Why do my Samsung Air Conditioner indoor and outdoor units make noises?
- Bbreanna84Sep 9, 2025
Both the indoor and outdoor units of your Samsung Air Conditioner may make noises for a few normal reasons: * A low hissing sound during operation is normal and caused by refrigerant gas flowing through both units. * A low hissing sound when the system starts, stops, or is defrosting is also normal, caused by the refrigerant gas stopping or changing direction. * A squeaking sound can occur due to the normal expansion and contraction of plastic and metal parts caused by temperature changes during operation.
