Setpoint Services completed an emergency commercial walk-in cooler repair at Domino's Pizza, located at 11211 E US Highway 290, Manor, TX 78653, after the restaurant reported the walk-in cooler was no longer maintaining safe operating temperatures. Initial diagnostics during an after-hours emergency service call found the refrigeration system operating with a low refrigerant charge. The condenser coil was heavily contaminated and was thoroughly cleaned to restore airflow and improve heat rejection. An initial 1 pound of refrigerant was added using the remaining refrigerant available on the service truck; however, additional refrigerant was required to complete the repair, so a return visit was scheduled for the following day.

During the return visit, Setpoint Services rechecked system performance and found operating pressures of 50 PSI suction and 280 PSI discharge, while the liquid line sight glass continued to flash, confirming the system was still low on refrigerant. An additional 2 pounds of refrigerant were added, restoring the proper system charge. Final operating pressures stabilized at 60 PSI suction and 320 PSI discharge, and the sight glass became full and clear, confirming a solid liquid refrigerant column. The walk-in cooler was monitored until it successfully pulled the box temperature back down to normal operating conditions.

Although cooling performance was fully restored, the low refrigerant condition indicates an active refrigerant leak within the system. Setpoint Services recommended scheduling a comprehensive leak search and repair to locate the source of the refrigerant loss and prevent future breakdowns, repeated refrigerant charges, and additional emergency service calls. The walk-in cooler was operating normally at the time of departure.
