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.
WHAT OUR CUSTOMERS ARE SAYING
“As usual, the technicians were professional, finished the check up and even talked me into a new piece of equipment for the furnace. Great work!”
“Technician T. G. was professional, knowledgeable, and efficient.
He explained everything that he was doing, what the problem was, showed me the part that was not working and replaced it.
He further explained how to best manage cooling my house in the extreme heat, Wisconsin is having this summer.”
