Sub-Zero appliance repair services in Charlotte
Expert Sub-Zero appliance repair for premium cooling systems
Sub-Zero refrigerators are known for their precise temperature control, dual refrigeration systems, and long-lasting engineering. However, when a Sub-Zero unit develops cooling issues, ice buildup, or a faulty sealed system, it requires a trained specialist — not general appliance repair.
Our technicians work with all Sub-Zero generations and configurations, including built-in Pro models, integrated columns, undercounter refrigerators, and wine preservation systems. We provide accurate diagnostics, genuine-quality parts, and long-lasting repairs tailored to high-end refrigeration technology.

Common Sub-Zero appliance problems
Sub-Zero units are premium and highly reliable, but they use complex components that require professional diagnostics. These are the most frequent issues we repair:
- Sub-Zero refrigerator not cooling or cooling unevenly
- Freezer warming up or losing temperature over time
- Ice buildup on evaporator coils
- Unit running constantly or making loud noises
- Ice maker not working or leaking
- Water leaking under the refrigerator
- Control panel or temperature display malfunctioning
- Wine cooler not holding steady temperature
Most of these problems require specialized tools and brand-specific troubleshooting, which our technicians are trained to perform.

Why Sub-Zero appliances break down
Sub-Zero refrigerators use advanced dual refrigeration, vacuum-sealed doors, and high-precision sensors. Failures can occur when any of these components are worn or obstructed. Common causes include:
- Evaporator coil corrosion (common in older Sub-Zero models)
- Faulty or weak compressors
- Refrigerant leaks in the sealed system
- Clogged or damaged condenser coils
- Failed evaporator or condenser fan motors
- Defective thermistors or temperature sensors
- Ice buildup restricting airflow
- Door gasket wear causing warm air intrusion
We identify the exact source of the issue and restore performance using professional Sub-Zero repair methods.
