Illinois does not license HVAC contractors at the state level — the IDFPR only verifies general business registration. Trade licensing is handled municipally: Chicago requires a Mechanical Contractor license through the Department of Buildings, and most suburbs require local registration plus a plumbing/mechanical license for gas and ductwork. Always confirm an active local license, general liability insurance, and any bond required by the municipality.
