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.
