What action should technicians take regarding old refrigerant types?

Technicians must properly recover and dispose of old refrigerant types according to regulations to ensure environmental protection and compliance with laws governing refrigerant management. Older refrigerants, such as R-12 and R-22, are often ozone-depleting substances or have high global warming potential. Therefore, it is both legally mandated and environmentally responsible to handle them safely.

When technicians recover old refrigerants, they prevent these substances from being released into the atmosphere, which can contribute to climate change and ozone layer depletion. Proper disposal methods may include recycling and reclaiming the refrigerant or sending it to a facility that can manage it safely.

Using old refrigerants until they run out poses risks, as the older refrigerants not only harm the environment but also may not be compatible with modern equipment. Immediate replacement with newer versions without following proper procedures could also lead to violations of regulations. Venting refrigerants is illegal and harmful, making it essential for technicians to adhere to the correct recovery methods.
