Section 609 Certification is mandated by the U.S. Clean Air Act of 1990. Since 1992, technicians must be certified to recover and recycle refrigerant and to purchase R-12. From January 1, 2018, this also includes purchasing two pounds or more of refrigerants. Displaying a Section 609 card is required before purchasing refrigerant.

Refrigerants covered are R-12, R-134a, R-152a, R-744 (CO₂), and R-1234yf.

Technicians can take the Section 609 Class & Certification in person or online.


In-person classes can be scheduled in our classroom. Or, for groups of 4 or more students, we will teach at your facility (anywhere in the Phoenix Metropolitan area). The cost for in-person training is $75.00. For more information or to schedule your class, please contact us .


Online training is $24 and can be taken any time from MACS. This makes it accessible anywhere via computer or tablet.

The test consists of approximately 25 multiple-choice questions. If you purchase an online test package, we recommend completing the test within two weeks, ideally in one sitting. A practice test is available.


Our in-person classes also offer the opportunity to review the MACS study guide with our knowledgeable test proctors. Our classes are designed to help every technician succeed and don’t have any specific time limit.

A score of 84 or higher is required to pass, which equates to missing 4 or fewer questions. Taking the practice test beforehand is strongly recommended.

Online Test: You can retake the test for $24. We recommend taking the practice test to ensure a passing score.


In-Person Training & Testing: If a class needs to be repeated, the cost is $50.00

To access your online Section 609 test, log into your MACS account. From there, click on the button on the left side of the screen that says “View My Tests & Courses”.

Your certification card will be mailed within 24 hours of passing the test and should arrive within three weeks. A temporary certificate can be printed immediately.

If you lose your card, request a reprint from Air Components for $12. Only certifications issued by Mac’s or IMACA can be reprinted.

No re-certification is required if you were certified since 1991. However, re-certification is recommended for those servicing R-1234yf vehicles.

Yes, technicians can be fined up to $40,000 per day for non-compliance.
