Even when I give in and turn the AC on in order to sleep I find 80 about right. If I kick it down to 78 I end up pulling up a cover sometime during the night. As Al says, the most important thing is sucking out the moisture. All three of my units have an "economy" mode which helps them kick in and out instead of running constantly.
Yesterday and breeze once again died and I have AC going in the front bedroom and great room. I dread getting my bill.

When you folks are notint costs are you listing it in BZ or US $?
