You might try doing a search on this. There have been quite a few discussions about it recently.
It seems that the overwhelming opinion is that there is just too much humidity in FL for it to work. It works best in a "dry heat" like you would find out west. I think someone said that about the best it would do in FL was maybe blow air up to about 3 degrees cooler, which at 95 degrees just isn't going to make a difference!
