In California, the license to look for on an HVAC job is the Contractors State License Board's C-20 classification for warm-air heating, ventilating and air-conditioning. Since January 1, 2025, a license is required for any job of $1,000 or more in labor and materials, up from $500. There's a catch that matters for HVAC. Even below $1,000, a license is required if the work needs a permit of any kind or the person hires anyone to help, so ask whether your furnace or air conditioner replacement needs one. The CSLB's free online license check shows whether a contractor is active, bonded and insured for workers' compensation.
