Noisy air conditioners are one of the people’s most common complaints about their AC systems in Penang. There are several reasons why your air conditioner might be making noise, from loose screws to a clogged filter. At PG1 Aircond, we compile a list of the 10 most common reasons why your aircon might be too loud.
Loose screws or other loose parts
One of the most common causes of an air conditioner being too loud is that there are loose screws or other parts in the unit. If you can hear rattling, buzzing, and other kinds of sounds coming from inside your air conditioner, then take a closer look at its inner workings to see if any parts are loose. You may need to tighten some screws or replace a part that has come loose.
Another common cause of noisy air conditioners is condensation that has built up in the unit. If water starts leaking from your unit, it could be because condensation has accumulated over time and created blockages in certain areas. To fix this, you’ll need to have a professional clean out your air conditioner and remove all the accumulated water.
A clogged filter can also lead to your air conditioner being too loud. If your unit’s filter is dirty, it will restrict airflow and cause the unit to work harder than it needs to. This can lead to noise as well as decreased efficiency. To fix this, simply clean or replace your air conditioner’s filter according to the manufacturer’s instructions.
Another reason why your air conditioner might be noisy is that the bearings in its motor are worn out. When these bearings start to fail, they can create a grinding noise that will be loud and hard to ignore. Unfortunately, there is no quick fix for worn-out bearings, so the best thing you can do is have them replaced as soon as possible to restore your unit’s quiet operation.
If your air conditioner has several different kinds of parts from other manufacturers, it could be causing strange sounds that make it loud. This isn’t a common problem, but if this is causing the noise in your aircon, you’ll need to have all the mismatched parts replaced with ones from the same manufacturer to keep things running smoothly again.
Another reason your air conditioner might be noisy is that it vibrates too much. This can happen if the unit is not properly secured to your wall or ceiling, so be sure to check this and make sure that it’s all fastened tightly. You might also have a problem with the compressor, fan, or other parts of the unit that are making it vibrate too much and causing noise in the process.
If your air conditioner has loose ducts, this can lead to rattling as well as decreased efficiency. If you’ve noticed these issues in your aircon recently, then take a closer look at its ducts to see if any of them are loose or disconnected from their connections in some way. Tightening any loose connections should help stop the noise and improve efficiency.
A final common cause of noisy air conditioners is leaking refrigerant. This can lead to hissing or bubbling noises coming from your unit and decreased efficiency. If you think your air conditioner might be leaking refrigerant, then you’ll need to have it checked out and repaired by a professional as soon as possible.
Debris in the fan
Another potential cause of noisy air conditioners is debris caught in the fan blades. If you can see leaves, dirt, or other objects in the fan, this could be causing the noise. Simply turn off your air conditioner and clean out the fan to remove the debris and quiet things down.
Finally, one last potential cause of noisy air conditioners is simply old age. If your unit is more than 10 years old, then it’s likely that some of its parts have started to wear out and aren’t working as well as they used to. In this case, you’ll need to either have them repaired or replaced to get your air conditioner running quietly again.

What Is A Normal Aircon Noise
Not all aircon noises should be a cause for concern, though. If you’re wondering, “What is a normal aircon noise?” then here are some things to consider.
First, it’s essential to know that there is such a thing as an “air conditioner startup sound.” This is because when you first turn on your unit, it has to go through booting up and making all the necessary connections. This can sometimes cause a slight humming noise that should only last for a few seconds.
Another common air conditioner noise that isn’t causing concern is a gentle whooshing sound. This is usually just the sound of air moving through the vents and shouldn’t be too loud or obnoxious.
In general, any noise that your air conditioner makes that is louder than a low hum or subtle whooshing sound may be a sign of a problem. If you can’t figure out what’s causing the noise, or if it continues for long periods or gets louder over time, it’s best to get in touch with an AC professional to assess the situation and recommend solutions.
However, suppose your aircon makes unusual noises regularly but isn’t causing issues like decreased efficiency or frequent breakdowns. In that case, there probably isn’t anything to worry about, and you are perfectly safe to leave things as-is. In these cases, simply keeping an eye on how often the unit makes strange sounds can help give you peace of mind that everything is working correctly.
If your air conditioner has been making strange noises lately, don’t ignore it! Take a closer look at what might be causing the noise and take action to fix the problem so that you can enjoy a quiet operation once again.
