About the One Hour Air Conditioning & Heating® of Mount Airy Team

Serving Mount Airy & Surrounding Areas Since 1949

One Hour Air Conditioning & Heating® of Mount Airy is proud of its long history serving the Mount Airy community. Our business began in 1949 as a furnace and air duct company. In the 1950s, we began building custom homes and commercial buildings. However, we devoted our attention to HVAC work full-time in 1993.

Every member of our team gets trained according to the highest industry standards. When we arrive at your home, we’ll provide the reliable and neighborly service you deserve. We’ll treat your house like it’s ours, keep it clean, and install or repair and HVAC system suited to your comfort needs.
