Window Air Conditioners Buying Guide

Den with AC

Now that you have a shortlist of the best window air conditioners to choose from, you may still have questions, and understandably so! Whether the model for you is on this list or not, it's important to know what to look for when shopping for window air conditioners.

Things to Consider


Is it important for you to be able to control your air conditioner with a remote, or is a simple turn dial manual control sufficient? Just this simple feature can determine the price tag of your air conditioner. There are even some cheap window mounted air conditioners under $100, depending on the features you require or desire!

At the top end of the market, a growing number of air conditioners are now equipped with smart technology, which allows you to view and control your unit settings while you're out and about or simply out of range of the remote. This is particularly useful if you need to check on a unit for an elderly family member, or if you're at work and need to start up or shut down your conditioning. If you're tech savvy and need these benefits, you'll definitely want to consider a smart window air conditioner

BTU and Room Size

The cooling or heating power of any device with heating or cooling capabilities is measured using BTU. BTU stands for British thermal unit. A BTU is used for measuring how much energy is needed to raise a pound of water by one degree Fahrenheit.

With a range of window air conditioners to choose from, it is imperative to buy the right size BTU output for the space you need. The most important piece of information you need to calculate your target BTU is the square footage of the room you are cooling. A smaller area with smaller total square footage can be cooled by a smaller BTU output, whereas a larger room with a higher total square footage will benefit from a higher BTU.

Here is a reference chart to get an idea of what size BTU your room may need based on its total calculated square footage.

Room size (square feet)

BTU recommendation

Room size (square feet)

BTU recommendation


5000 BTU




6000 BTU




7000 BTU




8000 BTU




9000 BTU




10,000 BTU


28,000 BTU


12,000 BTU


36,000 BTU

If you do not know how to measure square footage, it's simple.

Measure the length of the two adjacent walls. For example, if you have a rectangular shaped room, then one wall should be shorter than the other. Measure the length of the shorter wall in feet. Then measure the length of the longer adjacent wall in feet. Multiply those two numbers together and you will get the total square footage of the room you need to cool.

For example, let’s calculate the square footage of a rectangular shaped bedroom with measurements of 10 feet by 20 feet. Multiply 10 x 20, which gives you 200. Therefore, the total square footage of your bedroom is 200. According to the BTU recommendation above, a 200 square foot room should use a unit with a BTU output of at least 6000 BTU.

Bear in mind that an AC unit with too high of a BTU output for the space you have will result in the unit quickly cooling your area. While this sounds like a good thing, a quickly cooled space can also be quickly heated again by ambient air temperature when the unit is not running. Therefore, the unit will power back on again to quickly achieve the lower temperature. This cycle will repeat, which can overwork your AC unit and potentially reduce its total lifespan. This is especially important if you're cooling a small space, when you'll need to look at small room conditioners at around 5000 BTU.

A window unit with a BTU output too low for the space you have will cause the unit to potentially run continuously in an attempt to cool the space to the desired set temperature. This can result in your unit overworking nonstop. Overworked air conditioners will also last less than the typical 10-year lifespan.

Room Location

Is the room you need to cool located upstairs? If your room or area is upstairs, you will want to add roughly 10% to the BTU to account and compensate for the additional rising warm air. Therefore, using the example above, if you add an additional 10% to the 6000 BTU air conditioner, you are now at 6,600 BTU. As you generally want to be over the recommended BTU size rather than under, you would want to select a model for 7,000 BTU.

Number of People

Do you plan to cool a room that will have two or more people within it at all times? If so, it is recommended to add an extra 600 BTU per additional person. Using the example above, adding 600 BTU per person to the original 6,000 BTU gives you a total BTU recommendation of 6,600. Again, you would want to select a model above the recommended 6,600 rather than lower. This means you would want to look at air conditioners with 7,000 BTU output to adequately cool your space.

Electrical Requirements

In addition to room size, you also need to know appropriate electrical requirements.

Some larger BTU window mounted air conditioners require a 30-amp, 230 volt breaker as the plug type is LCDI 6-30P. These are all specific, necessary electrical requirements when operating a higher BTU appliance. Not only must they be installed appropriately, but adequate electrical access is required, depending on the voltage. Smaller BTU air conditioners can be powered with a simple three-prong electrical 110 – 120 volt plug-in outlet. Making sure you have appropriate electrical requirements will help determine the best window AC unit for your space. The last thing you want to do is purchase a unit that you cannot successfully install due to inaccessible or unavailable electrical requirements.

Energy Efficiency

If energy saving is important to you, look for air conditioners with adjustable fan speeds. Variable adjustable fan speeds help circulate ambient cooler air to help lower the temperature of the space without using the unit. This means less energy consumption and less cost.

You can also look for Energy Star certified air conditioners. If a unit is not certified, then look for window models with a high efficiency ratio. Keep in mind that the higher the number the better efficiency and cost saving it will be.

Programmable Timer

Does your space stay cool during the morning hours but heat up later in the day? Window air conditioners with a programmable timer allow you to run your AC during those imperative times you need. By programming your unit to run the air conditioner during those late hours in the day will not only lower cost, but it will also extend the lifespan of your air conditioner! Window air conditioners that aren't run as often or for long periods of time can last longer.

How Do Window Air Conditioners Work?

If you were to dissect a window air conditioner, you would find two important pieces of equipment: the compressor and the cooling coil. These two devices are essential in window AC units to correctly regulate and control the desired air temperature within your designated area.

As soon as the unit is powered on to cool, the condenser starts. When the condenser starts, the cooling coil drops in temperature, cooling the air that is being pulled through it. This produces cooled air to be distributed into your space. Depending on the BTU output of the window air conditioner determines the approximate total area the air conditioner will cool.

Air Conditioner Maintenance

Do you use your AC year-round, rather than just during those hot summer months? Do you sometimes forget to change or clean the air filter? Do you have an inadequately sized air conditioner for the space you need cooled? These are all factors that go into determining how long your window air conditioner will last.

Change the Filters

While the typical lifespan of a window AC unit is approximately 10 years, this can be extended with proper care of your air conditioner. All air conditioners will benefit from regular filter cleaning and changes. A dirty air filter may cause the air conditioner to work harder to pull in clean air for recirculation, resulting in a dirty, overworked cooling coil. Therefore, it is important to change the air filter frequently.

Try to find a model with an alert to notify you when the air filter needs to be checked. With this reminder, you can successfully clean or change the air filter during the recommended times, resulting in a properly maintained window AC unit. In addition to changing or cleaning the air filter, wipe down the condenser and cooling coil. These two mechanisms collect dust and dirt during the air circulation process. The buildup of dust and dirt can result in an overworked system. This overworked system can lower the lifespan of your window air conditioning unit as well.

Clean the Drain System

Proper maintenance is not just limited to how often you clean your window AC unit and its respective components. There are other factors that go into extending the longevity of your window air conditioner. Some air conditioners have a drainage system where condensed water is released, and it is important to clean this mechanism as well. A blocked drain system can result in an overworked air conditioning unit as well, shortening its lifespan. Clean this drain system frequently, including the tubes and drain pan, to ensure sufficient draining. Sufficient draining allows the system to work sufficiently, rather than difficultly. A system having a difficult time operating creates additional obsolescence on the unit. And, you guessed it, shortening the lifespan of your air conditioner.


And there you have it! You may not have realized how many things you need to consider when looking for the best window air conditioners, and we hope we've managed to make things clearer. Whether you're looking for efficiency, quiet use, remote controls, simple manual controls, smart-home equipped, or affordability, our reviews should have you covered.
