The invention relates to intelligent air conditioners, and discloses a method for pre-appointing starting of an intelligent air conditioner. The problems caused by the fact that in the traditional technology, the timing starting pre-appointing manner is adopted in an intelligent air conditioner are solved. The method comprises the steps that A, an electronic map tool is downloaded on a mobile terminal and used for obtaining the current position information of a user; B, the user sets the house address, and the house address is synchronized to a server; C, the user assigns the homing manner before starting the intelligent air conditioner starting pre-appointing function, and the home arrival duration threshold value T is set; D, after the intelligent air conditioner starting pre-appointing function is started, the duration needed for the user to go home from the current position is comprehensively calculated according to the current position information of the user, the house address information and the homing manner selected by the user, and the duration is compared with the home arrival duration threshold value T, wherein if the duration needed for the user to go home from the current position is smaller than or equal to the home arrival duration threshold value T, the step E is executed, and if the duration needed for the user to go home from the current position is larger than the home arrival duration threshold value T, the step D is executed; and E, a starting instruction is sent to the intelligent air conditioner, and the appointment is ended. The method is suitable for starting pre-arranging of the intelligent air conditioner.
