AIR Heating & Refrigeration started over 30 years ago. "AIR" has always been a family-owned, debt-free business. We desire to do quality work serving the greater Rochester Hills area. My three oldest sons and I (Gary), have been licensed mechanical contractors for many years. I have taught heating and air conditioning in trade school along with teaching high school sciences. My dear wife assists in answering the phone. We are thankful to God for our family and the privilege to serve others.
