Love this company! Professional, knowledgeable and friendly technicians. Prices are reasonable for the quality service. Technician Brian is the best!
I'm happy with the furnace installation. The two young men did excellent work.
Kettle Morain provides consistent good quality services. The technicians are good and excellent in what they do. My last service for tune up was with Matthew and he is really a great technician. You can rely on them!
Dylan Rohde did an excellent job of explaining & performing a furnace tune up for us today! Also gave us an estimate on a better filtration system that we will seriously consider. Dylan was prompt,Knowledgeable & very courteous! Kettle MoraineIs fortunate to have Dylan as an employee!
They did such an amazing job!! The guys were friendly and knowledgable. Im very happy with my boiler and hot water heater
Excellent work and clearly explained the HVAC condition and every parameter tested.
Technician Aaron Blakely did a great job diagnosing a problem with the humidifier, and a very thorough job cleaning and doing maintenance on the furnace. Very professional.
My technician Luke took care of two of our furnaces today. You won’t find a more professional HVAC technician anywhere. I should know, I am a74 year old general contractor, now retired, I have seen them all. I hope kettle moraine realizes what an asset they have in Luke!. Thanks Luke for another great job. Kirk Magill

Really thorough workKnowledgeable and explained everything clearlyWill definitely call them next time I need work
Been in our home almost 35 years. Couple months ago, I saw water on the floor under our washing machine. Decided to replace the washer. Went to the basement to look above where the laundry room water supply lines come up through the floor and saw an electrical junction box under the supply lines. Checking the box, there were mineral deposits on the cover, suggesting water leak in the past. Figuring electricity and water don't mix too well, I called KM Heating & A/C's electrical division to have someone come out to move the junction box, as our sump pump is plugged into a socket on the junction box. Josh was out on April 19 to do the repair. He chose to move the box over a foot away from the water supply line and managed to get the job done quickly and efficiently. Wiring was added and new conduit with connectors were put in. Couldn't be happier to know the new junction box won't get wet, spark up, or cause a fire. New box and conduit can be seen in the picture.Update: July 25, 2024 - we have two central air conditioning units that needed to be checked to make sure they were working as they should. I went to our “go-to” crew at Kettle Moraine Heating and Cooling. Brent was assigned to the task. He did a thorough check of both systems and reset a blower motor on one. He arrived on time and worked quickly and efficiently. We are looking forward to his return in October to do a check on our two furnaces. Thanks, Brent and KM Heating and Cooling.UPDATE: 10/14/2024: In contrast to “global warming”, our part of Wisconsin is now into “global cooling”. To get ready for colder weather, we had KM Heating and Cooling do a check and tuneup of both furnaces. Patrick was the guy who drew the short straw and came out to check the furnaces. The furnaces are six years old and had no servicing done since they were installed. Good thing Patrick checked them over and explained that both furnaces were not delivering the correct gas pressure and those were adjusted to correct pressure. Igniter sensors needed to be cleaned up or those could have failed and the furnace wouldn’t start. It took Patrick about 45 minutes per furnace and ran $268 with tax. With an early and long winter expected this year, it was good money spent to insure heat when we need it. Thanks much, Patrick, and KM Heating and Cooling.UPDATE: December 16, 2024: We needed to have the wiring checked in a ceiling fan light and the bulb sockets needed to be replaced too. The usual option is to just buy another lamp to wire into the ceiling fan. I looked at thousands and nothing appeared to put enough light directly on the kitchen table like our current one did. The bulb sockets were made of Bakelite plastic that deteriorated over the years due to heat from incandescent bulbs we used to use. I replaced the sockets once and spent most of the day on a ladder to do it. Too old to do that anymore. KM Heating & Cooling electrical division said they could check out the light and possibly salvage it for us. Joseph came over and figured out the problem pretty quickly. He changed out the plastic bulb sockets with ceramic versions and the light has 4 arms on it. Joseph took each arm off, found the wiring showed signs of wear, so he rewired the entire lamp fixture. In about 90 minutes, the job was done and the light was back in service again. Joseph was very efficient and precise in his work. When we need HVAC or electrical service, no one else will be touching our house but Kettle Moraine HVAC/Electrical. Thanks, Joseph !!
Was on time and very knowledgeable of the installation. They were very efficient.
The team was professional, helpful and cleaned up after they were finished. Overall it was a great experience. Thanks for such prompt service also!
Great Guy! Awesome work! Happily explained what he was doing and what was good and not so good with my furnace and what needed to be done to make sure my equipment was safe and able to do the job effectively! Will definitely be using Kettle Moraine HVAC to update my house!
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.
Great service and friendly staff
Efficient and effective service. Luke was thorough with pertinent explanations and gave a couple other easy ideas to troubleshoot in the event the fixes he made were not the answer. Would highly recommend them for service.
We have used kettle moraine a few times and are always very happy with the service we receive! Electrician Jake A. is fantastic - efficient and super friendly. Would definitely recommend!
Everyone at KM H&AC were great. Timur was a great advisor, walking me through every option by comparing it to common things to make it relatable and easily understandable. Manny and the install team were like a well oiled machine. The work was phenomenal while being respectful of the house/property, cleaning up in depth, and walking us through the operation and finished work. Highly recommend them!
Damyon from Kettle Moraine Heating just cleaned my furnace, and he was very professional and thorough. When he finished, he put everything back where it belonged in my little condo furnace room. I couldn’t have asked for a better job!Deanna SowllesPewaukee
Brian was very personable and respectful of our home by taking the time to put on protective booties over his shoes, much appreciated. He explained everything he was going to do as well as what he accomplished and found. He observed a problem with the furnace exhaust and appropriately fixed it. Highly recommend KMHAC.
Aaron was greatTold me what I needed to know to start making an informed choice of optionsThanks Aaron
My Generac generators service light came on and I called Kettle Moraine H& AC. They call and came out within a few hours. Ian was my technician and was outstanding!!!
