clean the filter(s) more frequently. Once every 2 weeks is
recommended.

Ensure the drain piping from the indoor unit is free of blockage.
During cooling operation, water should drip from the outlet of the indoor
unit's drain piping. If there is no evidence of water from the drain outlet
after several hours of cooling it may be that the drain is blocked or the
relative humidity is low. If you think the drain is blocked stop the air
"

contact your installer. This code will indicate to the installer / repairer
what the problem may be.
