WhisperKOOL Split System is often the most efficient way to cool a cellar. Wine Cooling Unit condensers are typically noisy and require significant space for ventilation. In most cases, the wine cellar location does not include an area for these functions.

A licensed HVAC/R technician is required for the installation.
