Refrigerant Handling (EPA 608)

It’s the law! To work on stationary air conditioners and refrigeration systems, you must be certified under Section 608 of the Clean Air Act.

ACCA and our partners, the Pennsylvania College of Technology, make it simple. As creators of the original and most popular EPA certification training programs and tests, ACCA has certified over 300,000 people.
