A system is disclosed. The system includes a climate condition determination module that is configured to determine a climate condition associated with a vehicle based upon an external air temperature or a dew point temperature. The system also includes a compressor operational state control module that is configured to control a plurality of operational states of a variable displacement compressor of a heating, ventilation and air conditioning system within the vehicle. The compressor operational state control module is configured to cause the variable displacement compressor to selectively transition from a variable displacement operational state to a fixed displacement-like operational state when the climate condition exceeds a climate threshold to cause an evaporator of the heating, ventilation and air conditioning system to provide evaporator air having an air temperature corresponding to a target evaporator air temperature.
