As you get used to the ductless cooling system in your Semmes, AL home, you likely become attuned to the noises the system makes. Your ductless AC should be quiet during operation, though some minor noises are common. However, take a look at the list below of some noises that may indicate troubles with the system so that you know when to call our service techs for repairs.
Rattling or Banging
Loud rattling or banging noises inside your ductless cooling system may indicate damaged or loose parts. These parts make a loud banging as they get moved around and hit other parts of the system. Loose parts may not bang against other pieces of the ductless system, but they may rattle or vibrate when the system operates.
Hissing
Hissing sounds inside your ductless mini-split often indicate air bubbles in the refrigerant line. This happens when the line becomes damaged and allows air inside, letting refrigerant leak out. Refrigerant leaks are hazardous to the environment and prevent your system from conditioning air properly, so this problem requires immediate professional repair services.
Grinding
Loud grinding noises that sound like metal rubbing against metal may mean that your bearings have become damaged or are not properly lubricated. Bearings require lubrication to prevent wear and tear during operation. Dry or damaged bearings should be repaired immediately to prevent further damage that could put your ductless cooling system out of commission.
When you know the difference between normal operational sounds and noises that could signify a problem, you’re better able to care for your ductless system. If you need ductless AC repairs due to strange or alarming noises, call our trusted service techs at Air Specialty so that we can help minimize damage and restore comfort to your Semmes, AL home.
