Service
Sub-Zero wine fridge & cooler repair across the SF Bay Area — temperature, humidity, dual-zone & sealed-system faults fixed right. Call (650) 668-1554.
A wine refrigerator does something an ordinary fridge never has to: hold a precise temperature and a stable humidity, quietly, for years, so a serious collection ages the way it should. When a Sub-Zero wine unit drifts warm, swings between zones, or starts sweating inside, the bottles you have been cellaring are the first thing at risk.
We are experienced with Sub-Zero wine storage across the full range, from undercounter units to integrated columns and dual-zone designs. We diagnose why a unit has lost its temperature or humidity control and restore it to the conditions your collection depends on, with care taken around the cabinetry and the bottles inside.
We work on the full range of Sub-Zero wine storage, including built-in and integrated wine columns, undercounter wine coolers, and dual-zone units that hold reds and whites at separate temperatures. We are also experienced with wine and beverage units from other premium brands found in Bay Area kitchens and cellars.
These units combine sensitive temperature and humidity control with sealed refrigeration and electronic boards, so they reward a technician who understands how the whole system is meant to behave, not just how to swap a part.
The issues we see most are a unit that no longer reaches its set temperature, one zone of a dual-zone unit running warm while the other is fine, excessive interior condensation or humidity, frost forming on the back wall, and control panels that throw errors or stop responding.
These can stem from a failing compressor or fan, a refrigerant leak or sealed-system fault, a faulty thermostat or temperature sensor, a worn door gasket letting warm air in, or a failed control board. Because a wine unit is judged on consistency, even small drifts are worth diagnosing early.
A wine unit repair is as much about the contents as the appliance. We work to keep the cabinet closed and the temperature stable wherever possible, and we advise on protecting bottles if a unit must be powered down for sealed-system or compressor work.
Our goal is to restore steady temperature and humidity quickly, so your wine spends as little time as possible outside its ideal range. We explain what failed, what the repair involves, and how to keep the unit running well afterward.
Common parts are carried on the truck, with less common components ordered promptly so we can return and complete the work. We use factory-grade parts suited to your specific model to preserve the precise control these units are built for.
We serve the entire San Francisco Bay Area from our base in Los Gatos. Book online through our calendar or call (650) 668-1554 to arrange a visit.
FAQ
It can be, because steady temperature is what protects your collection. The cause may be a failing fan or compressor, a refrigerant or sealed-system issue, a faulty sensor, or a worn door gasket. We diagnose the specific failure so the fix actually restores stable cooling.
Independent zones have their own controls and airflow paths, so a single-zone problem often points to that zone's sensor, fan, damper or control circuit rather than the whole refrigeration system. We isolate the affected zone during diagnosis.
Some humidity is intended in a wine unit, but excessive condensation or frost usually signals a door seal, defrost, or temperature-control issue. It is worth addressing before it affects labels, corks or the unit itself.
Yes. We service the full range of Sub-Zero wine storage, including undercounter coolers, built-in and integrated columns, and dual-zone units, as well as comparable units from other premium brands.
No. We are an independent service company experienced with Sub-Zero equipment. We are not a manufacturer-authorized or factory-certified service center and are not affiliated with Sub-Zero.
Reviews
“The Viking refrigerator column in our Los Altos kitchen drifted warm and the alarm kept beeping. Mike found the condenser coils packed with dust and a weak compressor relay, cleaned the coils and swapped the relay. Temps are rock solid now and he was meticulous about not marking the panels.”

“The front element on our KitchenAid electric cooktop in Walnut Creek wouldn't heat past low. Jim found a faulty infinite switch and replaced it, but had to come back with a matching knob assembly the switch had damaged. Fair price and good communication between visits.”

“Our Sub-Zero wine column in Palo Alto kept drifting warm on the lower zone and the reds were getting too soft. Mike traced it to a failed evaporator fan and a clogged drain line, replaced the fan, and the dual-zone temps have held rock steady since. He was punctual and laid down a blanket so nothing touched the cabinetry.”

“The Thermador dishwasher in our Burlingame kitchen wouldn't latch and kept reporting a leak fault. Brian found the float switch was stuck and a worn door gasket, replaced the gasket and freed the float, then confirmed it ran dry. He explained the fault code so I understood what had tripped it.”

“Our Saratoga Sub-Zero refrigerator column was frosting over and the back vents kept clogging with ice. Tom diagnosed a sealed-system airflow issue and a stuck damper, fixed both, and walked me through how to keep the vents clear. No upsell, just the repair we needed.”

“The lower cavity of our KitchenAid built-in double wall oven in Menlo Park threw an F2 code and wouldn't hold temp. Steve replaced the oven sensor and a scorched relay, then ran a full calibration check before leaving. Tidy work and he was careful sliding the unit back into the cabinet.”
