About Us

Midwest Heating & Cooling was founded in 1971 by Dave Harmon, Sr., with a mission to provide local families and businesses with dependable, high-quality HVAC installation and repair services. In 2003, the company was passed down to Pat and Dave Jr., continuing its legacy as a second-generation, family-owned business.


Over the years, the company has expanded its services while staying committed to delivering the highest level of customer care. Our goal has always been to ensure complete satisfaction through the dedication and expertise of our experienced team.
