An air-conditioning control apparatus controlling a plurality of air conditioners calculates an adjustment time for adjusting a temperature of an area to be adjusted by the air conditioners to be controlled to between a desired temperature and an allowable temperature, generates a control schedule based on the adjustment time, and controls the air conditioners with the generated control schedule, instead of controlling with a preset stop time which is fixed, in order to bring the temperature around the air conditioners to the desired temperature. Thus, the air conditioners can be made to stop heat exchange before the desired temperature is reached, so that power consumption can be reduced.
