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. UPDATE: 10/14/2024: In contrast to “global warming”, our part of Wisconsin is now into “global cooling”. To get ready for colder weather, we had KM Heating and Cooling do a check and tuneup of both furnaces. Patrick was the guy who drew the short straw and came out to check the furnaces. The furnaces are six years old and had no servicing done since they were installed. Good thing Patrick checked them over and explained that both furnaces were not delivering the correct gas pressure and those were adjusted to correct pressure. Igniter sensors needed to be cleaned up or those could have failed and the furnace wouldn’t start. It took Patrick about 45 minutes per furnace and ran $268 with tax. With an early and long winter expected this year, it was good money spent to insure heat when we need it. Thanks much, Patrick, and KM Heating and Cooling. UPDATE: December 16, 2024: We needed to have the wiring checked in a ceiling fan light and the bulb sockets needed to be replaced too. The usual option is to just buy another lamp to wire into the ceiling fan. I looked at thousands and nothing appeared to put enough light directly on the kitchen table like our current one did. The bulb sockets were made of Bakelite plastic that deteriorated over the years due to heat from incandescent bulbs we used to use. I replaced the sockets once and spent most of the day on a ladder to do it. Too old to do that anymore. KM Heating & Cooling electrical division said they could check out the light and possibly salvage it for us. Joseph came over and figured out the problem pretty quickly. He changed out the plastic bulb sockets with ceramic versions and the light has 4 arms on it. Joseph took each arm off, found the wiring showed signs of wear, so he rewired the entire lamp fixture. In about 90 minutes, the job was done and the light was back in service again. Joseph was very efficient and precise in his work. When we need HVAC or electrical service, no one else will be touching our house but Kettle Moraine HVAC/Electrical. Thanks, Joseph !! Update: October 16, 2026: Adding on to prior review. I had a number of electrical tasks needing to be done. I don't have enough space to describe all the work we needed done. Google reviews can only be so long. I can't open up a new review. KM Electrical sent Jake Antczak over to do our work. Turns out we knew Jake, who graduated high school with our son. Jake did all the work we needed fast and efficiently. Replaced wall switches worn out and re-wired hard-wired smoke detectors. NO ONE does electrical work than KM Electrical and Solar. Jake will be back !!!

Out water heater went out just before we were supposed to leave on a vacation. I called around a bit and couldn't get much of a response from anyone. When I called Kettle Moraine Heating & Air Conditioning, they were immediately helpful. I explained the situation and that we were in a rush. They were able to move some things around and get us taken care of quickly. The people who came to install the new water heater and remove and dispose of the old one were very pleasant and professional. They didn't leave a single trace that any work had been done! I absolutely recommend them!

Dan and his coworker replaced my furnace.They were efficient and professional. They respected our home by protecting the floors and cleaning up after the work. They answered all my questions thoroughly. Excellent service and a great company to do business with.
My technician was Miguel. A very nice young man. He did a thorough job of cleaning and checking my furnace. He recommended I get a new igniter which I agreed to. He went and picked up the necessary part, replaced it and made sure my furnace was in good working order. We discussed his love of cooking, I am of Mexican descent and he’s Puerto Rican so I let him know members of my family were also Puerto Ricsn and that I didn’t like Puerto Rican rice. 😂 Although the rest of my family love it. Customer service was always outstanding. I always recommend Kettle Moraine

Very happy thus far with a new HVAC install replacing an entire 23 yr old system with Kettle Moraine. I thoroughly researched a handful of vendors and happy I went with them! The entire experience was positive. A thorough quote, very fair price, low pressure sale. Many options were provided. Scheduling was seemless and the new furnace, AC, zoning, dampers and humidifer looks amazing, completed in a day! Very professional install crew - Regan, Joe and Faith install team were amazing! The install site was left clean and ensured everything was 100% functional. Handoff/sign-off of system was through and all my questions were answered. I would recommend Kettle Moriane!

Luke and Brandon, I think, sorry if the 2nd name is wrong. They were very professional and caring about their job. They also explained everything very well. Besides the hot water heater install, they installed an iron curtain system. I give them 10 stars actually!!
Jim went out of his way to find and pick up the filter I needed. Greatly appreciated!

Very old coal/fuel oil boiler converted to an LP system. Unsafe to proceed with the repair. The knowledgeable help from team Kettle Moraine heating was key to keeping us safe. Safety knows no holiday 😀 Thanks Jon and Mark.
