The invention relates to a method for managing a reversible air-conditioning device for a motor vehicle, the device being configured to operate alternately in a cooling mode or in a heating mode, the device comprising an external heat exchanger, an internal heat exchanger, at least one compressor, and at least one expansion valve mounted between the external heat exchanger and the internal heat exchanger. The method comprises the following steps: a step of activating the compressor; a step of closing the expansion valve or valves; and a step of measuring overheating of the refrigerant fluid at the inlet of the compressor, comparing the measured value to a target overheating value and opening the expansion valve associated with the operating mode under consideration when the measured overheating value is greater than or equal to the target overheating value.
