11 Best Rated Small Portable Air Conditioner – Cool Small Rooms

W hen summer comes, dealing with the heat can be tricky if you live in a small apartment or work in small-sized offices. Cool air blowers are life-saving during torrid days, but limited installation space might be a challenge for the bulky models. Luckily, portable air conditioners have been designed so limited-space rooms can easily be cooled without drilling holes in the walls or purchasing large units.

These devices need to be mounted on a window and they come with a full installation kit, and the best part is that they can be transferred to another window when necessary and you can even change their spot in the room due to the telescopic discharge hose. Hence, you will enjoy versatility and handiness, along with excellent cooling abilities. Without further ado, take a closer look at the most wanted models that can be fitted in any home.

If you want a permanent air cooling system that can be easily mounted on a sill, you should address vertical window ACs as their installation is less complicated and they can also be moved at choice, thus representing a more versatile option to wall-mounted models.

Given we live in the era of technology, it’s expected to find increasingly more appliances that can be hooked to the internet so they will provide distance control. This is the case of this groundbreaking AC designed by Frigidaire that can be connected to an internet network.

Innovation

If you like your appliances smart, you will love this one that offers internet connectivity so you can easily have control over it using the personalized app. As such, you can observe its status, make temperature selections, or set it to start before you get home from work, so you will be welcomed by a comfortable ambiance. In case you don’t want to pair it with the app, you can still control it with the included remote or by pressing the keys on its top side.

Appealing design

Many people want to match their appliances to their home décor, so the overall result will be pleasant. This interesting piece of equipment will surely blend seamlessly into a modern home due to the uncommon design. It’s tall, measuring 36.81” high, but it’s extremely narrow at 12.63”, something you will appreciate if you want to keep it out of sight. The shape is not the regular rectangular you would see in most ACs, it’s more circular, resembling a tower. The clean lines, the round fan outlet, and the elegant LCD with LED lighting on the front promote it as a very luxurious appliance.

Cooling Abilities

Aside from looking good, this device also provides the highest results in cooling indoor spaces. First of all, we must mention that it needs to be installed near a window so the discharge hose will connect to the exterior. For this, you will get an installation kit in the package, with all the essential pieces you need for mounting it on any type of window that slides either vertically or horizontally.

The cooling capability exceeds the average of these small portable units, reaching 550 sq. ft., all due to the amplified BTU of 12,000. This will only lead to faster and more effective outcomes despite your location. The silent functionality is another trait to have in mind, as you can place it anywhere, even into an office, without disturbing you with unpleasant sounds. It releases 53 dB on the lowest fan speed. Speaking of, you have three cooling and three fan velocities to personalize the surrounding temperature as you like best. The cylinder shape contributes to its cooling performance, as the airflow circulates 360-degree in an upwards, continuous spiral ensuring it gets into every corner of your room faster. The timer can be set up to 24 hours, enabling the AC to turn on and off after it has reached the chosen temperature or once the time runs out, so you can safely program it to work while you are not at home.

Besides the Auto and Cool modes, an Eco mode is added to help you save on your electricity bill. This mode turns off the machinery once the desired temperature has been reached, so it will not waste energy. Also to preserve energy, the Sleep mode can be selected during the night, ensuring the proper resting ambiance while limiting the electricity consumption. Plus, the AC also works as a dehumidifier, a very powerful one that can take out around 3 pints of dampness from the air every hour. During this process, the air is passed through 4 filters, positioned at the back, so fewer allergens and impurities will be left behind. This filtering ability promotes it as a highly helpful device for people suffering from allergies or for babies who need to live in a very clean environment. To minimize your expenses, the filters can be washed then reattached to the unit. You will know when it’s time for this when the alert button will light up.

Also for peace of mind and as protection for your investment, the company ensures the unit for 1 year and the sealed component for 4 years.

Compare these portable units with the larger versions that are wall-addressed and see which one matches your requests. Our selection of through-the-wall ACs includes the most wanted models available in stores.

It has caster wheels so you can move it wherever the exhaust tube can reach, so it can target the areas that require specific cooling.

Don’t think that all it does is cool the air, as it can function as a multi-use device with three functions: air conditioner, fan-only in case you want to reduce the energy costs, and dehumidifier for humid areas where the heat feeling is accentuated by the moisture in the air.

When set as a fan, it circulates up to 170 CFM, so the cold air current will be easily noticeable.

It has directional louvers that move so the cold air will be sent into every corner of the room and you can set it to blow at three different intensities.

To make good use of it, you must install it on a sill so it will communicate with the exterior. The included elements let you set it on any sill measuring from 29” to 38” wide. To make sure the cool air reaches where it is needed the most, the AC comes with caster wheels and an exhaust hose extendable up to 49”, so you can easily relocate it around the room without having to take down the window mount. However, anytime you want to move or store it, the kit easily disassembles and you can do this yourself. You must never skip mounting the kit on the window as it also doubles as a dehumidifier, allowing the AC to collect up to 50 pints of moisture per day. All the liquid evaporates so you won’t have to drain it manually. A washable filter helps it clean the air as it drains the moisture out, fully increasing the comfort level in your house.

The setup is similar to the other models, as it offers an AC, a dehumidifier, and a fan-only mode, giving you the option to select the one that is suitable for your house.

  • Noise Level: 51 dB
  • Highlights: Swinging air discharge chute
  • Window Bracket: 18” to 50”
  • Exhaust Hose: 5” diameter; max 72” long
  • Warranty: 1 year


We continue our list with another smart AC designed by LG, so it should come as no surprise that it’s such a popular choice among customers. While not as potent as the previous, it remains a trustworthy choice due to the forward-thinking technologies it embraces. It’s another model that can be controlled via the internet due to the LG app that can be installed directly on your smartphone.

For starters, know that it can be installed on any window using the included kit that contains a bracket that extends from 18” to 50”, making it greatly versatile. The housing measures 12.8” deep, 16.9” wide, and 27.3” tall, so it’s a medium-size unit that shouldn’t be hard to accommodate. You can effortlessly move it due to the caster wheels. The 8,000 BTU it outputs makes it strong enough to handle areas up to 200 sq. ft. but don’t let this make you think it will not be helpful on hot summer days. Due to the oscillating air discharge that swings up and down, the cool air will travel around the entire room, for extended coverage and fast results. If you don’t wish to use this feature, you can simply set the air discharge to remain fixed by pressing the key on the remote.

As we mentioned above, this AC can be accessed through an internet connection, but this is not the only smart feature it involves. The Auto Restart enables it to retake the cooling process from where it was left, in the event of a power shortage. Also, it includes a timer that lets you personalize its functioning schedule. It’s very silent, releasing only 51 dB on the lowest of the two speeds, so it can even be located in the bedroom. For nighttime, you can choose the Sleep mode and it will maximize the cooling results while minimizing the energy usage by turning off when the temperature has decreased by 1 degree.

It also provides the reimbursements of a dehumidifier and without any sort of upkeep involved, thanks to the self-evaporation mechanism that vaporizes the moisture created inside the unit so you won’t have to constantly empty a bucket. It also acts as a part-time air purifier due to the incorporated back filter that can be washed also for reasons of limited upkeep. In terms of the warranty, we would have expected more from LG, but the product is warranted only for 1 year.

PROS

  • Limited power usage
  • Automatic oscillation leads to even airflow
  • The extracted moisture evaporates inside the unit
  • Smart internet connectivity
  • Auto Restart function

CONS

  • The warranty is shorter than expected
  • There is no Eco mode available


VERDICT

This is one of the most reliable compact ACs that can be easily moved around the house thanks to the small dimensions. It might not have the biggest BTU output but it manages to cover every inch due to the swinging air discharge. Not to mention the smart connectivity that makes it ideal for people who want their appliances to be intelligent and remotely accessible.

A remote is also added for more user-friendliness. The device also works as a dehumidifier and it can collect around 44 pints of water in one day, thus helping you make the ambiance more pleasant by reducing the air humidity. Draining is effortless, as it drains by itself, so you won’t have to frequently discharge the water. It also includes a hose in case you want to go for the continuous drain mode.

Other features worth revealing are the auto restart, the programmable timer, and the Sleep function meant to limit energy usage without sacrificing cooling performance. It has not one, but two filters intended to retain airborne impurities, and there is no need to frequently buy replacements as you can conveniently wash them. An LED will alert you when it’s time you check on the filters.

Care & Maintenance


Compact ACs need proper upkeep to provide you with a long lifespan and optimum performance. Usually, they have a hassle-free operation, and maintenance should be the same, too. As it is already known, these units need to be installed through a window by using an installation bracket and an exhaust tube. Though, they necessitate less maintenance than other types of cooling systems. To ensure you do it right, consider the following aspects:

  • Placement: As previously mentioned, you must install these ACs near windows because they must take air from the exterior. More important, it should be a clean area, where no dirt can get into the fan and cause damage. Take note that it’s impossible to install them in basements, crawls spaces, or rooms that don’t have a window. Also, make sure there is a power outlet nearby, so the cord will reach it.
  • Power Analysis : As it concerns the power, make sure that the electrical grid will furnish 120V, at minimum 15A. In this way, the compressor and fan motors will have enough power to properly function. You can utilize an electrical surge preventer to avoid unwanted damage to the unit in case of a power surge.
  • Drainage: Installing the exhaust tube needs a little precision, too. Avoid extending the hose to the maximum length or bending it in any way. Otherwise, the humidity from condensing might rotate back into the unit, causing damage.
  • Filter Care: Regular filter cleaning will assure it a long life. All the mesh filters on portable ACs are washable, so all you have to do to avoid dust and dirt build-up on the coil is to give the filters a rinse in water. Note that you do should not use soap or detergents during the cleaning process as they leave a sticky coating on the filter, leading to clogging. For best results, filters need washing every 3-6 months.
  • Storage: When the summer season is over, the unit needs to be drained to eliminate all the accumulated water. Next, ensure to run it in the fan mode at high speed. Do this for three or four hours so that it gets completely dried. Then, put it into a protective cover and store it in a place where there’s no humidity.
