HVAC systems should not make loud and disturbing noises. Ductless mini-splits, which can operate extremely quietly, certainly should not do so. We’ll discuss a few worrisome ductless mini-split noises that homeowners in West Harrison, IN should know about.
Squealing or Screeching
This piercing noise typically indicates that your system has a faulty fan belt. If the system’s blower motor has malfunctioned and its parts have started scraping against one another, that may also cause this sound. You’ll need to fix or replace either the belt or the motor.
Rattling
Rattling noises may suggest that some parts have come loose inside your system. These could be fasteners, fan blades or something else. Also, there might be little twigs, pebbles, acorns or other bits of debris inside your system that have begun rattling around.
In either case, the way to silence this noise is to ask for maintenance services. HVAC technicians can secure all loose parts and remove all meddlesome debris from your mini-split.
Hissing or Gurgling
These noises are the telltale indicators of a refrigerant leak. If rust, abrasion or blunt force damage creates holes in your ductless mini-split’s refrigerant lines, and refrigerant gas starts to escape through those holes, you’ll hear hissing noises. Then, when air begins displacing the refrigerant, it may form bubbles and produce gurgling noises.
Since refrigerant is toxic and harmful, never attempt to do anything about these leaks on your own. Instead, if you hear these sounds or detect a whiff of ether in the air, leave your home. Then, request professional help to deal with the problem.
Keep your ears open for any strange noises coming from your mini-split. Your reaction to such noises can significantly impact your comfort levels in West Harrison, IN. If you hear anything that sounds odd, call Western Hills Heating and Air Conditioning, and ask for our ductless HVAC services.
