Under Section 608, what is the maximum fine per day for intentionally venting a Class II refrigerant?
Four certification types under the federal Clean Air Act. Each test mirrors the real exam: same format, same question count, same 72% passing threshold.
Every practice test and practice exam here mirrors the topics the real ESCO-administered exam tests. Here's what each EPA certification practice test covers — with instant answer explanations on every question.
Identify CFCs, HCFCs, HFCs, and the newer HFOs — plus common refrigerants like R-22, R-410A, R-134a, R-404A, and R-717 (ammonia), their oils, and cylinder color codes. See the full EPA 608 refrigerant types and low-GWP A2L refrigerants.
Section 608 of the Clean Air Act, the Montreal Protocol, ozone depletion (ODP) and global warming potential (GWP), and the 2026 AIM Act HFC phasedown. Know the venting ban, de minimis releases, and civil penalties.
Refrigerant recovery vs. recycling, required evacuation and deep-vacuum levels, recovery-cylinder handling, and the tiered leak-rate thresholds (10% / 20% / 30%) that trigger mandatory repair, retrofit, or retirement. We re-verified those thresholds against the current eCFR — the 35% figure on some older sites is the pre-2019 rule.

The real Section 608 exam costs $10–$40 per attempt. Fail once and you rebook, wait, and pay again. Pro unlocks the full AI Tutor (1,000 questions/month), targeted weak-spot drills, advanced analytics, and every feature we ship — forever.

Beyond practice tests — these tools identify exactly what you don't know and fix it before exam day does. The mix of Free and Pro features below reflects the wrong-answer patterns we see across the question bank.
Most technicians fail the Core section because they memorize answers without understanding why. The AI Tutor explains any Section 608 concept in plain trade language — so the answer sticks under exam pressure.
Same format, same question count, same 72% passing threshold. Plus analytics, explanations, and unlimited retakes.
If you searched for a general EPA practice test for HVAC work, this is that test: Section 608 is the EPA certification for anyone who services, maintains, or disposes of equipment containing refrigerants, and every question in this practice bank is written for that exam.

Three things do the heavy lifting: exam-accurate questions, instant explanations, and weak-spot tracking — free to start.
Every question mirrors the real exam: 25 questions per section, the same 72% passing threshold, and the same topic mix as the official ESCO outlines.
Miss a question and the explanation appears immediately — the fastest way to turn a wrong answer into a point you keep on exam day.
Your weak-spot chart shows which section is costing you points, so you drill what you actually miss instead of re-reading what you already know.
Every tool on this platform is free to use. Choose by section, format, or study style. All 569 verified questions are checked against 40 CFR Part 82 and current AIM Act requirements. We built the bank from official ESCO study materials, and each question passes a 3-layer validation — structure check, fact check against our verified facts table (every fact carries a source citation), and explanation review — before it goes live.
Built to get HVAC technicians through Section 608 on the first attempt. Start free in 3 seconds — upgrade when you're ready.
