totaling $5.9 million and recorded a net loss of
$2.7 million, after related transaction costs. Upon liquidation of this business, we recorded previously deferred
currency gains of $6.8 million. Gains on disposal of fixed assets in 2008 included gains recorded on the sale-
leaseback of two properties located in North America in 2008. No such transactions occurred in 2009. The change in

25

foreign currency losses (gains) was primarily due to a favorable catch-up adjustment of $4.5 million related to
foreign currency fluctuations on intercompany loans recorded in 2008. For more information, see Note 22 in the
Notes to the Consolidated Financial Statements.

Restructuring Charges

Restructuring charges were $41.5 million in 2009 compared to $30.4 million in 2008. In 2009, we announced
three large manufacturing rationalization projects which included $9.7 million for the closure of the Blackville,
South Carolina facility, $7.8 million for the closure of our Parets, Spain facility, and $7.7 million for the closure of
our Mions, France facility. In addition, we had $11.3 million in restructuring charges in 2009 related to various
reorganizations of corporate and business unit administrative functions. Restructuring charges in 2009 were higher
than 2008 due to the number of large restructuring projects in 2009. We realized approximately $24 million from
restructuring savings in 2009. For a detailed discussion regarding restructuring activities, see Note 16 in the Notes to
the Consolidated Financial Statements.

Impairment of Assets

In 2009, we recorded $6.0 million in impairment charges related to the abandonment of information
technology assets that had not yet been placed in service due to our significant restructuring activities and our
exiting of a business in the European region.

In 2008, we recorded $9.1 million of impairment charges related to our investment in a joint venture in
Thailand. The carrying value of this investment at year-end 2008 was $1.8 million and, due to a loss of significant
influence over the venture, it was no longer accounted for under the equity method in 2009.

Results from Equity Method and Other Equity Investments

Investments over which we do not exercise control but have significant influence are accounted for using the
equity method of accounting. Income from equity method investments decreased to $7.3 million in 2009, compared
to $8.6 million in 2008, primarily due to a decrease in the performance of our Mexican joint venture and our
U.S. joint venture in compressor manufacturing due to lower sales volumes.

Interest Expense, Net

Interest expense, net, decreased to $8.2 million in 2009 from $14.2 million in 2008. The decrease in interest
expense was primarily attributable to a decrease in the average amounts borrowed in 2009 as compared to 2008, and
the remainder of the decrease is due to a lower interest rate paid on variable rate debt.

Provision for Income Taxes

The income tax provision was $39.1 million in 2009, compared to $80.5 million in 2008. The effective tax rate
was 38.8% for 2009 as compared to 39.4% for 2008. Our effective rates differ from the statutory federal rate of 35%
for certain items, such as state and local taxes, non-deductible expenses, foreign operating losses for which no tax
benefits have been recognized and foreign taxes at rates other than 35%.

Discontinued Operations

We have reclassified a pre-tax loss of $13.1 million in 2009 as discontinued operations as compared to a pre-
tax loss of $1.8 million during 2008. Included in the 2009 loss from discontinued operations was an impairment
charge of $2.7 million related to service centers where the estimated selling price of the assets was below the net
book value of those assets, gains on disposal of assets and liabilities of $2.3 million, and a write-off of $4.0 million
of goodwill related to the sale of these service centers. The loss from discontinued operations in 2008 included a
provision of $4.4 million for an unfavorable judgment in litigation related to the sale of a service center in 2004 that
was included in discontinued operations. This contingency was settled in 2009 for $6.1 million.

The decrease in net sales was due to continuing weakness early in 2009 in the U.S. residential new construction
market and softer replacement business as consumers remained cautious due to the economic environment. Sales
from the Hearth business within Residential Heating & Cooling continued to be down significantly. However, sales
to the residential HVAC end markets showed improvement late in the year and particularly in the fourth quarter,
with our residential HVAC end markets showing growth in the fourth quarter. Reduced sales volumes decreased net
sales by nearly 15% in 2009 as compared to 2008. The unfavorable impact of changes in foreign currency exchange
rates also decreased net sales by almost 1%. The decrease in net sales was partially offset by pricing gains of almost
2% related to increases that were enacted in the later quarters of 2008. Our sales mix was flat.

Segment profit declined $30 million due to a decrease in net sales. The decrease in 2009 was also partially due
to the positive impact in 2008 of a $7 million one-time change in our vacation policy and gains related to the sale-
leaseback of two properties of $4 million. The decline in segment profit was partially offset by lower product costs
of $4 million resulting from material savings partially offset by increases in other product costs, including under-
absorbed manufacturing overhead, and SG&A cost reductions, including headcount savings, of $7 million.

In 2009, a $24.4 million charge related to a vendor-supplied materials quality issue was not included in our

Residential Heating & Cooling segment’s profit as it is considered an unusual and nonrecurring item.

Our Commercial Heating & Cooling business experienced lower sales volumes of 31%, primarily due to weak
new construction in North America and overall weakness in European business. The unfavorable impact of changes
in foreign currency exchange rates on net sales was 2%. As an offset to these negative impacts, sales mix was
positive at 4%. Pricing was flat for 2009.

Segment profit declined $59 million due to a decrease in net sales. The unfavorable comparison of 2009 to
2008 was also partially due to the positive impact in 2008 of a $4 million one-time change in our vacation policy.
These declines were partially offset by lower product costs of $5 million resulting from material savings partially
offset by increases in other product costs, including under-absorbed manufacturing overhead. SG&A cost reduc-
tions, including headcount savings, of over $15 million partially also offset the decline in segment profit.

The decrease in net sales was primarily due to the decline in the residential new construction and residential
service and replacement end markets resulting from the weakness of the U.S. economy. The sales decrease was
primarily due to a decrease in sales volumes of 7% as both price and sales mix were flat. The unfavorable impact of
changes in foreign currency exchange rates decreased net sales by 1%.

Segment profit declined $9 million due to a decrease in net sales. Reduced costs of sales of $2 million due to
lower fuel costs and increased technician productivity and SG&A cost reductions, including headcount savings, of
almost $5 million partially offset this decline.

Net sales decreased due to lower sales volumes of 16% and the unfavorable impact of changes in foreign

currency exchange rates of 3%. Pricing gains of approximately 2% partially offset these negative impacts.

Segment profit declined $21 million due to a decrease in net sales and increased product costs of $1 million, as
other product costs, including under-absorbed manufacturing overhead, more than offset materials savings in 2009.
Offsetting these unfavorable impacts were SG&A cost reductions, including headcount savings, of $10 million.

Corporate and Other

Corporate and other expenses increased to $62.5 million in 2009, up from $53.8 million in 2008. Comparisons
to the prior year were affected by a favorable adjustment for foreign currency exchange rates of approximately
$4.5 million that was recorded in the second quarter of 2008.

Accounting for Futures Contracts

Realized gains and losses on settled futures contracts are a component of segment profit (loss). Unrealized
gains and losses on open futures contracts are excluded from segment profit (loss) as they are subject to changes in
fair value until their settlement date. Both realized and unrealized gains and losses on futures contracts are a
component of Losses (Gains) and Other Expenses, net in the accompanying Consolidated Statements of Operations.
See Note 19 to our Consolidated Financial Statements for more information and a reconciliation of segment profit to
net income.

Liquidity and Capital Resources

Our working capital and capital expenditure requirements are generally met through internally generated
funds, bank lines of credit and a revolving period asset securitization arrangement. Working capital needs are
generally greater in the first and second quarters due to the seasonal nature of our business cycle.

Net cash provided by operating activities

During 2010, cash provided by operating activities was lower than in 2009 primarily due to increased working
capital needs in support of our sales growth. An increase in accounts receivable resulted in a cash use of
$29.3 million and an increase in inventories resulted in a cash use of $31.1 million. This was partially offset by
increased accounts payable of $33.6 million. Increased net income of $116.2 million in 2010 up from $51.1 million
in 2009 partially offset these unfavorable working capital impacts to operating cash flows.

We contributed $5.6 million to our defined benefit pension plans in 2010 as compared to $42.2 million in 2009.
We made no payments on our asset securitization program in 2010 as compared to payments of $30.0 million in
2009. We received cash of $37.9 million in 2009 from collateral previously posted related to commodity hedge
derivative loss positions in 2008, partially offsetting the positive impacts on operating cash flows in 2010 compared
to 2009. We paid $26.6 million for restructuring activities in 2010 resulting in a negative impact on operating cash
flows of $11.0 million in 2010 as compared to an $18.6 million source of cash in 2009.

Net cash used in investing activities

Net cash used in investing activities in 2010 increased due to the net purchase of businesses of $3.6 million and
restricted cash of $12.2 million. Investing activities in 2009 included net cash of $10.0 million from the sale of
businesses and the net positive cash flow impact of $33.3 million for net short-term investments which negatively
impacted the comparison of 2010 investing cash flow to those experienced in 2009. Capital expenditures were
$45.8 million, $58.8 million and $62.1 million in 2010, 2009 and 2008, respectively. In 2010 capital expenditures
were lower due to project timing and are anticipated to increase in 2011 to similar levels as 2009 and 2008. On
January 14, 2011, we paid $145.2 million, including a purchase price working capital adjustment, to complete the
Kysor/Warren acquisition.

Net cash used in financing activities

Net borrowings of long-term debt, short-term borrowings and revolving long-term payments totaled approx-
imately $86.6 million in 2010 compared to net payments of $189.3 million in 2009. During 2010, we used
approximately $144.3 million to repurchase approximately 3.3 million shares of our common stock under our share
repurchase plans.

Debt Position and Financial Leverage

Our debt-to-total capital ratio increased to 35.1% as of December 31, 2010 from 27.7% as of December 31,
2009 due to higher outstanding debt. For a detailed description regarding our debt including our debt covenants, see
Note 11 in the Notes to the Consolidated Financial Statements.

As of December 31, 2010, we had outstanding long-term debt obligations totaling $317.0 million, which
increased from $193.8 million as of December 31, 2009. The amount outstanding as of December 31, 2010

29

consisted primarily of outstanding borrowings of $100.0 million under our domestic revolving credit facility, which
matures in 2012, and $200.0 million of senior unsecured notes.

As of December 31, 2010, we had outstanding borrowings of $100.0 million under our $650.0 million
domestic revolving credit facility and $69.5 million was committed to standby letters of credit. The remaining
$480.5 million was available for future borrowings subject to covenant limitations. The facility matures in October
2012. As of December 31, 2010, we were in compliance with all covenant requirements.

Our domestic revolving credit facility includes a subfacility for swingline loans of up to $50.0 million and
provides for the issuance of letters of credit for the full amount available under the domestic revolving credit facility.
Our weighted average borrowing rate on the domestic revolving credit facility was 0.96% and 0.84% as of
December 31, 2010 and 2009, respectively.

Our domestic revolving credit facility contains financial covenants relating to leverage and interest coverage.
Other covenants contained in our domestic revolving credit facility restrict, among other things, mergers, asset
dispositions, guarantees, debt, liens, acquisitions, investments, affiliate transactions and our ability to make
restricted payments. The financial covenants require us to maintain defined levels of Consolidated Indebtedness
to Adjusted EBITDA Ratio and a Cash Flow (defined as EBITDA minus capital expenditures) to Net Interest
Expense Ratio. The required ratios as of December 31, 2010 are detailed below:

Consolidated Indebtedness to Adjusted EBITDA Ratio not greater than . . . . . . . . . . . . . . . . . . . . . . 3.5 : 1.0
Cash Flow to Net Interest Expense Ratio no less than . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.0 : 1.0

Our domestic revolving credit facility contains customary events of default. These events of default include
nonpayment of principal or interest, breach of covenants or other restrictions or requirements, default on any other
indebtedness or receivables securitizations (cross default), and bankruptcy. A cross default under our revolving
credit facility could occur if:

(cid:129) we fail to pay any principal or interest when due on any other indebtedness or receivables securitization of at

least $40.0 million; or

(cid:129) we are in default in the performance of, or compliance with any term of any other indebtedness or receivables
securitization in an aggregate principal amount of at least $40.0 million, or any other condition exists which
would give the holders the right to declare such indebtedness due and payable prior to its stated maturity.

Each of our major debt agreements contains provisions by which a default under one agreement causes a
default in the others (a cross default). If a cross default under the revolving credit facility, our senior unsecured
notes, or our revolving period asset securitization program were to occur, it could have a wider impact on our
liquidity than might otherwise occur from a default of a single debt instrument or lease commitment.

If any event of default occurs and is continuing, lenders with a majority of the aggregate commitments may
require the administrative agent to terminate our right to borrow under our domestic revolving credit facility and
accelerate amounts due under our domestic revolving credit facility (except for a bankruptcy event of default, in
which case such amounts will automatically become due and payable and the lenders’ commitments will
automatically terminate).

On May 6, 2010, we issued $200.0 million of senior unsecured notes due May 15, 2017 bearing fixed interest at
4.90% as a result of a public offering of securities. We received proceeds of $199.8 million from the offering for a
yield of 4.91%. We also paid and capitalized $1.9 million of debt issue costs related to the issuance. We pay interest
on the notes semiannually on May 15 and November 15.

The proceeds from the issuance were used to repay outstanding indebtedness under our domestic revolving
credit facility, working capital and other general corporate purposes, including repurchases of shares of our
common stock pursuant to our previously announced share repurchase plans.

Upon a change of control, holders of our notes will have the right to require us to repurchase all or a portion of
the senior unsecured notes at a repurchase price equal to 101% of the principal amount of the notes repurchased,
plus accrued and unpaid interest, if any. The notes are guaranteed, on a senior unsecured basis, by each of our
domestic subsidiaries that guarantee payment by us of any indebtedness under our domestic revolving credit

facility. The indenture governing the notes contains covenants that, among other things, limit our ability and the
ability of the subsidiary guarantors to: create or incur certain liens; enter into certain sale and leaseback
transactions; enter into certain mergers, consolidations and transfers of substantially all of our assets; and transfer
certain properties. The indenture also contains a cross default provision which is triggered if we default on other
debt of at least $75 million in principal which is then accelerated, and such acceleration is not rescinded within
30 days of the notice date.

Under a revolving period asset securitization arrangement (“ASA”), we are eligible to transfer beneficial
interests in a portion of our trade accounts receivable to third parties in exchange for cash. Our continued
involvement in the transferred assets includes servicing, collection and administration of the transferred beneficial
interests. The sale of the beneficial interests in our trade accounts receivable are reflected as secured borrowings.
The fair values assigned to the retained and transferred interests are based primarily on the receivables’ carrying
value given the short term to maturity and low credit risk. The ASA provides for a maximum securitization amount
of $100 million or 100% of the net pool balance as defined by the ASA. However, eligibility for securitization is
limited based on the amount and quality of the qualifying accounts receivable and is calculated monthly. The
beneficial interest sold cannot exceed the maximum amount even if our qualifying accounts receivable is greater
than the maximum amount at any point in time. The eligible amounts available and beneficial interests sold were as
follows (in millions):

As of December 31, 2010, $12.2 million of cash and cash equivalents were restricted and held in a trust for our

captive insurance subsidiary.

We periodically review our capital structure, including our primary bank facility, to ensure that it has adequate
liquidity. We believe that cash flows from operations, as well as available borrowings under our revolving credit
facility and other existing sources of funding, will be sufficient to fund our operations for the foreseeable future and
share repurchases under the terms of our 2008 Share Repurchase Plan.

During the third quarter of 2008, we amended the lease agreement for our corporate headquarters. While the
same party continues to be the lessor under the lease, the amendment, among other things, replaced the debt
participant and moderately increased the rent payments. The amendment also provides for financial covenants
consistent with our domestic revolving credit agreement and we are in compliance with these financial covenants.
The lease will continue to be accounted for as an operating lease.

During 2008, we expanded our Tifton, Georgia manufacturing facility using the proceeds from Industrial
Development Bonds (“IDBs”). We entered into a lease agreement with the owner of the property and the issuer of
the IDBs, and through our lease payments fund the interest payments to investors in the IDBs. We also guaranteed
the repayment of the IDBs and entered into letters of credit totaling $15.5 million to fund a potential repurchase of
the IDBs in the event that investors exercised their right to tender the IDBs to the Trustee. As of December 31, 2010
and 2009, we recorded both a long-term asset and a corresponding long-term obligation of $14.3 million related to
these transactions.

Off Balance Sheet Arrangements

In addition to the credit facilities and promissory notes described above, we also lease real estate and
machinery and equipment pursuant to operating leases that are not capitalized on the balance sheet, including high-
turnover equipment such as autos and service vehicles and short-lived equipment such as personal computers. Rent
expense for these leases was $64.3 million, $64.4 million and $64.2 million in 2010, 2009 and 2008, respectively.

As of December 31, 2010, the liability for uncertain tax positions, including interest and penalties, was
$1.1 million. Due to the uncertainty regarding the timing of payments associated with these liabilities, we are unable
to make a reasonable estimate of the amount and period in which these liabilities might be paid.

Purchase obligations consist of aluminum commitments. The above table does not include retirement,
postretirement and warranty liabilities because it is not certain when these liabilities will be funded. For additional
information regarding our contractual obligations, see Note 10, Note 11 and Note 12 of the Notes to the
Consolidated Financial Statements. Contractual obligations related to capital leases as of December 31, 2010
were included as part of long-term debt in the table above.

Fair Value Measurements

Fair Value Hierarchy

The three-level fair value hierarchy for disclosure of fair value measurements are defined as follows:

Level 1 — Quoted prices for identical instruments in active markets at the measurement date.

Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar
instruments in markets that are not active; and model-derived valuations in which all significant
inputs and significant value drivers are observable in active markets at the measurement date and
for the anticipated term of the instrument.

Level 3 — Valuations derived from valuation techniques in which one or more significant inputs or significant
value drivers are unobservable inputs that reflect the reporting entity’s own assumptions about the
assumptions market participants would use in pricing the asset or liability developed based on the
best information available in the circumstances.

Fair Value Techniques

General

Our valuation techniques are applied to all of the assets and liabilities carried at fair value. Where available, the
fair values are based upon quoted prices in active markets. However, if quoted prices are not available, then the fair
values are based upon quoted prices for similar assets or liabilities or independently sourced market parameters,
such as credit default swap spreads, yield curves, reported trades, broker/dealer quotes, interest rates and benchmark
securities. For assets and liabilities with a lack of observable market activity, if any, the fair values are based upon
discounted cash flow methodologies incorporating assumptions that, in our judgment, reflect the assumptions a
marketplace participant would use. To ensure that financial assets and liabilities are recorded at fair value, valuation
adjustments may be required to reflect either party’s creditworthiness and ability to pay. Where appropriate, these
amounts were incorporated into our valuations as of December 31, 2010 and 2009, the measurement dates.

32

Derivatives

Derivatives are primarily valued using estimated future cash flows that are based directly on observed prices
from exchange-traded derivatives and, therefore, have been classified as Level 2. We also take into account the
counterparty’s creditworthiness, or our own creditworthiness, as appropriate. An adjustment has been recorded in
order to reflect the risk of credit default, but these adjustments have been insignificant to the overall value of the
derivatives.

Pension Plan Assets

The majority of our commingled pool/collective trust, mutual funds and balanced pension trusts are managed
by professional investment advisors. The net asset values (“NAV”) per share are furnished in monthly and/or
quarterly statements received from the investment advisors and reflect valuations based upon their pricing policies.
We have assessed the classification of the inputs used to value these investments at Level 1 for mutual funds and
Level 2 for commingled pool/collective trusts and balance pension trusts through examination of their pricing
policies and the related controls and procedures. The fair values we report are based on the pool or trust’s NAV per
share. The NAV’s per share are calculated periodically (daily or no less than one time per month) as the aggregate
value of each pool or trust’s underlying assets divided by the number of units owned.

Market Risk

Commodity Price Risk

We enter into commodity futures contracts to stabilize prices expected to be paid for raw materials and parts
containing high copper and aluminum content. These contracts are for quantities equal to or less than quantities
expected to be consumed in future production.

Fluctuations in metal commodity prices impact the value of the derivative instruments that we hold. When
metal commodity prices rise, the fair value of our futures contracts increases and conversely, when commodity
prices fall, the fair value of our futures contracts decreases.

related to our metal commodity hedges is presented below (in millions):

Interest Rate Risk

Our results of operations can be affected by changes in interest rates due to variable rates of interest on our

revolving credit facilities, cash, cash equivalents and short-term investments.

In order to partially mitigate interest rate risk, we use a hedging strategy to eliminate the variability of cash
flows in the interest payments for the first $100 million of the total variable-rate debt outstanding under the
domestic revolving credit facility that is solely due to changes in the benchmark interest rate. This strategy allows us
to fix a portion of our interest payments while also taking advantage of historically low interest rates.

On June 12, 2009, we entered into a $100 million pay-fixed, receive-variable interest rate swap with a large
financial institution at a fixed interest rate of 2.66%. The variable portion of the interest rate swap is tied to 1-Month
LIBOR (the benchmark interest rate). The interest rates under both the interest rate swap and the underlying debt are
reset, the swap is settled with the counterparty, and interest is paid, on a monthly basis. The interest rate swap
expires October 12, 2012. We account for the interest rate swap as a cash flow hedge.

Foreign Currency Exchange Rate Risk

Our results of operations can be affected by changes in exchange rates. Net sales and expenses in foreign
currencies are translated into U.S. dollars for financial reporting purposes based on the average exchange rate for the
period. During 2010, 2009 and 2008, net sales from outside the U.S. represented 27.2%, 28.6% and 29.4%,
respectively, of our total net sales. Historically, foreign currency transaction gains (losses) have not had a material
effect on our overall operations. As of December 31, 2010, the impact to net income of a 10% change in exchange
rates is estimated to be approximately $4.4 million.

Critical Accounting Policies

The preparation of financial statements requires the use of judgments and estimates. The critical accounting
policies are described below to provide a better understanding of how we develop our judgments about future events
and related estimations and how such policies can impact our financial statements. A critical accounting policy is
one that requires difficult, subjective or complex estimates and assessments and is fundamental to the results of
operations. We consider our most critical accounting policies to be:

(cid:129) goodwill and other intangible assets;

(cid:129) product warranties;

(cid:129) pension and postretirement benefits;

(cid:129) self-insurance expense;

(cid:129) derivative accounting; and

(cid:129) income taxes.

This discussion and analysis should be read in conjunction with our Consolidated Financial Statements and

related Notes in “Item 8. Financial Statements and Supplementary Data.”

Goodwill and Other Intangible Assets

We assign goodwill to the reporting units that benefit from the synergies of our acquisitions, which are the
reporting units that report the results of such acquisitions. If we reorganize our management structure, the related
goodwill is allocated to the affected reporting units based upon the relative fair values of those reporting units.
Assets and liabilities, including deferred income taxes, are generally directly assigned to the reporting units through
our segment reporting system as part of our financial closing process. However, certain assets and liabilities,
including information technology assets and pension, self-insurance, and environmental liabilities, are commonly
managed and are not allocated to the segments in the normal course of our financial reporting process and therefore
must be assigned to the reporting units based upon appropriate methods. We test goodwill for impairment by
reporting unit annually in the first quarter of each fiscal year.

Reporting units that we test are generally equivalent to our business segments, or in some cases, one level
below. We review our reporting unit structure each year as part of our annual goodwill impairment testing and
reporting units are determined based upon a review of the periodic financial information supplied to and reviewed
by our Chief Executive Officer (the chief operating decision maker). We aggregate operating units reviewed into
reporting units when those operating units share similar economic characteristics.

34

We estimate reporting unit fair values using standard business valuation techniques such as discounted cash
flows and reference to comparable business transactions. The discounted cash flow approach is the principal
technique we use. We use comparable business transactions as a reasonableness test of our principal technique as we
believe that the discounted cash flow approach provides greater detail and opportunity to reflect specific facts,
circumstances and economic conditions for each reporting unit. Comparable business transactions are often limited
in number, the information can be dated, and may require significant adjustments due to differences in the size of the
business, markets served, product offered, and other factors. We therefore believe that in our circumstances, this
makes comparisons to business transactions less reliable than the discounted cash flows method.

The discounted cash flows used to estimate fair value are based on assumptions regarding each reporting unit’s
estimated projected future cash flows and the estimated weighted-average cost of capital that a market participant
would use in evaluating the reporting unit in a purchase transaction. The estimated weighted-average cost of capital
is based on the risk-free interest rate and other factors such as equity risk premiums and the ratio of total debt to
equity capital. In performing these impairment tests, we take steps to ensure that appropriate and reasonable cash
flow projections and assumptions are used. We reconcile our estimated enterprise value to our market capitalization
and determine the reasonableness of the cost of capital used by comparing to market data. We also perform
sensitivity analyses on the key assumptions used, such as the weighted-average cost of capital and terminal growth
rates.

In the aggregate, there has been an excess of fair value over the carrying value of the net assets of our reporting
units of over $1.0 billion in both 2010 and 2009. The average rate used to discount the estimated cash flows for each
reporting unit was 10.1% in 2010 and 11.2% in 2009.

Below is a sensitivity analysis regarding the aggregate fair value of our reporting units to changes in average

discount rates for 2010 (in millions):

Approximate decrease in fair value from a 100 basis point increase in discount rate . . . . . . . $(400)
Approximate increase in fair value from a 100 basis point decrease in discount rate . . . . . . . $ 600

We also monitor economic, legal, regulatory and other factors for LII as a whole and for each reporting unit
between annual impairment tests to ensure that there are no indicators that make it more likely than not that there
has been a decline in the fair value of the reporting unit below its carrying value. Specifically, we monitor industry
trends, our market capitalization, recent and forecasted financial performance of our reporting units, and the timing
and nature of our restructuring activities. While our recent financial performance is below historical levels, we do
not currently believe that there are any indicators of impairment. If these estimates or the related assumptions
change, we may be required to record non-cash impairment charges for these assets in the future.

Product Warranties

The estimate of our liability for future warranty costs requires us to make significant assumptions about the
amount, timing and nature of the costs we will incur in the future. As some of the warranties we issue extend
10 years or more in duration, a relatively small adjustment to an assumption may have a significant impact on our
overall liability. We review the assumptions used to determine the liability periodically and we adjust our
assumptions based upon factors such as actual failure rates and cost experience. Numerous factors could affect
actual failure rates and cost experience, including the amount and timing of new product introductions, changes in
manufacturing techniques or locations, components or suppliers used. Should actual warranty costs differ from our
estimates, we may be required to record adjustments to accruals and expense in the future. For more information see
Note 10 in the Notes to the Consolidated Financial Statements.

Pensions and Postretirement Benefits

We have domestic and foreign pension plans covering essentially all employees and we also maintain an
unfunded postretirement benefit plan, which provides certain medical and life insurance benefits to eligible
employees. In order to calculate the liability and the expense for the plans, we have to make several assumptions
including the discount rate and expected return on assets. The assumed discount rates of 5.47% for pension benefits
of our U.S. qualified pension plans and 5.30% for other benefits were used to calculate the liability as of

35

December 31, 2010. Our assumed discount rates are selected using the yield curve for high-quality corporate bonds,
which is dependent upon risk-free interest rates and current credit market conditions. In 2010, we have utilized
8.00% as the assumed long-term rate of return on assets, which is 25 basis points lower than our 2009 estimate.
These are long-term estimates of equity values and are not dependent on short-term variations of the equity markets.
Differences between actual experience and our assumptions are quantified as actuarial gains and losses. These
actuarial gains and losses do not immediately impact our earnings as they are deferred in accumulated other
comprehensive income (“AOCI”) and are amortized into net periodic benefit cost over the estimated service period.
For two of our pension plans, nearly all of the participants were considered inactive because the plan benefits were
frozen by the company. As a result, we increased the amortization term for these plans from the remaining service
lives of participants to their average life expectancy. The change in amortization term had a favorable $3.4 million
impact to expense. The timing and amount of our contributions also impact funding levels and the expected return
on assets. In 2010, we contributed $5.6 million to our pension plans and we contributed $42.2 million in 2009.

The assumed long-term rate of return on assets and the discount rate have significant effects on the amounts
reported for our defined benefit plans. A 25 basis point decrease in the long-term rate of return on assets or discount
rate would have the following effects (in millions):

Assumed healthcare cost trend rates have a significant effect on the amounts reported for our healthcare plan.
For 2010, our assumed healthcare cost trend rate was 8.50%. In 2010, we lengthened our assumption regarding the
decline in healthcare cost trend assumption to the ultimate trend rate of 5.0% from 8 to 10 years A one percentage-
point change in assumed healthcare cost trend rates would have the following effects (in millions):

Should actual results differ from our estimates and assumptions, revisions to the benefit plan liabilities and the
related expenses would be required. For more information, see Note 12 in the Notes to our Consolidated Financial
Statements.

Self-Insurance Expense

We use a combination of third-party insurance and self-insurance plans (large deductible or captive) to provide
protection against claims relating to workers’ compensation/employers’ liability, general liability, product liability,
auto liability, auto physical damage and other exposures. Prior to the third quarter of 2009, these policies were
written by a third-party insurance provider, which was then reinsured by our captive insurance subsidiary. Starting
with the third quarter of 2009, we use large deductible insurance plans for workers’ compensation/employers’
liability, general liability, product liability, and auto liability. These policies are written through third-party
insurance providers. We also carry umbrella or excess liability insurance for all third-party and self-insurance
plans, except for directors’ and officers’ liability, property damage and various other insurance programs. We
believe the limit within our excess policy is adequate for companies of our size in our industry. We believe that the
deductibles and liability limits retained by LII and the captive are customary for companies of our size in our
industry and are appropriate for our business.

In addition, we use third-party insurance plans for property damage, aviation liability, directors’ and officers’
liability, and other exposures. Each of these policies may include per occurrence and annual aggregate limits.
However, we believe these limits are customary for companies of our size in our industry and are appropriate for our
business.

36

The self-insurance expense and liabilities are primarily determined based on our historical claims information,
as well as industry factors and trends. We maintain safety and manufacturing programs that are designed to improve
the safety and effectiveness of our business processes and, as a result, reduce the level and severity of our various
self-insurance risks. In recent years, our actual claims experience has been trending favorably and therefore, both
self-insurance expense and the related liability have decreased. To the extent actuarial assumptions change and
claims experience rates differ from historical rates, our liability may change. The self-insurance liabilities recorded
in Accrued Expenses in the accompanying Consolidated Balance Sheets were $61.3 million as of December 31,
2010 and $60.4 million as of December 31, 2009.

Derivative Accounting

We use futures contracts and fixed forward contracts to mitigate our exposure to volatility in commodity prices
in the ordinary course of business. Fluctuations in metal commodity prices impact the value of the derivative
instruments that we hold. When metal commodity prices rise, the fair value of our futures contracts increases and
conversely, when commodity prices fall, the fair value of our futures contracts decreases. We are required to prepare
and maintain contemporaneous documentation for futures contracts to be formally designated as cash flow hedges.
Our failure to comply with the strict documentation requirements could result in the de-designation of cash flow
hedges, which may significantly impact our consolidated financial statements.

Income Taxes

In determining income for financial statement purposes, we must make certain estimates and judgments in the
calculation of tax provisions and the resultant tax liabilities and in the recoverability of deferred tax assets that arise
from temporary differences between the tax and financial statement recognition of revenue and expense. In the
ordinary course of global business, there may be many transactions and calculations where the ultimate tax outcome
is uncertain. The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax
laws. We recognize potential liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based
on an estimate of the ultimate resolution of whether, and the extent to which, additional taxes will be due. Although
we believe the estimates are reasonable, no assurance can be given that the final outcome of these matters will not be
different than what is reflected in the historical income tax provisions and accruals.

As part of our financial reporting process, we must assess the likelihood that our deferred tax assets can be
recovered. If recovery is not likely, the provision for taxes must be increased by recording a reserve in the form of a
valuation allowance for the deferred tax assets that are estimated not to be ultimately recoverable. In this process,
certain relevant criteria are evaluated, including the existence of deferred tax liabilities that can be used to absorb
deferred tax assets, the taxable income in prior carryback years that can be used to absorb net operating losses and
credit carrybacks and taxable income in future years. Our judgment regarding future taxable income may change
due to future market conditions, changes in U.S. or international tax laws and other factors. These changes, if any,
may require material adjustments to these deferred tax assets and an accompanying reduction or increase in net
income in the period when such determinations are made. In addition to the risks to the effective tax rate described
above, the effective tax rate reflected in forward-looking statements is based on current tax law. Any significant
changes in the tax laws could affect these estimates.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining adequate internal control over financial
reporting. As defined by the Securities and Exchange Commission, internal control over financial reporting is a
process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation
of the consolidated financial statements in accordance with U.S. generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

Management, including our Chief Executive Officer and Chief Financial Officer, has undertaken an assess-
ment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2010, based
on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission. Management’s assessment included an evaluation of the design of the
Company’s internal control over financial reporting and testing of the operational effectiveness of those controls.

Based on this assessment, management concluded that as of December 31, 2010, the Company’s internal

control over financial reporting was effective.

KPMG LLP, the independent registered public accounting firm that audited the Company’s consolidated
financial statements, has issued an audit report including an opinion on the effectiveness of our internal control over
financial reporting as of December 31, 2010, a copy of which is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders
Lennox International Inc.:

We have audited the accompanying consolidated balance sheets of Lennox International Inc. and subsidiaries
(the Company) as of December 31, 2010 and 2009, and the related consolidated statements of operations,
stockholders’ equity and comprehensive income (loss), and cash flows for each of the years in the three-year
period ended December 31, 2010. In connection with our audits of the consolidated financial statements, we also
have audited the financial statement schedule. We also have audited the Company’s internal control over financial
reporting as of December 31, 2010, based on criteria established in Internal Control — Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Lennox International
Inc.’s management is responsible for these consolidated financial statements, the financial statement schedule, for
maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal
control over financial reporting, included in the accompanying Management’s Report on Internal Control Over
Financial Reporting. Our responsibility is to express an opinion on these consolidated financial statements, the
financial statement schedule and the effectiveness of the Company’s internal control over financial reporting based
on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about
whether the financial statements are free of material misstatement and whether effective internal control over
financial reporting was maintained in all material respects. Our audits of the consolidated financial statements
included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by management, and evaluating the overall
financial statement presentation. Our audit of internal control over financial reporting included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and
testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our
audits also included performing such other procedures as we considered necessary in the circumstances. We believe
that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles. A company’s internal control over financial reporting
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance
with generally accepted accounting principles, and that receipts and expenditures of the company are being made
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s
assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

39

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects,
the financial position of Lennox International Inc. and subsidiaries as of December 31, 2010 and 2009, and the
results of their operations and their cash flows for each of the years in the three-year period ended December 31,
2010, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial
statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole,
present fairly, in all material respects, the information set forth therein. Also in our opinion, Lennox International
Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010,
based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission.

LENNOX INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
For the Years Ended December 31, 2010, 2009 and 2008

1. Nature of Operations:

Lennox International Inc., a Delaware corporation, through its subsidiaries (referred to herein as “we,” “our,”
“us,” “LII” or the “Company”), is a leading global provider of climate control solutions. We design, manufacture,
market and service a broad range of products for the heating, ventilation, air conditioning and refrigeration
(“HVACR”) markets. We operate in four reportable business segments of the HVACR industry: Residential
Heating & Cooling, Commercial Heating & Cooling, Service Experts, and Refrigeration. See Note 19 for financial
information regarding our reportable segments.

We sell our products and services through a combination of distributors, independent and company-owned
dealer service centers, other installing contractors, wholesalers, manufacturers’ representatives, original equipment
manufacturers and to national accounts.

2. Summary of Significant Accounting Policies:

Principles of Consolidation

The consolidated financial statements include the accounts of Lennox International Inc. and the accounts of

our majority-owned subsidiaries. All intercompany transactions, profits and balances have been eliminated.

Cash and Cash Equivalents

We consider all highly liquid temporary investments with original maturity dates of three months or less to be
cash equivalents. Cash and cash equivalents consisted primarily of bank deposits and US Treasury money market
securities.

During the first quarter of 2010, our captive insurance subsidiary entered into an agreement in which cash was
placed into a trust for the benefit of a third-party insurance provider. The purpose of the trust is to pay workers
compensation claims for policy years 2003 — 2009 until the liabilities are fully extinguished. These policies were
written by the third-party insurance provider, and then reinsured by our captive insurance subsidiary. This
transaction was classified as restricted cash on the accompanying Consolidated Balance Sheets. The balance at
December 31, 2010 was $12.2 million.

Accounts and Notes Receivable

Accounts and notes receivable are shown in the accompanying Consolidated Balance Sheets, net of allowance
for doubtful accounts. The allowance for doubtful accounts is generally established during the period in which
receivables are recognized and is maintained at a level deemed appropriate based on historical and other factors that
affect collectability. Such factors include the historical trends of write-offs and recovery of previously written-off
accounts, the financial strength of the customer and projected economic and market conditions. We determine the
delinquency status of receivables predominantly based on contractual terms and write off uncollectible receivables
after management’s review of factors that affect collectability as noted above, among other considerations. We have
no significant concentrations of credit risk within our accounts and notes receivable.

Inventories

Inventory costs include material, labor, depreciation and plant overhead. Inventories of $123.8 million and
$100.8 million as of December 31, 2010 and 2009, respectively, were valued at the lower of cost or market using the
last-in, first-out (“LIFO”) cost method. The remaining portion of the inventory is valued at the lower of cost or
market with cost being determined either on the first-in, first-out (“FIFO”) basis or average cost. We elected to use
the LIFO cost method for our domestic manufacturing companies in 1974 and continued to elect the LIFO cost
method for new operations through the late 1980s. The types of inventory include raw materials, purchased

45

LENNOX INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

components, work-in-process, repair parts and finished goods. Starting in the late 1990s, we began adopting the
FIFO cost method for all new domestic manufacturing operations (primarily acquisitions). Our operating entities
with a previous LIFO election continue to use the LIFO cost method. We also use the FIFO cost method for all of our
foreign-based manufacturing facilities as well as our Service Experts segment, whose inventory is limited to service
parts and finished goods.

Property, Plant and Equipment

Property, plant and equipment is stated at cost, net of accumulated depreciation. Expenditures that increase the
utility or extend the useful lives of fixed assets are capitalized and expenditures for maintenance and repairs are
charged to expense as incurred. Depreciation is computed using the straight-line method over the following
estimated useful lives:

Buildings and improvements . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Machinery and equipment . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

2 to 40 years
1 to 15 years

We periodically review long-lived assets for impairment as events or changes in circumstances indicate that the
carrying amount of such assets might not be recoverable. In order to assess recoverability, we compare the estimated
expected future undiscounted cash flows identified with each long-lived asset or related asset group to the carrying
amount of such assets. If the expected future cash flows do not exceed the carrying value of the asset or assets being
reviewed, an impairment loss is recognized based on the excess of the carrying amount of the impaired assets over
their fair value.

Goodwill

Goodwill represents the excess of cost over fair value of assets of acquired businesses. Goodwill and intangible
assets determined to have an indefinite useful life are not amortized, but are instead tested for impairment at least
annually. We complete our annual goodwill impairment tests in the first quarter of each fiscal year and continuously
monitor our operations for indicators of goodwill impairment based on current market conditions.

We assign goodwill to the reporting units that benefit from the synergies of our acquisitions, which are the
reporting units that report the results of such acquisitions. If we reorganize our management structure, the related
goodwill is allocated to the affected reporting units based upon the relative fair values of those reporting units.
Assets and liabilities, including deferred income taxes, are generally directly assigned to the reporting units through
our segment reporting system as part of our financial closing process. However, certain assets and liabilities,
including information technology assets and pension, self-insurance, and environmental liabilities, are commonly
managed and are not allocated to the segments in the normal course of our financial reporting process and therefore
must be assigned to the reporting units based upon appropriate methods.

Reporting units that we test are generally equivalent to our business segments, or in some cases, one level
below. We review our reporting unit structure each year as part of our annual goodwill impairment testing and
reporting units are determined based upon a review of the periodic financial information supplied to and reviewed
by our Chief Executive Officer (the chief operating decision maker). We aggregate operating units reviewed into
reporting units when those operating units share similar economic characteristics.

We estimate reporting unit fair values using standard business valuation techniques such as discounted cash
flows and reference to comparable business transactions and observable fair values of comparable entities. The
discounted cash flow approach is the principal technique we use. We use comparable business transactions and
observable fair values of comparable entities as a reasonableness test of our principal technique as we believe that
the discounted cash flow approach provides greater detail and opportunity to reflect specific facts, circumstances
and economic conditions for each reporting unit. Comparable business transactions are often limited in number, the
information can be dated, and may require significant adjustments due to differences in the size of the business,

46

LENNOX INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

markets served, product offered, and other factors. We therefore believe that in our circumstances, this makes
comparisons to comparable business transactions less reliable than the discounted cash flows method.

The discounted cash flows used to estimate fair value are based on assumptions regarding each reporting unit’s
estimated projected future cash flows and the estimated weighted-average cost of capital that a market participant
would use in evaluating the reporting unit in a purchase transaction. The estimated weighted-average cost of capital
is based on the risk-free interest rate and other factors such as equity risk premiums and the ratio of total debt to
equity capital. In performing these impairment tests, we take steps to ensure that appropriate and reasonable cash
flow projections and assumptions are used. We reconcile our estimated enterprise value to our market capitalization
and determine the reasonableness of the cost of capital used by comparing to market data. We also perform
sensitivity analyses on the key assumptions used, such as the weighted-average cost of capital and terminal growth
rates.

We also monitor economic, legal, regulatory and other factors for LII as a whole and for each reporting unit
between annual impairment tests to ensure that there are no indicators that make it more likely than not that there
has been a decline in the fair value of any reporting unit below its carrying value. Specifically, we monitor industry
trends, our market capitalization, recent and forecasted financial performance of our reporting units, and the timing
and nature of our restructuring activities. While our recent financial performance is below historical levels, we
determined that no impairment of our goodwill existed as of December 31, 2010, 2009 or 2008. If these estimates or
the related assumptions change, we may be required to record non-cash impairment charges for these assets in the
future. For additional disclosures on goodwill, see Note 5.

Intangible and Other Assets

We amortize intangible assets with finite lives over their respective estimated useful lives to their estimated

residual values.

Identifiable intangible and other assets that have finite lives are amortized over their estimated useful lives as

follows:

Asset

Deferred financing costs
Customer relationships

Useful Life

Effective interest method
Straight-line method up to 10 years

We periodically review intangible assets with estimable useful lives for impairment as events or changes in
circumstances indicate that the carrying amount of such assets might not be recoverable. In order to assess
recoverability, we compare the estimated expected undiscounted future cash flows identified with each intangible
asset or related asset group to the carrying amount of such assets. If the expected future cash flows do not exceed the
carrying value of the asset or assets being reviewed, an impairment loss is recognized based on the excess of the
carrying amount of the impaired assets over their fair value.

In assessing the fair value of our other intangibles, we must make assumptions that a market participant would
make regarding estimated future cash flows and other factors to determine the fair value of the respective assets. If
these estimates or the related assumptions change, we may be required to record impairment charges for these assets
in the future.

Product Warranties

For some of our heating, ventilation and air conditioning (“HVAC”) products, we provide warranty terms
ranging from one to 20 years to customers for certain components such as compressors or heat exchangers. For
select products, we also provide lifetime warranties for heat exchangers. A liability for estimated warranty expense
is recorded on the date that revenue is recognized. Our estimates of future warranty costs are determined for each
product line. The number of units that we expect to repair or replace is determined by applying the estimated failure

47

LENNOX INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

rate, which is generally based on historical experience, to the number of units that have been sold and are still under
warranty. The estimated units to be repaired under warranty are multiplied by the average cost to repair or replace
such products to determine the estimated future warranty cost. We do not discount product warranty liabilities as the
amounts are not fixed and the timing of future cash payments is neither fixed nor reliably determinable. We also
provide for specifically identified warranty obligations. Estimated future warranty costs are subject to adjustment
from time to time depending on changes in actual failure rate and cost experience. Subsequent costs incurred for
warranty claims serve to reduce the accrued product warranty liability.

Pensions and Postretirement Benefits

We provide pension and postretirement medical benefits to eligible domestic and foreign employees and
recognize pension and postretirement benefit costs over the estimated service life or average life expectancy of
those employees. We also recognize the funded status of our benefit plans, as measured at year-end by the difference
between plan assets at fair value and the benefit obligation, in the Consolidated Balance Sheets. Changes in the
funded status are recognized in the year in which the changes occur through accumulated other comprehensive
income (“AOCI”). Actuarial gains or losses are amortized into net period benefit cost over the estimated service life
of covered employees or average life expectancy of participants depending on the plan.

The benefit plan assets and liabilities reflect assumptions about the long-range performance of our benefit
plans. Should actual results differ from management’s estimates, revisions to the benefit plan assets and liabilities
would be required. For additional disclosures on pension and postretirement medical benefits, including how we
determine the assumptions used, see Note 12.

Self-Insurance

Self-insurance expense and liabilities, calculated on an undiscounted basis, are actuarially determined based
primarily on our historical claims information, as well as industry factors and trends. As of December 31, 2010, self-
insurance and captive reserves represent the best estimate of the future payments to be made on losses reported and
unreported for 2010 and prior years. The majority of our self-insured risks (excluding auto liability and physical
damage) will be paid over an extended period of time.

Actual payments for claims reserved as of December 31, 2010 may vary depending on various factors,
including the development and ultimate settlement of reported and unreported claims. To the extent actuarial
assumptions change and claims experience rates differ from historical rates, our liability may change. For additional
disclosures on self-insured risks and reserves, see Note 10.

Derivatives

We use futures contracts and fixed forward contracts to mitigate the exposure to volatility in commodity prices
and foreign exchange rates, and we use an interest rate swap to hedge changes in the benchmark interest rate related
to our revolving credit facility. We hedge only exposures in the ordinary course of business and do not hold or trade
derivatives for profit. All derivatives are recognized in the Consolidated Balance Sheets at fair value. Classification
of each hedging instrument is based upon whether the maturity of the instrument is less than or greater than
12 months. For more information, see Note 8.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are
recognized for the future tax consequences attributable to differences between the financial statement carrying
amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry
forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be recovered or settled. The effect of a

48

LENNOX INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the
enactment date.

Unrecognized tax benefits are accounted for as required by the Financial Accounting Standards Board

(“FASB”) Accounting Standards Codification (“ASC”) Topic 740. For more information, see Note 9.

Revenue Recognition

Our Residential Heating & Cooling, Commercial Heating & Cooling and Refrigeration segments’ revenue
recognition practices depend upon the shipping terms for each transaction. Shipping terms are primarily FOB
Shipping Point and, therefore, revenues are recognized for these transactions when products are shipped to
customers and title passes. However, certain customers in our smaller operations, primarily outside of North
America, have shipping terms where title and risk of ownership do not transfer until the product is delivered to the
customer. For these transactions, revenues are recognized on the date that the product is received and accepted by
such customers. We have experienced returns for miscellaneous reasons and we record a reserve for these returns
based on historical experience at the time we recognize revenue. Our historical rate of returns are insignificant as a
percentage of sales.

Our Service Experts segment recognizes sales, installation, maintenance and repair revenues at the time the
services are completed. The Service Experts segment also provides HVAC system design and installation services
under fixed-price contracts, which may extend up to one year. Revenue for these services is recognized using the
percentage-of-completion method, based on the percentage of incurred contract costs-to-date in relation to total
estimated contract costs, after giving effect to the most recent estimates of total cost. The effect of changes to total
estimated contract revenue or cost is recognized in the period such changes are determined. Provisions for estimated
losses on individual contracts are made in the first period in which the loss becomes probable.

We engage in cooperative advertising, customer rebate, cash discount and other miscellaneous programs that
result in payments or credits being issued to our customers. Our policy is to record the discounts and incentives as a
reduction of sales when the sales are recorded, with the exception of certain cooperative advertising expenditures
that are charged to Selling, General and Administrative (“SG&A”) Expenses. Under these cooperative advertising
programs, we receive, or will receive, an identifiable benefit (goods or services) in exchange for the consideration
given.

Cost of Goods Sold

The principal components of cost of goods sold in our manufacturing operations are component costs, raw
materials, factory overhead, labor, estimated costs of warranty expense, and freight and distribution costs. In our
Service Experts segment, the principal components of cost of goods sold are equipment, vehicle costs, parts and
supplies, and labor.

Selling, General and Administrative Expenses

SG&A expenses include all other payroll and benefit costs, advertising, commissions, research and devel-
opment, information technology costs, and other selling, general and administrative related costs such as insurance,
travel, non-production depreciation and rent.

Stock-Based Compensation

We recognize compensation expense for stock-based arrangements over the required employee service
periods. We base stock-based compensation costs on the estimated grant-date fair value of the stock-based awards
that are expected to ultimately vest and adjust expected vesting rates to actual rates as additional information
becomes known. We also adjust performance achievement rates based on our best estimates of those rates at the end
of the performance period.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Translation of Foreign Currencies

All assets and liabilities of foreign subsidiaries and joint ventures are translated into U.S. dollars using rates of
exchange in effect at the balance sheet date. Revenues and expenses are translated at weighted average exchange
rates during the year. The unrealized translation gains and losses are included in AOCI in the accompanying
Consolidated Balance Sheets. Transaction gains and losses are included in Losses (Gains) and Other Expenses, net
in the accompanying Consolidated Statements of Operations.

Use of Estimates

The preparation of financial statements requires us to make estimates and assumptions about future events.
These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures
about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the
valuation of accounts receivable, inventories, goodwill, intangible assets, and other long-lived assets, contingen-
cies, guarantee obligations, indemnifications, and assumptions used in the calculation of income taxes, pension and
postretirement medical benefits, among others. These estimates and assumptions are based on our best estimates
and judgment.

We evaluate our estimates and assumptions on an ongoing basis using historical experience and other factors,
including the current economic environment. We believe these estimates and assumptions to be reasonable under
the circumstances and adjust such estimates and assumptions when facts and circumstances dictate. Volatile equity,
foreign currency, and commodity markets, have combined to increase the uncertainty inherent in such estimates and
assumptions. As future events and their effects cannot be determined with precision, actual results could differ
significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic
environment will be reflected in the financial statements in future periods.

Reclassifications

Certain amounts have been reclassified from the prior year presentation to conform to the current year

presentation.

Joint Ventures and Other Equity Investment:

Joint Ventures

We participate in two joint ventures; the largest is located in the U.S. and the other in Mexico. These joint
ventures are engaged in the manufacture and sale of compressors, unit coolers and condensing units. Because we
exert significant influence over these affiliates based upon our respective 25% and 50% ownership, but do not
control them due to venture partner participation, they have been accounted for under the equity method and their
financial position and results of operations are not consolidated. We purchase compressors from our U.S. joint
venture for use in certain of our products.

During 2008, the Company loaned $1.6 million to its joint venture in Mexico due to that entity’s cash needs
related to margin calls on forward commodity contracts and operating cash requirements. The joint venture partner
loaned equal amounts under identical terms to the joint venture; and therefore, the investment continues to be
recorded under the equity method. As of December 31, 2010 and 2009, the outstanding loan balance was
$0.9 million and $1.6 million, respectively.

Other Investment

LII also has an investment in a compressor manufacturer located in Thailand. During 2008, under the equity
method we recorded investment losses of $0.3 million and dividends of $1.1 million as reductions to the investment
balance. We also recorded $9.1 million of impairment charges related to this investment in 2008.

Also, as a result of a rights offering in 2008, our percentage of equity ownership declined from 13% to 9%.
While formerly accounted for under the equity method, the investment of $18.0 million in 2010 and $5.4 million in
2009 was accounted for as an available-for-sale marketable equity security. A net gain of $12.5 million in 2010 was
recorded in AOCI. The fair value of the investment was measured based upon the quoted market price of the
investee’s common stock as listed on the Stock Exchange of Thailand, multiplied by the number of shares owned.

8. Derivatives:

General

Our earnings and cash flows are subject to fluctuations due to changes in commodity prices, interest rates, and
foreign currency exchange rates, and we seek to mitigate a portion of these risks by entering into derivative
contracts. The derivatives we use are commodity futures contracts, interest rate swaps, and currency forward
contracts. We do not use derivatives for speculative purposes.

The derivatives we enter into may be, but are not always, accounted for as hedges. To qualify for hedge
accounting, the derivatives must be highly effective in reducing the risk exposure that they are designed to hedge,
and it must be probable that the underlying transaction will occur. For instruments designated as cash flow hedges,
we must formally document, at inception, the relationship between the derivative and the hedged item, the risk
management objective, the hedging strategy for use of the hedged instrument, and how hedge effectiveness is, and
will be, assessed. This documentation also includes linking the derivatives that are designated as cash flow hedges to
forecasted transactions. We assess hedge effectiveness at inception and at least quarterly throughout the hedge
designation period.

We recognize all derivatives as either assets or liabilities at fair value in the Consolidated Balance Sheets,
regardless of whether or not hedge accounting is applied. For more information on the fair value of these derivative
instruments, see Note 20. We report cash flows arising from our hedging instruments consistent with the
classification of cash flows from the underlying hedged items. Accordingly, cash flows associated with our
derivative programs are classified as operating activities in the accompanying Consolidated Statements of Cash
Flows.

We monitor our derivative positions and credit ratings of our counterparties and do not anticipate losses due to

counterparty non-performance.

Hedge Accounting

The derivatives that we use as hedges of commodity prices and movements in interest rates are accounted for as
cash flow hedges. The effective portion of the gain or loss on the derivatives accounted for as hedges is recorded, net
of applicable taxes, in AOCI, a component of Stockholders’ Equity in the accompanying Consolidated Balance
Sheets. When earnings are affected by the variability of the underlying cash flow, the applicable offsetting amount
of the gain or loss from the derivatives that is deferred in AOCI is reclassified into earnings in the same financial
statement line item that the hedged item is recorded in. Ineffectiveness, if any, is recorded in earnings each period. If
the hedging relationship ceases to be highly effective, the net gain or loss shall remain in AOCI and will be
reclassified into earnings when earnings are affected by the variability of the underlying cash flow. If it becomes
probable that the forecasted transaction will not occur by the end of the originally specified period or within two
months thereafter, the net gain or loss remaining in AOCI will be reclassified to earnings immediately.

Accounting for Derivatives When Hedge Accounting is Not Applied

We may also enter into derivatives that economically hedge certain of our risks, even though hedge accounting
does not apply or we elect not to apply hedge accounting to these instruments. The changes in fair value of the
derivatives act as an economic offset to changes in the fair value of the underlying items. Changes in the fair value of
instruments not designated as cash flow hedges are recorded in earnings throughout the term of the derivative
instrument and are reported in Losses (Gains) and Other Expenses, net in the accompanying Consolidated
Statements of Operations.

Objectives and Strategies for Using Derivative Instruments

Commodity Price Risk

We utilize a cash flow hedging program to mitigate our exposure to volatility in the prices of metal
commodities we use in our production processes. The hedging program includes the use of futures contracts,
and we enter into these contracts based on our hedging strategy. We use a dollar cost averaging strategy for our
hedge program. As part of this strategy, a higher percentage of commodity price exposures are hedged near term
with lower percentages hedged at future dates. This strategy provides us with protection against near-term price
volatility caused by market speculators and market forces, such as supply variation, while allowing us to adjust to
market price movements over time. Upon entering into futures contracts, we lock in prices and are subject to
derivative losses should the metal commodity prices decrease and gains should the prices increase.

Interest Rate Risk

A portion of our debt bears interest at variable interest rates and therefore, we are subject to variability in the
cash paid for interest expense. In order to mitigate a portion of this risk, we use a hedging strategy to eliminate the
variability of cash flows in the interest payments associated with the first $100 million of the total variable-rate debt
outstanding under our revolving credit facility that is solely due to changes in the benchmark interest rate. This
strategy allows us to fix a portion of our interest payments.

On June 12, 2009, we entered into a $100 million pay-fixed, receive-variable interest rate swap with a large
financial institution at a fixed interest rate of 2.66%. The variable portion of the interest rate swap is tied to the
1-Month LIBOR (the benchmark interest rate). The interest rates under both the interest rate swap and the
underlying debt are reset, the swap is settled with the counterparty, and interest is paid, on a monthly basis. The
interest rate swap expires October 12, 2012. We account for the interest rate swap as a cash flow hedge.

Foreign Currency Risk

Foreign currency exchange rate movements create a degree of risk by affecting the U.S. dollar value of assets
and liabilities arising in foreign currencies. Our objective for entering into foreign currency forward contracts is to
mitigate the impact of short-term currency exchange rate movements on certain short-term intercompany trans-
actions. In order to meet that objective, we periodically enter into foreign currency forward contracts that act as
economic hedges against changes in foreign currency exchange rates. These forward contracts are not designated as
hedges and generally expire during the quarter that we entered into them.

Cash Flow Hedges

We include (gains) losses in AOCI in connection with our commodity cash flow hedges. The (gains) losses
related to commodity price hedges are expected to be reclassified into earnings within the next 18 months based on
the prices of the commodities at settlement date. Assuming that commodity prices remain constant, $10.9 million of
derivative gains are expected to be reclassified into earnings within the next 12 months. Commodity futures
contracts that are designated as cash flow hedges and are in place as of December 31, 2010 are scheduled to mature
through May 2012.

The (gains) losses related to our interest rate swap are expected to be reclassified into earnings within the next
22 months based on the term of the swap. Assuming that the benchmark interest rate remains constant, $1.4 million
of derivative losses are expected to be reclassified into earnings within the next 12 months.

Deferred income taxes reflect the tax consequences on future years of temporary differences between the tax
basis of assets and liabilities and their financial reporting basis and are reflected as current or non-current depending
on the classification of the asset or liability generating the deferred tax. The deferred tax provision for the periods
shown represents the effect of changes in the amounts of temporary differences during those periods.

As of December 31, 2010 and 2009, we had $6.5 million and $9.6 million in tax effected state net operating
loss carryforwards, respectively, and $35.8 million and $38.7 million in tax effected foreign net operating loss
carryforwards, respectively. The state and foreign net operating loss carryforwards begin expiring in 2011. The
deferred tax asset valuation allowance relates primarily to the operating loss carryforwards in various states in the
U.S., European and Asian tax jurisdictions. The decrease in the valuation allowance is primarily the result of foreign
and state losses which were not previously benefited and currency fluctuation.

In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some
portion or all of the deferred tax assets will not be realized. We consider the reversal of existing taxable temporary
differences, projected future taxable income, and tax planning strategies in making this assessment. Based upon the
level of historical taxable income and projections for future taxable income over the periods in which the deferred
tax assets are deductible, we believe it is more likely than not that we will realize the benefits of these deductible
differences, net of the existing valuation allowances, as of December 31, 2010.

In order to realize the net deferred tax asset, we will need to generate future foreign taxable income of
approximately $98.5 million during the periods in which those temporary differences become deductible. We also
will need to generate U.S. federal income of approximately $46.8 million in addition to our carryback capacity to
fully realize the federal deferred tax asset. U.S. taxable income for the years ended December 31, 2010 and 2009
was $150.5 million and $36.7 million, respectively.

A limited provision has been made for income taxes which may become payable upon distribution of our
foreign subsidiaries’ earnings related to the Czech Republic. It is not practicable to estimate the amount of tax that

might be payable with regard to any other distribution of foreign subsidiary earnings because our intent is to
permanently reinvest these earnings or to repatriate earnings when it is tax effective to do so.

Included in the balance of unrecognized tax benefits as of December 31, 2010 are potential benefits of
$0.7 million that, if recognized, would affect the effective tax rate on income from continuing operations. As of
December 31, 2010, we had recognized $0.1 million (net of federal tax benefits) in interest and penalties in income
tax expense.

The Internal Revenue Service (“IRS”) completed its examination of our consolidated tax returns for the years
1999 — 2003 and issued a Revenue Agent’s Report (“RAR”) on April 6, 2006. We reached a settlement with the IRS
in December 2008 that resulted in an immaterial impact to the Consolidated Statements of Operations.

The IRS completed its examination of our consolidated tax returns for the years 2004-2005 and issued an RAR

impact to the Consolidated Statements of Operations.

The IRS completed its examination of our consolidated tax returns for the years 2006-2007 and issued an RAR
on June 1, 2009. We reached a settlement with the IRS in the third quarter of 2009 that resulted in an immaterial
impact to the Consolidated Statements of Operations.

We are currently under examination for our U.S. federal income taxes for 2008, 2009 and 2010. We are subject
to examination by numerous other taxing authorities in jurisdictions such as Australia, Belgium, France, Canada,
and Germany. We are generally no longer subject to U.S. federal, state and local, or non-U.S. income tax
examinations by taxing authorities for years before 2004.

During 2010, numerous states, including Colorado, Maine, Utah, the District of Columbia, California and
Connecticut, enacted legislation effective for tax years beginning on or after January 1, 2010, including require-
ments for combined reporting, changes to apportionment methods and changes to nexus requirements. We
determined the impact of these changes to be immaterial.

On June 22, 2006, we entered into an agreement with a financial institution to lease our corporate headquarters
in Richardson, Texas for a term of seven years (the “Lake Park Lease”). The leased property consists of an office
building of approximately 192,000 square feet, land and related improvements. During the term, the Lake Park
Lease requires us to pay base rent in quarterly installments, payable in arrears. At the end of the term, we must do
one of the following: (i) purchase the property for approximately $41.2 million; (ii) make a final payment under the
lease equal to approximately 82% of the Lease Balance and return the property to the financial institution in good
condition; (iii) arrange for the sale of the leased property to a third party; or (iv) renew the lease under mutually
agreeable terms. If we elect to sell the property to a third party and the sales proceeds are less than the Lease
Balance, we must pay any such deficit to the financial institution. Any such payment cannot exceed 82% of the
Lease Balance.

Our obligations under the Lake Park Lease are secured by a pledge of our interest in the leased property and are
also guaranteed by us and certain of our subsidiaries. The Lake Park Lease, as amended, contains restrictive
covenants that are consistent with those of our revolving credit facility. We were in compliance with these financial
covenants as of December 31, 2010. The Lake Park Lease is accounted for as an operating lease.

Environmental

Applicable environmental laws can potentially impose obligations to remediate hazardous substances at our
properties, at properties formerly owned or operated by us and at facilities to which we have sent or send waste for
treatment or disposal. We are aware of contamination at some facilities; however, we do not presently believe that
any future remediation costs at such facilities will be material to our results of operations.

The amount and timing of cash payments are reliably determinable and, therefore, we have recorded

environmental reserves at their present values.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

At the end of each accounting period, we evaluate our warranty liabilities and during the second quarter of each
year, we perform a complete reevaluation of our HVAC warranty liabilities. As a result of our annual evaluation, we
recorded a reduction in warranty liabilities in the second quarter of 2010 that is the principal amount contained
within the changes in estimates associated with pre-existing liabilities of $6.2 million above.

We incur the risk of liability claims for the installation and service of heating and air conditioning products,
and we maintain liabilities for those claims that we self-insure. We are involved in various claims and lawsuits
related to our products. Our product liability insurance policies have limits that, if exceeded, may result in
substantial costs that could have an adverse effect on our results of operations. In addition, warranty claims are not
covered by our product liability insurance and certain product liability claims may also not be covered by our
product liability insurance. There have been no material changes in the circumstances since our latest fiscal year-
end.

We also may incur costs related to our products that may not be covered under our warranties and are not
covered by insurance, and we may, from time to time, repair or replace installed products experiencing quality
issues in order to satisfy our customers and to protect our brand. These product quality issues may be caused by
vendor-supplied components that fail to meet required specifications.

We have identified a product quality issue in a heating and cooling product line produced in 2006 and 2007 that
we believe results from a vendor-supplied materials quality issue. We have recorded an expense of $24.4 million in
2009 for the portion of the issue that was probable and reasonably estimable. There were no material charges
recorded in 2010. As of December 31, 2010 and 2009, $16.0 million and $21.6 million, respectively, was accrued
for this matter. We may incur additional charges in the future as more information becomes available. The expense
for this product quality issue, and the related liability, has not been included in the tables related to our estimated
warranty liabilities. The expense related to this product quality issue was classified in Cost of Goods Sold in the
Consolidated Statements of Operations and the related liability is included in Accrued Expenses in the accom-
panying Consolidated Balance Sheets.

Self Insurance

We use a combination of third-party insurance and self-insurance plans (large deductible or captive) to provide
protection against claims relating to workers’ compensation/employers’ liability, general liability, product liability,
auto liability, auto physical damage and other exposures. Prior to the third quarter of 2009, these policies were
written by a third-party insurance provider, which was then reinsured by our captive insurance subsidiary. Starting
with the third quarter of 2009, we use large deductible insurance plans for workers’ compensation/employers’
liability, general liability, product liability, and auto liability. These policies are written through third-party
insurance providers. We also carry umbrella or excess liability insurance for all third-party and self-insurance
plans, except for directors’ and officers’ liability, property damage and various other insurance programs. We
believe the limit within our excess policy is adequate for companies of our size in our industry. We believe that the
deductibles and liability limits retained by LII and the captive are customary for companies of our size in our
industry and are appropriate for our business.

In addition, we use third-party insurance plans for property damage, aviation liability, directors’ and officers’
liability, and other exposures. Each of these policies may include per occurrence and annual aggregate limits.
However, we believe these limits are customary for companies of our size in our industry and are appropriate for our
business.

We maintain safety and manufacturing programs that are designed to improve the safety and effectiveness of
our business processes and, as a result, reduce the level and severity of our various self-insurance risks. In recent
years, our actual claims experience has been trending favorably and therefore, both self-insurance expense and the
related liability have decreased.

64

LENNOX INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Since we have a captive insurance company, we are required to maintain specified levels of liquid assets from
which we must pay claims. The majority of our self-insured risks (excluding auto liability and physical damage)
will be paid over an extended period of time. To the extent actuarial assumptions change and claims experience rates
differ from historical rates, our liability may change.

The self-insurance liabilities recorded in Accrued Expenses in the accompanying Consolidated Balance Sheets

were $61.3 million and $60.4 million as of December 31, 2010 and 2009, respectively.

Litigation

We are involved in a number of claims and lawsuits incident to the operation of our businesses. Insurance
coverages are maintained and estimated costs are recorded for such claims and lawsuits. It is management’s opinion
that none of these claims or lawsuits will have a material adverse effect on our financial position, results of
operations or cash flows. Costs related to such matters were not material to the periods presented.

We estimate the costs to settle pending litigation based on experience involving similar claims and specific
facts known. We do not believe that any current or pending or threatened litigation will have a material adverse
effect on our financial position. Litigation and arbitration, however, involve uncertainties and it is possible that the
eventual outcome of litigation could adversely affect our results of operations for a particular period.

entered into a binding Memorandum of Understanding (“MOU”) and have reached tentative terms for settlement of
the case. At the parties’ request, the court stayed the lawsuit shortly after the MOU was signed. On January 11, 2011,
the court granted preliminary approval of the settlement. The court set June 2, 2011 as the date for the final approval
hearing. Total charges related to this matter recorded in 2010 were $9.3 million. These charges are included in
Selling, General and Administrative Expenses and Losses (Gains) and Other Expenses, Net in the accompanying

As of December 31, 2010, we had outstanding borrowings of $100.0 million under our $650.0 million
domestic revolving credit facility and $69.5 million was committed to standby letters of credit. The remaining
$480.5 million was available for future borrowings subject to covenant limitations. The facility matures in October
2012. As of December 31, 2010, we were in compliance with all covenant requirements.

We have additional borrowing capacity through several of our foreign subsidiaries used primarily to finance
seasonal borrowing needs. We had $1.4 million and $2.5 million of obligations outstanding through our foreign
subsidiaries as of December 31, 2010 and 2009, respectively. Available borrowing capacity at December 31, 2010
and 2009, under foreign facilities was $10.1 million and $12.6 million, respectively.

Our domestic revolving credit facility includes a subfacility for swingline loans of up to $50.0 million and
provides for the issuance of letters of credit for the full amount available under the domestic revolving credit facility.
Our weighted average borrowing rate on the domestic revolving credit facility was 0.96% and 0.84% as of
December 31, 2010 and 2009, respectively.

Our domestic revolving credit facility contains financial covenants relating to leverage and interest coverage.
Other covenants contained in our domestic revolving credit facility restrict, among other things, mergers, asset
dispositions, guarantees, debt, liens, acquisitions, investments, affiliate transactions and our ability to make
restricted payments. The financial covenants require us to maintain defined levels of Consolidated Indebtedness
to Adjusted EBITDA Ratio and a Cash Flow (defined as EBITDA minus capital expenditures) to Net Interest
Expense Ratio. The required ratios as of December 31, 2010 are detailed below:

Consolidated Indebtedness to Adjusted EBITDA Ratio not greater than . . . . . . . . . . . . . . . 3.5 : 1.0
Cash Flow to Net Interest Expense Ratio no less than . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.0 : 1.0

Our domestic revolving credit facility contains customary events of default. These events of default include
nonpayment of principal or interest, breach of covenants or other restrictions or requirements, default on any other

66

LENNOX INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

indebtedness or receivables securitizations (cross default), and bankruptcy. A cross default under our revolving
credit facility could occur if:

(cid:129) we fail to pay any principal or interest when due on any other indebtedness or receivables securitization of at

least $40.0 million; or

(cid:129) we are in default in the performance of, or compliance with any term of any other indebtedness or receivables
securitization in an aggregate principal amount of at least $40.0 million, or any other condition exists which
would give the holders the right to declare such indebtedness due and payable prior to its stated maturity.

Each of our major debt agreements contains provisions by which a default under one agreement causes a
default in the others (a cross default). If a cross default under the revolving credit facility, our senior unsecured
notes, or our revolving period asset securitization program were to occur, it could have a wider impact on our
liquidity than might otherwise occur from a default of a single debt instrument or lease commitment.

If any event of default occurs and is continuing, lenders with a majority of the aggregate commitments may
require the administrative agent to terminate our right to borrow under our domestic revolving credit facility and
accelerate amounts due under our domestic revolving credit facility (except for a bankruptcy event of default, in
which case such amounts will automatically become due and payable and the lenders’ commitments will
automatically terminate).

On May 6, 2010, we issued $200.0 million of senior unsecured notes due May 15, 2017 bearing fixed interest at
4.90% as a result of a public offering of securities. We received proceeds of $199.8 million from the offering for a
yield of 4.91%. We also paid and capitalized $1.9 million of debt issue costs related to the issuance. We pay interest
on the notes semiannually on May 15 and November 15.

The notes are guaranteed, on a senior unsecured basis, by each of our domestic subsidiaries that guarantee
payment by us of any indebtedness under our domestic revolving credit facility. The indenture governing the notes
contains covenants that, among other things, limit our ability and the ability of the subsidiary guarantors to: create or
incur certain liens; enter into certain sale and leaseback transactions; enter into certain mergers, consolidations and
transfers of substantially all of our assets; and transfer certain properties. The indenture also contains a cross default
provision which is triggered if we default on other debt of at least $75 million in principal which is then accelerated,
and such acceleration is not rescinded within 30 days of the notice date.

During 2008, we expanded our Tifton, Georgia manufacturing facility using the proceeds from Industrial
Development Bonds (“IDBs”). We entered into a lease agreement with the owner of the property and the issuer of
the IDBs, and through our lease payments fund the interest payments to investors in the IDBs. We also guaranteed
the repayment of the IDBs and entered into letters of credit totaling $15.5 million to fund a potential repurchase of
the IDBs in the event that investors exercised their right to tender the IDBs to the Trustee. As of December 31, 2010
and 2009, we recorded both a capital lease asset and a corresponding long-term obligation of $14.3 million related
to these transactions.

Credit Rating

At December 31, 2010, our senior credit rating was Baa3, with a stable outlook, by Moody’s and BBB-, with a

stable outlook, by Standard & Poor’s Rating Group (“S&P”).

Asset Securitization

Under a revolving period asset securitization arrangement (“ASA”), we are eligible to sell beneficial interests
in a portion of our trade accounts receivable to participating financial institutions for cash. The current arrangement
expires November 18, 2011 and is subject to renewal and contains a provision whereby we retain the right to
repurchase all of the outstanding beneficial interests transferred. Our continued involvement in the transferred
assets includes servicing, collection and administration of the transferred beneficial interests.

67

LENNOX INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The accounts receivable sold under the ASA are high quality domestic customer accounts that have not aged
significantly and the program takes into account an allowance for uncollectable accounts. The receivables
represented by the retained interest that we service are exposed to the risk of loss for any uncollectible amounts
in the pool of receivables sold under the ASA. The fair values assigned to the retained and transferred interests are
based on the sold accounts receivable carrying value given the short term to maturity and low credit risk.

The ASA contains certain restrictive covenants relating to the quality of our accounts receivable and cross-
default provisions with our Credit Agreement. The administrative agent under the ASA is also a participant in our
Credit Agreement. The participating financial institution has an investment grade credit rating. We continue to
evaluate its credit rating and have no reason to believe it will not perform under the ASA. As of December 31, 2010,
we were in compliance with all covenant requirements.

The ASA provides for a maximum securitization amount of $100.0 million or 100% of the net pool balance as
defined by the ASA. However, eligibility for securitization is limited based on the amount and quality of the
qualifying accounts receivable and is calculated monthly. The beneficial interest sold cannot exceed the maximum
amount even if our qualifying accounts receivable is greater than the maximum amount at any point in time. The
eligible amounts available were as follows (in millions):

Under the ASA, we pay certain discount fees to use the program and have the facility available to us. These
fees relate to both the used and unused portions of the securitization. The used fee is based on the beneficial interest
sold and calculated on the average floating commercial paper rate determined by the purchaser of the beneficial
interest, plus a program fee of 0.75%. The rate as of December 31, 2010 and 2009 was 1.06% and 1.38%,
respectively. The unused fee is based on 102% of the maximum available amount less the beneficial interest sold
and calculated at 0.375% fixed rate throughout the term of the agreement. We recorded these fees in Selling,
General and Administrative Expenses in the accompanying Consolidated Statements of Operations. The amounts
recorded were as follows (in millions):

Pension and Postretirement Benefit Plans

We provide pension and postretirement medical benefits to eligible domestic and foreign employees. In the
third quarter of 2008, we announced that we were freezing our defined benefit pension and profit sharing plans for
our domestic and Canadian salaried employees and moving to an enhanced defined contribution plan in 2009 for
our domestic salaried employees and 2010 for our Canadian salaried employees. We also maintain an unfunded
postretirement benefit plan, which provides certain medical and life insurance benefits to eligible employees. In
2006, we amended the postretirement benefit plan to (i) eliminate post-65 coverage for current and future nonunion
retirees and (ii) gradually shift the pre-65 medical coverage cost from us to participants starting in 2007 such that by
2010, pre-65 retirees would be paying 100% of the cost. As a result of this amendment, the postretirement plan will
still exist in 2010 and eligible nonunion participants will still be able to receive group coverage rates. However, we
will no longer be paying any portion of the participants’ premiums.

To develop the expected long-term rate of return on assets assumption for the U.S. plans, we considered the
historical returns and the future expectations for returns for each asset category, as well as the target asset allocation
of the pension portfolio and the effect of periodic rebalancing. These results were adjusted for the payment of
reasonable expenses of the plan from plan assets. This resulted in the selection of the 8.00% long-term rate of return
on assets assumption. A similar process was followed for the non-U.S.-based plans.

To select a discount rate for the purpose of valuing the plan obligations for the U.S. plans, we performed an
analysis in which the duration of projected cash flows from defined benefit and retiree healthcare plans were
matched with a yield curve based on the appropriate universe of high-quality corporate bonds that were available.
We used the results of the yield curve analysis to select the discount rate that matched the duration and payment
stream of the benefits in each plan. This resulted in the selection of the 5.47% discount rate assumption for the
U.S. qualified pension plans, 5.28% for the U.S. non-qualified pension plans, and 5.30% for the other benefits. A

We believe that by adequately diversifying the plan assets, asset returns can be optimized at an acceptable level
of risk. Since equity securities have historically generated higher returns than fixed income securities and the plan is
not fully funded, we believe it is appropriate to allocate more assets to equities than fixed income securities. In
addition, these categories are further diversified among various asset classes including high yield and emerging
markets debt, and international and emerging markets equities in order to avoid significant concentrations of risk.
Our U.S. pension plan represents approximately 90%, our Canadian pension plan approximately 6%, and our
United Kingdom (“U.K.”) pension plan approximately 4% of the total fair value of our plan assets as of
December 31, 2010.

Our U.S. pension plans’ weighted-average asset allocations as of December 31, 2010 and 2009, by asset

Our Canadian pension plan is invested in only one asset, which is a balanced fund that maintains diversification
among various asset classes, including Canadian common stocks, bonds and money market securities, U.S. equities,
other international equities and fixed income investments. Our U.K. pension plan was invested in a broad mix of
assets consisting of U.K., U.S. and international equities, U.K. fixed income securities, including corporate and
government bonds, and bank deposits.

The majority of our commingled pool /collective trust, mutual funds and balanced pension trusts are managed
by professional investment advisors. The NAVs per share are furnished in monthly and/or quarterly statements
received from the investment advisors and reflect valuations based upon their pricing policies. We have assessed the
classification of the inputs used to value these investments at Level 1 for mutual funds and Level 2 for commingled
pool / collective trusts and balance pension trusts through examination of their pricing policies and the related
controls and procedures. The fair values we report are based on the pool or trust’s NAV per share. The NAV’s per
share are calculated periodically (daily or no less than one time per month) as the aggregate value of each pool or
trust’s underlying assets divided by the number of units owned.

See Note 20 for information about our fair value hierarchies and valuation techniques.

Incentive Plan

Under the Lennox International Inc. 2010 Incentive Plan, as amended and restated (the “2010 Incentive Plan”),
we are authorized to issue awards for 24,254,706 shares of common stock. As of December 31, 2010, awards for
20,478,607 shares of common stock had been granted, net of cancellations and repurchases. Consequently, as of
December 31, 2010, there were 3,776,099 shares available for future issuance.

The 2010 Incentive Plan provides for various long-term incentive awards, which include stock options,
performance share units, restricted stock units and stock appreciation rights. A description of these long-term
incentive awards and related activity within each award category is provided below.

Performance Share Units

Total compensation expense for performance share units was $4.1 million, $1.8 million and $3.4 million for
the years ended December 31, 2010, 2009 and 2008, respectively. The weighted-average fair value of performance
share units granted during the years ended December 31, 2010, 2009 and 2008 was $44.85, $35.26 and $26.83 per
share, respectively.

Under the 2010 Incentive Plan, performance share units are granted to certain employees at the discretion of
the Board of Directors with a three-year performance period beginning January 1st of each year. Upon meeting the
performance and vesting criteria, performance share units are converted to an equal number of shares of our
common stock. Outstanding awards granted prior to 2003 vest after ten years of service at the target amount.

Performance share units vest if, at the end of the three-year performance period, at least the threshold
performance level has been attained. To the extent that the payout level attained is less than 100%, the difference
between 100% and the units earned and distributed will be forfeited. Eligible participants may also earn additional
units of our common stock, which would increase the potential payout from 101% to 200% of the units granted,
depending on LII’s performance over the three-year performance period. The payout level for shares paid during
years ended December 31, 2010, 2009 and 2008 was 127.68%, 200% and 200%, respectively.

Performance share units under the 2010 Incentive Plan are classified as equity awards, with the fair value of
each unit equal to the average of the high and low market price of the stock on the date of grant for units granted
prior to December 2007. The fair value of units granted after December 2007 is the average of the high and low
market price of the stock on the date of grant discounted by the expected dividend rate over the service period. Units
are amortized to expense ratably over the service period. The compensation expense for any additional units which
may be earned is estimated each reporting period based on the fair value of the stock at the date of grant. The number
of units expected to be earned will be adjusted, as necessary, to reflect the actual number of units awarded.

A summary of the status of our undistributed performance share units as of December 31, 2010, and changes

Restricted Stock Units

Total compensation expense for restricted stock units was $6.6 million, $6.6 million and $4.6 million for the
years ended December 31, 2010, 2009 and 2008, respectively. The weighted-average fair value of restricted stock
units granted during the years ended December 31, 2010, 2009 and 2008 was $44.80, $35.09 and $27.48 per share,
respectively.

Under the 2010 Incentive Plan, restricted stock units are issued to attract and retain key employees. Generally,
at the end of a three-year retention period, the units will vest and be distributed in shares of our common stock to the
participant.

Restricted stock units under the 2010 Incentive Plan are classified as equity awards, with the fair value of each
unit equal to the average of the high and low market price of the stock on the date of grant for units granted prior to
December 2007. The fair value of units granted after December 2007 is the average of the high and low market price
of the stock on the date of grant discounted by the expected dividend rate over the service period. Units are
amortized to compensation expense ratably over the service period.

Stock Appreciation Rights

Total compensation expense for stock appreciation rights was $4.7 million, $4.4 million and $3.8 million for
the years ended December 31, 2010, 2009 and 2008, respectively. The weighted-average fair value of stock
appreciation rights granted during the years ended December 31, 2010, 2009 and 2008 was $13.75, $10.96 and
$6.84 per share, respectively.

In 2003, we began awarding stock appreciation rights. Each recipient is given the “right” to receive a value
equal to the future appreciation of our common stock price. The value is paid in shares of our common stock. Stock
appreciation rights generally vest in one-third increments beginning on the first anniversary date after the grant date,
and expire after seven years.

Compensation expense for stock appreciation rights granted is based on the fair value on the date of grant and
is recognized over the service period. The fair value for these awards is estimated using the Black-Scholes-Merton
valuation model. We use historical stock price data and other pertinent information to estimate the expected
volatility and the outstanding period of the award for separate groups of employees that have similar historical
exercise behavior to estimate expected life. The risk-free interest rate was based on zero-coupon U.S. Treasury
instruments with a remaining term equal to the expected life of the stock appreciation right at the time of grant.

The fair value of each stock appreciation right granted in 2010, 2009 and 2008 is estimated on the date of grant

using the following assumptions:

19. Reportable Business Segments:

We operate in four reportable business segments of the HVACR industry. Our segments are organized
primarily by the nature of the products and services provided. The table below details the nature of the operations of
each reportable segment:

Transactions between segments, such as products sold to Service Experts by the Residential Heating &
Cooling segment, are recorded on an arm’s-length basis using the market price for these products. The eliminations
of these intercompany sales and any associated profit are noted in the reconciliation of segment results to the income
from continuing operations before income taxes below.

We use segment profit or loss as the primary measure of profitability to evaluate operating performance and to
allocate capital resources. We define segment profit or loss as a segment’s income or loss from continuing
operations before income taxes included in the accompanying Consolidated Statements of Operations excluding
certain items. See the reconciliation of segment profit to Income from Continuing Operations Before Income Taxes
below for more detail on the items excluded from segment profit.

Our corporate costs include those costs related to corporate functions such as legal, internal audit, treasury,
human resources, tax compliance and senior executive staff. Corporate costs also include the long-term share-based
incentive awards provided to employees throughout LII. We recorded these share-based awards as Corporate costs
as they are determined at the discretion of the Board of Directors and based on the historical practice of doing so for
internal reporting purposes.

20. Fair Value Measurements:

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly
transaction between market participants at the measurement date. Our framework for measuring fair value is
established on a three-level hierarchy for fair value measurements based upon the transparency of inputs to the
valuation of an asset or liability as of the measurement date and requires consideration of our creditworthiness when
valuing certain liabilities.

Fair Value Hierarchy

The three-level fair value hierarchies for disclosure of fair value measurements are defined as follows:

Level 1 — Quoted prices for identical instruments in active markets at the measurement date.

Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar
instruments in markets that are not active; and model-derived valuations in which all significant inputs and
significant value drivers are observable in active markets at the measurement date and for the anticipated term of the
instrument.

Level 3 — Valuations derived from valuation techniques in which one or more significant inputs or significant
value drivers are unobservable inputs that reflect the reporting entity’s own assumptions about the assumptions
market participants would use in pricing the asset or liability developed based on the best information available in
the circumstances.

Fair Value Techniques

Our fair value valuation techniques are applied to all of the assets and liabilities carried at fair value. Where
available, the fair values are based upon quoted prices in active markets. However, if quoted prices are not available,
then the fair values are based upon quoted prices for similar assets or liabilities or independently sourced market
parameters, such as credit default swap spreads, yield curves, reported trades, broker/dealer quotes, interest rates
and benchmark securities. For assets and liabilities with a lack of observable market activity, if any, the fair values
are based upon discounted cash flow methodologies incorporating assumptions that, in our judgment, reflect the
assumptions a marketplace participant would use. To ensure that financial assets and liabilities are recorded at fair
value, valuation adjustments may be required to reflect either party’s creditworthiness and ability to pay. Where
appropriate, these amounts were incorporated into our valuations as of December 31, 2010 and 2009, the
measurement dates.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table presents the fair value hierarchy for those assets and liabilities measured at fair value on a

recurring basis (in millions):

(1) Investment in marketable equity securities is recorded in Other Long-Term Assets in the accompanying

Consolidated Balance Sheets. See Note 6 for more information.

(2) For more information on the recording of derivatives in the accompanying Consolidated Balance Sheets, see

Note 8.

Derivatives are primarily valued using estimated future cash flows that are based directly on observed prices
from exchange-traded derivatives and, therefore, have been classified as Level 2. We also take into account the
counterparty’s creditworthiness, or our own creditworthiness, as appropriate.

Other Fair Value Measurements

The carrying amounts of cash and cash equivalents, accounts and notes receivable, net, accounts payable and
other current liabilities approximate fair value due to the short maturities of these instruments. The fair values of
each of our long-term debt instruments are based on the quoted market prices for the same issues or on the amount of
future cash flows associated with each instrument using current market rates for debt instruments of similar
maturities and credit risk. The estimated fair value of long-term debt (including our domestic revolving credit
facility, capital lease obligations, foreign obligations and any related current maturities) was $114.6 million and
$242.5 million as of December 31, 2010 and 2009, respectively. The estimated fair value of our senior unsecured
notes was $203.0 million as of December 31, 2010. The fair values presented are estimates and are not necessarily
indicative of amounts for which we could settle such instruments currently or indicative of our intent or ability to
dispose of or liquidate them.

24. Subsequent Events (unaudited):

On January 14, 2011, we completed a transaction with The Manitowoc Company, Inc. by which we to acquired
substantially all the assets of its Kysor/Warren business. Kysor/Warren is a leading manufacturer of refrigerated
systems and display cases for supermarkets throughout North America. Under the terms of the agreement, the total
consideration for the acquisition is $138 million, subject to a post-closing purchase price working capital
adjustment.

25. Condensed Consolidating Financial Statements

The Company’s senior unsecured notes are unconditionally guaranteed by certain of the Company’s subsid-
iaries (the “Guarantor Subsidiaries”) while they are not by other subsidiaries (the “Non-Guarantor Subsidiaries”).
As results of these guarantee arrangements, we are required to present the following condensed consolidating
financial statements.

The condensed consolidating financial statements reflect the investments in subsidiaries of the Company using
the equity method of accounting. Intercompany account balances have been included in Accounts and Notes
Receivable, Other (Current) Assets, Other Assets, net, Short-Term Debt, Accounts Payable, and Long-Term Debt
line items of the Parent, Guarantor and Non-Guarantor balance sheets. The principal elimination entries eliminate
investments in subsidiaries and intercompany balances and transactions.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

As required by Rule 13a-15 under the Securities Exchange Act of 1934, we carried out an evaluation, under the
supervision and with the participation of our current management, including our Chief Executive Officer and Chief
Financial Officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered
by this report. There are inherent limitations to the effectiveness of any system of disclosure controls and
procedures, including the possibility of human error and circumvention or overriding of the controls and
procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance
of achieving their control objectives. Based on that evaluation, the Chief Executive Officer and Chief Financial
Officer have concluded that, as of December 31, 2010, our disclosure controls and procedures were effective to
provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under
the Securities Exchange Act of 1934 is recorded, processed, summarized and reported, within the time periods
specified in the applicable rules and forms, and that such information is accumulated and communicated to
management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions
regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes during the quarter ended December 31, 2010 in our internal control over financial
reporting that have materially affected, or are reasonably likely to materially affect, our internal control over
financial reporting.

This  Annual  Report  contains  forward-looking  statements  within  the 
meaning of Section 27A of the Securities Act of 1933, as amended, and 
Section 21E of the Securities Exchange Act of 1934, as amended, that 
are based on information currently available to management as well as 
management’s  assumptions  and  beliefs.  All  statements,  other  than 
statements of historical fact, included in this Annual Report constitute 
forward-looking statements within the meaning of the Private Securities 
Litigation  Reform  Act  of  1995,  including  but  not  limited  to  statements 
identified by the words “may,” “will,” “should,” “plan,” “predict,” “anticipate,”

statements are subject to certain risks and uncertainties. For informa-
tion concerning these risks and uncertainties, see LII’s publicly available 
filings  with  the  Securities  and  Exchange  Commission.  Should  one  or 
more  of  these  risks  or  uncertainties  materialize,  or  should  underlying 
assumptions  prove  incorrect,  actual  results  may  differ  materially  from 
those  in  the  forward-looking  statements.  LII  disclaims  any  intention  or 
obligation to update or review any forward-looking statements or informa-
tion, whether as a result of new information, future events or otherwise.
