The 10 Quietest Portable Air Conditioners

Shopping for the quietest portable air conditioners is a particularly difficult task, but not because there are hundreds of options to choose from. What makes it difficult is that there is no truly reliable way to judge the noise level unless you do a hands-on test. Sure, some manufacturers list the noise level of their products, but we all know that officially listed specs are not always on-point and are sometimes buffed up to make products more appealing to consumers.

In this guide, we have compiled the 10 quietest portable air conditioners on the market. While not exactly whisper-quiet, all products included here are relatively quieter than other portable air conditioning units, based on both customer feedback and the manufacturer-listed noise level.

Air Conditioner Noise Levels

One of the best ways to check the noise level of portable air conditioners is to read feedback or reviews of customers. It’s not exactly 100 percent reliable, as not everyone has the same standards when it comes to noise level, but it’s better than simply relying on the official specs.

If you think that sounds like a very time-consuming task, that’s because it is, especially since there are also other important factors to consider when shopping for portable air conditioners – like the cooling power or capacity, usually listed in British Thermal Unit (BTU), and the room coverage. But the good news is that we already did the hard work for you with this review guide.
