After a number of quotes from local HVAC companies we selected Kettle Moraine Heating & Air and could not be happier. The furnace and A/C units we choose were head and shoulders above the competition and at a similar price-point and a considerable greater value than the other guys. The appointment was set and the group descended on our home like a military operation. All the techs were so friendly, especially Matt, who made sure I was familiar with our new system and all that it could do. Our home is much more comfortable thanks to the gang at Kettle Moraine Heating and Air. Give them a call, you won't be disappointed!

Matt was on time, friendly, professional, knowledgeable, thorough, informative, open and honest. He reviewed his service process, findings, suggestions and recommendations. I will request him for future service opportunities and recommend Kettle Moraine to anyone in need of HVAC services.

Jacob from kettle moraine heading and air cakes saying he could fit us in early which was appreciated. He was very polite and responsive. Overall a great service and interaction.

I chose Kettle Moraine H&C after getting 3 comparable quotes. I chose them because they offered a higher quality ac unit and better service warranties than the other companies. I also took advantage of their financing offer, which was not an option with the runner up. The team was on time, worked very hard, were personable, and everything is working great. I still can't believe I have central air, it's wonderful. I cannot hear that its on, it isn't blowing wildly in my face, it's a stealthy flow of cool air with no basement smell! I look forward to working with these guys again. I am still upgrading my electric and will give them the business. Thank you guys for getting everything together for me. You and the electrician get 10/10 stars from me and Wilbur the Wonderdog.

Fantastic service.

On 8/26/26, Julian Espinosa Operations Mgr for Kettle Moraine HVAC arrived at our residence for the specific purpose of inspecting the structure of the roof where the a/c is located. Julian stated that the roof area IS good and that Kettle Moraine would be glad to continue servicing our units. We have, in the past, been favorably impressed with the thorough tune-up service performed by Kettle Moraine Heating. After Julian's response regarding our a/c location, we're happy to agree that they will continue to be our service provider.

Jacob called to let me know he was on his way over within the 4 hour window. He did a thorough job with the ac tune up and addressing a concern I had with the furnace. I was provided before and after pictures of the condenser unit and the evaporator coils.

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.

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
