How to Prepare for the EPA 608 Exam in 2026

The EPA Section 608 Technician Certification is required by federal law for anyone who maintains, services, repairs, or disposes of appliances that contain regulated refrigerants. If you handle refrigerant, you need this card — period.

The good news: with a focused plan you can pass Core plus all three Types (Universal) in a single sitting.

#What the exam actually covers

Every candidate takes Core — ozone depletion basics, the Clean Air Act, recovery techniques, safety and refrigerant handling. Then you choose the Types that match the equipment you'll work on:

Type I — small appliances (≤ 5 lb of refrigerant): window units, vending machines, dehumidifiers.
Type II — high-pressure and very-high-pressure systems: residential split systems, supermarket rack systems, most commercial A/C.
Type III — low-pressure systems: centrifugal chillers.
Universal — pass Core + I + II + III in the same sitting.

Each section is 25 multiple-choice questions and you need at least 18 correct (72%) to pass that section.

## A 3-week study plan that works

Week 1 — Core. Focus on the Clean Air Act (Section 608), the phase-out of CFCs / HCFCs, ozone depletion potential, global warming potential, and Section 609 vs 608. Learn the recovery/recycling/reclaiming definitions cold.

Week 2 — Types I and II. Small appliances first (Type I is the easiest section for most people), then high-pressure systems. Memorize the recovery requirements table by heart — it's the single biggest source of trick questions.

Week 3 — Type III + full-length practice. Low-pressure systems, chiller purge units, and rupture disks. Then take at least two full 100-question Universal practice tests under exam conditions.

#Study materials that actually help

The official EPA Section 608 program page for the current rules text.
A structured study manual (see the box above for our recommendation).
Practice questions — the exam is heavy on specific numbers (pressures, lbs, evacuation levels). You only remember them by drilling.

#Test-day essentials

Bring a government photo ID — no ID, no exam.
Core and Type I are open book at most testing organizations; Type II and III are closed book at every proctored testing site. Confirm with your provider.
Budget about 2 hours for the full Universal sitting.

Pass all four sections in one visit and you walk out with a **Universal card that never expires**. That's the goal.
