Zusammenfassung:A system and method are described for self-diagnosing heating, ventilation and air conditioning (HVAC) systems. The system and method correlate an HVAC control mode of a particular HVAC unit with an energy usage for the particular HVAC unit in order to match normal patterns in energy usage with the HVAC control mode. This correlation allows the system and method to identify potential problems with the particular HVAC unit based on deviations from normal patterns.
