History

Previous logo

The company was founded in 1895, in Marshalltown, Iowa, by Dave Lennox, the owner of a machine repair business for railroads. [1] Inventors Ezra William Smith and Ernest Bryant brought their idea for a riveted steel coal-fired furnace to his machine shop to build parts for a prototype. In lieu of payment, Lennox accepted their patent, obtaining rights to the idea and founded the Lennox Furnace Co. [2]

In 1904, DW Norris acquired the company. He managed the company until his death in 1949. [3]

From 1964 to 1965, Lennox produced a small crawler tractor and mower called the Lennox Kitty Track 600. It featured a 6 hp (4.5 kW) Briggs & Stratton engine and a 32" mower deck. [4]

In 1999, the company became a public company via an initial public offering. [5]

A 2018 tornado destroyed the plant in Marshalltown, but the company would rebuild it. [6] As of 2024, there were over 750 workers employed at that location. [7]

Acquisitions and divestitures

In 1971, the company sold its low pressure gas cylinder business to Worthington Industries. [8]

In 1973, Lennox acquired Heatcraft, including the Larkin, Bohn, Chandler, and Climate Control brands. [9]

In 1998, the company acquired Pyro Industries, a manufacturer of pellet stoves. [10]

In December 2010, the company acquired Kysor/Warren from The Manitowoc Company for $138 million. [11]

In September 2023, the company sold its European commercial HVAC and refrigeration businesses to funds managed by Syntagma Capital. [12]

In October 2023, the company acquired AES. [13]
