Top 10 Best Quiet Window Air Conditioner

Window Air Conditioner Unit

Best Quiet Window Air Conditioner Reviews.

Finding a quiet window air conditioner can be difficult.

Many units do not list a decibel range and pricing can fluctuate.

Depending on speed/power settings the average noise level appears to be 55-58 decibels.

Since many of the quietest window air conditioners ar too expensive for most consumers, my review factors in price, BTU power, and noise level (dB or dBa) — below are my picks for quiet window acs for home.

Window air conditioner prices range, $149 – $499.
