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!!

The service was great. The technician was excellent, but the repairs was so minor the price seem high

The technicians at Kettle Moraine are knowledgeable, friendly, and honest. I appreciate how they explain what they're doing and answer my questions.

Pete and his team were prompt, courteous and efficient. Kept me aware of what they were doing, and reviewed important changes from my previous system

Brandon was awesome and patient. He answered all my questions earnestly and provided good counsel. Only 4 vs 5 only because I asked him to look at the internal unit which revealed a deeper symptom and the likely culprit (blower moter) of our problem.

Jeremy was great! He explained what he was doing and why. He was friendly yet professional.

Paul with Kettle Moraine was absolutely fantastic. He was able to identify a problem that our usual HVAC servicer was unable to on multiple occasions. He was friendly, professional and very thorough. I can not be any happier with the services we received. Thank you Paul!!!!!

Timely service with excellent communication for arrival time and cost.

Very good work and great guys always friendly thanks

Some of the hottest weather on record in Wisconsin and our air conditioner failed. Paul came out and within an hour we knew the problem and how to fix it and when the repair would be done and how much was estimated.👍

A good job

On time for estimate.

Excellent service from Dustin.

Dylon was great!!!

Jordan and his crew did an excellent job! Efficient and thorough! Cleaned up after and answered all of my questions!!!

Nice job

Derek and everyone that installed my new AC did great work. They were able to install it quickly!

Fast to respond, highly qualified technicians. Kettle Moraine Heating and Cooling did a great job getting us back up and running in the summer heat. Ask for Jacob. He was a great tech. Knowledge, experienced, and great to talk with.

They were wonderful from the start. Called on a Monday they came out the next day. And installed the new furnace/air conditioner that Friday. Why because they knew how hot it was going to get on the weekend. Very professional, great customer service and we’re so nice. I highly recommend them for all your needs with HVAC, Plumbing and Electrical.

Elian was very professional, helpful and friendly. I loved that he used shoe covers when it my house.

Kettle Moraine’s annual maintenance service agreement has been outstanding for several years. We have been fortunate to have Matthew out to do the annual A/C maintenance. Kettle Moraine and especially Matthew are extremely professional, courteous and attentive to every detail. Highly Recommended.

Responded fast & did good work.
