Temperatures have only recently begun to cool down in our area. This means that up until last week, you were probably using your air conditioner on a regular basis. In doing so, you might have noticed that it was beginning to make some concerning noises that you didn’t hear from it at the beginning of the cooling season.
Now, you may be tempted to wait until next spring to get the noises checked out, but this can be a mistake, particularly if you are planning on using a furnace this winter—as the problem may be with your HVAC systems’ shared ductwork. But even if faulty or breached air ducts aren’t to blame, there’s no reason to ignore potential repair needs. Keep reading to learn what noises you should keep an ear out for.
Chances are, if you hear your AC humming, it’s not a very merry tune. An electronic humming is often the sign of a failed capacitor, which causes its intended motor to struggle when turned on or running. This motor could burn out, resulting in expensive repairs.
This is another ominous sound—it probably resembles steam escaping a pipe. The most likely cause of this is a refrigerant leak. A loss of refrigerant will lead to a loss of cooling power, and probably an overheated compressor.
Grinding or Screeching
An over-stressed motor that is close to burning out might make this sound. The motor may have become overly dirty or lost lubrication, which causes this unpleasant mechanical noise. A dying compressor is another possible culprit.
This is very likely the sign of a loose mechanical part somewhere inside your AC system’s cabinet. This can result from bent fan blades striking the outside fan casing, or in older air conditioners it can be that a snapped fan belt is hitting other components. Either way, the noise and the sounds mentioned above are worth having a professional investigate.
