Erik was friendly, knowledgeable and let us know about ways to be proactive moving forward. We moved to the Mukwonago area a couple of years ago and Kettle Moraine has always been great when we've had them service our furnace and AC unit.

Really happy with how quickly someone was able to come out and look at my on demand water system. Both Brad and Cory were knowledgeable and discovered that it wasn't a major fix which saved me money. They were honest and efficient. I'll be calling Kettle Morraine if I need help in the future

Daymon from Kettle Moraine HVAC did a fantastic job servicing our A/C unit. He was personable and professional. He was right on time and finished right on time. He made the effort to explain what he had done and supported it with pictures. Because of his attention to detail, I am certain our unit will operate much more efficiently. Way to go, Daymon!

Miguel, my service technican came to check out my furnace for the up coming Winter season. I always have a check up each year because I consider that to be a very important thing to do. Miguel was on time and proceeded to give my furnace a through going over. He was very efficient. I would highly recommend him to be your technician too.

Brandon did a fantastic job making sure my HVAC system and whole-home humidifier are running as they should.
We had been told by another HVAC company that we needed to augment our current system or its life expectancy would be significantly reduced. Jacob did a thorough inspection and explained In detail why that was unnecessary, Saving us over $2500! Thanks Jacob!

Everything was top tier from beginning to end. The young lady on the phone really made me feel comfortable. I believe her name was Brianna. Brad was on time and very efficient. He wasn't even bothered by my little dog. He made sure I understood everything. He also let me know how important it is to have a yearly checkup on my new hot water heater. Thank you Brad.
