Lennox International reports record third quarter sales and net income;
Raises full-year 2005 guidance

     (DALLAS, October 26, 2005) — Lennox International Inc. (NYSE:LII) today announced record sales and net income for third quarter 2005. Revenue increased 20 percent to $928 million, with foreign exchange contributing one percent to sales growth. Net income was $49 million, up 158% from $19 million the prior year. Diluted earnings per share were $0.68, compared with $0.29 in the third quarter last year. Adjusting third quarter 2004 results for a $9 million loss from discontinued operations, income from continuing operations was $28 million, or $0.42 per diluted share.

     In the third quarter 2005, the company recorded a cumulative effect of accounting change of $0.2 million income net of tax, reflecting early adoption of SFAS 123R — Share-Based Payments, which addresses the accounting for stock-based compensation.

     The company generated $89 million in cash flow from operations and $15 million was invested in capital expenditures, resulting in strong free cash flow of $74 million. As of September 30, 2005, total debt was $236 million, a reduction of $83 million from third quarter 2004. The reduction includes $41 million in convertible notes that were converted to common shares of LII stock prior to the end of the quarter.

     “LII had an outstanding third quarter,” said Bob Schjerven, chief executive officer. “The improvement was broad-based, with all our business segments realizing increased revenue and segment profit. Robust demand for residential equipment and service due to hot summer weather contributed to our strong results, as did improved domestic demand for commercial equipment. In addition, the price increases we have implemented in our equipment businesses are sticking.

     “We are optimistic this momentum will continue into the fourth quarter, and are raising our full-year 2005 earnings per share guidance from $1.60 to $1.70 to a range of $1.75 to $1.80.” This range represents a 26% to 29% improvement over the $1.39 EPS from continuing operations before goodwill impairment reported in 2004. The company also raised its 2005 revenue growth expectations to approximately 10 percent from the high-single digits previously announced.

Business segment highlights:

     Heating & Cooling: Benefiting from hot summer temperatures, LII’s Residential Heating & Cooling revenue rose 28 percent to $465 million, with foreign exchange contributing one percent of the growth. Segment profit increased 50 percent to $67 million, driven by higher volumes and improved pricing. Segment profit margins expanded 200 basis points to 14.4 percent. “Our activities to comply with the new 13 SEER minimum energy efficiency standard for residential air conditioning are on track,” Schjerven said. “We believe the movement to 13 SEER will be a net positive for our company and the industry, and we will be ready with a competitive range of products when the regulation takes effect January 23 of next year.”

     Commercial Heating & Cooling continues to make progress. Revenue was up 16 percent to $192 million, with no meaningful impact from foreign exchange. Strong sales increases to domestic national accounts and through commercial sales districts that focus on contractor customers easily offset lower sales in Europe, where the market remains stagnant. Segment profit grew 34 percent to $27 million, again due to higher volumes and improved pricing. Segment profit margins expanded to 14.0 percent from 12.1 percent last year.

     Service Experts: Sales for Service Experts were up 14 percent to $172 million, a 12 percent increase when adjusted for currency fluctuations. Segment profit of $8 million, or 4.6 percent of sales, compares very favorably with a $1 million loss in last year’s third quarter, with improved revenue as the primary driver. Third quarter 2004 was negatively impacted by an

increase in reserves of nearly $2 million for obsolete and slow-moving inventory. Service Experts’ performance continues to meet internal expectations and the segment is on track to achieve a low-single digit segment profit margin percentage for the full year.

     Refrigeration: Revenue rose 7 percent, up 3 percent in constant currencies. Segment profit increased 6 percent to $12 million, with the improvement coming from domestic operations. When adjusted for foreign exchange, international sales were flat, with increases in South America offsetting declines in the Asia Pacific region. Segment profit from international operations was also relatively flat. Segment profit margins declined by 10 basis points to 10.0 percent.
