Returned to a San Jose CA diner to confirm status of the sandwich counter's compressor. Our refrigeration technician re-examined the unit, and the compressor may not need replacement but we will not be able to determine 100% until the start components are replaced.

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.

An air conditioning unit replacement was scheduled today at a vitamin store in San Jose California. The original unit was old when its compressor grounded, so the customer opted for replacement instead. The technicians met with the crane, had the old HVAC removed after disconnecting it and the new unit placed. Connected supply and returns, installed new drain lines and disconnect, secured system, replaced electrical. Ran and tested new unit, system is operational and site cooling again.
