In many parts of the country, living without air conditioning is an uncomfortable proposition to say the least. Fortunately, even those without central air or a window unit can keep cool with a portable air conditioner.

Many different companies make portable air conditioners, and not all of them are created equal. To find the best portable air conditioner for your needs, you’ll need to look at a number of different criteria in determining what will work best for your situation.

Read on to learn all you need to know about the portable air conditioners on the market and update yourself on the information you need to choose the best air conditioner for you and your family.

How We Picked the Best Portable Air Conditioners


While most portable air conditioners seem similar at first glance, the big differences are between their features and capabilities. To make our selections, we looked at a number of different criteria that helped us pick the few from the many.

  • Reach: The size of room a portable air conditioner can cool is one of the most important considerations. You can’t skimp and get a unit that is designed to cool a 150-square-foot room and expect it to cool a 500-square-foot living room.
  • Features: This category really sets the best portable air conditioners apart from the rest. Units that have easy-to-use controls, multiple settings, and are simple to set up and operate got higher marks than those that didn’t display those traits.
  • Value: We considered a price range to suit any budget, so you can be sure to get all the cooling power whether you want a premium pick or an affordable option.

Things to Consider Before Buying a Portable Air Conditioner

Before buying a portable air conditioner, first determine exactly what your cooling needs are. If you’re trying to cool an entire house, you may need to look into central air, or possibly a window unit or two. But if you’re just trying to cool a small to medium-sized area, a portable air conditioner might be just what you need.


BTUs or “British Thermal Units” measure the amount of energy your air conditioner requires to take heat out of the air over the course of an hour. Higher BTU’s will route more energy to the task at hand, meaning more cooling power but higher energy bills. Look for air conditioners with about 20 BTUs for every square foot you intend to cool.


Above all other considerations, determine how much space you plan to cool. Figure out the square footage you intend to cool and use that as your starting point.


Another consideration is size. Unless you’re living in the desert, you may need to store your air conditioner for the off season. Smaller units are easier to move around and easier to store when not in use. So looking for a smaller unit that will cool the same amount of space is a good idea.


Lastly, consider price. If you can find a very small, very powerful unit that will cool the amount of space where you are intending to use it, you’re on the right track. Take the short list of portable air conditioners that meet your criteria and compare them to your budget, that way, you’ll know you chose the best portable air conditioner for you.


Q: Are portable air conditioners effective?

They can be effective depending on the amount of space you want to cool. If you have a fairly small space, a portable air conditioner is a great and cost-effective way to cool down. But a solo portable air conditioner is not equipped to cool down an entire house, so keep your space in mind. 

Q: Can a portable AC cool a living room?

That depends on the size of the living room. If you have a powerful portable air conditioner that will cool off a room measuring 500 square feet and only a 300-square-foot living room, you’ll be cool in no time. But if your room is much larger than the capacity of your portable air conditioner you might be disappointed—and probably warmer than you’d like to be.

Q: Is a portable air conditioner better than a window unit?

Typically, window units are both more energy efficient, and cool a room better than a portable air conditioner could. However, if budget is a big concern, and you are trying to cool a fairly small room, or if you want to take your air conditioner with you on the road, a portable air conditioner might be your best choice.

Final Thoughts

There are a lot of good portable air conditioners on the market. Whether you need a full force option to keep your space cool like the Whynter Dual Hose, or a desk-friendly pick like the Air Choice Mini for stuffy days at the office, there’s a portable air conditioner for you. If you don’t want to install hefty and expensive full AC units, a portable option can be a great alternative for keeping cool.
