Did a great job installing my 100 amp panel and outlet for an EV charger. Highly recommend.

They did a great job!

Had a great experience having Matthew Wolf of Kettle Moraine come around and complete servicing and maintenance on our AC unit. Matthew gave me some great education and I felt very well looked after. Kettle Moraine offers a peace of mind package that we pay monthly for ongoing servicing.

We had a new furnace installed in 2023 and a new air conditioner in 2024. We signed up for the annual "Maintenance Agreement". Well, we are 100% satisfied with the quality of workmanship, professionalism, prompt service, friendly attitude and excellent products sold.
We have never needed a service call on either machines to date. The annual maintenance is such an outstanding offer. It gives you peace of mind that your investment is being taken care of. I would love to recognize Ray Seeber, our technician for his outstanding quality of work. He was so informative, patient and respectful. Thank you Ray, we look forward to seeing you again.
Kettle Moraine, you are certainly the BEST!!!!

Doug was a joy to work with during the fall HVAC tune-up. He explained what he was doing, answered my questions, offered suggestions for regular upkeep and diligently problem solved to get everything working optimally. Thanks!

Update: Spring 2023
The HVAC system was running well all year! Doug came back and performed annual maintenance, cleaning and checking the system. Easy to schedule and work with Kettle Moraine.

Update Update: Spring 2024
Consistent maintenance pays off as small problems are caught and fixed in May before they become a HVAC crisis in July or January. Service personnel are consistently professional. Thank you Kettle Moraine!

Update Summer 2025
Jeremy was super efficient in tuning up the AC units at our duplex. Scheduling service for AC, furnace and hot water tanks was a breeze. Thank you!

September 2025
Dan and crew installed new AC units. They were on time and efficient as they removed the old ACs, explained how they were recycled, and then got the new units in place. They answered questions along the way and gave tips on how to keep the AC running efficiently. I especially appreciate the clear instructions troubleshooting shooting tips that they posted on the blower units.

After receiving a quote from a different company we asked Kettle Moraine Heating and AC to provide a second opinion. Damyon came over and was great, he explained everything to me and outlined what needed to be done to fix our furnace. We will now be going to Kettle Moraine Heating & AC for our HVAC needs.

Excellent customer service as always! Patrick is a great technician who communicates effectively, is on time, pays close attention to any concerns we have and quickly resolves things.

Had the privilege of working with Paul. He gave me a heads up when he was on his way and showed up ready to go. He was very personable and professional. He knew his stuff and gave some good advice. He was very efficient and made sure to bring anything noteworthy to my attention during the maintenance on my furnace. I would gladly work with him and the team at Kettle Moraine Heating again!

The Service Technician (Dylan) was prompt, thorough and professional in completing the fall tune up of my furnace. He showed me pictures to explain his work along with possible needs down the road. It was a thoroughly pleasant experience!

Dylan was very efficient and professional. He explained everything he checked and was very informative.

Dylan was great to work with when we had issues with our thermostat. He explained things well, came up with a quick solution, and had things working within an hour. We really appreciate his help!

Very friendly service. Very efficient. Answered all our questions. Went through each system with us thoroughly after installation.

This was Matt’s second visit to my home. He arrived as scheduled, and I appreciated his call saying he was on his way. Matt explained what he would be doing, what he did, took photos as proof and did an excellent job. Thank you Kettle Morraine.

Luke was a great guy got a lot of information from him on my oil furnace he was so knowledgeable on it did a great job on my oil furnace took care of everything like it was his own

Dylan did a very thorough test and tune-up of my furnace and explained all his findings very detailed and understandable. Lots of photos. He also serviced our AC earlier this year and is very thorough.

Damyon was excellent. He looked at our unit and told us exactly what was wrong and what it would take to repair it, he also was able to tell us exactly how much it would cost to repair it. He even went to the extreme as to tell us how to save money. He was great. Thanks Damyon!

Jacob J. Visited to complete our AC maintenance. He did a great job, showed up on time and was extremely communicative. We would highly recommend Kettle Moraine Heating and Cooling!!

Ryan and his crew along with the electrician did an excellent job for us. The installation of our new AC was done neatly and the workmanship is to be admired. They were a pleasure to work with.

Aaron was polite, thorough in expertise manner, and very informative!

The technician was friendly, very knowledgeable, and great communication.

We had another company come out and quote us $7000 for work on our furnace, that was only six years old. When Kettle Moraine Heating came out they found the only problem was our vents were blocked. They saved us $7000. They are honest and reasonably priced, they were lifesaver. Thank you so much! Brandon Renteria was very nice, helpful and friendly.

Thoroughly inspected and ensured all of the system was working correctly. Took time to discuss at the end and ensure I was clear on details.

JJ was outstanding and was patient as he explained the mechanics of what he was doing and was very conscious as to what I required and kept it within my budget. I highly recommend this company.

I had excellent service done by Brandon R. He was very knowledgeable and his work was efficient! Very nice and friendly, very pleased by this company and Brandon’s performance! Will recommend kettle moraine to friends amd family!! Thanks!!
