To achieve a reduction in power consumption by allowing a plurality of air conditioners to communicate with each other and thereby leveling their air-conditioning capacities with no load variations involved by temperature variations. An air-conditioning apparatus 100 may include a plurality of air conditioners and a computing section for control, where each air conditioner includes an indoor unit and an outdoor unit that form a closed refrigeration cycle. The indoor units of the plurality of air conditioners are installed in an area to be air-conditioned. The computing section for control may allow the plurality of air conditioners to communicate with each other, thereby leveling their air-conditioning capacities based on air-conditioning load detected by each air conditioner.
