You keep your house set to 72 degrees F? Holy crap! No wonder your electrical bill is so high in the summer. Here in Toronto our summers are not as hot (low to mid 80s on peak season) but they are quite humid. I keep my thermostat set to 79 just to pull the moisture out of the air and it's quite comfortable.
