Most silent portable air conditioners

The most silent portable air conditioner models in the 8000 BTU, 10 000 BTU, and 12000 BTU and above ranges have less than 56 dB of noise.

The fact that portable air conditioners are so accessible, and movable makes them quite convenient, but the noise levels can be inconvenient, and maintenance can take a lot of effort with these units.

This is why many portable air conditioner manufacturers have developed silent models. There are silent models that have below 56 dB in varying BTU ranges.

The convenience of portable air conditioners

Portable air conditioner models are popular because they are a convenient way to cool down rooms ranging from as small as 150 square feet to larger rooms of up to 500 square feet.

They are also popular because these portable air conditioners are easy to install and use and can be moved from one room to another.

However, portable air conditioners do need to be drained and vented, which can make them more maintenance-heavy and inconvenient to use than other types of air conditioner models.

One of the other factors that can be inconvenient about a portable air conditioner is the fact that these units can be extremely noisy.

Part of what makes portable air conditioners so unique and flexible is that they are contained in a single unit. This makes them ideal for apartment living and renter-friendly, since they do not need to be permanently installed in your space.

However, this setup does mean that the fan motor and compressor are not hidden away in an outside unit or in your house’s ductwork, which makes portable air conditioners much louder to operate than other central air and mini-split units.

To counteract this, many manufacturers have started focusing on making their portable air conditioner models as quiet as possible, and some even introduced ultra-quiet models that produce less than 50 decibels (dB) of noise.

General guidelines for finding a quiet portable air conditioning unit are as follows:

Decibel level (in dB) Description
Over 80 dB Too loud for household usage
70 dB Loud household appliances
60 dB General noise level for appliances
50 dB Fairly quiet for a portable air conditioner
Under 50 dB Ultra-quiet portable air conditioner models

However, with such a wide variety of portable air conditioner models available, it is important to find not only the quietest one, but also the model that is the appropriate size for your space. Fortunately, there are quiet options in every BTU category.
