Issue

The unit was no longer maintaining proper temperatures due to sealed-system failure and reduced cooling performance.

The Challenge

Because this is a built-in Sub-Zero, replacement often involves cabinetry modifications, higher overall cost, and longer downtime. Restoring the unit was the better option.

Repair Performed

We completed a full cooling system replacement, including key sealed-system components. The system was rebuilt, pressure-tested, evacuated, and charged to specification to restore proper performance.

  • Sealed-system components replaced as required
  • System pressure-tested and leak-checked
  • Evacuated and charged to specification
  • Cooling performance verified after repair

Result

Stable, reliable cooling was restored and confirmed. The customer avoided replacing a high-end built-in refrigerator and extended the life of a classic Sub-Zero.
