The invention relates to a dual-system air conditioner and a load control method and device thereof. The dual-system air conditioner load control method comprises the steps that under the condition that a first mainboard single system works, a first mainboard controls a load to work through a first load control circuit; and under the condition that a second main board single system works, a secondmain board controls the load to work through a second load control circuit, wherein the first load control circuit and the second load control circuit are both single conduction circuits, the conduction direction of the first load control circuit is the direction of the first mainboard to the load, and the conduction direction of the second load control circuit is the direction of the second mainboard to the load. According to the method, through the single conduction characteristic of the first load control circuit and the second load control circuit, when the single system is operated, onlythe corresponding mainboa
