AC size, efficiency & noise are important factors to consider when choosing the best through-the-wall air conditioner for your home.

When the temperature rises and the humidity soars, your home can quickly become an unbearable environment. While central air conditioning is great for cooling the entire house, it can be costly when you only need to cool one room. And if you have a windowless room, finding a cooling solution can be even more challenging. This is where a through-the-wall air conditioner comes in handy. It functions like a window air conditioner but is installed in a hole in the wall, preserving your window space for fresh air and a view of the outside.

Choosing the best through-the-wall air conditioner that suits your needs can be a tough decision. In this article, we will introduce the 7 best through-the-wall air conditioners available on Amazon and provide important factors to consider when purchasing one.

What to Consider When Choosing the Best Through-The-Wall Air Conditioner?

When buying a new air conditioner, there are several factors to keep in mind:

1. Air Conditioner & Room Size

The size of the air conditioner is crucial to finding the best through-the-wall unit for your room. An oversized unit will turn on and off frequently, resulting in quick cooling but inadequate moisture removal. A unit that is too small will struggle to reach your desired temperature settings. To find the right size, measure your room in square footage and match it with the cooling capacity of the air conditioner measured in BTUs (British Thermal Units).

2. Smart AC Controls

If you want to automate your room's climate, look for smart features when purchasing a wall AC unit. Alternatively, you can choose a budget-friendly unit and pair it with a smart AC controller. With a smart AC controller like Cielo Breez, you can control all your AC settings from your phone and make changes on the go. This includes scheduling, geofencing, Comfy Mode, and voice commands. Smart AC controllers not only provide comfort but also help reduce unnecessary energy usage and cut down on AC costs.

3. Installation Location

Through-the-wall air conditioners are perfect for areas without ductwork, such as garages or backyard sheds. When choosing the installation location, ensure there is enough space around the exterior side for proper ventilation and airflow.

4. Energy Efficiency

Check the energy efficiency ratio (EER) of the air conditioner before making a purchase. A higher EER indicates better efficiency. Look for the Energy Star label, as it signifies that the unit meets government-backed energy efficiency standards. Energy Star ACs can save up to 9% more energy compared to other models.

5. Thickness of Your Wall

Ensure that the thickness of your wall is equal to or greater than the depth of the metal sleeve that holds the air conditioner in place. Most sleeves can fit walls that are 8 inches thick or less.

6. Types of Sleeves

Wall units can have either a slide-out chassis sleeve or a fixed sleeve. Removable sleeves make it easier to service or replace the unit. When replacing your unit, make sure to buy one that fits your existing sleeve perfectly.

7. Electrical Requirements

Most through-the-wall air conditioners use a standard 115V outlet. However, high-output models may require a 230V connection, which would require special wiring in your home.

8. AC's Noise Level

Keep in mind that through-the-wall air conditioners tend to be slightly noisier compared to other units. They generate around 50 decibels of sound, comparable to moderate rain or light traffic. If you plan on using the AC in a nursery or home office, look for a unit with a low noise level (around 30 decibels).

9. Heat Function

Many through-the-wall units also provide heating options. This eliminates the need for separate heating and cooling units. You can use it as a stand-alone heating system or as a supplement alongside a central unit.

10. Extra Features

Consider additional features such as sleep mode, fan-only mode, touch and voice controls, remote control, dehumidifier mode, adjustable louvers, antibacterial air filters, and digital control. These features enhance the functionality and convenience of your air conditioner.

11. Room Aesthetics

If you're concerned about the appearance of a bulky wall unit, there are ways to hide it. You can try enclosing it in a cabinet or decorative box when not in use, or use a colorful folding screen to cover the front.
