How many BTUs do you need to cool a room of 435 square feet?

To effectively cool a room, it is necessary to have an air conditioner with the correct capacity. To cool a 435-square-foot room, a 10,000-BTU air conditioner is needed.

Many people believe that an air conditioner that is too large for the intended amount of space provides better cooling, but this is not true. An oversized air conditioner wastes electricity, and it does not cool as effectively as a unit of the correct size. An air conditioner that is too large lowers the temperature in the room, but it does not remove as much humidity as a unit of the appropriate size.
