1. A method of mitigating liquid-refrigerant migration using a processor, the method comprising:
receiving one of a heating-demand call and an end-defrost call;
determining a requested compressor speed responsive to the receiving step;
comparing a requested compressor speed of a variable-speed compressor to a pre-defined threshold;
responsive to a determination that the requested compressor speed is not greater than the pre-defined threshold, operating the variable-speed compressor at the requested compressor speed;
wherein the operating step is performed for a pre-defined time period;
before expiration of the pre-defined time period, the comparing step is repeated;
responsive to a determination at the repeated comparing step that the requested compressor speed is greater than the pre-defined threshold, operating the variable-speed compressor at the first compressor speed that is less than the requested compressor speed; and
responsive to a determination at the repeated comparing step that the requested compressor speed is not greater than the pre-defined threshold, operating the variable-speed compressor at the requested compressor speed.
