Issue
Possible Causes
Both the indoor unit and outdoor unit make noises
A low hissing sound may occur during operation. This is
normal and is caused by refrigerant gas flowing through
both the indoor and outdoor units.
A low hissing sound may be heard 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.
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 operations.
The 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.
