Systems and methods for checking proper airflow within a container (307) having a refrigeration unit (320) are provided. The system includes one or more sensors (358) located within the container configured to measure at least one airflow characteristic, and a controller (360) in communication with the one or more sensors. The controller is configured to store predetermined information related to airflow within the container, wherein the predetermined information includes minimum airflow criteria related to the at least one airflow characteristic, receive data from the one or more sensors, compare the received data with the predetermined information, and provide an indicator when the comparison indicates that the received data does not meet or exceed the minimum airflow criteria.
