Air Conditioner Making Noises? Here are the Possible Causes

Most new air conditioners built within the last 5 years are designed to operate very quietly. When you hear unusual noises, it is usually the result of a lack of maintenance or a sign that a part has worn out and is about to fail. By being aware of these noises you can address the small problems before they leads to a breakdown.

When your air conditioner is working normally it will often make some noises. Subtle thumping and whining sounds are normal. By becoming familiar with the normal operating sounds that an air conditioner makes, you will be able to more easily recognize unusual sounds that could be cause for concern.

The Sounds of a Malfunctioning Air Conditioner

Air conditioners have many parts; there are fans, hoses, belts, compressor motors, coils and other components that work together to move cool air throughout your home. As air conditioners age belt often become loose, leading to thumping sounds. A clogged air filter reduces air flow and can cause the unit to whine as it cycles on or off. Loose hardware on compressor parts can lead to rattling sounds.

Preventative maintenance is the best way to minimize the likelihood of air conditioner repairs. An AC tune-up includes the following steps that keep your air conditioner operating quietly and reliably:

  • Inspection and lubrication of all moving parts
  • Inspection and replacement of worn belts and hoses
  • Replacement of dirty air filters
  • Ensuring that the unit cycles on and off properly
  • Inspection of electrical connections
  • Inspection of refrigerant levels
