ABSTRACT OF THE DISCLOSURE A mobile air-conditioner charging station is disclosed which has a reluctance-type weighing scale on which are mounted reservoirs of both lubricant oil and refrigerant. A computer module reads the weight loss of the combined reservoirs as, first, the oil is charged into the air- conditioner and then, sequentially and automatically, the refrigerant is charged into the air-conditioner. Each charging cycle is completed when the computer module senses, by a plurality of discrete readings of the scale at timed intervals, that a pre-selected magnitude of weight loss has occurred and has been maintained.
