Thermostat had failed while on vacation. Called K-M Heating and Miguel was here in less than 2 hours. Outstanding, competent and prompt service.

Matthew showed up on time, from Kettle Moraine Heating &Air. He was very informative. Conscientious about his job , I feel like the maintenance he did for me is going to make my unit last a lot longer.

Patrick Gorman, provided annual A/C
maintenance and service. Patrick is very professional and friendly. He answers all my questions and informs me if there are any items that need attention. I am grateful for Patrick!

Positive experience with a very good employee, knews his stuff, did the job well in and in a timely manner.

Arrived at the start of the appointment window and answered all of my questions.

Had AC installed a few months ago and I am very pleased with my overall experience. Pete was amazing with the initial quote meeting and the work done a few days later by Dan and Joshua was very good. They not only installed the AC, but also added an outlet outside and fixed my exhaust pipes on the back of the house. AC has been working great ever since. I would use this company again and recommend it to others.

Extremely nice people to work with.
Highly recommend them for sales and services

KETTLE MORAINE, installed my new Lenox furnace in 2016. The install crew was very efficient and completed the install in 1 day. They have performed yearly maintenance service ever since. Brian has been our tech for several years now. He is very personable, knowlegable, focused, and does a great job. He has been proactive in replacing parts known to be problematic or on recall. Always cleans up when done. This year 2024 Aron provided outstanding service PM my heating and Ac systems. Early this October my thermostat froze up and would not work. Aron returned solved the problem and showed me how to reboot it again so I could fix it myself. Thanks Aron and thanks to Kettlemorane Heating and air conditioning for the geat service for the last 9 years.

My HVAC system is now 10 yrs old just had my annual service. Miles was the tech. Mile was very thorough and covered all the bases. He was very personable and explained things very well.

Our technician was awesome!

Matthew was very pleasant explained everything thoroughly was very pleased

Dylan R -arrived on time, was very professional, explain things to me and was upfront with pricing. I would recommend him.

Had them install a new furnace/AC last December. Finally needed to turn in the AC on last week and it was making a metallic buzzing noise. I called to get it looked at and a service tech was here in about 20 minutes, he diagnosed the problem in about five minutes and only needed 10 minutes to fix it. [manufacturer's issue, two pieces of metal were touching that should not have been, causing a vibration]. Works fine now.

They were very helpful and explained everything to us. Very smooth process and didn’t have to wait much. Also really good plans if you’re on budget or can’t pay it all in one

Matt was very detailed in the maintenance/checkup of the furnace.

We had them install a generator for us and are very impressed with their level of customer care and availability! Thank you!

Technician was great at explaining his services, why they are important and how to save money on our heating and cooling bill.

They guys were very informative and very courteous. From getting an estimate to the installation . Will recommend!

Outstanding service, as usual. Very friendly plumber, Mitch, who showed me everything he did. Used authentic Kohler replacement parts, and other high-quality materials. Recommend highly.

On time, pleasant and efficient

Elian Rivera was a pleasure to deal with. Very knowledgeable and efficient. Signed up for maintenance contract - looking forward to continuing with Kettle Moraine.

I’m very pleased with the job that Khamya did for my seasonal a.c. inspection. Very thorough and answered all my questions.

Thank you, Patrick Gorman for your expertise. Appreciate your answers to questions and respect for wildlife nearby.

Kettle Moraine Heating and Cooling always has friendly and honest service every time they’ve come out.

Did a great job replacing our furnace and AC unit including clean up! Appreciate that they took time to answer my questions.

Jacob Johnson was very thorough in his inspection, analysis, and cleaning of the air conditioning unit. He explained what he was working on as he performed his duties which I very much appreciated. I gladly rate him 5 stars.

They guys did a great job today. We appreciate your work.

Covered warranty service, great service

He did a great job explaining how the system works and seemed to do a thorough check.

Nice guy did wonderful work and explained everything to me and wife effective and efficiently. Hopefully, he can come back when we need more work done

The most professional team of experts ever! Done in half a day with an entirely new central air system. They even took the dirt they cleaned off the floor with them ! HIGHLY RECOMMEND!

Riker, Faith, Miguel, and Joshua did an excellent job installing our new furnace and AC unit. The craftsmanship with their individual trade was incredible. The line set, electrical, gas line, exhaust, and ductwork was neat, clean and orderly.

When they finished they left the space in excellent condition. I’m appreciative of their hard work, friendliness, and for treating our home like their own.

The service we received from Kettle Moraine Heating and AC was TOP NOTCH!
We have a 60 year old AC unit that konked out on us, and the first company I called said they wouldn't even attempt to fix it. Kettle Moraine said they would looked at it, but they couldn't guarantee any parts. Dylan came out and looked it over, found the problem, but unfortunately it would cost thousands to fix.
He was extremely professional, wore shoe coverings in the house, showed us pictures of what the problem was. He explained in detail where the issues were, but in terms that we could understand.
I really appreciate that he even attempted to fix our unit rather than just telling us right off the bat that we would have to replace.
In the end, we are going to have an estimate done to see how much a new system is going to run us, but I'm still extremely thankful for Dylan and all the staff that helped us with our AC unit.

Both technicians were professional, timely and knowledgeable. Our hone was left better than before they came and non of my plants were disturbed when they stalked our new unit. Family values and fast service. Thank you Kettel.

Honest, hard workers did a great job with taking out the old furnace and AC, replacing and explaining!

Very professional and amicable. Answered all my questions and concerns.

Great service from KM Heating on my hvac repair. Tech was courteous and took the time to explain, answer my questions and provide sensible advice.

Jacob was friendly and efficient and did a great job with our needed maintenance.

Very knowledgeable and polite. Would recommend!

Jeremy was very knowledgeable and helpful when he dealt with our A/C issue. He got us up and running the same day. We appreciate his professionalism and responsiveness!!
