The Best Tips and Tricks To Keep Your Window Air Conditioner Quieter

How to quiet a noisy air conditioner

Keeping your window air conditioner quiet is not as difficult as you might think. With a little effort, you can easily make your unit run more quietly. Here are some of the best tips and tricks for doing just that:

  • Ensure Proper Installation
  • Check for leaves, twigs, or other debris
  • Tighten any loose bolts, screws, belts, or spring clamps
  • Ensure the fan blades are properly aligned 
  • Lubricate moving parts
  • Invest in good quality window air conditioner

You may also want to install an insulation blanket over your window air conditioner. This can help reduce the noise as well.

1. Ensure Proper Installation

If you are looking for a great way to make your air conditioning unit quieter, you must get it installed properly in the first place.

If there is too much space between the sides of the unit and your window, it will allow more noise to escape.

You can ensure that this doesn’t happen by installing weather stripping around the sides of your air conditioner before installing it in the wall or window.

Weatherstripping is a rubber material that helps fill in any gaps between objects, so they are completely sealed off from each other.

2. Check for leaves, twigs, or other debris

One of the easiest things you can do is make sure that there are no leaves or twigs in your window air conditioner.

This will help keep it quiet by reducing the friction between moving parts inside the unit and preventing them from rubbing together.

If you can’t clean it out yourself, you can always call a professional to get the job done.

3. Tighten any loose bolts, screws, belts, or spring clamps

Belts and screws can become loose over time, which will cause the unit to be louder as it runs. You can fix this by tightening any loose bolts, screws, or spring clamps.

4. Ensure the fan blades are properly aligned

If the fan blades on your air conditioner are not properly aligned, they can cause noise and vibration. You can ensure that they are correctly aligned by using a level to check their position.

If they need to be adjusted, you can do so by loosening the screws that hold them in place and then turning them clockwise or counterclockwise until they are properly aligned.

5. Lubricate moving parts

Moving parts inside your air conditioner can cause noise if they aren’t lubricated regularly.

To avoid this problem, use oil on any moving part that needs it every few months (or as needed). This will help them move more smoothly and quietly.

Machine oil or white grease are both good choices for this purpose.

6. Invest in good quality window air conditioner

Sometimes, the squeaky noise from your window air conditioner could be an alarm that it’s time to replace the unit.

If you have had your air conditioner for more than six years, it might be time to invest in a new one.

Quality comes at a price, but it may be worth the investment in this case. A high-quality air conditioner will run more quietly and efficiently than a lower-quality model.


How do I know if my window air conditioner is too loud?

Noise levels above 70 decibels are considered to be too loud. If you can hear your air conditioner when talking on the phone or having a conversation, it is noisy.

Can I install my window air conditioner in any kind of window?

You can’t use a regular window for an air conditioner. The unit has to be attached to a sliding window.

If your house doesn’t have that type of vent, you may need to install one or find another way to cool your home during the summer.

Can I use a window air conditioner to replace my central AC unit?

Window air conditioners are not meant to replace central AC units completely.

They are smaller and more limited in their abilities, so they are best used as supplemental cooling devices in homes with a central AC system installed.

How do I properly clean my window air conditioner?

You can clean your window air conditioner by vacuuming the inside of the unit and wiping it down with a damp cloth.

Make sure to remove any leaves, twigs, or other debris that may have gotten inside. Check the filters and replace them if they are dirty. 

How often should I service my window air conditioner?

Depending on the type of air conditioner you have, it might need to be serviced once a year or as needed.

If you’re not sure how often your unit needs maintenance, consult the owner’s manual for more information about its specific requirements.
