Since
1977
Wine cellar cooling systems: it's where we started.
Reliable began in 1977 as a refrigeration company, and wine caves and cellars across the valley still run on systems we put in. Cellar climate is its own craft: temperature and humidity have to be right and stay right, season after season, without noise or drama. We design, install, and service wine cellar refrigeration systems sized to the room, the collection, and the way the space is built.
Since 1977
Our founding trade. The valley's caves and cellars have run on Reliable systems for decades.
Wine Cellar Humidity Control and Temperature
Both engineered together: cellar climate is more than a cold room.
Wine Cellar Cooling System Sized to the Space
The room, the insulation, the collection: designed for, not guessed at.
Quiet, Steady, Reliable
Climate you don't have to think about, which is the entire point.
A Wine Cellar Cooling Unit Is a Promise to Your Collection
Wine punishes climate mistakes slowly and permanently. A wine cellar cooling unit has to hold its numbers through heat waves, cold snaps, and power blips, and do it quietly, for years. That’s the standard we’ve built to since the beginning, from private cellars to full caves.
Wine Cellar Refrigeration Service, Including Systems We Didn't Install
Inherited a cellar system with the house? Bought a property with a cave nobody has documentation for? We’ll assess what’s there, tell you honestly what it needs, and keep it running, or design its replacement when the time comes. One note for clarity: we don’t offer 24-hour emergency refrigeration service.

Questions & Answers
Frequently
Asked Questions
Common questions about our services and process. If you don’t find what you’re looking for, call us at 707·252·7227.
How is wine cellar refrigeration different from a regular AC unit?
A cellar needs steady temperature and controlled humidity together, not just a cold room. Wine cellar systems are built for that, so they run quietly and hold the climate season after season.
What temperature and humidity should a wine cellar hold?
Most collections are kept at around 55°F with relative humidity between 55 and 75 percent. The right targets depend on your collection and the room, and we size the system for both.
Can you service or replace a wine cellar cooling unit someone else installed?
Yes. If you inherited a cellar system with the house, we assess it, recommend what it needs, and then maintain or replace it.
Do you offer emergency wine cellar refrigeration service?
We do not offer 24-hour emergency refrigeration service. Call 707-252-7227 Monday to Friday, 7 AM to 5 PM, and we will arrive on time and give one honest price.
Do you work on both home cellars and commercial wine caves?
Yes. We work from a collector’s closet conversion to winery production spaces and caves.
