Upon arrival customer told me the ac was shutting down and ON. I put gauges on and the and the high side was really high. I took an amp drawl and the compressor is over amping a lot. The compressor is going bad. All fan are working good. I recommend on replacing the unit do to age but also quoted out a compressor. There is no guarantee that there is anything else wrong with system. Customer wants to think about it and call us back.
