Joe Marx

Luke was very courteous and answered our questions

Ray Willoughby

Bill is very professional and provides the highest quality service. He explains what he is doing and informs me of any issues he may find and what is needed to correct. I specifically request Bill because of this. He is a real asset to Kettle Moraine.

Robert Nakielski

Brian B from Kettle Moraine heating was prompt on calling me after i submitted an after hours call. He stopped at our home in a very reasonable time. He was very polite and answer all of our questions. We were up and running in a very short time. I would recomend Kettle Moraine to others. I like the business model that makes them customer driven. Great job

Melissa Polcen

We used Kettle Moraine Heating and Air for radon mitigation. Easiest process! We emailed to schedule for an estimate. The response was quick, the service rep was friendly, knowledgeable and explained everything. The installation team was prompt, friendly, super clean, and completed everything with no interruption to our day. Highly recommend this team!

Ronald Vaughan

Extremely professional. Replaced my water heater same day! Will use their services again.

Heather Thiele

I highly reccomend Kettle Morraine Heating & Cooling. I'm on a limited income, my house is old & the wiring is questionable so repairs are always complicated. They helped me get my heat going for a reasonable price, they informed me of several options, they talked me through each step & helped me to understand the whole process. I've never had a more pleasant experience with a service tech- he was super conscientious & did follow up. When initially calling, everyone I spoke to, (receptionist, service desk, manager & schedulers) was professional & kind. Not only did I get a call from the tech when he was on his way, but I got a txt from the office also with his photo. Will definitely use them again

Gary Janetzke

Tyler did a great job servicing my furnace and humidifier. He was prompt and professional which is not unusual for Kettle Moraine Heating. I wouldn't use any other company. Five stars for sure.

Jeanne Krajewski

From estimator, Cole to installation experts Mike and Joe, office Sherry and Katy and electricians Jake, Joshua and others..... new furnace and A/C installed in record time and explained the features. Each employee professional, courteous and clearly knew their business. Highly recommend this company!

Deb Geary

Cory did a great job. Excellent service

Ally Cetnarowski

Jacob was on time, very pleasant demeanor and explained everything thoroughly. Highly recommend him for future service

Robert O'Keefe

Dylan Rohde from Kettle Moraine Heating is the best HVAC tech we have ever had in our home. He went “outside the box” very thoughtfully and discovered the sources of three issues that have plagued us and had not been accurately diagnosed by our previous HVAC firm - which would have cost us at least $1500 to repair. He fixed all 3 at NO COST to us! Wow.

David Hammen

Our church Immanuel UCC in West Bend has a Peace of Mind package. We had out fall maintenance scheduled for Tuesday the 26th of November starting between 8-10:00 AM. Jeremy and Damian showed up at 8:00 as scheduled and began their task of servicing our 5 furnaces and 2 boilers. Everything went off without a hitch. There was one repair done on one boiler, but it was no surprise because we were made aware of the issue that last time, they inspected that boiler. Jeremy and Damian were completed with all the inspections by 2:30. They were super to work with and very courteous to everyone they interacted with.

Nicholas Beadell

Thanks for showing up on short notice and being patient going over all our options. Great job!

Jaclyn Anderson

Awesome fast customer service sherri and sales tech guy Matt was so prompt professional and left us so happy. Great experience!

Dan Las

Our experience with Patrick from Kettle Moraine Heating was very good. He was prompt, did a great inspection of the furnace. Very good service would highly recommend him.

Kathleen C.

I was referred to Kettle Moraine thru Home Depot store referral program last yr. After interviewing several HVAC companies, including the one I had used since 1995, I chose to purchase both furnaces from Kettle Moraine Heating & Cooling. Great experience with the install and I just finished the annual maintenance and cleaning service. The technician was on time, very professional, reviewed my expectations before starting the work and explained everything to me afterwards. I am very happy and grateful to Home Depot for introducing me to Kettle Moraine Heating & Cooling. I also learned today that KM has other services such as radon mitigation, and plumbing. I like the idea of calling one trustworthy company for maintenance projects so that is a plus as well.

Thomaspaintss

Ron Erdmier

Fantastic service, see ya in July.Thank you, Ron Erdmier

Victoria Witt

It was great that the company sent us a text ahead of time that the technician was on the way with a picture and Information on his favorite sports teams. He was on time And very respectful of property. Everything. looked beautiful when he was done. Meaning the stuff he Installed looked great and to code and everything was clean. He was politeand informative. All-around great experience. The salesman was nice and friendly, and all the staff that I worked with. This install has helped us decide that this company is our new go to for any maintenance.

Lisa Weinzatl

Everything was done quickly and professionally. Would definitely recommend again.

Andrew Kale

We had Brett out as a requested technician to inspect our furnace in preparation for the winter ahead. He confirmed all was functioning properly and gave me a heads up that the filter would need to be replaced in the not too distant future.He is personable and I will request him again for inspection of our air conditioner before summer rolls around.

Andrea Ortin

Very thorough, with clear explanation of services needed!

Jean Garrity Murphy

I had the BEST experience! After four weeks of another company “trying” to fix the furnace, I finally called Kettle Moraine Heating. Tim came over within an hour of my call, and the furnaces & AC units were installed two days later. Matt and his team were professional, knowledgeable and hard working. I’m so happy I went with Kettle Moraine!

Tommy Murray

I've spent the majority of my life in some form of customer service so I tend to set the bar high. Well this company has truly exceeded my expectations. Professional, Curteous and Informative are just a few words that come to mind. Kettle Moraine you have a customer for life.

Kristine Reger

Jacob was friendly, efficient and answered all my questions.

Harmony Stencil

The whole experience working with Kettle Moraine was great! Making the appointment to get a new furnace/AC/humidifier/air filter system was quick and easy. Getting texts with the worker's pictures was reassuring and thoughtful. The crew worked fast and were polite and considerate. And the price was very reasonable. We have found a company that we will continue to work with for future home projects!

Brian Delfosse

Heater went out on weekend evening (of course) and needed to get somebody here. Damyon showed up within about 45 min from my call. Polite and diagnosed my problem while keeping me informed during the process.

Lisa Rowland

I’ve had nothing but excellent experiences with the Kettle Moraine Heating and Air Cconditioning staff. Patrick was here for semi-annual maintenance. Patrick was, as always, professional, and friendly. He was thorough, informative, and answered all of my questions and his services were greatly appreciated.

Nick P

From what I was told by my mom they did a very good job.they where everything you'd expect nice friendly and cleaned up like they where never here walked my mom through everything that I need to know when I got home from work. I won't leave out the sales guy who worked with me while I was at work going over everything. I had 3 quotes done and sat down with my mom and said OK so who do we trust because I was at work and everything my mom has said about them has been good and I am glad we went with them from start to finish If your in the market I would choose them again and they will be doing all my equipment check ups from here on out

Bob Kelly

Owner placed restrictive pest screens on the intake and exhaust vents off the furnace outside the condo resulting in a back pressure trigger and cycling of the furnace.

Barb Bruns

Jim Bialk came to tune up my 1 year old furnace and taught me so much about the furnace and especially about the best filters to use. I learned so much from him. You can tell he likes his work skill and is happy to take the time to educate a homeowner. Terrific job 👏 👍 👌 J8m is a real asset to the field. Kudos!

Rob Freuler

Benjamin R. did several updates for us, (kitchen sink, faucet, and dishwasher venting), bathrooms (toilets), and new utility sink, faucet, and cleaned up the PVC water pipes with copper in the basement. Everything was done to perfection! Highly recommend him and Kettle Moraine Plumbing Services.
