What are Wall Mounted Air Conditioners?

A Wall Mounted Air Conditioner is an AC unit that is installed into the wall of a home. One side of the unit is exposed to the outdoor air, while one is exposed to the interior room. If installed properly, this device will successfully release cool air into your home.

Benefits of a Wall Mounted Air Conditioner

There are many different types of air conditioners on the market today. As such, a normal buyer has to decide between a wall-mounted AC unit, a window AC unit, a portable AC unit, a central AC unit, and a split system ac unit. That’s why it’s helpful to know the benefits of a wall-mounted air conditioner in comparison to its competition.

What to look for in a Wall Mounted Air Conditioner

There are many things to consider when looking for an AC unit. Below, we have covered some of the most important items to look for before buying including room coverage, size, voltage, efficiency, and warranty. 

Room Coverage

The first step in looking for a wall mounted air conditioner is to determine the size of space that needs to be cooled. In order to figure this out, you need to calculate the square footage of the room by multiplying the length times the width. Most product descriptions will tell you how much square footage can be cooled by the wall mounted air conditioner.


Most wall AC units are around 15 inches tall, 20 inches deep, and 25 inches long. The actual size of the wall-mounted air conditioner is not as important as the size of the unit’s wall sleeve. The wall sleeve is the connection between the outside air and the AC unit itself. Luckily, the majority of wall mounted AC units have the same size sleeve. This means that multiple different units will fit in the same location.


The majority of electrical outlets in the US are around 115 to 125V. Be sure to check the voltage of the unit. If the wall mounted air conditioner that you are considering is within this voltage limit, then you can just plug it in. In the case that your unit requires higher voltage, you will need to pay an electrician to install a higher voltage outlet in the location of your AC unit.


Another important thing to consider when looking for an air conditioning unit is its efficiency rating. An AC unit with high efficiency will actually save your money in the long run. One-way to measure the unit’s energy efficiency is to examine its EER rating (Energy efficiency). The EER is determined by dividing the BTU by the amount of energy needed per hour of operation. The higher the EER the better.


Luckily, part of the reason we selected the Pioneer, Senville, and Koldfront as the best wall mounted air conditioners due to their performance, price, and reliability. However, you never can be too safe. That’s why it is important to look for warranties before purchasing these devices. Many AC units offer a 1-year warranty. Be sure to read the list of what is covered by warranty before purchase.

Frequently Asked Questions

Are wall air conditioners good?

Wall air conditioners are good for cooling off one room in your home. These AC units will not cool your entire home, but can effectively cool smaller areas.

What is the difference between a through the wall and window air conditioner?

A through the wall air conditioner is mounted on the wall in your home and uses a connection sleeve to access the outside air. A window air conditioner is placed in a window and is connected to the outside air through the window opening.

Final Thoughts

Wall-mounted AC units can be a very effective and affordable method of cooling your home. However, it’s important to make sure that you are purchasing the right air conditioner for your needs. Be sure to weigh the pros and cons of wall-mounted air conditioners vs. window AC units and central AC systems before making a decision.
