Overcharging a refrigerant system can cause liquid refrigerant to return to the compressor, resulting in damage or failure. This is because the compressor is not designed to handle liquid refrigerant, and the excess liquid can cause mechanical damage to the compressor’s internal components. Overcharging also leads to increased energy consumption, reduced system efficiency, and potential system breakdowns. In addition, overcharging can cause the system to operate at higher pressures, leading to increased stress on the system’s components and further reducing its lifespan.
