Before hiring an HVAC contractor in California, check whether your project requires a building permit. According to the California Building Standards Code, most work on structures—including heating and air conditioning installations—requires a separate permit from your local building official before work begins. Code requirements vary by city and county, so contact your local building department in San Francisco to confirm what permits are needed for your specific job.

California requires HVAC contractors to be licensed. The state classifies HVAC contractors under two license types: C-20 (Warm-Air Heating, Ventilating and Air-Conditioning Contractor) and C-43 (Sheet Metal Contractor). You can verify a contractor's license status and check complaint disclosure through the California Contractors State License Board (CSLB) online license lookup tool at cslb.ca.gov before signing a contract.

When you hire a contractor, ask them to confirm they hold the appropriate state license for your project type. Always check their license number and current status with the CSLB, review your contract carefully, and understand what work requires a permit in your area before the job begins.
