How to Verify a Refrigeration Contractor (C38) in California

California requires all contractors performing refrigeration work valued at $500+ to hold a valid CSLB C38 license. Of the 1,734 licensed refrigeration contractors in the state, 95% currently hold active licenses and 4.8% 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.

Why Verification Matters for Refrigeration Work

Under California's "Controlling Employer" doctrine, general contractors face liability for subcontractor safety violations. For refrigeration work specifically, 4.8% 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.
