1. A system, comprising:
a circulation unit comprising a fan motor;
a refrigeration unit comprising a compressor;
a controller operatively coupled to the circulation unit and the refrigeration unit, and wherein the controller is configured to
determine a current draw associated with at least one of the motor and the compressor;
compare the current draw to a current threshold; and
iteratively adjust the speed of operation of at least one of the motor or the compressor in response to the current draw satisfying the current threshold, wherein iteratively adjusting the speed of operation is carried out alternately by the controller such that the controller adjusts at least one of the motor or the compressor in a first iteration and adjusts the other of the motor or the compressor in a second iteration.
