Cellar Cooling Calculator
Measure your cellar. We match it against the capacity each manufacturer publishes, then build a cart you can buy, print, or scan.
How we size it
We match equipment against the cellar capacity each manufacturer publishes, taken from the product's own spec table. The heat-load estimate plays no part in that choice.
Room volume is length times width times height. We then add margin before matching, because a published capacity assumes a sealed, insulated room: a glass wall adds 35%, a missing vapor barrier 15%, an exhaust room above 85°F another 15%, and an uninsulated door 10%. Those margins are ours.
The BTU figure is there for orientation. It is not a contractor-grade load calculation, and WhisperKOOL's own documentation says glass, stone and concrete all change what a room really needs.
Undersizing shortens a system's life. Call 866-430-2877 before ordering if the room is commercial, has glass walls, needs more than one unit, or vents somewhere that runs hot.
