What can you expect from the noise level of a portable air conditioner?

Unlike a split air conditioner, a portable air conditioner has everything in one casing. This means the compressor of the air conditioning, which is responsible for the noise, is built into the casing. This causes a lot of noise. With a split air conditioner, the compressor hangs outside, so it's not as loud.

The temperature outside has a big impact on the noise level of the air conditioner. The more extreme the temperatures, the harder the air conditioner has to work. If the air conditioner has to work harder, it also produces more noise. Always check if you can make it easier on the air conditioner. Keep your curtains closed or use a window sealing set to keep out hot air, for example. The settings of the air conditioner also have an impact on the noise level. If you set the air conditioner to the highest air flow speed, it produces more noise than in night mode, for example.

Let's get right to it: no, there aren't any portable air conditioners that are completely silent. You'll always hear noise. But some air conditioners are louder than others. It's important to know is that a difference of a few decibels can make a big difference in the intensity of the sound. Want to reduce the noise of the air conditioner? Set the air conditioner to night mode. An air conditioner produces less noise in night mode because it works at a lower capacity.
