Noisy Window Air Conditioners

1) Use Soundproofing Materials

One of the most effective ways to reduce noise from a window air conditioner is to use soundproofing materials. Materials such as acoustic foam, mass-loaded vinyl, and weatherstripping can be used to create a barrier between the air conditioner and the room.

By reducing the amount of noise that enters the room, you’ll be able to enjoy a more peaceful and relaxing environment. These materials can be easily applied to the air conditioner or the window frame, and they can make a significant difference in noise reduction.

2) Install a Soundproof Box

Another effective way to reduce noise from a window air conditioner is to install a soundproof box. A soundproof box is a wooden or plastic enclosure that fits over the air conditioner and reduces the noise it makes. The box can be lined with soundproofing materials and can also help to protect the air conditioner from the elements. Soundproof boxes can be purchased online or can be made at home with basic tools and materials.

3) Adjust the Fan Speed

Most air conditioners have multiple fan speed settings, and reducing the fan speed can significantly reduce the noise level. While this may slightly reduce the cooling power, it can be a good compromise if you prioritize a quieter environment. Experiment with different fan speed settings to find the one that strikes the perfect balance between noise reduction and cooling power.

4) Clean or Replace Filters

Dirty or clogged air filters can cause the air conditioner to work harder, which can increase noise levels. Regularly cleaning or replacing the filters can not only reduce noise but also improve the efficiency and lifespan of the air conditioner. This is a simple and easy task that should be performed regularly throughout the summer months.

5) Use a White Noise Machine

If all else fails, using a white noise machine can help to mask the sound of the air conditioner and create a more soothing environment. White noise machines emit a steady and calming sound that can effectively mask the noise from your air conditioner.

They can be purchased online or through most home goods retailers and can be a great investment for those who struggle with noise disturbances in general.

6) Use a Foam Padding

Foam padding is an affordable and effective solution to reduce noise from a window air conditioner. This padding is made of open-cell foam and is designed to be placed on the bottom of the air conditioner. The foam padding can help absorb sound and vibrations, reducing the noise level coming from the unit.

7) Use a Rubber Pad

Using a rubber pad can also be effective in reducing the noise from a window air conditioner. This pad is placed on the bottom of the air conditioner and can help to absorb sound and vibrations. Rubber pads are affordable and can be purchased online or at most home goods retailers.

When using a rubber pad or foam padding, it’s important to make sure that it is the correct size and thickness for your specific air conditioner. You can measure the dimensions of your unit and purchase padding that is specifically designed for your model.

8) Install a Sound Barrier

Another way to reduce the noise level of a window air conditioner is to install a sound barrier. A sound barrier is typically made of heavy material such as plywood or drywall and is installed between the air conditioner and the room.

This will block some of the noise from escaping and help create a quieter environment. However, it’s important to note that installing a sound barrier requires some DIY skills and may not be suitable for all situations.

9) Adjust the Thermostat

One reason why a window air conditioner may be making excessive noise is that it’s working too hard to cool the room. By adjusting the thermostat, you can set the temperature to a higher level and reduce the workload on the unit.

This will not only reduce the noise level but also save energy and lower your electricity bill.

10) Check the Fan Blades

Over time, the fan blades on a window air conditioner can become loose or misaligned, causing a loud rattling noise. To fix this, simply turn off the unit and check the fan blades for any damage or signs of wear and tear.

If they’re loose or misaligned, you can try tightening them or adjusting them to their proper position. If the blades are damaged, you may need to replace them altogether.

11) Use a Window Air Conditioner Silencer

A window air conditioner silencer is a device that attaches to the unit and helps to reduce the noise level. It works by absorbing some of the sound waves produced by the air conditioner, thereby creating a quieter environment. These devices can be found online or at some home goods retailers, and they are easy to install.

12) Upgrade to a Newer Model

If your window air conditioner is old and outdated, it may be time to consider upgrading to a newer model. Newer models are typically designed to be more energy-efficient and quieter than older ones.

Additionally, many newer models come with features such as sleep modes and quiet settings that help to reduce noise levels even further. If you are unsure on what model of air conditioner to upgrade to, you can always consult with a professional HVAC technician and find the right one for your home.

13) Install Double-Pane Windows

Another way to reduce the noise level from a window air conditioner is to install double-pane windows. Double-pane windows are designed with two panes of glass with a layer of air or gas in between them. This layer of air or gas helps to block out noise and create a quieter environment.

While installing double-pane windows can be costly, it may be a good long-term investment if you live in a noisy area.

By implementing these additional ways, you can significantly reduce the noise level from your window air conditioner and create a more comfortable and peaceful living space.

14) Clean the Unit’s Coils

Dirty coils can cause an air conditioner to work harder than necessary, which can result in increased noise levels. To clean the coils, turn off the unit and remove the front panel.

Then, use a soft brush or cloth to gently clean the coils. This will help the unit to operate more efficiently and reduce noise levels.

15) Use a Soundproof Curtain

If the noise from your window air conditioner is still bothersome, you can consider using a soundproof curtain. These curtains are designed to absorb sound waves and create a more peaceful environment.

They can be hung on a curtain rod in front of the window and are available in a variety of colors and styles to match your decor.

Bottom Line

In conclusion, noisy window air conditioners can be frustrating and disruptive. However, by using soundproofing materials, installing a soundproof box, adjusting fan speed, cleaning filters, and using a white noise machine, you can effectively reduce the amount of noise your air conditioner makes.

Experiment with different techniques to find the best solution for your specific needs and preferences. A quieter and more comfortable environment is just a few simple hacks away.
