We've just moved into a 1938 brick colonial in the DC metro with a finished attic (but for the very top portion). The attic has flat narrow ceilings (about 4 ft wide) with the rest of the ceiling slopes on both sides along the roof with 4 ft high vertical walls at the bottom. In each of the attic's two finished rooms there is a ceiling fan mounted on the flat ceiling.

Today it is in the 80s outside, and the attic is in the 80s. My father is visiting, and I tried to cool his room down a bit today by turning on the ceiling fan. I can feel no air coming from the fan. Even standing close to the fan and with it turned on the highest setting with quickly rotating blades, I feel no air flow - hot, cool, or otherwise. Stuck a piece of tissue paper up there, and it didn't move. Some data points:

* the fan is rotating counter-clockwise as it is supposed to in hot weather
* individual fan blades are angled in the correct direction
* for fun, I rotated the fan clockwise and the air flow was identical

I am mystified as to why the ceiling fans would not produce air. There is a fan a level lower that works perfectly fine - rotating counter-clockwise, fan blades angled in the same direction - and even at a low speed, casts a nice breeze. Any help is much appreciated.
