Serving Clayton
Clayton is about 17 miles southwest via SR-4 and Kirker Pass Road from our Antioch shop, and we serve all of it, including Dana Hills, Clayton Wood, Oakhurst and Cardinet Glen. Clayton is almost all owner-occupied single-family homes at the foot of Mount Diablo, where hot valley summers and frosty winter mornings keep both the AC and the furnace busy.

Questions before you call
Do you serve all of Clayton?
Yes. We serve all of Clayton, including Dana Hills, Clayton Wood, Oakhurst and Cardinet Glen. Call with your address and we'll confirm the first available appointment.
Do you work on both homes and businesses in Clayton?
Yes. Along with residential AC and heating, we repair, replace and maintain commercial systems such as rooftop package units and split systems for offices, shops, restaurants and apartment buildings.
What should I have ready when I call?
Your address, the type of system (central AC, gas furnace, heat pump or package unit), roughly how old it is, and what it's doing - noises, smells, error codes or no air at all. That helps us bring the right parts.
