Central Heating team

Central Heating & Air Conditioning is owned by Lenny and Gina Earnst, They started Central Heating in 2011 after purchasing Central Sheet Metal from John Winchell. Lenny had worked for the Winchell’s since 1997. When it came time for John to retire, he didn’t want to see the shop close after 66 years and knew Lenny would continue to provide the same level of service the community has come to expect.

The Earnst’s purchased the company and changed the name to better reflect their scope of work. Today they continue the tradition of what John’s dad Ralph Winchell started in 1945, a company that provides high-quality HVAC equipment installed by skilled craftsmen.
