Why is my Daikin FCAG35BVEB Air Conditioner not cooling or heating enough?
- W
  Willie RossAug 11, 2025
  To address insufficient cooling or heating with your Daikin Air Conditioner, first, ensure that neither the indoor nor outdoor unit's air inlets or outlets are obstructed. Remove any obstructions to allow free airflow. Next, verify that the air filter is clean. Also, check your temperature and fan speed settings on the user interface. Make sure that all doors and windows are closed to prevent drafts. Consider if there are too many people in the room or excessive heat sources. Block direct sunlight with curtains or blinds, and confirm that the airflow angle is correctly adjusted.

  If your Daikin Air Conditioner system isn't operating at all, begin by checking for a power outage and wait for the power to be restored. Note that the system should restart automatically after power returns. Then, check for any blown fuses or tripped breakers. Replace the fuse or reset the breaker if needed.
