What to Look for in the Best Portable Air Conditioners

There are a ton of different options when it comes to choosing the best portable air conditioner for your space. You’ll have to look at the size, features, and — most noteworthy — the cooling capabilities of the unit you’re thinking about installing.

How do portable air conditioners measure power?

Powering Portable AC Units

Btu (British thermal unit) is the measurement of power for most types of air conditioners. The Btu measurement indicates how much heat the air conditioner can remove from a room. Generally speaking, the higher the Btu, the more powerful the AC.

We’ve put together a few recommendations for choosing the right portable air conditioner for your space. Keep in mind that these are base stats, and you may want to go a little higher for some wiggle room (and be sure to keep in mind ceiling height). We don’t recommend going any lower than 6,000 Btu unless it’s for an extremely small area because even the best 5,000 btu portable air conditioners often aren’t very effective at cooling spaces over 100 square feet. 

Here’s a rough comparison guide for Btu and square feet.

Btu Sizes:

  • 6,000 Btu will cover roughly 150-200 sq/ft
  • 8,000 Btu will cover roughly 300-350 sq/ft
  • 10,000 Btu will cover roughly 400-450 sq/ft
  • 12,000 Btu will cover roughly 450-550 sq/ft
  • 14,000 Btu will cover roughly 550-700 sq/ft

However, suppose you’re interested in something more powerful, like the best 18,000 Btu portable air conditioner. In that case, you’ll probably need to search for industrial portable air conditioners or consider a more permanent solution to cool your air. 

Aside from the actual power of your unit, it would help if you also considered energy efficiency. Low Btu units usually take up less energy. In contrast, some high powered ACs are built to be easy on your wallet (and the environment). Energy Star certification is always a good starting point.

Noise can play a huge factor as well. Always check out the reviews to make sure that the noise level is tolerable.

What is a Portable Air Conditioner?

Now that we’ve had a look at the best portable air conditioners of this year, let’s talk a little more about the technical details behind these units.

In short, a portable air conditioner is a detached and self-contained air cooler that is perfect for cooling areas of varying sizes. But how does it work?

Most residential models attach to your window via a hose. This hose collects the air from outside and runs it through a conditioning process.

Components

The conditioning process, or refrigeration cycle, requires several components to function.

  • condensing coil
  • expansion valve
  • evaporator coil
  • compressor

With all these components working together in unison, the air conditioner’s internal chamber gets icy cold as the air starts to circulate inside. Once the air is sufficiently chilled, the AC unit pumps it out into your room.

It only takes a few minutes for small rooms to start to cool down. Plus, many ACs will automatically maintain the atmosphere once they reach the perfect temperature!

How to Use a Portable Air Conditioner

One of the main selling points of a portable air conditioner is that it moves around from room to room without much hassle. Compared to other types of coolers, such as window ACs, this gives you much more freedom and flexibility.

Portable air conditioners work wonders for bedrooms, offices, living rooms, and other spaces around the house. However, if you want the best portable air conditioner for a garage, keep in mind that these units work more efficiently in insulated spaces. And, you’ll still need a way to vent the unit for it to be effective.

Setting up portable air conditioning units is a breeze due to the simple installation process of attaching the hose exhaust to the window opening. If you follow the instructions correctly, it will most likely only take a few minutes to get up and running. 

Plus, most portable air conditioners will cool your room in just a few minutes! That’s hard to beat.

We’ve looked at many portable air conditioners, all with varying specifications and features. But the question remains: which is best?

The truth is, there isn’t any best portable room air conditioner. You have to consider all your requirements when making a final decision. One household may do well with an 8,000 Btu unit, while the mansion at the top of the hill might well need a 20,000 Btu behemoth!

Finally, it’s about finding what works for you.

The best portable air conditioner that meets your needs is out there! Do your research, shop around, and above all — remember to stay cool!
