- What type of window space can I install a unit in?
- Is an in-wall or slide-out unit possible?
- How many BTUs do I need to effectively cool the room?
- Will it need to be portable?
You may also need to factor in the ease of installation and the energy efficiency the AC unit offers.
Types of air conditioners vary depending upon the window space available. A vertical hung sash window that opens up and down typically can accommodate a standard window air conditioner, while a slider/casement style AC unit is needed for casement windows that crank open or slide open horizontally. These types of indoor air conditioners sit on the window sill with the window partially open, held secure in place by the window sash and/or other manufacturer recommended methods.
In-Wall or Slide-Out Window AC Units
The chassis is the supportive frame for a window air conditioner unit. Units built with a slide-out chassis can be removed and may be installed through a wall inside an air conditioner sleeve (which may require brackets for support.) Certain in-wall AC units can be installed so they sit flush with the wall, creating a sleek, minimalistic look. In-wall and slide-out chassis air conditioner units don’t have the same side-vents a regular window air conditioner has, but they do offer a high cooling capacity ideal for bedrooms and offices.
Note: The thickness of your wall will determine if installing an in-wall air conditioner is possible.
BTUs, or British thermal units, are units of energy. Cooling is measured in BTU per hour. According to Energy.gov, “Based on size alone, an air conditioner generally needs 20 BTU for each square foot of living space.” On average, most window AC units or portable air conditioners range from 5,500 BTU per hour to 14,000 BTU per hour. You may also see units with a cooling capacity size of a ton. A ton, in air conditioner cooling terms, means that unit has a rate of 12,000 BTU per hour.
While the size of the room is key in figuring how much BTU is needed, don’t forget to consider how much sun or shade the room receives, the effectiveness of the room’s insulation and the height of the ceilings — it takes more energy to cool a room with 9-foot or higher ceilings.
Tip: When buying a window air conditioner, avoid one that is oversized (too high BTU) for the space. Use a BTU calculator to figure the right size for the space.
Portable AC Units
A portable AC unit is an ideal choice if your room has only one window or a window AC unit isn’t permitted by your landlord. Consider a portable air conditioner for rooms that need supplemental cooling, such as offices, enclosed porches or loft rooms. You can find units with timers, multi-fan settings and that are easy to move from room to room as needed.
