Kurt Leapley

Brett Zielski came to find out why our furnace was not working. He did a diagnostic and found that there were bugs in the burners and the injectors were dirty. It was an easy fix, and Brett was quick, efficient, and the repair was very cost effective. We were very satisfied with the service!

Sue Alger

Great service. We called at 8am because our hot water heater wasn't working. By 1pm we had our new hot water heater and hot water by 1:30pm. Plus the old heater was installed by another company but under warranty and they were able to install with only installation charges. Great folks to work with from office to technicians.

Gretchen Miller

Damyon was super helpful. He took his time to check everything over thoroughly. We very much appreciated his help, knowledge, and professionalism!

Cheryl

Very Prompt service! Brett arrived earlier than expected! He checked everything out thoroughly on our Furnace. He explained the diagnostics to us so we could understand. He was very knowledgeable and answered all our questions. We look forward to continuing our business with Kettle Moraine Heating.

ROBERT BUKOWSKI

Everyone I worked with was professional and very friendly. From sales to the installers, electricians to the Women on the phone. I highly recommend Kettle Moraine Heating and Air. Special shoutout to the salesman and the two mechanical guys. You were enjoyable to work with and I am 100% satisfied with the new furnace.

Aaron Moore

The team @KM Heating & Air are very professional and go above and beyond to ensure all needs are met. The desk staff is very courteous and the technicians are very knowledgeable. Brett Zielski diagnosed the problem immediately and came back a few days later to handle the issues. We will definitely be working with this company again.

Kimberly Melka

The KM team did it again! Another ⭐️⭐️⭐️⭐️⭐️ 5-star experience with them! David T was our master plumber who installed our new toilet and vanity/faucet - and all new quarter turn shut off valves. Thank you David for your professionalism and attention to detail!

chris kroeninger

Ryan and the entire crew did an exceptional job installing our furnace and air conditioning system. Ryan did a great job explaining the new thermostat and other equipment maintenance and accessories. The whole team was professional and courteous.

Patricia Utech Smith

Greg was on time, kept me in the know with the details of what was happening and how long it would take. He knew what time I had to leave and was respectful of my time. He was courteous and friendly. He explained things in a way I could understand without talking down to me. He is welcome to come back to our home the next time!

Randy Biedenbender

kevin kieweg

Excellent job very prompt and professional.Knew what he was doing I would recommend This company to do Radon installation 100%

Matt Dorfler

Very helpful and quick, quality work

Mattie Gorman

Aaron and his team were professional, courteous, and efficient while they were installing a furnace and AC in my home a few weeks ago. The furnace has been working great and the crew didn’t complain once about spending several hours in a crawlspace. Hopefully I won’t need a new furnace anytime soon, but if I did, I’d call them again.

Karen Freitag

The tech texted and called to give a time of arrival. He put on boot covers while in the house. It was nice that he asked if I had any questions or concerns before starting the tune-up. When he was finished, he explained what he checked and the items that were replaced on the humidifier. The visit was about an hour. The tech, Jacob, was very polite and personable. I would recommend Kettle Moriane Heating and Cooling.

Max Costello

Friendly technician, arrived early in the time window.

Kristen Olson

I am amazed. After a nightmare of an issue lasting over 2 months with an unethical competitor, I contacted Kettle Moraine Heating in the wee hours of the morning on a Monday, while dealing with the last straw of no reliable heat. Tuesday, they arrived to give me a very reasonable estimate, and the install was completed by 2 pm on Wednesday. I wish I could give more than 5 stars, this team is phenomenal.

zpomms

Prompt, professional and they know what they are doing. Highly recommend!
