It is important to purchase an air conditioning unit that is neither too large or too small for your home. A unit that is too large will waste energy and as well as money. It will also cool too quickly and not remove adequate humidity from the air. A unit that is too small will run constantly, thus wasting energy, without ever really cooling the home to the desired temperature. Find the total cubic living space of the home below.
Measurements given are for interior living space.
All ceilings are 8 feet high. Find total area of entire home and then multiply by height. As you can see from this exercise, there is a large amount of cubic living space in most homes that must be kept cool during the summer months. With so much living space to cool, the homeowner may wish to be more energy efficient. Protect windows, doors, fireplaces, and other vulnerable areas from infiltration of outside air.
