How to Choose the Right Size Air Conditioner
Select the Right Room Air Conditioner.
Bigger isn’t always cooler. That’s especially true when you select a room air conditioner. Operating an air conditioning unit that is too large for a room wastes energy because it’s less effective at removing humidity from the air.
That’s why it’s important to select the right unit to fit your needs. Room air conditioner sizes are rated in BTUs (British Thermal Units) per hour. The chart below will help you choose a room air conditioner size that’s right for you.
Other factors to consider in properly sizing a room air conditioner
- If the room is very sunny, increase the size by 10%. If it is very shady, decrease the size by 10%.
- If more than two people regularly occupy the room, add 600 BTUs per hour for each additional person to the size selected.
- If your room air conditioner is intended for use in a kitchen, increase size by 4,000 BTUs per hour.
