Section 609 Certification

What is Section 609 Certification?

Any person who repairs or services a motor vehicle air conditioning (MVAC) system for consideration (payment or bartering) must be properly trained and certified under section 609 of the Clean Air Act by an EPA-approved program. The program offered by MACS is EPA-approved.

EPA-approved technician training and certification (TT&C) programs provide education on the proper use of MVAC servicing equipment, the applicable regulatory requirements, the importance of refrigerant recovery, as well as the effects of improper handling of refrigerants on the ozone layer and climate. To be certified, technicians must be trained by an EPA-approved program and pass a test demonstrating their knowledge in these areas.

Section 609 certification is a requirement of the United States Clean Air Act of 1990. It is a requirement for purchasing more than two pounds of R-12,  R-134a and R-1234yf refrigerant. 

The cost for a MACS Section 609 test is $20 per test. Payment must be made before a test will be issued online or for home study. You have the options of taking the Section 609 certification test online here at the MACS website, or you may order a home study test. 

MACS can also provide onsite classes for Section 609 certification. To learn more about setting up a class call 215/631-7020 and dial "0" or e-mail
