Our History


Our founder, Gus Larson, emigrated alone at the age of 16 from his home in Gothenburg, Sweden in the early 1900s. While working as a refrigeration mechanic in Chicago, he saw the need for local refrigeration parts depots. He founded the Gustave A. Larson Company as a refrigeration parts jobber in 1936 at a small storefront in Madison, Wisconsin.

As the company and Gus’s passion to influence the industry flourished, he quickly opened up branches throughout the state of Wisconsin, in Milwaukee, Oshkosh, Appleton, Green Bay, Wausau, and Eau Claire, as well as Rockford, Illinois. By the early 1960s, he was operating 20 locations in Illinois, Iowa, Wisconsin, and Florida.


Even though the business has gone through many changes since the 1960’s, the Larson Company is still family owned and operated, and has grown to be the Midwest’s leading wholesale distributor of Heating, Ventilation, Air Conditioning and Refrigeration (HVACR) equipment, parts and supplies.
