Gosh In southern Louisiana we have the awful heat plus humidity. This past week the temps have been hovering around 97-99 with heat index in the 100's. Our central AC unit doesnt get turned off at all. Since we have a lot of power outages, we also have a window unit in the den..if power goes off, we turn the generator on and stay in the den.We are buying another generator soon so that when power goes off, we can also run the central unit on 1 generator and use the other for TV, refrigerator etc. During hurricane Katrina, we stayed in the den for 8 miserable days! I'm praying for an early winter!
