1. Best Overall: FRIGIDAIRE FFRE0833U1 White Air Conditioner
While it’s a great choice for anyone looking for an effective way to stay cool in the hottest summer days, this model’s features make it especially recommendable to individuals with allergies.
Our top recommendation for a window air conditioner is the Frigidaire FFRE0833U1, thanks to its cooling power, energy efficiency, and versatility. This air conditioner can cool small-to-medium sized rooms very quickly and economically. While it’s a great choice for anyone looking for an effective way to stay cool in the hottest summer days, this model’s features make it especially recommendable to individuals with allergies.
One of the best features of this air conditioner is that its thermostat is, in a way, more “objective” than those of competing brands. The thermostat of the Frigidaire FFRE0833U1 is on the remote control rather than on the body of the AC. While other units think that the temperature is warmer than it actually is (as their thermostats are nearest to the window), this unit reads the temperature inside the room, providing a more accurate cooling response.
Another thing to love about this AC unit is that it’s energy-efficient. The Frigidaire is Energy Star certified, and at 12.0 EER, it’s an economical and eco-friendly choice for the home.
This AC unit’s BTU is 8,000, (a product’s British Thermal Units determine its capacity to cool a given square footage) which make it ideal for rooms up to 350 square feet. Unless placed in a larger room, this powerful unit has one of the fastest cooling speeds of any window AC.
Another thing to love about this AC unit is that it’s energy-efficient.
The top features of this unit which make it ideal for allergy sufferers are its dehumidifier and its clean-air Ionizer. The Frigidaire can dehumidify up to 1.7 pints per hour, and the Ionizer removes pollen and other impurities from the air. With this AC option, you can say goodbye to congestion due to humidity, pollen, and pollution.
Some other cool features that allow the Frigidaire to circulate a lot of cool air are its three-speed settings and an adjustable airflow in eight different directions.
Lastly, customers have said that this unit is very easy to install!
While the Frigidaire is powerful, customers have complained that the unit can run loud.
2. Best for Large Rooms: FRIGIDAIRE FFRA1222U1 Air Conditioner
While most window air conditioners are best suited to smaller rooms, the Frigidaire FFRA1222U1 has the capacity to cool larger rooms as well. This air conditioner is recommended for people looking for an affordable window air conditioner that will quickly cool the larger rooms in your home, like the living room, or an entire studio apartment.
One of the most attractive features of this air conditioner is its capacity to cool large spaces. At 12,000 BTU, the Frigidaire FFRA1222U1 can effectively cool a room with a size up to 550 square feet. Considering the high capacity for cooling, the Frigidaire is a great value-for-money choice.
Another thing to love about this window air conditioner is its versatility. The Frigidaire can be operated via remote control or directly on the AC unit’s body, and comes with three speed options, a 24-hour on/off timer, and it also features settings such as energy efficiency, auto-cool, and sleep mode. Additionally, like the Frigidaire FFRE0833U1, this AC unit can easily be programmed to direct airflow in any direction needed, as its design includes an 8-way direction adjustment.
One of the best features of the Frigidaire is that it is also a strong dehumidifier, and can dehumidify up to 3.8 pints per hour, making it a good choice for hot and humid climates.
This AC unit comes with a 1-year full warranty and a 5-year sealed system warranty.
One of the issues with this model is that it isn’t Energy Star certified, so it’s not the most energy efficient choice on our list.
Another issue with this unit is that while it has easily removable and washable filters, which work well in trapping bacteria, they do fill up with grit and residue frequently, so they need to be cleaned regularly.
Additionally, while this is one of the most powerful window air conditioners, it is not our quietest recommendation.
Lastly, some customers have expressed that the packaging of the product may be somewhat flimsy, causing it to arrive with small dents from transportation.
3. Most Quiet: Friedrich CP08G10B Air Conditioner
This model is also energy efficient, and one of our most stylish recommendations.
The Friedrich CP08G10B Air Conditioner is the quietest recommendation on our list. It produces about half the noise of competing brands. This makes it a great choice for bedrooms or small offices, where you don’t want to be distracted by noise. This model is also energy efficient, and one of our most stylish recommendations.
Note: While this unit is cooling-only, the same company does offer models that have heating features as well.
One of the best features of the Friedrich is that it comes with ultra-quiet operation, which means that no matter what speed setting you set it to, this AC unit makes minimal noise. Satisfied customers have reported that this is the quietest AC unit they’ve ever purchased.
The Friedrich has a capacity of 8,000 BTU, which means that it can cool any room up to 300 square feet. Although this AC unit is not the quickest to cool a room, it does maintain the temperature very efficiently and steadily once it reaches the desired degree. The auto air sweep louvers automatically oscillate to spread the cool air in all corners of the room.
The Friedrich comes in a sleek, elegant design, which makes it a great addition to small spaces.
Another thing to love about this product is that it offers versatility in both modes/settings and installation. In terms of settings, which can be selected on the AC’s body or via remote, the Friedrich includes multiple speeds, a 24-hour timer, and a “money saver” mode. While the AC unit itself is Energy Star certified and energy-efficient, the “money saver” mode allows you to operate the fan only, which is even more budget-friendly.
In terms of installation, this AC unit can be installed both in a window and through a wall up to 7.5 inches thick. This is the only AC unit that offers a through-the-wall installation option, which is a good option as it gives you more freedom in terms of leveling. Additionally, installing it through the wall is a good choice if you want a sturdier, more permanent place for your new AC.
Customers have reported that installing this unit was quite easy. The power cord can run on either the left or right side of the front of the unit.
The Friedrich comes in a sleek, elegant design, which makes it a great addition to small spaces.
This AC unit has a 1-year full warranty and a 5-year sealed system warranty.
This AC unit is on the pricier side, so it’s not a great choice if you are looking for something more budget-friendly.
Additionally, the thermostat on the Friedrich is not among the most accurate ones on this list. Yet, as you can adjust the temperature of the unit, and it’s highly efficient at maintaining the desired temperature in a room, this isn’t a very big issue.
4. Most Budget-Friendly: Keystone KSTAW05C Air Conditioner
It’s the smallest and lightest window AC among our top choices.
The Keystone KSTAW05C is the most budget-friendly recommendation on this list and is suitable for smaller rooms. It’s the smallest and lightest window AC among our top choices. That makes it great for compact spaces and portable uses.
The Keystone is a great budget-friendly choice both because of its price at purchase and its low energy consumption. It’s Energy Star certified, with an EER rating of 12.2. Additionally, as it has 5,000 BTU, it uses less electricity than other units. Still, this also means that it can only be used to cool rooms up to 150 square feet, and is not very efficient for spaces that surpass that size.
The Keystone is quite compact. Each of its dimensions is less than 20”, and it weighs less than 40 pounds so that it can be easily installed and mounted on any window. Plus, it can just as easily be transported or stowed away for the winter.
For an AC unit that’s so compact and affordable, the Keystone still comes with a variety of useful features that you rarely find in competing units. To begin with, it has three cooling settings and three fan settings, for even lower energy consumption. It has a remote control, a timer, and settings such as auto mode, sleep mode, and even a dehumidifier. The dehumidifier can absorb humidity at up to 1.3 pints per hour, which is also impressive for its size.
Another rare feature among products in this category that the Keystone has is an auto-restart function, which saves all your settings for when power is restored to the unit.
The Keystone comes with a 1-year full warranty and a 5-year sealed system warranty, which is longer than any other AC unit in this price range.
The Keystone has low maximum airflow and quite a limited directional airflow, which make it unsuitable for any rooms that surpass 150 square feet.
Additionally, while most customers have reported that the Keystone operates quietly, several users have reported that their units can run loud.
The best window air conditioner is the Frigidaire FFRE0833U1, as it has the capacity to quickly cool rooms up to 350 square feet with decent energy efficiency. This window AC unit also offers great value for the money, especially considering the variety of features it offers.
The main issue with this model is that it can run loud – so if you need something quiet for a bedroom or an office, or simply don’t want to put up with noise, then the Friedrich CP08G10B window air conditioner is a great choice for you. This unit’s steep price is justified by the high quality of the build, as well as its energy efficiency, low noise level, and stylishness. Plus, this AC is great at maintaining a steady temperature.
On the other hand, if you are looking for something which is more budget-friendly for a smaller, cramped space, then the Keystone KSTAW05C is the way to go. Although it’s small and cheap, this window AC surprises with a host of useful features (such as a dehumidifier, a timer, an auto-restart) and an Energy Star rating, which means you will save money both on the purchase and while using it.
Yet, the Keystone is only good for rooms up to 150 square feet, so if you are looking for an affordable way to cool larger rooms, the Frigidaire FFRA1222U1 is a great choice that can cool up to 550 square feet. Its 8-directional airflow is great for ensuring that all cool air reaches all corners of the room.
