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.

“Five days ago, I did a Google Review that I really didn't want to submit, because of a service call that left us questioning if our furnace was really repaired to the standard we've come to expect from Interstate Heating over the past 30 years. Turns out our worries were warranted as days later, we noticed water leaking from the unit. We called in and talked to Matt. He listened to our story and was able to send technician Chris Carne at the next available opening. We can't possibly say enough good things about the service that we received from Chris. He immediately found the problem, thoroughly explained how he would be making the repair, had the parts and tools with him and completed the work quickly with no extra charges or sales pitches. It's now been 2 days and the house is warm and the furnace is dry. Thanks to the great customer service by Matt and the outstanding work done by Chris, we now have renewed confidence in Interstate Heating that made us choose them 30 years ago. We will remain with Interstate as long as Matt and Chris continue their awesome service! Thank you so much!!!”
