Depending on the size of the room that you are trying to cool off, you may need more than one window air conditioner in your household. For bedrooms and standard sized rooms, this is typically not a problem. Of course, it is still important to make sure that you are getting the correct size of air conditioner in order to properly cool down the room and not have the air conditioner working too hard.

For homes that have an extremely large living room or an open floor plan for the living room, kitchen and dining room, more than one window unit may be needed. What you will want to do is to measure the square footage of the area.

Even though you may not be able to get an air conditioner for that particular square footage, you can get a couple of smaller ones that when added together can handle that large of a space. You will simply have to put a little thought into it.

As you start to figure everything out, you may find that not each air conditioner has to be of the same size. If every single window ends up with an air conditioner unit in it, it may be time to think about upgrading into a central air unit.

Not only will the central air unit provide the right amount of cool air for you in your room, but also it will have a much nicer look than ten air conditioners hanging out of your windows.
