Lennox International Inc

A maker of home heating and cooling, Lennox International builds residential furnaces, air conditioners, and heat pumps under brands like Lennox, Armstrong Air, and Ducane, plus commercial refrigeration gear under Heatcraft and Bohn. The company traces back to 1895 in Marshalltown, Iowa, when machinist Dave Lennox accepted a patent for a riveted-steel furnace in lieu of payment for his work. A good party fact: Dave's namesake "Dave Lennox" mascot, a cartoon caveman in a fur coat, has been the face of the brand for decades.
