Air Conditioner Noises
Most new air conditioners built within the last few years are designed to operate very quietly. When you hear an unusual sounds it's often a sign of inadequate maintenance, or a sign that a part has worn out and is about to fail. By being aware of the different types of AC noises you better determine if there's a problems and have a professional fix the small problems before they lead to an unexpected breakdown.

When an air conditioner is operating normally it will make some familiar sounds. These may include hissing and whirring sounds that are normal and are a result of the unit's blower and compressor operating.

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 conditioner units age, belts often become loose, leading to thumping sounds. A clogged air filter can reduce air flow and can cause the unit to whine loudly as it cycles on and off. Loose hardware on compressor parts can lead to rattling noises.

If you are hearing unusual sounds from you AC or furnace, it's best to have a qualified technician inspect the unit to ensure it's operating safely and reliably.

The Importance of Regular Maintenance

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
