An HVAC system includes a variable-speed compressor which compresses refrigerant flowing through the HVAC system, a blower which provides a flow of air through the HVAC system at a controllable flow rate, and a controller communicatively coupled to the variable-speed compressor and the blower. The controller receives a demand request which includes a command to reduce power consumption by the HVAC system. In response to receiving the demand request, a speed of the variable-speed compressor is decreased and the controllable flow rate of the flow of air provided by the blower is adjusted.

An air conditioner includes an outdoor unit, a plurality of indoor units, a plurality of detecting units, an operating device that receives an instruction on use of all prediction results obtained for all of a plurality of spaces, a determining circuitry, and a deciding circuitry. The detecting circuitries each detect a state relating to temperature of an associated space. A prediction result obtained for each of the spaces is a predicted temperature of the space associated with one of the detecting circuitries a predetermined time after a detection result is obtained by the one of the detecting circuitries, which is predicted on the basis of the detection result. When all the prediction results are determined not to be the same, the deciding circuitry determines how air conditioning is to be performed on the basis of part or the whole of all the prediction results in accordance with an instruction received by the operating device.
