A system, method, and computer program product include a temperature determination control unit in communication with a monitored temperature sensor within an environment and one or more checking temperature sensors within the environment. The temperature determination control unit is configured to receive a monitored air temperature from the monitored temperature sensor. The temperature determination control unit is configured to receive a checking air temperature from the one or more checking temperature sensors. The temperature determination control unit is configured to compare the monitored air temperature with the checking air temperature. The temperature determination control unit is configured to determine an accuracy of the monitored air temperature based on a comparison of the monitored air temperature with the checking air temperature.
