1. Frigidaire FFRH1822R2
Check Price at Amazon
Summary: This unit is very powerful and long-lasting. Thanks to its 8-way air direction control that allows you to select which way you prefer the cold air to go, as well as the 24-hour timer, you’ll be able to personalize its operation according to your needs and schedule. Additionally, due to the memory function, you won’t have to worry about power cuts as it will easily restore the settings once the power returns after an outage.
Pros:
- 8-way air control
- Auto-save and auto-restart functions
- 3 fan levels for faster cooling
- Versatile with both cooling and heating ability
- Can dehumidify 5.5 pints/hour
- In-wall and window installation
Meet performance at its highest standard with this innovative and powerful AC that offers a
cooling power of no less than 18,500 BTUs. Plus, another 16,000 BTUs enable it to provide heating in rooms measuring up to 1,050 square feet. If you have a larger area that you need cooling for, say a 550 square feet space tops, then you are better off with the
Frigidaire FFTA1233Q1 that is rated at 12,000 cooling BTUs.
The FFRH1822R2 is simple to use, with a large control panel with clear controls and a remote that allows changing settings from afar. It measures 23 5/8” wide, 17 5/8” high, and 25 3/8” deep, and it weighs 118 pounds. The wall you plan on installing it through shouldn’t be thicker than 8 inches, and the frame it includes measures 18” in height and 23 7/8” in width. It can also support window installation using the included kit, and it has a limited warranty of 1 year from the moment of your purchase.
Performance and Controls
It features 3 fan speeds and upholds a silent operation regardless of the speed setting you select so that you can run it day and night without the unit posing a distraction. It creates 54 decibels on low and 60 decibels when on high speed – and thanks to its 8-way air path control, you can easily select in which way you wish the cold air to go first.
With the Sleep Mode activated, it will create a pleasant ambiance during the evening by gradually regulating the temperature. Since it boasts a high BTU rating, it can become the main cooling and heating source in your home. Thanks to the slide-out chassis, it can be simple for you to mount it without expert help.
The 24-hour timer lets you set a working schedule to avoid electricity waste without sacrificing comfort. Moreover, if the unit turns off due to a power shortage, it will immediately turn on as soon as the power comes back, continuing to operate with your pre-selected settings.
Cleaner air
This isn’t a regular AC unit that simply modifies the temperature - it works as a dehumidifier that takes out the moisture from the air too. While it does that, it manages to purify the air using a washable filter that gathers dust particles. Another convenient feature stands in the alert that notifies the user when the filter requires cleaning.
Performance Test Feedback
It’s hard to say what impresses more when it comes to this Frigidaire AC – the cooling and heating abilities, or the multitude of purposes it serves. After testing and observing it during summer and autumn, what I can testify is that you won’t need supplemental cooling or heating once you set it up. Keep the doors open between rooms and you won’t need to turn up the heater when the weather gets cold. My only complaint since installing it is that at the highest speed, it does get a bit noisy. I always turn it on to the lowest setting when I’m in the room, otherwise, I would only focus on its humming. Other than this, there’s no downside to this air conditioner. It works year-round and really keeps you comfy indoors, you’re cool when the torrid summer comes and warm when the cold weather strikes. It’s as easy to use as they come, but this is a commonality with modern ACs. You are the master of the AC since you can control the 8-way air direction. Even maintenance isn’t much work; the filter is easy to get out and clean when it gets too dirty.

2. Whirlpool WHAT142-2AW 14,000 BTU
Summary: The fairly large area coverage of this AC makes it a fan favorite, hands down. It’s suited for spaces of up to 700 square feet, which makes it an effective solution to keep larger areas like the living room or office cool. The fact that it integrates all the modes and features we have come to expect from ACs is a highlight on its own as well. Best of all, it’s an energy-efficient option that you can run as much as you like without worrying about costs.
Pros:
- Universal fit with available sleeves that measure from 24.5” to 27” in width
- Quick access to the filter – pull the front handle to reach it
- Can remove upward of 2.1 pints of moisture per hour
- The on-board electronic control panel makes it intuitive to use
- Use the Eco function to save on the utility bill while running the AC
Cons:
- This product isn’t Energy Star certified
- It’s a bit noisy
This Whirlpool AC is one of the most flexible options at the moment, a perk that is granted by the 8-way directional louvers for even cooling. Installation is as stress-free as it gets, especially considering that it is a universal fit – almost, at least.
It’s suited for wall sleeves that measure from 24.5” to 27” inches, and you’re not obliged to go Whirlpool. For example, Amazon’s suggestion when it comes to the right wall sleeve is a Keystone model, namely the KSTSLV1 version. The AC measures 20.3” in depth by 24.2” wide by 14.5” in height. With the package, you also receive a trim kit and rear grille.
It features a total of three fan speeds to pick from, as well as four operating modes. These include Cool, Dry, Fan, and Auto. If you want to take the easy route and not have to adjust settings at all while it runs, use the pre-programmed functions instead. It features two, namely Eco Function and Sleep Function. The Eco option switches off the compressor when the room temperature reaches a specific level to save energy. On the other hand, the Sleep option raises the temperature while you sleep to keep you comfortable while saving power.
Woefully, the product isn’t Energy Star certified. Don’t get us wrong, running it won’t necessarily be a costly endeavor, especially if you use it in the aforementioned Eco mode. Nevertheless, it will draw significantly more power than Energy Star AC units like the Keystone KSTAT10-2C. So you might be better off with this alternative option from Keystone if you want to lower AC operating costs as much as possible.

3. LG LT1037HNR
Check Price at Amazon
Summary: Seeing how it functions as both a cooling and a heating unit, you can use this LG year-round. Moreover, the 4-way airflow direction control guarantees that cooling and heating are provided evenly throughout the room.
Pros:
- Intended for cooling and heating purposes
- Compatible with already existing 26” mounting sleeves
- It removes excess moisture from the air that it pulls inside
- Multiple working modes – fan, cool, heat, dehumidify
Cons:
- Not the cheapest pick you could opt for
- The included matching sleeve is slightly bigger than the unit
With a cooling power of around 10,000 BTUs and a heating capacity of 11,200 BTUs, this AC is suited for
rooms up to 440 square feet in size. It is one of the few systems that you can count on for year-round use, the only other product we reviewed that provides both cooling and heating being the
Frigidaire FFRH1822R2. This top-rated product is recommended for larger areas (
1,050 sq. ft.), however, so it might not serve your needs as well if you seek a smaller capacity model when it comes to coverage. It has 3 speed levels that allow you to adjust the intensity with which it cools or heats the room, offering you the possibility to use the unit year-round. It measures 20.1” in height by 24 in width by 14.4 in depth and it weighs 70 pounds. The size of this product implies that you can pair it with existing wall sleeves measuring 26 inches wide.
The energy efficiency ratio of this model is 9.8. Aside from its function as an air conditioner it also works as a dehumidifier – it removes up to 3.2 pints of moisture per hour. When it pulls the air inside, the incorporated filter eliminates polluting particles to protect the unit from damage and help clean the air inside the room. It features a rotary compressor with an R410A refrigerant, and it doesn’t make much noise when it runs – from 54 to 61 decibels.
It is packed with multiple features, including thermostat control, a 4-way airflow direction, a 24-hour adjustable timer, and an energy-saving setting. The digital controls provide an intuitive means to set the desired temperature from 60 to 85 degrees Fahrenheit, set up the timer, and select the preferred operation mode (pick from energy saver, cool, fan, or heat). The LED indicator lets you know when the filter needs to be washed. The included remote provides a convenient means to change the settings from afar. Before we end, we must mention that the product is covered by a 1-year warranty.

4. Koldfront WTC14012WCO
Check Price at Amazon
Summary: Considering that it is rated at 14,000 BTUs cooling power, this is a great option for people who are dealing with torrid summers and want to escape the heat when they’re at home. It’s simple to operate and lets you even direct the way in which the cold air flows, creating perfect living conditions even for the most pretentious users.
Pros:
- A hefty screen with visible controls
- 4 fan speeds for better optimization
- Strong and silent
- Washable filters
- Dehumidifier function when used in dry mode
Specially made for through-the-wall installation, this is your go-to choice if you want a compact but powerful AC. It measures 14-1/2” in height by 24-1/4” in width by 20-3/8” in depth and requires a WTCSLV wall-mounting sleeve that isn’t included in the package and that measures 15-1/4” in height by 25-1/2” in width by 17-1/2” in depth. It has a 14,000 BTU capacity and it is
recommended for spaces measuring 550-700 square feet. If you want a product suited for smaller spaces, Koldfront has you covered. The
Koldfront WTC8002WCO is the right option in this scenario. Rely on this 8,000 BTUs model to cool spaces of up to 350 square feet ASAP.
The energy efficiency ratio of the WTC14012WCO is 9.4, and you can set the temperature that it should maintain in the room from 62 to 86 degrees Fahrenheit. The power cord measures 6.5 feet in length, an aspect you must take into account when you pick the exact installation place for the unit if you don’t want to end up using extension cords. The intuitive controls and large digital display make it easy to operate even for first-time owners.
The package includes a remote control to change the settings from afar. There is an internal fan with 4 speed settings, namely low, medium, high, or auto. The adjustable louvers are another mention-worthy perk since you can use them to direct the cold air where you wish. The filters help improve air quality in the room while protecting the AC from damage since their purpose is to trap impurities lingering in the air the unit pulls in.
For added convenience, a timer was added to let you customize the working schedule and limit energy usage. It’s relatively silent, at 59 decibels on the higher level, and it can also be set to a Dry mode that dehumidifies the air. In the Sleep mode, it will raise the temperature during the night, returning it to your settings first thing in the morning. When it comes to backing, the manufacturer covers repairs during the first 2 years after you make the acquisition.

Summary: Easy to use, with a conveniently-placed control panel that is easy to access, it will quickly help cool the room. It comes with a remote control that serves as a portable thermostat so that you can always keep an eye on the temperature, while the timer will allow you to set the duration of its operation as you like to cut on running costs.
Pros:
- High power and extended coverage – rated at 12,000 BTUs and covers areas of up to 550 sq. ft.
- Dehumidifier function – removes 3.3 pints of moisture per hour
- Energy-saving mode reduces operating costs
- Adjustable louvers for airflow direction control
Cons:
- It’s not compatible with many sleeves
- There were some complaints about its noise level
This model belongs to the “Chill” series from Frigidaire and it is one of the most efficient AC units in terms of cooling homes or commercial spaces. There are two installation options available: through the wall or inside a window sill. This particular model is
rated at 12,000 BTUs cooling capacity, but there are other options in the same series with it that range from 5,200 BTUs to 24,000 BTUs. Thus, in case you’re looking for a different capacity model but want it to have the same specs as this one, Frigidaire has you covered.
This model measures 23.6 inches in width by 21.75 inches in depth by 15 inches in height, and it weighs 87 pounds. It can cool a room of approximately 550 square feet and it is rated at 330 CFM. The Auto Air Sweep feature provides consistent air distribution throughout the room thanks to the louvers that are in a constant swinging motion. The control panel provides an intuitive means to pick between the 4 operating modes – fan, cool, money saver, and dry. When used in the dry mode it acts like a dehumidifier and extracts up to 3.3 pints of moisture per hour. It features 3 fan speeds – low, medium, and high. Moreover, it features a timer that lets you set the span of its operation as you like to limit power draw.
Thanks to the thermostat, you can monitor the temperature in the room and set it from 60 to 86 degrees Fahrenheit. It includes a washable anti-microbial filter that clears the air pulled in by the AC of impurities to provide you with clean air to breathe and keep the internal parts of the unit safe from damage. Woefully, it’s likely that you will need to clean the filter every couple of weeks, which is a bit bothersome. It features the automatic restart function that saves your preferred settings so that you won’t have to reinsert them when the power comes back after an outage. It is accompanied by a 5-year warranty from the moment of purchase.

6. Keystone KSTAT10-2C
Check Price at Amazon
Summary: This AC provides you with full control over its operation and lets you customize the temperature that it should maintain as you deem fit. The remote control functions like a portable thermostat, so you can check the temperature wherever you go. Additionally, it provides 3 speed settings to pick from and 4-way adjustable airflow control to direct the cool air in whatever area of the room you want.
Pros:
- The filters can be cleaned instead of replaced
- The remote control works like a thermostat
- 3 fan speeds and 4-way air direction control
- Incredibly silent – produces from 54 to 58 dB
Cons:
- Rather difficult to mount
- Some complained about it not fitting with already existing wall sleeves
This
10,000 BTU AC unit can cool down a room up to 450 square feet, and you can rely on it to also work as a dehumidifier, removing the moisture present in the room with a rate of 55.2 pints per day. Since it is rated to produce only 54 dB on the low speed and 58 dB on the highest speed, it won’t present a nuisance even if you set it up in the bedroom or office, rooms where ruckus is something that you must avoid. It measures 14.5 inches in height, 20.3 inches in depth, and 24.2 inches in width, and it weighs 69.3 pounds.
It is Energy Star certified and flaunts an EER ratio of 10.6, so you won’t see a noticeable rise in the electricity bills once you start running it. The remote works as a portable thermostat, so you can check the temperature at all times while also enjoying the perk of selecting the settings you prefer from 20 feet away from the AC. There are 3 fan speeds that you can pick from and the 4-way air direction control ensures the room is cooled evenly and in the pattern that you prefer. The only other model we reviewed that’s more impressive when it comes to air direction control is the top-rated Frigidaire FFRH1822R2 that features 8-way control.
The 24-hour timer lets you pick for exactly how long the unit should run unremittingly to save on costs. It features the energy-reducing mode that you can activate when you want to cool the room in the most cost-effective manner possible, as well as the Sleep mode that adjusts the settings so that you can sleep in the same room with the AC without it posing a distraction while you try to rest. Warranty-wise, you can expect the manufacturer to cover the product against defects for 1 year after you acquire it.

7. Perfect Aire 4PATW10000
Check Price at Amazon
Summary: This AC provides a truly quick way to cool down the room you place it in, and it even lets you put together a schedule for it via the timer setting. The air-directing louvers permit you to decide in what direction the cold air should flow, while the remote control acts as a portable thermostat. These are only some of the reasons why this Perfect Aire unit makes for a deal that’s hard to pass on.
Pros:
- Programmable timer lets you schedule the operation of the AC
- Energy saving setting reduces operating costs
- Compatible with several types of wall sleeves
- LED indicator light shows when filter cleaning is due
- The remote control acts like a thermostat due to the Follow Me function
Cons:
- The mounting sleeve is not included
- The installation indications are vague
If you are on a tight budget, you should have a look at this model. It’s
a 10,000 BTUs unit that can handle medium-size spaces of 450 square feet. The manufacturer also offers an 8,000 BTU and a larger 12,000 BTU version, so you have your pick if you like this model but seek a different cooling capacity AC. It measures 24.25 inches in width, 14.5 inches in height, and 18.5 inches in depth, and it weighs 68 pounds. It can work with several wall sleeves, but they should be between 25-1⁄2” - 27” in width, 15-1⁄4” – 16-3⁄4” in height, and 15-7/8” – 22” in depth.
Operating it is straightforward: it features a large control panel with a big screen and light indicators for each setting. You can select between multiple speed settings – low, medium, and high. When it comes to the operating modes of the AC, these include Auto, Cool, Dry, and Fan, plus the Energy Saver setting and the Sleep mode for nighttime use. It doesn’t make much noise when it runs – 53 dB on low, 55 dB on medium, and 57 dB on high.
If you simply want the unit to circulate the air in the room instead of outright working to reduce the temperature, then you can run it on the Fan mode. It features a timer that you can set to find the room cool when you arrive from work. The timer also serves as a power-saving option since you can limit the operation of the AC to what is strictly needed. The Follow Me option lets you control the unit from a distance with the remote control that acts as a thermostat, displaying the temperature as well as the other settings, so you’ll always be in control. This same mobile thermostat option of the remote control is present with the better rated Keystone KSTAT10-2C, so you have alternatives if you are keen on an AC that flaunts this perk.
The 4-way directional air louvers let you redirect the cold air in multiple directions. While it cools the air, it also takes out dust and impurities using the included filter that you must routinely clean. When this task will be required, a LED light will turn on to notify you. Lastly, there is a 1-year warranty from the moment of your purchase that spares you from costs in case the unit becomes defective.

8. AMANA 12,000 BTU Thru-Wall Air Conditioner
Summary: If you want to be smart with your money, this Amana product might be your best choice. Since aside from the classic Cool, Fan, and Energy Saver modes, it also features the Heat mode, this is a year-round use AC that is worth every cent.
Pros:
- Pick between multiple running modes, including Heat
- The 4-way adjustable airflow direction lets you focus the cool air wherever you want in the room
- Slide-out filter offers easy access when cleaning is due
- Energy efficient operation – estimated yearly running cost is only $100
Cons:
- The wall sleeve is sold separately
- It gets very loud on the highest speed setting
A through-the-wall AC that is suited for spaces of up to 600 square feet since it outputs 12,000 BTUs, this Amana entry is definitely worth checking out if you’re looking for this specific setup. While far from perfect and not the cheapest, it makes up for its flaws quite effectively through its reliability, durability, and the fact that it is a versatile unit. What makes us say this? Well, it’s simple. Besides the standard Cool, Fan Only, and Energy Saver running modes that most ACs feature nowadays,
the Amana also integrates the Heat mode. Therefore, it’s a product that you can use year-round and that will help save on your bills when winter comes since it serves as a supplemental heating source.
It’s energy-efficient, which is important considering the generally high costs of running the AC through summer. But this isn’t the case here. Per year, it is estimated that it will cost you approximately $100 to enjoy the AC’s operation. On the downside, there are some extra costs that you must be aware of beforehand. For example, the wall sleeve isn’t included in the package, so you have to spend some extra cash. Other accessories that aren’t included are the thermostat and conversion kit.
It features 4-way adjustable airflow direction, the feature that you will likely benefit from the most since it lets you aim the cool air in whatever direction you like. Why have to move around the room when you can pick the spot where the cool air blows and sit there relaxed, right? It integrates a mesh filter that you have to routinely wash so that it can continue to effectively trap allergens and irritants lingering in the air that it cools. Don’t worry about having to keep a cleaning schedule though. The check filter indicator lights up when you have to wash the filter. Overall, it’s a product we and the plethora of happy customers recommend for its efficiency and performance.

9. Midea MAT10R1ZWT
Check Price at Amazon
Summary: Fairly priced considering the 10,000 BTU capacity and vast 450 square feet coverage this Midea product is one worth considering if you want to create pleasant conditions in your home when the torrid weather strikes. Since it’s a 3-in-1 unit that you can use as an AC, dehumidifier, or fan, it’s easy to see why this is a deal we recommend you carefully look into before you decide.
Pros:
- The 4-way automatic swing louvers move the air so that the whole room is cooled evenly
- Restarts with your most recent settings after a power loss occurs
- Sleep mode lets you set an hour for the AC to adjust its operation so that it creates pleasant sleeping conditions
- Check filter indicator shows you exactly when filter upkeep is due
- Remote control and installation accessories included with the package
Cons:
- The power cord could have been longer
- It tends to get a bit loud on the higher speed settings
This 3-in-1 unit from Midea is a perfect example of quality design considering the reliable performance it provides in the long run. We call it a 3-in-1 model since you can use it to cool the room, dehumidify, or opt to run the fan alone. Thus, whatever your demands are, the MAT10R1ZWT is guaranteed to comply with them. Since this is
a 10,000 BTU capacity model, you can count on it to keep the temperature at a bearable level during the hot months of the year in a space that measures up to 450 square feet in size.
Due to the 4-way air direction control, you can rest assured knowing that the room is evenly cooled since the louvers automatically swing to cover the whole area. It is rated at 55 dB, which isn’t supposed to be bothersome. However, on the high speed setting, people have reported that it’s quite tough to fall asleep with it in the room. But there is a solution – turn on the Sleep mode that adjusts the speed of the unit to create appropriate sleeping conditions.
The Midea boasts a 10.6 energy efficiency ratio, which is a good indicator of how energy-efficient this unit is. It features a washable filter that helps save money in the long run since you won’t have to routinely replace it. When the time comes to clean the filter, the indicator on the AC will let you know, making upkeep work more convenient.
A remote control is included with the package, so you can easily operate the AC across the room and adjust the setting to your liking. To install it, you must separately acquire the suited wall sleeve. Keep in mind that the AC measures 24.2 inches by 20.3 inches by 14.5 inches when you pick the wall sleeve to insert it into. Lastly, the manufacturer backs the product for 2 years for parts and labor, and 5 years for the sealed system.

Alternative Through-the-Wall ACs Worth Checking Out
We rounded up quite a few models to test for the writing of this article. All of our picks were based on expert opinion and customer feedback, making sure that we look into all potential contenders for the title. While the 9 products that we feature in the main ranking are, hands down, hard to top in terms of performance, there are a few other air conditioners that we think you might also like. So, if you don’t find the right product for you among our top picks, or you simply want to draw as many comparisons as possible before you decide, don’t jump into making a purchase before you also check out our alternative suggestions.
#1. Koldfront WTC8002WCO
Check Price at Amazon
A unit that is rated at
8,000 BTUs cooling power and that you should use in spaces of up to
350 square feet for optimal performance. When installed in an appropriately sized room, it will bring the indoor temperature to your desired setting in record time to ensure thermal comfort. You can customize the pace at which it cools the area by switching between the
3 fan settings. For added convenience, the package includes a remote control to lets you adjust comfort settings without getting up. Since it is
10.6 rated in terms of energy efficiency, you won’t spend much on operating this unit. In fact, the
yearly estimated energy cost is only $74. Another perk stands in the fact that it also works as a dehumidifier. Therefore, thanks to this versatile product, you can save considerable money since you won’t need a specialized dehumidification unit in the room where you install the AC.
Why we chose to leave it out: We tested two products from this brand and decided to include the Koldfront WTC14012WCO in our top instead of the WTC8002WCO for its higher cooling capacity and area coverage. This doesn’t reflect poorly on our alternative suggestion performance-wise, it just makes the WTC8002WCO the better option for those who need an AC to cool a smaller area.
#2. LG LT1430CNR
A powerhouse when it comes to cooling power since it produces
14,000 BTUs. Thanks to this high cooling capacity, you can count on it to perform optimally when used in spaces of up to
750 square feet. It does the job quicker than most ACs, which is why it’s one of the favorite cooling solutions of customers worldwide. It’s a flexible product in the sense that it features
3 cooling speeds and 3 fan speeds that you can pick from to tailor the unit’s operation to your exact demands. If you want a more hands-free operation, you can always use it in
Auto mode. When set on this running mode, it automatically switches between speeds to maintain your desired temperature while consuming as little power as possible. Speaking on, the
24-hour timer saves energy as it lets you schedule the AC’s operation to limit running costs.
Why we chose to leave it out: We favored the LG LT1037HNR over the LT1430CNR that we only left here as an alternative pick because our 3rd rank product can also provide heating. So, if you seek a year-round use product, the LT1037HNR is the better option. On the other hand, the LT1430CNR provides considerably higher cooling power, so it’s superior for regulating the temperature in larger spaces during hot weather. Decide between the two depending on what you specifically seek from the air conditioning unit you intend to acquire.
#3. Garrison 2477811
This Garrison unit is a prime example of how big of a difference the build of a product makes. Customer testimonies stand as proof of its durability, an aspect that we must praise since it implies that you are making a long-term investment. Since it produces
8,000 BTUs of cooling/heating power, it is an option best suited for areas of up to
350 square feet. And yes, you read that right, this model can also heat up the room. Hence, it’s a
year-round use air conditioner unlike most of the products we reviewed that only work for cooling. Aside from cooling and heating, it can run in 3 other modes that include
fan only, dehumidifier, and auto. When set in the Auto mode, it changes settings on its own to preserve your selected temperature in the most energy-efficient manner. Other features that add to its low power draw include the
24-hour programmable timer and the
Sleep mode function.
Why we chose to leave it out: We wanted to include only products that boast at least 10,000 BTUs of cooling power in our ranking, which is why this Garrison product was left out. This isn’t to say that the AC isn’t worth buying, it’s just better suited for smaller areas than what we wanted to cover with our main picks. So, if you have 350 square feet of space that you need cooling for, look no further since this is your ideal option.
#4. Emerson Quiet Kool EATC14RD2T
Built to provide rapid cooling in spaces of up to
700 square feet. This Emerson product is rated at
14,000 BTUs cooling power, hence its efficiency. Despite the considerable cooling performance, it manages to preserve low power draw. In fact, it is
Energy Star certified for how little energy it consumes to lower and uphold your preferred temperature indoors. You have
8-way flexibility when it comes to airflow direction control, so you can pick exactly where in the room and how the cooling breeze should hit. What we like a lot is that it is compatible with
wall sleeves ranging in width from 24.5 to 27 inches. It’s a smart, modern option that modern folks are bound to love since it can be controlled via multiple means. These include
the classic onboard controls, the remote control, the smartphone app, and voice controls. Another worthwhile feature stands in the
24-hour timer that you can program to have the unit running only when you need it to. In turn, this saves you a lot of money in the long run.
Why we chose to leave it out: It does the job more than fine, so rest assured knowing that it will stabilize indoor temperatures regardless of how hot it gets. However, we weren’t big fans of the noise it makes at the high running speeds, which is why we decided to only leave it as an alternative for similar cooling capacity models like the Whirlpool WHAT142-2AW and the Koldfront WTC14012WCO. These two models that feature in our top are quieter, so we deemed them as more deserving of your extra attention. Pick depending on what your budget allows and what model you prefer performance- and feature-wise.
#5. Keystone KSTAT14-2C
A
14,000 BTU cooling capacity unit from Keystone that works best when used in spaces no larger than
700 square feet. What we find most appealing is the product’s high energy efficiency. This
9.3 SEER air conditioner is estimated to
cost only $136 per year to run (
costs vary depending on your exact use of the product), which is considerably less than other products in its performance class. It fits
wall sleeves that measure from 24.5 to 27 inches in width. With the package, you receive a remote control for convenient operation. What this remote features in plus compared to other models is the
“Follow Me” function that ensures even room temperature since the remote features a thermostat. Thus, the AC takes notice of the room temperature where the remote is placed to make sure no corner is left unattended. We also want to mention that this unit is highly effective in terms of moisture removal. In fact, it eliminates the need for a dehumidifier in the room where you set up the AC since it can
remove up to 2.9 pints of moisture per hour.
Why we chose to leave it out: Although the KSTAT14-2C scores higher in terms of cooling performance than the Keystone KSTAT10-2C that we ranked 6th, it features as an alternative instead of an entry in our top because our tests showed that the 10,000 BTU model is much faster. However, in all fairness, the KSTAT14-2C is suited for larger areas, so it’s bound to be slightly slower. Pick between the two depending on what area coverage you need the AC to provide.

Frequently Asked Questions
Will I need a sleeve?
Yes. All through-the-wall models need to have a sleeve for installation, support, and hassle-free maintenance. While many models nowadays come equipped with one, check and see if the model you wish to acquire includes one. If it doesn’t, you must separately acquire it.
How can I seal around it?
To keep pests from entering, the best way to seal around an in-wall air conditioning unit is to use a caulk. Acrylic caulk is the easiest to apply and it seals even the smallest holes in the wall. While it is the most durable type of seal, it does shrink with time, so make sure that you don’t plan on using it for a large area.
Can it cool my entire house?
No. Each unit is specifically made to lower the temperature within the room where it’s installed, based on its area coverage. If you want to cool all the rooms in your home, then you should install ACs in other areas of the house too.
Can it also heat?
Some ACs can produce both hot and cold air, while others are limited only to lowering the temperature in the room they’re set up in. Check the spec sheet to see what type of unit you’re dealing with before you buy if you want an AC that is good for use year-round like the Frigidaire FFRH1822R2.
Why are through-the-wall ACs more expensive?
The initial cost for a wall AC is not necessarily bigger when compared to that of a window AC, for example. However, the difference is made when it comes to installation costs seeing how you need to cut a hole in the wall to set up this type of air conditioning unit. Setting it up is more challenging and time-consuming seeing how you must avoid wires and pipes in the wall where you cut the hole for the AC, and that you must create a perfectly sized space for it. This is why most homeowners who choose a wall AC directly opt for professional installation, which raises costs even more.
What is the difference between window and wall air conditioners?
The main difference between window and wall AC units stands in their installation location. As implied by their name, window units are installed on a window sill, while wall units are placed on an exterior wall.
How much does it cost to install an AC in the wall?
If you opt for professional installation, the total cost for the installation should be approximately $730, whereas if you opt for DIY installation it will cost about $540. Beware that you have to cut a hole in the wall, which isn’t easy at all and it is a pretentious task too seeing how you must make sure that you don’t cut through a spot where the pipe runs or where there are wires. While it is more expensive, a professional installation is the better option of the two.
Conclusion
When the torrid weather makes its inevitable appearance, feeling comfortable when you’re at home is off the table without the help of an air conditioning unit that lowers the internal temperature. Sitting in a hot environment isn’t only uncomfortable but it poses a health issue too since you can fall victim to a heat stroke, so the presence of an AC unit can become compulsory, especially if you live in an area where temperatures go haywire during the hot season. If you are interested in a permanent solution to adjust the temperature indoors and create comfortable living conditions, and you don’t want to sacrifice floor space or have a window become unusable either, then a wall AC is your best solution. We already reviewed and ranked what we found to be the best through-the-wall air conditioners, but before we end we want to go over a few of the standout models once more to help you make up your mind easier.
