Corporate History

Dave Lennox developed and patented his first furnace in 1895. He sold the business to a small group of investors in 1904, who named the company the Lennox Furnace Co. In 1955, the company changed its name to Lennox Industries, to reflect its change in emphasis from furnaces alone to furnaces, air conditioning and agricultural equipment.

In 1984, Lennox International Inc. was created as a holding company for Lennox Industries. Lennox International Inc. owns three independent subsidiaries: Lennox Industries, Heatcraft and Armstrong. Lennox International was privately held until it completed an initial public offering on July 28, 1999.

Lennox has sales offices in the United States and Canada.

Product Lines

Lennox makes gas and oil furnaces, air conditioners and heat pumps that fall into the Signature, Elite and Merit series. Its gas furnaces have efficiency ratings that range from 80 to 98.2 percent AFUE, and cover a range of options in speeds, stages and efficiencies. Two oil furnaces are offered, the SLO183V and ELO183. The company's air conditioners can reach as high as 21.2 SEER, with these high-end options promoted as being particularly quiet. Several ductless systems also are supplied.

Environmental Impact

Lennox's environmental protection policy states that the company will comply with international laws, educate its employees, use non-polluting technologies and operate with recycled materials. It touts its 21-SEER air conditioner, its SLP98V heater and its SunSource solar-powered systems as examples of technologies that help the environment by requiring less power to operate. Lennox was the first company to be named an Energy Star Manufacturing Partner of the Year. It also is a member of the Thermostat Recycling Corp. and of the Canadian Thermostat Recovery Program.
