If your bedroom door is closed, then open it slightly. That should allow
the air from the a/c to exit without causing overpressurization of the
bedroom space which would affect the ceiling fan. If that doesnt do the
trick, then, try making the ceiling fan go in the reverse direction to
see if that solves it. If that doesnt work, then, close the supply
registers by one-half. If that doesnt work ,then, dont use the fan
during the a/c season.
