Air conditioner noise reduction is a simple and yet effective DIY project.
Air conditioners have been known to cause disruptive noise. But cooling your home shouldn’t involve causing more discomfort.
Noisy outside air conditioners can also annoy your neighbors as well as disrupting their quiet stay at home.
Read my detailed guide on the quietest through wall air conditioners.
Luckily there are different ways you can make any AC unit quiet. In this article, we are going to discuss:
- RV air conditioner noise reduction
- Outdoor air conditioner noise reduction
According to studies published on Purdue website, sound levels between 115-140 decibels are considered pain threshold for humans.
While most laws dictate that the HVAC system should have noise ratings 70 and 75- this level of noise can still cause disturbances.
So how do you make your HVAC system quieter?
Let’s find out:
RV Air Conditioner Noise Reduction
One of the primary reasons why you go on vacation is to get away from your noisy city.
All you wish for is the peace and calmness of nature far from the city.
Unfortunately, a noisy RV air conditioner can make it impossible to enjoy your vacation. Below are quick fixes on how you can fix a RV air conditioner making pulsating noise or other noises.
RV Air Conditioner Silencer
The best product for this purpose is Dometic RV AC silencer that takes less than 15 minutes to install.
If installed correctly, this AC silencer can reduce noise levels by 8-10 decibels.
A recycled cotton lining is installed inside the duct system to ensure that noise gets stopped before it gets inside your car.
After installing the silencer, you should be able to enjoy some little peace and calmness once again.
Outdoor Air Conditioner Noise Reduction
Outdoor ACs will not only cause unwanted noises for you, but they can also be a nuisance to your neighbors as well. Below are different ways to quiet an outside AC unit
Use Soundproofing Blanket
Soundproofing blanket is one of the most affordable soundproofing materials on the market today.
The rule of soundproofing is adding more mass as possible, and the more the mass, the more soundproofing.
The same applies when it comes to soundproofing an outside air conditioner unit.
Adding several layers of the sound-absorbing blanket will help reduce noise to manageable levels.
These blankets are specially designed for soundproofing and can reduce up to 40% noise.
Brinmar’s sound blanket wrap will sound dampen the air conditioner compressor. It can fit different models and sizes.
It has loop closures and hooks to facilitate installation. It’s designed in such a way that it will allow sufficient air circulation for maximum air supply.
The sound blanket is designed with the concept in mind that air conditioners are continually running, and they are prone to overheating.
Select Location Carefully
It’s essential to choose the location of your heat pumps and air conditioners carefully before installing a new air conditioner.
Install your AC unit away from bedrooms and other rooms with frequent activity to help minimize noise disruption.
Additionally, when consulting with your contractor, it’s important to avoid installing the air conditioner where the ducts in your house are in narrow corridors.
The sound from your AC will reverberate off the walls, and the narrow corridors will amplify sound.
In addition also avoid installing your AC in corners where multiple surfaces can deflect the sound.
Another effective method of dealing with a noisy air conditioner is building a fence.
The concept behind this hack is making the fence as high as possible to cover your entire AC unit from all sides.
You can use bamboo wood or any other material at your disposal. For best results, build a four-sided fence to ensure that all the four sides block unwanted noise.
You can also add some bushes and shrubs around the air conditioner; this way, you will also achieve similar results.
Noise barriers are also used in reducing traffic noise, and so can you implement the same hack to minimize air conditioning noise.
You can plant vegetation to help absorb sound and also act as a buffer that will limit and block sound waves that travel between your AC and your home. Ideally, all noise barriers should be taller than the air conditioner.
Create the best surface for your AC unit
Poorly installed AC unit can have unsteady contact with the ground /floor, and as a result, it can cause vibrations that can be transferred through walls.
Attaching your AC unit sturdier on the walls or ground will help deal with vibrations hence reducing impact sound.
Regular AC Maintenance
You will be surprised to know most HVAC system noise could be a result of damage, clogs or worn-out components.
You can prevent all these problems by performing regular air conditioner maintenance.
The maintenance should be included changing the filters, clearing seasonal debris, clearing drains, and updating your AC unit whenever possible.
Are there Quiet Air Conditioners
If your old AC is making unbearable noises, it’s time to replace it.
The best alternative would invest in a quiet air conditioner or RV air conditioner. These units have been designed with noise reduction in mind.
Some of these old models are way cheaper and outdated and fixing them might cost you more than investing in a new model
They are designed to ensure that they emit noises in the lowest decibels possible. One of the most recommended silent RV ACS are the Dometic rooftop and Coleman air conditioner.
On Air Conditioner Noise Reduction
Air conditioners are handy tools that keep us cool during the hot days and nights of summer.
Unfortunately, some models can be noisy and interfere with the quiet and calm living you’ve always wished for.
Fortunately, there are different ways you can quiet a noisy HVAC unit.
Most of the recommended hacks above are simple and can be implemented in minutes.
Building a fence is the only technical hack that will require technical skills. However, this hack is also the most rewarding as it reduces 98% noise.
Therefore, if you want a hack that will help you deal with all the unwanted noises, try building a fence for your AC.
