Why is my Daikin FXZA15A2VEB not cooling or heating enough?
- N
  Nathaniel LozanoAug 9, 2025
  Several factors can cause insufficient cooling or heating in your Daikin Air Conditioner. Make sure that air inlet or outlet of outdoor or indoor unit is not blocked by obstacles and remove them to ensure free airflow. Check the air filter and clean it if clogged. Verify the temperature and fan speed settings on your user interface. Close any open doors or windows. Reduce the number of occupants or heat sources in the room. Block direct sunlight using curtains or blinds. Ensure the air flow angle is properly adjusted.
