Bayfield and Ashland County HVAC sales & service


Kevin Zimmerman has always been a big part of the local community. For years, his dry cleaning business served customers in Milwaukee and surrounding suburbs. While working there, Kevin learned about boilers and their inner workings. After realizing there was a need for an affordable and reliable HVAC company in Milwaukee, he decided to take his small interest in boilers and turn it into a passion. Kevin began to take classes to learn a little more about heating and cooling and soon, he began his own heating and cooling business: Comfort Star Heating & Cooling.

Since 2007, Kevin has managed a small crew of dedicated technicians who provide heating, cooling and ventilation services for residents. While we work with several different brands, Comfort Star Heating & Cooling focuses on the Amana products. Amana offers one of the best warranties on their products in the industry and you should have the best in your home.
