Not only that, but strange noises coming from your air conditioner can also indicate that something is wrong with the unit. In this article, we will discuss how to troubleshoot an air conditioner that is making strange noises.
Understanding the different types of noises
Before you begin troubleshooting your air conditioner, it is essential to understand the different types of noises it can make. Here are some common types of noises that air conditioners can make:
Rattling or vibrating sound:
If your air conditioner is making a rattling or vibrating sound, it could indicate that there is something loose inside the unit.
Hissing or whistling sound:
A hissing or whistling sound coming from your air conditioner could indicate a refrigerant leak.
Buzzing or humming sound:
A buzzing or humming sound can be caused by a malfunctioning motor or a loose component in the unit.
Squealing sound:
A squealing sound coming from your air conditioner can indicate that the belt inside the unit is slipping or that the bearings need to be lubricated.
Now that you know the different types of noises that air conditioners can make, let’s look at some troubleshooting steps you can take.
Step 1: Turn off the air conditioner
The first thing you should do when you hear strange noises coming from your air conditioner is to turn it off. This will prevent any further damage to the unit and will also ensure your safety. After you turn off the air conditioner, wait for a few minutes before proceeding to the next step.
Step 2: Check the air filter
A clogged air filter can cause your air conditioner to make strange noises. It can also reduce the efficiency of the unit and increase your energy bills. To check the air filter, remove it from the unit and hold it up to a light source. If you can’t see the light shining through the filter, it means it is clogged and needs to be replaced.
Step 3: Inspect the outdoor unit
The outdoor unit of your air conditioner can also be the cause of strange noises. Inspect the unit and look for any signs of damage, such as dents or bent fins. If you find any damage, it could be affecting the performance of the unit, causing it to make strange noises. You may need to call a professional to repair or replace the damaged part.
Step 4: Check the fan blades
The fan blades inside your air conditioner can become loose over time, causing them to make strange noises. To check the fan blades, turn off the air conditioner and inspect them for any signs of damage or looseness. If you find any issues, you may need to tighten or replace the fan blades.
Step 5: Listen for refrigerant leaks
As mentioned earlier, a hissing or whistling sound can indicate a refrigerant leak. To listen for a refrigerant leak, turn on the air conditioner and listen carefully for any hissing or whistling sounds. If you hear any, it is best to call a professional to repair the leak.
Step 6: Call a professional
If you have tried all the troubleshooting steps and your air conditioner is still making strange noises, it is best to call a professional. A qualified technician will be able to diagnose the issue and repair your air conditioner.

To troubleshoot the issue, turn off the air conditioner, check the air filter, inspect the outdoor unit, check the fan blades, listen for refrigerant leaks, and if necessary, call a professional. By following these steps, you can help prevent further damage to your air conditioner and ensure that it is functioning properly.
However, it is important to note that regular maintenance of your air conditioner can help prevent strange noises from occurring in the first place.
