Abstract
A method of controlling a heating, ventilation and air-conditioning (HVAC) system includes measuring an ambient temperature and determining whether the ambient temperature is below a threshold temperature value. Responsive to a determination that the ambient temperature is below the threshold temperature value, measuring a condenser-fan cycle time of the HVAC system and setting a speed of the compressor based on the measured condenser-fan cycle time.
