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

“The two service technician, Tristan and Besto performed a seasonal service check-out before summer usage. They were excellent and provided me key information about my air-condition unit, filter, and brought to my attention the two vents in the storage room that we were not even aware of since we just moved into the home in late December. I'll be sure to use them again if anything would go wrong and/or for regular service maintenance and request the same two technicians.”
