You may be panicking if you hear a squealing, hissing, humming, rattling, buzzing, thumping, or screaming noise coming from your AC unit. Air conditioners make noise because it is a kind of machine with a lot of parts that operate to keep your home at a comfortable temperature. Old air conditioners are noisier than the modern ones. Nowadays, technologies and other equipment that we may use for our daily needs and comfortability are evolving. Newly designed air conditioners are not that noisy compared to the old units. So, if you hear something strange that you think could symbolize an issue with your AC, it’s a good idea to turn off your central air conditioner unit as a precaution until it can be examined. Air conditioning units may cost too much of your money for the repair and replacement. It’s never convenient for us to experience a broken air conditioner. A yearly inspection and tune-up can prevent some future problems.
Here some common sounds that your AC produces and what it may signify:
- Squealing- a slipped belt produces squealing noise. The belt connects the compressor to the engine. Old and misaligned belts may squeal right before it bites the dust.
- Hissing or Whistling- a whistling noise is often the sound of a duct leak. If your ducts are leaking, you may be losing precious cool air and energy, which may increase your electric bill.
- Humming- a humming noise can mean your capacitor is starting to fail. It could simply mean that your fan motor needs a technician for the repair. If you hear a humming sound coming from your system, call a trusted HVAC professional to correctly diagnose the issue.
- Rattling- if something is making a rattling noise, the cause is most likely loose parts or screws. The louder the rattling noise, the more out of place the part is, so if you hear loud rattling – don’t take it for granted!
- Buzzing- is a noise that may indicate loose connections on the compressor, but it also occurs when the voltage running through your AC unit is at the incorrect amperage. Buzzing might also show that your blower is going bad or out of balance.
- Thumping- a thumping noise can occur in your outside unit when your yard waste becomes caught in the fan. If you hear clunking or banging, calling an HVAC professional is the best thing to do, but before contacting them you should check your outdoor unit first.
- Screaming- a high-pitched screaming noise occurs when your compressor has failed, and it needs you to replace it. It may consume much of your money to replace the entire unit. Also, this sound may be a sign of high internal pressure within your compressor.
