WhisperKOOL Through-The-Wall Wine Cooling Units

Q: Can I install a WhisperKOOL through-the-wall unit myself?

You can install it yourself if the unit mounts into a properly sized interior wall with correct ventilation. Do not install it in an exterior wall or unconditioned space—it will fail to maintain temperature.

Q: What size wine cellar can a through-the-wall unit handle?

Through-the-wall units are designed for cellars up to about 2,000 cubic feet depending on the model. Do not undersize the unit—an undersized system will run constantly and fail to protect your wine.

Q: Can I use a through-the-wall unit in a glass or open wine cellar?

Do not use through-the-wall units in glass-enclosed or poorly insulated spaces. These systems require a sealed, insulated cellar or they will not maintain stable conditions.

Q: Do through-the-wall units require ventilation on the exhaust side?

Yes—these units must vent into a properly ventilated adjacent room to remove heat. Do not vent into a small enclosed space or closet, as heat buildup will reduce performance and damage the unit.

Q: Are through-the-wall wine cooling units quiet enough for living spaces?

They are quieter than older models but still produce audible fan and compressor noise inside the cellar. Do not use them if you need near-silent operation—choose a ducted or split system instead.
