Reasons Why Air Conditioners Are Noisy

It’s important to understand why air conditioners make noise before trying to fix it. That way, you’ll better understand what you need to do. Here are some of the reasons why your air conditioner makes noise:

  • Age: Older AC models are much noisier than new ones. That’s because manufacturers are finding new ways to make them quieter by using soundproofing materials. Even if you have an older AC model that still works, it might be better to get a new one. 
  • Loose parts: As the AC unit is made of many smaller components, if some of them is loose, it can create more noise than usual. If this is the case, then you must repair that loosened part.
  • Worn-out compressor: The worn-out compressor is another reason why the AC unit is noisier than usual. Check if the AC compressor needs to be repaired or replaced.
  • Regular Maintenance: Dirty air conditioners make much more noise than usual. Therefore, regular maintenance of air conditioners is very important for them to work properly, which also affects the noise.

Tip! If your air conditioner is making too much noise, it’s a good idea to call a professional to check it.

But sometimes, air conditioners are just normally loud. In that case, what can you do to block the noise? Here are some tips that you can use to reduce or block AC noise.

There are two parts to making an air conditioner quieter: before you install it and after you install it. If you can control both parts, you can make it a lot quieter. If you can only control one part, you can still reduce a lot of noise from your AC unit.

Here we will introduce some tips you can do if you haven’t already installed an air conditioner unit in your home. Be sure to follow these steps:

  1. Install AC Away From Bedroom & Living Room: If possible, install your AC unit far away from the bedroom or living room. That way, you’ll significantly reduce the noise in your house while the air conditioner is turned on.
  2. Avoid Narrow Hall: Placing an air conditioner in a narrow hall will increase the noise because the sound will bounce off the walls, which you definitely want to avoid. Therefore, try to avoid narrow halls.
  3. Avoid Installation Near Doors & Windows: Installing an AC unit near the window or door can also increase the noise in your room. Therefore, keep your AC unit away from doors and windows to reduce air conditioner noise.
  4. Buy A New AC Unit: If you have an older air conditioner model that is very loud, you don’t have many options to turn it down. What you can do is to buy a new model, which is also eco-friendly and thus you will save energy.
