The present disclosure relates to the monitoring of a cooling device. More specifically, the methods and apparatus for measuring efficiency of a cooling unit. Monitoring may be done through measurement of the electrical use of the cooling unit and additional environmental variables. This measurement may create a profile for the cooling unit that may be compared to historical performance of the unit itself, the expected performance of the same model or similar model, as well as a combination of both. These measurements may be used to create predictive analysis for expected future performance. These measurements may be used for comparison to the performance of a malfunctioning unit. These measurements may be used to determine when the unit is performing outside the expected range and therefore malfunctioning.
