Walk-In Cooler Refrigerant Leak Repair in Little River Academy, TX

Service Date: April 10, 2026 — Little River Academy, TX On April 10th, Setpoint Services technician Han Li responded to a commercial facility in Little River Academy, TX, where a Norlake walk-in cooler had completely lost its refrigerant charge. A thorough inspection revealed a major refrigerant leak at the base of the receiver — a critical component in the refrigeration circuit responsible for storing liquid refrigerant before it reaches the metering device.

Diagnosis: Full Refrigerant Loss from a Failed Receiver

The affected unit was a Norlake walk-in cooler evaporator (Model CPF100DC-A, Serial 13121631) operating on R404A refrigerant. Upon arrival, Han Li found the system had lost its entire charge, leaving the cooler unable to maintain safe storage temperatures. After confirming the leak source at the receiver, a complete repair plan was executed to restore the unit to proper operation.

Walk-In Cooler Repairs Performed

• Recovered any remaining refrigerant from the system
• Replaced the failed receiver responsible for the leak
• Replaced the liquid line filter drier to eliminate moisture and contaminants
• Pressure-tested the system with nitrogen to confirm no additional leaks
• Performed a deep vacuum (triple evacuation) to ensure the system was moisture-free
• Recharged the system with R404A refrigerant to factory specifications
• Verified proper system operation, pressures, and temperatures before leaving the site

Walk-In Freezer: Additional Assessment

During the same service visit, Han Li also evaluated the walk-in freezer on site (Model CFB075DC-A, Serial 13121613, R404A). The freezer was showing signs of restricted or improper refrigerant flow consistent with a failing thermostatic expansion valve (TXV). A recommended scope of work was developed to include TXV replacement, filter drier replacement, nitrogen pressure testing, deep vacuum, and refrigerant recharge — ensuring both refrigeration units on the property would be operating at peak efficiency.
