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 entirely single-family homes, so commercial HVAC work here is modest, centered on smaller buildings and facilities such as Oakhurst Country Club. Commercial installs in Clayton are permitted through the Contra Costa County Building Division, by contract: the County does all plan checks, issues permits and inspects. Applications are submitted to the City of Clayton, and we handle the application and inspections.

Questions before you call
Do you handle permits for commercial HVAC work in Clayton?
Yes. Commercial installations need permits from the Contra Costa County Building Division, by contract: the County does all plan checks, issues permits and inspects. Applications are submitted to the City of Clayton, and we handle the application and inspections.
Can you replace a rooftop unit without a long shutdown?
In most cases the swap is planned so the space is without cooling for as short a time as possible. We'll walk you through the schedule before we start.
Do you install HVAC for new commercial construction?
Yes. We install complete systems for new buildings, build-outs and tenant improvements, from ductwork layout to final inspection.
