A system includes a power source, a sensor to detect data, and a HVAC system having a compressor to compress vapor refrigerant and a fan to blow conditioned air into a cabin of the vehicle, the compressor and the fan both designed to operate using a portion of the power generated by the power source. The system further includes an ECU to predict that the vehicle will accelerate or decelerate based on the data, to decrease power provided to the compressor and increase power provided to the fan when the ECU predicts the acceleration in order to reduce total power provided to the HVAC system and to reduce variance in total noise and vibration generated by the HVAC system, and to increase power to the compressor when the ECU predicts that the vehicle will decelerate in order to increase the total power provided to the HVAC system.
