Family-Owned Since 1989

Our story starts with our owner, Ron, opening A&A Appliance company out of his car in 1989. After about a decade in the business, Ron pivoted and joined the company Air Time 500 and rebranded as Switzerland Air. In 2009, he renamed the business Swiss Air Heating & Cooling, LLC.

Swiss Air Heating & Cooling, LLC has blossomed into the full service HVAC company you know and love over the past few decades. It’s taken lots of trial, error, and persistent evolution to get here.
