Lennox International Inc. ( NYSE: LII) is an intercontinental provider of climate control products for the heating, ventilation, air conditioning, (in the complex colloquially called: HVAC) and refrigeration markets. Lennox also includes the Heatcraft Refrigeration and Armstrong brands.
The company was founded in 1895, in Marshalltown, Iowa, by Dave Lennox, the owner of a machine repair business for railroads. He designed and patented a riveted steel coal-fired furnace, which led to numerous advancements in heating, cooling and climate control solutions. The company was sold in 1904 to DW Norris who managed the company until his death in 1949, following which ownership devolved to his descendants who continued to hold a prominent position in the company in the following decades.   
From 1964-65, Lennox dabbled in the lawn and garden industry by building 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. .
In 1973, Lennox purchased the commercial refrigeration products firm Heatcraft, including the Larkin, Bohn, Chandler, and Climate Control brands.   In 2010, the Kysor/Warren brand was added under the Heatcraft umbrella. 
Today, Lennox International is focused on three core businesses: Residential Heating and Cooling, Commercial Heating and Cooling, and Refrigeration. The company headquarters are in Richardson, Texas, near Dallas.
