Business Overview



We operate in three reportable business segments of the heating, ventilation,
air conditioning and refrigeration ("HVACR") industry. Our reportable segments
are Residential Heating & Cooling, Commercial Heating & Cooling, and
Refrigeration. For additional information regarding our reportable segments, see
Note 2 in the Notes to the Consolidated Financial Statements.

Our fiscal quarterly periods are comprised of approximately 13 weeks, but the
number of days per quarter may vary year-over-year. Our quarterly reporting
periods usually end on the Saturday closest to the last day of March, June and
September. Our fourth quarter and fiscal year ends on December 31, regardless of
the day of the week on which December 31 falls. For convenience, throughout this
Management's Discussion and Analysis of Financial Condition and Results of
Operations, the 13-week periods comprising each fiscal quarter are denoted by
the last day of the respective calendar quarter.

We sell our products and services through a combination of direct sales,
distributors and company-owned parts and supplies stores. The demand for our
products and services is seasonal and significantly impacted by the weather.
Warmer than normal summer temperatures generate demand for replacement air
conditioning and refrigeration products and services, and colder than normal
winter temperatures have a similar effect on heating products and services.
Conversely, cooler than normal summers and warmer than normal winters depress
the demand for HVACR products 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 are components, raw materials,
factory overhead, labor, estimated warranty costs, and freight and distribution
costs. The principal raw materials used in our manufacturing processes are
steel, copper and aluminum. In recent years, pricing volatility for these
commodities and related components, including the impact of imposed tariffs on
the import of certain of our raw materials and components, has impacted us and
the HVACR industry in general. We seek to mitigate the impact of volatility in
commodity prices through a combination of price increases, commodity contracts,
improved production 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.

Impact of COVID-19 Pandemic



A novel strain of coronavirus ("COVID-19") has surfaced and spread around the
world, including to the United States. In March 2020, the World Health
Organization declared COVID-19 a pandemic. Currently the COVID-19 pandemic has
disrupted our business operations and caused a significant unfavorable impact on
our results of operations in 2020. The COVID-19 pandemic is creating supply
chain disruptions and higher employee absenteeism in our factories and
distribution locations.

As the COVID-19 pandemic continues, health concern risks remain. We cannot
predict whether any of our manufacturing, operational or distribution facilities
will experience disruptions, or how long such disruptions would last. It also
remains
                                       21
--------------------------------------------------------------------------------

unclear how various national, state, and local governments will react if the
distribution of vaccines is slower than expected or new variants of the virus
become more dominant. If the COVID-19 pandemic worsens or the pandemic continues
longer than presently expected, COVID 19 could impact our results of operations,
financial position and cash flows.

Financial Overview



Results for the second quarter of 2021 were driven by year over year sales and
profit increases across all of our business segments. The Residential Heating &
Cooling segment saw a 30% increase in net sales and a $62 million increase in
segment profit. The Commercial Heating & Cooling segment had a 34% increase in
net sales and a $10 million increase in segment profit. The Refrigeration
segment had a 37% increase in net sales and a $5 million increase in segment
profit.

Financial Highlights

The net change in unrealized (gains) losses on unsettled futures contracts was
due to changes in commodity prices relative to the unsettled futures contract
prices. For more information on our futures contracts, see Note 7 in the Notes
to the Consolidated Financial Statements. For more information on special legal
contingency charges and asbestos-related litigation, see Note 4 in the Notes to
the Consolidated Financial Statements. The environmental liabilities related to
estimated remediation costs for contamination at some of our facilities.

Restructuring Charges

Restructuring charges were $1 million in the second quarter of 2021 compared to $10 million in the second quarter of 2020. Restructuring charges related to ongoing cost reduction actions taken in prior periods.

Gains and Losses related to Natural Disasters

The insignificant charges recorded during 2020 were for continuing costs incurred related to natural disasters that occurred in prior years.

Income from Equity Method Investments



We participate in two joint ventures that are engaged in the manufacture and
sale of compressors, unit coolers and condensing units. We exert significant
influence over these affiliates based upon our ownership, but do not control
them due to venture partner participation. Accordingly, these joint ventures
have been accounted for under the equity method and their financial position and
results of operations are not consolidated. Income from equity method
investments of $4 million in the second quarter of 2021 was down slightly
compared to the second quarter of 2020.

Interest Expense, net

Interest expense, net was down $1 million to $6 million in the second quarter of 2021 from $7 million in the second quarter of 2020 due to lower borrowing costs.


                                       23
--------------------------------------------------------------------------------

Income Taxes

Our effective tax rate was 18.6% for the second quarter of 2021 compared to 21.4% for the second quarter of 2020. The rate decreased primarily due to an increase in excess tax benefits from stock based compensation.

We expect our annual effective tax rate in 2021 to be approximately 20%, after excluding the impacts of excess tax benefits recorded under ASU No. 2016-09.

Restructuring Charges



Restructuring charges were $1 million in the first six months of 2021 and $11
million for the six months ended June 30, 2020. Charges in prior years related
to several cost reduction actions taken in response to the economic impact of
the COVID-19 pandemic on our business.

Gains and Losses related to Natural Disasters

The insignificant charges recorded during 2020 were for continuing costs incurred related to natural disasters that occurred in prior years.

June 30, 2021 was consistent with the amount for the six months ended June 30,
2020.

Income Taxes



Our effective tax rate decreased to 19.3% for the six months ended June 30, 2021
compared to 26.8% for the six months ended June 30, 2020 primarily due to higher
excess tax benefits from stock-based compensation and the recording of a
valuation allowance on certain foreign deferred tax assets recorded in the first
quarter of 2020.

Working capital needs are generally greater in the first and second quarters due to the seasonal nature of our business cycle.
