Matt Wolf did maintenance checkup on my furnace and air conditioner.
I was amazed at the time he took taking things apart cleaning and checking.
He spent 4 hours checking both units.
He really was detailed oriented.

Arrived on time. Did the work and cleaned up afterwards. Very professional.

Matthew did a great job for us. You’re lucky to have somebody that’s confident and mature. Hopefully you take really good care of him.

Annual furnace tune up completed today. Couldn’t have been more happy with our professional, friendly and knowledgeable technician, Aaron Maze! Thank you Kettle Moraine heating for having such efficient staff. Thank you, Aaron for a job well done!

Jeremy was very diligent in our service today. Very clean, efficient and he explained everything
We would have him again. 5 stars!!!!

Amazingly professional installers, knowledgeable, and a wonderful experience overall.

Lucas and Austin did their work efficiently and professionally. They installed a tankless water heater and water softener. They reviewed all aspects of the installation with me, confirmed my understanding and cleaned up the work area leaving little evidence they had been there. No complaints whatsoever and I highly recommend them and KMHAC.

We cannot recommend Kettle Moraine any higher! We had a complete replacement of our furnace and air-conditioning unit. From our first contact with salesman Dan F, and throughout the entire process, we were absolutely floored with not only the pricing but the fantastic service. We had our furnace repaired twice this last year by two other companies and it was a horrible experience. This was the exact opposite.

Dylan handle both my furnaces and AC and always does a great job. I have three systems in my Home, and he deals with all of them quickly and efficiently

Zach and Trevor arrived to do an underground in conduit install to replace old wiring that failed to our outdoor pond area. The team did a great job and the pond pumps and aerators are back up and running.

Jacob B was the service tech for our yearly AC tune-up. He called me 20 minutes before he got here to let me know he was coming. He stayed focused and quickly checked everything inside and outside our house, and changed the air filter. Then he told us what he found, both verbally and in writing, which was great. I totally recommend Kettle Moraine Heating & A/C if you need this kind of service!

Mathew was very professional and explained everything he was doing.

Mitch does great work, we trust him with our plumbing needs.

Matt is great to work with! Very nice person and very thorough! We greatly appreciate the great Service!

We happened to stumble upon this business and I am so thankful I did. From the initial phone call to setting up an initial visit, to the actual installation and delivery—everyone was fantastic. Dane took the time to explain the entire quote for the AC mini Split units and the additional sub panel need. Dustin was fantastic in coordinating everything. Dan G, was working on the installation both days. Everyone was SO kind, and knowledgeable. We are very happy with the investment of the mini splits and will continue to utilize Kettle Moraine Heating & AC.

The hot water heater install went smoothly. Mitch was courteous and respectful. Answered all my question with ease. Very knowledgeable about the product. I would highly recommend Mitch and Kettle Moraine plumbing service.

Brent was awesome, very knowledgeable, extremely thorough and friendly. We are tremendously happy with our service call. We highly recommend him to anyone who may need repairs

Miguel was professional, knowledgeable and courteous, he took the time to explain what is going on with the AC system and made recommendations for preventative maintenance to potentially add life to system.

Great technician with a really friendly outlook! Matt did a great job!!

Scott our sales person was so informative and professional. He provided us with great information so to make our decision. The crew that came to do the installation was professional, easy to work with and did an amazing job. The whole process went so smoothly. We appreciated how easy it was to work with them on this major purchase for our home

Wonderful service. Very professional and helpful. Will continue doing business with them!

Great job as always. Highly recommend requesting Jeremy.

Wonderful experience. From the quoting process to the service, everything went well. The installers, Jacob and Faith, were courteous, explained the installation and cleaned up when completed. Great communication throughout the process. Will definitely be using Kettle Moraine HVAC again.

Patrick is exceptional. Technically superb and a genuinely good guy. 👍👍👍👍

The crew did a great job with the new ac retrofit. We both were impressed by their set up, and they answered and explained all our questions. Great experience, and we will certainly recommend the company to all our friends

Kevin and Mike did a great job removing the old HVAC system and explaining to me how the new one will be installed. They removed all the refuse and left the space as they found it. A week later they returned with a crew to install the new equipment. We needed the delay to finish some construction before the new furnace and AC went in and they made it happen. The parameters of the install were not as straightforward as simply replacing the units. The furnace exhaust had to be rerouted through a different portion of the basement and the AC unit had to be moved closer to the house. To say they did a great job is an understatement. The crew was completely professional, got everything placed as we discussed and were thorough about removing debris. They explained everything they had done and left us with a completely upgraded system that was greatly appreciated as the temps soared to 90 the next day. I would, and have already, highly recommend Kettle Moraine for heating and AC. If you are a Costco member, the shop card incentive makes a big difference when comparing prices, as well.

Jacob and team did a fantastic job, very professional with all team members. Explained what was going to be done and went over throughout the installation. Pleased my wife and I decided to go with Kettle Moranie Heating and AC for our new ac and furnace. We have been using them for the last 25+ years and always had good service.
Thanks for the quality work and install.

Jacob was awesome. Diagnosed and fixed the problem right away.

Always professional. Great service. New water heater is great! (Old one made it 36 plus yrs) BENJAMIN is super to.work with
Very happy with Kettle Morraine

Have been using Kettle Moriane for years...annual tune ups, as well as new A/C and furnace. Great company...no complaints. Jim has been our tech for several years now...very polite, professional, courteous, and personable. Wouldn't have any other company handle our A/C and furnace needs.

Elian and trainee Manny did a thorough job to determine the issue with my furnace. Very cordial and pleasant to work with. Nice job!

Brent from Kettle Morraine heating and cooling was easy going and professional. We are very pleased with the work he performed.

I have never had a bad experience with KMHAC. From first call to final follow up, everything has always gone according to their clear communication and transparency. The install crew, led by Pete, on my last project was in and out and walked me through all the details of what they did and why they did what they did. No surprises with this company.

Dylan was knowledgeable and helpful

Miguel did a great job trouble shoot my concerns and even made adjustment for cooling efficiency. Great service and very professional.

Arrived on time and was extremely thorough and conscientious. We have utilized KMHAC for the past 8 years and are extremely happy with their serci e

Bill and partner were very professional...easily explained diffence in furnaces and quick! And Dave the electrician took his time to make sure all was right and up to code. Very satisfied!

We had a great experience with Kettle Moraine Heating & Air Conditioning. Sam was amazing during the evaluation process! Very knowledgeable, helpful, and took the time to answer all of our questions.

Jordan and his installation team were fantastic. They were professional, efficient, and did a phenomenal job with the installation. Everything went smoothly from start to finish.

We highly recommend Kettle Moraine Heating & Air Conditioning!

Brent brings many skills and natural abilities to the table! He is personable; he is smart; he is a quick thinker- quick diagnoser- and quick problem solver; he is also just quick. I'm not sure if he actually walks, he kind of lightly sprints up and down the stairs, and in and out of the house to get the job done. He is also a low pressure salesman.

Quick, personable, friendly and efficient! We love Jacob!!

Brian and his OTJT assistant Eric, we're able to confirm the AC unit was low on refrigerant. The price for R22 I saw on line was $219.00 for 5 lbs. The fellows spent a good amount of time checking the unit and restoring operation. They added1.25 lbs of R22 refrigerant to the system and verified supply air temperature and return air temperature as well as low and high pressure system readings. The service call charge was waived, since the previous technician service did not address low refrigerant concern along with other missed items.
