Sub-Zero Wine Cooler repair and service in New York

Sub-Zero units are programmed to alert you before the temperature drifts critically. The icon often signals a dirty condenser or a minor sensor error. However, we recommend scheduling service promptly. Sub-Zero’s microprocessor log allows us to see exactly how long the temperature has been out of range, helping you assess if the provenance of your wine has been affected.

Sub-Zero uses UV-resistant, dual-pane glass with argon gas to insulate. If the seal between the panes fails or the door gasket is torn, condensation forms. This excess moisture can damage your bottle labels. We can replace the glass pack or the gaskets to restore the hermetic seal.

Yes. Evaporator leaks were a known issue in some older generations. We specialize in sealed system repairs for Sub-Zero wine units, replacing the evaporator with updated copper/aluminum components that resist corrosion, ensuring your unit holds a steady 55°F for decades to come.

Sub-Zero compressors are mounted on specialized rubber grommets to isolate vibration, which can disturb wine sediment and ruin the aging process. If you hear rattling or humming, these isolation mounts have likely hardened or cracked over time. We replace them to restore the vibration-free environment your wine requires.

Sub-Zero units are designed to maintain higher humidity (around 60%) to keep corks moist. However, visible mold indicates a clogged drain tube or a failing humidity sensor that is keeping the environment too wet. We clear the drainage system and calibrate the sensors to save your labels from rotting.
