Is Type II the same as Type 2?

Yes — the EPA uses Roman numerals (I, II, III) but the certifications are commonly written 1, 2, 3 in shop talk.

What appliances need Type II to service?

High-pressure equipment above 45 psia at 104°F: residential split systems, heat pumps, commercial AC, supermarket refrigeration, condensing units.

What are the Type II annualized leak rates?

For appliances with more than 50 lb of refrigerant (ODS rules): comfort cooling 10%/yr, commercial refrigeration 20%/yr, industrial process 30%/yr. Triggered leaks must be repaired within 30 days or follow a retrofit/retirement plan. HFC systems may have different thresholds under newer leak-management rules — confirm the rule set that applies to your equipment.

EPA 608 Type II Practice Questions — High-Pressure Certification

Type II covers high-pressure refrigeration and AC — anything above 45 psia at 104°F. That includes most residential split systems, supermarket racks, heat pumps, and commercial DX equipment. These free practice questions test recovery and evacuation rules, leak-rate thresholds, the leak repair / retrofit / retire decisions, and the appropriate recovery cylinders for high-pressure work.
