Frequently asked questions
Does Illinois require a state HVAC license?
No. Illinois has no statewide HVAC contractor or technician license. IDFPR's full list of the professions and industries it regulates does not include HVAC — the state licenses roofing contractors and (through the Department of Public Health) plumbers, but not HVAC.
Who regulates HVAC work in Illinois, then?
Individual cities and counties. For example, Chicago's Department of Buildings runs its own refrigeration/HVAC licensing program with its own exam, fees, and renewal rules. Requirements vary widely by municipality, and many smaller jurisdictions have no local licensing at all.
Do I still need any certification to work on HVAC systems in Illinois?
Anyone who handles refrigerants must hold federal EPA Section 608 certification, which applies nationwide regardless of state licensing. Beyond that, check with the specific city or county where you'll be working for any local licensing requirement.
Is there a state licensing board I can contact about HVAC in Illinois?
No — since IDFPR does not regulate HVAC, there is no state board to apply to or verify a license through for this trade. Contact the building/licensing department of the municipality where the work will be performed instead.
