Illinois HVAC technician license requirements
The answer
Illinois has NO statewide HVAC license — the professions code (225 ILCS) contains no HVAC licensing act. Cities and villages regulate HVAC contractors locally (Chicago and many suburbs register or license mechanical contractors). EPA Section 608 certification is federally required for anyone handling refrigerants.Your paths to the license
EPA 608 + training
Get EPA Section 608 certified and train through a community-college HVAC program, an apprenticeship, or on the job. No Illinois state license exists.
City registration to contract
To contract or pull mechanical permits, check the municipality — Chicago and many suburbs require contractor registration or licensing with their own rules and fees.
Watch the adjacent licenses
Plumbing-connected work (e.g. boiler water lines) can trigger the IDPH plumbing license, and some cities fold HVAC under electrical or plumbing permitting — verify locally.
