On time, very polite. Very happy with work and explanation of work done when finished.

Kyle did a great job going above and beyond ensuring my furnace was in top shape for winter

Once again review: 11/24.Jim came out and did the regular annual furnace service. Really nice guy who answered all my questions. Later, when I discovered my AC option completely disappeared from my thermostat choices he came back within a half hour (wow!) and troubleshot it down to a rare broken wire. I'm happy with this company even when there are problems. Excellent people with excellent customer service.Latest review. Original review written Fall 2023.~~~~Dustin Shaw came by this week, (6/24) took a look at my AC system and recommended improvements that addressed some concerns I had been having. He's coming back next week to install some new equipment that needed to be ordered.What a great guy. He was a high level expert, super friendly and even took on a brief question unrelated to my AC system. I've been with the Kettle Moraine heating company for 8 years and they cover many other skills now. I am happy with them and their experts in every possible way!Dustin is terrific.~~~~~~Earlier reviews below:My thermostat went out so I called my go-to heating company. Brent Von Hoffman was here in 2 hours and worked about 6 hrs over 2 days. The thermostat was the main problem but I was impressed that he found many components that were having problems inside the furnace, but were under warranty. Very happy to get heat again and a professional job of fixing it.~~~~~~~Update: Brent came back in Spring '24 to complete the thermostat job that had to wait for warm weather and balance the airflow. He's still the greatest. A pro who happily answered all my questions and did a great job. I love this company.

Happy with service and timely visit.
