My wife has worked for Costco for 13 years. When we received a quote for replacing our HVAC system, I joking asked," Does Costco have discount for HVAC?" That is how we got in touch with Kettle Moraine. We had a little more than 2 weeks to get this done to qualify for federal and state incentives. Jay Zeman made this the easiest decision to make! He worked with us and responded promptly. He saved us money by investigating and applying every possible discount and rebate. Comparison with competitors pointed everything to Kettle Moraine. Another factor was that any time I had called, a pleasant knowledgeable person answered every question and concern I had! Thanks again to Jay and crew. And to know that they are a complete home repair operation insures that they will be hearing from me when needed!

I had Kettle Moraine in for a clean and tune on my old furnace. I recieved a confirmation text along w a pic of my tech and the aproximate time of his arrival. Dylan arrived on time looked like the pic I recieved and did a great job. The cleaning was thorough and took about 1.5 hours as he had to dismantle a number of parts to do a thorough job investigating and cleaning the Internal parts of the furnace. Pictures of critical items were taken and after the cleaning discussed. Would highly recommend.

We are very pleased with the professional workmanship from Sam (the Sales Rep.) to Kevin, Josh, & Mike (the Installation Team), to Scott R & his partner (the Electrician Team) from Kettle Moraine H&AC. After our old furnace finally died on us, they came to our home on the same day and installed a wonderful Lenox Efficiency Furnace the next day. This was an outstanding experience from the moment we made the initial inquiry to replace our furnace. We highly recommend this company for anyone in need of heating & air conditioning replacement or repairs.
