Why is my Carrier 42QFA009DS Air Conditioner not cooling or heating properly?
- MmarshallseanAug 12, 2025
If your Carrier Air Conditioner isn't cooling or heating well, make sure the temperature and mode are set correctly. Check if the air filters are clean and that all windows and doors are closed. Ensure that nothing is blocking the airflow in or out of the indoor and outdoor units. Also, verify that the fan speed is set to high and the louvers are allowing maximum airflow.
