HVAC licenses in California
HVAC contractors are licensed by the state.
Who licenses: Contractors State License Board (CSLB)
License types: C-20 – Warm-Air Heating, Ventilating and Air-Conditioning, C-38 – Refrigeration Contractor, C-43 – Sheet Metal Contractor.
Companies: California requires a contractor license for contracting work above the minor-work exemption in Business and Professions Code 7048 (see also 7026 and 7028). The CSLB says the C-20 classification is the one authorized to install HVAC systems and heat pumps, although a B – General Building contractor may take a prime contract involving two or more unrelated trades and subcontract the HVAC to a C-20.
Local rules: CSLB guidance says local building departments must verify a contractor's license and workers' compensation coverage before issuing a permit; We could not open the statute text on the legislature's site (robots block), so the licensing threshold wording is from CSLB pages only.
Check a license: www2.cslb.ca.gov
Use CSLB License Check to confirm the license is active with a C-20 classification (not just a general or handyman listing) and that bond and workers' comp are on file.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.
We could not confirm every detail from California’s own sources, so treat this as a starting point and check with the agency.
Sources: cslb.ca.gov, cslb.ca.gov, cslb.ca.gov, web.cslb.ca.gov. Checked October 2026 from official sources. This is not legal advice.
Questions to ask
Ask every company the same questions: license number, insurance, EPA refrigerant certification, a written itemized estimate, a load calculation for new equipment, after-hours rates, who pulls the permit, and the warranty. All eight questions.
Seasonal care
Keeping cool in Riverside
