Lennox History

David Lennox founded the company in Marshalltown, Iowa in 1895. While he was the owner of a machine repair business that served railroads, Ernest Byron and Ezra William Smith, two inventors at the time, came to his machine shop with their brilliant idea to make a riveted steel coal-fired furnace. They needed parts for a prototype they developed and offered David Lennox a share in their venture in lieu of payment. David like the idea and received rights to their patented design.

David Lennox sold the original company in 1904 to DW Norris. Lenox Furnace Co. was incorporated the same year to improve on the original furnace design that brought about advancements in climate control, heating, and cooling solutions. A warehouse was added in 1923. Two years later, a factory came up in Syracuse, New York. Lennox pioneered the forced air furnace to heat residences in 1935 and contributed to the war efforts in 1943 with heating equipment, bomb and aircraft parts.


On his death in 1949, DW Norris relinquished his position and ownership of the company to his descendants. In 1952, the residential central air-conditioning system was introduced in Canada. Lennox expanded operations in 1960 with a facility in Basingstoke, England; warehouses and sales offices in Germany and Holland. From 1964-65, Lennox moved into the garden-and-lawn industry, launching the Linux Kitty Track, a crawler tractor and mower. This had a 32“ mower deck powered by a 6 hp 4.5 kW Briggs & Stratton engine.

Lennox pioneered in 1965 the packaged direct multi-zone rooftop unit for cooling and heating. The company sold its low-pressure gas cylinder business to Worthington Industries in 1971 taking its first steps into diversification. Lennox took over the refrigeration products firm Heatcraft in 1973 including the Chandler, Bohn, Larkin, and Climate Control brands. The company added the Warren/Kysor brand to its Heatcraft offers and developed its two-speed hermetic compressor to reduce air-conditioning energy costs. In 1982, Lenox pioneered its high-efficiency gas furnace and became a subsidiary of Lennox international Inc in 1984.

Heatcraft Inc. was established in 1988 to implement the company’s 48-hour oil replacement program for non-residential air-conditioning systems. CompleteHeat, it’s high-efficiency heating system, was introduced in 1994 after which Lennox went global with Lennox Global Ltd. (LGL) in 1995. The company developed its Beacon Control System in 1996 to correct refrigeration system maintenance and installation issues. In 1997, LGL expanded operations into Latin America, Europe, and Asia. The company went public in 1999. Lennox introduced the industry’s most efficient and quietist air-conditioner, the HSX19, in 2003.
