Hubby Tony and I have decided we like having the bedroom windows open overnight. The outside sounds are soothing to fall asleep to, and the chirping birds are invigorating when I wake up.
When we lived in our big house, opening and closing up the house was a big deal. The family room, kitchen, and master bedroom each had multiple-window bays. All of the other rooms except for the smallest bedroom had two individual windows. Consequently, once the air conditioner went on it tended to stay on.
Our apartment-style condo only has six windows. It only takes a couple of
minutes to open or close all of them, so Tony and I decided that until the
weather gets oppressively hot and humid we'll have the best of both worlds.
When the temperature inside the house exceeds the air conditioner thermostat
setting, we close up and turn on the air conditioner. When the
outside temperature drops below the thermostat temperature setting, we open the
windows back up.
