When working with refrigerant recovery equipment, what is the minimum required recovery efficiency for stationary refrigeration and air conditioning equipment?
Correct: (c) 90% of the refrigerant charge. EPA rules require at least 90% recovery efficiency for stationary equipment before disposal or major repair.
A technician suspects acid and moisture contamination in a recovered refrigerant stream. Which precaution best protects recovery equipment during evacuation?
Correct: (c) Install an in-line filter drier ahead of the recovery machine inlet. Filter driers trap contaminants before they reach the recovery unit.
What is the maximum allowable leak rate for commercial refrigeration equipment containing 50 or more pounds of refrigerant before repair is required?
Correct: (c) 20% annually. Commercial refrigeration has a 20% annual leak threshold — stricter than some industrial categories but different from comfort cooling rules.

Exam facts
EPA Section 608 Technician Certification
EPA Section 608 certification is required under the Clean Air Act for HVAC technicians who maintain, service, repair, or dispose of equipment that could release refrigerants. This page summarizes the Core and Type I–III exam structure; UniPrep2Go products are independent prep (not U.S. EPA exam material).
- Questions
- 100 multiple-choice for Universal (25 Core + 25 Type I + 25 Type II + 25 Type III)
- Time
- Varies by certifying organization; many providers allow ~30 minutes per 25-question section
- Passing score
- Minimum 18 of 25 correct (72%) in each section taken; Core must pass for any certification
- Scoring
- Percent correct per section (independent section scores)
- Delivery
- Closed-book proctored exam at approved testing organizations (in-person or online proctored — verify with your certifier)
- Administered by
- U.S. Environmental Protection Agency (via EPA-approved certifying organizations)
Knowledge domains and weights
| Domain | Weight |
|---|---|
| Core | 25 questions — ozone depletion, Clean Air Act, Montreal Protocol, recovery, safety, shipping |
| Type I (Small Appliances) | 25 questions — appliances with ≤5 lb refrigerant (typically sealed systems) |
| Type II (High-Pressure) | 25 questions — residential/commercial AC, heat pumps, high-pressure equipment |
| Type III (Low-Pressure) | 25 questions — low-pressure centrifugal chillers and similar systems |
What changed in the current exam cycle
- AIM Act (2020) and subsequent EPA rules phase down HFC production and consumption — verify current substitute refrigerant and leak-repair requirements at epa.gov.
- New flammable (A2L) refrigerants require additional safety training and handling rules beyond legacy CFC/HCFC/HFC content — confirm current EPA guidance before exam day.
- Section 608 certification does not expire, but technicians must follow current regulations regardless of original test date.
High-yield facts (commonly tested)
- Venting refrigerant to the atmosphere is illegal — recovery is required before opening or disposing of systems.
- Core section must pass before any Type certification counts; Universal requires passing Core plus Types I, II, and III.
- Each section is graded independently: 18 correct out of 25 (72%) is the common passing threshold per section.
- Type I covers small appliances; Type II covers high-pressure systems; Type III covers low-pressure chillers.
- Recovery cylinders must be DOT-approved, labeled by refrigerant type, and not overfilled past 80% capacity by weight.
- Leak repair thresholds and timelines differ by system charge size — high-pressure commercial rules are heavily tested on Type II.
