Placement of ceiling fans
We're buying a townhouse with no A/C, the climate here is temperate but it does get hot some summer days. It is a 2 level home and has clay tile roof which is a good insulator but I'd like to add ceiling fans to help move air and keep things cool and more efficient. We will probably have a portable A/C for the bedroom for those really hot days.
I dislike having air actually blowing on me while sleeping so I don't think I want one in the bedroom. Would it be useful/effective to have a fan in the hallway over the top of the stairs, to push air down in summer and pull up warm air in winter (we keep doors open)? Or is it necessary to have them in each room?
