Top 10 Best Quiet Window Air Conditioner 2019

Window Air Conditioner Unit

Ultra Quieter Window Air Conditioner Review.

Finding a quiet window air conditioner can be difficult.

Many units don’t 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 aren’t affordable for most consumers, my review factors in price, BTU power, and noise level (dB or dBa).

 Top #1 Pick: Haier ESAQ406P Serenity Series

Haier Serenity Window Air Conditioner

Check Price Button

The Haier ESAQ406P Serenity is quickly becoming most popular quiet window air conditioner on Amazon.

It’s 9-10 decibels quieter than other window-mounted units — great as a bedroom AC!

If you’re a light sleeper, this is the one for you!

AC Power: 6050 BTU

Noise Level: 42 – 53 dB

Room Size: 150 – 250 sq. ft.

To reduce noise, the Haier Serenity AC uses a compressor blanket — it also has different mechanisms to control air flow, making it quieter and energy efficient.

Cooling power is only 6000 BTU, but it includes a dual motor for fast cooling.

Haier ESAQ406P also features a built-in dehumidifier and LED remote control.

It’s expensive for a 6000 BTU unit, but I think it’s the best quiet window air conditioner that’s somewhat affordable.

Lots of happy buyer reviews too.

#2.) LG Window Air Conditioner and Heater

The LG 7,500 115V window-mounted unit is a favorite for bedrooms.

It also has a good energy efficiency ratio (EER) of 11.2.

Reviews say heating is nice in the summer, but mostly love its ability to run quietly at night.

#3.) LG Dual Inverter Window AC
