How the Exam Works
What You Are Studying For
EPA Section 608 certification is required by federal law before you may handle refrigerants. Here is how the exam is actually put together.
01
Core is mandatory
Every certification path starts with Core: regulations, refrigerant fundamentals, recovery, cylinders, leak detection, and safety. You cannot earn any Type without it.
02
Pick your Type
Type I is small appliances, Type II is high-pressure equipment — the bulk of HVAC work — and Type III is low-pressure chillers. Each is a separate 25-question section.
03
Score 70% on each
Sections are scored independently, so 90% on Core will not rescue a 60% on Type II. The exam is proctored and open-book — bring your study guide.
04
Certified for life
Section 608 certification does not expire and requires no continuing education. Keep proof of certification at your place of business.
This is study material, not the exam
These questions are written from the published rule in 40 CFR Part 82, Subpart F and standard refrigerant-handling practice. They do not reproduce exam content. Rules change — verify anything that surprises you against a current EPA-approved study guide before you test.

Key Takeaways

The EPA Section 608 exam has four sections — Core, Type I, Type II, and Type III — each 25 multiple-choice questions requiring 70% to pass. Everyone takes Core; passing all three Types earns Universal certification. The exam is open-book, costs roughly $20–$40, and the certification never expires.

  • Core: required for every certification path
  • Type I: small appliances (5 lbs or less, factory-sealed)
  • Type II: high-pressure systems — most residential and commercial HVAC
  • Type III: low-pressure centrifugal chillers

FAQ
EPA 608 Practice Test Questions
Is this EPA 608 practice test really free?
Yes — all four sections, every question, and every explanation are free with no account and no email required. You can retake each section as many times as you want, and each attempt draws a different randomized set.
How is the EPA 608 exam structured?
The exam is split into four sections. Core covers material every technician needs and must be passed by everyone. Type I covers small appliances, Type II covers high-pressure equipment such as residential and commercial air conditioning, and Type III covers low-pressure centrifugal chillers. Each section is 25 multiple-choice questions and requires 70% to pass. Passing Core plus all three Types earns Universal certification.
What score do I need to pass EPA 608?
Seventy percent — 18 correct out of 25 — on each section independently. A strong Core score does not offset a failing Type score, which is why practicing the Type section you actually need matters as much as practicing Core.
Is the real EPA 608 exam open book?
Yes. The proctored exam is open-book, so you may bring your study guide. That is exactly why the questions test whether you know where the rules live and what they mean, rather than whether you memorized dates — and why every answer here comes with an explanation instead of a bare answer key.
Which EPA 608 certification should I get?
Universal, if you can. It requires passing Core plus all three Type sections at one sitting or across attempts, and it removes every scope limit on the refrigerant work you can legally perform. If you are choosing just one Type, Type II covers the residential and commercial air conditioning work most HVAC technicians do every day.
How much does the actual EPA 608 exam cost?
Typically $20 to $40 through an EPA-approved certifying organization, and many HVAC training programs include the exam fee in tuition and proctor it on campus. Certification never expires once earned.
