EPA 608 Practice Test: Find Your Weak Section Before Test Day
Free practice tests in the real Section 608 exam format, with the rule behind every answer. Score each section, spot the weak one, drill it before you book.
Practice test by section: Core, Type 1, Type 2, Type 3, Universal
A free EPA 608 practice test is open for each section, 50 questions per section plus a 100 question Universal exam, with no signup. Pick the section that matches the equipment you service. Each section is scored on its own at 18 of 25, so a strong Core will not carry a failed Type. Every EPA approved organization, ESCO Institute and Trade Masters Online included, examines each level the same way.
What's on the EPA 608 Exam
The EPA 608 exam covers four topic groups: refrigerants and their classes, federal regulations, recovery and leak repair, and safety and equipment standards. The practice tests on this site follow the same outline, 300 questions with no signup and all 880 with a free account, with an answer explanation on every question.
Refrigerants & their classes
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. Core tests every refrigerant family, from the CFC and HCFC legacy to the low-GWP A2L refrigerants arriving under the AIM Act.
Federal regulations
What EPA 608 certification requires under 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.
Recovery, recycling & leak repair
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 reverified those thresholds against the current eCFR, the 35% figure on some older sites is the pre-2019 rule.
Safety, equipment & standards
PPE and refrigerant safety, AHRI 700 and 740 equipment standards, micron gauges and manifold sets, and per section coverage for Core, Type 1, Type 2, and Type 3.

Exam-accurate format, instant explanations, weak spot tracking

Every question mirrors the real exam: 25 questions per section, the same 18 of 25 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 rereading what you already know.
