How to reduce the noise of a window air conditioner? 

the following are some tips that will help to reduce the noise of the window air conditioner:

  • Secure the unit properly. 
  • Check the casing. 
  • Don’t forget the window frame. 
  • Secure internal components. 
  • Consider lowering the fan speed. 
  • Increase the temperature slightly. 
  • Change the mode setting.

Secure the unit properly:

A window air conditioner can also get loose over time so make sure to check the screws are tight and the seals are in a good position this will help not to make noise.

Check the casting:

If the casing of the air conditioner is loose it will tend to produce noise as it will cause Humming noises for example if the air conditioner air comes in contact with the window frame or any other internal housing it will tend to make noise.

Don’t forget the window frame:

If a window air conditioner is not properly installed it will be noisy. So if a window air conditioner is going to be installed, secure the unit into the window frame so that the vibrating and rattling noises which come from the air conditioner go to the opposite side of the window frame. If a person is able to seal the window frame it will also help to keep the noise of the air conditioner low.
