JJ - Jacob Johnson was wonderful! He was professional and empathetic to our situation. Did everything he could to get us with heat! We have used KM Heating for a while now and techs like JJ are why we return each year.

Great job thanks a lot beat the shit out of Mr Hollands dog and pony show
Nice to work with pro’s
Tell your boss you should have a raise🤣

As you can see in my other review Mr Hollands couldn’t get the job done so when I called Kettle Moraine they sent out Dustin Shaw and he got on it right away
With his help after 4 controller boards as directed by Generac he said this enough and we finally got Generac to get us a new generator
It is nice to see a contractor live up to the phrase “ Customer Service” instead of just “ Lip Srevice”
Dusting thank you for all your help your da MAN !

The technician was knowledgeable and friendly and explained everything that was done. And being that he was a former Navy guy we got to share some stories.

Tech came on time and was very knowledgeable and answered all questions I had and end up purchasing a new AC unit, they where able to do same day and finance process was easy, quick and great terms.

Patrick was very professional, friendly and through when he came to do my furnace checkup on my furnace that was installed last Nov by KMH&Cooling. He answered any questions that I had. The work was completed in about 1 hr.

Pete and his assistant were both very polite and professional. They laid out the duct work/electric knowing what it should look before the job was finished. All wiring was properly routed and secured to mother board inside furnace. Pete properly tested humidifier and verified that everything was working. The area was cleaned up after the job was completed. A very professional install of the humidifier.

Answered all the questions I had and gave me helpful info on what the furnace parts were and what to look for. Great job.

Doug was a joy to work with during the fall HVAC tune-up. He explained what he was doing, answered my questions, offered suggestions for regular upkeep and diligently problem solved to get everything working optimally. Thanks!

Update: Spring 2023
The HVAC system was running well all year! Doug came back and performed annual maintenance, cleaning and checking the system. Easy to schedule and work with Kettle Moraine.

Update Update: Spring 2024
Consistent maintenance pays off as small problems are caught and fixed in May before they become a HVAC crisis in July or January. Service personnel are consistently professional. Thank you Kettle Moraine!

Update Summer 2025
Jeremy was super efficient in tuning up the AC units at our duplex. Scheduling service for AC, furnace and hot water tanks was a breeze. Thank you!

September 2025
Dan and crew installed new AC units. They were on time and efficient as they removed the old ACs, explained how they were recycled, and then got the new units in place. They answered questions along the way and gave tips on how to keep the AC running efficiently. I especially appreciate the clear instructions troubleshooting shooting tips that they posted on the blower units.

Couldn’t be happier with the service! Call shortly before 8am about my furnace being completely out and they had Matt to my house by 9am. Matt explained everything very well and with zero pressure. Was able to have a decision made within the hour and to my surprise they were able to have a crew here by 11am! Derek and the crew were very professional and did an amazing job. Thank you for getting our heat back on so quickly for a reasonable price!

Excellent communication!

Always enjoy having Matt to do the work on my furnace! Even brought me my filter

The technician arrived on time, with advance notice he was on the way, including his photo. He explained proper functions of our hvac and humidification systems in plain language and made sure I understood what to do with filters, etc. and when. In total, Paul was everything you could want in a first checkup from a new company, and is a great ambassador for Kettle Moraine, inspiring confidence in their services and maintenance contract pricing.

We cannot say enough positive things about our experience with Kettle Moraine. The whole crew was professional and very expedient but also thorough. We will happily recommend Kettle Moraine to our friends. Thank you so much for replacing our rickety system. It is a big concern that we can cross off of the list.

Very knowledgeable, thorough, professional, and personable.

Jim did an excellent job. Arrived ahead of schedule. Explained everything thoroughly and gave me my service options as well as got us on schedule for AC tune up.

Always professional. Great service. New water heater is great! (Old one made it 36 plus yrs) BENJAMIN is super to.work with
Very happy with Kettle Morraine

Brandon did great work on maintaining my archaic boiler system

Luke did a great job. He is very knowledgeable and treated us like family. He is a true asset to KMH and you are lucky to have him as your employee.

Craig and his team did a great job. Very efficient, explained how the new units operate, and left the place as they found it. I would use them again.
