The EPA 608 certification is required by law for any technician who purchases or handles refrigerants. It covers safe handling, leak detection, recovery, and environmental regulations.

Type I covers small appliances (≤5 lbs refrigerant), Type II covers high-pressure systems, Type III covers low-pressure systems, and Universal covers all three. Most HVAC technicians pursue Universal certification.

You must score at least 70% on each section of the exam. The Universal exam has four parts: core, Type I, Type II, and Type III.

Type II & III Exam Tip: Certification is scope-limited. Type II certification does not authorize chiller work, and Type III certification does not authorize Type II work.

Neither

Question 3: A leak is found on a rooftop package unit, and refrigerant is escaping into the air outside. What type of equipment does this describe?

Type III
Type II
Could be either
Cannot be determined

Question 4: A leak is found on a chiller, and outside air is being pulled into the system instead of refrigerant escaping. What type of equipment does this describe?

Type II
Could be either
Cannot be determined
Type III

Question 5: A technician is called to a building with two separate cooling systems: a rooftop package unit for the office area and a large centrifugal chiller for the main lobby and labs. What certifications does this technician need to legally service both?

Type II only
Type III only
Core only
Both Type II and Type III

Question 6: True or False: Type II certification automatically includes Type III certification.

True
True, above a certain company size
False
True, if the technician has 10+ years of experience

Question 7: Which statement correctly matches equipment pressure to type?

Type II below atmospheric; Type III above atmospheric
Type II above atmospheric; Type III below atmospheric
Both above atmospheric
Both below atmospheric

Question 8: A technician needs to nitrogen-pressure-test a system as the standard method for finding a leak. Which type of equipment is this technician most likely working on?

Type III
Type II
Neither
Both equally, using identical procedures

Question 9: A technician plans to raise system pressure with hot water before checking for a leak. Which type of equipment is this technician most likely working on?

Type II
Neither
Type III
Both equally

Question 10: A technician recovers a large liquid refrigerant charge using push-pull recovery. Which equipment type is this most likely on?

Type III
Neither
Type II
Both equally

Question 11: A technician checks a purge unit's log as part of routine maintenance. Which equipment type is this technician working on?

Type II
Type III
Neither
Both equally

Question 12: True or False: A technician holding Universal certification can legally service both Type II and Type III equipment.

False
True, only with a supervisor present
False, Universal certification excludes Type III
True

Question 13: A walk-in cooler at a grocery store needs its compressor replaced. Refrigerant must first be recovered and the correct vacuum level reached. What certification does this job require?

Type II
Type III
Either one
No certification

Question 14: During an inspection, a technician finds that a chiller has an unusually high level of non-condensable gases despite the purge unit running normally. What should the technician suspect, and what type of equipment is involved?

Overcharge; Type II rooftop unit
A broken thermostat; Type I furnace
Low oil level; Type II heat pump
A leak letting in extra air; Type III chiller

Question 15: True or False: The 10 in. Hg / 15 in. Hg evacuation levels based on charge size apply specifically to Type II equipment.

False
True, but also to Type III chillers
True
False, they apply only to Type I

Question 16: Which equipment type experiences moisture intrusion as an ongoing operational concern requiring a dedicated device, the purge unit, to manage it?

Type II
Neither
Type III
Type I

Question 17: A technician with only Type III certification is asked to fix a leak on a rooftop package unit. What should they do?

Proceed, since they are certified for refrigerant work
Decline, since Type III certification does not cover Type II equipment
Proceed, but only evacuate to 10 in. Hg
Proceed, but only if supervised by anyone

Question 18: Which of these equipment types would use UV dye as a leak detection method in the standard way described for this exam?

Type III
Neither
Only Type I
Type II

Question 19: A technician needs to service both a rooftop unit and a chiller at the same commercial building, but their license only covers Type II. What must they do regarding the chiller?

Arrange for a Type III certified technician to handle the chiller
Service it anyway since it is at the same building
Use Type II procedures on the chiller since it is similar equipment
Refuse to service either system

Question 20: True or False: Both Type II and Type III certification exams are closed-book only.

True
False
True, except Type III which allows open-book
True, except Type II which allows open-book

Question 21: A technician compares the passing scores for the Core, Type I, Type II, and Type III exams. What do all four have in common?

All require 70% to pass
All require 90% to pass
Only Type III requires 70%
Passing scores vary randomly by state

Question 22: Which equipment type would a technician expect to service using vapor, liquid, or push-pull recovery methods?

Type II
Type III
Neither
Only Type I

Question 23: A technician needs Universal certification. Which four parts must they pass?

Core, Type I, Type II, Type III
Core, Type II, Type III only
Type I, Type II, Type III only
Core and Type III only

Question 24: True or False: A technician can pick and choose which certification exams to take based on the equipment they plan to service.

False
True, but only for Type II
True
True, but only for Core

Question 25: Which single fact best explains most of the differences between Type II and Type III procedures covered in this test?

Type III equipment is newer
Type II equipment runs above atmospheric pressure, and Type III equipment runs below it
Type II equipment is always bigger
Type III equipment does not use refrigerant

Study Tip: The EPA 608 exam is closed book. Memorize: recovery is required before opening any refrigerant system. Venting refrigerant is illegal. Know the ODP and GWP values for R-22, R-410A, R-134a, R-32, and R-454B.
