The present invention relates to a cooling and heating system for a commercial vehicle, which carries out cooling and heating according to the traveling state of a vehicle by applying a mechanical compressor and an electric compressor to the commercial vehicle, and a control method thereof. The cooling and heating system includes a cooling device that is driven in cooperation with an engine to constitute a refrigeration cycle for compressing, condensing, expanding, and evaporating refrigerant to cool the interior of the cab of a commercial vehicle; an electric compressor disposed in parallel with the mechanical compressor provided in the cooling device; a controller for controlling the driving of the mechanical compressor and the electric compressor based on the traveling state of the vehicle, the state of a battery, and an engine load ratio; an auxiliary heater for heating a bed; and an auxiliary heater control module for driving the auxiliary heater to heat the bed in a cold state and a no-load state at the initial stage of vehicle startup through communication with the controller. According to the present invention, the interior of the cab can be cooled by selectively using the mechanical compressor and the electric compressor in accordance with the engine driving state, the battery state, and the engine load ratio, and the heating device can drive the auxiliary heater for heating in connection with the auxiliary heater until the cooling water temperature rises to the temperature at which heating is normally performed.
