The air conditioning system can draw power from the utility power grid via an electrical line or from a battery. When the air conditioner is used during off peak hours, the air conditioner will draw power directly from the power grid. During peak usage, the air conditioner will be provided with power from the battery. The battery, in turn, is recharged from the power grid during off peak hours, such as during the night. In this way, the battery is kept fully charged and able to provide power during the peak period. The flow of the power to the air conditioner from the battery or line power is controlled by a timer switch. The flow of line power to the air conditioner or battery recharger during off peak hours is controlled by a recharge timer switch. The result is an air conditioning system reducing the strain on the power grid during peak usage and having an alternative power source, the battery, charged during off peak hours.
