Paul with Kettle Moraine was absolutely fantastic. He was able to identify a problem that our usual HVAC servicer was unable to on multiple occasions. He was friendly, professional and very thorough. I can not be any happier with the services we received. Thank you Paul!!!!!

Some of the hottest weather on record in Wisconsin and our air conditioner failed. Paul came out and within an hour we knew the problem and how to fix it and when the repair would be done and how much was estimated.👍

Fast to respond, highly qualified technicians. Kettle Moraine Heating and Cooling did a great job getting us back up and running in the summer heat. Ask for Jacob. He was a great tech. Knowledge, experienced, and great to talk with.

They were wonderful from the start. Called on a Monday they came out the next day. And installed the new furnace/air conditioner that Friday. Why because they knew how hot it was going to get on the weekend. Very professional, great customer service and we’re so nice. I highly recommend them for all your needs with HVAC, Plumbing and Electrical.

Techs Paul and Mark, both dug into an ongoing hvac issue that I had which was not able to be diagnosed by other companies I tried. They questioned and brainstormed ultimately finding an answer and backed it up with documentation from the furnace manufacturer.
Also very good communication from the office concerning their arrival time. Texted photos of the techs to me before their arrival.

Highly recommended! I had my whole central air unit replaced and the new one works flawlessly. The installation was quicker than anticipated, and by the end of it everything was cleaned up like nothing ever happened. The crew was friendly and knowledgeable and answered all the questions I had. Going forward it will be my go-to for any HVAC needs!

Damyon did a great job taking care of our AC unit. He's very knowledgeable, pleasant, and professional. He was on time and took care of the problem efficiently. This is the second time he takes care of us. I highly recommend him for all hvac jobs. The cost was very reasonable too. Thank you, Damyon!
