Kettle Moraine Heating & Air Conditioning, LLC

We’re a third-generation, family-owned team that has served Southeastern Wisconsin for more than 35 years. From our Delafield location, we help homeowners enjoy healthier, more comfortable indoor air without unnecessary worry. Our mission is to give every customer peace of mind through personalized care and 5-star service. Because no installation or repair is exactly the same, we draw on decades of real-world experience to identify the right solution for each home—even when the situation is complex.

We provide HVAC, electrical, plumbing, and radon services, including repairs, regular maintenance, and reliable replacements. Our work also includes whole-home comfort systems, backup generators, solar panel installations, and electrical services. Whatever the project involves, we focus on lasting results and stand behind our work with a 100% satisfaction guarantee.

Our technicians are NATE-certified and participate in continuous training to design, install, service, and maintain HVAC systems. We have been recognized as a Lennox Premier Dealer since 2007, a distinction that requires us to consistently meet high standards and exceed customer expectations. We are also a Mitsubishi Diamond Elite Dealer, supported by rigorous Mitsubishi factory training. As a preferred Unico contractor and A+ provider in Southeastern Wisconsin, our factory- and field-trained team has installed a significant number of Unico high-velocity small-duct systems, earning the Unico Veteran Badge. Through every service call and installation, we aim to deliver the knowledgeable, attentive service our customers deserve.
