Duncan Supply Company Revenue and Competitors

Duncan Supply has been the premier wholesale distributor of refrigeration, air conditioning, and heating equipment in central Indiana and Illinois since 1936. In 1932 when Russell Kenneth Duncan, founder of Duncan Supply Co., quit his job with Frigidaire to pursue his dreams and open his own business. He and his brother Ralph saw an opportunity in the growing refrigeration industry and started Duncan Brothers Refrigeration Repair Company. It was the first, and soon became the largest, independent service business in Indianapolis, prospering in spite of the Depression. In 1936, Russell and his wife Mildred sold their interest in the company to his brother to concentrate on wholesale refrigeration parts distribution. The new business, Duncan Supply Company, was relocated to 937 N. Illinois Street in 1940 and was incorporated 7 years later. Duncan Supply has 10 branch locations: Bloomington (IN), Champaign (IL), Elkhart (IN), Fort Wayne (IN), Indianapolis (IN), Kokomo (IN), Lafayette (IN), Muncie (IN), Plainfield (IN) and Terre Haute (IN).
