We looked at dozens of portable air conditioners before settling on 10 to test in our testing lab. These 10, we feel, best represent the industry. To formulate our rankings, we looked at industry-standard efficiency and power ratings while performing in-house testing on maneuverability, convenience and sound output. After our tests ended, we chose the Frigidaire Gallery FGPC1244T1 as the best portable air conditioner. We like its balance of performance, convenience and energy efficiency, though it wasn't the top performer in any of these categories.

Best Overall
The Frigidaire Gallery FGPC1244T1 doesn’t have the best cooling performance in our comparison, but it did better than half of the units we tested. It can handle rooms up to 550 square feet and has a good airflow rating of 200 cubic feet per minute. The Gallery is the second most efficient portable air conditioner we tested. Its energy efficiency ratio of 11 exceeds the average rating of 9.7 among the 10 models in our review.
The Frigidaire Gallery has every feature we looked for, including sleep mode, auto-restart, a programmable timer and a remote control. Most notably, it has oscillating louvers that help to distribute cold air more evenly throughout the room; only two portable air conditioning units we tested have this feature. The noise this machine produces is average, and the fifth-loudest unit we tested. The Frigidaire Gallery is the heaviest portable air conditioner we tested, weighing 78 pounds. We had some difficulty getting it into our lab before taking it out of the box, but the caster wheels made it easier to move afterward. While you probably need two people to move most portable AC units up or down stairs, it's especially true for the Frigidaire Gallery. This unit has an exceptional five-year compressor warranty, the longest in our review.
  • Excellent energy efficiency
  • Good cooling performance

Best Value & Most Efficient
An outstanding energy efficiency ratio (EER) of 11.1 makes the Whynter ARC-12S portable air conditioner the most energy-efficient model we reviewed. This is much higher than the average rating in our comparison, 9.7 EER. Even though it's more efficient than our top pick, the Frigidaire Gallery, it has a similar power output that can accommodate rooms up to 550 square feet. However, the ARC-12S has slightly lower airflow rating of 188 cubic feet per minute, compared with 200 CFM for the Frigidaire Gallery, so its cooling is marginally less effective.
We like that the Whynter ARC-12S is less expensive than the Frigidaire models we tested. It achieves this at the expense of a few convenience features such as oscillating louvers and sleep mode. It's also one of two models we tested without an auto-evaporative system, which means you need to occasionally empty a drip tray so it can function properly. If you can do without those extra features, the ARC-12S is hard to beat. Regarding noise levels, this AC unit puts out 52.5 dB while it's running. This isn't the quietest machine we tested, but it's still a reasonable choice for bedrooms. The Whynter ARC-12S is one of the lighter portable AC units we tested, weighing only 62 pounds. You can move it with the attached wheels like other portable ACs, but it should be easier to carry with two people on stairs than heavier models. The three-year compressor warranty on the ARC-12S is average for the market.
  • Most energy-efficient unit we tested
  • Relatively lightweight
  • Best value for the price
  • No sleep mode
  • Louder than four other models we tested
  • Drip tray fills up occasionally

Most Powerful
The NewAir AC-14100E is extremely powerful. It can cool up to 700 square feet on its own. Although some other portable AC units in our comparison can handle 550-square-foot rooms that are nearly as large, the AC-14100E also has the highest airflow rating of 250 cubic feet per minute.
Despite the power you get with this unit, it only costs around $410, which is slightly cheaper than the industry average of $427. The AC-14100E's extra power also means it has a lower energy efficiency ratio (EER), 9.88, compared to the best portable AC units. For comparison, three other units we tested have EER ratings over 10. This lower energy efficiency means it costs more than average to operate throughout the year. You can offset the operating costs by programming the unit's timer. The AC-14100E is the loudest unit we tested, with a decibel rating of 57. This is almost twice as loud as the 48 dB of the quietest portable AC we tested, which could affect your slumber if you're a light sleeper. At 61.9 pounds, this unit weighs about as much as the average unit we tested. It's fairly easy to move using the unit's wheels, though stairs might be a problem. The AC-14100E has a one-year compressor warranty, the shortest in our comparison.
  • Can handle very large rooms
  • Highest airflow rating in our comparison
  • Surprisingly efficient for its size
  • Loudest unit we tested
  • Above average annual energy costs
  • Compressor warranty lasts just one year

Best Moisture Removal
The Haier HPC12XCR has a higher rate of moisture removal per hour, four pints, than any other portable air conditioner we reviewed. This means it's more suitable for areas where high humidity makes it harder to maintain a comfortable environment.
The HPC12XCR efficiency rating of EER 9.5 is average, but good enough to only use around $90 of electricity per year, $4 cheaper than average. We also like that there's a digital thermostat on top of the unit, so you can set the unit to your desired temperature. This unit weighs 56 pounds, making it lighter than most portable AC units so you can move it between rooms more easily. It has a five-year compressor warranty, which is the longest warranty you can get. With 12,000 Btu, the HPC12XCR is powerful enough for most rooms up 550 square feet. However, its airflow rating of 188 CFM is lower than that of most portable AC units we evaluated, but still as powerful as the Whynter ARC-12S.
  • Removes more moisture per hour than other units
  • Lower airflow than average

Best for Smaller Rooms
At 8,000 Btu, the Sunpentown WA-8070E has lower power than the other portable AC units we reviewed, but this makes it an ideal choice for cooling smaller spaces.
If you live in an apartment or small house, the Sunpentown WA-8070E might be better than a more powerful unit. No matter how efficient a larger unit is, it still adds more to your electric bill than the WA-8070E would, it only costs around $78 per year to run, which is about $15 cheaper than the most efficient unit we looked at, despite a low efficiency rating of EER 8.9. This unit has an airflow rating of 185 CFM, which is enough in smaller rooms. The WA-8070E costs around $318, which is more affordable than most portable AC units. Unfortunately, this unit only has a one-year compressor and appliance warranty, which isn't very competitive with the five-year compressor warranties from Frigidaire, Haier and Honeywell.
  • Excellent for smaller spaces
  • Unsuitable for large rooms

Why Trust Us

We've been testing portable air conditioners, fans, air purifiers and humidifiers since 2014. We apply strict standards for testing each products performance and user-friendliness, and we strive to produce reviews that matter to consumers.

We also consult with experts and guides from organizations such as Energy Star and Energy Saver to find comparative, objective information about the products we test. During our research, we contacted the Association of Home Appliance Manufacturers (AHAM) but didn’t receive a reply, even after multiple attempts to follow up. We did, however, find other helpful AHAM resources, such as blog post on air conditioners and a statement about updated test procedures used to determine a product’s BTU rating.

How We Tested

We tested 10 portable AC models from Amico, Friedrich, Frigidaire, Haier, Honeywell, LG, NewAir, Sunpentown and Whynter. We relied on product specifications and EER ratings to evaluate effectiveness in terms of power and energy efficiency.

We tested the mobility of each portable air conditioner by moving them between rooms. For the most part, we only had trouble moving each product into our test lab while in the shipping packaging. After unpacking the units, it took much less effort to move each one using the built-in wheels. However, if you need to carry any of these units up or down stairs, we suggest caution and having someone assist you as the portable AC units we tested weigh 63 pounds on average.

To test the loudness of each machine, we used a sound meter to take readings while each was running. Using this method, we found that the Amico AP11000 is the quietest unit we tested, at around 48 dB. The loudest portable AC unit we tested is the NewAir AC-14100E, measuring around 57 dB. Although this might look like a small variation, it's not. The typical human ear perceives a doubling in loudness every 10 decibels, so 57 dB is nearly twice as loud as 48 dB. A quieter air conditioner may be best in bedrooms if noise keeps you awake at night.

How Much do Portable Air Conditioners Cost?

On average, portable air conditioners cost around $400, though you can find units as low as $250 and as high as $700. As with other types of air conditioners, you can expect to pay extra for units that have greater power and efficiency than average. You can also expect ongoing costs of around $94 a year on your electricity bill.

What to Look for in a Portable AC Unit

Room Size & Cooling Performance
To select the best portable air conditioner for your needs, it's a good idea to consider room size first. However, labeling a unit's cooling power in terms of optimal room size, it's not uncommon for different manufacturers to use different methodologies, so we followed the room size guide from Energy Star. This uses a product's Btu rating to calculate the maximum room size for a given air conditioner. In general, you should choose a unit that's slightly more powerful than this number, since anything too big or too small might waste energy.

Apart from room size, you can also look over the unit's other power specifications such as power level, air flow, moisture removal and fan modes, all of which determine the effectiveness of a portable air conditioner. However, these aren't as good of a guide as room size. In general, higher values mean higher performance, though the most powerful machines often have lower energy efficiency.

Efficiency Ratings
For efficiency, we looked at each unit's Energy Efficiency Ratio (EER) as provided by the manufacturer. This tells you how much energy it uses when compared with its output power. Among the units we reviewed, the highest EER rating we found is 11.1 while the average rating is 9.84. You can expect to save money on your electric bill if you choose a machine with higher EER ratings. In general, portable AC units aren't as efficient as other types of air conditioners, but they are great for cooling specific areas in your home or apartment.

We also calculated the estimated cost to run a unit eight hours a day for a year using the national average cost of electricity. While this is a practical way to see long-term costs, it differs from the EER because weaker units sometimes cost less to run than more efficient units that are also more powerful.

There are two types of warranties on portable air conditioners: one for the compressor and another for parts. Because the compressor is the most essential component, it should have as long a warranty as possible. The average compressor warranty is three years, but the best units – such as those from Frigidaire, Haier and Honeywell – have five years of warranty coverage. You can expect a minimum compressor warranty of one year. With parts warranties, also called appliance warranties, you can expect one year of coverage from the manufacturers in our comparison.

For safety certifications, we looked for a listing from UL, which requires that the air conditioner meet safety guidelines. Currently, the U.S. Environmental Protection Agency does not give Energy Star qualifications to portable air conditioners, regardless of their energy-efficiency ratings. This is likely because the exhaust hoses on portable air conditioners often interfere with heat dissipation, thus making portable units less energy-efficient than other types of air conditioners.

Convenience features can affect your experience with the portable air conditioner, for better or worse, depending on how you plan to use the machine. The units we tested all have a 24-hour programmable timer, wheels on the bottom and a remote control. However, a few have unique features that differentiate them. These include a sleep mode that adjusts the temperature as you sleep, as well as an auto-restart that turns the machine back on after power outages.

Hose Length
If you have limited space, you may want an air conditioner with a longer exhaust hose. As a byproduct of the cooling process, all portable AC units produce heat that must be vented outside, usually through a nearby window. Units with a hose of 5 feet or longer give you more location flexibility.

Do Portable Air Conditioners Have to be Vented Out a Window?

Air conditioners work by pulling humidity and heat from the air and venting it somewhere else. In a typical window air conditioner or central AC unit, the hot air is released into the outside air near the unit.

If a portable air conditioner worked the same way, it would release as much hot air, if not more, as it would cold air into a room, essentially negating any cooling in the room. Because of this, portable air conditioners use an insulated exhaust hose to transfer waste heat to a nearby window.

No exhaust hose is perfect, so some of the heat leaks into the surrounding room before it leaves the window, which is why portable air conditioners are considered the least efficient type of air conditioner on the market. When it comes to home air conditioners, portability always comes at the cost of energy efficiency.

There are alternatives to portable air conditioners, in case you don’t have a window for ventilation, such as tower fans and portable evaporative coolers, though these don’t cool rooms much compared to a proper air conditioner.

Do You Have to Drain a Portable Air Conditioner?

No. While it’s true that moisture collects in a portable air conditioner, modern units have an automatic evaporation system. This moves water collected from the air inside your home to the other side of the AC unit where it evaporates and gets blown out through the exhaust hose, along with excess heat.

How Long do Portable Air Conditioners Last?

Depending on how well you maintain your portable air conditioner, you can generally get between 5 and 10 years of service. Pay close attention to the warranty on the compressor, as this is a good indicator of how long the unit will last. You can expect portable AC units to last longer than the warranty if you keep up with basic maintenance tasks, such as cleaning filters and winterizing the unit when you put it away for the season. For guidance on how to conduct maintenance, refer to the owner’s manual that comes with your air conditioner.
