Update on Fans vs. AC:
May's bill came out. There were two weeks of May we would have run the AC, but our electric bill was at winter month usage levels. This month that only saved us approx. $25 (we were not in this house in May of last year, so I'm making an educated estimate), but each window fan is only $35 so that's almost paid one of them off!
It's 87* right now and still really comfortable in the house. The fan I like finally came back in stock so I've got three arriving Monday and a return label ready for the cheap knockoff they sent instead. Crossing my fingers the good ones come on Monday, LOL.
