A soft sound of the AC fan while switching on is common. Likewise, a small clicking sound while switching it off is not something to worry about. But if the AC is producing a screeching noise, hissing sound, bubbling sound, rattling noise, or a disturbing clicking sound repeatedly, it is high time you repair your AC. Here are some probable causes and their solutions for a noisy AC.

Is Your AC Making A Cracking Or Popping Noise?

A continuous cracking or popping sound might be because water has gone inside any sensitive part of your AC which is usually protected from water. Ice may also form inside the unit in extremely low-temperature settings, especially when the draining is not proper. In this case, you should first switch off the AC and check if there is any water or ice logged. This problem mostly occurs after heavy rainfall.

Is Your AC Making A Banging Noise?

If your AC is making a banging noise, it might be due to some loose or broken part inside the AC compressor. The connecting rod, piston pin, crankshaft, or the wobble plate might be the connecting rod. The problem may also be in the indoor blower. If it is a continuous and loud banging noise, you might need to replace your compressor to fix this.

Is Your AC Making A Screeching Noise?

Nothing is more irritating than an air conditioner making a screeching or squealing noise. This kind of weird sound is produced in an AC due to a faulty fan motor bearing. If the fan motor bearing is damaged, you have to replace it. There is no other way out. A broken fan belt can also be the reason for the squealing sound. Such sounds can also signal that high pressure is generated inside the compressor unit.
