Just before we had a new high efficiency air conditioning system installed to replace the old one, I bought a window unit for our bedroom.
I figured that way, as long as we had power, we'd at least have one room to hibernate in when the big system was down. Afte rall, you can't see the thing from the street since the master bedroom is on the back side of the house.
Well, we discovered something interesting.
We can turn the central unit off entirely before we go to bed, fire up the window unit, then close the bedroom door. The house stays cool enough throughout the night and morning to keep us from having to turn the central unit back on until after lunch.
This savings has been dramatic. I pass it on to you for your consideration.
