Abstract: A monitoring system for a heating, ventilation, and air conditioning (HVAC) system of a building is disclosed. The monitoring system includes at least one processor and a computer readable medium that includes instructions executable by the at least one processor. The instructions include: determining a capacity of a filter of the HVAC system based at least on dimensions of the filter; determining a threshold based on the capacity of the filter; monitoring a state of a circulator blower of the HVAC system; and calculating a filter usage based on the state of the circulator blower and one of (i) a power consumed by the circulator blower and (ii) an operation mode of the HVAC system. The instructions also include generating, in response to the filter usage exceeding the threshold, an alert suggesting replacement of the filter.

Abstract: A method of operating a heating, ventilation, or air conditioning (HVAC) monitoring service is described. The method includes: providing a local device for installation in an HVAC system of a residential or commercial building; periodically receiving data from the local device across a wide area network, wherein the received data includes electrical sensor data including at least one of current or power; and storing the received data. The method further includes: analyzing the stored data to selectively identify problems and selectively predict faults of the HVAC system; receiving a subscription fee corresponding to the building, the subscription fee applying to a calendar period; and during the calendar period, providing information on the identified problems and the predicted faults to a customer corresponding to the building.
