Walk-In Cooler Refrigeration Repair and Leak Diagnosis in Austin TX

Performed commercial refrigeration diagnostic and repair service on a walk-in cooler refrigeration system at Finley’s in Austin TX.

Equipment serviced:

Copeland Compressor Model: RS70C1-PFV-213
Heatcraft Evaporator Model: LSC090AK
Refrigeration Design System Model: SSSM10

Returned onsite for continued diagnosis of the second walk-in cooler serving the food storage area. Upon arrival, the evaporator coil was found completely iced over, restricting airflow and preventing proper cooling performance.

Due to the evaporator location being installed tightly against the wall and product stored directly underneath, manual de-icing could not be safely performed. Compressor was shut off and evaporator fan motors were left running to allow the coil to thaw naturally before returning later to complete repairs and evaluation.

Services performed:

Cleared clogged drain line using Drain Solve
Cleaned heavily clogged condenser coil
Checked refrigerant pressures and system operation
Performed refrigerant leak inspection
Evaluated electrical wiring and breaker configuration

During inspection, several installation and system issues were identified:

Walk-in cooler system improperly wired using two separate 20-amp single-pole breakers
Condenser and evaporator circuits incorrectly tied together
Previous wiring modifications and crossed controls observed
Breaker failure occurred during service and was replaced by owner

Added approximately 4 lbs of customer-provided R22 refrigerant to restore cooling and clear the sight glass.

Leak inspection revealed a major refrigerant leak near the line set wall penetration between the condenser and evaporator. Findings are consistent with copper line rub-out damage inside the wall penetration area. Foam insulation prevented direct visual confirmation of the leak source.

Recommendations:

Replace refrigeration system and likely replace refrigerant line set
Install proper dedicated 208V power circuits for condenser and evaporator
Have licensed electrician correct breaker and control wiring configuration
