Sounds That Signal Your AC Unit Is Failing

In the summer, an AC unit is important for keeping your home or office comfortable. But, if it begins to produce unusual sounds, it’s crucial to pay attention to the issue. Unusual sounds can be an indication that your AC unit is failing or needs maintenance. Here are some of the most common sounds that signal your AC unit is failing:

Banging or Clanking Sounds

Strange noises from your AC unit may indicate that a component is loose or damaged. This could be due to a broken fan blade, a loose component, or a worn-out compressor. It’s essential to turn off the AC unit immediately and contact an HVAC technician to assess the problem.

Whistling or Hissing Sounds

Whistling or hissing sounds coming from your AC unit could indicate a refrigerant leak. Your air conditioning system relies heavily on its refrigerant, but if it begins to leak, it can lead to inefficient or complete failure of the unit. Along with unusual noises, you may also experience a lack of cooling in your home or office. It’s essential to call an HVAC technician to identify and fix the leak as soon as possible.

Grinding or Screeching Sounds

Grinding or screeching sounds coming from your AC unit are never a good sign. These noises could indicate that the AC unit’s motor bearings are failing or that the blower wheel is loose or damaged. These issues can cause significant damage to your AC unit if left untreated, and it’s essential to turn off the unit and contact an HVAC technician immediately.

Clicking Sounds

Clicking sounds are relatively common in AC units, but if the clicking is constant or occurs frequently, it could be an indication of a faulty electrical component. This could be a failing capacitor or a defective thermostat. If you notice a clicking sound coming from your AC unit, it’s best to call an HVAC technician to assess the problem.

Squealing Sounds

Squealing sounds coming from your AC unit can indicate a problem with the belt that drives the blower motor. The belt may be loose or damaged, which can cause it to slip or break. If left untreated, this issue can cause significant damage to your AC unit. It’s essential to turn off the unit and contact an HVAC technician to replace the belt as soon as possible.
