What Our Customers Say

The customer service from when I called to when they completed the work the next day was excellent. Eric was prompt, polite, clean, and thorough. He explained the work he had done and explained why that work needed to be done. Our Mitsubishi wall-units look and work like new, and we are very happy with the service.

Patrick was a great representative of this business. He was very friendly, considerate, and communicative. He took the time to answer my questions, called ahead to let me know he was on his way, wore shoe covers to keep my house neat, etc. Everyone was friendly at the office when I scheduled this appointment also. I will call again for my next maintenance or repair appointment. Thank you!

You're a professional install! Clean, thorough, understood everything that was being done. Questions asked. Answers came immediately. I'm very pleased that I have used them for a replacement of my heating and air conditioning.

Miles performed a yearly check/up and servicing on my air conditioning! He was thorough and from what I could tell spent extra time removing debris from the filters on the unit. He was knowledgable and pleasant. I’m very satisfied! Barbara England

We had a tankless water heater installed. Josh and Lucas did a really good job! They were timely and efficient, and answered our questions with kindness. They even did a few extra things related to the water heater that really helped us out. Earlier this season, Kettle Moriane also installed an A/C. We are grateful for them!

Daymon from Kettle Moraine HVAC did a fantastic job servicing our A/C unit. He was personable and professional. He was right on time and finished right on time. He made the effort to explain what he had done and supported it with pictures. Because of his attention to detail, I am certain our unit will operate much more efficiently. Way to go, Daymon!

Dan was very knowledgeable and professional. We really appreciate the fast response of coming to our home for an estimate and was able to install the new AC and new furnace the next day. The installation crew was very considerate, friendly and knowledgeable. Renee at the office was very friendly and helpful as well. Thank you everyone that took the time to make the installation possible in such a short turn around time. We would highly recommend Kettle Moraine heating and air conditioning. A+

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.

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.
