When a refrigeration compressor has developed a high head pressure as a result of a refrigerant overcharge, what should be done to compensate for or to correct this situation?

Correct Answer: Option D — remove some refrigerant from the system

An overcharge of refrigerant floods the condenser coils with liquid, drastically reducing effective heat transfer surface area and spiking head pressure. The excess refrigerant must be physically recovered and removed into a dedicated recovery cylinder to normalize system pressures.
