Best Through-the-Wall Air Conditioners (Sep. 2026) - Rated by CherryPicks' Experts

How to Pick Through-the-Wall Air Conditioners

Benefits of a through-the-wall air conditioner?

• They are much more affordable compared to other air conditioners. This affordability is one benefit that makes them unique. However, the price range tends to vary depending on the different features and size.
• They fit tightly into the wall because of the wall sleeves, and this prevents drafts from entering when the air conditioner is on.
• It does not take up any window space, so the window is still usable. This can be very important, especially when the room has only one window.
• They have a better visual appeal. The aesthetics of the through-the-wall air conditioner is another benefit that makes it stand out.

How to choose a through-the-wall air conditioner

There are many things to be considered when you go shopping for your new through-the-wall air conditioner. If you want to buy your first through-the-wall conditioner or you want to replace an old one, there are some factors that you should pay attention to:

The thickness of the Wall

Through-the-wall air conditioners are installed by placing them into a sleeve that is in turn fitted into a hole in the wall. The thickness of the sleeve must be equal to or larger than the thickness of the wall so that the air conditioner fits properly. They must be installed on an exterior wall because they have to be vented.

Size of the room

The size of the through-the-wall air conditioner to be purchased is mainly determined by the size of the room in which it is going to be used. If the air conditioner is small, it will not properly cool the room to the required temperature. Getting one that is too big is not energy efficient and will cost more to operate.

Energy Efficiency

Air conditioners consume energy before they can produce cooling power. The Energy Efficiency Ratio (EER) is measured by dividing the energy consumed by the cooling power. Energy Star-rated units are even more energy-efficient, consuming 15–30% less electricity than standard models.

Sleeve Types

A through-the-wall air conditioner has sleeves that can either be a slide-out chassis sleeve or a standard through-the-wall sleeve. The slide-out chassis is built into the air conditioner itself and can serve units that vent out at the sides and back.

Noise level

Through-the-wall air conditioners are almost as noisy as window air conditioners because they have a dual design. They are made up of an air compressor that produces cool air and an air handler that uses a fan to blow the air into the room. But there are some models that have quiet operation features, but they tend to produce less cool air.

Dual installation options

There are some models of window air conditioners that can be installed both on windows and on walls. They are more versatile than regular window units and usually have a slide-out chassis. Models that vent only from the back are ideal for use through the wall, as opposed to those that vent from the sides.

FAQs

Are through-the-wall air conditioners the same as wall air conditioners?

Both types of air conditioning systems operate on the same mechanism. The only major difference is that the window air conditioner is mounted on windows, while the through-the-wall air conditioner is put into a hole in the wall.

How much power does a through-the-wall air conditioner consume?

Generally, a through-the-wall air conditioner can be plugged into a 115-volt power socket. But larger models need more power, and so they might need to be plugged into a 220-volt socket.

Are through-the-wall air conditioners noisy?

Generally, through-the-wall air conditioners are quiet, and as a result, they are used in bedrooms, hotel rooms, and so on. For these kinds of applications, it is important that the noise level be kept low.

Having to buy a through-the-wall air conditioner is a decision that has to be weighed based on your specific need. Your need is the most important factor when choosing a through-the-wall air conditioner. You should always choose one that will serve your needs. So, with this guide, you should be able to end up with the most fitting through-the-wall air conditioner that best fits you.
