  If your Carrier Air Conditioner isn't cooling the room enough, consider these factors: * Ensure that the airflow isn't obstructed. * Clean the air filters, as dirty filters reduce air circulation. * Close any open doors and windows. * Increase the fan speed from “Low” to a higher setting. * Adjust the set temperature to be cooler if it's too high in cool mode. * Use curtains or shades to block strong sunlight. * Finally, verify that the unit is appropriately sized for the room.
