How to Solve the Problem of a Noisy Air Conditioner

A noisy air conditioner can be a nuisance that leaves you scratching your head in search of a solution. For example, you might be experiencing a sound that has you wondering, “Why does my AC unit make a buzzing noise?” No matter what, dealing with the noise can be aggravating.

Insider Tip

You can purchase a quiet air conditioner model if you’re concerned about noise levels.

Fortunately, you have a few options to help minimize its impact. Of course, these solutions will only dampen the noise, so if your unit is running louder than usual, it’s important to determine why you’re experiencing excessive noise in the first place. In this case, checking into basic troubleshooting, like how to find a leak in a central air conditioner, might be helpful.

Use Air Conditioner Sound Blankets

If you want to go all out, you can have an air conditioner sound blanket, also known as a compressor blanket, installed around your AC compressor. This is a great way to muffle compressor noise, a huge source of unwanted sound from your AC.

Provide Regular Maintenance

The biggest benefit of regular maintenance is avoiding problems that can lead to airflow issues, which can be a source of excess noise from your AC.

There are multiple benefits to understanding your AC unit and how to take care of it properly. Basic preventative maintenance might include knowing how to remove mold from air conditioner coils. Along the way, you’ll likely learn fun new tricks, like how to make a window AC colder.

Warning

Excessive noise can signify that your air conditioner compressor is on the fritz.

Avoid Narrow Hallways

This is a strange one, but it makes sense. Narrow hallways tend to amplify the noise of your air conditioner because they are usually devoid of furniture and other objects that would otherwise dampen the sound. It is recommended that you do not install your AC in any space that is hollow enough to amplify noises. It’s also better for air circulation.
