Why is my portable AC not cooling enough?

The most common cause of a portable AC not cooling a room is lack of adequate airflow. If the air filter is dirty or clogged, there may not be enough air flowing over the evaporator coils and the coils can become too cold and frost over. This restricts airflow and a portable AC won’t cool the room.
