About

Four Generations of Service

Kohlman Hardware, Heating and Tinning began when a small town hardware store was purchased by Frank Kohlman in 1913, then owned by Herman, Robert and most recently Douglas Kohlman. The original building was located in the middle of downtown and the company continues to be based in St. Cloud, Wisconsin. In 1970, a decision was made to specialize in heating, ventilation and air-conditioning, and today our company employs thirteen full and part-time team members. Our technicians receive specialized training through apprenticeship programs in sheet metal fabrication, pipe fitting, and heating and refrigeration service, as well as on-site training at our equipment manufacturers’ training centers.
