HVAC Refrigerants and Clean Air Act
Course Highlights

This online engineering PDH course provides information relating to the safe handling, storage, recovery and disposal of refrigerants. This course also provides necessary information relating to the Federal Clean Air Act & EPA 608 guidelines.


In refrigerating systems, the fluid that absorbs heat and transfers it to a heat sink, usually with a phase change is called “Refrigerant”. Due to several environmental issues such as ozone layer depletion (ODP), global warming (GW) and their relation to the various refrigerants used, the refrigerant handling, storage and recovery has become one of the most important issues in recent times.


EPA Section 608 of the Clean Air Act is an extremely important law for the owners/operators of refrigerant-containing appliances and the HVAC technicians who service them. Section 608 prohibits individuals from intentionally or knowingly venting ozone-depleting substances, such as the chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) commonly found in refrigerants. Furthermore, Section 608 establishes guidelines for how refrigerants containing CFCs and HCFCs are collected and recycled. It also outlines the certification requirements for refrigerant recycling and recovery equipment, technicians who handle refrigerants, and individuals who reclaim refrigerants.


This 6 PDH online course is applicable to environmental engineers, HVAC engineers, technicians, O&M personnel, designers, facility managers, and HSE personnel working in the air-conditioning and refrigeration trades who are interested in familiarizing with the Clean Air Act and EPA 608 guidelines.
