In California, HVAC contractors must hold a state license. The relevant classification is the C-20 Warm-Air Heating, Ventilating and Air-Conditioning Contractor license, issued by the Contractors State License Board (CSLB). Before hiring any contractor, verify their license through the CSLB online license-check tool at cslb.ca.gov. A valid license number does not contain letters and is no more than 8 digits. You can search by license number, contractor name, or the name of an associated individual.

Most HVAC work in San Francisco requires a building permit. The California Building Standards Code requires a separate permit for construction, alteration, repair, or improvement to any building or structure. Permit requirements and processes vary by city and county, so contact your local San Francisco building department to confirm what permits your project needs before work begins.

When you contact a contractor, ask about their license status and when it was last renewed. Request a written contract that specifies the scope of work, materials, labor costs, and timeline. Understanding permit requirements upfront helps avoid delays and ensures the work meets local building codes.
