A Passion for People—Home and Business Comfort Solutions Since 1989

At Pat’s Heating & Air Conditioning, home and business comfort means much more than providing the best heating and cooling solutions to meet your needs. Comfort means integrity, honesty, passion, and commitment to our customers. We know you are welcoming us into your home and we don’t take that for granted.

As a family owned business, we are part of the Greater Lake Country community. Our customers are our friends and neighbors, and that’s the way we treat you. You’ll see Pat’s Heating everywhere—in our service trucks in the neighborhood, sponsoring community events, and serving our area businesses. We invite you to ask anyone you meet about Pat’s Heating. Our customers are our best advertising.

With today’s new and innovative heating and cooling technology options, the choices can be overwhelming. You need a trusted partner who will listen to your needs, guide you through selections, and allow you to make the final decision based on your needs and budget without pressure.

Based on our more than 25 years in the business, we offer several well-respected manufacturers’ products including Carrier and many others—but we service all brands, makes, and models. We offer a 100 percent customer satisfaction guarantee on all of our installations.

Pat’s Heating services the Greater Lake Country area, including Oconomowoc, Chenequa, Delafield, Dousman, Pewaukee, Hartland, Ixonia, Merton, Wales, and Kettle Moraine. We also serve Brookfield, New Berlin, Menomonee Falls, Mukwonago, and many other communities.

Over the years, our customers have come to depend on us for annual maintenance and many ask for their favorite techs by name. That’s service with a personal touch you can trust.

Give us a call or schedule an appointment online—we’ll show our continued commitment to exceeding your expectations.


Refer us to your family and friends—when they purchase new equipment, you’ll receive a certificate for “Dinner On Us” as a token of our appreciation.
