What does 'A/C recharge' refer to?

• A. Draining refrigerant from the system
• B. Adding refrigerant to the system
• C. Cleaning the evaporator coil
• D. Replacing the compressor

Answer: (B)

A/C recharge refers specifically to the process of adding refrigerant to an air conditioning system. Over time, refrigerant can escape due to leaks or normal wear and tear, leading to decreased efficiency and performance. When the refrigerant level is low, it is necessary to recharge the system to ensure it operates optimally. Recharging usually involves recovering any remaining refrigerant, measuring the system's refrigerant pressures, and then adding the appropriate type and amount of refrigerant as specified for the system. This not only helps restore the system's cooling power but also ensures that it runs efficiently and safely. The other choices involve actions that do not define the recharge process. Draining refrigerant is a separate procedure typically done during repairs or maintenance, cleaning the evaporator coil pertains to maintaining airflow and system cleanliness rather than refrigerant levels, and replacing the compressor involves replacing a core component of the system that may be malfunctioning, which is unrelated to the recharge process itself.
