Questions before you call
Do you handle permits for commercial HVAC work in Knightsen?
Yes. Commercial installations need permits from the Contra Costa County Dept. of Conservation & Development, Building Inspection, 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.
