It’s the middle of the night. You’re desperate to fall asleep, but one thing is stopping you: the loud whirring and humming of your air conditioner.
Noisy AC units are not a new problem, but they can certainly be a frustrating one. Keeping your home air-conditioned is a priority, but it can be not so pleasant if the tradeoff is a noisy air conditioner unit.
Luckily, there are a few things you can do to reduce the noise of your AC unit. In this guide, we’ll share some of the best tips for blocking air conditioner noise, including:
- Installing a sound blanket
- Installing a fence
- Soundproofing your house
- Placing your unit in the optimal spot in your home
- Investing in a newer air conditioner model
Reasons for Noisy Air Conditioners
Before discussing how to reduce AC noise, it is first essential to understand why air conditioners are noisy in the first place. After all, if you don’t know the problem, you can’t fix it. Here are some of the most common reasons that could make your air conditioner noisier:
- Age: Older air conditioners are louder than newer ones because experts keep inventing new soundproofing technology. Even if they’re otherwise functioning correctly, some older air conditioners will be noisy because experts hadn’t invented better technology when it was made.
- Loose parts: An air conditioner has a lot of parts, and if one comes loose, it can put extra stress on the other parts. A loose part will eventually cause your air conditioner to make more noise. Your solution could be repairing the loose part.
- Worn-out compressor: If your compressor is worn out, it could be making your unit a lot noisier than it has to be. Checking to see if your compressor needs replaced could be the solution to your problem.
- Cleanliness: When an air conditioner is dirty, it makes more noise. AC units continually gather dust and other debris, so cleaning out your fans could improve the noise problem.
In general, if your air conditioner is being abnormally loud, it’s probably a good idea to get it checked out for repairs. However, sometimes air conditioners are just naturally noisy. If that’s the case, how can you block the noise?
Tips to Reduce Air Conditioner Noise
There are two stages in air conditioner noise reduction: before and after installation. If you have control over both stages, you’ll be able to reduce a lot of the noise. Even if you can only control one stage, you can still do a lot to block the noise.
If you haven’t installed your AC unit yet, or if you are planning to install a new one, there are several measures you can take before installation to reduce future problems with noise:
- Keep away from bedrooms and living rooms: You know which parts of the house you use frequently, so if you can choose, you should install the AC unit as far from these rooms as possible. You should especially install the air conditioner far away from bedrooms.
- Don’t place in a narrow hall: If you install your AC unit in a narrow hallway or a similar tight space, the sound will bounce off the walls and become amplified. Brick walls and reflective surfaces are especially conducive to allowing sound waves to echo.
- Place away from doors or windows: Sound can easily slip into your home through doors or windows, so installing your air conditioner away from these areas will help reduce noise. Besides, if you open your window, you don’t want to be met with the sound of a noisy machine.
- Purchase a newer model: Sometimes, the best way to cut down on sound is to buy a more contemporary or higher quality air conditioner model. It might be more expensive, but that money will go toward a quieter machine.
How to Reduce Air Conditioner Noise
If your AC unit is still noisy after you install it or had no choice in where you install it and don’t want to replace it, there are still several options available to help with AC noise reduction.
Install a Sound Blanket
One of the easiest and most cost-effective solutions for reducing noise is to install a sound blanket to act as an air conditioner noise barrier. You can check with your AC unit’s manufacturer for a blanket size that will fit your unit, or you can purchase a universal sound blanket. It only takes a few minutes to install, but you’ll be able to notice the noise reduction immediately.
A sound blanket can aid the overall functioning of your air conditioner. The blanket will help with air circulation, keeping the air conditioner from overheating.
Install a Fence
If your AC unit is outdoors, you can install a fence to act as an air conditioner sound barrier. This will prevent as much sound from traveling outside the fence, creating a barrier. This installation will also help significantly reduce the noisiness of your unit. If you choose to go this route, make sure to select materials that are good for dampening sound. Typically, wood or vinyl are both excellent choices.
Make sure you leave about 3 feet between the air conditioner and the fence as you install your fence. This spacing will allow adequate airflow to prevent the unit from overheating. You will also want to ensure there are no gaps between the fence boards, which will allow more sound to seep through.
Soundproof Your House
If your air conditioner is still too loud, there is one more place you can turn. Rather than figuring out how to quiet a noisy air conditioner, you can instead focus on your house. Soundproofing your house won’t make the air conditioner itself quieter, but it will make it more peaceful for everyone inside the house. As long as the noise from the AC unit isn’t bothering your neighbors, this could be the solution for you!
