LENNOX INTERNATIONAL INC. COMPLETES ACQUISITION OF SERVICE EXPERTS, INC.;
SHAREHOLDERS APPROVE MERGER

         (DALLAS, TX, January 21, 2000) -- Lennox International Inc. (NYSE: LII)
and Service Experts Inc. (NYSE: SVE) announced today they have completed the
merger of their two companies. The transaction creates a separate retail company
within Lennox International of approximately 10,000 employees and estimated 1999
sales of approximately $1 billion, with a leading market position in the North
American retail heating, ventilation, and air conditioning (HVAC) market.

         Shareholders of both companies voted in favor of the transaction at
separate meetings held this morning in Richardson, TX and Brentwood, TN. The two
companies had announced on October 27, 1999 their agreement for Lennox to
acquire Service Experts. The acquisition provides that each Service Experts
share will be converted into a right to receive 0.67 Lennox International
shares.

         The value of the transaction is approximately $300 million, based on
the equity issued and the debt assumed by Lennox. Lennox expects to issue
approximately 12.2 million shares of stock to complete the transaction.

         "We're proud to welcome Service Experts to Lennox International," said
John Norris, Lennox chairman and CEO. "This transaction is consistent with our
previously stated strategy for growth in the retail HVAC market, and will allow
us to accelerate our plans in that area. Both Lennox and the network of
high-quality dealerships Service Experts has established are excited to forge
ahead with our retail strategy."

         Norris said that the Lennox retail management team and the Service
Experts field network had many opportunities to work together over the past
several months. "Based on the working relationships we have already formed with
many Service Experts general managers and field staff, we are more convinced
than ever that these are the type and quality of dealers we want to help build
our retail operations." A meeting between Lennox' retail management team and
many key members of the Service Experts field organization is scheduled for
February 3-5 in Dallas, he noted.

         "For 105 years, Lennox has sold directly to HVAC dealers and worked
side-by-side with all kinds of dealer business models to help their businesses
grow," Norris said. "We believe all of our over 6,000 North American HVAC
dealers -- whether acquired, associate, or independent -- can grow in the
changing HVAC retail market."

         Selling heating, ventilation, air conditioning, heat transfer, and
refrigeration equipment in over 70 countries worldwide, Lennox International
Inc. is one of the world's leading companies specializing in climate control
solutions. It is the parent company of Lennox Industries Inc., Armstrong Air
Conditioning Inc., Heatcraft Inc., and Lennox Global Ltd. Lennox International
stock is traded on the New York Stock Exchange under the symbol "LII."
