What Is A Through The Wall Air Conditioner?

A through the wall air conditioner is an air conditioner that is installed on the side of a building or room, so that one side is exposed to the room and the other side is exposed to the exterior space. Also known as a wall mounted AC, wall AC, or wall sleeve AC, these air conditioners help to cool down the room by acting as a reverse heat pump, just like any other air conditioner.

Wall air conditioners are fairly similar to window air conditioners, although there are some differences. The biggest difference is that with wall units, the air is exhausted only out the backside of the unit, while with window units, the air is exhausted in both the back and the sides.

Therefore, you cannot install a window unit into a wall as the sides will be blocked and it will not work properly. However, you can install a wall unit in your window.

 

Things To Look For In A Quiet Through The Wall Air Conditioner

There are a few things you should be looking out for in your wall air conditioner to ensure you get the right one for your home and the one that is going to fit in with your lifestyle.

Noise Level

Of course, if you’re looking for a quiet air conditioner, the noise level that it operates at is going to be one of the first features you look at! Generally, AC units with lower BTU (British Thermal Units) capacity emit fewer sounds compared to those with higher BTU capacities. Most wall air conditioners create between 50 and 60 dB of sound, but quieter ones will operate at a noise level of less than 50 dB.

British Thermal Units (BTU)

BTU is the amount of thermal energy (heat) required to raise the temperature of 1 lb of water by 1 degree Fahrenheit. You generally need an AC with about 20 BTUs of cooling for every square feet, so homes that house more than two people will need around 600 BTU for each additional person. A kitchen will need more BTU, while sunny/shady spots will also have varying BTU needs. Therefore, you need to take into consideration the size of your room and the position of it, plus it’s use, before deciding how many BTUs you will need.

Room Size

You should take into consideration the size of the room you are trying to cool with your air conditioner. If your room is too big for the unit, then you won’t feel the benefits, whereas if it is too small, you may get too chilly! Around 5,000 to 8,000 BTU is enough to cool a small space, while between 10,000 to 12,000 BTU is great for medium to large areas. Anything higher than 13,000 BTU is strong enough for large commercial spaces.

Adjustability and Settings

Many air conditioners come with adjustable settings so you can customize the airflow and temperature in your room. This can be great for ensuring a quiet unit, because if you are finding it too loud, you can adjust it to a lower setting.

Some units also have built-in dehumidifies. Dehumidifiers help to get rid of any excess moisture so your house is prevented from mold.

Efficiency

Having an air conditioner on all the time can use up a lot of energy, so purchasing an energy saving wall air conditioner can be a great way to be efficient. This way, you’ll also feel less guilty about having it on all the time!

If you’re ready to find the best quiet through the wall air conditioner for your home, take a look at the quietest air conditioners we recommend below. These are all available to you on Amazon.
