Window Air Conditioner Reviews Guide
A common misconception about window air conditioners is that they’re extremely loud and aren’t as powerful as central AC. However, they’ve improved significantly over the years and now include built-in energy efficiency features, programmable timers, and powerful fan speeds. As one of the more affordable options on the market, window air conditioners can save you money in the long run and keep your home cooler for longer.
If you’re thinking about purchasing a window air conditioner unit, you’ve come to the right place. With an onslaught of products available to consumers, we want to provide you with the very best options (and information) to help make your purchase decision simple and easy. Check out our top recommendations above or keep reading to learn what should be considered before you buy.
8 Major factors to consider
Small window air conditioners range from 5,000 to 6,500 BTUs and cool roughly 100–300 square feet. Though these units are the lightest and least expensive, they can’t adequately cool a room more than 300 square feet. Mid-sized machines range from 7,000 to 8,200 BTUs and can cool slightly larger rooms than smaller units. Large window air conditioners have some of the best cooling power and range from 9,800 to 12,500 BTUs. Though they can cool larger rooms, they’re a little heavier and are more difficult to install.
Most window air conditioner fan speeds can be controlled with the manual turn of a dial or a remote control. The higher the fan speed, the faster your room or house will cool down. Look for a window air conditioning unit with multiple fan speeds.
If you’re buying a window air conditioner for your bedroom and know that you’re a light sleeper, or if you get distracted easily while completing work, opt for a machine that errs on the quieter side. You don’t want to be disturbed when trying to get a good night’s sleep or have trouble focusing in the midst of a big work project.
When purchasing a window air conditioner, aim for 20 BTUs per square foot of living space and add 600 BTU for each additional person in your household. For example, if you want to cool a 150-square-foot room and live alone, opt for a 3,000 BTU unit. BTU specs are typically listed under the product description of each machine.
Directional airflow vents
Some window air conditioners have swivel vents that allow you to control the direction of airflow. These can be helpful if you have an oddly placed window and want the air to flow to the center of the room or if you want the air centered directly on you. Consider room layout and look for a model that can direct airflow where you need it most.
Most modern window air conditioners come with a remote control to help you adjust the cooling settings from anywhere in the room. If you have less accessible windows or just don’t want to get up every time you need to change the air temperature, find an air conditioner that comes with a remote control.
Some window units come with a timer that allows you to program when you want your unit to turn on. There may be some machines that even allow you to connect your smartphone, allowing you to control exactly when you want the cooldown process to begin. This feature also helps you save energy and cut down on cooling costs.
Most window air conditioners come with replaceable or washable filters. If you don’t want to constantly buy new filters for your unit, find a unit that contains washable filters. Some units will come with a HEPA filter, which can remove 99.9% of dust particles and allergens from the air. If you suffer from allergies, look for an appliance with a HEPA filter.

This unit comes with a three-speed fan, a timer, and an automatic mode that allows you to set a temperature and stick to it. It also comes with a high-powered motor and energy-saving mode that stops cooling once your desired temperature is reached.
Window AC cooling power is measured in British Thermal Units, or BTUs. The more cool air you desire (and the larger the room), the more BTUs you want.”
How to achieve optimal AC efficiency
Typically, a window air conditioner will last for roughly 10 years as long as you properly take care of it. Here are a few things you can periodically do to ensure it lasts for as long as possible.
Inspect the machine’s coils—Vacuum the coils with a brush attachment to remove dirt and debris. If one doesn’t come with the unit, you can purchase one at your local hardware store.
Clean the filter regularly—A dirty filter can make the machine work harder, reducing efficiency and leading to a possible breakdown. Check the filter every few months by popping out the front grille of the machine. If the unit uses a reusable filter, wash it with warm water and let it dry before inserting it back into the unit. If it contains a replaceable filter, make sure you have one on hand to replace it with. Look at your product manual to determine what type of replacement filters are necessary.
Look for bent coil fins—Coil fins are the narrow metal pieces that form grooves in the air conditioner. Use a fin comb (this can be purchased from your local home improvement store) to straighten any bent coil fins.

How much does a window air conditioner cost?
Window air conditioners typically range from $100–$700. The less powerful units (those that sit around 5,000 BTU) will fall on the cheaper side and work best in smaller spaces. In the $200–$350 price range, you’ll find units that typically range from 8,000 to 12,000 BTU. The more expensive models with be some of the more powerful machines, ranging from 15,000 BTU and up. Some of the more expensive units will also come with more features like heat functionality, timers, and remote controls.

Frequently asked questions
Which brand of window air conditioner is the best?
Out of all the window air conditioner brands available, we particularly love ones that are ENERGY STAR certified. Frigidaire is a brand that sells affordable units that range in price from $100–$800. Frigidaire units range from 5,000 to 28,000 BTUs.
Can you use a window air conditioner without a window?
You can’t use a window air conditioner without a window, but you can buy a portable air conditioner if you have only a small window to work with or you can install central AC as an alternative.
How much maintenance does a window air conditioner require?
Expect to clean or replace the air conditioner filter every few months—we recommend once a season. Other than that, we suggest cleaning the evaporator and condenser coils with a dust brush and straightening bent fins with a fin comb at least once a year.
