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.

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.

Highly recommend KM Heating & Cooling. Just had a tune up done on our AC unit and Matt Wolf was great to work with. He walked me through everything he did and did a once over so we are set for the future. Thank you KM Heating & Cooling!

Greg was outstanding and was patient as he explained the mechanics of what he was doing and was very conscious as to what I required and kept it within my budget. I highly recommend this company.

Your team was professional and on time. They were friendly and did an excellent job. They also alerted me to another concern which was discovered as they were were working which o greatly appreciated. I would recommend you all to anyone. What a refreshing and good experience with your company and associates. Most Sincerely Happy Home in Sussex

Kyle arrived promptly at noon, the earliestscheduled time for our a/c tune-ups. He introduced himself and immediately went to work. We found Kyle to be both completely professional and congenial while performing his duties ... deliberate and focused He's a very impressive young man! We are happy to request him to return to our residence for the equipment maintenance on our heating units as well.

This is the first time Brian serviced my system. I found him to be the consummate professional. He didn't mind me watching him work, and answered all of my questions. He is meticulous. I am sure he treats my HVAC system as though it were his own.I hope he will be servicing my system next time.

The technician was prompt, professional, friendly and thorough

From the initial phone call to the installation and removal of our old water heater, everyone was absolutely great. They were fast, reasonably priced, and all incredibly polite. Would highly recommend to anyone!

Dylan was an excellent tech. He notified me before his visit, wore booties in the house & was professional & knowledgeable. Many thanks to Dylan for pursuing this trade.

Brett is the best hvac tech in the world. And a nice guy

Had Tyler come out to do maintenance on my air conditioner. He did a great job and was very clean, professional and courteous. I asked him to wear shoe covers in my house and it was no problem.
