How to Get EPA 608 Certification 2026: 5 Steps to Your Card

Steps to EPA 608 certification

Pick your type. Type I is for small appliances, Type II for high-pressure equipment such as split systems and heat pumps, Type III for low-pressure chillers, and Universal for all three.
Choose a program from EPA’s approved list. Its entries say which programs test nationwide, remotely or in Spanish, and which are only for their own employees.
Study the Core topics and the topics for your type. EPA doesn’t publish a study guide, so the topic list and the rules are your outline.
Take the test: in person with a proctor, online with a remote proctor, or, for Type I only, in a mail-in or open-book format.
Get your results and wallet card. The program has up to 30 days to send both.

What are the requirements for EPA 608 certification?

The regulation, 40 CFR 82.161 (Title 40 of the Code of Federal Regulations), asks one thing: pass a certification exam from an approved program for the kind of equipment you work on. It doesn’t set an age, a school level or a training course.

On test day the proctor has to check your identity with photo identification. EPA’s rules name a driver’s license, a government ID card, a passport or a military ID as examples. Registered apprentices and students in lab courses can work before they’re certified, under the conditions in the guide’s FAQ.

Where to take the EPA 608 test

EPA’s list gives each program’s headquarters, but EPA says many programs test all over the country and each one can tell you its locations. Mainstream Engineering’s testing locator finds proctors at stores: you buy the materials there, the store keeps your test, and you book a time with its proctor. The proctors for the Air Conditioning Contractors of America (ACCA) are vocational schools, manufacturers, utilities, contractors and local contractor associations.

You don’t have to travel at all if you choose a program that tests remotely.

Taking the test in Spanish, another language or orally

EPA’s rules encourage programs to give the test in other languages or allow a translator. Any program must give the test orally if you ask in writing at least 30 days before your test date and explain why. These programs are marked “Spanish available” on EPA’s list:
