Ductless HVAC systems ordinarily run with minimal noise. The sudden emergence of any bizarre or jarring sounds should cause concern. Here’s some information that homeowners in Brunswick, GA should know about three troublesome noises that their ductless systems might make.
1. Squealing or Screaming
Sharp-pitched squealing or screaming typically occurs when your system has a faulty fan belt. Malfunctioning fan motors and blower wheels may also have a similar effect. In such a situation, HVAC technicians will need to replace these parts for you.
2. Whistling or Hissing
These are the noises that your mini split is most likely to make when it’s experiencing a refrigerant leak. Refrigerant gas will make a hissing sound as it escapes from holes in the system’s refrigerant lines. Sometimes, though, friction may create a high-pitched whistle.
Refrigerant is extremely dangerous, and you must never try to stop it from leaking or replace it on your own. Those are jobs only a team of trained HVAC technicians can perform.
3. Rattling or Banging
If any of your ductless system’s parts come loose for any reason, you may start to hear rattling noises. As the system does its work and energy courses through it, the parts will shake around. In some cases when a part comes loose, you may hear sharp bangs coming from the system.
The parts that are most likely to come loose include things like bolts, crankshafts and fan blades. It’s also possible that debris is tumbling around in your system. HVAC technicians can investigate all these possibilities and set things right when they perform biannual maintenance.
Once you know what to listen for, your ears can be excellent tools with which you might save your mini split from trouble. When you hear something weird, call The A/C Guys and schedule ductless AC services near Brunswick, GA.
