Some third-party pages assert a state HVAC license under the Illinois Dept. of Public Health; this could not be confirmed on an official page and should be treated as unverified.
Issuing authority: No statewide HVAC contractor license; regulated by local municipalities. The Illinois Department of Financial and Professional Regulation (IDFPR) licenses plumbing and roofing at the state level, but not HVAC.. Official page: https://idfpr.illinois.gov/
