If you are considering a new wine cellar cooling system or a replacement system, the following provides a brief overview of the three systems widely used for wine cellars.


Stand-alone cooling units are perfect for wine cabinets and some wine rooms. Self contained units are mounted between the studs of an existing wall. One end of the system blows cool air in to the cellar and the other end absorbs heat from the cellar and exhausts the heat into an area adjacent to the cellar.


Ducted cooling units offer additional flexibility for configuring your wine cooling system. A ducted unit has more installation options than a self-contained unit. The unit may be installed up to 25 ducted feet from the cellar with the cool air flowing to the cellar and the heat exhaust ducted to the outside of the home.


Considered the most efficient way to cool a cellar, Split system cooling units have separate condensing units and fan coils. The cooling unit condensers require significant space for ventilation. In most cases the cellar location does not include an area for these functions. By splitting the cooling system, the condenser can be placed in a space better suited for heat and noise dissipation while the quiet evaporator is inside, or near, the cellar.

Ductless Split Systems: The evaporator is inside the cellar while the condenser is in another room or outdoors. They are connected via 2 copper lines.

Ducted Split System: The evaporator is in another location indoors and the condenser is either indoors or outdoors. They are connected with ductwork which allows the cool air to flow into the wine cellar through a vent, usually in the ceiling, and carries the warm air out via a return air duct.
