Choosing the right window air conditioning unit for your room will help keep you cool and save energy when the weather heats up. Here are three important factors to consider when buying a new AC:

Turn off lights when you're not in the room or don't need them. This is one of the easiest ways to start saving. Turn off fans too, when you leave the room. Fans cool you, not the room. It costs almost $20 a year to leave one light on for 8 hours a day.
