A Family-owned HVAC Company with Midwestern Values

Harker Heating & Cooling has been a leader in HVAC services since the company was first launched in Madison by the Harker family in 1949. Since then, our heating and cooling company has continued to evolve with the changing HVAC landscape to bring Dane County families the comfort they deserve.

History of Harker

In the late 1980s, the Harker family sold the company to Tim Heiar, and today our company is owned by his son Luke, along with partners Oscar Wendt and Marcus Nelson. Over the years, Harker earned a reputation for excellent service and grew its residential and commercial divisions into one of Dane County’s most successful businesses. You might have even seen a few of our humorous commercials on television or heard our famous jingle on the radio!


Madison’s Honest HVAC Company

Together with our team members, HVAC technicians and manufacturer partners, we’ve been able to sustain a company that puts its Midwestern values up front and center. When you’re in need of HVAC repairs or replacement, you can bet on receiving an honest estimate and a firm handshake to demonstrate our commitment to serving you.
