How to save with Window AC units

Now it Cooling season, now what?

Well when trying to save on your cooling costs and you have a window air conditioner, there is something you will want to know.
I often go into homes and see that the lower sash is raised for the unit to go in, and there is a space were the two sashes meet. When the windows are closed this is sealed, but not when the AC unit is installed. Remember that 1” gap along the width of the windows is open. Hand towels or tee shirts are what I use. If you have ever wondered what the short section of foam that comes with the window that you threw out last year, that’s what it’s for. Be sure that this gap is sealed. This lets the cool air out, or heat in. Either way it’s not efficient once you think about it. When you have more than one, the gap really adds up in losses, so fill the gap. It’s a great use for those old tee shirts too!
