Re: open door cools faster
Could be the orientation and layout of the house, could be the window screens, could be any number of things. Our house has absolutely zero air flow, doors open or not. We use 30" box fans in several windows to draw air into and push air out of the house. I have found that it's best to draw air into the house which "pressurizes" the house and forces the hot air out. This way the rooms (primarily bedrooms ) get cooled first.
