How to Get EPA 608 Certification: 2026 Steps
Last checked October 20, 2026
EPA 608 certification is a federal requirement for most refrigerant work. Here's the path, step by step.
We sell practice, not the certification. Only an EPA-approved certifying organization can certify you.
Do you need it?
You need it if your work could be expected to release refrigerant while you maintain, service, repair or dispose of equipment. That covers most HVAC and refrigeration work (40 CFR 82.161(a)).
Two exceptions:
- Apprentices registered with the U.S. Department of Labor's Office of Apprenticeship (or a recognized state council) may work without it for up to two years. They must be closely and continually supervised by a certified technician (40 CFR 82.152, 82.161(a)(2)).
- Disposal only. People who only dispose of small appliances or vehicle A/C units don't need it.
Certification also matters at the supply house. Most refrigerant can only be sold to certified technicians or their employers (40 CFR 82.154(c)).
Step 1: Pick your type
| Type | Equipment |
|---|---|
| Type I | Factory-sealed small appliances with 5 lb or less |
| Type II | Medium-, high- and very high-pressure equipment, such as split systems and commercial refrigeration |
| Type III | Low-pressure equipment, mainly chillers |
| Universal | All of the above |
Every type also requires the Core section. If you aren't sure, aim for Universal. It's the same Core plus three 25-question sections.
Step 2: Study and practice
Each section has 25 questions, and you need 70%, or 18 correct (40 CFR Part 82, Appendix D).
Start with Core, since you can't be certified without it. Take a full practice test cold, study your weak topics, then retest.
Step 3: Choose a certifying program
EPA publishes the list of approved programs. Some test at sites around the country, and some offer remote testing online (EPA list of certification programs).
Compare price, retake rules, language options and whether you need to travel. Our cost comparison and online exam guide can help.
Step 4: Take the proctored exam
Types II, III and Universal are closed-book, proctored exams. The proctor checks a photo ID, such as a driver's license or passport (Appendix D).
Type I can be taken on site, and some programs offer it by mail. A mail-in Type I needs 84% and doesn't count toward Universal (Appendix D).
Step 5: Get and keep your card
The program must send your results within 30 days of the test, and issue a wallet card within 30 days (Appendix D).
Keep a copy of your certificate at your place of business. Hold on to it until three years after you stop working as a technician (40 CFR 82.161(a)(4)).
Section 608 credentials don't expire (EPA certification requirements). If you lose your card, contact the program that certified you.
