EPA 609 Certification 2026: Exam Questions, Passing Score, Cost & Where to Test

Audio from the Open Exam Hub video of the same name; the video shows the numbers and practice questions on screen.

EPA 609 certification explained: who needs it, the exam, passing score, cost and where to test. As of October 2026, the EPA requires anyone who repairs or services motor vehicle air conditioning (MVAC) systems for pay to be certified through an EPA-approved program; the EPA does not give the EPA 609 exam itself. One approved provider, MACS, lists a 25-question open-book online test, 84% to pass, at $24 to $29 on its pages (fees and formats vary by provider). Covers Section 609 vs 608 vs ASE A7, how to get certified, what the 609 exam covers, three EPA 609 practice test style sample questions, the refrigerant sales rules (2 lb small cans), whether the card expires, R-134a and R-1234yf, and the HVAC exam prep path after 609. Independent guide, not affiliated with the EPA or any certifying program.
