  Your Carrier Air Conditioner might not be providing sufficient cooling due to several reasons. Check if airflow is obstructed and remove any obstacles. Ensure the air filters are clean, as dirty filters restrict air circulation. Also, make sure doors and windows are closed. Verify that the fan speed isn't set to low; if it is, increase it to high. Adjust the airflow direction according to the selected mode. Finally, ensure the selected temperature is not higher than the room temperature in cooling mode and correct it if necessary.
