## What is the EPA 608 exam?

EPA Section 608 certification is the U.S. Clean Air Act credential required for technicians who maintain, service, repair, or dispose of equipment that could release ozone-depleting refrigerants or many substitute refrigerants. The pathway includes a Core exam plus Type I (small appliances), Type II (high-pressure), and/or Type III (low-pressure) sections; Universal status requires Core plus all three types. Approved proctors deliver the official exam — UniPrep2Go is independent practice only. Always confirm current pass rules and refrigerant updates with EPA and your testing organization.

- Administered by: U.S. Environmental Protection Agency (Section 608) via EPA-approved certifying organizations
- Official format: Closed-book multiple-choice sections (Core and Types I–III); the common prep target is at least 18 of 25 correct (72%) per section on the official exam — confirm live rules with your proctor.

## EPA Section 608 Technician Certification knowledge domains and weights

| # | Knowledge domain | Weight |
| --- | --- | ---: |
| 1 | Core | 25 questions — ozone depletion, Clean Air Act, Montreal Protocol, recovery, safety, shipping |
| 2 | Type I (Small Appliances) | 25 questions — appliances with ≤5 lb refrigerant (typically sealed systems) |
| 3 | Type II (High-Pressure) | 25 questions — residential/commercial AC, heat pumps, high-pressure equipment |
| 4 | 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 EPA Section 608 Technician Certification 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.
