The summer sun beats down and you’re trying to keep your home cool. There’s no breeze coming through the windows, and there’s no central air conditioning either. That’s where portable air conditioners come into play, and so does your need to get the best portable air conditioner for your specific use cases.

I’ve been there, done that, and found that portable air conditioners offer the ideal solution. You’re able to move them from room to room, plus you don’t have to fork out for installation. Furthermore, older adults and young children avoid the dangers of a home that’s too hot.

So, how do you find the right portable air conditioner? I’ve looked at a range of models, from 14,000 British Thermal Unit (BTU) to evaporative air conditioners to help you make the right choice.

According to EnergyStar, a 14,000 BTU air conditioner can cool a space of between 550 and 700 square feet. However, this drops to between 400 and 450 square feet when using the air conditioner in a kitchen.

Honeywell HL14CESWK

With its sleek and compact look, this is an air conditioner that won’t clog up your room. It’s on the heavier side, as are all 14,000 BTU models. But it’s not so heavy that it’s impossible to move from room to room, plus it has small wheels.

Honeywell says that this air conditioner can cool a maximum space of 550 square feet. This puts it on the higher end of the totem pole for this type of unit. It only takes a couple of hours to cool the room, so you can pop it on during the morning to prepare for a really hot day.

I really like the adjustable speed setting, which lets you account for different temperatures. You have three to choose from, so you won’t freeze your house up when you only need a bit of cooling. The fan-only and dehumidifier functions also have variable speeds to match the overall speed setting. Overall, this might be the best portable AC unit for you if you prefer a lot of flexibility.

The auto evaporation feature also makes it stand out as a dehumidifier too. The air conditioner collects about 110 pints of water every 24 hours. However, you don’t have to keep changing tanks to collect it all because the air conditioner evaporates it away.

I’m also a big fan of the remote. It allows you to change settings while you’re on the move, plus it displays the temperature setting at all times. Of course, there’s also an LCD display with soft buttons on the unit itself if you want to get up close and personal.

The auto-shutoff feature will prove useful if you’re the forgetful type. It turns the air conditioner off every 24 hours, which lowers the risk of it overheating.

Unfortunately, the unit doesn’t offer you any way to control the direction of the air flow. It emits air from the top of the unit, which then spreads naturally across the room. If you want to have more control, you may need to place a fan above the unit that directs the air where you want it to go.

It’s also not the quietest unit around, coming in at 52 decibels (dB). This means you’ll hear a constant hum that sounds a little like light traffic. Still, it’s nowhere near the constant 85dB level that could damage your ears.

Has small wheels at the base to make it easier to move
Comes with a remote for checking and changing settings while on the move
Automatically shuts off after 24 hours of operation
Evaporates the moisture it takes in so you don’t have to collect and dispose of it

No way to change the direction of the air flow
Generates a fairly loud and constant hum

Whynter ARC-14S

The ARC-14S is different for the reason that it has triple function. It can be used as a fan, or as an air conditioner, or it can be used to dehumidify a room. It can work efficiently in any room, which is up to 500 square feet in size, however you might discover that this max comes down on extremely hot days.

Moreover, I like its dual-hose system, which makes the unit more environment friendly. The two hoses mean that the unit cools the room faster, when compared to other single-hose rivals. Also, this means that less power is required to keep the unit running at supreme capacity.

With the materials made use of in the unit, Whynter carries on this environmental focus. For those worried about their carbon footprints, this unit may be a good choice, as, R-410A refrigerant does not diminish the ozone layer. It also makes use of lead-free constituents, all of which conform to the standards of European Union’s Restriction of Hazardous Substances (RoHS).

However, it does not come with a feature of auto-evaporation. But, it has an auto-drain system that averts the inner tank from filling up so much that it drips. The unit uses the water that it draws in, and, recycles it to make cool air.

Though, the thing that I most like about it is that it can be the venting kit that lets you to fit the unit in a window. Also, this makes it simpler to put the intake and use hoses in places which do not have an effect on your home. Also, it is a multipurpose kit, having a slide bar plus the fittings you require to attach the unit to the ceiling or wall.

At 80 lbs, it is heavier than most of its kind. It will need two people to lift and install it. But, in case you want to use it as a freestanding unit, you can move it between rooms by using the little wheels on the base.

It can be used as a freestanding unit, or can be fixed to a surface, owing to its many installation options
Refrigerant doesn’t lead to the depletion of ozone
It makes use of lead-free components, and, thus is environmentally-friendly
The water collected is recycled by the auto-drain system, and, is then used in cooling
It has three kinds of settings

Not very efficient in cooling any room over500 square feet
At 14,000 BTU, it is one of the heaviest units around

DeLonghi PACAN140ES

Just like the other units on this list, DeLonghi PACAN140ES provides triple functionality, with a dehumidifier as well as a fan being the package’s part. Though the weakness of DeLonghi is that it suggests that it can work efficiently in a room, which is merely up to 450 square feet in size, something which most of the other 14,000 BTU units can handle effortlessly.

However, there are still many reasons because of which I have added DeLonghi to my list. And, one such reson is that – for the ones concerned about allergens in their home, it is one of the best portable air conditioning units. It makes use of a BioSilver air filter, which means it catches any pollen, dust, or any other allergens, in place of re-circulating them in the air.

Thanks to its Whisper Cool technology, it is also one of the quietest 14,000 BTU units. DeLonghi states that their unit generates 50% less sound, when compared to others, although this appears like an unclear metric. And the fact is that you will still have to hear the ‘hum’ sound that comes from most of the portable units, however, it is not as disturbing as other powerful units on this my list. Overall, if you are looking for the quietest portable air conditioner, then DeLonghi is the best choice.

Although, its dehumidifier is not one of the strongest. At the maximum setting, in 24 hours, it can get clear 84 pints of moisture. This is perhaps sufficient for the majority of the individuals, however, in case you stay in an extremely humid area, you may want to think about a unit with a stronger dehumidifier.

It is heavy in weight, although it has wheels to move it easily between the rooms. The cooling features can be controlled through the unit’s LCD screen or the remote, which comes with the package. The thing that I liked about the DeLonghi is its built-in timer that allows you to choose at what time in the 24-hour period the unit will function.

Also, you don’t need to worry regarding the troublesome water tanks. Similar to the ARC-14S, this unit also recycles the air which it consumes into the cooling unit.

It is a single-hose unit that means it is not as effective as others. This might not make it the top bet for the environmental conscious people. Nevertheless, the noiseless operation means that it is a better choice for bedrooms, than most of the other 14,000 BTU units.

Lets you to set diverse cooling periods in 24-hours
Due to the BioSilver filter, you don’t need to worry regarding allergens in the air
Noiseless, when compared to most of the 14,000 BTU units
The water collected is recycled, and, is then used in the air conditioner

it becomes less efficient, owing to its single-hose setup
When it comes to square feet covered, it is one of the least powerful 14,000 BTU units

Haier HPN14XCM

The first thing that I noticed about this unit is its design. With a sleek blend of black and silver, it will easily fit in homes having a modern décor. I believe that as a kitchen unit it might chiefly be an optimum choice, which doesn’t look out of the place.

It can work efficiently in a room, which is up to 700 square feet in size, which makes it one of the most powerful units on my list. Although, this is affected by the amount of light and shade in the room, and I believe it is best in a room of around 500 square feet.

It is 83lbs in weight, which is around the same as the other 14,000 BTU units. It can be easily used as a freestanding unit, as, it has wheels at the base. There is a window kit with the unit, which lets you to install it in any sliding window having a maximum width of 46 inches.

The unit has soft buttons, because of which it gets simple to switch amid the three cooling settings. Also, it has a remote, however it doesn’t tell you the temperature at which you have set the unit. This means, prior to you find the right setting, you will need to involve in a little speculation.

Also, I liked the safety focus of this unit. It has an approval from The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), which means that its standard of manufacture is high.

However, the instructions are not as clear as they ought to be, and, they bring the package down. For instance, in order to make use of its dehumidifier function, you may have to experiment with the unit.

Its single-hose design, and the fact that it is a bit nosier, when compared to others, make it a power guzzler. However, I liked that you could set it to work at numerous times of the day. Also, it recycles some amount of water that it takes in, supposing that you can make the dehumidifier function.

Has the kit required to install it in a window
Has ASHRAE certification
Beautiful modern design
Has the capacity to cool rooms up to 700 square feet

Vague guidelines mean that a bit of guesswork is required
Not the most silent 14,000 BTU units

EdgeStar Extreme Cool AP12000S-KF
EdgeStar Extreme Cool AP12000S-KF (now known as Koldfront AP12000S-KF) has a 12, 000 BTU or British thermal unit. This is the cooling capacity and with this amount of energy, it can effectively cool a 425 square feet of enclosed space. This is best if you are living in humid locations. It also utilizes an auto drain system which uses most or all condensates that it collects. Under intense humid conditions, the in house tank fills up immediately.

10,000 BTU Models
It is highly advisable to do some researches first before buying an air conditioner. You must know how many BTUs you are going to need. The size of the room should match to the corresponding value of your BTU. According to North cool, a 10,000 BTU can cover the room with 450 square footage. This is just an estimate and it is based on an average room conditions in moderate climates. Kitchens for example, may have 450 square foot area but since it is hotter there compared to a regular room, it may require higher BTUs.

Honeywell MN10CES
Honey well is a portable, powerful, and high quality product. It has a 10,000 BTU which can absorbs up to 66 to 70 pints of water daily with continuous drain option for long unattended operations. It has three in one functionality which includes air conditioner, dehumidifier and a fan (High, medium, low) all in a single unit. It also has a auto evaporative system which eliminates the need for regular maintenance.

This is already a good performing machine for its size and appearance.

Honeywell has an auto evaporative system which allows you to enjoy other tasks inside the house without worrying about the draining process of its water. It evaporates the water and duct out the water through the use of the exhaust hose.

Honeywell is a non-noisy portable air conditioner too. It has a range of 50-53 decibels (dBA). There may be little sound but not much to disturb you when sleeping compared to other brands in the market.

This is pretty easy to install. You just have to follow the guidelines on the insert tips inside the box upon purchasing it. The only major thing to consider is the tightness of the window kit. Be sure that there are no gaps to allow the machine to function efficiently.

Honey well has a dimensions of 18.1 inches wide by 15.2 inches deep and stands 29.3 inches high and weighs under 64 pounds. These figures are from space done right. Changing positions has never been easier with its caster wheels and handles for easy maneuver.

Furthermore, it comes with a five year warranty which is one of the best offers in the market when it comes to air conditioners. With all these features enumerated, we can say that you have value for money in purchasing this item. It gives you quality, reliability, affordability and convenience.

• Excellent dehumidifying capabilities for such a small unit
• Lightweight enough to easily move between rooms
• Evaporates the water it collects so you don’t have to empty any tanks
• Quick and easy installation
• Full function remote control for easy operating
• Very quiet when maintaining a room temperature

• Louder than advertised when the compressor kicks in to cool the room
• Stiff exhaust hose limits how you position the unit

This unit is a 10,000 BTU which can cool a room approximately 20’ x 20’. It is in an acceptable performance if the room size is below 250 square feet. Unfortunately, beyond that size it may be difficult for this unit to cover the entire room. It has vertical motions which create a constant temperature.

This is a combination of cooling, fan and dehumification. Unlike the Honeywell, this unit has internal tanks. This also has a LED digital display which is designed to easily monitor temperature. It also has a remote control for ease in operation.

It has a side out filter which you can just easily wash under the faucet and can be reused over and over again. The maximum length of the exhaust is 4 feet and 11 inches. It has four caster wheels for easy movement.

I like that the Black+Decker Model No. BPACT10WT has an all-in function as air conditioner, dehumidifier, and fan which is easy to program. It also has a function which allows you to set the unit’s operation over the course of 24 hours. The feature I like the most about this portable air conditioner is its full function remote control, which has its own LED display screen so you can always keep track of the temperature.

I admire that this unit has caster wheels for mobility, although it’s not that hard to lift or transfer because it weighs less than 50 lbs. There are also built-in handles on both sides as an alternative in case something goes wrong with the wheels.

Unfortunately, this unit is one of the noisier 10,000 BTU models. It particularly makes a loud noise whenever it switches itself on or off. Still, the product comes with a 12 months warranty for parts or manufacturing defects and 12 months warranty for labor.

Auto-evaporation features means less cleanup
The filter slides straight out so it’s easy to clean
Excellent remote with its own LED screen
Long hoses for more placement options

Very noisy, especially when it switches on or off
Limited room coverage compared to other same-level units

LG BTU Portable Air Conditioner Model No. LP1015WNR

The combination of a two-way fan and two-way air direction makes this unit stand out from the other portable air conditioners. These multiple fans cover a wider space up to 250 square feet for the distribution of cooler air. The unit also comes with a top mounted control panel and a remote control. The remote control is a bit difficult to get used to because of the small buttons.

This unit also has a built-in dehumidifier for keeping small spaces dry. It is capable of collecting 2.6 pints of water per hour or about 62 pints of water per day which is stored in an internal tray. The indicator on the display panel is helpful in indicating when the tray is on the verge of filling up. However, I observed that the tank fills up quickly. When used as a dehumidifier or air conditioner, you may have to empty the tank every couple of hours.

The Model No. LP1015WNR is slightly heavier at 55 lbs compared to other BTU portable units but it has caster wheels so you it can be transferred from room to room easily. Aside from that, the product comes with window fitting kit, but the instructions aren’t that helpful for beginners of first-timers in installing a conditioning unit in a window. It may take time to measure and fit the air conditioner.

It produces the usual sound or general hum for most air conditioners which might be uncomfortable for small rooms.

Adjustable multiple fan allow for a larger coverage
Side grooves for easy transfer
Dehumidifier works well in most conditions
Control panel for timer functions and water level indicator

Poor instructions make setting it up in a window
Small internal tank that requires constant changing
Buttons on the remote are a bit small

The Costway portable air conditioner is a classic and simple portable air conditioner suitable for home or office. This unit goes for a no-frills design with an all white color.

It has a top mounted control panel which indicates the temperature, timer, water level indicator, and others. However the buttons need more pressure than usual to work. If the buttons are a bit cumbersome, the unit also comes with a remote as an alternative. The remote may even be used across the room to change the temperature or fan speed. The unit may be programmed for 24 hours or specific schedule depending on what you want.

Costway Model No. EP22783 has a two-way fan system, built-in dehumidifier, and air conditioner. The two-way fan system circulates air evenly to spread cool air inside the room. It also has an auto-condensate function for recycling water collected inside the unit. As usual, the internal water tray has to be changed several times a day. The control panel indicates when the water tray is full.

Unfortunately, this unit is not the most powerful 10,000 BTU portable air conditioner because it only covers small spaces up to 200 square feet. It comes with a 5ft hose that allows you to position it away from a wall to get a more even air flow. Included also is a window seal plate.

Has caster wheels and grooves built into the sides for portability
Long hose offers you some options when it comes to positioning
Recycles a small portion of the water that it takes in
Allows you to set timers over a 24-hour period

Less cooling power than other 10,000 BTU models
The hose generates a lot of heat due to lack of insulation

8,000 BTU Models

When it comes to cooling areas, 8,000 BTU air conditioners are capable or covering wider areas up to 350 square feet. However, even with this specification, 8,000 BTU air conditioners are best used in smaller spaces. The cooling power of the air conditioner will be maximized well in rooms around 100 square feet to 200 square feet.

LG BTU Portable Air Conditioner
Model No. LP0817WSR

The dehumidifier works well with small spaces like a bedroom or office room. It does have a water level indicator when it’s time to empty the water tray.

For ease of access, this unit comes with caster wheels even if only weighs 58.4 lbs. Included in the package is a widows installation kit too.

The auto-evaporation system recycles the water it collects for use in cooling

One of the heaviest 8,000 BTU units on my list
Quite loud given its lower air output

In October 2017, the Department of Energy implemented a new test procedure to determine the BTU rating of portable air conditioners. The procedural change has adjusted the amount of BTUs allowed to be claimed downward by as much as 50%. There have been no internal changes to these units, and the functionality remains the same. Please refer to room size guidelines to find the portable air conditioner that best meets your needs.

This can handle most rooms of up to 250 square feet. It also contains an auto-evaporation system, which works well in regular conditions. If you use the dehumidifier, expect to empty the occasional tray.

Speaking of the dehumidifier, it can absorb about 45 pints per day. This puts it on par with most other units in its class and should be fine for the average living room or office space. You also have a choice between manual and auto-draining for when the water intake exceeds the evaporation system’s capabilities.

The R-410A refrigerant, plus the unit carries RoHS certification to say that it’s free of lead components. This means there’s no risk of toxic lead particles finding their way into your air supply. The Whynter ARC-08WB portable air conditioner is compact, portable and easy to set up, even in small spaces.

It’s a surprisingly heavy unit given its compact size, weighing in at about 64 pounds. That means you need to take care if you’re using the plastic window fitting kit, as one false move could break the kit. It does have chunky caster wheels though, so it’s easy to move between rooms.

The touch panel on top of the unit controls the settings, which include a timer and auto-off function. You also receive a remote, though it’s not much use if you’re not in the room with the unit.

Honeywell MF08CESWW

The Honeywell MF08CESWW 8,000 BTU Portable Air Conditioner, in white, is smart with a modern design, cooling and dehumidifying areas up to 250/300 square feet. With 3-in-1 technology and an environmentally friendly compressor, this portable air conditioner delivers optimum cooling and dehumidification. Design elegance defines this unit, as it has several clever touches that may make it the cleverest air conditioner in its class. I particularly like the little groove at the top of the unit, which you can slot the remote into when it’s not in use. The filter’s also accessible from the side, so you don’t have to open the unit up to clean it.

It’s quite powerful too, being capable of cooling room of up to 300 square feet. Couple that with a dehumidifier function that collects over 60 pints in 24 hours and you have a unit that packs quite a punch. I also like the fan-only mode, which means that you don’t have to spend more on a portable fan.

The full-function remote control allows you to operate each feature from across the room and can be stored on the unit when not in use. You get a window fitting kit with the package, which is surprisingly easy to install. The detailed instructions help, so you should have it up and running in less than half an hour. That’s a major plus point given how fiddly some of these window fitting kits can be.

It has a litle problem with the vent hose though. Neither it nor the area where it seals into the unit have any insulation. This means they become hot to the touch and also transmit some heat back into the room.

However, it’s the lightest of the units I’ve looked at in its class, weighing just over 50lbs. The little castor wheels help with portability, plus they tuck nicely under the unit so you can’t really see them when they’re not in use.

If something goes wrong with the remote, you have to shell out for another one as there’s no other way to change the temperature settings.

Has practical design features, such as the remote control groove and easy-access filter
Very powerful considering its low BTU rating
Uses an evaporation system to ensure the unit doesn’t overflow with water
Light enough to carry and install fairly easily

No in-built control panel
Exhaust hose gets hot due to lack of insulation

Evaporative Air Coolers
The difference between evaporative and regular portable air conditioners is the lack of an exhaust hose. Also known as swamp coolers, these use the moisture they collect to cool the air, so there’s no Chlorofluorocarbons (CFCs) or refrigerants in play. This makes them friendlier to the environment and they use less power since it’s more energy-efficient to pump water than to compress air, though they don’t cool as well as portable air conditioners.

Honeywell CL25AE
A cooler capable of cooling 500 cubic feet per minute (CFM), this works best in fairly dry conditions. The manufacturer recommends not using it whenever humidity exceeds 60%, as the air can’t absorb enough water for effective evaporative cooling. Still, it’s powerful enough to cool an area of 300 square feet, which puts it in the same league as many portable AC units.

    If a permanent wall-mounted air conditioner isn’t what you’re looking for, consider a window air conditioner, which combines the efficiency of wall units and some of the maneuverability of portable units.
