How to pick the quietest window air conditioner

Decibels (dB) measure sound intensity. The higher the decibel level, the louder the noise. You can check a window AC’s dB level on its box or online listing.

However, the model with the lowest dB level may not be the quietest window air conditioner. An inefficient or improperly sized model will make more noise.

When selecting the quietest window air conditioner, consider the following factors.

Size

Air conditioners too small for the room they’re cooling tend to be noisy. The fan and compressor overwork themselves to supply the right amount of cool air. This generates a constant loud noise because the unit can never keep up.

To avoid overworking your AC, use the chart below to determine the correct capacity for your room’s size.

Room size (square feet)AC capacity (BTU)
2006,000
3009,000
40012,000
50015,000
60018,000

Energy efficiency

Combined Energy Efficiency Ratio (CEER) signifies the energy efficiency of a window air conditioner.

The rating represents the unit’s energy usage in two scenarios:

  • When it’s cooling your room
  • When it’s not running but is still plugged into a power source

Usually, the quietest window air conditioners have a CEER rating of 10 or higher.

Fan setting

ACs tend to run quieter on lower fan settings. Their blades don’t move as quickly, so they generate less noise.

Setting your fan to low when it’s comfortable to do so can mitigate noise. Avoid using turbo mode if you’re concerned about noise levels.

What makes an air conditioner noisy?

The quality of the inner parts plays a key role in an air conditioner’s noise levels. Window ACs made with inexpensive parts are more likely to rattle.

Still, quality isn’t everything. A perfectly well-made AC can still be loud if it’s the wrong size for the room it cools.

Following are some factors that make a window air conditioner noisy. The window ACs on our list are built to combat many of the issues below.

Compressor

The compressor turns refrigerant from gas to liquid form. Compressors come in single, dual, and variable-speed varieties. Single and dual-speed compressors turn on and off frequently and work at higher speeds, generating more noise.

Airflow

Big air conditioners are naturally louder. The bigger the air conditioner, the more air it pushes out. With high airflow comes loud noise levels.

For example, the 15,000-BTU units on our list are louder than the 8,000-BTU units. This is because the 15,000-BTU unit has to generate more airflow to properly cool the room.

Vibrations

Window air conditioners sometimes bang against the windowsill, creating loud vibrating noises. This happens due to improper installation or sizing.

Before purchasing a window AC, make sure it’s the right size for your window. Measure your window and check the recommended window dimensions before purchasing a window AC.
