A system and method for evaluating accuracy of operation of sensors of a climate control unit in a premises are disclosed. The method includes receiving, from a plurality of sensors, output signals indicative of a climate within the premises. The method further includes determining one or more climate parameters within the premises based on the received output signals. The method further includes receiving one or more historical climate parameters. The method further includes generating a virtual model configured to generate one or more virtual climate parameters. The method further includes determining, based on comparison of the climate parameters and the virtual climate parameters, a range of variation for the climate parameters. The method further includes determining an accuracy of operation of the plurality of sensors based on comparison of variation between the climate parameters and the virtual climate parameters with the determined range of variation for the climate parameters.
