SOUTHEAST WISCONSIN’S HVAC EXPERTS
ESTABLISHED IN 1962
OUR STORY
Continuing a Tradition of Exceptional Heating and Cooling Services
What began in a garage in 1962—with Gordy and John Cole’s commitment to offering honest, high quality HVAC service—continues today at Interstate Heating Co. in Sussex. We’ve grown to offer the latest heating, cooling, and air quality products, and our service area now covers all of southeastern Wisconsin.
We are three generations strong and still follow the most basic rule of business: we treat our customers the way we want to be treated.
