Technicians receiving a passing grade on a small appliance examination are certified to recover refrigerant during the service or repair of small appliances, such as refrigerators, freezers, and air conditioning units. This certification ensures that they are knowledgeable about safe refrigerant handling practices and environmental regulations. Proper recovery of refrigerants is crucial to prevent harmful emissions and protect the ozone layer.
All devices used for refrigerant recovery must be certified by the EPA. If the device was manufactured before November, 1993, It must be capable of recovering 80% of the refrigerant in the appliance. If the device was manufactured after this date, it must be capable of recovering 90% of the refrigerant.

Before opening or disposing of an appliance, any refrigerant classified as a controlled substance, such as those included in the Montreal Protocol (like CFCs, HCFCs, and HFCs), must be recovered. This is essential to prevent environmental harm and comply with regulations. Refrigerants must be properly recovered using certified recovery equipment to ensure safe handling and disposal. Always consult local regulations for specific requirements regarding refrigerant recovery.

Finally, perform a thorough leak check to ensure complete removal of refrigerant before disposing of the unit.
