I keep all my windows open all night long, then I close the ones facing the sun during the day, and I run every fan in the house I can
 
Makes a big difference ...
 
And when I can't stands the heat no more, I turns on the AC and burn the power baby !!!
 
Only takes an hour or 2 to cool our whole house down with our 2 units 
 
There, is that what you wanted to hear ? 
 
I only thought the OP wanted options other than AC
