4 Ductless HVAC Noises You Never Want to Hear in Burleson, TX

October 23, 2024

Ductless HVAC systems in Burleson, TX typically don’t make much noise during operation. If your ductless HVAC system makes any of the following noises, you’ll need to take action to resolve the situation and keep things working smoothly.

1. Hissing

Your ductless system uses refrigerant to transfer heat from the outside to the inside and vice versa. If your system develops a leak, refrigerant will escape, resulting in a hissing noise and problems with cooling and heating. Since refrigerant can be hazardous to your health and the environment, a qualified technician should handle this issue.

2. Rattling

Sometimes, vibrations from your ductless mini-split can cause a rattling noise, either from improper installation or loose internal components. Improper installation can potentially lead to problems with your wall or the system itself, and loose components can hit and damage other parts. In either case, have a technician assess and remedy the situation to prevent additional issues.

3. Grinding

Bearings play an important role in a ductless HVAC system, reducing friction and boosting longevity. Over time, those bearings can wear out, leading to increased friction and a grinding or squealing noise. A technician can replace the bearings to allow for smoother movement and reduce the chances of further damage.

4. Buzzing

Buzzing may mean there is a serious issue with the electrical components in your ductless mini split. Loose connections or frayed wires can cause the system to draw more power, which can potentially overload your circuit breaker. To prevent any complications and decrease the chances of an electrical fire or damage, hire a professional to inspect your system and perform any necessary repairs.

The above four unusual sounds could mean that something is wrong with your ductless HVAC system. If left unchecked, these problems could become more concerning and costly to fix. For help with any ductless HVAC repair, contact our team at NexGen Heating & Air Conditioning.
