When it comes to portable air conditioners, we really like the Haier HPC12XCR from Elite. It’s designed for smaller rooms, and its 12,000 BTU will be strong enough to cool a 350 square foot area. It’s a lot easier to carry around than larger air conditioners. It’s portable, runs silently, and can be placed almost anywhere.

The HPC12XCR won’t require you to run a long cord to your nearest outlet. You can instead run it from your car’s battery using the car adapter. This portability allows you to set it up in places that don’t have access to the traditional AC outlets.

When thinking about air conditioners, we gave some thought to size, portability, and alternatives for the bedroom. We wanted to find something small enough to fit under the bedside table of the typical hotel room, which limited us to about 12,000 or less BTU.

Frequently Asked Questions (FAQ)

How can I make my portable air conditioner quieter?

If you’re purchasing a fan for the bedroom in an effort to keep your partner or roommate happy, then a portable air conditioner is not the right choice.

Portable air conditioner units are not suitable for rooms with high ceilings, so you’ll need to make sure it doesn’t hang too low if you have a vaulted ceiling.

Rather than having multiple long extension cords running into the room, you’ll need to find one that has several outlets on it, and an extension cord that can reach to the nearest outlet. Even if you do this though, the noise probably won’t be reduced that much.

The most effective way to decrease noise is having a smaller portable air conditioner unit. Most small units don’t have heat exchangers, so will therefore be much quieter.

Are there any quiet portable air conditioners?

Yes! The nearly silent models can pump out cool air but be barely audible while doing it. Often the fan can barely be heard at all, even at the highest settings. These units are recommended if you share living quarters with a significant other who wants to sleep while you run an air conditioner.

Some manufacturers have begun to add vented window kits to their units, which allow them to be used without having to install it in a window.

Why are portable air conditioners so noisy?

Compared to room air conditioners, there are several reasons why portable air conditioners are the noisiest. The main reason is because they are not as effective. When a space needs to cool, it has to get through several passes of air. This is why you see long blue hoses with most portable units. The more powerful room air conditioners don’t need this because of a more efficient and effective cooling process.

What happens with a household portable air conditioner is it will emit air and cool the air, which then comes out at a slightly warm temperature. These warm-ass air blasts will then be circulated and cooled again and then blasted another time. This will happen several times. This is why the room gets cold, not because of how portable they are, but because of the warm air blasts.

Conclusion

When looking for a portable air conditioner, you’ll have two options. You can buy a window mounted air conditioner unit that sits in your window, or you can get a portable air conditioner unit that sits on the floor. The window mounted units can be expensive and might not cool your room as efficiently.

And, if you’re like me, you might not want to block access to the window. This is why if you’re looking for an inexpensive alternative, a portable air conditioner is an excellent choice.
