I vote for fresh air over AC, but I am much more comfortable with higher temps and air motion , than simply keeping it cooler.
Course saying that, I apparently have allergies
, but I still have the windows open...Maybe this year I should have made the exception!
Anyway the turn on point is July 4th at the earliest for the most part. Cause no one can sleep thru the fireworks....When on it is set at 80 degrees, and we have fans on.. I just can't stand to pay for it any hotter, but I do leave the house and head for the pool as often as possible.
