No products found.

Considering how unpredictable climate change is, the seasons are becoming harsher than ever. Summers are a lot hotter and ridiculously uncomfortable even when you are indoors. Every household needs to have a working air conditioner and not just that, but the best model possible.

There are different types of AC in the market, and they have varying capabilities. These capabilities depend on several factors, such as size, speed, build, and overall performance. In this guide, we will be looking at through the wall air conditioners.

This is a specific type of ACs that you place through the wall, much like the name suggests. They are not that different from window ACs, but we’ll get to that in a bit. In-wall or through the wall air conditioners belong to the category of room ACs and are fit into a hole created in your wall. They suck heat from the room to cool and release.

Like other room ACs, this type is designed to serve the needs of a single room but not several rooms at once. That capability belongs to a central air conditioning unit.

Differences Between Window Air Conditioner and Through the Wall Air Conditioner

While through-the-wall and window ACs are quite similar, they also have noticeable differences. These differences make the ACs suitable for different situations. 

1. Functionality

The most obvious difference is that one is designed for window installation and the other wall installation. Window ACs let out hot air from the back and sides while in-wall vent out heat specifically from the back

2. Space used 

Both units come in varying sizes depending on the size of the room and the power you need. In-wall units can fit into a custom hole anywhere on the wall. Window units are a lot easier to install, but they are not permanent. You’ll have to remove them at the end of the season.

3. Cost and performance

Through-the-wall units tend to be more expensive compared to window units. But you won’t have to worry about them once they are installed. They are also more energy-efficient than window units and will last longer.

The slide-out chassis is designed to vent heat out from the sides as well as the rear. It is an excellent wall sleeve for both through-the-wall air conditioning unit as well as window units.

The through-the-wall sleeve, however, is specially designed for in-wall AC units and vents out heat through the back. It is, overall, the best option.

What Are the Benefits of Through the Wall Air Conditioners?

You probably have various personal reasons why a through the wall unit makes more sense for you. Still, here are some benefits of getting through the wall air conditioners for your room. Hopefully, they will aid in your decision to buy one of these wall AC units.

1. Convenience

In-wall ACs can be turned off in rooms you don’t intend to use. This is convenient and has an energy saver mode. Also, air conditioners are only necessary for a small part of the year. In-wall AC units will save you the trouble of mounting and unmounting the AC every time you need it.

2. Overall cost

Through the wall, air conditioners usually cost a lot more than its cheaper alternative. However, when you factor in its energy-saving and long-lasting capabilities, it becomes a more affordable option. Additionally, you won’t have to worry about the cost of installing and uninstalling it as it offers a permanent solution.

3. They save space

Considering the in-wall unit is placed into the wall, there is a lot more space saved. You will barely notice the unit as it tends to fit snuggly into the wall. Space might not be an issue for big rooms, but for small rooms and compact office spaces, you want an air conditioner that won’t make that won’t make the place feel cramped.

4. Aesthetic appeal

Some AC units are bulky and may change the appearance of your room. If you mind cumbersome appearance and would rather keep the aesthetic feel of your décor, the through the wall air conditioner is your best option. It will be easily tucked away and remain out of sight. The latest versions of these units can give your room a contemporary and elegant look.
