A diner in San Jose, California, requested service for both their air conditioner and a sandwich station. Our local technician confirmed the A/C was working well, but needed its thermostat reprogrammed. Moved on to the sandwich table and found it running at 59 degrees, low on refrigerant. The second box was at 87 degrees, with it's compressor pulling a vacuum on the low side and empty of refrigerant. The compressor had been replaced recently by another contractor. Will need to perform a full leak search and repair on both boxes, as well as install new liquid line driers.
