Consumer Reviews Analyzed

T hrough the wall air conditioners are permanent solutions for cooling the air in a room, and they come with multiple advantages. Unlike window models, which block the view, they go directly into the wall through a wall sleeve, so they save space in the room and keep the window clear. The front side is oriented towards the interior of the room, while the rear side goes on the exterior of the wall, blowing the heat generated by the motor outside, so the temperature in the room isn’t affected. Thus, the effort of maintaining a pleasant, cool environment indoors is reduced, and the energy-efficiency increased.

At first glance, it may seem easy to pick a model by looking at its dimensions, capacity, and price. But these units have plenty to offer. They come with smart functions, modes, and some of them even feature a heat function for the cold season, so it would be a pity not to consider all of them before making the purchase.

Our article includes a complete list of specifications, a detailed review, pros, cons, and an honest verdict for each of the analyzed models. So, stay with us as we go through 8 of the best through the wall air conditioners on the market to find out which model suits you best.

8. Koldfront WTC8002WCO 8,000 BTU 115V – Best for Small Rooms

Specifications:


  • Area Coverage: 350 sq. Ft.
  • Cooling Capacity: 8,000 BTUs
  • Supplemental Heating Option:
  • Fan Speeds: 3
  • Dimensions: 20.4 x 24.2 x 14.5 in.
  • Dehumidification Function:
  • Airflow: 270 CFM
  • Noise Level: High: 56.8 dB/Med: 53.7 dB/Low: 51.8 dB
  • Wattage: 754

  • Energy Efficiency Ratio: 10.6
  • Timer:24-hour
  • Controls: Push Buttons
  • Filter: Washable air filter
  • Energy Star Certified:
  • Auto Mode:

  • Sleep Mode:
  • Warranty: 2-year limited, 2-year parts


With a cooling capacity of 8,000 BTUs, it was designed to deliver a good airflow for spaces of up to 350 sq ft. It is more compact than other models, with a depth of only 20 inches, a width of 24.2 inches, and a height 14.5 inches, so it requires a smaller hole in the wall. The installation is easy and implies the mounting of a WTCSLV wall sleeve that will seal the space between the hole’s limits and the housing to prevent the outdoor air from entering the room. As the rear side is facing the exterior, the heat produced by the motor won’t be released inside the room, and thus it won’t affect the temperature. It has a peak airflow of 270 CFM, which is lower than what other models have to offer, but perfect for the recommended space. Furthermore, the noise peaks at 56 decibels, but it proves to be fairly quiet at the lowest speed, where it reaches only 51 dB.

The controls are placed on the front side and offer access to a multitude of functions. First of all, it allows you to adjust the fan velocity by selecting either the High, Medium or Low setting. Secondly, if you don’t wish to constantly check the temperature and adjust the fan manually, you can activate the Auto setting, which will take care of this for you. A fan mode is available if you want it to circulate the air without cooling it. This option is perfect for quick ventilation during the winter when the temperatures are too low to allow you to keep the windows open for long. During the night, you can activate the Sleep mode, which will gradually increase fan speed to ensure a comfortable ambiance without producing a lot of noise. Plus, this function will reduce energy waste as well.

It has an energy-efficiency rate of 10.6 and a peak power consumption rate of 754W, so the costs it will generate are reduced. Moreover, you can save even more money if you set the timer, which will automatically turn it off when the selected time has passed. It includes an auto-restart function that will prove helpful in case the power supply is closed by a storm or other malfunctions, as it will save the last settings and reinstate them when the power is back on. Furthermore, if you are struggling with high humidity, it is good to know that it comes with a dehumidification setting and can draw up to 1.8 pt of moisture/hr.

All the functions can be activated from distance through the remote control that arrives in the package. It is easy to maintain, as you will only need to clean the filter once in a while. Additionally, in case a malfunction or a mishap shall occur, you can call the manufacturer for repairs, as this model comes with a 2-year warranty that covers both parts and labor.

What we like:
  • Low power consumption
  • Compact design makes it easy to install
  • Smart modes and remote control increase convenience
  • Dehumidification function
  • Backed by a generous 2-year warranty
What we dislike:

✖ Designed only for small spaces

✖ The dehumidification capacity is rather low

Verdict

For the price, it surely has plenty to offer, so if you are on a budget and looking for a unit that can cover a small space, you should go with it. The EER is excellent, so the overall running costs will be reduced. Besides that, it is highly-customizable, as it offers an Auto and a Sleep mode, and 3 speed settings, so you can adjust the operations to your taste.


7. Keystone KSTAT08-1C 8000 BTU 115V – Best Energy Efficient

Check Price at Amazon


Specifications:


  • Area Coverage: 350 sq. Ft.
  • Cooling Capacity: 8,000 BTUs
  • Supplemental Heating Option:
  • Fan Speeds: 3
  • Dimensions: 24.2 x 20.3 x 14.5 in.
  • Dehumidification Function:
  • Airflow: N/A
  • Noise Level: High: 56.8 dB/Low: 51.8 dB
  • Wattage: 754

  • Energy Efficiency Ratio: 10.6

  • Filter: Washable air filter
  • Energy Star Certified:
  • Auto Mode:
  • Auto Restart:
  • Sleep Mode:
  • Warranty: 1-year limited, 1-year parts


Although it is a compact unit that will easily fit in a smaller wall hole, it is extremely powerful, as long as you use it in the recommended space, which shouldn’t overcome 350 square feet. Its cooling capacity reaches 8,000 BTUs, so you should expect pleasant waves of cold air. Nevertheless, what makes it even more attractive is its excellent 10.6 energy-efficient rate. With a consumption rate of only 754W, it consumes at least 15% less than a conventional air conditioner, therefore it meets the conditions for the Energy Star certification. Furthermore, it offers a dehumidification option, being able to draw up to 2.1 pt/hr of water and a total of 50 pt/24 hr, so if you live in a humid area, you won’t even need a dehumidifier to maintain humidity under control.

It measures 24.2 inches in width, 20.3 inches in depth, and only 14.5 inches in height, so it will fit in a regular 24. 5 to 27 inches sleeve. If you are not replacing an old unit and, therefore don’t own the sleeve, you will need to purchase it separately. However, if you do own it, the good news is that Keystone will provide you with an installation kit and the foam required to thoroughly seal the remaining space, all for free. Besides that, maintenance won’t give you any troubles, as it is fairly independent and only requires you to periodically wash the air filter so it can keep performing at the optimal level.

The control panel includes an LCD that will display temperature. The control keys are placed around the display and provide easy access to modes and functions. Here you will find the Auto mode, which allows for easy observing of the temperature and automatic fan speed adjustment, and an Energy-saver mode that can be used through the night to moderate power consumption. The remote control has a built-in thermostat that allows you to monitor temperature from distance and manually adjust the fan speed by choosing one of the 3 options. Depending on your selection, the noise level will variate between 51.8 and 56.8 decibels, which are decent values for an air conditioner.

It comes with a timer and integrates an auto-restart function, so it is easy to control. However, it lacks a heating function that would have provided a comfortable atmosphere during the spring or autumn in days with lower temperatures. Additionally, the 1-year warranty is rather short compared with other models, but at least it covers both parts and labor.

What we like:
  • Excellent energy-efficiency rate
  • Comes with installation kit and sealing foam
  • High dehumidification rate
  • Remote control includes a smart sensor that allows you to monitor the temperature from distance
  • Auto-restart function
What we dislike:

✖ Short warranty

Verdict

Comfort costs, but the real question here is how much. You shouldn’t have to spend every penny in your pocket to keep your bedroom or living room cool during the summer, and this is what the engineers at Keystone probably had in mind when designing this model. It is not only energy-effective, but it comes at an excellent price and offers the complete smart mode package, so it is worth considering, but only if you are planning on using it in a small room.

It shines through its solid construction and painted gold fin coating that makes it super resistant to corrosion and rust. It is an excellent long-term investment for medium rooms with a surface of up to 440 square feet. As it measures only 14.4 inches in height, 24 inches in width, and 20.1 inches in depth, it is rather compact and will fit into a 24.5 to 27 inches wide wall sleeve. If you are not replacing an old unit and don’t own the sleeve, the manufacturer recommends the AXSVA1 or AXSVA4 model, which needs to be purchased separately, as it is not included in the package. You can make the installation yourself, as the manual is straightforward, but only if you possess the necessary knowledge and practical skills. Otherwise, you risk voiding the 1-year warranty, so if you are a profane to these types of setups, it is better to call for a specialist.

It comes with user-friendly controls and a remote control. The push buttons are placed on the left corner of the unit and include POWER, FAN SPEED, TIMER, and MODE. By pushing the speed button multiple times, you can alter its current airflow and noise level. The maximum CFM it can reach is 250, a great value for the space it needs to cover. Additionally, the sound will variate from 53 dB at the lowest setting to a peak of 56 dB when the highest setting is reached. Above the power button, you will find two buttons for temperature setting and an LCD screen that will display your selection. You can set the air conditioner to run on Auto mode, and it will automatically adjust the fan speed to reach the selected temperature. It features a Sleep mode as well, which will gradually increase the airflow through the night so you can enjoy a pleasant atmosphere in the morning. Furthermore, with an auto-restart function included, you will be backed if a power outage occurs through the night, you won’t wake up all sweaty in the morning, as it will restart on the spot when the power is back on.

The energy-efficiency rate is 10.6, so the costs are rather reduced compared with other units. Moreover, as it includes a dehumidification mode and is able to draw up to 3.2 pints of moisture per hour, you won’t need to invest in a dehumidifier, as it can handle even extremely humid areas. Additionally, the fan mode will help you circulate and freshen up the air in the room without cooling it, so it will prove helpful through the winter when you will be able to perform optimal ventilation without opening the windows.

What we like:
  • Strong gold-fin coated construction is resistant against corrosion
  • Adjustable speed and automatic modes make it highly-customizable
  • Auto-restart function
  • High dehumidification rate
  • Energy Star certified
What we dislike:

✖ Some customers complained that it is loud

Verdict

Perfect for medium-size rooms, it can provide a strong airflow to cover up to 440 square feet, all while maintaining the energy consumption within decent limits. It comes with a remote that allows for easy control from the distance and includes 4 fan modes, designed to cover every user’s needs.

It is a multifunctional model that can run all year round, providing excellent cooling during the summer and a pleasant warmth during spring, autumn, and winter. The main cool setting can deliver up to 12,000 BTUs, enough to cover a room as large as 550 sq ft, while the heat mode can release up to 10,600 BTUs of warmth, creating a comfortable temperature in spaces measuring up to 450 sq ft. The switch between the functions can be made by turning on or off the heat function on the control panel. Moreover, as it features a dehumidification function with a moisture removal rate of up to 60 pt/day, it can compete with the strongest dehumidifiers and is suitable for humid spaces where it can quickly remove the water excess in the air.

With a height of 14.5 inches, a width of 24.2 inches, and a depth of 20.4 inches, it can be placed among the most compact models in the industry. The installation requires some practical skills or the hand of an expert, but you will be done with it pretty fast. You will have to purchase the sleeve though, as it isn’t included in the package. The manufacturer recommends a WTCSLV model.

Regarding usability, we must admit that it offers everything you need for complete customization. You get to choose among 3 fan speeds, with the highest being able to generate a great airflow of 286 CFM. It comes with an accurate humidistat that monitors the temperature and shows it on the digital display. The Auto mode uses the data to automatically select the most appropriate fan speed.

Furthermore, you can use the Fan mode for quick air circulation, as it was designed to ventilate the rooms without altering the temperature.

The 9.5 energy-efficiency rate may seem low, but we must consider that it is affected by the heat function, which requires more energy than the cooling function. The peak power consumption rate reaches 3,450 watts on Heat and 1,330 watts on Cool, values that were considered too high for it to receive an Energy Star certification. Nevertheless, it comes with a 24-hour timer so you can use it to control running time and reduce energy waste.

What we like:
  • Offers both a cooling and a heating option
  • High cooling capacity
  • Powerful dehumidification
  • Accurate thermostat
  • Generous 2-year warranty
What we dislike:

✖ The power consumption is rather high

✖ Some customers complained that it is loud

Verdict

It is a popular model, often picked by buyers for its double function and great price. It is produced by a renowned brand, which offers a 2-year warranty, so you can rest assured that any flow or mishap will be handled fast and without supplementary costs from your part. Moreover, it has an exceptional moisture removal capacity, so it can be used as a dehumidifier as well.

Furthermore, with an airflow of 286 CFM, it can easily cover a room with a surface of up to 550 sq ft, so it is suitable for medium-sized spaces. It can maintain the temperature between 62 and 86 degrees Fahrenheit and comes with a performant dehumidification mode that can remove up to 60 pt/day of water.

The design is practical, with the control panel being placed at hand on the front. The electronic keys are wisely labeled, so you will easily find your way with them. Like in all Koldfront units, speed selection is possible, and you will only have to press the speed key until Low, Medium, or High is displayed on the digital screen. Moreover, you can set the desired temperature and let the Auto handle everything.

Additionally, this model offers the Fan mode for efficient air circulation without cooling.

Just like most Koldfront units, it measures 14.5 inches in height, 24.2 inches in width, and 20.4 inches in depth and is compatible with a WTCSLV wall sleeve.

A split model that is highly popular among customers, it comes with cooling and heating functions and is one of the quietest on the market. It can cover medium-sized rooms with a surface of up to 450 square feet and features a great airflow of 247 CFM at the highest speed, 182 CFM at medium speed, and 129 CFM at the lowest setting. The cooling capacity is as high as 9,000 BTUs, which is perfect for small rooms and just the right amount for the recommended space. Nonetheless, during the winter, it can provide up to 10,000 BTUs of heat, and can function as an additional heating source.

With an energy-efficiency rate of only 10, it is not an energy-effective model and hasn’t been Energy Star certified. In fact, the power consumption reaches 925 watts, so it will cost you. Let’s see then why you should invest in it. First of all, it is accompanied by a 5-year warranty, which is higher than the coverage provided by renowned brands. Secondly, it has superior-quality construction, designed to resist over time without developing rust and corrosion. The smart modes allow it to function as a dehumidifier and fan as well. Last but not least, it is extremely silent, with a sound level that peaks at 38 decibels and only reaches 25 decibels at the lowest airflow. Therefore, it is an excellent pick for a bedroom or kids’ room, as it is unnoticeable. This is truly a surprising feature as such a low level of sound is only produced by small air purifiers of humidifiers.

It comes with a full installation kit, and the manufacturer recommends professional installation. As it is a split system, you will need to deal with 2 units, one that goes on the interior and the other on the exterior. The inside part of the system measures 28.43″ in width, 7.36″ in height, and 11.42″ in depth. It is rather bulky, but once you find a good place for it, it won’t be in your way. It comes with a remote that offers access to functions like a 24-hour timer, Auto mode, Sleep mode, Fan mode, or Self-Clean. Moreover, you can adjust fan speed and check the temperature on the LCD screen situated on the top of the remote.

It can work in extreme temperature conditions with a range of 5 to 122 degrees F for the cooling function and 5 to 86 degrees F for the heating function. Furthermore, it includes the auto-restart mode, so it is able to save the last settings in case of a power outage and restore them when it is powered again.

What we like:
  • Dual function makes it suitable for all-year-round use
  • Complete installation kit
  • Strong construction
  • Super quiet
  • Generous 5-year warranty
What we dislike:

✖ High energy consumption

Verdict

It is perfect for bedrooms, as it is one of the quietest on the market. It is sleek and offers both cooling and heating, so you can use it all year round to keep your room comfortable.

It is super versatile, as it was built to fit both a window and a wall. It has a simple design and is fairly compact, with a height of 15″, a width of 23.6″, and a depth of 22.2″. The wall sleeve is built-in, so you will not have to pay any extra money. In fact, it comes with a complete installation kit. If you decide for a window installation, you should make sure your window has a width of 25.25″ to 39″. The maximum extension into the room can reach 4.5 inches, while the unit can extend outside with a maximum of 12 inches. For the through-the-wall installation, you will need to cut a hole in the wall with a height of 15.25″, a width of 23.875″, and a depth of 8″.

It offers a cooling function only, but we must admit that the airflow is outstanding, reaching up to 330 CFM. It has a cooling capacity of 12,000 BTUs and can cover medium-size rooms measuring up to 550 square feet. Besides that, it is energy efficient, with an energy efficiency rate of 12.1 and a maximum power consumption rate of 1,100 watts.

The Auto mode increases and lowers the speed according to the temperature in the room, so, by setting it, you can make sure you get the maximum efficiency. Moreover, it comes with a 24-hour timer for run-time customization and an auto-restart function for emergencies.

It lacks a Sleep mode, but it compensates through some amazing design features like a trademark slide-out chassis, which makes it easy to slide out for periodical cleaning, commercial-grade side curtains that prevent noise and light from entering the room, and anti-microbial filters. Moreover, the dehumidification function is highly-performant, with a moisture removal capacity of up to 70.2 pints per day. The louvers swing automatically to adjust the airflow from right to left for a boost of cool air. Besides all that, it comes with a 1-year warranty for the parts and a 5-year warranty for the compressor, so you will be covered no matter what flow you discover.

What we like:
  • Two installation methods
  • Superior construction makes it durable and easy to clean
  • Commercial-grade curtains provide excellent isolation
  • Auto Mode
  • Outstanding dehumidification capacity
What we dislike:

✖ Lacks a Sleep mode

Verdict

Our runner-up and favorite for its high-quality construction and clean design, it would make an excellent choice for any medium-size room. It is compact and can be installed either in a window or into the wall. Furthermore, at 12,000 BTUs it can face even the hottest days, ensuring a comfortable atmosphere for users living in dry and hot areas.

The maintenance is easy, as it comes with a washable filter that only needs to be cleaned once in a while. Furthermore, it features a low-power startup that reduces energy consumption.

Versatility at its Best

It is an expensive unit, so there’s no wonder that apart from the superior cooling capacity it offers smart functions and extra features. The compact design makes it an excellent fit for every room, and the installation is fairly easy, especially as it comes with a complete installation. Nevertheless, the following features make it stand out among its competitors:

  • Cooling/Heating function – allows it to run all year round, even when temperatures go as low as 45 degrees Fahrenheit

  • Additional dehumidification function – it can remove up to 132 pints of moisture per day

Important to mention, this unit will only work with a special 230V electrical outlet, so you will need a transformer.

The 8-way comfort control design allows you to direct the air all over the room, an operation that can be performed manually or automatically. Furthermore, the strong construction is doubled by excellent capabilities such as:

  • Large area coverage – up to 1,050 square feet
  • High cooling and heating capacity – 18,500 BTUs for cooling and up to 16,000 BTUs for heating
  • Excellent airflow – 446 CFM at the highest speed, 388 CFM at medium speed, and 329 CFM at the lowest speed

By adjusting the fan speed, you can either lower or increase the noise level, which can variate between 54 and 60 decibels. Although it is a bit louder, the lower speed manages to maintain a reduced noise level, so you can use it for your peaceful moments. Additionally, we should mention that this unit has a high power consumption that reaches 1,650W on cool and 4,900 watts on heat, so it will show up on your power bill. Nevertheless, the EER is 10.7, which shows it is still an energy-efficient unit when we take into account the report between its capacity and energy consumption.

User-Friendly Controls

It comes with electronic controls that are placed on the front side. We liked that they are well-labeled and user-friendly. A remote is included as well, and it will allow you to control fan speed, set the mode, the timer, and check the temperature on the LCD screen. It features 4 modes, namely Sleep mode, Fan mode, Auto mode, and Energy-saver mode, each of them designed to cover specific situations and increase the air conditioner’s efficiency. Plus, it comes with an auto-restart function as well, and it is covered by a 5-year warranty for the sealed system and 1 year for the parts id the system isn’t sealed anymore.

  • Offers 2 installation methods
  • High area coverage
  • Cooling and heating function
  • Window installation kit included
  • Easy maintenance due to the slide-out chassis
  • Smart functions and modes
What we dislike:

It is the best you can get at the moment: outstanding capacity, superior-quality construction, and a wide range of smart functions. It is compatible both with wall and window installation and offers a cooling and a heating function as well. Besides that, maintenance is easy, as it comes with a slide-out chassis that allows you to easily remove it for filter cleaning.
