My living in the deep south where temperatures get into the high 90's and as high as 115 degrees not counting the heat index during the summer all my ceiling fans run 24/7 all year long and air conditioner is set to 75 during summer months.
We don't have four seasons here like some other places and what little of winter we have which is usually from end of November to end of January I still run the ceiling fans and will not have air conditioner on.
It takes care of itself with ceiling fans in every room of the house during cooler weather and for us that is getting down into the 80's or lower.
