What Our Customers Say

A huge thank you to Kettle Moraine and Brian for coming out to repair my AC on such short notice.
Our AC went out while it was 90° outside and they had someone out within an hour of us calling. We were out of town and had someone house sitting, they made this such an easy process while we were handling this away from home. I am so appreciative of the service that we received from this company. Would definitely recommend.

Jeremy came out late on a week night and worked in the dark and heat to correct material issues with our AC system. He did an excellent job and was meticulous in testing the entire system to make sure everything was working well.
Brandon was excellent! Central air went out, they had him come out the same day, only to find we need a whole new unit. Great news, they are installing tomorrow due to health concerns for my 92 year old Mom; that’s a company that shows they care about more than just $’s. Brandon was very knowledgeable, helpful and kind! I love working with Kettle Moraine; good, long term family business. I love their community involvement as well as their commitment to solve your problem(s). Wouldn’t go anywhere else!

Luke Lutzke came to my house today to work on my AC. He was absolutely amazing with his work and was very professional explaining what my needs are with a new AC unit.

Dan and the rest of the team were amazing. They came to install a new AC and furnace, working in the attic at unreasonable temperatures during the heatwave to ensure we have comfortable home temperatures moving forward. The entire team was friendly and very professional. They answered all of my questions and tested both systems to ensure they were properly set up. They truly went the extra mile to ensure we were happy with the job. I couldn't have asked for a better team to work in my home.

The team installed mini split in my small house. They worked fast, didn't turn off the power to the house so I had my window A/C running the whole time and was comfortable at 90 F outside. They came on time and cleaned up after themselves. Overall it took them about 5 hours to complete the job. Very satisfied customer here.

We recently purchased our home a couple years ago and were told to expect to have to replace the whole system soon due to age. That said, recently our system failed so we called Kettle Moraine. They did a full HVAC system inspection and found that not only was the original system was not installed properly, it wasn't even designed correctly in the first place. The KM team (Tim, Aaron, Dave, Riker, Neil and Trevor) took the time to redesign and retrofit the entire thing. The installation looks great. Highly recommend!

Paul rhoroughly inspected the AC unit, found the problem and was very helpful. Thank you! Looking forward to finally fix it for good.
I switched to Kettle Marine heating and Air Conditioning because the contractor that installed my furnace in 2012 has gone downhill horribly with their service in the last two years. Jeremy was outstanding. I wish I'd been using him all this time. He pointed out so many things that the previous contractor should have done and didn't do. I feel so much better knowing he will be taken care of my air-conditioning in my furnace because his knowledge is excellent

Paul Barker and his co-worker from Kettle Moraine Heating and Cooling installed an efficient Lennox furnace that required unexpected work to be done that was not included in the initial estimate. Even though it took significantly more time to complete, they honored their quoted cost. They left the basement cleaner than they found it after the installation was completed. If you choose Kettle Moraine for any HVAC project, I encourage you to request Paul for your technician.

Outstanding communication from making the appointment and confirmation! The service day appt was very prompt.
Very clean, our service provider put protective booties in to walk in house. Our system has been checked up annually! Kettle Morraine installed furnace and AC several years ago. Super professional group!
I also like the service of furnace and AC check ups bundled together for one price!

Quick and easy AC tune up. Technician was professional. Only criticism is the cost of the peace of mind package… it’s really gone up over the years.

Had an issue with our aging AC unit with hard starting as well as delayed starting on very hot days. Dylan came by and performed a diagnosis, replacing a couple of parts and fixed up some wiring and now this '92 AC unit can chug along for another year, maybe two? Great work and service from these guys at kettle moraine heating and cooling.

Kettle Moraine A/C service was terrific. The tech Luke explained everything so clearly that when he left I was comfortable with final purchase. Kettle Moraine is lucky to have him as an employee
