Good installation team very friendly and perfessional! Thank you!
Excellent and friendly service.
Matt explained what was wrong with the current unit, showed me the parts that failed. With the unit being 28-30 years old I asked for an estimate for replacement which he provided. Great service from Matt and the two women I talked to in the office. I will recommend the company to friends and neighbors.
Excellent. Very informative. Technicians were very professional and nice. I felt comfortable asking questions and they answered them that I understood.
Friendly and knowledgeable. Told us everything that was needed and fixed what he could. We need filters for the Furnace. His advice was very helpful. Thanks Brian
Matt Wolf texted and called and arrived on time. Very pleasant person who answered all my questions and was very professional. I will request him for my annual furnace an AC check ups. I’m very happy with the service.
They are always helpful, friendly, & professional!
Nick did a great job installing the water heater. Very happy with the work.
We are hoping that they can find the parts so the job can be completed
Mike was Fantastic as we're all 4 of the Team that were out today. What does not surprise me because I have been familiar with KM Heating and AC for years( never used they used to be in my neighborhood), however Whenever I would call with a question they would always be willing to answer. This time being , without a c at 90°+ and 85!° indoors Each and every person I talk to at the offiwe're absolutely fantastic almost like talking to my best friend. Why would anyone think of going anywhere else?
Matt is very professional, knowledgeable and helpful. Matt did an excellent job with our annual A/C tune up. Thanks Matt we appreciate your great service!

Brain from kettle moraine heating is very friendly and does his job with care and perfection.
Mike was awesome. Friendly, helpful, efficient. I called with a non emergency AC issue at 7pm and asked them to fit me in when available and they had my AC fixed by 9am the next day.
Matt F. did a fantastic job getting our A/C back up and running in very short order. He was professional and seemed quite knowledgeable.
We had a generator installed today and were very pleased with all of the installers that came to our house. They were very polite, nice and left everything clean.
Matt was wonderful. He did exactly what was needed, was quick, and even wore booties to keep the floor clean. Excellent attitude and great service.
We were referred to Kettle Moraine by a friend a few years ago and love them! They have installed a new AC for us and worked very hard to get us the best bang for our buck without trying to oversell us on things. We also get the peace of mind package every year, and just had our AC tune up today. Our technician was Matthew and he was very kind and knowledgeable! 10/10 would recommend
Brent did an exceptional job identifying the problem and resolution
Patrick G/Kettle Moraine Heating & A/C was extremely professional, knowledgable and friendly during my seasonal maintenance service! I have always had great service with Kettle Moraine over the years and would highly recommend them!
We purchased a new home, only to find when we moved in (June) that the AC wasn't working. Kettle Moraine Heating and Air Conditioning was recommended. After a short wait, Brent arrived ready to help. He quickly determined the issue and informed us that our current system was at the end of its 22 year life. He helped us price out a system we could afford and even got our old system working until the new one could be installed. We couldn't be more pleased with Brent and with KMHAC! Thank you so much!
Paul was fantastic and thorough! He helped convey his experience in practical terms and was open to sharing each step of his process to be fully transparent. He was pleasant to work with and the perfect mix of professional and personable. We applaud his proactive assessments, logical approach, consideration for our circumstances safe practices while he was in our home.
I have been using kettle moraine for many years. They offer great service and Tyler was very helpful and friendly. I would also like to compliment your customer service area especially Kim who was very and helpful. I wasn’t receiving your return calls or voicemail and she worked with me and was very patient. Your company deserves 5 stars
Great company, wonderful service, knowledgeable technician!!! Highly recommend and very pleased with their service!
My new AC works GREAT ! I can't believe how QUITE it is. I was actually standing next to the AC unit talking to the service tech's and didn't realize the AC was running. My experience with Kettle Moraine was EXCELLENT 👍 THANKS EVERYBODY
Paul arrived on time, and gave us an honest and reasonable assessment of our air conditioning issues. Very personable. He also spotted a problem with a vent near our water heater, that could have been potentially troublesome. Recommend this company to anyone who needs heating cooling, and plumbing work.
Just wanted to thank Mark for his time explaining our options. I know that we have made the right decision and that we will continue to work with the company in the future. Thanks
KM always has expert staff who are knowledgeable and personable.
On time, very polite. Very happy with work and explanation of work done when finished.
We had the best experience with Matt from Kettle Moraine. Not only was he professional, he also took customer service to the next level by explaining the A/C system to us and showing us how to operate it. We are so please with this top notch platinum service and would highly recommend Matt and Kettle Moraine for your cooling and heating needs. Thanks Matt
Great service, on time and on point.
Our A/C on a recently purchased house in Lake Geneva quit working. They were able to send a tech out the same day. Paul Purdy, the tech resolved the issue quickly and inexpensively. It was a simple fix and we weren’t told that we needed additional parts or equipment. Very honest tech and company!
You guys were on time, professional & a pleasure to have service our home. You all went the extra mile and we appreciate it.
