What Our Customers Say

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!

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

Jacob was outstanding! He took the time to clearly explain everything that was going on with our current A/C unit and walked us through all of our options. He was knowledgeable, professional and never made us feel pressured. Thank you Jacob for your excellent customer service.

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!

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.
