Professional, knowledgeable and thorough. Explained all the details and presented all the available options without pressure sales tactics.
Excellent service for a problem furnace fan motor. Even cleaned out the acorns from the ground squirrels! They gave me options and did not pressure us into a huge sale. I would recommend Kettle Moraine!
Excellent experience... So far, very impressed with both AC and Furnace units. Extremely fast, friendly, and professional service... Learned 3 or 4 employees live locally to us also.Thanks!
Corey from Kettle Moraine Plumbing and Heating came out the same day I called to help us out with a plumbing issue. He was very fast and offered great advice. They are now my go to plumber.
Jacob Johnson is a very knowledgeable and friendly young man. Very willing to answer any questions and was very capable of fixing my problem with the furnace as well as installation of the new thermostat. You are very fortunate to have him as an employee.
Matt was extremely thorough and found and fixed issues that would have caused problems down the road. We are very satisfied with our furnace tuneup. Thanks Matt.
Tyler came out today to diagnose a furnace issue. He was clear and concise with our options for both repair and replacement, patiently explained what those options meant and helped us make an informed decision. KM was at our house once this past year replacing an A/C and there's a reason we went with them again.
Always very professional and helpful.
Very helpful with great results
It was a pleasure working KM Heating. The service was great and the employee was very helpful and wonderful to work with.
Greg did a great job. Very professional, courteous.
Paul came out for my Fall check up. It was a great experience through out his visit. He kept me abreast as to what he was doing and pointed out any concerns he had with my system. It was a no pressure, honest service.
I left a less than favorable review yesterday due to the fact the technician did not wear a mask or ask if he should. I have since received a phone call from the owner (Tim) stating that it is now policy to wear a mask if owner requests. Owner should also mask out of courtesy for the tech. I feel this demonstrated good customer service.
Jeremy was experienced, responsive, and happy to share info while he worked. Awesome customer experience.
Kyle was very knowledgeable & courteous! My furnace is working again!
Jeremy was a fantastic HVAC tech. He worked quickly and efficiently at installing our smart thermostat. Would highly recommend and use this company again.
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.
Called 15 minutes ahead and arrived on time, as expected. Performed Heating Tune Up efficiently and communicated professionally. Self-directed and completed the tune up without issues.Took the time to share his work by showing pictures and explaining digital results.
All of the Kettle Moraine employees are exceptional with regards to being professional, courteous, helpful, knowledgeable and experts in their field ! I am always pleased with their service ! Most recently those of service were Bill B, Mike, Matt, and Jason ! My condo is now safe and warm ! Thank you Kettle Moraine !
We just had a new furnace and a/c installed by Mike and Joey. They did a great professional looking job! The electrician Josh finished the install with his fine work. They were fast, efficient, and cleaned up the area when they were done. Thanks to the salesman Timur and those mentioned for making the process of replacing our system worry free!
On time, polite and makes a person comfortable with their professionalism!!!
Excellent service, expert installation & followup.
Kettle Morrain is an excellent company. Brent, our technician solved the problem. We highly recommend this company.
Gary was thorough and professional. Explained everything very well.
Cory is professional and he is an expert in plumbing, evidenced from his trouble shooting skills when the leaking spot was hided and not obvious. He identified the leaking was from a pipe behind the tile wall in the bathroom, and fixed it in an efficient and timely manner! We are so happy it is not leaking anymore! Thank you so much, Cory! You are awesome!
FANTASTIC.. KNOWLEDGEABLE..ON TIME..POLITE...KYLE IS GREAT !!
Friendly staff great attention to detail and showing me what was done
Shawn was great and explained his service work and overview very well
Very professional and pleasant. Got right to work. Did a fine job. Explained everything.
Always professional. Great service
The workers who installed my new air conditioner, air handler, bathroom fan, and thermostat were very nice and hard workers. They were on time and they cleaned up the area before they left.I would highly recommend using Kettle Moraine Heating and A/C because installations in a condo bldg. takes a different kind of expertise.
Very helpful and made sure to go over everything when done
Patrick did an excellent job and I am now all set for the winter.
Very professional, tech arrived with in allotted window, and was very helpful. While here he discovered that since the install of my furnace in 2019 it has not been functioning at expected efficiency.
Kettle Moraine Heating & Cooling is a top tier company. We replaced our home "builder" furnace and AC unit with the top of the line Lennox system and couldn't be happier. Our home us more comfortable and our energy bills are lower because of the technical design features. I cannot say enough about the install team and Luke our semi annual maintenance technician. Thank you Bill Brink for creating a highly trained staff and running a 1st class H & C Company.
