After reviewing the top models on the market, we found that the quietest best-performing unit is the Haier HPC12XCR, which is also our recommendation for the top small portable AC.Because of its small size, it keeps noise to a minimum, at just 50 decibels, but with 12,000 BTUs of cooling power, it’s strong enough to keep your room consistently cool.
There are some steps you can take to reduce the noise your portable AC generates. First, before you purchase a portable AC, check the decibel rating. You want to look for a unit with a decibel rating in the 48-55 dB range. Next, most portable AC’s have multiple fan speeds. The higher the fan speed, the noisier the unit will be.

The noise difference in this case doesn’t seem too impressive though. I guess it also depends on the length of the hose and the distance. Also, how well the hose is attached and tightened on the intake valve. 2. Install a muffler on the intake component. This is a fast and easy way to further reduce the noise …
