Ductless HVAC systems are famous for their ability to operate whisper-quiet. Any loud sounds from your mini-split in Pinecrest, FL, should grab your attention and make you suspicious that something is wrong. We’ll explain the causes of three especially worrisome ductless HVAC sounds.
Screeching
Broadly speaking, only two things may cause high-pitched screeching or squealing noises to come from your ductless HVAC system. The first is a dangerously high pressure level in your system’s compressor, and the second is either a faulty fan motor or a broken fan belt. In either case, an HVAC service technician will need to inspect your mini-split and fix or replace the offending part.
Rattling
Rattling noises might indicate that some kind of debris, like twigs, pebbles or acorns, has found its way into your system and is bouncing around. Alternatively, it might mean that one of your mini-split’s fan blades has come loose and begun striking another system component.
If you remember to clean your mini-split’s filters every two weeks, you can do away with a significant amount of harmful debris. However, that usually won’t be enough to muffle rattling noises. To do that, you need to schedule professional maintenance.
Hissing
When refrigerant leaks out of your system, you might hear a hissing noise. This sound arises as the coolant flows out of tiny holes in your mini-split’s refrigerant lines. Then, bubbles form as air moves in to displace the refrigerant that has disappeared, causing a gurgling sound.
If you aren’t quite sure whether your system is leaking refrigerant, check for an ether-like odor. Because refrigerant is poisonous, never attempt to handle it on your own. Once you become aware of a leak, evacuate your home and let professionals take care of the situation.
When your mini-split is in trouble, it usually cries out for help. With the guidance above, you now know what to listen for. When you hear something unusual, call RCI Air Conditioning Company and ask for our ductless air conditioning and heating services in Pinecrest, FL.
