Why is my Carrier 42QHC012D8S not cool/warm enough?

If your Carrier Air Conditioner is not cooling or warming enough, ensure the temperature and mode settings are correct. Check if the air filters are clean and that all windows and doors are closed. Also, make sure that the airflow is unrestricted in and out of both the indoor and outdoor units, and that the fan speed is set to high with louvers allowing maximum flow.
