  If your Daikin Air Conditioner system isn't cooling or heating sufficiently, several factors could be at play. Check for obstructions blocking the air inlet or outlet of either the indoor or outdoor unit and ensure they are well-ventilated. A clogged air filter can also be the culprit, in which case you should ask a qualified service person to clean the air filters. Other potential causes include improper temperature settings, low fan speed, incorrect airflow angle, open doors or windows, direct sunlight entering the room, too many people in the room, or excessive heat sources. Addressing these issues can help restore optimal cooling or heating performance.
