The C-20 HVAC classification is one of the California classifications that requires an active Workers' Compensation policy regardless of how many employees you have.
Under California rules, the C-20 HVAC classification requires an active Workers' Compensation policy regardless of employee count. Even as an owner-only contractor, you cannot claim an exemption with this classification. If you hold a C-20 license, coverage is mandatory now to keep your license active.
Owner-only HVAC techs, small HVAC shops, and C-20 license holders who need compliant coverage to keep their license active.
Many hvac contractors carry Workers' Compensation simply because general contractors, property managers, developers, HOAs, and government projects require a certificate before allowing them on a jobsite. Without one, you can lose project opportunities, get removed from approved vendor lists, and miss higher-paying commercial work.
