I enjoy having Kettle Moraine HVAC come out to do the maintenance each year. They do fantastic work and are very helpful. I have never had a bad experience with Kettle Moraine and would recommend them for any HVAC need.
Jacob was friendly, helpful and professional. Highly recommend!
Excellent and efficient service. Competitive cost!
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. 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!
The guys were on time, worked efficiently, courteous and cleaned up beautifully. Would highly recommend KETTLE MORAINE HEATING for all heating and air conditioning needs.
I had a tankless water heater serviced and flushed. The technician, Jess T, was knowledgeable and professional and did a nice job. Thank you!
Luke was great! Very communicative and punctual. Quickly assessed the issue and was clear in his proposed fixes. I’d highly recommend!
I just had the A-Team from Kettle Moraine Heating and Air Conditioning over today to install a new heating unit and AC unit. ALEC, Zack, Zack, and Dan did an outstanding job with the total installation! They all were very nice, professional, and knowledgeable! They were very helpful in answering all my questions and explaining everything I needed to know! I couldn’t ask for a better crew doing the job! Quality company and work crew! Thanks for your service!
First time Matthew maintained the furnace. He answered all questions thoroughly, gave good pointers and was fun to talk with.
The technician Mat was prompt, efficient and professional, he communicated with me through each step of the tuneup and reviewed his work at the conclusion with comments and photos of the furnace
Great Service
Amazing experience! Received a furnace tune-up. Was very affordable and they did great work.
Awesome servicr e!
Kettle Moraine Heating, Cooling, Plumbing and Electrical is the type of company I have been searching for. They are a one stop shop, and are efficient, competitively priced, not “salesie yet service oriented. Thank you for all you do!
I now have 3 furnaces installed in my home and my rental property they do outstanding work and are absolutely customer service oriented
Jim was very good at explaining what he was doing when asked. He was also on time and very polite. I would recommend asking for him again!!
Patrick was very professional, answering any questions that I had and explained everything that he did. Great job!

The professional team showed up on time and were very courteous to take all precautions so as to not damage anything while moving equipment…
Luke was great. Very knowledgable and professional. He took care of the issues very quickly and gave information on a future install I requested. I have used them for the past six years and have never been disappointed.
Very professional, excellent work

Our original Lennox furnace was 49 years old, so we definitely wanted another one.
Furnace stopped working overnight. Called Kettle Moraine and had a technician at y place in less than an hour on a Saturday.
Problem was quickly diagnosed - all my options discussed and next thing you know we're heating the house again.
My furnace went out on Sunday morning. They got back to me in less than 1 hour and had someone out right away. Needed a new furnace and they had it all installed and ready before noon on the next day. Customer service is absolutely amazing!!!! Never went to them before and they treated me like family. Also offered several finance options. So easy to work with and again I can't say enough about the amazing customer service. Definitely recommend kettle moraine heating to anyone.
The guys were absolutely great!! They were informative, knowledgeable and did a great job!! I would highly recommend them and Kettle Moraine Heating & Cooling.
Our installers were great!! Knowledgeable and very professional,
Took more precautions to protect my floor than me.. the install is very professional in appearance and they took the time to explain everything in detail.. in all I would highly recommend Kettle Maraine to anybody!!!
Thanks!!
Dylan did a great job. Very professional, was kind enough to answer my questions as he was working on the furnace. A very nice person who was very knowledgeable and fixed the problem quickly. I appreciate the quick response and his great kindness and knowledge. Excellent experience. Thank you Dylan.
Jeremy was able to troubleshoot the problem immediately. He thoroughly explained the problem and had pictures of the issue to show me. He provided a solution to replace the parts or replace the furnace. I recommend Kettle Moraine to anyone else with a furnace!
This was an annual furnace maintenance visit, not a repair. Jim was very nice and efficient. I like the new security measure of receiving a photo in advance of his arrival. The cost includes A/C and water heater maintenance.
They notified me they were coming. They were polite, answered my questions, finished the job on time, and cleaned up after themselves. I didn’t even know they were in my house. I would recommend them to anyone looking for a new furnace.
Called yesterday because I was having issues with my furnace. Damyon came this morning and found the issue. He will be back to install a new thermostat and do a furnace tuneup. Absolutely wonderful young man to work with. Would recommend them to everyone! Thank you!
Always great doing business with Kettle. Luke is friendly, efficient, and knowledgeable.
On time. Courteous respectful and friendly technician and office staff.
On time, friendly, professional.
Diagnostic was quick. Getting a part for repair later this week.
Matthew was friendly and courteous technician. He did a meticulous job checking over the furnace.
Brian did an exceptional job servicing my furnace. He was very knowledgeable, professional, and super thorough. On top of it all, he was very friendly with a great manner. He caught an issue with the intake and exhaust for my furnace that was not correct from installation and he corrected it under warranty. I couldn't have been more impressed with the quality of service from Brian and Kettle Moraine Heating & Air Conditioning!
Great service!
