Hiring an HVAC Contractor in San Francisco, California
In California, HVAC contractors typically hold a C-20 license—Warm-Air Heating, Ventilating and Air-Conditioning Contractor—issued by the Contractors State License Board (CSLB). Before you hire, verify the contractor's license number and status on the CSLB website. You can search by license number (up to 8 digits, no letters) or by the business name.
Building permits for HVAC work vary by location. San Francisco has its own building department with specific code requirements. Ask your contractor whether your project needs a permit and whether they will obtain it. The CSLB recommends checking with your local building official beforehand.
When you call, confirm the contractor's license is current and in good standing. Ask whether they carry insurance, what their service hours are, and whether they offer maintenance plans or emergency availability. Get a detailed written estimate and contract before work begins.
