The installation crew for our HVAC were knowledgeable , professional , and friendly. They kept focus on the work to be done until the job was finished. They also left their work environment cleaner than they found it. They kept us informed as they worked, and made sure we knew how to use the system before they left. They made sure the exhaust pipes looked as good as they functioned on the outside of our house. Great job Matt, Mason and Joe!

Brandon has done an excellent job for a humidifier installation.
Brian was on time, analyzed the issue and made a speedy repair. Brian did some quick research and determined that the problem part was covered under warranty.

Matthew and the team of 4 from Kettle Moraine Heating and AC did an outstanding, professional job replacing my 16 year old furnace which developed pin holes in the heat exchanger. Discovery of the pin holes emphasizes the importance of annual furnace inspections for this potentially lethal condition.

I have used their services since 2014 when they installed my new furnace and air conditioning unit. They are always informative and professional. My most recent service was the installation of a new thermostat. My service technician was Bill B. This was not the first time he has done service at my home. He is always on time, courteous, professional, and explains everything he is doing. I am very thankful he is part of their team. Thank you Bill and Kettle Moraine.

Outstanding service, as usual. Very friendly plumber, Mitch, who showed me everything he did. Used authentic Kohler replacement parts, and other high-quality materials. Recommend highly.

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.
