In California, HVAC contractors must hold a state license. The relevant classification is C-20, Warm-Air Heating, Ventilating and Air-Conditioning Contractor. Before hiring, verify the contractor's license status through the California Contractors State License Board (CSLB) online system to confirm their standing and review any complaint history.

Building permits are required for most HVAC work in California. According to the California Building Standards Code, construction, installation, alteration, and repair of buildings and structures require permits. Requirements vary by city and county, so check with your local San Francisco building department to determine what permits your project needs.

When hiring an HVAC contractor, ask whether they hold the appropriate C-20 license, verify their license online, confirm their insurance, and discuss whether permits are needed for your specific work. Review any contract carefully before signing, including warranty and payment terms.
