I have really appreciated the care and attention Kettle Morraine has given us. We e worked with the technician Matthew Wolf and he’s been a wealth of knowledge to help us. He also was so patient as our three young kiddos ran amok and were peppering him with questions.

David Ysseldyke

Luke was fantastic- timely, professional and conscientious.

The team at Kettle Moraine Heating and Air Conditioning did a fantastic job today installing my new furnace, AC, humidifier, dehumidifier, and thermostat! They were very thorough & efficient, walked me through everything I needed to know about my new equipment, and left the area cleaner than it was when they arrived! I’m very happy with their work and would recommend to anyone looking for a local, reputable service company!

Judy Skinner

Kyle was professional. He answered all our questions. We will thank him every time we turn our furnace on.

Jennifer DeSteno

Installed a system a few years ago and have been using them for annual maintenance for many years. The technicians are always excellent - technically skilled, personable and helpful. I'll continue to use KM Heating and recommend them to anyone in need of these services. I also love their text system for appointments - easy to confirm, and also alerts that your tech is on the way - complete with photo so you know whom to expect!

Chris

KM does a great job helping keep up with my regular HVAC maintenance and repair. I've had parts replaced and even a full new AC unit at reasonable prices, with work done quickly and done well.I appreciate their honesty as well. I've got a 20+ year old furnace that's still rocking and rolling and have yet to have a pushy conversation about replacing something that's still running great.

Brian Reagles

We had our older furnace looked over and cleaned and the tech Kyle was friendly and very knowledgeable about furnaces and AC units. I highly recommend working with this company for your furnace or AC needs.

Brian Ries

Great service . Very professional. Showed up early.

Matt Olsen

I bought my furnace a couple years ago through Tradewinds (now Kettle Moraine) and recently had a tune-up/inspection completed by Aaron. He arrived timely, made some tweaks to maximize the furnace's efficiency, and gave me useful tips. Top-notch service!

Kettle Moraine Heating and Cooling sent Dustin out to do a seasonal cleaning and check up on our Geothermal system. Dustin was on time as usual with Kettle Moraine Heating and Cooling, and did a thorough inspection and filter change and reset our thermostats for the coming winter. I would rate this company as top notch in all aspects from my initial call to completion. Kettle Moraine Heating Cooling sets the bar for the highest ranking in customer service, expertise and responsiveness which all other companies should strive for. If you want or need the services they offer you will not be disappointed.

This is our first experience with the heating side of your company. We are learning what hasn’t Been done with the previous company we used for over 15 years.We are impressed with the quality and attention detail.

Scott NYB

1729281929

Had an unusual furnace issue exacerbated by my inadvertent clearing of fault codes which resulted in the probable unnecessary replacement of a costly part. Tim, the service manager credited the previous cost to the new correct repair. This is a stand-up company whose default position is great customer service & consideration which is a rarity these days. I highly recommend them. They have earned my trust & respect. Top shelf organization.

Jacob is an excellent technician! He notified me that he was on his way & arrived 15 minutes earlier than the window I had been given. Completed my furnace tune up & reported all that he had done. He answered all my questions. Very personable & friendly. A+
