A refrigeration system including a refrigeration circuit and a controller. The refrigeration circuit includes a plurality of variable capacity compressors arranged in parallel to compress a refrigerant. A second variable capacity compressor is started after a first variable capacity compressor. An evaporator defines a load while evaporating the refrigerant to refrigerate a space within a predetermined temperature range. The controller is programmed to control the operation of the plurality of variable capacity compressors to match the capacity of the plurality of variable capacity compressors to the load by increasing the capacity of the last compressor in the queue of running compressors when the capacity of the plurality of variable capacity compressors is lower than the load and by decreasing the capacity of the first compressor in the queue when the capacity of the plurality of variable capacity compressors is higher than the load.
