Should EPA regulations change after a technician becomes certified, it is the responsibility of the technician to comply with these changes. The EPA also reserves the right to modify the test questions and/or require
new certification or recertification based on advancements in technology. The ESCO Institute will update this manual, as necessary, to reflect current EPA regulations and testing requirements.
Section 608 of the Clean Air Act requires all persons who maintain, service, repair, or dispose of appliances containing regulated refrigerants, be certified in proper refrigerant handling techniques as required by the
National Recycling and Emission Reduction Program. Regulated refrigerants currently include: CFC, HCFC, HFC, and HFO refrigerants.
If you maintain, service, repair, or dispose of appliances containing a regulated refrigerant, you must be certified.
