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.
