EPA 609 Practice Test (Adaptive Mock)
Section 609 certification lets you service motor vehicle air conditioning for pay and buy small cans of regulated refrigerant. Each attempt draws 15–20 questions and adapts its difficulty to your last score.

15–20 Questions Drawn From 150

How This Practice Test Works
- Each attempt draws 15–20 questions at random from our pool of 150 and shuffles the answer order. Score 80% or more and the next test moves up a difficulty level; under 50% and it eases back.
- After every answer you see an explanation and the 40 CFR 82 Subpart B and EPA MVAC reference behind it.
- We use 70% as a practice target. Each EPA-approved program, such as ASE, MACS or ESCO, sets its own test format and pass mark.
- There is no sign-up. Your level is saved only in this browser.
These are original questions written by our editorial team from the published 40 CFR 82 Subpart B and EPA MVAC. They are not real exam questions. Each question cites the 40 CFR 82 section or EPA MVAC page behind it. EPA does not endorse Trade Exam Hub.
