With the warmest days upon us, our team of AC experts has found the best options to keep your home cool. While the cooling rate is a large portion of our overall scoring, we also measured energy efficiency, noise level, portability, and installation difficulty before making our recommendations.
The Midea U-Shaped MAW08V1QWT is the best overall air conditioner for most households. It offers efficient cooling while keeping energy usage down, and still allows your window to be fully functional. If you need a machine you can move from room to room depending on the day, the Whynter ARC-1230WN is our favorite portable AC option.
Over the years, we've tested plenty of home appliances. In addition to an AC, you can keep the air moving with a top-notch fan. If you live in a dry climate, you might be interested in adding some moisture to the air with one of these humidifiers. Whatever your needs may be, our team has likely spent hundreds of hours extensively researching and testing it.
Editors Note: We updated this review on May 28, 2025, to include more options for portable air conditioners and provide more up-to-date information on our award recommendations.
Who It Is Best For: This highly efficient air conditioner is ideal for those who need to keep small-to-medium spaces cool without spending big on their energy bill. Inverter technology means that this unit uses less electricity than others we tested, and its nifty U-shaped design puts its loudest parts on the window's exterior, which could make a big difference if you work from home or like to watch TV in an uber-quiet setting.
Why We Love It: In addition to its energy and noise-saving qualities noted above, the Midea comes with both a traditional remote and a mobile app, plus it's compatible with Google Assistant and Amazon Alexa. It's also designed so that the window it's installed into remains fully functional, so you can safely vent your space while cooking or during cooler evenings.
Should You Buy It? Our team of testers found the Midea U-Shaped MAW08V1QWT to be the best window air conditioner for most people. It's energy efficient, decently quiet, and app-compatible. Installation can be a bit tricky, but if could be worth it if you're after an effective window unit.
Who It Is Best For: The Whynter ARC-1230WN is a stand-out portable AC for larger rooms. Its 12,000 BTU rating means that it can provide powerful cooling (it was able to chill our testing facility's room by nearly 12 degrees in just one hour), and its inverter technology helps the unit remain decently energy efficient. The window mount is a bit larger than average, so you'll just want to ensure your window is big enough. This was also among the quietest units we tried and came with an excellent child lock, so it's a great pick for those with small kiddos.
Why We Love It: In addition to its awesome inverter technology, we loved how full-featured the Whynter ARC-1230WN was. It came equipped with multiple cooling modes, a child lock, a traditional remote, and a mobile app.
Should You Buy It? The Whynter ARC-1230WN is amazing at cooling big spaces quickly and efficiently. It's a bit heavy to tote around from room to room, but manageable enough if you're only storing it or moving it at the end of the season. If you have high ceilings, an open-plan living room, or a large square footage that you need to stay chilly this summer, we highly recommend this machine.
Who It Is Best For: At just 6,000 BTU, the LG LW6017R held its own against some of the most powerful 12,000 BTU machines. For spaces up to 260 square feet, it'll have no trouble keeping things cool, even though it doesn't have the inverter technology of pricier models. Though it produces more noise than many models we tested, we feel that the energy efficiency and cooling power of the LG LW6017R make it the best pick for a window AC if you're on a budget.
Why We Love It: In addition to its powerful cooling performance on standard settings, this LG air conditioner has an 'eco' mode that works with a range of fan speeds. This straightforward and convenient unit can also be controlled manually or via remote control. A well-lit screen displays the temperature and fan speed. Last but not least, the LG manages to do all of this at a modest price point.
Should You Buy It? The LG LW6017R manages to hit that elusive sweet spot between cooling performance, ease of use, and wallet-friendly price point. Though it's a bit noisy when compared to several premium units we tested, we feel that it's the top choice if you're on a budget and seeking to cool a room of 260 square feet or less.
Who It Is Best For: The GE AHEC05AC boasts large, easy-to-use knobs and manages to pair price and performance perfectly. As such, this is a great choice for shoppers who are on a strict budget who only need to cool a small space of 150 square feet or less, like a bedroom, den, or office.
Why We Love It: Even though it's only rated at 5,000 BTUs, this unit cooled off our 140-square-foot test room in no time, dropping the temperature by 8.8 degrees in just an hour. Not only that, it does so while keeping the energy bill down. Even on the highest mode, it consumed less energy than the average window unit. It was also more lightweight than most and pretty easy to install.
Should You Buy It? One of our few gripes about this unit is that it's a bit noisier than many window ACs we tested. If you don't mind working and relaxing with a bit of white noise in the background, we think that this wallet-friendly GE air conditioner is a fantastic choice for those who need to cool a smaller room this summer while sticking to their strict budget.
Who It Is Best For: The SereneLife SLPAC10 was not only affordable, but it was also one of the lightest portable air conditioners that we tested. This makes it a top choice for people who might need to move it around on high-pile carpet or switch it from room to room, depending on the day. Set up only took our tester five minutes, and when it's ready to store for the winter, the SereneLife's window kit and hose quickly disassemble.
Why We Love It: A 10,000 BTU rating is pretty great for a budget-friendly AC. In addition to not breaking the bank, the SereneLife includes a convenient remote that gives control over the fan speed, temperature settings, vent swing, and adjustable timers. Though the unit is on the louder side, it wasn't horribly distracting and could easily be shrugged off as white noise.
Should You Buy It? Of all the portable AC units we've tested, the SereneLife SLPAC10 is the easiest to set up. Its 10,000 BTUs of cooling prowess make it a great machine for chilling small- to medium-sized rooms, and it isn't overly loud. We feel that this is the best portable air conditioner for those on a budget who aren't trying to cool down a massive space with high ceilings.
BTU: 10,000 | Hose Configuration: Single | App: No
Who It Is Best For: If you're seeking a quiet, powerful window air conditioner that can cool down a larger room with ease, the Midea U-Shaped MAW12V1QWT is a winner. Its noise management is thanks to its U-shaped design, housing most of the loud mechanical parts outside the window, plus it offers a wide variety of modes and settings, which can all be accessed by its handy remote or smartphone app.
Why We Love It: Overall, we were impressed with the Midea U-Shaped. This powerful 12,000 BTU window AC can tackle just about any space, lowering the temp in our test room by roughly 12 degrees in an hour, all while staying relatively quiet. In addition, the AC is controllable through Google Assistant and Amazon Alexa, making it an excellent pick for those with a smart home setup.
Should You Buy It? If you've got high ceilings, a big studio, or an open-plan home that needs powerful cooling throughout the sweltering days of summer, you can't go wrong with the Midea U-Shaped MAW12V1QWT. It's relatively noise-free, sports a functional child lock, and is compatible with both a mobile app and numerous smart home setups.
Who It Is Best For: For the non-noise-sensitive who need a powerful window AC to quickly cool down a large space, like a garage, the Frigidaire FHWC124WB1 gets the job done. In just an hour, this 12,000 BTU air conditioner managed to cool down our testing room by 14 degrees. Most options can be controlled through its remote, though timers and the child lock need to be set directly on the machine.
Why We Love It: Even though this window AC was significantly louder than many we tested, this is an amazingly powerful machine that's capable of cooling big spaces—like a garage, a studio, or a home gym—quickly and efficiently. The airflow can also be adjusted horizontally and vertically to find the perfect angle for your cooling sweet spot.
Should You Buy It? Despite how well it cools large spaces, the Frigidaire FHWC124WB1 isn't the machine you want in your living room or office. It's also large and a bit bulky. Nevertheless, this is a great and powerful air conditioning unit for a home gym or garage.
Who It Is Best For: If you're noise-sensitive, work from home, or have frequently napping little ones in your space, the LG LP1022FVSM is worth your consideration. This was also one of the easiest models to move from room to room, thanks to its onboard storage for the hose and window kit, making it great for anyone who needs to frequently move their AC.
Why We Love It: Our SPL meter measured only 56 decibels on this unit, making it the quietest we tried by far. The nearly silent 14,000 BTU machine is more than adequate for keeping most average- and large-sized rooms cold when it's scorching outside. The LG also includes a wireless remote and can be controlled through its accompanying mobile app. Within the app, you'll be able to monitor your energy use, air filter status, and run smart diagnostics remotely.
Should You Buy It? If you need a powerful air conditioner that's nearly silent, even if you're standing a scant four feet from its fan, the LG is our top pick. It's a premium-quality AC that packs in 14,000 BTUs of cooling power, and it is easy to adjust, via remote or smartphone app. It's also got handy onboard storage for its hose and window kit, so packing it up to store at the end of the season is a cinch.

How We Tested
We've searched high and low to find the best air conditioners out there to keep you cool all summer long. Our search started with an in-depth look at the market. We then purchased the most promising models to evaluate back-to-back in a controlled, objective space. We set up standardized trials to determine which ACs could cool off our hot, summer-simulated testing rooms. During this period, we measured the air conditioner's energy efficiency and noted any additional features. We also determined how easy it was to install and uninstall each unit, and tested for noise and portability, too. With all this in mind, we were able to find the best products on the market to present to you. For more information, see our articles on how we tested portable AC units and how we tested window AC units.
Portable ACs can be stored for the cooler seasons, so we noted how hard it was to carry them upstairs.

How to Pick the Best Air Conditioner
With temperatures hitting record highs every year, the need to stay cool is becoming more and more prevalent. While central AC might be common in houses in warmer areas, this hasn't been the standard for colder climates until recently. Installing central AC isn't always practical or economical, and the need for a quick fix for those sweltering summer days is crucial. This is where options like window units and portable ACs come in handy. These units are comparatively inexpensive and easy to self-install.
We've tested over 30 air conditioners since 2018 to help you find the best.

Window Air Conditioners
As the name suggests, a window unit sits in the window. They are designed to fit in both horizontally and vertically sliding windows, and they use a thick material that accordions out across the gap to keep the room insulated. Often, they require some sort of exterior bracket to hold them in place. Although it takes a bit of effort, installation isn't too much of a headache and can be done with one or two people.
REASONS TO BUY
No floor space taken
Typically quieter as the compressor is outside
Tends to be cheaper
REASONS TO AVOID
Requires installation
Less mobile - typically stays in place
Obstructs window view and sunlight
Depending on where you live, you might choose to keep your window AC installed year-round, but for climates with cold winter months, we recommend removing the unit and storing it to keep your room better insulated. That said, installing and uninstalling a window unit every year isn't as quick and painless as installing a portable AC. Additionally, you essentially lose the function of that window while the heavy window AC is in place. The chart below summarizes the overall performance scores from our window air conditioner review.

Portable Air Conditioners
Portable air conditioners are freestanding units that can be rolled around from room to room. These units funnel out warm air via a hose that is attached to a window bracket. Installation is generally a breeze, with the most complicated step being the initial bracket setup, which makes winter storage quite simple. Some units use foam to help them seal properly in the window space, while others simply clip into the window pane. Unlike a window AC, the window remains functional while the AC is installed, and you won't have a bulky box sitting on the exterior of your home. While they are less conspicuous from the outside, they do take up interior floor space.
REASONS TO BUY
Easy to install
Renter friendly
Can be moved from room to room
REASONS TO AVOID
Takes up floor space
Compressor located inside the room, so it's noisier
Still requires a window to vent hot air out
Portable air conditioners vary in weight, ranging from 45 to 80 pounds. If you choose a unit on the heavier side, it can make transporting them from space to space challenging, especially if stairs or high-pile carpets are involved. However, most units have wheels on the bottom that roll smoothly on hard surfaces. Our testing team made sure to find the ideal portable air conditioners through hands-on testing. The chart below represents the overall performance comparison from our evaluation.

How Many BTUs Do You Need?
BTU, which stands for British Thermal Unit, is a measurement that indicates the amount of hot air an AC can remove from a space. While its application goes slightly beyond measuring room cooling power, this is at least what it means regarding ACs. To put it simply, a larger BTU rating is needed for larger rooms. Likewise, smaller rooms can get away with an AC with a lower BTU. Most manufacturers indicate the square footage of a room best suited for the specific air conditioner, though we found this to vary throughout our testing.
BTU Ranges for Room Size
Room Size
Recommended BTUs
Up to 200 sq. ft.
6,000-8,000 BTUs
200-300 sq. ft.
8,000-10,000 BTUs
300-500 sq. ft.
10,000-14,000 BTUs
500+ sq. ft.
14,000+ BTUs
As a general guideline, 6,000-8,000 BTU machines work best in rooms up to 200 square feet, while 10,000 BTU machines are suited for rooms up to 300 square feet, and anything over a 12,000 BTU unit will be best for 300 square feet and above. In addition to the size, you'll want to consider other environmental factors in the room you plan on cooling down. If there are additional sources of heat, like sunny, south-facing windows or an oven, you'll want to up the BTU to compensate.

Consider Energy Efficiency
We measure each unit's energy consumption with two main concerns in mind: your wallet and the environment. Some of the most efficient models are more expensive upfront, but the cost to run them each month is lower because they use less electricity. With enough time, the lower energy bill will offset the original price of the unit, sometimes dramatically. Plus, these efficient models are kinder to the environment, so you can comfortably leave the AC on throughout the hottest summer days without too much thought on how it'll impact your wallet or the climate.
According to our watt meter, Black+Decker BPACT08WT is one of the most efficient portable ACs around.

Window units tend to be more energy-efficient than portable models. This is because they house their hot compressors outside of the building rather than pumping out hot air through a hose. If you are searching for the most efficient models, look for ACs with inverter technology. This adjusts the speed of the motor based on the ambient temperature. Non-inverter models cycle through powering the motor fully on and off, which can be far more energy-consuming.
Window units house the heat-producing mechanical parts on the outside of the house.

Extra Features to Consider
Most appliances today offer “smart” capabilities, and air conditioner manufacturers are certainly hopping on this trend. Many of the portable and window models we tested have accompanying mobile apps that allow you to set timers, access child locks, and more, depending on the machine. The range of features often seen on modern ACs include:
Compatibility with Alexa, Google Assistant, and more
If you aren't into smart tech, most traditional models come with a physical remote and basic programmable options.
Not into turning your space into a smart home? No worries, most come with traditional remotes.

Conclusion
Being uncomfortably warm in your own home is a problem that no one wants to have, and not all houses have central air conditioning. Most people aren't looking to start a major renovation to install central AC either, so it's important to have an affordable and headache-free alternative. This review of the best window and portable air conditioners should do the trick to keep you cool all summer long. Many sites out there provide you with seemingly complicated ratings, and we understand how overwhelming it can be to select an AC. That's why we did all the testing for you, putting it together in this expert-backed, easy to read article. We hope this review helps you find the perfect AC for your space.
