1. A heating, ventilation, and air conditioning (HVAC) system configured to regulate a temperature of a space, the HVAC system comprising:
means for compressing a refrigerant used to cool air provided to the space;
a controller communicatively coupled to the means for compressing the refrigerant, the controller configured to:
determine that a demand response time period is starting at a start time, wherein the demand response time period is a future period of time during which a reduction in energy consumption by the HVAC system is requested;
after determining that the demand response time period is starting at the start time, determine an operation schedule indicating alternating portions of the demand response time period during which the means for compressing the refrigerant is to be turned off and turned on; and
at the start time of the demand response time period, begin operating the means for compressing the refrigerant according to the determined operation schedule.
