Fast and efficient replacement of our HVAC system. Very knowledgeable and courteous.

The crew was no polite, friendly and professional. They cleaned up every thing prior to leaving. They explained everything and answered all of our questions. Definitely would recommend Kettle Moraine Heating!

Absolutely the best experience I’ve ever had with a subcontractor. Everyone was nice and professional. Follow up was impressive as well.

Luke is always my go-to guy for furnace/AC work with Kettle Moraine. He remembers my house/system and its history and makes the appointments seamless. Highly recommend Luke or anyone else from Kettle Moraine Heating & Air Conditioning.

Brett fixed my ac that is in the ceiling of my kitchen. Working over my kitchen island is a challenge in itself . He protected everything with a movers blanket which I appreciated. He also had me listen to the unit to make sure it’s sound level after the repair was perfect.

Not sure how old the water heater is exactly, but Jess & Ethan, went the extra mile to flush it out & complete the job. Also gave me an estimate on a replacement as well, when Iam ready to do it😄

Had a PM done on our 2 year old furnace. The technician Matt was very knowledgeable and explained all the work he was going to complete prior to starting the job. He was very thorough and professional. Also he saved me some money on including a future PM on our A/C unit.
A job well done.
PM on our 25 year old A/C unit was done by Brandon at the end of May. He thoroughly went over everything, made adjustments and explained what he found. Ended up replacing the original contact board on the unit.

I’ve been using Kettle Moraine Heating & Cooling for about 6 years now, and they continue to exceed expectations every time. Most recently, I had a complete HVAC installation done, and the entire experience was outstanding from start to finish.

The technicians arrived right on time, and I really appreciated their app updates letting me know exactly when they would arrive. The crew was friendly, courteous, professional, and treated my home with great care. They covered everything up, kept the work area clean, and made the entire process stress-free.

A special thank you to Dustin, the lead technician I’ve worked with for years. He has helped me on multiple occasions and has always been honest, upfront, knowledgeable, and extremely dependable. It’s hard to find people like that these days.

If you’re looking for a trustworthy heating and air conditioning company that truly cares about their customers, Kettle Moraine Heating & Cooling is absolutely the company to call. Highly recommend!

JJ did a great job completing the annual maintenance on my furnace. He was prompt, courteous, and answered my questions in a way I understood.

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.

Always honest, prompt, excellent service.

Patrick did a great job. He explained my system condition and we discussed some future options. Eric, who is doing an apprenticeship work Kettle Moraine, was also present and seemed engaged in the call. I really appreciate how KM provides opportunities to young people. Keep up the good work

Jacob service tech. Friendly.

Paul did a very nice job with my HVAC service today. As always Kettle Moraine Heating & Air Conditioning is a great company with their products and servicing.

Great company. Very fair and responsive. I highly recommend. Great warranty work.

Kettle Moraine is great, they've always been professional and timely. I've had my entire HVAC system replaced with ductwork in my older home, it was a huge help to actually balance the temperature in the house. They also do plumbing, which is great! The solutions they've provided with both teams has greatly improved the look and feel in my house. I will be using them as my main contact for any of the stuff listed below from here on out.

Brandon was very professional. Everything is working great.

Very Thorough and patient with customer questions

Wyatt was very friendly and went above and beyond to make sure the problem was fixed. Greatly appreciated all his help.

Very informative technician. Matt took the time to answer all my questions and provided great service.

Experience service. Was able to get my install of the furnace and ac within a week of signing contract. Awesome installers. Great work!

Jonathan came out and was able to diagnose the problem within 30 minutes. He was very kind, and professional. He took the time to explain the issues. Would definitely use again.

Our technician Patrick Gorman did a great job educating me about my system. He was polite and professional. We had a great experience with him and his company.

Craig from Kettle Moraine heating and coong was here with Trevor and Justin to install our new furnace and air conditioning unit. I would highly recommend this company and crew for a job well done! Very courteous and professional on time both starting the project and finishing! Very clean and neat, put down runners and cleaned up everything!! Craig also went over all of the installation details including the thermostat before they left! Great "Home Town" company! Awesome people!

Matt Wolf took extra time to explain what work was done. He was enthusiastic & informative.

Miguel was awesome! KM is always great to work with!!

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

The most professional installers I have ever encountered. Kept us informed on every step of the install. Made sure everything was covered yet they still wore booties while working inside the house.
Highly recommend Kettle Moraine Heating and cooling.
