Is Lennox a Canadian company?

No, Lennox is not a Canadian company; Lennox is an American company, specifically Lennox International Inc., founded in 1895 by Dave Lennox in Marshalltown, Iowa, and currently headquartered in Richardson, Texas, near Dallas, with about 13,000 employees and publicly traded on the New York Stock Exchange. Lennox is one of the largest HVAC manufacturers in North America making residential furnaces, air conditioners, heat pumps, and commercial rooftop units. While Lennox is American, it does have significant operations and market presence in Canada, with Canadian distribution, dealers, and products certified to CSA standards for Canada, and it is a popular brand in Canada alongside Carrier, Trane, and Daikin. Some confusion may arise because Lennox has a similar name to Canadian locations or because it operates in Canada, but its headquarters, incorporation, and primary manufacturing are in the United States, with plants in Iowa, Arkansas, and other US locations as well as Mexico. Canadian-owned HVAC companies include Napoleon Heating and Cooling headquartered in Barrie, Ontario. So Lennox is American, not Canadian, though it is widely sold and serviced in Canada through authorized dealers.
