Cellar cooling
Room volume, insulation, glass area and the temperature next door decide the size. The model number is the answer, not the question.
Every unit rejects heat somewhere: a garage, a mechanical room, outside. Self-contained units need that space behind the wall; split systems move it.
A through-wall unit next to a dining room will be heard. Ducted and split systems put the compressor where nobody is sitting.
Review the room’s humidity conditions alongside cooling. Some systems offer humidity management; a separate humidifier may be appropriate for other rooms. Confirm the selected equipment’s capabilities before ordering.
Cooling belongs in the cellar design from the start. Wine Hardware’s selection includes WhisperKOOL, Wine Guardian, CellarPro and CellarCool, with through-wall, split, ceiling-mount and ducted arrangements. The right layout depends on more than a room-volume label: the equipment position, exhaust route and service access all need a place in the plan.
Bring room measurements, construction details and photos to our Walnut Creek team. Compare the specific models and their included controls, then confirm installation materials and freight before ordering. Ask about fit at Wine Hardware.
Compare the CellarCool CX2200, CX3300 and CX4400 for a through-wall cooling arrangement. These units combine digital controls, dynamic airflow and flexible mounting brackets. Their published capacities and dimensions differ, so an existing wall opening is useful information to bring into the selection conversation.
Tell Wine Hardware which unit you are replacing or send a plan of the new cellar. Confirm the room load, wall opening, exhaust space and drainage before ordering. Our Walnut Creek team can help identify the model and discuss delivery and installation expectations. Ask about fit at Wine Hardware.
Straightforward through-wall cooling at the sensible end of the price list. The CX2200, CX3300 and CX4400 are rated for cellars up to 300, 650 and 1,000 cubic feet. When the room is small, well insulated and the budget matters, this is where we start.


Start with the cabinet and its surroundings when comparing CellarPro cooling. The 1800QT and 1800XT in this selection are indoor units with digital controls, adjustable humidity control and a choice of top or rear hot exhaust. Their output and intended applications differ, especially when the equipment sits near living space or faces warmer conditions.
Send the cabinet or cellar details to Wine Hardware, including the existing unit if this is a replacement. Confirm airflow, electrical requirements and any separate duct or cold-weather options before arranging delivery. Ask about fit at Wine Hardware.
Compact, hard-working through-wall units for closets, under-stair cellars and large wine cabinets. The 1800XT is rated for cellars up to 250 cubic feet; the 1800QT is the version built for cabinets near living areas.


Every cooling unit in the catalog in one list, across WhisperKOOL, Wine Guardian, CellarPro and CellarCool. Sizing is the whole game. Send us the room before you pick one.
