Hiring an HVAC Contractor in San Francisco, California
In California, HVAC work falls under the Warm-Air Heating, Ventilating and Air-Conditioning Contractor classification (C-20). Before hiring any contractor, verify that they hold a current state license. You can check a contractor's license status through the California Contractors State License Board (CSLB) online at cslb.ca.gov. Search by license number, business name, or the contractor's name to confirm their license is active and review any complaint disclosures.
