A method of displaying air-conditioning management information including selecting an extracting position corresponding to a specific room for a layout image of a floor having a plurality of rooms, displaying a partial image extracted from the layout image of the floor having the plurality of rooms such that the partial image shows the specific room at the extracting position together with operating-state data on at least one air conditioner assigned to the specific room, and shifting the extracting position in units of rooms. Correspondingly, an air-conditioning management apparatus includes an image storage device in which a layout image of the floor having a plurality of rooms is stored, an image display extracting device which selects an extracting position and extracts from the layout image a partial image based on the extracting position and corresponding to a specific room, an image display device which displays the partial image together with operating-state data on at least one of the air conditioners assigned to each room, and an extracting-position shifting device which shifts in units of rooms the extracting position of the partial image to be extracted from the layout image.
