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
“Absolutley outstanding service from Eric O! Our daughters A/C unit went out one a very hot day and Interstate sent him out that afternoon. He diagnosed the problem and had the unit back up and running. We truly appreciated his kind expertise!”
“Dylan was very professional and knowledgeable in my yearly tune up of my AC system. He also helps with my annual maintenance of my furnace and I have the ultimate confidence in his work. He answers all my questions and concerns, job well done”
