The invention relates to the technical field of air conditioner devices, in particular to an air condition assist device electrical heating running method. The air condition assist device electrical heating running method uses a heat pump system and an auxiliary heating system. After the heat pump system is started, the auxiliary heating system is automatically started and stopped by constantly detecting indoor temperature. A default temperature range of single use of the heat pump system is set to range from -delta T to delta T, wherein T is given indoor temperature, delta T is upper and lower floating value of the given indoor temperature T, and when the indoor temperature is lower than or equal to the temperature -delta T, the auxiliary heating system is started for heating, and furthermore when the indoor temperature is larger than the temperature delta T, the auxiliary heating system stops the heating. The air condition assist device electrical heating running method can automatically control heating modes, preferentially uses a heat pump for the heating, saves energy resources, and simultaneously adjusts release heat of the auxiliary heating system according to the indoor temperature and the given temperature difference range, and thereby achieves optimal configuration of the heat, and is good in safety, stability and reliability.
