2. BLACK+DECKER BPACT08WT 8000 BTU
Black and Decker have been one of America’s top brands for decades. Quality builds, long-lasting, time-tested products, and a unique way that they build their machinery all play a part in their success. When it comes to building portable air conditioners, they’re one of the best. With a keen eye for user-friendly aspects, their 5,000 BTU unit comes out of the gate swinging.
This unit has a vertical ventilation system, offering a substantially better airflow than most competitor models. This allows you to cool off your spaces relatively quickly, even if they call for a slightly-higher BTU output. Paired with the attractive pricing (and the fact that the ventilation filters are absolutely simple to clean), we fell in love with this model.
While 5,000 BTUs (thanks to the 2017 regulation change) isn’t the highest, what this unit lacks in power, it makes up for in additional features. The window kit is a breeze to install, while the configuration settings make it easy to determine a preset preference, and flip to it the moment you get home. If you plan on moving this around a bit, you’ll be delighted at how easily the wheels move.
Overall, this is an excellently-priced, superior quality portable air conditioning unit for any occasion. 5,000 BTUs of power is ideal for bedrooms and smaller common areas. Black and Decker consistently delivers high quality products, and to say the least, our expectations were exceeded with this one.

3. Frigidaire Cool Connect 12,000 BTU
This is one truly epic piece of tech that pushes the boundaries. Al portable AC units will need to output the hot air created by the motor, but this is the closest we’ve gotten to seeing a unit not requiring window slats. You can leave this in the center of the room and activate fan settings, or pull the hose over to the window and enjoy cool, refreshing air.
Frigidaire was the world’s first consumer refrigerator brand, bringing innovation to the frontlines—with their portable AC, they’re reinvented comfort. Use the Wi-Fi control function to manage your AC from across the room (or house), while keeping it more towards the center of the room for utilize the 360-degree airflow feature.
It can be a bit dodgy when you’re trying to get the full use out of this unit. While you want to utilize the 360 airflow, it’s inevitable that you’ll end up having this unit closer to the window rather than the center of the room. This is going to create a few cold patches, and a few hot spots in the room. With a killer 12,000 BTUs of power, it will quickly even out, and turn your room into an ice chest, but keep the 360 function in mind when deciding on where to place it.
This unit also takes three pints out of the air per hour, helping you to cool the motor during use. You very sparingly need to access the small bucket (accessible via the back) for draining. Download their app on the Play Store or App Store, and control your comfort right out of the box.

4. LG LP0817WSR 8000 BTU
LG will always be one of our favorite electronics providers, especially when it comes to in-home appliances. From air conditioners to stoves, fridges and beyond, they’ve become an American staple in every home. This portable AC unit comes into play to complete your space, and seriously cool down your medium-sized rooms with ease.
With some killer dehumidification power and auto an auto evaporation setting, you can completely control the comfort levels of your space, while providing up to 5,500 DOE BTUs of cooling capability.

You also get a programmable system to control cooling—initiate it just before you get home, and walk into a cool, calming space right from the get go.
We were a little disappointed with the rear build—the metal vents that control the filtration and intake system are easy to dent/damage, which can interfere with air intake, proving problematic for extended use. Keeping the AC away from children, and ensuring it’s not jut up against the wall/baseboard radiator should help prevent these issues from occurring.
You’ll be able to move this around freely with a six-foot power cable, and simplistic window mounting system. Made of lightweight materials, this is easy to move around the room, or into a new room for guests/moving bedrooms in a flat. Even with a few minor issues, LG still dominates the field in home appliances.

The unit is capable of handling 163 cubic feet per minute (CFM) of air and can remove up to 79 pints of water from the air in any given 24 hour period. It’s quiet, efficient and you don’t have to be a football player to move this unit around the house.
If you’re looking to keep a large room cool and dry this is the unit. While the advertised 450 square feet might be pushing it a bit the unit will in fact keep a large room of a few hundred feet cool and dry without much effort. We found the remote to be maybe the most important component of this portable air conditioner because in a big room you become aware of how short the power cord is (the exhaust hose too for that matter). And if you’re seated 20 feet away you don’t want to have to keep getting up to adjust the settings on your AC. That said performance was right in line with expectations and we found ourselves flipping between air conditioning and fan mode pretty regularly, which indicates the AC was doing its job.

Power cord on this portable air conditioner could definitely be longer than it is.
8. EdgeStar Extreme Cool 12,000 BTU
Make no mistake about it, this model is not cheap. It redeems itself though by being as effective as all get-out at cooling down your room and transforming it into a cool, dry, healthy environment where the deer and the antelope may not play but you and your kids certainly will. With the dehumidifier pulling an unbelievable 90 pints of moisture a day out of the air you won’t have to spend any more time worrying that the dampness is ruining your furniture.
The Edgestar has an edgy design that may at first seem a bit self-conscious but will eventually grow on you. The unit itself is quiet and effective, fairly lightweight and easy to move around and the venting system is easy to set up and move with the unit. When set up in a room of appropriate size and environmental conditions this portable stand up conditioner will make short work of the heat and humidity and have everyone in the house breathing a bit easier.
- Weight69 pounds
The nice dry spaces this portable air conditioner creates will discourage the growth of potentially harmful mold making your home a healthier place for all.

The fact that this portable air conditioner costs north of $500 is not its strong suit, but we understand that quality can be expensive.
The feather touch controls are a little too feathery and can often be triggered by just being near them.
9. SPT WA-1420E 14,000 BTU
This SPT 14,000 BTU isn’t going to win over many with its somewhat clunky design but it will earn legions of fans once they get a feel for how well it can cool down a substantial sized room. Whether or not the laws of thermodynamics will actually allow such a unit to effectively cool down a 700 square foot room is open for discussion but the fact is the unit does a great job on some great big rooms and for that you should consider buying it for your home.
While this portable air conditioner has a look only its designer could love it nonetheless works like a charm and that’s all we really care about. You can set things up by running the fan for a while, switch to dehumidifier to dry things out and then switch to air conditioning mode and cool things down to boot. The finished product will remind you of central air effects and you won’t have to wait hours to reap the cool, dry benefits. It’s not the cheapest or the quietest portable ac on our list but it works like nobody’s business.

11. Frigidaire FFRA0511R1 5000 BTU
The Frigidaire 5,000 BTU Window Mounted is one of only 2 window units on our list. It earned a spot by virtue of its reliable performance, ease of setup, highly effective cooling abilities and the fact that it can be had for just over a hundred bucks. This is not a unit built to cool banquet halls. It’s a bare bones unit built to create a cool, dry environment in your smaller rooms. It will do an excellent job as long as you stay within the parameters laid out in the specs.
While our list has been devoid of window units up to now we simply couldn’t ignore the exceptional utility of this portable air conditioner. From the effortless setup to the long power cord that reduces dependence on extension cords to the fact that it does a great job cooling smaller rooms without sending your electric bill into the stratosphere the Frigidaire 5,000 BTU unit will make a believer out of you the first time you use it.

Portable Air Conditioner Buying Guide & FAQ
What is a Portable Air Conditioner?
Rather than slipping a large and bulky air conditioner into your window (which looks horrible from the outside, by the way), you’re able to freely move your unit throughout the home. Yes, it still has to be plugged in, but you aren’t constricted to only a room with windows, or a room you don’t want to be in, solely for the need to beat the heat. Running vents to the window slat is easy, and generally takes no more than two or three minutes.
They operate quieter and throw less heat, on average, than your standard window units, and provide complete freedom from wall units. Installation, weatherproofing, and maintenance (both interior and exterior), are all issues that wall unit owners face. Portable ACs still need to be cleaned and have their filters scrubbed from time to time, but don’t require the same attention that alternate units need.
In short, they move around freely, provide rivalling or superior power to window units, and allow you to just pack them up and go.
Pros of Portable AC Units Over Wall and Window Air Conditioners
- No Weatherproofing: Wall unit owners may have their reasons, but there’s nothing better than not having to weatherproof the exterior of your AC unit, and the space between it and the wall of your home.
- Non-Invasive Means: Focusing on wall units again, there’s a lot to do. You have to cut a hole in the wall, make a mount, or adjust the preexisting one to your current AC. If you end up buying a newer wall unit, you’re constricted to the size that your old one was, otherwise you risk skipping on proper insulation, making the point of air conditioning a bit useless.
- No More Rain: Window unit kits (referring to the accordion doors, plastic slats and screws, etc.), are always a pain in the neck. They take time to properly mount, and always allow condensation to form around the edge of your AC, which can ruin your windows over time. If rain is getting into your home, that means you don’t have a tight enough seal, and you’re throwing your cooling money out the window.
- Less Power on the Same BTUs: We’ll get into BTUs in a moment. As an industry standard and threshold for quality, most portable air conditioners are running on less power, and come with higher Energy Star standards than window/wall units. Saving more money, on top of saving money for better insulation—there’s virtually no downside to going for a portable versus window or wall units.
Don’t portable units with window slats/vent pipes compromise insulation and allow weather to get in?
The window slats you receive with your portable unit come at a much higher thickness than the accordion doors that come with window units, and only allow rain/moisture to access the same sections of the window that they normally would, even with the window closed. The slats usually lean far outside of the window to allow for better insulation.
Portable ACs Are Foolproof
With no 220v outlets needed and a completely foolproof cooling method, you’re getting everything in one package. There’s no room to mess up insulation or placement; you roll it into the center of the room (or your corner of choice), run your hose, plug it in, and you’re good to go. All human error is taken out of the equation; you can’t waste money with your cooling costs unless you roll it outside or leave the window open. It’s the quickest setup, with the most reliable
How do Portable ACs Work?
Let’s dive into the anatomy of a portable air conditioning unit and talk about each part. As with any unit, you have the electric motor that generates heat (ironically). This plus your coolant act as the essential heart and blood of your machine. Depending on the BTUs that your machine can generate, your machine may require more dedicated power or throw off more heat. That leads you to your vent unit—running this to the window allows the generated heat to collect in a safe area, and funnel its way outside.
Those are your working parts. Then, you come to your electrical system that lights up your control panel, or at the very least, receives commands from the buttons. Cool air runs through a separate conduit to your vents, effectively cooling off the room while you mess with the controls. The thick ABS plastic shell found on most models properly houses everything without risk of damage, while providing enough insulation to keep temperatures in the room at bay, while keeping the cool air inside.
Do You Have To Drain A Portable Air Conditioner?
With some, yes. With others no. If you think this is going to be an issue for you make sure you find out whether the portable air conditioner you have your eyes on requires manual draining or has an auto-evaporation feature.
How Do You Set Up A Portable Air Conditioner?
Setup of a portable room air conditioner is typically very simple and painless. Anyone with the ability to follow directions should have no problem. The biggest thing to keep in mind is that the heat an air conditioner removes from the air needs to be vented somewhere. If it’s simply allowed to escape back into the room the room will never get cool. Because of this a AC usually comes with a venting kit that fits in the window and accommodates a flexible hose that runs from the unit. Hot air is vented through this hose to the outdoors. This will take a few minutes to set up but once it is your unit is ready to go.
Portable Or Fixed Air Conditioning System?
When it comes to such things as home air conditioning your primary concern should be cost. Installing a central air system may make your home a uniformly delightful place to live but it may also cost so much you can’t afford a night out. One of the great benefits of the portable air conditioner is its low acquisition cost, its free installation and the fact that you’re typically cooling only a single room for part of the day or night and as such your energy bills won’t go through the roof.
Things To Consider When Buying a Portable Air Conditioner
Keep in Mind – The portable ac will need to be set up near a window so that the heat it pulls from the air can be vented to the outdoors. If the room you intend to cool doesn’t have a window you’ll either have to improvise some sort of vent or simply forget about an air conditioner. You’ll also want to be sure there’s an outlet near the window. The power cord on most units is not that long so the outlet and window should be near each other lest you need to use an extension cord, which is not such a great idea. Lastly, make sure your new unit has both a washable pre-filter and an additional carbon filter. These filter dust, mold spores and pollen from the air and make the environment healthier.
Noise Plays a Part in Your Selection – We’re not crazy about putting everything into a crazy scientific light—if you know a thing or two about decibels, then we applaud you. Decibels or DB, as you may see them referred to on sales pages, are measurements of sound. How loud a sound is depends on the decibel quantity. For instance, a human being breathing on their own registers as about 10DB. That’s not that bad. Then, a standard air conditioner unit is roughly 50-75DB. So that’s like having all your friends sitting next to you breathing. You’re pretty familiar with how your old A/C sounded, but with a portable, you can position the hose and vents to mess with the sound just a little bit. When you’re looking at your next potential air conditioner, pay attention to the decibel rating so you know what you’re getting yourself into.
Single vs. Dual Hose - This is usually something that we, as a society of consumers, just pass right on by. This matters way more than you think in terms of personal safety and efficiency: single hose or dual hose, what’s the better option?
Single hose units are alright for small spaces, but they mess with the air pressure in your space. If you’re in a bedroom, and your door is closed, you’ll be able to feel a vacuum-like effect—however minor it may be—when you open up the door. That’s because you have all that air being sucked in through the façade of the machine, and the hot air being pushed out. Between temperature and suction, you have an odd effect. If you’re using the single hose unit in a room with other electronics, and those are on and drawing heat, you’re better off going with a dual hose unit.
Dual hose units are unique—the other hose is sucking air from outside, running it through the machine (usually there are also suction points on the bulky body of the machine as well), and this makes for a far more efficient process. However, the term portable becomes relative here. These units are sometimes a bit bigger, but they do a better job for larger spaces. You won’t feel that vacuum-like effect, but they feel more permanent than single hose units do.
BTU (British Thermal Units) and What They Mean – You found the right portable air conditioner for your needs. Budget-friendly, ergonomic design, long hose, and you like how it looks—but hold the phone, that’s not really the point. The point is that it does the job that you need it to do, and does it without interruption. That’s when you look at the BTUs on a unit, which are measured like so:
We use BTUs in the United States more than they do in the UK—go figure—but what do they represent? It’s the amount of thermal energy that needs to be properly generated. That thermal energy is used to raise the temperature of pure liquid to the prime point for water density—39F. For every BTU in a unit, you’re used just over 1K watts of energy per second. That’s why you freak out when the electric bill comes in every month.
However, BTUs are also how we decide how cold it’s going to make our room. You may notice guides that tell you how many BTUs a unit should have depending on what size room you’re going to throw it into. When you’re dealing in portables, the more BTUs there are, the higher the price tends to go. There are such things as window-mount units that exceed 20,000 BTUs. You’re going industrial there, but the point is it’s rare to find anything like that in a portable.
However, how many BTUs do you really need? Here’s a quick little chart to tell you what you should be looking out for.
- 200sq foot area – 4,000 BTUs
- 500sq foot area – 10,000 BTUs
- 1,000sq foot area – 20,000 BTUs
Basically, you’re looking at about 2K BTUs for every single 100sq feet of space. Now’s the time to us all that math you learned. Grab a tape measurer and figure out your room. Don’t get caught up in, “I want it to be freezing in there.” If you’re using an overkill portable air conditioner in a small space, it’s still outputting the same temperature. The only difference is, it may get there a little bit faster, but it’s going to spike up your electricity bill.
Are PAC Energy Efficient?
If you pin a 10,000 BTU portable unit against a 10,000 BTU wall unit, the portable is going to win for energy efficiency. You never have to use above a 110/120 with a portable unit, as opposed to wall ACs. When it comes to window units, it solely depends on the Energy Star rating of each unit, as they tend to use the same power supply.
In general, however, PAC units are energy efficient (especially when you compare them to central air). You will spend less on average monthly/yearly cooling costs with a PAC as opposed to other models. The right brand and model completely matter in accordance with the longevity of the unit, which is why we’ve singled-out the top ten on the list above.
Do Multiple People Require a Higher BTU Output?
For every person in the room (above two), you’ll have to add a rough 750 BTUs of power for each individual. If you’re getting a joint unit for a common area in an apartment or dorm of four total inhabitants for, let’s say, a 500 square foot space, you would need 10,000 base BTUs, plus 750 per person after the second, so you would need 11,500 BTUs for that space.
We throw off our body temperature like crazy, especially after coming in from a hot day. We sweat as a way to radiate heat instead of internalizing it, and damaging our organs or brain. As a result, you’re actually throwing off more than your internal body temperature for about four hours after an exercise, or thirty minutes to one hour after entering your room from merely being exposed to high temperatures outside.
Like all the best air conditioners (and wall AC's) it can change your relationship to your home. Where before it may have been the place you wanted to get away from on hot days it can become the place the family seeks out when the mercury rises. It will also allow you to sleep better and to entertain guests in comfort. If you’d like to buy a portable ac for your home any of the above models will serve you well today and for the foreseeable future.
