Ducted heat pumps making noise in mount uniacke ns is a common concern. While designed for quiet operation, abnormal sounds like grinding, rattling, or banging often signal underlying issues that require attention. If your system, which normally operates around 60 dB(A) (the level of a normal conversation), suddenly gets louder, it's time to investigate.
Quick Noise Diagnosis Guide:
Mount Uniacke's climate presents unique challenges. Cold winters mean more frequent defrost cycles, which can temporarily increase noise. Ice buildup and thermal expansion also affect how your heat pump sounds.
Fortunately, many noise issues are preventable with regular maintenance. Early identification can save you from costly repairs. This guide will help you diagnose common problems and know when to call for professional help.

Heat pumps are never completely silent. Normal operation sounds include a soft whoosh of air, a gentle hum from the compressor, and clicks when the system starts or stops. You might also hear a flowing water sound, which is just refrigerant moving through the lines. These are all part of a hardworking system.
The challenge is when your heat pump develops a new, louder, or more aggressive sound. These changes are red flags indicating worn parts, compressor trouble, or blockages.
