ISSUE POSSIBLE CAUSES
Both the indoor unit
and outdoor unit 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 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 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.
Operation is erratic,
unpredictable, or 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 ON/OFF button on the thermostat to restart operation.
NOTE
If 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.
