B) higher operating pressures
C) low operating pressures
D) reduced evaporator superheat

Question

Quizplus · Accepted Answer

An undercharged air conditioning system will have low operating pressures. This means that there is not enough refrigerant in the system to properly cool the air. This can also lead to reduced evaporator superheat, which can cause the compressor to work harder and potentially overheat. However, an undercharged system does not necessarily increase the possibility of floodback to the compressor, and it generally has lower, not higher, operating pressures.
