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. Accordingly, a ratio of the first flow rate to the decreased tonnage of cooling is increased to a predefined value, and a power consumption of the HVAC system is decreased by at least a predefined percentage associated with the demand request.
