Brian was very professional and was great at explaining what our options were when it came to replacing our furnace. I would recommend him to my own family and friends anytime!

Jim was on time and did a great job.Very helpful.I will look forward to future visits..Thank You.
KM Heating always does a professional job servicing customers. The communication throughout the process is excellent.
Seems like everything done that I asked you do in correcting outlets. Again Thanks
Jeremy is always a pleasure to interact with. He’s prompt on his arrival time and is very thorough when explaining the preventative maintenance performed or why a new part is needed. I’ve always had a nice experience working with Kettle Moraine Heating. I highly recommend using them for service.
Great job by everyone at Kettle Moraine Heating & AC. I had a new furnace installed & wiring for AC that is being installed in the spring. The office personnel were extremely helpful in setting up my estimate appointment & installation dates.My sales person Ian was very knowledgeable when he was at my home for the estimate. He explained the different options, answered all my questions and didn’t try to upsell me on the units or other “recommended” fixes to air ducts and other parts.The furnace installers and electricians did a fantastic job on the installation. They were on time, got right to work getting the job done quickly so I’d have heat in my home again. They walked me around the unit when they were done. Showing me everything and explaining owner maintenance jobs to do on my particular unit. Showed me the basics of the new Smart Thermostat. Cleaned everything up at the end of the install and very friendly and willing to answer questions.Again, fantastic job by everyone at Kettle Moraine Heating.
Brett did a great job of telling us what was needed to update our furnace. He was friendly, on time and professional. Our problem was resolved quickly, glad to have this companies contact whenever their services are needed. The support staff/customer service also always does a great job communicating in a very timely manner. Great company to work with.
Luke was awesome, he was very knowledgeable and transparent. He worked quickly to diagnose and troubleshoot. He got my heat up and running quickly and gave me advice on upgrading from an old furnace and a/c system.
Kettle Moraine Heating and Air Conditioning is a great company. Professional, knowledgeable and very responsive. I use them for all my heating and ac needs
Matt was phenomenal and explains things thoroughly and really takes pride and ownership in his work! I highly recommend him and Kettle Moraine!
It has been so nice working with Kettle Moraine Heating and Air Conditioning. Damyon came to diagnose and inspect our old noisy furnace. He took his time and reviewed all our options and recommendations on a Friday afternoon. We ended up deciding on a new furnace, which they quickly had in stock and ready to install by Monday morning. Aaron, Tucker and Harvey did a fantastic job installing the new one and walked us through the install. We had some siding crack during the install which they offered to cover and had it fixed right away at no extra costs. Their estimate matched the final invoice and was easy to read. Overall we had a great experience and will be choosing them for our yearly maintenance on our furnace and A/C. I would highly recommend Kettle Moraine Heating and Air Conditioning to my friends and family!
Luke Lutzke was extremely helpful in identifying the outdated humidifier at my new house and quoted exactly what i needed to get it working the way it should. Highly recommend!
Excellent workmanship and great workers. Install was stress free. Thanks KM.
We had a friendly and professional visit from Kurt. Continue to use kettle moraine h/c..
Outstanding work, if I have an ac/heating issue he is the tech you want.
Everything went great and Jeremy was awesome
Called with no hot water at 8am, has new water heater by 2pm. Response was quick, professional, Pete and Noah knew their stuff and the replacement went quickly.Would definitely recommend to others!!
Awesome crew, very nice and very clean.highly recommend.
The last day of the year I woke to the house being 55 degrees. I called for support. The office staff was kind and considerate. They immediately contacted someone to check out my furnace. Detlef was understanding and helpful. Answered all my questions. Fortunately he was able to fix the problem. Appreciate the service.
Excellent service!!! Thanks Patrick 🤗
I had a fantastic experience with Kettle Moraine Heating. They were punctual, arriving exactly when they said they would. Their attention to detail was impressive, and they explained everything clearly throughout the process. Luke was highly communicative, professional, and demonstrated excellent technical expertise. I’m confident in their work and would highly recommend them!
Matt Wolf did a very good job tuning my furnace and gave me valuable recommendations.
Very professional, but before I do 5 stars, I want to get a second opinion on required work. Very friendly, explained everything. Quotes provided quickly.
Matthew and the rest of the KM team provided friendly, professional and quality service including a same-day visit to keep our heat on!
They were very quick and efficient. They also were very knowledgeable about the A/C system that is in my residence. They are very reasonably priced. I would highly recommend them to anyone.
Brent will take care of you
Always professional. Great service. New water heater is great! (Old one made it 36 plus yrs) BENJAMIN is super to.work withVery happy with Kettle Morraine
Our 35 years old furnace died on us.Glad we called Kettle Moraine Heating and cooling. Great communication, great people, and fast response time.
Humidifier installed by Jacob. Very polite and informative. Initially there was a slight issue with getting the correct humidifier installed but that was resolved quickly and Jacob was able to return the same week with the best fitting unit.It’s only been a half hour and I can already feel the difference in the air quality. Since this is day one only I can’t really provide a complete review on the unit, the Aprilaire 700, but will post an update once we have used it for a bit.Overall, at this point, the service was great.
Just had a new furnace installed and from start to finish Kettle Moraine was extremely friendly, helpful, and honest. From the estimator who came out to the technicians I would recommend them 10/10 we will definitely be doing any future work that we can with them!
Matt W did a great job tuning up our furnaces. He has good knowledge and answers all question.
Prompt response from dispatch. Tech arrived quickly. Problem resolved
Had a new Lennox & AC installed yesterday. Guys showed up right on time, did a great job and actually completed ahead of schedule. Even helped with setup of new Smart thermostat as well. Could've done a little better job with cleanup though. Overall happy with their work.
From the sales guy, finance lady and install guys everyone was extremely friendly, knowledgeable. I would highly recommend Kettle Moraine Heating for all needs. Thank You to everyone who got us heat!
Great service by Tyler!
