How to Verify a HVAC Contractor (C20) in California

California requires all contractors performing hvac work valued at $500+ to hold a valid CSLB C20 license. Of the 12,316 licensed hvac contractors in the state, 95% currently hold active licenses and 3.2% have at least one federal compliance record.

Manual vetting takes 45+ minutes per contractor and routinely misses violations in databases most people don't know to check. SiteVetter runs CSLB status, SAM.gov debarment, DOL wage violations, OSHA safety citations, and EPA environmental records in seconds—creating a timestamped compliance artifact.

Verification Checklist for 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 Verification Matters for HVAC Work

Under California's "Controlling Employer" doctrine, general contractors face liability for subcontractor safety violations. For hvac work specifically, 3.2% of licensed contractors have federal records that a standard CSLB license check wouldn't reveal. SiteVetter's 5-database check catches what a single-source verification misses.
