206 Trinity St, Unit 110 Austin, TX 78701
Setpoint Services completed a commercial walk-in cooler refrigeration repair at Taqueria De Diez Downtown Austin, located at 206 Trinity St, Unit 110, Austin, TX 78701. The customer reported the walk-in cooler was no longer maintaining the desired box temperature. Inspection of the Heatcraft refrigeration system revealed a low refrigerant charge and a condenser coil heavily restricted by dirt and debris, reducing heat transfer and overall system efficiency.
Our technician thoroughly cleaned the condenser coil using commercial coil cleaner and water to restore proper airflow and heat rejection. The refrigeration system was then recharged with 4 pounds of R-22 refrigerant, restoring the proper operating charge. After charging, the liquid line sight glass cleared, confirming a full liquid column. Final operating conditions measured 45 PSI suction pressure, 260 PSI discharge pressure, and a clear sight glass, verifying normal refrigeration performance had been restored.
During the repair, it was determined that the amount of refrigerant required indicates a significant refrigerant leak within the system. Based on the age and condition of the equipment, the evaporator coil is the most likely source of the leak. Because this refrigeration system operates on R-22 refrigerant, which has been phased out and is increasingly expensive and difficult to obtain, Setpoint Services recommended replacing both the walk-in cooler condensing unit and evaporator coil. A complete system replacement proposal will be provided to the customer.
