What type of refrigerants does the EPA 609 certification cover?

The EPA 609 certification specifically covers refrigerants used in mobile air conditioning systems, including CFCs (chlorofluorocarbons), HCFCs (hydrochlorofluorocarbons), HFCs (hydrofluorocarbons), and blends of these substances. This certification is essential for technicians who work with motor vehicle air conditioners to ensure they understand the proper handling, recovery, and recycling of these refrigerants.

CFCs and HCFCs are substances that have historically been used in a variety of refrigeration and air conditioning applications, but due to their ozone-depleting properties, they are being phased out in favor of HFCs and hydrocarbon blends, which have a lower impact on the ozone layer.

By covering a broad range of refrigerants and blends, the EPA 609 certification enables technicians to be well-prepared for the variety of refrigerants they may encounter in modern mobile air conditioning systems, ensuring compliance with environmental regulations and promoting best practices in handling refrigerants.
