How Do Smart Window Air Conditioners Work?

Smart window air conditioners have the following components: a compressor, condenser could, and evaporator coil. Each component plays a particular function to ensure that the smart air conditioner effectively cools the air in the room and reduces humidity in the air indoors.

Smart window air conditioners have a special type of fluid called a refrigerant. The compressor in the air conditioner turns the refrigerant into a gaseous form.

The gas has a very high level of pressure and temperature. The gaseous refrigerant is directed to the condenser coil. The function of the condenser coil is to turn the high-pressure and high-temperature gaseous refrigerant into a fluid.

As the fluid passes through the evaporator coil, it absorbs heat and moisture from the warm air. The air full of heat is then pumped outside the building while cool air currents are continuously directed inside the building.

The moisture that is collected from the air is also discarded. Through this method, a smart window conditioner repeatedly changes hot and humid air into cool air with the right amount of moisture.

Benefits of a Smart Window Air Conditioner

A smart air conditioner may be the right device to cool the air in your house or office. The following are some of the main benefits of using a smart window air conditioner.

Easy to Operate

Smart window air conditioners are Wi-Fi-enabled. You can connect them to the network of the smart devices in your home using common applications such as Google Assistant and Alexa.

By using voice commands, you can determine how your smart air conditioner operates. This means that you no longer must use manual controls to adjust your air conditioner mode of operation.

Little Space

Unlike portable air conditioners, smart air conditioners utilize very little space. You need to create a lot of space for your portable air conditioner near the window. Occasionally, if you intend to move it to a different room, you must choose the right place and move the venting in the process.

A smart window air conditioner is mounted on the windowsill. It remains there if you would like it to be in that spot. You do not need to clear space on the floor of your house to place your smart window air conditioner, as is the case with a portable air conditioner.

High Energy Efficiency

Compared to portable air conditioners, smart window air conditioners are highly energy efficient. This type of air conditioner is designed to utilize energy optimally to cool and dehumidify the air in your room.

Many brands of smart air conditioners have an EER value of more than 11. This means that you will not have to pay a lot for cooling costs when installing such a smart window air conditioner in your building.

Silent Operation

Smart window air conditioners are less noisy than conventional portable air conditioners. You can comfortably leave your smart window air conditioner running the entire night without getting distracted by the noise of its fans.

How to Convert a Regular Window AC to Smart AC?

Operating a regular window air conditioner is quite cumbersome. You need to physically turn the machine on and off whenever there is a need for doing so. Moreover, window air conditioners are designed to cool the air in one room.

Residual cooling of the air may occur in the adjacent room; however, this largely depends on the nature of the openings between the rooms. If you have multiple window air conditioners in the room, you will have to turn them on and off every time manually. This is not practical.

Smart air conditioner solves this problem because they let you program your device and control it remotely. You can use Alexa or Google Assistant to issue commands to your smart window air conditioner. Sadly, smart window air conditioners are quite costly.

It is possible to forego the costs of purchasing a new smart air conditioner and avoid the trouble of running a conventional window air conditioner. All that you need to do is use a smart plug.

A smart plug is a small device you install between your conventional air conditioner and the power outlet. The plug lets you program and control your air conditioner as if it is a smart air conditioner.

You can download an app and even use it to integrate with Google Assistant and Alexa. This, effectively, turns your conventional air conditioner into a smart window air conditioner.

Here is how to go about the process.

1. Check if your regular air conditioner is compatible with a smart plug

Smart plugs work with a regular air conditioner that has full manual controls. The controls should be mechanical and not the soft buttons with digital displays, which some regular air conditioners have. Check your conventional air conditioner to ensure that it has fully mechanical control knobs and not soft buttons with digital displays.

2. Purchase a smart plug

There are multiple brands of smart plugs currently available on the market. The prices range of smart plugs may be anywhere from $20 to $40. All of them allow one to download a particular app on their mobile phone.

3. Connect the smart plug with the air conditioner

Put the smart plug in the power outlet and then connect the air conditioner to the smart plug. This means that you would have effectively transferred the control of the entire air conditioner to the smart plug. The switching of the smart plug automatically turns off the air conditioner.

4. Program the smart plug using the installed app

You can also use the app to integrate the smart plug into your favorite software, including Alexa and Google Assistant. Test it to ensure that it responds correctly to your voice commands and other remote-control maneuvers.

Other Things to Consider When Choosing a Smart Window Air Conditioner

Size or cooling capacity is not the only factor you should consider when choosing a smart air conditioner.

Here are other equally important factors that one should carefully consider before settling on a smart air conditioner brand.

Type of Refrigerant

The best smart air conditioners are those that have eco-friendly refrigerants. Eco-friendly refrigerants produce minimal amounts of hydrofluorocarbons.

Hydrofluorocarbons are very harmful because they contribute to the depletion of the ozone layer, and eventually, global warming and climate change.

One of the recommended types of refrigerants that are used in smart air conditioners is called HCFC-22. Go for air conditioners that have this type of refrigerant or others related to it.


Although the safety level of smart air conditioner has dramatically improved over the years, you still need to consider it when choosing a device for your home.

Modern air conditioners are safer than the old brands. They have been subjected to rigorous tests to determine the cords’ ability to withstand shocks and prevent fire outbreaks. Go for air conditioners that have the best and most-recognized safety standards.

Noise Levels

Smart window air conditioners produce noise because of the functioning of the fan and vibration. When set on very high fan speed modes, the air conditioners tend to louder than when they operate on low fan speed modes.

It makes sense to purchase a smart window air conditioner with a low noise level of less than 40dB than one with a high noise level. Noisy smart air conditioners can make it very difficult for you to sleep peacefully at night.


Smart window air conditioners come with installation kits. These are the hardware that you can use to get the air conditioner up and running. You use them to properly attach the air conditioner to the window of your house.

The installation process differs with the size of the window. Luckily, today’s smart air conditioner brands have wide ranges of the minimum width of windows where they can be installed.
