Issue

Possible Causes

The indoor unit 

makes noises

A rushing air sound may occur when the louver resets its 

position.

Due to expansion and contraction of the unit's plastic parts, a 

squeaking sound may occur after the unit is run in HEAT mode.

Both the indoor
and outdoor
units make
noises

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 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 outdoor unit 

makes noises

The unit will make different sounds based on its current 

operating mode.

Dust is emitted 

from either the 

indoor or outdoor 

unit

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 emits a 

bad odor

The unit may absorb odors from the environment (such as 

furniture, cooking, cigarettes, etc.) which will be emitted 

during operation.

The unit’s filters have become moldy and should be cleaned.

The fan of the 

outdoor unit does 

not operate

During operation, the fan speed is controlled to optimize 

product operation.

Operation is 
erratic or
unpredictable
or the unit is
unresponsive

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 the ON/OFF button on the remote control to restart 

operation.

NOTE:

 If the problem persists, contact a local dealer or your nearest customer service 

center. Provide them with a detailed description of the unit malfunction, as 

well as your model number.
