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.

Excellent! They are knowledgeable, respectful, timely and just down right friendly. Used them for years. Will keep using them for years!!

It's been a long process (not the fault of Kettle Moraine) from a power surge in May to the install today, but working with this company has been fantastic from start to finish. The estimate was very thorough. Timur took dozens of pictures and measurements, and he took excellent notes. He was at my home for 2 hours, then wrote up 3 estimates (different efficiencies of equipment, bundles, etc) before driving away.Financing was extremely easy also. Working with Sheri on various issues (again, not KM's doing) over the summer was very enjoyable. She's excellent representative for the company.The installation was fantastic. Bill and Scott took care of everything! My husband barely knew they were there. They came in, took out the old units, and installed the new ones. When they were finished they walked hubby through what they'd done and what we need to do in the future for maintenance.To be honest, we decided to call Kettle Moraine for an estimate because of their tv commercials, which are hilarious. However, after comparing their estimate process with those of other HVAC companies, there was no question about who we'd choose. We had other HVAC companies spend less than 20 minutes with me, and said, "maybe the ac unit works, maybe it doesn't, but we won't know until it's powered up". I want going to take that chance.The professionalism and helpfulness of everyone we spoke with or worked with was just incredible. We recommend Kettle Moraine Heating and Cooling most highly.

Professional and courteous. The job was done quickly and the furnace is already working great. Would recommend to anyone.

Avery efficient ; professional; caring person!!!.

Brett did a great job. He's knowledgeable, friendly, and honest.

Responded quickly due to my furnace not working properly and provided a diagnosis along with the part being ordered and treating this issue urgently. Thanks Matthew Fyksen!!

Punctual, Professional. They take the time to show their work and discuss how to fix the problem with options.

Three great guys did a good job on a hot day!

Courteous, knowledgeable and professional!

Pete and Tucker were great! They installed a reliable and super efficient A/C for us. They took care with our floors and cleaned up afterwards. They answered all our questions and walked us through what they did. Highly recommend Kettle Moraine Heating and Air Conditioning.

Good job identifying the age af my furnace and AC

Paul, did a great job with connecting with me to see if him coming earlier than scheduled would be okay. He was very professional and kind. Thank you for your service on our furnace today

Used their Plumbing services today.Cory was efficient and friendly. He kept me informed during the entire process. The tasks were completed quickly, based upon the issues that came up. Great company to work with.

KETTLE MORAINE, installed my new Lenox furnace in 2016. The install crew was very efficient and completed the install in 1 day. They have performed yearly maintenance service ever since. Brian has been our tech for several years now. He is very personable, knowlegable, focused, and does a great job. He has been proactive in replacing parts known to be problematic or on recall. Always cleans up when done. This year 2024 Aron provided outstanding service PM my heating and Ac systems. Early this October my thermostat froze up and would not work. Aron returned solved the problem and showed me how to reboot it again so I could fix it myself. Thanks Aron and thanks to Kettlemorane Heating and air conditioning for the geat service for the last 9 years.
