1. A method of controlling indoor air temperature of a heat pump system, the method comprising:
(a) determining, during a heating mode, an outdoor coil temperature of an outdoor heat exchanger and a speed of a compressor of a heat pump system;
(b) determining, during the heating mode, a target indoor coil temperature of the indoor coil based on the outdoor coil temperature and the speed of the compressor; and
(c) adjusting, during the heating mode, a speed of air flowing across the indoor coil based on a difference between a current indoor coil temperature and the target indoor coil temperature to reduce the difference between the current indoor coil temperature and the target indoor coil temperature.
