Cooling unit not cooling / temperature rising Cellar temperature above set point, wine at risk | $240–$460 + parts per diagnosis | Condenser coil cleaning (often the fix — no parts needed), refrigerant check, thermistor, condenser fan, evaporator fan. Full system assessment before any parts quoted. |
Condenser coil cleaning & service Annual maintenance or restricted airflow diagnosis | $180–$280 No parts needed | Deep condenser coil cleaning, airflow verification, system performance check. In LA dry climate, annual cleaning prevents premature compressor failure. Often the root cause of apparent cooling unit failure. |
Compressor failure Cooling unit confirmed not running or running but not cooling | $320–$560 + compressor + refrigerant recharge | Full compressor replacement with refrigerant recharge. EPA-certified technician required. We assess repair vs. replace economics on the cooling unit before proceeding on older units. |
Refrigerant leak System losing refrigerant, gradual cooling loss | $280–$460 + refrigerant + leak repair | Leak detection, leak repair, refrigerant recharge. EPA-certified technician. Refrigerant quoted separately as a line item — you see the cost clearly. |
Temperature control / thermostat failure Temperature fluctuating, can’t hold set point | $180–$340 + thermostat or thermistor | Thermostat replacement, thermistor replacement, control board. Diagnosis confirms sensor vs. control board before ordering parts. |
Humidity control failure Humidity too low (cork drying), too high (mold risk) | $180–$320 + humidifier or sensor | Humidifier system repair, humidity sensor replacement, humidity controller. LA’s low ambient humidity (20–40% RH) requires active humidification in most wine cellars — system failures are more consequential than in humid climates. |
Fan motor failure Evaporator or condenser fan not running | $200–$360 + fan motor | Evaporator fan or condenser fan motor replacement. Fan failure causes rapid temperature rise and compressor stress. Priority repair. |
Door seal / gasket failure Heat infiltration, cellar struggling to maintain temperature | $150–$280 + gasket | Door gasket replacement or repair. In LA dry climate, gaskets harden and crack faster than in humid regions. A failed door seal causes the cooling unit to run continuously — burning out the compressor over time. |
Lighting failure Cellar lights out, LED driver failure | $120–$240 + LED driver or fixture | LED driver, lighting circuit, specialty cellar lighting fixtures. Often straightforward. |
Sub-Zero / EuroCave / Liebherr LUXURY Integrated wine columns and premium cellar units | $320–$640+ + OEM parts (premium pricing) | Proprietary cooling systems, dual-zone precision controls, European-sourced OEM components. Sub-Zero wine columns are common in Bel Air and Brentwood custom cellars. |
Diagnostic fee Service call + full system assessment | $89 Applied to repair | Applied to labor total when you approve. Includes cooling unit, insulation, door seals, and ambient condition assessment. We check everything before recommending a repair. |
