EPA 608 Exam Overview
EPA Section 608 certification is for technicians who work with regulated refrigerants. The exam is usually divided into Core, Type I, Type II, and Type III sections. A Universal certification generally means passing Core plus all three type sections.
What Each Section Covers
Core focuses on environmental rules, refrigerant safety, recovery, recycling, reclaiming, shipping, and technician responsibilities. Type I covers small appliances. Type II covers high-pressure appliances. Type III covers low-pressure appliances.
Core vs Type I vs Type II vs Type III
Core is the shared foundation. Type I questions usually involve small sealed appliances and recovery during service or disposal. Type II questions focus on high-pressure systems, including recovery levels, leak repair, charging, and service practices. Type III questions focus on low-pressure chillers, purge units, evacuation, and water contamination risks.
How to Use This Practice App
Start with Core, then practice the equipment type you need. Use Quick Drill for short study sessions and Review Missed to repeat the questions that caused trouble. Practice exams are best when you want a test-style score and section breakdown.
Simple Study Plan
- Review Core until the main terms feel familiar.
- Practice one equipment type at a time instead of jumping between all sections.
- Use missed-question review after every drill or practice exam.
- Take Universal practice only after reviewing Core, Type I, Type II, and Type III.
- Use current official or instructor-provided materials for final exam preparation.
Common Weak Areas
Many learners struggle with recovery versus recycling versus reclaiming, evacuation levels, leak repair timing, cylinder handling, and pressure differences between high-pressure and low-pressure appliances. When a question feels tricky, slow down and identify the appliance type first.
