Your aircon is supposed to keep you cool and comfortable. But sometimes, it starts making strange sounds. These noises can be annoying and may mean something is wrong. So, why is your aircon noisy? Let’s find out the common causes and what you can do to fix them.
1. Loose or Dirty Fan Blades
First of all, your aircon may be noisy because the fan blades are loose or dirty. When this happens, you might hear rattling sounds, especially when you turn the unit on or off.
✅ What to do: Book a general service or chemical wash to clean and tighten the fan blades.
2. Clogged Air Filters
Next, a blocked air filter can stop air from flowing properly. This can make the aircon work harder and cause whistling or humming noises.
✅ What to do: Clean or change your filters every month or two.
3. Worn-Out Motor or Bearings
Sometimes, the motor or bearings inside the unit wear out. This can cause buzzing or grinding noises.
✅ What to do: Call a professional to check and replace any broken parts.
4. Refrigerant Leaks
Another cause could be a refrigerant leak. If you hear a hissing or bubbling sound, this might be the issue. Leaks are not only noisy but also dangerous.
✅ What to do: Contact a technician right away. This problem needs fast attention.
5. Loose Parts or Panels
Over time, parts inside your aircon can come loose. When the unit runs, these parts may rattle or vibrate.
✅ What to do: A technician can tighten any loose parts during a service visit.
6. Normal Expansion Sounds
Lastly, some clicking or popping sounds are normal. They happen when metal parts inside the aircon expand or shrink with changes in temperature.
✅ What to do: If the noise is quick and not too loud, you don’t need to worry.
In short, a noisy aircon might mean it needs a quick clean — or it could be a bigger problem. Don’t ignore the sounds. Instead, let the team at Lion City Air Conditioner Services take a look. With the right care, your aircon can run quietly and smoothly again.
