Michael Schmidt

Kettle Moraine Heating & Air Conditioning came highly recommended by friends and co-workers and now I see why. Great communication about my appointment (Sarah) and from our repair man (Brett). He was very friendly, efficient, and took time to explain everything that was inspected and also fixed the clog that was causing condensation water to backup into our furnace. I was very impressed and will be using them if needed in the future. 5 stars and I would highly recommend!

Michael Hautzinger

We found Kettle Moraine through a special offer through Costco. After comparing the Costco, Kettle Moraine Heating & Air Conditioning stood out as the best choice for our home. The estimate was accurate and they've stood by the quoted price. The office staff was great about scheduling the work. Matthew lead his crew on the installation, which was timely, efficient & professional. I was given an orientation to the new HVAC system and thermostat. All questions were answered clearly. Warranty paperwork and the inspection were explained in detail. The crew cleaned up after their work was complete. Job well done Kettle Moraine Heating & Air!

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.

Mary Russart

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

Barbara Christus

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.

Mike Hamachek

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!

John Rood

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.

Lori Kraemer

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

Christopher Wittmann

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.

Marlene

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!

Bill Klug

Helped set up the app

Todd Firer

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

Debbie Kolb

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!

Carol Wills

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.

Eric Kujawa

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

Shanna Torres

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 👪 ❣

Steven Spak
