C20 HVAC Contractor License Lookup

Use this page when you need a California C20 license lookup, a list of licensed hvac contractors, or a quick screen before assigning hvac work to a sub. Each row links to a contractor profile with CSLB status, workers' comp, bond, federal records, and permit checks.

California has 12,687 CSLB C20 license records for hvac contractors. 93% currently hold active licenses and 3.1% have at least one federal compliance record. SiteVetter checks CSLB status, SAM.gov debarment, DOL wage violations, OSHA safety citations, EPA environmental records, and building permits in seconds.

What to Check for C20 HVAC Contractors

  • Verify NATE certification for technicians working on your system
  • Ask about experience with your specific HVAC brand or system type
  • Confirm they can provide energy efficiency calculations for new installations
  • Check federal databases: SAM.gov, OSHA, DOL, and EPA records
  • Confirm bond: California requires $25,000+ contractor bond (SB 607)

Why Federal Records Matter for HVAC Work

For hvac work, 3.1% of licensed contractors have federal records that a standard CSLB license check would not reveal. SiteVetter's 6-source lookup gives GCs a faster way to compare subs before bid award, onboarding, or renewal review.

Data sourced from California Contractors State License Board and federal databases. Updated weekly. For official verification, check directly with CSLB.
