Who Must Be Certified
EPA approved certification testing is required for any person who may perform service, maintenance, repair or recovery work on a refrigerant containing circuit. AES technicians and Contractor technicians shall service only equipment for which they are certified.
EPA Certification
The required type of certification testing depends on the type of refrigerant being used and the size of the system being serviced. The types of required certification identified by the Clean Air Act Amendments Section 608, stationary equipment are:
- High- and very-high-pressure equipment Type II
- Low pressure equipment Type III
- All types Universal Type IV (Does not include motor vehicles)
It is recommended that the Division Refrigerant Supervisor provide an annual refresher training session for in-house technicians to obtain technician input on subjects, utilize manufacturer's training and at minimum cover safety issues, alternative refrigerants, servicing procedures, federal, state and local regulations.
Service technicians must be prepared to do the following if an EPA inspector or the Division Refrigeration Supervisor is on site:
- Present their certification cards.
- Recite the required recovery vacuum levels for the refrigerants being used at the location where they are working.
- Know the leak trigger rates for the over 50 pound EPA equipment classifications.
- Demonstrate the proper use of a recovery unit and validate that they perform leak tests on their recovery units, and can calibrate their gauges.
