Section 609 Certification FAQ

The warmer months will soon be here and once again the phones at the MACS Worldwide office will ring as questions arise about Section 609 of the U.S. Clean Air Act and technician certification.

Technician Training and Certification: Technicians who repair or service HFC-134a MVACs must be trained and certified by an EPA approved organization. To be certified, technicians must pass a test demonstrating their knowledge in these areas. A technician already trained and certified to handle CFC-12 does not need to be recertified to handle HFC-134a.

Recordkeeping: Service shops must maintain records of the name and address of any facility to which refrigerant is sent. Service shops are also required to maintain records (on-site) showing that all service technicians are properly certified.

Certification: Service shops must certify to EPA that they have acquired and are properly using approved refrigerant recovery equipment. Note that this certification is a one-time requirement, so that if a shop purchased a piece of CFC-12 recycling equipment in the past, and sent the certification to EPA, the shop does not need to send a second certification to EPA when it purchases a second piece of equipment, no matter what refrigerant that equipment is designed to handle.

Sales: There is no restriction on the sale of HFC-134a, so anyone may purchase it.
