With 2 full months of 90-100 degree days, but nights in the 60's with low humidity I started running tests with box fans in windows at night on the second floor to really great results.
Bought the big 6500FCM Centric Air Whole house fan and have been really happy with it. It can blast clear the air in the house on high in a few minutes and is barely perceptible on low where it runs at night.
I need to work on a better mount as Im pinching the duct but it still flows tons of air.
Its great waking up in the morning to a chilly bedroom filled with fresh country air for far less than even my super efficient 21 seer variable speed unit.
