Routine maintenance was great. Prompt and communicative.

Brandon from Kettle Moraine Heating came out to diagnose our A/C unit which had stopped working. Brandon was able to easily fix the problem and get our house cooled down again. He was also very knowledgeable and professional when providing details about purchasing a new furnace and A/C unit since ours is 22 years old already. Thank you Kettle Moraine Heating and we look forward to doing business with you again.

Mitch was on time, very professional and knowledgeable

Brian was very honest and a great guy. Not his fault, but felt the repair was overpriced.

Craig led a great team and did a clean and efficient job in installing a new furnace and heat pump. I hope the Lennox equipment proves to be reliable and effective.

The team was friendly, thorough, and neat! They did an awesome job!

The whole team did a great job all around!!! We had them out a couple times. From fixing our A/C to replacing our furnace. Very knowledgeable and professional. Special thanks to Tim, Brian and Scott. You guys gave us great advice and knowledge. Thank you!

Lane Williams is a very pleasant guy and knew what he was doing the entire time. Thank you so very much for your great service.

The technician was extremely knowledgeable and explained everything perfectly.

Brandon did a wonderful job servicing my furnace. He was on time, polite and respected my home. He carefully explained everything he was doing. Great job!!

Patrick did a great job doing a maintenance tune up on our AC unit. He replaced a part that was showing its age while it was still under warranty. Things like this go a long way and speaks volumes about the company. We recommend Kettle Moraine whenever the opportunity arises. Thank you for the fantastic customer service. I have never been disappointed.

Jon the technician from Kettle Moraine came out to service both furnace and A.C. he was punctual and introduce himself when I opened the door. I directed him to where the furnace ,thermostate and air-conditioner is located. I previously purchased the "Peace of Mind" package. Jon addressed all the checkpoints of this package and concluded that no problems were found. I appreciate Jon and Kettle Moraine looking out for me and my heeting and A.C. needs these last few years. Before I close, I appreciate that Jon left my house as clean as he found it! Thank you! Kevin

Great friendly guy! Went about his work and gave us the report.

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.

Service was for tune up very professional and explained everything
