Choosing the Right Window Air Conditioner for Your Apartment

Bigger isn’t always better, at least when choosing a window air conditioner is concerned.    Why?  An air conditioner serves two functions – the primary is cooling a room.  The second, and also important function, is to dehumidify the room.  An air conditioner too large for your apartment will cool it to your desired temperature, but will shut off before the room can be properly dehumidified.  This poses an issue, because a room not properly dehumidified will still feel “sticky” and uncomfortable.  Choosing an air conditioner with the proper BTU rating (cooling capacity) for the size of room you are trying to cool properly dehumidifies the room, and also save electricity.  Energy Star™  offers the recommendations below.

Capacity Needed (BTUs per hour)

100 up to 150

250 up to 300

7,000

300 up to 350

8,000

350 up to 400

21,000

1,200 up to 1,400

23,000

1,400 up to 1,500

24,000

1,500 up to 2,000

  1. Also, make the following adjustments if any of the following apply to you or the room you are cooling:
    • If the room is heavily shaded, reduce capacity by 10 percent.
    • If the room is very sunny, increase capacity by 10 percent.
    • If more than two people regularly occupy the room, add 600 BTUs for each additional person.
    • If the unit is used in a kitchen, increase capacity by 4,000 BTUs.
    • Consider where you install the unit. If you are mounting an air conditioner near the corner of a room, look for a unit that can send the airflow in the right direction.

  1. This is good information! I wouldn’t have any idea how to even start looking for an appropriate AC for the space.
