What Our Customers Say

We had received recommendations for repairs from another company after an inspection of our aging boiler. Given that their estimate was for multiple thousands of dollars (combined with some high pressure sales tactics), we solicited other bids for the work. Andrew from Kettle Moraine was very knowledgeable and did a great job explaining our (somewhat complicated) situation, as well as detailing different approaches we might take. It was clear that the focus was on being honest and transparent, and this did save us a lot of money in the short run. When it's time to replace the boiler, we won't hesitate to go to Kettle Moraine for the work.

I had a great experience with Kettle Moraine HVAC! Joshua handled the electrical work for my new A/C installation and did an excellent job. He was professional, knowledgeable, and made sure everything was done right. I also want to give a shoutout to Pete and Damien, who handled the A/C installation. They were professional, hardworking, and made the entire process go smoothly. Overall, a great experience with the whole team. I really appreciate their quality work and would highly recommend Kettle Moraine HVAC to anyone needing heating or cooling services!

Overall, we’ve had great service with Kettle Moraine over the past nine years. However, the recent change in service technicians has been a little disappointing, as the service hasn’t quite met the standard we were accustomed to with our previous technician.

Brandon was fantastic. He diagnosed the boiler problem fast and had the parts on hand. He even took time to teach me on how things worked since I’ve only had forced air before this house. Couldn’t be happier with the service.

Luke was very professional, knowledgeable and did a great job tuning up and cleaning out our air conditioner. We are worry free with the Peace of mind program that covers both heating and air conditioning maintenance for the year.

Kevin and his partner did excellent work and were very polite and considerate about my house.
I bought a house recently and my furnace suddenly went out. Jeremy from Kettle Moraine Heating came out and did a great job! He was very professional and knowledgeable and quickly diagnosed and fixed the issue. The pricing was very fair and transparent and I got really helpful advice about ongoing maintenance. I will absolutely use this company again in the figure, highly recommend!

Wonderful from start to finish. We worked with many local companies getting quotes and didn’t feel as comfortable as we did when we finally reached out to Kettle Moraine. Professional, knowledgeable and easy to work with. Quick install, great employees and exceptional service.

They always do great work at competitive prices and the people they send are very professional, skilled at their craft and incredibly easy going and friendly. These are people you can trust. The last 2 or maybe 3 appointments I had Jon from Kettle Moraine. What a great guy. He's a smart, skilled professional that is a pleasure to have in your home. + When he leaves everything is out away and clean. No messes after his work is complete.

All KM employees were very professional and Detail orientated, during a reasonably tough project and install. Looks real good. I would recommend this company to others in need of their service.
