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 makes it simple. As creators of the original and most popular EPA certification training programs and tests, ACCA has certified over 300,000 people.

608 Made Simple

Contractors, ensure your new hires and incoming technicians are certified properly to handle refrigerant — not just in the required way, but in the right way. ACCA makes it easy.
