Finding a quiet window mounted air conditioner can be a challenge. Mainly since the noisy components, the compressor and fan, are located directly inside the packaged unit.
Since the compressor is located in the unit and not outside away from the home some degree of noise will always be present.
With that said there are some window air conditioners that have less noisy compressors than others.
The best way to judge how noisy a window air conditioners will be, is to read real reviews from real people online.
Keep in mind to get a truly quiet unit there are other ways that are affordable such as mini split systems which separate the compressor outside and then feed lines into a home that circulates refrigerant to a blower motor. Split systems require more effort and skill to set up but are not as expensive as traditional central air conditioning systems used in homes.
Here are the top units we have found that make the least amount of noise.
As always be sure to read reviews on Amazon, forums, or elsewhere to be sure a unit is the right pick for you.

The cross flow fan technology also makes the fan run smother and make less noise than conventional fans.
