Halloween is here, and if you notice some creepy noises, don’t be afraid: they may be coming from your Air Conditioning unit. Read on to discover what are the most common spooky AC noises, what are their causes, and how to fix them.
If you hear a rattling sound, that’s not a ghost shaking its chains, but your AC unit asking you to pay attention. This type of noise usually occurs when some component of your unit dislodges, be it a single screw or an entire part of the system. These are some of the most likely culprits of rattling noises:
- Loose panels/screws
- Misaligned fan blade
- Broken motor
A squealing or screeching noise is spooky, but it’s also a typical indicator of a bad fan belt in the blower. It may also be caused by a lack of oil in some of the moving parts of your unit. A squealing noise during the starting phase is normal in some models. But if the sound persists, it’s best to call an HVAC professional to check it out.
Whenever you hear a high-pitched whistling or screaming noise coming from your unit, turn it off immediately and call an expert. The most likely cause for this type of noise is a refrigerant leak, which may endanger to your family. Another possible cause is high pressure within your compressor, a problem that also requires expert help.
