Sizing of an air conditioner. When choosing the size of your AC, keep in mind your room size and the number of people in the room. Also, think about the number of things kept in the room. These three factors are the main determinants of air in the room that will need to be cooled. Every object in the room will need to be cooled. So the less things you have, the less you’ll have to spend on your electricity bill. Once you know your room size, think about measuring cooling capacity (BTU). The room cooling won’t be cost effective or cool effective if the BTU/hour is right.
