Why is my air conditioning unit making noise?

If your air conditioner is making weird noises while turned on, there’s a chance that there may be something wrong with your air conditioning unit. Don’t put off getting it checked out – if the noises persist for too long, you could run into more expensive and damaging issues. Here are some common noises you may hear and how to correct them:

  • Gurgling: Gurgling usually means there’s a problem with your refrigerant line. A professional can help you locate and fix this problem if you cannot find it on your own.
  • Crackling: Crackling can come from two different things: debris in your air conditioning unit or aging ductwork. Debris in your outdoor unit will make noises outside your house, while the mature ductwork will create noises inside your house.
  • Hissing: Hissing can originate from a faulty refrigerant line, internal valve leak, or the compressor.
  • Buzzing: Buzzing usually indicates there’s a electrical issue.
  • Clicking: Clicking can mean the fan inside your air conditioning unit is misaligned or another part of the air conditioning unit has become loose.
  • Pulsating: Pulsating can come from a loose part.
  • Loud Noise: A noticeably loud noise from your air conditioning unit can indicate an issue with the compressor, damper, fan, or air handler.
  • Humming: Humming can be linked with fan motor issues or a damaged rely switch.

If you are experiencing any one of these noises or problems, it’s recommended to shut down your system and call a professional. A licensed technician at Blanton & Sons will be able to inform you if it’s safe to run your air conditioning.
