We had a wonderful experience with Kettle Moraine Heating and AC, from our consultation with Matt who was extremely thorough, helpful and explained everything in a way I could understand. To Dustin who walked us through the financing process with ease, and Derek and his team who came out and installed our brand new ac unit and did an excellent job removing the old unit in a quick and efficient manner and making sure to clean up when they were done. Needless to say with a 10 month old and having our ac not working for basically a month it was especially nice to have them be able to come the next day and get our ac up and running for us!! Very happy and our ac runs beautifully!

Miguel, came to tuneup my AC. Unfortunately, I had been having problems recently. He was very thorough and diagnosed the issue with my unit, spending additional time to check my current system out. My experience today with Miguel was very positive and other techs I have had were also experienced and well trained. Would recommend highly to anyone looking for HVAC service.

Brett Z is always our guy from Kettle Moraine. He ALWAYS does an awesome job. He does a very thorough job. He is also really personable.

KM installed my new Heat pumps today. The process went very well and the technicians were adept and professional. Cole was exceptionable navigating through the cumbersome federal IRA/HEARS and Wisconsin Focus on Energy rebate programs. Many Thanks! Dr. Bergman

Very professional and understanding, and great costumer service.

Great service, and professional

Jacob was on time and his communication, workmanship and attention to detail was excellent!

After my house was struck by lightning my inspection was very thorough and professional as well as educational. Appreciate all the support and help. Highly recommend Joel and his team at Kettle Moraine!

Very informative. Explained everything. Not high pressure. On time for installation. Cleaned up nicely.

I had a Generac installed and it was actually a pleasant experience … would highly recommend them

Great customer service.

Very personable. Very concerned about doing a great job and making sure we understood everything. Well done Mike and Justin.

Khamya from Kettle Moraine Heating arrived on time to tuneup my furnace & humidifier. She did a great job in a short time, cleaned up after herself & was very friendly.

Jacob performed routine maintenance on our HVAC system. He noticed that the capacitor on the air conditioning unit was wearing out. Fortunately it was still under warranty, and Jacob replaced it. We’ve been pleased with all of Kettle Moraine’s technicians.

Prompt friendly & knowledgeable

Our furnace/AC replacement was scheduled quickly, just a couple days after meeting for a quote. We were provided options for good, better, best and feel confident in the products we purchased. Bill and his team did an excellent job at install - cleaned up and explained the new systems to us before they left!

Sam, the sales rep was very knowledgeable. He bent over backwards for me. Due to my schedule it was hard for a larger project like mine to get done quick enough to not affect what I do for work. 5 guys showed. Ryan, scott, JJS, Zach and Brett got all the new stuff in here and the old stuff out asap. Then the electrician and another guy showed up, gut their part done efficiently and let the original five knock this thing out. It was no small project either. Furnace and AC plus upsizing multiple ducts, cutting through the floors to upsize the floor registers, etc. Maybe 8 hours and it was done. I've been in residential construction of some form or fashion for a long time and I can tell you I wouldn't go anywhere else after this experience and I will refer this company to others.

Miguel was on time, professional and very friendly. Performed maintenance on our furnace efficiently .

Khamya was great! Right on time, pleasant and professional. She did a great job, thank you!

KM completed water heater maintenance for us for the first time. The technician was very polite and knowledgeable.

Great service and a friendly face

Erik and Jim did an outstanding job on our AC tune up and on replacing our dual capacitor! Erik took the time to explain what the part did, and shared current readings and past readings that Jim had recorded previously. Appreciated the before and after pictures of our AC unit cleaning.

Lucas, my technician was prompt and set about doing his job in a timely and efficient manner. I had some questions about operating my generator and he answered them several times over until I felt that I understood them. He was very patient with me. I appreciate that so much.

Jeremy is very Prompt friendly very knowledgeable and professional great service

Very professional and educational. He and Lane were very respectful of our home
