Introduction
This structured EPA 608 Type 2 Certification Exam for 2026-2027 provides 25 high-quality
exam-style questions with correct answers and rationales. It emphasizes refrigerant
handling, high-pressure system maintenance, leak detection, and environmental safety
protocols critical to professional HVAC/R practice and successful EPA Section 608
certification under 40 CFR Part 82 Subpart F and AIM Act Subpart C (ER&R Program,
effective Jan 1, 2026). Type II covers high-pressure and very high-pressure appliances:
refrigerants with liquid-phase saturation pressure between 170-355 psia and above 355
psia at 104F, including R-22, R-407C, R-404A, R-507, R-410A, R-32, R-454B, R-452B.
Answer Format
All correct answers appear in bold and cyan, accompanied by concise rationales explaining
safety/operational reasoning, code adherence, and why alternative options are less
appropriate.
Regulatory Update & Passing Score - 2026-2027
Official Proctored Type II Exam: 25 questions, 70% required to pass = 18 correct answers (72%). The
21/25 (84%) threshold applies ONLY to Type I open-book mail-in format. This document contains
exactly 25 exam-accurate questions aligning with authentic body-administered Type II length.
Current leak thresholds (per 2016 Rule and AIM Act ER&R Final Rule 2024, compliance Jan 1, 2026):
Comfort Cooling 10%, Commercial Refrigeration 20%, Industrial Process Refrigeration 30% per year,
applicable to 50+ lbs ODS and 15+ lbs HFC or substitute with GWP >53. Required evacuation per
EPA.gov table Sept 8, 2025: Very high-pressure 0 in Hg, High-pressure less than 200 lbs 0 in Hg, High-
pressure 200+ lbs 10 in Hg vacuum post-1993 equipment. Fines up to $44,539 per day per violation.
, Question 1:
Which definition best describes a high-pressure appliance under EPA Section 608?
A. An appliance that uses a refrigerant with liquid-phase saturation pressure below 45
psia at 104F
B. An appliance that uses a refrigerant with liquid-phase saturation pressure between
170 psia and 355 psia at 104F
C. An appliance that uses a refrigerant with liquid-phase saturation pressure between
45 psia and 170 psia at 104F
D. A small appliance manufactured, charged and hermetically sealed with 5 lbs or less of
refrigerant
Correct Answer: B. An appliance that uses a refrigerant with liquid-phase saturation
pressure between 170 psia and 355 psia at 104F
Rationale: EPA categorizes by saturation pressure at 104F per 40 CFR 82.152. Below 45 =
low-pressure Type III (R-123), 45-170 = medium-pressure (R-134a, R-12), 170-355 = high-
pressure (R-22, R-407C, R-410A, R-404A), above 355 = very high-pressure (R-13, R-23).
Option A is low-pressure, C is medium-pressure, D is Type I.
Question 2:
Which of the following refrigerants is classified as a high-pressure refrigerant covered
under EPA 608 Type II?
A. R-11
B. R-123
C. R-410A and R-22
D. R-600a isobutane
Correct Answer: C. R-410A and R-22
Rationale: Type II includes high and very high-pressure appliances such as R-22 HCFC, R-
407C, R-404A, R-507, R-410A, R-32, R-454B. R-11 and R-123 are low-pressure chillers Type
III. R-600a is hydrocarbon in domestic small appliances. EPA clarified R-410A is high-
pressure not very high-pressure as of current guidance.
