What to do if my Daikin FDXM35F3V1B9 Air Conditioner is not cooling or heating enough?
- DDestiny CurtisAug 9, 2025
If your Daikin Air Conditioner isn't cooling or heating sufficiently, consider these potential causes and solutions: * Ensure that neither the air inlet nor outlet of the outdoor or indoor unit is blocked by obstacles. Remove any obstructions to allow free airflow. * See if the air filter is clogged. Contact your dealer to clean the air filter. * Verify the temperature setting, air flow angle and fan speed setting. Refer to the user interface manual to adjust them. * Make sure that doors and windows are closed to prevent wind from entering and direct sunlight is blocked with curtains or blinds. * If cooling, consider whether there's an excessive heat source in the room or too many occupants.
