A small through-the-wall air conditioner is a unit installed into a building wall and can cover large areas depending on your ambient room conditions. They are especially suited for cooling living rooms, offices, bedrooms, or apartments.
There’re multiple reasons why anyone can opt for the smallest through-the-wall air conditioner. It could be that they reside in a small room and don’t want it freezing in there, or perhaps they only aim to cool a specific area. Whatever the case, your utmost desire is to stay cool during the humid summer months.
While staying relaxed and comfortable all summer long is presumably a god-given right especially for those who are lucky enough to live in rooms where opening the window will do a decent job, most of us still rely on good air conditioning to save the day. The smallest through-the-wall air conditioners provide you the relief you need to deal with temperatures that reach triple the digits.
Getting down to basics, here are the five smallest through-the-wall air conditioners that are relatively durable, equipped with up-to-date features, reliable, and offer the best cooling power.
Things to Consider When Choosing a Small Through the Wall Air Conditioner
Energy-efficiency is a useful feature as it determines the amount of power that your AC uses. An energy-efficient through-the-wall AC minimizes power loss, thus saving you the headache of paying more electric bills.
With an energy-efficient machine, be assured of a dependable unit and an opportunity to save more power. Furthermore, through-the-wall units are more energy-efficient than other types of AC. All you need to do is take your time to find the correct size to cool your room properly.
The room size is an important feature that determines the size of the AC to buy. A bigger room requires a bigger AC. For instance, a space of 450 sq. ft. requires an AC of around 12000 BTU for efficient cooling. Getting the correct room size will help you settle on an ideal unit that cools the room sufficiently.
Additionally, the AC size will vary depending on the ceiling height, the shape of the room, and the presence of any destruction. However, if you have a small space, choose a small AC like mini-split air conditioner.
The size of the unit is one of the fundamental factors to consider. It is designated in British Thermal Units (BTU). The size determines how powerful the machine can operate.
The thermal rating is generally used to show how much heat is required to raise one pound of water temperature by one degree. If you have a bigger room, you’ll go for higher BTU ratings and vice versa.
Different AC models come with various controls. The controls help you to set the unit according to your preference. Some even allow you to use the remote control from your comfort zone.
You can adjust the modes or temperature settings to an optimal level using the controls. However, you’ll find that the more the controls, the higher the price of each model. Anyway, you will get the value for your money based on the AC you choose.
The fact that the AC you choose can dehumidify the room is one of the best features to settle on. Besides, this feature helps save you more energy bills as these units often have Energy Star Rating.
The energy star rating reduces energy loss while enabling the AC to run at a higher temperature. The feature also helps to remove excess moisture from the room while maintaining a calm environment.
The displays are good since you can easily observe the temperature levels or other settings and adjust appropriately. More so, if you get an AC with remote control, you can adjust the settings by looking at the LCD without getting up.
Some displays show cool colors like red or blue, which changes the look of the room. These colors are always appealing to the eye.
Well, air conditioners are not only designed for cooling rooms. Some incorporate the heating option that allows the unit to increase the room’s temperature. This option helps during winters as the room tends to be so cold.
The option is a plus for your AC as you will use it both in summer and winter. The AC is beneficial in both extremities; therefore, you will get value for money.
The filters are necessary to trap dust particles and allergens that try to find a way through the wall air conditioner. A good filter should be easy to clean as you will routinely clean it for optimal performance.
Besides, the filter should be replaceable. Failure to routinely clean or replace the filter will cause the unit to malfunction. A filter with dust particles will be heavy, thus demands more energy for performance.
Most of the wall air conditioners are not dead silent, but those that produce much noise are not recommended. Noisy units distract communication and are usually placed outside. However, the through-the-wall unit must be placed inside the house, so silent ones are the best.
The struggle to comfortably hear your TV or music sound while the AC operates at a higher sound is hectic. Furthermore, sleep is healthy and requires a quiet environment; therefore, you need to settle for a quiet air conditioner.
A good through-the-wall air conditioner should allow you to set various modes of temperature depending on the weather. The modes include dehumidification, fan-only mode, and sleep mode.
These options are all beneficial. Sleep mode allows the unit to switch off when idle. The more the modes, the more advantageous the air conditioner will be.
The final feature to look for in the smallest through-the-wall air conditioner is the wall sleeve. The wall sleeve supports the air conditioner when mounted and keeps it from contacting the wall’s parts.
The sleeve can be part of the package, or you will be forced to buy it separately, depending on the dealer. The wall sleeves are made differently, so you will have to check if it is compatible with the AC you’ve bought.
