I live in middle Georgia now and have not used A/C for 5 years. People think they need it because they use it constantly and are not acclimated to the hotter temps. Though grant it if the temp drops below 70 I am reaching for a sweater.
I did get a portable a/c unit for the new house mainly because I have 14 year old dogs and worry excessive heat triggering heart problems though the new house is much better insulated, has shutters and a whole house fan so it should be MUCH cooler than the house I am in now.
