Window coverings are greatwhen they look nice but did you realize they can do more than look good? If you’re wanting to cut down on your heating and air conditioning bills one thing you can do is use your window coverings effectively. what I mean is make them work for you. Consider the material and thickness of your window coverings when choosing them. In the summer use a darker curtain or close the blinds completely to block the sunlight from coming in. We lowered the temperature of our home several degrees by doing this. In the winter leave your blinds or curtains open, so that the sunlight gets in and helps heat the house.
