Hiring an HVAC Contractor in San Francisco, California
California requires HVAC contractors to hold a state license. The licensing type you need is C-20, the Warm-Air Heating, Ventilating and Air-Conditioning Contractor classification. Before hiring any contractor, you should verify their license status through the California Contractors State License Board (CSLB) online license check tool. You can search by the contractor's license number or business name to confirm their license is active and to view any complaint disclosures.
Most HVAC work requires a building permit in California. Code requirements vary by city and county, so check with the San Francisco building department to confirm what permits your project needs. Your contractor can help guide you through the permit process, and obtaining the right permits protects your home and ensures the work meets current building standards.
When you contact a contractor like 72 Degrees HVAC Company, ask about their license type and verify it independently through the CSLB. Understand the scope of work, get a written contract, and confirm what permits will be required for your specific project before work begins.
