COOLING UNIT BUYING GUIDE
Wine Cellar Cooling Unit Installation Basics
Forced air through the wall systems are the most basic in terms of installation. Basically a hole is cut into the wall where the cooling unit is mounted leaving the front evaporator side in the cellar providing cool air while the condensing warm air side would reside in an adjacent room. Ideally that room where the warm air is venting into should be larger than the wine cellar and a non living space that does not exceed 80 degrees.
Self contained ducted systems can go through the wall as well, but have the flexibility to be located remotely in any room within 10-25 feet of the cellar. These units have adapter kits that accept ductwork on both the evaporator and condenser side so you can duct the cool air into the cellar as well as duct the warmer exhaust air somewhere else... even to the outside! They will make some noise so again, you want to avoid installing these units in a living space. Split Cooling Systems are the most complex in terms of installation as there are two separate components, the evaporator and the condenser. These two components need to be connected by refrigeration lines and also each will have separate power sources which may need to be hard wired. These installations require both a licensed HVAC technician as well as a qualified electrician.
