Hiring an HVAC Contractor in San Francisco, California
In California, HVAC contractors must hold a C-20 classification license from the Contractors State License Board (CSLB). This license is required for warm-air heating, ventilating, and air-conditioning work. Before hiring a contractor for your project, verify that they hold a valid license and check the status of their license through the CSLB website.
You can look up a contractor's license by visiting the CSLB online license check tool. You can search by the contractor's license number (8 digits or fewer), business name, or the name of the license holder. The CSLB recommends that you verify the license status before signing any contract, as the lookup also includes complaint disclosure information.
Whether you need a building permit for your HVAC project depends on local requirements. California Building Standards Code generally requires a permit for heating and cooling work, but code requirements vary by city and county. Before work begins, contact your local San Francisco building department to confirm what permits are needed for your specific job.
