Before refrigerant can be reused, it must be:

Refrigerant must be filtered and dried before it can be reused to ensure its purity and effectiveness in the cooling cycle. Over time, refrigerants can carry impurities such as moisture, acids, and debris that can accumulate in the system. Filtering removes particulates and contaminants, while drying eliminates moisture that can cause corrosion and operational issues in the system.

Using refrigerant that hasn’t been properly processed can lead to inefficiency, potential system damage, and reduced lifespan of the equipment. By ensuring that the refrigerant is clean and free of moisture, technicians can maintain the reliability and efficiency of the refrigeration system.

The other options involve processes that do not align with the standard procedures for refrigerant reuse. Heating and compressing, for instance, do not address the necessary steps for ensuring the refrigerant’s condition.
