I think central AC here is truly not necessary. We have one window AC unit for the living room, which has pretty much nekkid western exposure. That one window unit makes the whole house more manageable in this weather. It still got quite warm inside--85-ish--but it wasn't as awful as it would have been without the window AC in the living room. We've only had that for about four or five years. Most people here live without AC and most of the time, it isn't needed. But boy, when it is...whoof. 103 is definitely hot enough for me.
