Top 10 Best Ultra Quiet Window Air Conditioners

Best Ultra Quiet Window Air Conditioner

Updated: 6/20

Finding the best ultra quiet window ac can be difficult. Most models don’t list their decibel range (aka: noise level) and there’s a wide ranges of prices from $150 to $500 (or even more!)

Depending on the power/speed setting, noise levels can reach 60+ decibels which is noticeably loud.

Average noise is 54-58 dBs.

Since many of the ultra quiet window air conditioners are not affordable, I created a shortlist of the best quiet window ac units available online.

Window AC unit prices on my list range, $179 – $429.
