Carlson & Stewart Refrigeration, Inc. started as Carlson Sales & Service in 1935. Founded by Roy Carlson, the company sold and serviced household appliances.

As his business grew, so did Carlson’s knowledge of refrigeration, and he soon expanded the business to include mechanical refrigeration for family dairy farms, the local butcher shops, small town creameries, and community grocery stores. When these businesses started to form regional dairies, packing plants, and supermarkets, Carlson Sales & Service also expanded to meet the evolving need.

In 1948, Bud Stewart joined his uncle Roy in the refrigeration business. Carlson Sales & Service was incorporated in 1958 as Carlson & Stewart Refrigeration, Inc. With four employees, they served customers within a 100 mile radius of Marshall, MN.

Today, Carlson & Stewart Refrigeration, Inc. is a design-build contractor specializing in commercial and industrial refrigeration systems for clients in Minnesota, the Dakotas, Iowa, and Wisconsin. In late 2011, Carlson & Stewart acquired Central Minnesota Refrigeration, Inc., Sauk Rapids, MN. The acquisition added 11 service technicians, 15 employees and additional clients in central Minnesota.
