EPA certification is required to _____.

EPA certification is required to both service R-12 A/C systems and purchase R-12 refrigerant due to the regulations established under the Clean Air Act. This act was enacted to protect the environment from harmful substances, specifically ozone-depleting substances like R-12, which is a chlorofluorocarbon (CFC).

To service R-12 systems, a technician must demonstrate sufficient knowledge and skills in handling refrigerants while adhering to environmental safety protocols. This includes proper recovery, recycling, and disposal of the refrigerant to minimize emissions. Additionally, purchasing R-12 requires certification to ensure that individuals who acquire this refrigerant are trained in its proper use and management, thereby reducing the chances of environmental harm.

Obtaining EPA certification ensures that technicians have received the necessary training and understand the regulations concerning ozone-depleting refrigerants, contributing to safe and compliant practices in the HVAC industry.
