Ryan and his team did an awesome job installing a new hvac system in my duplex. They were very respectful of my property and cleaned up everything before they left. Ryan also answered every question that I had during the installation process. My entire experience in dealing with Kettle Morain, beginning with getting information about a new hvac system from Scott Holpfer to the timely appointment and install process was flawless. I'm very happy that I chose Kettle Moraine to get my new system installed. Excellent people to work with.

The team was on time. Very courteous and polite. Explained everything to me.

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.

Fast, friendly, helpful HVAC service.

Our furnace was not working on a Sunday evening. I called Kettle Moraine Heating's 24/7 helpline and we troubleshooted on the phone. On Monday morning they sent a super helpful technician, Brandon, who replaced the 'smart hub' and installed a new device. He carefully explained lower and higher cost solutions before I decided on the fix. He also shared a few helpful tips on system maintenance.

Very satisfied with the timely and thorough service!

They offered a good high efficiency system at a good price AND had 0% financing. The install was done the next day in less than 7 hours. Everything about the company is very professional and customer service focused.

Brent did a great job. Very friendly and thorough. And put boots blankets on when entering the house

Travus, at Costco, was great in helping us set the appointment. Cole, our salesperson, was great in helping us understand our options, and Pete and his crew were great in installation and cleanup.

Highly recommend Kettle Moraine. Thier technicians and admin team are very professional, highly skilled and respectful towards my mother and I as customers. They will take the time to explain the system if you ask them to. They installed a complete HVAC furnace and duct work system, Aprilaire humidity and HEPA air systems. Beware the Aprilare does need more servicing. Whenever we had a question, they all have been quick to call back and quick to make ajustments to the various installations they placed in my mothers home. When we pointed out a concern, they were quick to ensure everything was in order. Great!

Helped set up the app

Matt was very thorough. Took photos of the process and shared them with me after the furnace tune up was completed

I purchased a Lennox high efficient furnace through Costco with Kettle Moraine Heating & Cooling as the contractor. From the initial visit and proposals to scheduling and installing my new furnace, the process was very smooth. Good communication on the Costco process (from KM) and timely updates on day of install when technicians would be arriving. Install completed on a warm November day, but looking forward to colder days with peace of mind that my new furnace will keep me warm — and be more efficient! Great job by Dan H. and team; they were patient with answering any questions or concerns I asked about. I would recommend KM!

Hey, Brandon. Thank you so much for the great service on my furnace. Your honesty really impressed me. Don’t get that too much anymore. I was also impressed when you explained all the details of my new thermostat. I will definitely recommend Kettle Moraine Heating.

Excellent price and service. Love the professionalism and way they kept our house and carpet clean!

Thank you so much from the phone call to the installation furnace and a/c, nothing but friendly and customer service was outstanding! 6 individuals from start to finish were amazing I would suggest them if you ever need assistance. Our normal schedule appointment was until Nov 18th. We literally had no heat and not very many options and I received a phone saying they would be here today I was so thankful.
Happy Thanksgiving to all of you and your family. Our family is very thoughtful for your quickness and thoughtful help in a situation that was needed asap! TORRES FAMILY 👪 ❣

I had my Furnace tuned up today by from Kettle Moraine Heating and Cooling. As usual the the process was performed and did an outstanding job. Thanks Kettle Moraine Heating and Cooling.

Highly recommend

Really impressed with the folks from Kettle Moraine. They installed our furnace nearly 10 years ago, came in today to do some repairs and inspection. Luke was a fantastic technician, very knowledgeable and helpful. Mark from KM was able to take a concern I had and turn it into a positive experience. Looking forward to doing the monthly plan for maintenance and inspection of our ac and furnace.

Professional, strong expertise and engaging.

You did an excellent job. Explained everything to me and informed me about possible problems in the future.I would highly recommend you.

Thank you Dylan from Kettle Moraine Heat & Air. Once again I received exceptional, courteous and cost effective service!

Brandon was very professional & did an excellent job.

Great install and amazing service

On 11/5 David T came out to address a stuck sink stopper in my MBR sink and adjust the stopper in my powder room bathroom as well. He was also able to assist me complete winterizing my (3) hose bibs. Awesome service again and a helpful tip on how to keep the sink stoppers working properly since they are rarely used to hold water in the sink.

Today 10/14/25 was the first time Kettle Moraine was ever at my home. David T from the plumbing division professionally diagnosed my issue. I appreciated that he showed me the size of the worn flush valve compared to the new one he would be installing. He explained the valve’s function to insure I understood that this was causing the periodic ghost flushes I was hearing. I loved that he took the time to explain the function and assure me this little rubber item being replaced would alleviate my issue.

Then he went to my kitchen and replaced a Kohler duo strainer where the bronze skim peel had came off. Kohler had given me a replacement duo strainer since the strainer was damaged within in a week of a prior install. David suggested to help insure the bronze finish not peeling off as quickly this time I should turn on the cold water first not dump hot boiling water into the colander and then turning on the cold water to rinse the pasta off like I did when I saw the peel missing after making pasta. Again, I love these helpful tips!!

It was a fabulous first experience he went above and beyond to fix the items on my repair list!!

Even better, I’m excited and looking forward to having my first furnace tuned up on 12/8 with Kettle Moraine!!

I signed up for the annual furnace and AC tuneup plan. Thank you again to Matt in the main office for making my first experience on the initial phone call incredible !! He explained the different levels of plans and I was able to choose the one I thought best fit my needs. 🙌🏻

Since then I’ve spoke to multiple people in the office and everyone has upbeat and friendly.

Aaron Radliff and his team from Kettle Moriane Heating installed our new HVAC system yesterday.

They removed our old system installed our new Lennox system explained things as they work, including filter changes and how to use our new thermostat & HVAC system. They cleaned up everything before leaving the house cleaner than when they arrived.

Thanks for a job well done.

Greg is wonderful. He looks over everything very thoroughly and informs me of the status. I like that I’m learning about my HVAC system.

Great team! Professional, courteous, knowledgeable. Went above and beyond. Highly recommend.

Just had a new Furnace install today 11/4/2025 and Kevin B and his partner were great, Professional and install only took 5 hrs Thank you. The furnace works great my house is cozy warm.

Tune up went as expected.

Matt was delayed due to issues at prior job. I received advance phone calls from Matt and the office. Matt did a thorough job of servicing the furnace. While servicing the furnace, he explained what he was doing and why. Very impressive! I will be requesting Matt on all future service calls.

Working with Damyon was great, efficient, and quick. He did an outstanding job.

The technician did a very thorough job of checking our furnace. Very efficient, very courteous.

Jeremy did a fantastic job in servicing my Furnace.

Absolutely the best and easiest furnace replacement ever. The old Lennox lasted for 25 years so it was time. The technicians, Ryan and assistant, were courteous, efficient and informative. Great folks overall at Kettle Morraine HVAC. Will definitely use them again for service and supplies.

New furnace and A/C installation. Great crew who walked me through new equipment functions and new features and upkeep tips. Crew was respectful of home and swept the mechanical room after installing.

Very friendly and professional installer,and great price compared to the other estimates I received.

Dylan Rohde from Kettle Moraine serviced my furnace today and did a great job. He checked and cleaned all components for proper operation. I reckoned this young man and company!

Brian our technician called prior to arrival and stated he would be arriving on time. He introduced himself, put on plastic boot coverings. He evaluated the 20 year old furnace explaining what he would be doing and got right to work. Brian explained what he was doing as the work progressed and took the time to address each of my questions. Brian did a thorough job of cleaning everything and explained in detail why he was taking things apart to clean and took pictures to make sure everything was put back together properly. On finishing he vacuumed around the furnace and made sure I was satisfied with the work. Brian thanked us for choosing KM Heating and Cooling and verified that I was on the cheddar A/C maintenance in spring. A job well done.

Kettle Moraine is an excellent HVAC company. Their technician Jacob is a very engaging and knowledgeable young man. I recommend this company and technician

Wendy of Kettle Moraine Heating set up an appointment for the same day that we called. Jacob, the technician, came 30 minutes earlier than originally expected, worked diligently and expertly, was very friendly, completed all work to full satisfaction quickly and for the price quoted. I strongly recommend this business and their employees.

Prompt, efficient, very complete. Gave full explanation of service and items needing correction for 10 year old air conditioning system. Completed the work in a timely measure and the total price was very reasonable. Great job overall.

Jacob did a great job. When we called they said they were busy but said they would come the day we called (Thursday) but ended up not coming until Monday.

The technician seemed well informed informed me of several things I didn’t know, and just overall seemed like an experienced technician which I like to have

Aaron went above and beyond in explaining the problem and offering different alternatives etc. His professionalism was superb and unparalleled
