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.
Prices on my list range, $179 – $429.
