A technician wants to use system-dependent (passive) recovery on a Type II appliance. What is the largest charge on which Section 608 allows this method?
Correct: (b) 15 pounds of refrigerant System-dependent recovery equipment, which relies on the appliance's own compressor or pressure, may be used only on appliances holding 15 pounds of refrigerant or less. Larger appliances need self-contained recovery equipment.
Using recovery equipment manufactured after November 15, 1993, what evacuation level must a low-pressure appliance reach before it is opened for a major repair?
Correct: (d) 25 millimeters of mercury absolute Section 608's evacuation table sets low-pressure appliances at 25 mm Hg absolute when the recovery equipment was made on or after November 15, 1993 (25 inches Hg vacuum for older machines). 25 mm absolute is roughly 29 inches of vacuum, so it is the deeper of the two levels.
A service technician must evacuate a residential split system holding 8 pounds of R-410A before opening it for repair, using a recovery machine made in 2019. What recovery requirement applies?
Correct: (d) The system must be evacuated to 10 inches of mercury vacuum R-410A falls in the 'other high-pressure' row. Under 200 pounds, recovery equipment made after November 15, 1993 must pull 10 inches of Hg vacuum before the system is opened. Percentage targets such as 80% or 90% apply only to small appliances.

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 | Official 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.
