I've seen floor fans, ceiling fans, wall fans, and air conditioners, but so far I haven't seen any window fans. When I was growing up in the U.S. south (before air conditioning), we had window fans that drew outside air into the house through open windows in other rooms. Has anyone tried that approach to whole house cooling and, if so, where could I find such a fan? Thanks. I searched the forums so please don't fuss at me if this has been asked before!
