Problem
Possible causes
The indoor unit makes
noises
A squeaking sound is heard when the system is off or in cool mode.
The noise is also heard when the drain pump (optional) is in operation.
A squeaking sound may occur after running the unit in heat mode due
to expansion and contraction of the unit’s plastic parts.
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 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.
