A monitoring system for a heating, ventilation, and air conditioning (HVAC) system of a building includes a monitoring device installed at the building, a monitoring server located remotely from the building, and a review server. The monitoring device measures an aggregate current supplied to components of the HVAC system and transmits current data based on the measured aggregate current. The monitoring server receives the transmitted current data and, based on the received current data, assesses whether failures have occurred in first and second components of the HVAC components. The monitoring server generates a first advisory in response to determining that the failure has occurred in the first component. The review server provides the first advisory to a technician for review and, in response to the technician verifying that the failure has occurred, transmits a first alert.
1. A monitoring system for a heating, ventilation, and air conditioning (HVAC) system of a building, the monitoring system comprising: a monitoring device installed at the building, wherein the monitoring device is configured to (i) measure an aggregate current supplied to a plurality of components

The monitoring system of claim 4 wherein the review server is programmed to: in response to an efficiency decrease associated with the failure being greater than a predetermined threshold, transmit the first alert to both the contactor and the customer, andin response to the efficiency decrease associated with the failure being less than the predetermined threshold, transmit the first alert to only the contractor. 7. The monitoring system of claim 1 wherein: a second advisory is generated in response to the monitoring server determining that the failure has occurred in the second component,the review server provides the second advisory to one of a plurality of technicians for review,the plurality of technicians includes the technician, andthe review server, in response to the technician verifying that the failure has occurred in the second component, transmits a second alert. 8. The monitoring system of claim 1 wherein the monitoring device samples the aggregate current over a time period, performs a frequency domain analysis on the sampled aggregate current over the time period, and transmits current data including a current value and frequency domain data to the monitoring server. 9. The monitoring system of claim 8 wherein the monitoring server identifies transition points in the current data and analyzes the frequency domain data around the identified transition points. 10. The monitoring system of claim 8 wherein the monitoring server determines whether the failure has occurred in the first component by comparing the frequency domain data to baseline data. 11. The monitoring system of claim 1 wherein the monitoring device records control signals from a thermostat and transmits information based on the control signals to the monitoring server. 12. The monitoring system of claim 1 further comprising a second monitoring device located in close proximity to a second enclosure of the HVAC system, wherein the second enclosure includes at least one of a compressor and a heat pump heat exchanger,wherein the second monitoring device (i) measures an aggregate current supplied to a plurality of components of the second enclosure and (ii) transmits second current data based on the measured aggregate current supplied to the plurality of components of the second enclosure to the monitoring device, andwherein the monitoring device transmits the second current data to the monitoring server. 13.
