How does a high ceiling help? Doesn't a high ceiling mean there's a larger volume of air in the room to cool? You'll also need a more powerful fan to move the extra air around.

- mr_overalls 5y agoA high ceiling _does_ mean that a modern A/C system has a larger volume of air to cool. And when people renovate high-ceiling houses, installing a "drop ceiling" is very common. But when fans and cross-ventilation are the primary means of cooling, high ceilings allow the hottest air in the room to accumulate, where it will not bother occupants (and thus forcing cooler air into the occupied space near the floor).
