  There could be several reasons why your Daikin Air Conditioner isn't cooling or heating sufficiently. Make sure that the air inlet or outlet of the outdoor or indoor unit isn't blocked by any obstacles. Check the remote controller display, and clean the air filter if it indicates it's time. Verify the temperature and fan speed settings on your remote controller. Ensure doors and windows are closed, and consider if there are too many people in the room or excessive heat sources. Also, check if direct sunlight is entering the room and adjust the airflow angle.
