Your frozen AC unit may not be cooling the room properly because the ice buildup on the coils restricts airflow and reduces the unit's ability to cool effectively. This can be caused by issues such as dirty air filters, low refrigerant levels, or a malfunctioning thermostat. It is important to address the underlying cause of the freezing to restore proper cooling function.
