Jay worked through a holiday weekend to ensure we had all the options needed to make a big financial decision. Thanks!
Couldn’t be happier with the Kettle Morraine service experience. It was nice they texted me a pic of Aaron when he was on the way. Aaron was professional, efficient and patient with our questions. I’ll definitely keep them in consideration for future work.
Excellent service!
Tyler was very knowledgable. Was very polite and answered all our questions.
I'd like to thank Kettle Moraine Plumbing Services for an excellent experience with our recent Remodel project. From estimating to rough- in to trim-out they were true professionals. Nick Guenther is a truly skilled plumber and it shows in his work. I'd like to thank Ben as well for his ability to be flexible and schedule within our deadlines. We look forward to working with you on our future projects.Pat GuinnGuinn Construction LLC

We found Kettle Moraine through a special offer through Costco. After comparing the Costco, Kettle Moraine Heating & Air Conditioning stood out as the best choice for our home. The estimate was accurate and they've stood by the quoted price. The office staff was great about scheduling the work. Matthew lead his crew on the installation, which was timely, efficient & professional. I was given an orientation to the new HVAC system and thermostat. All questions were answered clearly. Warranty paperwork and the inspection were explained in detail. The crew cleaned up after their work was complete. Job well done Kettle Moraine Heating & Air!
