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 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.

Portable ACs do need to be vented out a window or, as we will immediately explain, using other ingenious methods. Likely their biggest advantage, what makes them more appealing than their wall or window counterparts, stands in their portability. Moving the AC from one room to another or relocating it to the same room isn’t a problem anymore. Hence, you will enjoy versatility and handiness along with excellent cooling abilities. Without further ado, take a closer look at the most wanted models available at the moment.

How to Vent a Portable Air Conditioner without a Window

Say that you want to use the AC in a room that simply lacks windows, or you don’t have the possibility to vent the hot air it produces in this manner for any other reason. What do you do in this situation? Is using a portable AC off the table because of this detail? Ventilation is the issue that rules out portable ACs for a lot of people, but it doesn’t necessarily have to be. You just have to get a little bit creative, and you can find a solution to use the portable AC even in a room with no windows. These are the common fixes to this issue:

  • Venting the AC through a wall: While an effective solution, it can be tricky if you don’t do your math right before the setup since you have to drill an actual hole through the wall. So, make sure that you know beforehand the right diameter the hole you drill must have so that the AC’s hose pipe goes through without drilling it larger than necessary. After you drill the hole, make sure that you seal it with silicone caulk so that environmental irritants won’t come through. Cut the tip of the hose at a 45-degree angle and apply caulk around it on the wall.
  • Venting the AC through a door: Door ventilation isn’t always an option, unfortunately. Say that you have a usable room on the other side of that door, like your home office or living room. You won’t be able to vent through it because the hot air produced by the AC would go into that particular living space and only make things worse. If the door leads to the entrance hallway, for example, it is a perfect solution to exhaust the hot air. Those who have pets can use the cat/dog door to pass the hose through when their furry friends are already inside and their special door isn’t used. The easiest way to vent through the door is if the door is a sliding type. There are special kits for this setup, and you can directly vent the AC outdoors this way.
  • Venting the AC through the chimney: This is, by far, one of the easiest ways to get rid of the hot air. If you have a chimney in the windowless room where you plan on setting up the AC, and you’re not using it at that specific time of the year, pipe the exhaust hose through the chimney, and the hot air is automatically expelled to the exterior.
  • Venting the AC through the ceiling: If your home has a drop ceiling, you can consider venting through it too. Just make sure that you don’t interfere with the pipes and electric wires that run on top of the ceiling panel when you drill the hole in the ceiling. After you drill the hole, run the hose through it, and make sure that you tightly seal any openings with silicone caulk. If you do choose this setup, you must also routinely check the humidity level in the ceiling space to regulate it if needed and make sure that mold won’t grow there.

*You might have read or heard that you can vent the AC through a dryer vent. While possible, this procedure is not recommended by manufacturing companies or HVAC experts since you might have to force insert the AC hose into the dryer vent, for one. Then, there’s the issue that you will have to constantly monitor both the AC and the dryer to make sure there are no efficiency-related issues down the road because of this specific setup.

If you want an air cooling system that can be easily mounted on a sill, you should look into vertical window ACs.

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 its 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. If, however, you need an AC that can handle a space that’s a bit larger, the Della 048-GM-48384 is the right alternative since it’s recommended for areas of up to 700 square feet. The silent functionality is another trait to have in mind, as you can place it anywhere, even in 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 degrees 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 electricity consumption.

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 and then reattached to the unit. You will know when it’s time for this when the alert button will light up. Furthermore, 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.

If you want an air cooling system that is completely out of the way, you might be better off with a through-the-wall air conditioner. The cooling performance is basically the same; the difference between these systems stands in how they install.

Performance Test Feedback

As expected with any portable air conditioner, setting it up was a cinch. I like the design because it reminds me of an air purifier more than an AC, so this Frigidaire unit is quite distinguishable from the rest of its competitors. During testing, what I noticed and really liked is how silent it stays on any of the 3 running speeds it can be set on. It’s quite rapid when it comes to cooling the room, which I appreciated since this is the most important stat with any air conditioner, after all. What you likely won’t be a fan of, however, since neither was I, is that the AC is a bit difficult to relocate. It’s heavy, so you might not like how much work you have to put into pushing it around. When it comes to moisture accumulation, I had to empty the bucket after almost 2 weeks. This might not be the case for everyone, it depends on how humid the area you live in generally is, and on the time of the year when you use the AC. Overall, it’s a reliable product that impressed during testing and was as straightforward to use as expected with any top-shelf air conditioning system at the moment.

Another alternative worth your attention is this one coming from Honeywell, a brand that specializes in indoor air quality control appliances, such as purifiers or dehumidifiers. Their AC units offer great results in cooling rooms up to 350 sq. ft., relying on the powerful motor that delivers 10,000 BTU. The same performance is granted by the Honeywell HL10CESWK. If you want an option for smaller spaces, you should consider the Honeywell MO08CESWK instead.

The MN10CES offers three cooling stages, from Low to High, so you can adjust the strength of the cool air current blown into the room. Moreover, you will enjoy a silent operation thanks to the dual motor that creates no more than 54 decibels on the top level.

Since we are referring to small models, it needs to be mentioned that this one measures 29” high, 18” wide, and 15” deep, so you won’t have trouble fitting it in narrow places. Just make sure you position it near a window, as it needs to be mounted on a bracket so it will take air from the outside. Worry not, as all the mounting components come in the box. It includes 4 wheels so it won’t be hard to move or uninstall it when the hot season is over.

Thanks to the front-mounted control panel, you can easily make the desired selections, or use the remote while standing 2 feet away. From the list of practical features, we remind the timer that allows it to go on and off after a pre-set time, and the dehumidifying setting that allows it to take out around 66 pints of dampness during a day’s work. Since it includes a self-evaporating mechanism, all the moisture will disappear without you having to empty a container. It also includes a handy filter that can be washed from time to time, to make sure it remains in proper usage conditions. As for the warranty, it enjoys a 12-month full warranty and an extra 4-year limited.

If you want to install the AC in the bedroom, you might want to check out the best quiet air conditioners since the units selected here are silent and won’t distract you’re your nocturnal slumber.

This SereneLife AC might not be the quietest model we feature in this top, but it’s definitely one of the most efficient when it comes to its core task – lowering indoor temperature. We are confident in this statement because it scored almost as well as the Frigidaire FGPC1244T1 during test trials. This is all thanks to the 12,000 cooling BTUs it produces that make it capable of cooling a room larger than 450 square feet in no time.

Unlike most of its competitors that stick to the classic functions you typically find in an AC, namely cooling, fan only, and dehumidification, the SLACHT128 provides an extra mode that makes it usable year-round, namely heating. So, when you’re cold in winter, instead of turning on the central heating you should give the AC a go. It’s likely cheaper to run or at least use it as a supplemental form of heating during cold days.

It can remove 3.8 pints of moisture per hour. This is more than enough to ensure you won’t need a separate specialty dehumidifier in the room you run this AC. As expected from modern air conditioners, it includes a 24-hour timer that you can use to reduce running costs. This is an important asset, even if the machine itself isn’t all that costly to run from the get-go since it has a low power draw.

To make sure the cold or hot air that it’s returning into the room is as safe as possible, it uses the washable filter to trap impurities lingering in it. Just make sure you don’t forget about routine maintenance or you might end up with dirtier air than before, and the AC will suffer performance loss in the process as well.

It features rolling wheels for simpler transportation from room to room. Since this is a portable unit, you will likely use it in multiple spaces of your home, so the wheels really do come in handy. The power cord is 4.3 feet long, which is shorter than the standard 6-foot length that we generally encounter with portable ACs. It features a digital control panel that grants an intuitive means to switch settings, and it even includes a remote control that you can use when you’re feeling too lazy to go all the way to the control panel.

The window mount exhaust kit is included with the package to spare you any extra expenses. Therefore, as soon as you receive the package you can set up the exhaust, plug the AC into a suitable power outlet, and run it to benefit from its cooling performance. The auto swing mode ensures even spreading of the cool or warm air into the room to add to the unit’s efficiency. Lastly, we want to mention that the manufacturer backs it against defects for the standard period of 1 year.

Our next choice is a peak-performance unit, suitable for locations measuring up to 700 sq. ft. so it’s a top choice for medium to large areas. The portability wheels ensure easy mobility all around, while the stylish design will match every type of décor. The dimensions reach 28.3” in height, 15” in width, and 17.5” in depth, making it one of the most space-saving alternatives.

It delivers 14,000 BTU, so we’re speaking of forceful cooling. Besides, if you switch to the Heat mode, you will also enjoy heating in the cold season, so it will be a worthwhile investment throughout the year. What’s even better is that you can use it for dehumidifying purposes, as well as a regular fan. The dehumidifier can extract an impressive 157 pints of water in 24 hours, being the ideal pick for very humid areas. In case you use it in these humid conditions, it should be linked to a drain so the water will be continuously discharged, otherwise, the self-evaporation will not be enough. Another great particularity is that it comes with a window kit that lets you connect the vent hose to the back of the unit and connect the window vent kit cover to the exhaust hose.

The 3-speed cooling fan lets you fully customize how intense or moderate you want the stream of air to be. Also, you have several modes to pick from, including a Dry one that maximizes the moisture-retaining abilities. The large removable and washable filter at the back helps retain dust and mold particles from the air, preventing them from spreading into the room. For nighttime, you have the Sleep option at hand, which keeps a low noise level and automatically adjusts the room temp to a comfortable level.

While there is a remote added in the box, you will enjoy a much more comfortable operation through the forward-thinking internet compatibility that lets you make the desired selections and observe the machine’s status by using your phone. Plus, the timer allows you to pick an hour within a 24-hour interval when you want it to start or turn off.

If it’s a small room that you seek cooling for, then you might want to look into a small window air conditioner instead.

5. NewAir Compact 8,000 BTU

Check Price at Amazon

Summary: Able to cool down a medium-sized room in mere minutes, it will turn out to be your helping hand during summer days. The compact design makes it ideal for confined spaces and even for relocating into a garage or an RV. Of course, the fact that it doesn’t take up much space makes it a cinch to find a spot to store it over winter.

  • One of the most compact picks, ideal for use in various areas of the house
  • Comes with the required window exhaust kit

Since the main criteria for picking the products for this cart is the size, we couldn’t overlook this compact and easily transportable model that can increase comfort in houses with limited-size rooms. However, being small doesn’t make it less effective than others, as it packs 8,000 BTU so it can cool rooms up to 200 sq. ft. It’s very similar performance-wise to the LG LP0817WSR, so you might want to compare the two side-by-side before you decide to make sure you’re getting the most for your money. 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. As it absorbs water particles, don’t assume you will have to constantly empty a storage compartment, as it has a self-evaporative system that takes away the hassle of that chore. When set as a fan, it circulates up to 170 CFM, so the cold air current will be easily noticeable. While dehumidifying the air, it also retains common allergens like dust mites or pollen and passes them through the washable mesh filter, offering in return only clean air to breathe.

It comes with the required window kit for mounting, namely a hose and venting kit that easily snaps together so you can perform the procedure yourself, without any professional assistance. This also means that you can easily take it done in a matter of minutes in the cold season when you no longer need to use it. Each setting is clearly labeled on the intuitive panel at the top, where you can find a button for selecting one of the two fan speeds, one for picking between three modes, and one for the useful timer that lets you create a specific schedule. It also has a remote.

Dual-hose portable ACs are generally more powerful than their single-hose counterparts, so you might need one of these instead.

With the same 8,000 BTU power, this one comes to the aid of those who want a simplistic device that is easy to mount and use. It’s not as slim as the previous but it boasts the same installation method so it can be used in multiple rooms in the house, as long as they don’t exceed 150-225 sq. ft. 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 clean the air as the unit 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. Also, it has a timer setting so you can pick any hour you want it to start or stop automatically, thus preventing you from running it the entire day and increasing the electricity bills. In the event of something going wrong, you will receive a service policy that covers labor for 90 days and the parts for 1 year.

Supplied with 8,000 BTU, it stands for striking abilities, too. If you want to cool and refresh a small area of 150 sq. ft., it’s one of the alternatives worth having on your list. It’s a must-have during summertime, as it won’t fail to meet your expectations. It’s among the smallest models, measuring 16.5 x 11.5 x 26 inches, so it can seamlessly blend into any room size, even a small office or garage. Handiness makes it more wanted considering that it can be moved around with ease thanks to the four caster wheels.

It features three operational modes. One of them is dehumidification which brings other healthful effects, including mold and germs elimination. It can take out around 50 pints of water during the day, so it will surely manage to improve the quality of the indoor air. If you’re looking for a heftier performance when it comes to dehumidification, then the Frigidaire FGPC1244T1 is a better option for you since it wicks 72 pints of moisture from the air within a day. The best part is that it self-vaporizes the water it gathers so that you won’t have to constantly empty the container.

The fan speed is adjustable to 4 levels, allowing you to optimize its functioning as you wish. For nighttime use, select the Sleep mode and it will not only run quieter but will also save energy. In case there is a power outage at some point, the unit will turn back on by itself and it will remember the previous temperature selections.

It has an LED screen that is easy to read and use, where you can adjust settings according to your liking. Even more, it comprises a 24-hour timer to turn it on and off at preset times. Included in the package, you’ll get all the needed attachments that make installation and usage optimal. The warranty provided is 2 years, covering the defects in parts and the labor.

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-sized 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 at 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 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.

This is the model to go for if you are on a budget but still want to invest in a qualitative unit. With an 8,000 BTU output and area coverage of 250 sq. ft., it’s a match for the more expensive competitors. The dimensions successfully keep it in the small-size chart, so you don’t have to worry about finding room to fit it. It’s merely 17” wide, 13.6” deep, and only 28” tall, and it comes with transportation wheels so you can easily move or uninstall it.

The air discharge is positioned in the front and is considerably large, so the chill air is effectively spread throughout the room. The fan is adjustable to two levels, Low and High, so there aren’t many choices available. However, it has 5 operating modes, including Sleep and Dry, the last being responsible for dehumidifying the air. The moisture collected must be disposed of manually, because the unit doesn’t include a self-evaporating mechanism like the NewAir Compact 8,000 BTU model does.

Other features include a programmable timer, an Auto restart, and two washable features that contribute to improving the air quality. Last, but not least important, the manufacturer protects their product with a limited 1-year warranty on parts and workmanship, while the compressor is covered for 3 years.

While it’s not the most powerful on our list, this model impressed us with its ability to cool rooms up to 300 sq. ft. even on the most torrid days. The 8,000 BTU makes it a match for small to medium-sized spaces. Measuring 18.3” W x 15.6” D x 30.1” H and packed with caster wheels, it’s very easy to move and install, especially since it comes with the mounting bracket, the exhaust hose, and all the other parts. The air discharge is placed on the front and is oversized, to enable the air to spread faster and more efficiently.

The AC feature includes three levels of intensity, along with a power-saving Sleep mode that can be used during the night to limit excess energy. Besides, the unit restarts on itself after a sudden shut-off, so you can rest assured knowing it will operate under safe conditions. The timer can be used to create a schedule based on your agenda, which is also helpful in saving energy.

Aside from the AC function, you can also set it to work as a dehumidifier, and it can eliminate around 60 pints of moisture in 24 hours, to help you improve the air quality of your living environment. However, keep in mind that the moisture will not self-evaporate, so make sure you keep an eye on the bucket. The unit will alert you when the bucket is full by beeping 8 times. It also has a washable filter installed that you have easy access to by removing the back grid.

Alternative Small Portable ACs Worth Checking Out


Aside from the models that we tested and included in our top, there are a few other products that we recommend you look into. These ACs were close enough to be included but we decided to only leave them as alternatives because of their similarity to our picks or because they came from the same brand as some of the models we selected for the main ranking. So, if you don’t find the model you are looking for in our top or you simply want to draw as many comparisons as possible before you decide to make sure you pick what is best for you, check out these alternatives too. Here is a brief description of their stats and their downsides:

10 Best Rated Small Portable Air Conditioner in 2023 – Cool Small Rooms

#1. Honeywell HL10CESWK


Check Price at Amazon
According to the ASHRAE-128 Standard, this Honeywell entry is rated to produce 10,000 BTUs. This makes it a suited option for spaces ranging from 350 to 450 square feet, so it has the same coverage as our top picks. Thanks to the dual motor technology it uses, this portable AC is one of the quietest products that you will encounter. So, if you need a cooling solution for rooms where a silent environment is a must, like the bedroom or nursery, this is a great option to consider. One of its major pluses is that it’s a self-evaporation model, which means that it boasts a bucketless operation. If there is high humidity in the room, you can set up a dual drainage system for the collected moisture to be automatically expelled. Another plus stands in the Sleep mode which is a preset 10-hour program during which the temperature increases at set internals. This helps save power while ensuring that the temperature is sufficiently reduced in time for the room to be cool when you wake up.

Why we chose to leave it out: It has the exact same cooling capabilities as the Honeywell MN10CES, so we decided to only include the HL10CESWK as an alternative since we found the design of our runner-up to be more interesting. Pick between these two models depending on which of them you can afford and like best design-wise.

#2. Honeywell MO08CESWK


Check Price at Amazon
Rated at 8,000 BTUs cooling power, this Honeywell entry cools medium-sized rooms in a jiffy. It’s an energy-efficient model that lasts for years regardless of how much you use it. But this isn’t much of a surprise considering the quality of all products that come with this leading manufacturer. The built-in dehumidifier function of this product is highly effective. Count on it to remove 44 pints of excess dampness from the air per day. Therefore, you won’t need a dehumidifier in the room where the MO08CESWK is set up. Another plus stands in the washable dust filter that helps clean the air by removing airborne particles. Additionally, since it’s washable, you won’t spend money on filter replacement considering that routine cleaning suffices.

Why we chose to leave it out: Since the Honeywell MN10CES is rated for slightly larger areas, we decided to include that model in our top and only include the MO08CESWK as an alternative for those who need an AC suited for smaller spaces of 250 to 350 square feet. Pick depending on the area coverage you need from the air conditioning unit.


10 Best Rated Small Portable Air Conditioner in 2023 – Cool Small Rooms

#3. Midea MAP05R1WT



We recommend this model for smaller-sized areas since it produces 6,000 cooling BTUs. It is fitted with a 3-speed fan that lets you choose the exact comfort level you prefer. Another customization perk it offers stands in the 24-hour timer that you set as you like to program its operation according to needs and that also helps reduce running costs. Speaking of, since this Midea model is rated at 6.1 for seasonal energy efficiency, you know from the get-go that it doesn’t draw a lot of power when it runs, so it’s a budget-smart solution. It’s as quiet as it gets, but during the night, if you want to make sure that no noise will distract your nocturnal slumber, you can run it in Sleep mode. It comes with a washable and reusable air filter that traps most of the polluting particles from the air pulled into the machine. Furthermore, backing against defects is provided for the first year after you buy it.

Why we chose to leave it out: Performance-wise, there is nothing wrong with this Midea product. We simply decided to leave it as an alternative suggestion instead of including it in our top since it has a lower BTU rating than the rest of the models we tested. However, if you need to cool a room of approximately 150 square feet in size, this model is your definite go-to.


10 Best Rated Small Portable Air Conditioner in 2023 – Cool Small Rooms

#4. Costway EP22783



A modern, smart air conditioner that provides optimal performance in spaces of up to 350 square feet. The window kit that comes with the package makes installation as versatile as it gets since you can set it up for sliding slash windows or single/double hung windows. Safety is guaranteed with this Costway model since it features a grid design and Child Lock, both features ensuring the safety of household members. To ensure a prolonged lifespan, the product features automatic defrost that keeps the internal parts from having frost build up on them in low-temperature conditions. It comes with a remote control that has a 16.5-foot range, allowing convenient use since you can change settings without going all the way to the AC. Best of all, it’s a reasonably priced model compared to similarly performing units.

Why we chose to leave it out: The only reason why this powerful 10,000 BTU AC features here instead of in our main top is that it had fewer online customer reviews compared to our selections. Thus, we are not as sure about its performance in the long run compared to that of its competitors. However, considering that Costway is one of the leading brands in this market, there shouldn’t be any issue in the durability department.



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, crawl spaces, or rooms that don’t have a window. You must also make sure that there is a power outlet nearby that the cord can reach.
  • Power Analysis: As it concerns the power, make sure that the electrical grid will furnish 120V, at a 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 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.

Frequently Asked Questions

Do portable ACs require a window vent?

Yes, they do require it, as installation cannot be done differently. So, when installing them, it’s recommended to be close to a window, as well as a power outlet.

Can I leave the AC ON for an entire day?

It’s not a problem to leave it ON for long periods, even so, it will increase the electricity costs, so you have to be aware of this aspect.

How long do AC units last?

A unit like this can provide you with up to 15 years of long-term performance. Nevertheless, appropriate upkeep plays a very important role in its lifespan.

Do I need to drain the portable AC?

Most models come with auto-exhausting systems, so they will get you rid of the task of manual draining. Even so, some don’t comprise this feature, so you will have to manually drain the collected humidity.

Can I place a portable model in my RV?

Yes, you can, as this type is compact and mobile. As long as you provide a window and a power source, it will operate the same as if it were installed indoors.

Do small ACs waste lots of electricity?

It only depends on how long you keep it ON. Actually, leaving it turned on all day long might lead to extra costs on the bill.

Are compact ACs silent?

Most of them come with low decibel outputs, so they provide quiet operation so that you can perform your daily activities with no disturbance features.

What should I do to maintain my AC unit?

It’s important to properly drain it (if it doesn’t drain by itself), and wash and replace filters when necessary. These two aspects will lead to many years of use.

Is a portable AC better than a window one?

The first take up much less space and are easy to move and uninstall when no longer needed. So yes, they could be a better option, but this will solely depend on your needs.

It’s the biggest we have encountered, so we highly recommend it if you struggle not only with high temperatures but also with increased humidity which might intensify the feeling of discomfort.

This one manages to check both these requirements. It’s small, easy to move out of the way when not in use, and doesn’t create an unpleasant humming sound while functioning. The noise level hardly exceeds 51 dB, so it can be kept on during the night. It also offers a Sleep mode that turns it off after the temperature has decreased.
