Regan, Joe, Mason, and Lucas did an excellent job on my furnace and AC install. Not only that, but they were great at communicating updates throughout the process, very detail-oriented when it came to installing the equipment, conscientious and clean, and ensured that we were happy with every aspect of the work. I also appreciated that they took care in providing a tutorial on how to use the equipment and information on essential preventative maintenance like air filter and humidifier cartridge replacement to ensure mt furnace and AC last for decades.

Explained in detail what he was doing and had fair and honest recommendations for the furnace.

Did a great job!

Good team of guys. Went right to work.

Kettle Moraine Heating and Air Conditioning was truly exceptional in every way. Miguel came out to provide quotes for repairing our existing furnace and replacing it. He was knowledgeable, friendly and never made us feel pressured. We ultimately replaced our 11 year old furnace with a new Lennox, and I only wish we had known about KM when we bought our previous furnace. They offered a fair price for a two stage furnace, and we decided to enroll in their maintenance program as well. Before leaving, Miguel even took the time to bring up our garbage cans. That thoughtful gesture went well beyond what we’re accustomed to. Jordan handled the installation and was professional, incredibly hardworking and took the time to chat with me about the Brewers before he left. The installation looks fantastic, and the furnace is whisper quiet and runs much less often than our old one. If you need your furnace or air conditioner repaired or replaced, I strongly recommend giving KM a call. They also installed our central air, and we’ve been very pleased with it. I make a point of not speaking poorly about other local businesses, but the difference between how my wife and I were treated by KM and our experience elsewhere was eye opening. From the initial visit through installation, we felt valued and respected. After such a wonderful experience, we’re KM Heating and Air customers for life.

We had our annual furnace check and all is well. Andrew was friendly and did his thing efficiently. Very happy with the experience

Fast friendly service at a good price

Install of new central air and furnace

Great job. Informed us of what was needed.

Matt was very thorough explained everything he did. He took the time to answer my questions with knowledge and experience.

Kettle marine heating and air-conditioning has been great to work with. Extremely responsive. Great communication. Great team with people that work for them.

KM Heating saved the day! My 28 yr old furnace needed to be replaced just as the weather turned colder. I had a quote from another heating company that made me cry at the cost. KM provided an equal option and better named product for a significantly lower price. Less than 18 hrs later, they arrived to install. They covered my floors to ensure no mess, were extremely pleasant and knowledgeable. Showed me all the features and answered all questions patiently. Truly wonderful to work with! Shout out to Craig, Justin and Lucas. Highly recommend KM Heating and Cooling.

Always have had a good experience with Kettle Moraine HVAC. Quality work!

Lucus did a great job tuning up our generac home generator. He was very knowledgeable and was done in no time. Hope he comes on our next tuneup.

Very Thorough and patient with customer questions

On time, efficient and friendly.

Brian did an exceptional job for us! It was super professional and provided great direction on the work that needed to be done and then took us through everything at the end and answered all questions and provided some recommendations as well!! A+ guy!!

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.

Professional n courteous

Awesome service

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.

Matt was very professional & helpful. So glad we changed to KMH.

Cory was helpful with answering my questions and giving information.
