Diagnosing 3 Troublesome Ductless Noises in Appling, GA

Ductless mini-splits are typically known to operate with less noise than traditional central HVAC systems. Any loud or unusual sounds should immediately alert residents of Appling, GA, who own these systems. Let’s review three troublesome noises you may one day notice coming from your ductless mini-split system.

Rattling

Loose mini-split components can cause quite a racket. Unsecured nuts and bolts can create a loud rattling. You may also hear this noise if your system’s parts have significant amounts of debris in them.

Typically, the solution to this problem is to ask a trained HVAC service technician to come to your home and perform some maintenance on your system, during which they will clean any debris and tighten loose parts. In some cases, age and cumulative wear and tear may cause these problems. Service technicians can suggest part replacement or repairs at that point.

Hissing

This sound is the hallmark of a refrigerant leak. Refrigerant is essential to heat transfer, so your system won’t be able to perform effectively without it. The hissing sound occurs as gaseous refrigerant escapes through holes in your system’s refrigerant lines.

These holes may be tiny and could be anywhere. Moreover, refrigerant is a highly toxic substance that can cause severe neurological damage if you inhale it. For these reasons, you should leave your home and call an HVAC service technician immediately if you hear hissing noises from your ductless mini-split system.

Buzzing

Debris causing blockages and loose parts may force your mini-split to start buzzing. Broken fan blades or motors are also possible culprits. Most seriously, there might be extensive underlying electrical issues with your ductless HVAC system.
