Dispatched our Los Angeles County HVAC tech back to a business for approved repairs. Their refrigeration vault needed it's compressor replaced. And pumping down the system and cutting out the old compressor, our technician installed the new part, welding it back in place, replacing wiring and recharging the system. Replaced drier and sight glass as well. Tested all operations, walk-in cooler back online and no more issues to report.
