How the Wall Unit Differs From The Window Unit
These two types of air conditioners may look the same, yet they have a big difference. You will notice that the vents of the wall unit are located at the back, while the window unit has the vents at the sides. The wall AC unit is designed with a compact chassis that can be fitted into openings in the wall, and it would be hard to take the unit out so it will have to stay there permanently. Unlike window units, the back of the wall units hangs minimally at the exterior walls or they can even sit flush in there.
Thru the wall air conditioners work by taking the hot air into its condenser and when it’s cooled, it blows the air back into the room. As the motor runs, it produces heat, and the hot air in the device is tunneled through the vents at the back so that the room stays cool.

A Wall mounted air conditioner is a good option if central air conditioning systems are too expensive for you. However, you can only cool one room with this device even if you buy a large capacity because the vents are limited to blow only in the area where the unit is installed. This may be its limitation but it will still save you from paying a whole lot of excess in utility bills. Keep in mind, if you are using only one room, you will be wasting cooling costs when the living room is not in use and you are in the kitchen or in the bedroom.
You can find many brands like Frigidaire, LG, Sharp, Fedders, and more at Amazon.com being offered at discounted prices.
Tips On Choosing Your Air Conditioner
Not all air conditioners can effectively work in all types of areas because of different room sizes, and you need the proper corresponding cooling capacity from your air conditioner to fit the room.
To compute the area: Length x Width in square feet=Total area to be cooled. You can refer to the chart below to get the equivalent BTUs needed.
| To cool an area of: | Get the air conditioner of this size: |
| 100 to 150 square feet | 5,000 BTUs |
| 150 to 250 square feet | 6,000 BTUs |
| 250 to 300 square feet | 7,000 BTUs |
| 300 to 350 square feet | 8,000 BTUs |
| 350 to 400 square feet | 9,000 BTUs |
| 400 to 450 square feet | 10,000 BTUs |
| 450 to 550 square feet | 12,000 BTUs |
| 550 to 700 square feet | 14,000 BTUs |
| 700 to 1,000 square feet | 18,000 BTUs |
| 1,000 to 1 400 square feet | 24,000 BTUs |
Air conditioners are equipped with a thermostat that measures the room temperature. This reading will be used to cycle the compressor. Be careful that you do not purchase a system that doesnt have a high enough BTU capacity for the size of your room. This decision may be disastrous when buying thru the wall air conditioners. Since the unit will have less BTU’s than necessary, the room will never obtain coolness. As an outcome, the compressor will fail to cycle off.
Buy the right type of through the wall air conditioner by referring to the chart above.
