If you’ve ever been woken up in the night by a loud noise coming from your air conditioner, you’re not alone. Many people find that their air conditioners can be quite noisy, especially when running at full speed. While there’s not much you can do to silence an air conditioner entirely; you can do a few things to reduce its noise. This blog post will discuss the 9 main reasons why air conditioners tend to be noisy and how you can address each one.
Here are common reasons why your aircond is noisy.
1. Banging Air Conditioner Noises
Banging noises emanating from your air conditioning unit may indicate that components have fallen from the compressor’s exterior structure. When central air conditioning units reach their climax of life, it is not uncommon for part of them to fall inside compressors.
This noise occurs when the fan blades hit these components. If you notice this banging noise, you should contact a qualified technician to inspect and repair your unit.
2. Bubbling Sound
Bubbling sounds emanating from your air conditioner may indicate an issue with the unit’s drain line. If the line becomes cracked or blocked, it can cause moisture to build up, leading to a noisy bubbling sound.
While you may be able to clean the unit and clear the drain line yourself, it’s best to consult a qualified technician to ensure the job is done safely and effectively.
3. Humming Sound
Many people associate the sound of humming with relaxation and calm. However, if you’re hearing a humming noise coming from your AC, it could be a sign that the contactor relay switches are damaged.
This part of the AC unit is located in the outside condensing system, which allows the AC to turn on when it receives input from the thermostat. If the contactor relay switches are damaged, they can cause serious problems for your AC unit and may require costly repairs.
So if you notice a humming noise coming from your AC, don’t ignore it – contact a licensed technician right away to have it checked out.
4. Rattling Noise
If you find that your air conditioner is making a rattling noise, there are a few potential causes. First, check to see if any leaves, sticks, or other debris have become lodged in the indoor condenser unit or the air conditioner itself. air filter
If so, simply remove the debris, and the noise should stop. Another potential cause of a rattling noise is loose hardware. Make sure that all screws and bolts are tightened securely. If the noise persists, it may be due to a problem with the electrical contractor. It is best to contact a professional for repair or replacement in this case.
5. Whirring Noise
When the air conditioner starts making a whirring noise, the problem is likely due to an air blower in either the indoor or outdoor unit. The sound of ACs whirring can usually be caused by poor bearings on the blower’s motor and/or malfunctioning fans inside the blower.
When blades fall out, or fans fall apart, the noise may resemble helicopters. Some belts may be damaged. However, problems can sometimes be caused by other components.
6. Clanking Noise or Buzzing Noise
A clanking noise or buzzing sound is one of the most common problems associated with air conditioners, and a variety of issues can cause it. In some cases, the clanking noise may be due to a loose part vibrating against the other components in the unit.
In other cases, it may be due to an imbalanced part such as the compressor or a blade that is out of balance. Regardless of the cause, it’s essential to have the problem diagnosed and repaired as soon as possible to avoid further damage to the unit.
7. Pulsating Noise
A pulsating noise coming from your A/C unit can be alarming, as it may indicate that something is broken. In most cases, the cause is a fan or blade that has come loose. However, if you have recently replaced any panels on your unit, it is also possible that the noise is coming from them.
It is important to have a professional inspect your A/C unit to determine the cause of the noise and make any necessary repairs.
8. Clicking Sound
If your thermostat is making a clicking noise, it could be a sign that it is faulty. Thermostats are responsible for regulating the temperature in your home, and if they are not working properly, it can lead to a number of problems.
One of the most common signs of a faulty thermostat is a clicking noise that occurs during cooling cycles. This noise is caused by the electrical contacts inside the thermostat failing to make a connection.
9. Hissing Noise
The hissing noise coming from your air conditioner could be signalling an air leakage in your home. If you live in an older home, the expansion valves may be defective. Another possibility is that the air filters are not compatible with your system.
In either case, it’s important to get the problem fixed as soon as possible. Otherwise, you’ll continue to hear the noise, and your energy bill will go up as the air conditioner has to work harder to compensate for the leak. In addition, the leak could cause other problems such as water damage if it’s not fixed soon.

Common FAQs
Is it normal for the aircon to be loud?
Some people believe that a noisy air conditioner is simply part of the home cooling process. However, this isn’t necessarily the case. While it’s true that some air conditioners may be louder than others, there are a number of factors that can contribute to excessive noise.
One possibility is that the air conditioner is too large for its cooling space. Another possibility is that the unit isn’t installed properly, which can cause rattling and vibration.
In some cases, a noisy air conditioner may simply need a bit of routine maintenance, such as cleaning the condenser coils or replacing the filter. By troubleshooting the problem, you can often find a solution that will help reduce the noise level.
Is it time to replace a noisy air conditioner?
The air conditioner is one of the most important appliances in the home, providing relief from the heat during the summer months. However, air conditioners can become less effective and noisier as they accumulate dirt and dust over time. If your air conditioner is starting to make a lot of noise, it may be time to replace it.
Not only will a new AC be more effective at cooling your home, but it will also be much quieter. In addition, a new air conditioner will likely come with a warranty, giving you peace of mind in case anything goes wrong. So if your old air conditioner is starting to make a racket, it may be time for an upgrade.
Why does my AC sound like a jet engine?
If your AC sounds like a jet engine, there’s a good chance that something is wrong with the compressor. The compressor is responsible for circulating the refrigerant throughout the system, and it’s located in the outdoor unit.
If the compressor isn’t working properly, it can make a lot of noise. In some cases, the compressor may need to be replaced. However, it’s also possible to clean the compressor and lubricate the moving AC parts.
Conclusion
Noise from air conditioners can be annoying and frustrating. However, there are a few things you can do to try to reduce it. If the noise persists, it is best to contact a professional for repair or replacement. Finally, if you have tried all of these steps and the noise continues, consider purchasing a soundproofing kit to help reduce the sound.
