When your ductless AC system in Davidsonville, MD, is running normally, it’s quiet and efficient. If you hear loud noises coming from your indoor or outdoor equipment, this alerts you that something isn’t working optimally and needs attention. Let’s explore some of those unusual sounds and what they might mean when your ductless AC system runs loud.
Rattling
Your AC condenser sits outdoors, exposed to the elements and debris, such as leaves, pebbles and twigs that can accumulate inside it. This debris can cause a rattling noise. It’s a good idea to have your ductless AC system cleaned and serviced seasonally by our service technicians to keep rattling to a minimum.
Buzzing or Humming
If you hear buzzing or humming coming from your condenser, this is likely the result of electrical issues. If the outdoor unit is drawing more power than usual, it may make such noises. These noises might also indicate a broken fan blade or motor.
Hissing or Whistling
A constant hissing or whistling sound is a sign that your ductless AC system is leaking refrigerant. The pressure of the escaping refrigerant will produce such noises. An issue like this requires swift attention so it doesn’t cause further damage to the system.
Grinding
If you hear grinding, there’s likely friction between moving parts inside the equipment that requires tightening or lubrication. This noise commonly originates from loose motor bearings, the fan motor or the blower wheel. Grinding noises can occur at the outdoor condenser or the individual indoor units.
The noises you hear coming from your ductless AC system in Davidsonville, MD, are signs that the equipment needs service from one of our skilled service technicians.
