The team at Kettle Moraine Heating & Air Conditioning really know their stuff. My air conditioner issue was hard to diagnose. They stuck with it and found and fixed the problem. Great Work!

Valerie - Nashotah, WI

Kettle Moraine Heating & Air Conditioning walked me through the replacement process and made it very easy to understand and afford. I would highly recommend them.

Dan - Sussex, WI

Had a new furnace/AC installed and very happy with kettle moraine. They were prompt, courteous and did a great job keeping us informed throughout the entire process. They cleaned everything up when they were finished and took the time to show me how everything operates. Very glad that we went with them.

Both people I spoke with on the phone were great. They were able to have someone come out the same day. Luke, who fixed the furnace was polite and professional. I’ll definitely be a repeat customer and will be recommending them to family and friends in the area!
