No matter what type of air conditioner you have in your Gluckstadt, MS, home, it’ll produce some sounds. However, if you’ve recently had a ductless AC installed, you may not yet have sufficient experience to identify abnormal noises. Here are three ductless AC noises that mean trouble for your system:
Rattling or Crackling
Most modern ductless AC air handlers run so quietly that it’s difficult to tell they’re operating. So, if one of yours starts making a rattling or crackling sound, it means there’s a problem. Either of these sounds calls for a visit from one of our professional HVAC service technicians.
Typically, rattling indicates that some component in the air handler needs tightening. It can happen due to vibrations produced by the air handler’s blower motor.
Crackling, on the other hand, can indicate ice forming on your air handler’s evaporator coil. That can result from a dirty air filter or a refrigerant leak somewhere in your mini-split.
Buzzing Ductless AC Noises
If your ductless AC system makes buzzing noises, it typically means there is an electrical problem. If the sound originates from an air handler, it may indicate a loose connection or a faulty wire. Alternatively, it could mean the mini-split’s blower fan needs replacement.
When you hear buzzing from your ductless AC’s outdoor unit, it could also be the result of a loose electrical connection. However, it may also mean that your system has a failing capacitor. In that case, a simple capacitor replacement should stop the noise.
Hissing Ductless AC Sounds
All air conditioners rely on pressurized refrigerant lines to function. If you ever hear your ductless AC system emitting a hissing sound, turn it off immediately. Hissing typically indicates that your ductless AC’s refrigerant system has a leak on its high-pressure side, which requires immediate repair.
If your ductless AC system starts making any unusual noises in Gluckstadt, MS, don’t ignore them. Contact Modern Air to schedule an AC repair appointment as soon as possible.
