I’m under the impression that ceiling fans in an air conditioned house in the summer will actually raise your cooling bill.
In all cases your taking hot air off the ceiling and mixing it with the cooler air below. Now instead of having 90 degree heat next to your 120 degree attic you are putting cooler air up there. This higher differential means that more heat is going to move from the attic to your living space.
So skip the fan and keep the heat on the ceiling where it belongs.
Also. I find that people obsess over the direction of their fan rotation but it makes almost no difference. “I’m pulling the cold air off the floor” they’ll say. Yeah right. Your circulating the air in the room resulting in a fairly even temperature. Direction doesn’t change the end result much. The only difference is if you want to feel the breeze.
