An air conditioner has a controller (24) that controls the operation of a refrigerant circuit that has a compressor (16), a condenser (18), an expansion valve (20) or orifice tube, and an evaporator (14). The condenser receives a compressed refrigerant from the compressor and condenses the refrigerant to either a liquid phase or a saturated liquid-vapor phase. The condensed refrigerant is then passed through the expansion valve or orifice tube to expand the refrigerant and to delivery the refrigerant to the evaporator. When the compressor is first started, various sounds and vibrations are created that may be unpleasant to humans. Also, if the engine (12) is cold, then the compressor may have liquid refrigerant that can increase the torque needed to start the compressor. The controller pulses the compressor between ON and OFF operating states to reduce or eliminate these sounds and/or manage the start up torque of the compressor.
