Brent was very polite and thorough working on our AC units. We initially started out with just our yearly maintenance, but found out another problem with a newer unit, which was under warranty and repaired at no cost to us.

Regarding the installation process of two furnaces and an AC unit: excellent. Manny and his crew arrived on time, were respectful of the property and involved me in the decision-making process in regard to where pipes would go to ensure that the plan did not interfere with my use of the areas affected. Questions answered well. All members of the team were pleasant. Very satisfied. Quote process prior to installation was good. No comments yet on the Lennox products themselves since they haven’t been used yet. But so far, very happy with Kettle Moraine Heating and Cooling.

Cory was great, up front and honest on what I could do to correct my plumbing issues, rather than trying to sell me something I didn't need. Kettle Moraine will be my go to plumbing contractor.

New to Kettle Moraine HVAC this year. I was very happy with our visit with Greg W for our annual service appointment this fall. Greg was very knowledgeable and explained and went through everything he was doing and saw. I was super impressed when he even took inventory of our entire HAVC system for their records. Maintenance of everything in my home is important to me and it was bittersweet for me when the service that I used for literally my whole life retired. I am thrilled with our new relationship with Kettle Moraine HVAC and feel confident that I am in great hands! PS - Big fan of your blog!

Great work by a great group of guys from Kettle Moraine Heating and Cooling. Replaced our old 30 plus year old Lenox HVAC system with a new Lenox system.

During a routine maintenance air conditioner check on Tuesday by Patrick, I told him that recently during two very hot days, our 3 year old air conditioner was not cooling as quickly as it usually did. Upon checking things out, Patrick found that our condenser had an unusual issue that was causing it not to cool properly, and was also posing a danger in its current condition. Because of the unusual issue, Patrick’s manager Dustin also came to our house, and they determined that the condenser fan needed to be totally replaced. (Thankfully the air conditioner was still under warranty!)It sounded like it would take until early next week for the fan to be available. To our surprise, less than 48 hours later, Patrick returned with the new part, and got our air conditioner working again.Patrick was very professional, knowledgeable, courteous, friendly, and prompt. I highly recommend him!!

I had a fantastic experience with this Kettle Morraine H & AC! The team was friendly, professional, and highly skilled.

I've been trusting Kettle Moraine H&AC to keep my now 22 year old system running in top condition by making sure furnace and ac are serviced near the beginning of the season. Always a stellar job. Tyler Bump is friendly and efficient. Much appreciated.

Jeremy arrived at the beginning of the arrival window, very professional and was fully aware of the discussions that I had had with the office staff regarding our service needs. The maintenance service was very thorough and Jeremy conveyed the results in an understandable and professional manner … no upselling.

Kettle Moraine heating and cooling (and plumbing!) To the rescue- again! They definitely went above and beyond. They didn’t give up on my problem when others did. They were able to fix the work of another plumber who left me in a bind. They were honest and fair in pricing. I am 100% pleased with the work done and highly recommend this business. This is the 3rd time I’ve used them and the technicians have always been professional and the work is exceptional!! You will not be disappointed.

The staff and crew at Kettle Moraine Heating & Air Conditioning were amazing!! Before committing to a new AC unit they were able to answer all our questions. The crew arrived right on time and were very clean and professional. Once installed, we were shown the new unit and our questions were again answered. This is a top-notch company!!
