Your air conditioner keeps you cool during scorching summers and ensures a pleasant indoor environment year-round. However, unusual noises from your AC unit should not be ignored. These sounds often indicate underlying issues that, if left unaddressed, could lead to significant problems and costly repairs. If you encounter these noises, contact a trusted HVAC contractor in Alpharetta, GA, to diagnose and fix the issue.

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



Possible Causes:

Loose or Damaged Components: Parts such as fan blades or motor mounts may become loose, causing unsettling noises.

Compressor Issues: A malfunctioning compressor can produce loud banging noises, requiring prompt attention.

Refrigerant Problems: Low refrigerant levels force the system to work harder, resulting in unusual sounds.

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

The sound of gurgling or bubbling might seem less urgent but shouldn’t be underestimated. It often signals an issue within the unit.

Possible Causes:

Air in the Refrigerant Lines: Air trapped in refrigerant lines can affect the system’s efficiency.

Refrigerant Leak: Leaks can cause gurgling noises and reduce cooling performance.

Blocked Condensate Drain: Clogged drain lines may lead to water backup and gurgling sounds.

AC Humming: The Low-Pitched Noise That Spells Trouble

A low, persistent hum might seem harmless but could be a subtle sign of a problem.

Possible Causes:

Electrical Issues: Faulty capacitors or contactors often produce humming sounds.

Fan Motor Troubles: Issues with the fan motor or its bearings can lead to this noise.

Compressor Strain: A struggling compressor may hum before more significant breakdowns occur.

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

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

Possible Causes:

Belt Issues: Worn or damaged belts can produce high-pitched squeals and need replacement.

Fan Problems: Malfunctioning fan motors or blower wheels may screech during operation.

Lack of Lubrication: Components requiring lubrication may produce screeching noises if neglected.
