Always professional and friendly
I would not go anywhere else

Jacob came to check some issues we were having with some outlets and light switches. Found the problems and fixed everything quickly. Very pleasant professional technician. Definitely will continue using Kettle Moraine Electric!

5 star experience. Fast, Clean, careful & informative. Highly recommend for any HVAC needs!

Brent from KM Heating&Cooling was excellent. Professional, comprehensive and knowledgeable. This company must vet their people well because he was an A-player. We’ve requested him for service on A/C when weather warms up. Exceeded our expectations

Brent was a outstanding service technician, very polite, courteous and explained how to use the new thermostat very well.

Thank You Very Much Brent Nice Meeting You ! Correction it was a new thermostat

Jacob Blubdon was on time, very personable & when thru questions I had.

Brian, came out on a emergency call on a Sunday and explained everything that was going on with our furnace, fixed it right away, and sent us some appraisals on a new unit, to replace our 20 year old furnace and central air.

JJ was great. Would high recommend!.

Efficient and professional work was done … friendly and knowledgeable technicians

Jess was a consummate professional. He had great advice, knew exactly how to diagnose and fix our issues, and was very knowledgeable. Kettle Moraine services are easy to navigate and communication was clear and frequent.

Jacob was great on our install. Communicative and did a clean job. Would recommend.

Always very professional and helpful.

Lucas did a great job fixing our old leaky toilets! Very friendly and did a nice job communicating the problem and solution. We’ve also recently worked with Kettle Morraine for a water heater replacement and had a good experience with that too. Definitely pleased with the company and their team.

Matt was incredibly thorough and did an amazing job! He showed us photos of exactly what he did and explained the process in great detail.

Excellent and prompt service

Greg was very professional & informative. He performed our annual furnace maintenance & installed a new smart thermostat for us. Upon completion, he answered all of our questions thoroughly.

Thorough, efficient, professional, timely and polite. KM has great technicians with excellent customer service skills.

The customer service was great and the technician (Brian) that worked on my furnace was awesome! I definitely recommend them and will continue doing business with them.

The service tech kept me informed of what he was doing and closed his service call after speaking to me. Very nice tech who was easy to talk to.

Very good work and great guys

Matthew was on time, efficient and knowledgeable of the unit and best setting for the house.
Did a good job cleaning the unit and the area when he was done.

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

Good and friendly service

Everyone i spoke with at Kettle Moraine was very professional and informative. I was provided many options and we discussed pros and cons of all to come up with a system that fits my needs the best.
Installation crew was great. They too were very informative as ti what they were doing.
I highly recommend Kettle Moraine for HVAC installations.

Lucas Bizub did a great job and was very informative. He took time to explain everything and I really appreciate that.

Excellent technician!! And what a high quality job he did

Brett arrived as requested. Described the work that was scheduled, performed those task, explained all that was done, and the status of the equipment.
We then went through the invoice and its line items. The credit card was scanned and process completed.
Very personable and worked quietly. Would recommend his technical skills to neighbors and Kettle Moraine if asked.

Very nice and professional. New Furnace looks and functions great.Took less time than was expecting. Thank you.

Great service
Great people

They did our new furnace install in 2022 and that was a great experience! Brent came out to replace our 25 year plus thermostat and was punctual, personable, and professional. I will recommend km heating to anyone who asks.

Kettle Moraine removed and installed a new AC unit at my home. The crew was professional, polite and they did a great job removing, installating and setting up the new unit.

Service tech Brett zielski arrived and removed front cover to my furnace but did not perform any trouble shooting or diagnostics to determine the problem. He asked me what the symptoms were and I told him it sounded like the fan was not coming on and I believed there was a problem with the blower/fan assembly.Brett again did not perform any diagnostics to confirm what I conveyed to him and told me the furnace was to old and should be replaced. I found out from another company that universal blower/fan assemblys are made and could have been installed to complete a repair. Brett never offered that repair option to me. I had the furnace replaced at the cost of 6,000.00 dollars and I believe that the 150.00 dollar cost of the poorly performed service call by Brett should have been applied to the cost of the replacement furnace. That option was never offered by Brett or the kettle moraine heating and A/C company. The new furnace was installed on 1/23 by install technician Mike Radliff and his coworker Joe. Extremely knowledgeable and friendly install team. They arrived at 8 am and completed install by 12 noon. Heat was restored to my very, very cold house by the Lennox merit 96% AFUE efficiency furnace with a sealed burner box for extremely quiet operation. A electrician named Ian had to add a switch and remove an outlet which was all completed the in the same day as well. Ian was friendly and efficient. Kettle moraine heating and A/C partners with a company called permit Flow they submitted permit applications, coordinated with my village on approvals, arranged and scheduled the inspection and closed out permits once everything was complete. Found this process extremely beneficial for busy consumers like my self.

First time we had Kettle Moraine Heating come and do a furnace tune up. Jacob did a fabulous job on my tune up. Very professional and friendly. Will definitely be using them again.

Great service and advice.

Had a PM done on our 2 year old furnace. The technician Matt was very knowledgeable and explained all the work he was going to complete prior to starting the job. He was very thorough and professional. Also he saved me some money on including a future PM on our A/C unit.
A job well done.

Nice job by install crew. Done on time and left work area clean. Install was first class.
