Possible Causes
A rushing air sound may occur when the louver resets its position.
A squeaking sound may occur after running the unit in HEAT mode due to expansion and
contraction of the unit's plastic parts.
Low hissing sound during operation: This is normal and is caused by refrigerant gas flowing
through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is defrosting: This noise
is normal and is caused by the refrigerant gas stopping or changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts caused by
temperature changes during operation can cause squeaking noises.
The unit will make different sounds based on its current operating mode.
The unit may accumulate dust during extended periods of non-use, which will be emitted when
the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity.
The unit may absorb odors from the environment (such as furniture, cooking, cigarettes, etc.)
which will be emitted during operations.
The unit's filters have become moldy and should be cleaned.
During operation, the fan speed is controlled to optimize product operation.
Interference from cell phone towers and remote boosters may cause the unit to malfunction.
In this case, try the following:
• Disconnect the power, then reconnect.
• Press ON/OFF button on remote control to restart operation.
