We are a family-owned company, and operate locally in the Sioux Falls area. As a team, we are dedicated to providing the best customer service possible at competitive price. We've been in business since 1943, established by brothers, Ted and George Thorson. George's son, Rob, took ownership in 1986 and made the move to our current shop on East Third Street. Rob's daughter is now taking to the trade, making for the third generation of the company. Jackie graduated from Southeast Technical Institute, being the first woman to complete the HVAC/R program. With our combined father-daughter dedication, we ensure everyone gets the best customer service.
