    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.

    Sample questions

    1. Type II certification covers refrigeration equipment using high-pressure refrigerants. R-22 was a:

    1. A. CFC
    2. B. HCFC
    3. C. HFC
    4. D. HFO
    Show explanation

    R-22 (chlorodifluoromethane) is an HCFC. Production of virgin R-22 ended January 1, 2020 in the U.S.; only reclaimed or recovered R-22 may be sold for servicing existing equipment.

    Ref: 40 CFR §82.16

    2. For a high-pressure appliance with > 200 lb of refrigerant charge, the required recovery vacuum using post-Nov-1993 equipment is:

    1. A. 0 in Hg
    2. B. 10 in Hg
    3. C. 15 in Hg vacuum
    4. D. 25 in Hg vacuum
    Show explanation

    EPA Table 1 (40 CFR §82.158): high-pressure systems > 200 lb must reach 15 in Hg (≈ 7.5 psia) using post-1993 recovery equipment. Smaller systems require less vacuum.

    Ref: 40 CFR §82.158 Table 1

    3. A common replacement for R-22 in new residential A/C installations is:

    1. A. R-410A or R-32 (or R-454B in newer systems)
    2. B. R-12
    3. C. R-134a only
    4. D. R-123
    Show explanation

    R-410A has been the dominant R-22 replacement since the 2010s, with R-32 and R-454B (A2L, mildly flammable) becoming standard in newer systems as the AIM Act phasedown progresses.

    Frequently asked

    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?

    Commercial refrigeration: 30%/yr triggers required repair. Comfort cooling: 10%/yr. Industrial process: 30%/yr. Triggered repairs must be completed within 30 days.
