The best portable air conditioners

The best portable air conditioners

To keep cool when it’s hot outside, air conditioners help in a big way. While central air conditioners help cool homes, certain places without such a central system — such as a dorm room or recreational trailer — benefit more from a portable air conditioner.

Once the temperature rises, getting work done in your workplace or even just relaxing in your home will be hard to do because you’ll be uncomfortable. A portable air conditioner is a great option when you’re always moving between rooms so you don’t have to rely on static air conditioner units that only cool one room. Most designs are easy to use and can cool a room in a matter of minutes. These leading portable air conditioners in our list can keep the cool air flowing wherever you need it.

BLACK+DECKER Portable Air Conditioner

Best Overall

BLACK + DECKER’s portable air conditioner is a silent yet potent machine that can cool a small room to up to 61-degrees Fahrenheit. The wheels let you easily roll the air conditioner into any room with a window, while the simple installation lets you set it up in a matter of minutes. You can slide out the reusable air filter once it’s caked with dust and grime to clean it up to help maintain your air conditioner’s performance.

There’s also air purification with an included filter and a dehumidifier to help draw water from the air to keep rooms cool and dry — although note that the dehumidifying feature does require a non-permanent window vent, so it won’t work in a fully sealed room. There aren’t any smart features with this model, but it does come with a handy remote that shows you the current temperature and allows for programming, fan adjustments, and more.

Why we love it:

  • Energy-efficient settings
  • Self-evaporating operation
  • Eco-friendly refrigerant

Features to consider

Cooling capacity

Picking the right size for the room or area you want to cool is the most important factor in choosing a portable air conditioner. If you buy a unit that’s too small for your room it will run longer and more often, which wears out appliances prematurely, cost more to operate, and likely never adequately cool the space. Overbuying isn’t a good idea either because larger units are more expensive to run plus, because they cool adjacent air very quickly, shut off prematurely which causes the unit to restart more often than properly-sized appliances.

Portable air conditioner cooling capacity, like window units, are rated in BTUs, (British Thermal Units). BTUs are a standard measure of heat change — in air conditioners, BTUs represent cooling power. Most portable air conditioners include maximum rated room size in feature lists or specifications tables. You’ll find variations in how manufacturers rate room capacities, however. Here’s a quick guide:

  • 5,000 to 6,000 BTU — Small to medium-sized rooms from 100 to 250 square feet and normal ceiling heights
  • 6,500 to 8,000 BTU — Medium to large rooms from 250 to 400 square feet and normal ceiling heights
  • 8,000 to 12,000 BTU –Medium to large rooms from 250 to 400 square feet with high ceilings

Note, however, that rooms on the sunny side of your home, rooms with many windows, rooms with many people, and kitchens will all need more cooling power.

Multipurpose capabilities

Portable air conditioners are primarily used for cooling, but many room-sized units can also function as fans or as dehumidifiers without changing the air temperature. Air conditioners remove humidity while they cool the air, but on temperate rainy days, the ability to switch to a “dry” mode with no cooling is convenient. Similarly, if you just want to air out a room, switching to “fan” mode can do the trick quickly and relatively quietly.

Controls and ease of use

All portable air conditioners should have controls mounted on the unit itself to select modes, desired temperature, and fan speed. Many also come with remote controls so you don’t have to get up to change a setting. 24-hour timers are common, as are automatic restarts after power failures. For the ultimate in portable air conditioner management, look for a unit that connects to your home Wi-Fi network so you can access and control the appliance remotely with an app or via a digital voice assistant such as Amazon Alexa or Google Assistant.


Window air conditioners can be noisy, but, depending on their size and design, portable air conditioners can be even noisier. Window units extend the major loud parts outside the house but portable air conditioners are entirely inside the house. Portable air conditioners don’t consistently list their noise levels in decibels, but if noise will be a factor, look for decibel ratings or noise reduction or mitigation features.
