Reliable Heating, Cooling, Electrical, Plumbing, & Radon Solutions

Kettle moraine were great to work with, specifically Brent did a great job, didn't cut any corners, made sure I was aware of everything going on during the process as we had a bit of a rare issue with our unit. Handled everything promptly, will be my go to place for anything HVAC related.

I liked laid out floor coverings and Nice job cleaning up after! !

My wife has worked for Costco for 13 years. When we received a quote for replacing our HVAC system, I joking asked," Does Costco have discount for HVAC?" That is how we got in touch with Kettle Moraine. We had a little more than 2 weeks to get this done to qualify for federal and state incentives. Jay Zeman made this the easiest decision to make! He worked with us and responded promptly. He saved us money by investigating and applying every possible discount and rebate. Comparison with competitors pointed everything to Kettle Moraine. Another factor was that any time I had called, a pleasant knowledgeable person answered every question and concern I had! Thanks again to Jay and crew. And to know that they are a complete home repair operation insures that they will be hearing from me when needed!

Been in our home almost 35 years. Couple months ago, I saw water on the floor under our washing machine. Decided to replace the washer. Went to the basement to look above where the laundry room water supply lines come up through the floor and saw an electrical junction box under the supply lines. Checking the box, there were mineral deposits on the cover, suggesting water leak in the past. Figuring electricity and water don't mix too well, I called KM Heating & A/C's electrical division to have someone come out to move the junction box, as our sump pump is plugged into a socket on the junction box. Josh was out on April 19 to do the repair. He chose to move the box over a foot away from the water supply line and managed to get the job done quickly and efficiently. Wiring was added and new conduit with connectors were put in. Couldn't be happier to know the new junction box won't get wet, spark up, or cause a fire. New box and conduit can be seen in the picture.Update: July 25, 2024 - we have two central air conditioning units that needed to be checked to make sure they were working as they should. I went to our “go-to” crew at Kettle Moraine Heating and Cooling. Brent was assigned to the task. He did a thorough check of both systems and reset a blower motor on one. He arrived on time and worked quickly and efficiently. We are looking forward to his return in October to do a check on our two furnaces. Thanks, Brent and KM Heating and Cooling.

Aaron was friendly and helpful!

Had Patrick come out today for a tune up on our central air unit.Also looked at the furnace as some places do not. ?.Was very detailed.Replaced the capacitor.Will be a repeat customer.Went through Home Depot.Thanks again!

I have an elderly couple that we've been long time friends with, and he doesn't like to spend money to fix anything. After looking at it, I told him his 60+ year old furnace had to go. After having a local company look at it he said they claimed he had holes in his heat exchanger and it had to be shut off. I looked this company up and found customer told exact same thing only to find out after his unit was replaced it did not. Not wanting him to work with possible dishonest company and checking other reviews, I told him to call you guys. His wife loved the time spent explaining process and answering questions on July 12th, you guys came out July 16th, electrician put in separate circuit for furnace they did not have, unit installed in 5 hours cleaned up and done. WOW They are so happy, and so am I, grateful how good you were after I mentioned you. And true to form my buddy got a call from you (a lady) and she asked about the heating service, to which he replied ----- How should I know, haven't had to use it yet! HA

Quick and priced fairly. Very happy with our service.

Scott provided me with exactly everything I needed to service my solar power that I purchased elsewhere and subsequently went out of business.

Kevin and Mike did a great job installing our new furnace and air conditioner. They were friendly and worked efficiently. I appreciated that they were very careful while removing the old equipment and bringing in the new. They also did a great job of cleaning up before they left. I''m very impressed with Kevin, Mike, and Kettle Moraine Heating & Air Conditioning.

Great Service

A very friendly tech, Mark Billeb, does a great job of inspecting our furnace, or A/C and thermostat. He respects our house by always wearing shoe coverings, and explains everything he does. Always asks if I have questions, and provides great answers. Always calls to confirm arrival times. I get texts with a picture ahead of time so I know the right person is let into my home. I would endorse them to everyone. They installed both my furnace and a/c and are the only people I have trusted to maintain them both for over 10 years.

We had our AC go out on one of the hottest days of summer and Kettle sent Brett out to check it out for us. We got a new AC and Furnace (ours was from the 70's!) And they work so much better! Brett is very professional and always does a great job with tuneups.

Awesome experience with Kettle Moraine Plumbing Services. The techs were very friendly and professional and Ben saved my life. Awesome job from Ben and truly appreciate the help he gave me replacing my water heater. Ben deserves a raise or promotion 😁

New ac along with the affordable price makes me glad I chose these guys. I will brag about KM for awhile to my friends and family. They are well worth hiring.
