There are several things to consider when selecting an air conditioner. First, you need to know the size of the room. If you multiply the length by the width, this will give you the square footage.
A/Cs are available in both 100 volt and 220 volt configurations. Air conditioners for a main floor vs. a second floor will be different. Since heat rises, upper floors will require a higher BTU air conditioner. You should also consider the room's conditions. Is your room normally sunny or shady? A sunny room will require a higher BTU, while a shady room will require a lower BTU. Ceiling height is also important-- anything higher than eight feet will require additional BTUs to cool the space. Lastly, the number of people in the room should be considered. A larger air conditioner will be needed for a larger amount of people.
