EPA 608 Prep: Practice Tests

About this app

Pass the EPA 608 exam — Core, Type I, Type II and Type III — with a practice test app built for working HVAC technicians and trade students.

WHY THIS APP IS DIFFERENT

- Built for the 2026 rules. The refrigerant world changed on January 1, 2026: the AIM Act leak-repair program now covers HFC appliances down to 15 lb, with 10/20/30% leak-rate triggers, and A2L refrigerants are entering the field. Many EPA 608 study guides still teach pre-2026 numbers. Every question here reflects the current rules, and 2026 changes are marked with a badge so you know exactly what is new.

- Every answer cites its source. No mystery answers. Each explanation names the regulation or standard behind it: 40 CFR Part 82, the Part 84 HFC rules, DOT cylinder requirements, ASHRAE classifications. If we can't source it, we don't ship it.

- One-time purchase, no subscription. Try the app free, then unlock everything forever with a single purchase. No monthly fees, no accounts, no ads.

- 100% offline. Study in the truck, in the shop, in the mechanical room. Nothing to sign into, nothing to sync.

WHAT'S INSIDE

- 400 exam-style EPA 608 practice questions: Core, Type I, Type II, Type III (100 each)
- Study mode — learn topic by topic with instant explanations
- Practice mode — shuffled, scored sessions
- Smart Practice — drills your weak spots 3× harder and retires what you've mastered
- Mock exams in the real format: 25 questions, 70% pass mark, realistic topic spread
- Mistake review — every wrong answer becomes a retry queue
- Readiness ring and per-topic stats so you know when you're ready
- Study streak to keep you moving daily

WHAT THE QUESTIONS COVER

Core: ozone depletion, the Clean Air Act and Montreal Protocol, refrigerant classifications, recovery, recycling and reclamation, the sales restriction, cylinder safety and shipping, and the 2026 leak-repair rules.
Type I: small appliances and their recovery requirements.
Type II: high-pressure appliances, leak detection and repair triggers, evacuation levels.
Type III: low-pressure chillers, recovery and evacuation levels, leak repair.

HOW TO STUDY WITH IT

1. Read every explanation in Study mode, not just the answer.
2. Let Smart Practice keep serving what you got wrong.
3. Pass a mock exam in the real format comfortably, twice.
4. When every module is green on your readiness ring, book the proctored exam.
