Window Air Conditioner Review GuideSummer is a great time to get outdoors and enjoy many of your favorite activities. Whether you’re lounging by the pool, spending a Saturday at the lake, or having a cookout with friends and family, the warmer weather brings about a lot of fun outdoor activities. However, once you’re done being outside in the heat, you want to come home and cool off.

If you don’t have a properly working air unit or if the unit you have just can’t pull a heavy load when it gets very hot outdoors, you may dread the summer and the hotter temperatures. Don’t sweat away the summer when you can easily cool down with a quality window air conditioner.

Guide: What is a Window Air Conditioner?

A window air conditioner is a cooling unit that is placed inside of a window. It works similar to other cooling units in that it draws out warm air from the interior and dispenses it back into the atmosphere. Outside air is then sucked in, cooled through a compressor and released back inside the interior of the home, making the room much cooler.

These units can be installed in almost any window, can be moved as needed, and are ideal for cooling off smaller spaces, whether it’s a small home or an upstairs room that doesn’t get enough cool air from your central cooling system.

What are the different types of Window Air Conditioners?

The primary difference in window units is the size. You’ll want a larger unit to cool a bigger room or multiple rooms at once, or a smaller one for tighter spaces. However, there are a few differences that will affect the functionality, price, and convenience, which is why these units are separated into two separate categories, basic and high-end units.

Basic units can efficiently cool a room, but they don’t have all of the bells and whistles you’ll find on other models. These are usually the most affordable and have basic settings, like High, Low, and Fan.

High-end units have many more features, but they also come at a more expensive price. These may have digital controls that allow you to set a specific temperature and may even have a remote control.

What are the Advantages of Owning a Window Air Conditioner?

If you don’t have an adequate cooling system in your home, a window unit (or several placed throughout your home) can keep you cool all summer long. These are also great for use in upstairs rooms that may get stuffy. Because heat rises, it is difficult to keep your second story rooms as cool as the first.

However, with the addition of a window unit, you can help keep the temps cooler in any room. These are affordable and most homeowners or renters can have them installed and running in an hour or less.

Considerations for Choosing the Right Window AC Unit

Now that you’ve decided to cool off your home with a window unit, it’s time to pick out your product. With so many different options on the market, you may not know which is best for you, and the process can be quite frustrating. Instead of losing your cool, relax and evaluate each model that you think will be best for your home. You can begin by looking at these four features, but feel free to set your own criteria for your new cooling unit.


A small, basic unit may cost around $100, while a larger top-of-the-line unit may cost closer to $1,000 or more. While it’s important to get a great deal on your purchase, you don’t want to buy a unit that is too small or won’t cool efficiently just to save a bit of money on the initial purchase price. Make sure to look at other features to make sure that they all fit your needs as opposed to just looking at the price tag.


Your air unit should cool your home for several summers, so if something goes wrong, you know it’s due to a defect. If you use your window unit as instructed and you encounter an issue, a warranty will allow you to receive repairs or a full replacement in the case of manufacturer’s defects.

Room size

You need to measure the space of the room or rooms you plan on cooling with your new unit and make sure that you select one that is designed to efficiently cool this space. Buying a unit that is the incorrect size results in rooms that are not adequately cooled and increased utility bills.


Having a lot of different settings allows you to always be comfortable, no matter how it feels outside. Being able to adjust the unit to specific temperatures is a handy feature, while fan settings circulate the air without making you too cold on cooler days.
