Hi all,

I will open all the upstairs windows and turn on the cheap floor fan that
the PO's left for me to try to blow some outside air through the house.
It doesn't seem to be working - outside temp will drop to 65 degrees or
cooler overnight but the bedroom will still be 75 degrees or so when I
wake up in the morning. I suspect if I could get the ambient temp. of the
upstairs down to the same temp as the outside and then shut everything up
when I left for work, it wouldn't even be as hot when I got home, but I
seem to be getting little or no cooling from having the windows open.

You have to move the hot air out and the cooler air in. A good powerful
window fan can do wonders. You have the fan blowing out of the bedroom and
only open the windows in the rooms to be used. You can suck air a long
distance through the house that way and cool everything along the way.

Ceiling fans just circulate the hot air already in the room, floor fans
don't do much better. You have to blow hot air out and draw cooler air in.
You may even want to consider a whole house fan that blows up through the
attic and out the eaves. That also gets rid of the blanket of heat above
you.

OTOH, I bought my first AC for our bedroom back about 1968 and have not been
without at least a cool bedroom since. You can get them for $99 these days
and on a hot humid night, nothing beat real AC.
