How to check a HVAC contractor's license in Fullerton

  1. Find the business in the list below, or search all 50 Fullerton listings, and open its profile. You want a Clear status and the C-20 classification (a B license can also cover it as part of a multi-trade job).
  2. Before any money changes hands, verify the license on CSLB's own lookup. Our data comes from CSLB's weekly file, so a very recent change may not show here yet.
  3. Match the license holder's name to the name on the written contract and the person you meet. Ask for proof of workers' comp if anyone besides the owner will work on site. Hiring checklist.
