Tom Koresch

Our 35 years old furnace died on us.Glad we called Kettle Moraine Heating and cooling. Great communication, great people, and fast response time.

Trish D

Humidifier installed by Jacob. Very polite and informative. Initially there was a slight issue with getting the correct humidifier installed but that was resolved quickly and Jacob was able to return the same week with the best fitting unit.It’s only been a half hour and I can already feel the difference in the air quality. Since this is day one only I can’t really provide a complete review on the unit, the Aprilaire 700, but will post an update once we have used it for a bit.Overall, at this point, the service was great.

David Alvarez
