The Ultimate Guide To Through The Wall Air Conditioners
Because we realize that not everyone is familiar with through the wall air conditioners, we wanted to do a little more than just review the best ones available. We wanted to put concrete information into the hands of our readers so they can not only purchase an air conditioner that will work for them but will be able to purchase the absolute best one for their home. A model that’s in their budget, provides great cooling and/or supplemental heating, and is easy for them to have installed. With those guidelines in mind, we’ve crafted this guide on the subject. The information contained in this guide should help all of our readers purchase a unit that will serve them for quite a long time to come.
Window Versus Through The Wall Air Conditioners
The first thing we’d like to discuss with our readers is the difference between window and through the wall air conditioners. And to be honest, there are very few differences between these models. They both can have the same cooling capacity and are roughly the same size, so they’re very similar to one another. However, although there are few differences between the two, the differences that do exist are exceptionally important. For instance, through the wall air conditioners require professional installation, if the consumer’s room doesn’t already have a hole through the wall for the unit. On the other hand, window air conditioners only require a window to operate.
Through the wall air conditioners are good for a room that doesn’t have a window, but that doesn’t mean that they can’t be used in rooms with windows. They may even be more energy efficient because these units have a tighter seal than window air conditioner units do. The problem with window units is that air can get out through the side panels of the air conditioner or the top. Through the wall AC units, however, that doesn’t happen because the seal is pretty tight. Other than those slight differences in use, however, window and through the wall air conditioners are quite similar to one another.
Purchasing A Through The Wall Air Conditioner
Now that we’ve discovered the main differences between window air conditioners, and through the wall air conditioners, let’s switch our attention to purchasing the best AC unit possible. The following features are some of the things that consumers are going to want to consider while they’re shopping for a new through the wall AC unit.
Choose The Correct Cooling Capacity
One of the first considerations the consumer is faced with when buying a through the wall air conditioner is the unit’s cooling capacity. The consumer wants to purchase a unit that’s large enough to cool the room it’s going to be installed in, but not so large that it wastes money. The consumer can determine the air conditioner’s cooling capacity by checking out the unit’s BTU rating.
The BTU rating tells the consumer just how much cooling (or heating for heaters) a unit will provide. The higher the BTUs a unit has, the more cooling (or heating) capacity it has. The consumer can then compare the BTU rating of the air conditioner with their room’s size to see if it will do the job. Below are some common air conditioner BTU ratings alongside the room sizes they are capable of cooling.
- 5,000 BTU: 100 to 150 Square Feet
- 6,000 BTU: 150 to 250 Square Feet
- 8,000 BTU: 300 to 350 Square Feet
- 10,000 BTU: 400 to 450 Square Feet
- 12,000 BTU: 450 to 550 Square Feet
Other Features To Consider
With the cooling capacity of the unit taken care of, the consumer is now going to want to think about some of the other features they need the unit to have. Although it’s impossible to thoroughly examine every single feature that can be found on modern through the wall air conditioners with a guide this size, we can cover some of the basics. Below are some of the features that consumers might want to consider before purchasing their unit.
- Supplemental Heating Mode
- Remote Control Operation
- Energy-Saving Mode

- Adjustable Louvres
- Auto Restart Feature

Through The Wall Air Conditioner Installation Requirements
Since we’re rapidly nearing the conclusion of this article, we need to address some final things the consumer needs to consider before purchasing a new through the wall air conditioner. These air conditioners can be installed in every home due to their particular installation needs. Since we don’t want any of our readers to purchase an air conditioner that they can’t use, we’ve included this section so consumers can make sure that their home is the right candidate for a through the wall air conditioner.
Consider The Wall
The consumer needs to make sure that they have a suitable wall for installing the air conditioner. The wall needs to be an exterior wall because the air conditioner needs to be able to vent to the outside. This wall also needs to be free of any plumbing or electrical structures around where the hole is going to be cut. The thickness of the wall also needs to be taken into consideration to make sure that it’s the thickness for the air conditioner’s depth measurement.
Consider The Electrical Requirements
The consumer should also make sure that their home supports the electrical requirements of their air conditioners. Although most newer through the wall models use 110-120 volt plugs, some models need 220-volt plugs. The power cord of the unit also has to be long enough to reach from the air conditioner to the outlet, so the consumer should keep that in mind.
Most Units Don’t Come With Installation Sleeves
Although most of the air conditioners we’ve reviewed or have seen come with weather seals and installation hardware, none of them come with installation sleeves. That’s because just about every air conditioner manufacturer requires the consumer to purchase them separately. Even the best through the wall air conditioner will require the consumer to buy a sleeve, so everyone needs to keep that in mind.
Some Final Thoughts
If the consumer has any doubts about installing their new through the wall air conditioner, then they should consult an expert and have them professionally install the unit. The consumer should also carefully read the directions that came with their air conditioner to make sure that they install and use it properly. If all of this sounds a bit overwhelming and the consumer wants an air conditioner that’s easier to install, then they might want to consider purchasing a window or portable air conditioner instead.
