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
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.
The LG 7,500 115V window-mounted unit is a favorite for bedrooms.
As an all year-round AC it offers quiet operation and supplemental heating (during colder months).
Multiple units — all are much quieter in operation compared to similar BTU units.
|LG Window AC||Cooling Power||Room Size||Noise Level|
|LW8016HR||7500 BTU||320 sq. ft.||≤ 49 decibels|
|LW1216HR||12000 BTU||550 sq. ft.||≤ 51 decibels|
|LW1816HR||18000 BTU||1000 sq. ft.||≤ 61 decibels|
|LW2416HR||23000 BTU||1420 sq. ft.||≤ 64 decibels|
The LG 7500 BTU window air conditioner (LW8016HR) is the most popular for bedrooms.
Buyers say it cools bedrooms quickly — some like to pre-cool rooms 10-15 mins beforehand.
Room size: 320 sq. ft.
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.
Very good buyer ratings online.
The LG Dual Inverter window air conditioner is not your typical window-mounted AC.
It’s designed w/ twin rotors and includes a specialized compressor to reduce noise — basically two ACs in a single unit.
Rooms: 1000 sq. ft.
Noise Level: 44 dB
It offers ultra-quiet, “LoDecibel” operation using a brushless DC electric motor. It’s naturally quieter and requires less energy (compared to other 18000 BTU units).
As an energy efficient window AC, you can expect a 25% reduction in your monthly bill.
LG Dual Inverter window unit is meant for larger rooms, but versatile enough for bedrooms or home offices.
Also available in two other sizes:
|LG Dual Inverter||Cooling Power||Room Size|
|LW1517IVSM||14,000 BTU||500 – 800 sq. ft.|
|LW1817IVSM||18,000 BTU||800 – 1,000 sq. ft.|
|LW2217IVSM||22,000 BTU||1,000 – 1,300 sq. ft.|
The downside is the price – it’s not cheap. It’d be higher on my list if it were more affordable.
It’s a little new, but so far happy buyer reviews.
The Frigidaire Energy Star is an affordable, quiet window air conditioner.
It has some mixed reviews online, but the majority of buyers say it’s very quiet and good at maintaining cooler temps for long hours.

You can also run the Frigidaire window air conditioner on “Sleep Mode” for even lower noise levels.
Each model is Energy Star qualified and operates w/ lower voltage.
The negative buyer reviews say that it gets loud after some time — this is likely because they didn’t clean the filters.
Frigidaire Energy Star window AC includes easy-wash filters, making it a fixable issue.
Overall it’s an extremely quiet window air conditioner that’s affordable.
The Frigidaire FFRA0511R1 is a smaller AC, but offers a new “Sleep Mode” and is affordably priced.
Designed for rooms up to 150 sq. ft., it’s good for bedrooms — many buyers appear to be city dwellers.
AC Power: 5000 BTU
Rooms Size: 150 sq. ft.
Noise Level: 51.3 – 56.5 decibels
For night you can select the “Sleep Mode” on the remote control.
It’s overall fairly quiet, but by selecting this setting it will operate below 50 decibels lets you select “Sleep Mode”
They also offer 3 fan speeds and multi-directional air — the remote control lets you toggle the air flow direction using rotating louvers at the top of the AC.
Lots of positive reviews and affordable price.
The LG Energy Star unit is the perfect combination for energy efficiency and quiet operation.

|LW1217ERSM||12,000 BTU||550 sq. ft.||≤ 52 decibels|
Buyers love the WiFi window air conditioners — they’re not much more expensive and they let you control all settings using your smart phone.
As bedroom units, the mobile app is a nice luxury in peak summer months.
Mobile app controls:
- Turn on/off (remotely)
- Set desired room temps
- Switch mode: AC, fan, or dehumidify
- Control speed/power settings
LG Energy Star would be my personal choice.
They’re more expensive, but the WiFi “smart” functionality and quiet operation make it worth the money.
The Danby window air conditioner with silencer technology is a newer model — very few reviews online.
It should be more popular than it is given its affordable price and super quiet operation.
Available in 2 sizes:
DAC060BHUWDB: 6000 BTU (250 sq. ft.)
DAC080BHUWDB: 8000 BTU (350 sq. ft.)

It’s also an energy efficient window air conditioner unit — it’s Energy Star rated and includes an “Energy Saver” mode.
Energy Saver will automatically switch from AC to fan mode, while maintaining room temp.
Also includes Sleep Mode for even quieter operation.
Not many reviews yet, but def one of the quietest window air conditioner units available in 2019.

Easily connect directly to your home WiFi — once ready, you can change all settings and set a desired temperature.

Frigidaire window air conditioner units are Energy Star rated for efficiency and will save you money longterm — energy efficiency also helps reduce noise when maintaining cooler temps.

Bit expensive, but the smart function and low-noise make it worth considering.
Good buyer reviews too!
