Why is my Daikin Heat Pump not cooling or heating enough?
- SSarah LewisJul 28, 2025
If your Daikin Heat Pump system operates, but the cooling or heating is insufficient, verify that the air inlet or outlet of the heat exchanger unit or indoor unit isn't blocked by obstacles. Remove any obstacles to ensure proper ventilation. Also, check if the air filter is clogged. Verify the temperature and fan speed settings on your user interface. Ensure that doors and windows are closed to prevent drafts. Reduce the number of occupants in the room during cooling operation, minimize heat sources, and block direct sunlight with curtains or blinds. Finally, check that the airflow angle is properly adjusted.
