Ahhhh, ac, my bff in the summer! I also have to consider my antique mahogany furniture, which tends to grow mold if it's not cool enough.
I found that out 1 summer when I thought I'd go w/out ac. WRONG move!
Mold cannot live in AZ ;) It FEARS AZ...you furniture would be drier, sure...but it would quickly petrify and thus last forever. We have a whole forest filled with the stuff!
