EPA 608 Type II Jobs in Illinois

EPA 608 Type II certification covers high-pressure refrigerant systems — the equipment category that dominates residential and light commercial HVAC work, including split-system air conditioners, packaged units, heat pumps, and most commercial rooftop equipment. In Illinois, Type II is frequently required for installation and service technicians working in the residential market, and is the most common type-specific certification listed by contractors who haven't yet mandated Universal.

In Illinois, the split between employers requiring Type II specifically versus Universal has been shifting toward Universal — partly because R-410A is being phased down under AIM Act regulations and newer refrigerants (R-32, R-454B) don't change the certification category structure. Technicians with Type II who are planning for the long term are well-served to complete Universal sooner rather than later, as the refrigerant landscape continues to evolve and employers want flexibility across equipment types.
