MACS Section 609 Refrigerant Recycling and Recovery Certification Program
Effective 1/1/2018 Certification is required to purchase refrigerant
The fastest way to obtain a Section 609 certification is to take the online test

Since 1990, over one million technicians have achieved Section 609 certification through the MACS Worldwide Refrigerant Recovery and Recycling Technician Certification program. MACS created the first technician certification program for refrigerant recovery and recycling, and the program and the MACS organization were cited by name in the Clean Air Act of 1990 (Title VI, Section 609).
The Refrigerant Recovery and Recycling Program developed by MACS to meet requirements under Section 609 of the Clean Air Act was formally approved by the U.S. Environmental Protection Agency (EPA) effective August 13, 1992, 30 days after the publication of the final rule. At that time, the EPA advised MACS that all individuals voluntarily trained under the program since its inception would be considered properly trained and certified.
Through the years, MACS has led the way and developed and expanded the certification program to reflect industry changes in technology, service equipment and procedures, tools, alternative refrigerants and regulatory requirements. 
Periodically, the U.S. EPA requires all Section 609 Technician Certification Programs to update their programs, most recently to “incorporate information on three new alternatives found acceptable subject to use conditions in motor vehicle air conditioning under the Significant New Alternatives Policy (SNAP) program, HFO-1234yf, R-744 (CO2) and HFC-152a.”
MACS submitted the requested training materials for review, and on November 13, 2014, received notification from the U.S. EPA that “Mobile Air Conditioning Society (MACS) Worldwide has met the requirements of the update and satisfactorily submitted revised Section 609 training and certification materials. With this letter EPA confirms MACS Worldwide’s Section 609 Technician Training and Certification Program approval. MACS Worldwide will remain on EPA’s list of approved programs.”
In addition to meeting the requirements for Section 609 programs set by the U.S. EPA, MACS was also the first organization to certify its program to SAE International Standard J2845, “R-1234yf (HFO-1234yf) and R-744 Technician Training for Service and Containment of Refrigerants Used in Mobile A/C Systems.” The scope of this SAE standard notes, “The technician shall be trained to recognize which refrigerant is being handled, how to handle it safely and be equipped with the essential information, proper equipment and tools, which are unique to these refrigerants.” (See listing of the MACS program at and click on “Search.”)
