Illinois HVAC Notes
Illinois does not have a single statewide HVAC license — licensing requirements are set by municipalities and counties. Chicago is the most stringent jurisdiction: the City of Chicago requires a City of Chicago Refrigeration License (administered by the Chicago Department of Business Affairs and Consumer Protection) in addition to EPA 608 Universal certification. The Chicago HVAC exam covers mechanical systems, refrigerant handling, and local code compliance. Outside Chicago, many Illinois municipalities use the PSI Exams platform administered by the local jurisdiction. Key requirements across most Illinois jurisdictions: EPA 608 Universal certification (required federally for refrigerant handling), 4–5 years of documented field experience, passing a written trade exam, and proof of liability insurance and bond. Contact your city or county building department for the exact requirements in your jurisdiction. The Illinois Department of Public Health oversees boiler and pressure vessel inspections separately.
About the EPA 608 Exam
The EPA 608 Universal exam has 100 questions across 4 sections (Core, Type I, II, III). You must score 70% on each section independently. The Core covers environmental regulations, leak rates, and safe refrigerant handling. Types I–III cover equipment- specific recovery and service procedures. The exam is closed-book.
