These AC Noises Mean Trouble

Your air conditioner keeps you cool during scorching summers and ensures a pleasant indoor environment year-round. However, there are times when your AC unit may start making unusual noises, and these sounds should not be ignored. They are often indicators of underlying issues that, if left unaddressed, could lead to more significant problems and costly repairs. Get in touch with an HVAC Contractor in Alpharetta, GA to help diagnose and fix these noises.

Banging and Clanking: What's Hiding Behind These AC Noises?

Possible Causes:

  • Loose or Damaged Components: Parts within the AC unit, such as fan blades or motor mounts, can become loose and lead to unsettling noises.

  • Compressor Issues: A malfunctioning compressor can cause loud banging noises and should be addressed promptly.

  • Refrigerant Problems: Low refrigerant levels can result in the system working harder and generating unusual sounds.

Gurgling AC: What Does That Sound Indicate About Your System?

The sound of gurgling or bubbling from your AC system might seem less urgent, but it’s not to be underestimated. This noise could signal a problem within your unit.

Possible Causes:

  • Air in The Refrigerant Lines: Gurgling often occurs when air is trapped in the refrigerant lines, affecting the system’s efficiency.

  • Refrigerant Leak: A leak can lead to gurgling noises and a decrease in cooling efficiency.

  • Blocked Condensate Drain: A clogged drain line can cause water to back up and create gurgling sounds.

AC Humming: The Low-Pitched Noise That Spells Trouble

A low, persistent hum from your AC unit may seem harmless, but it can be a subtle sign of a problem.

Possible Causes:

  • Electrical Issues: A humming noise can indicate problems such as a faulty capacitor or contactor.

  • Fan motor Troubles: Issues with the fan motor or its bearings can result in a humming sound.

  • Compressor Strain: When the compressor struggles to start, it may produce a humming noise, which can precede a more significant breakdown.

Screeching AC Unit: A Squeal of Distress You Can't Ignore

A screeching or squealing sound is one of the most distressing noises your AC can make, indicating a pressing issue.

Possible Causes:

  • Belt Issues: A worn or damaged belt can produce a high-pitched screech and should be replaced promptly.

  • Fan Problems: A malfunctioning fan motor or blower wheel can create screeching noises.

  • Lack of Lubrication: Components that require lubrication, if not properly maintained, can lead to screeching.
