Ductless HVAC Split-Systems have become so popular and they are projected for double-digit sales growth in the next decade1. A ductless split-system offers small equipment size, simple installation procedures, zoning capabilities, and clean air delivery.

Can this technology be used for wine cellars? Absolutely!

“There isn’t a day that goes by when we are not presented with a challenging configuration and a ductless split-system is the answer” says Fred Tregaskis, owner of Summit Wine Cellars, dba Summit Cool Cellars. It’s a perfect solution for small to medium sized wine rooms where a) there isn’t room for ductwork, or, b) no mechanical room for HVAC equipment.

Let’s take a look at the ductless split-systems for wine cellars offered by the two top manufacturers of climate control systems for wine cellars, Wine Guardian and WhisperKool.

Wine Guardian, a division of Air Innovations, has been making specialty climate control systems since 1986. Their ductless split-systems are comprised of surface mount or through-the-wall and ceiling mounted systems.

Ductless split-systems stand out for their versatility. Not having to install ductwork make this type of system a strong option for a wine cellars that are an addition to the home, or glass cellars/walls where the cooling system cannot be placed inside the cellar. These systems are easy to install by a single mechanic. For many applications, such as restaurants, the biggest advantage is the peace and quiet. The noisy part of a cooling unit, the condenser, is in another location.

HVAC contractors that have added ductless split-systems to their product line and service have a proven lucrative product offering. These systems are a great business opportunity with a positive impact to your bottom-line.
