Is your EPA 608 practice test still teaching rules that changed?

Most guides on the market predate the AIM Act phasedown and the A2L refrigerants now shipping in new residential systems. This one is written from 40 CFR Part 82, every answer carries the citation it came from, and it is current to 2026.

Why are HFCs like R-410A still regulated even though they have zero ozone depletion potential?

ABecause they contain chlorine
BThey have high global warming potential and are phasing down under the AIM ActCORRECT
CBecause they are flammable
DThey are no longer produced in the US

HFCs have zero ozone depletion potential because they contain no chlorine, but they carry high global warming potential and are phasing down under the AIM Act. This is current 2026 material that older guides miss.

EPA 608 exam, answered

Is the EPA 608 exam hard?
It is not mechanically difficult, it is a recall test. Most people who fail mix up the recovery rules and pressure ranges across Type I, II, and III, or they underestimate Core. Structured practice with cited answers is what moves the pass rate.
What is the passing score?
Appendix D to 40 CFR Part 82 sets 70 percent for the closed book sections and 84 percent for the open book Type I mail in option. The closed book sections are commonly administered as 18 of 25 correct, which is 72 percent.
Are the questions current for 2026?
Yes. The material covers the AIM Act HFC phasedown (85 percent reduction by 2036), the 2025 sector GWP limits, A2L refrigerants such as R-32 and R-454B, and R-22 reclaim only status. Older guides predate most of this.
Is this official?
No. It is an independent, unofficial study aid, not affiliated with or endorsed by the EPA or any certifying organization. It does not include or grant certification. All questions are original and written to the public regulation.
