Abstract: A method of operating a heating, ventilation, or air conditioning (HVAC) monitoring system includes, at a remote monitoring apparatus, receiving and storing frames of data from a local monitoring device installed at a building. Each of the frames includes time domain current data based on a measured aggregate current supplied to a plurality of components of an HVAC system of the building and frequency domain data based on the measured aggregate current. The method includes, based on the frequency domain current data and exclusive of individual current data from a plurality of individual current sensors, determining an individual contribution of a first component of the HVAC system to the measured aggregate current. The method includes transmitting information based on the stored current data to an HVAC manufacturer. The method includes, if a problem is identified with the first component using the determined individual contribution, transmitting an alert message.

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.

Abstract: A system and method include a monitoring system that monitors operating parameters of an HVAC system at a customer location and that generates an alert or service request based on the operating parameters. A server is in communication with the monitoring system and receives the alert or service request from the monitoring system, compares the alert or service request to a listing of alerts and service requests covered under a service plan associated with the HVAC system at the customer location, determines whether the alert or service request is covered under the service plan based on the comparison, and schedules and dispatches a contractor to perform service under the service plan when the alert or service request is covered under the service plan.

Abstract: A system and method includes a database storing faults, each fault having an indicator corresponding to whether the associated fault is designated for self-maintenance. A monitoring system is in communication with the database and monitors operating parameters of an HVAC system at a customer location, detects or predicts a fault in the HVAC system, determines whether the fault is designated for self-maintenance, and communicates an alert corresponding to the fault to a customer device. When the alert received by the customer device indicates that the fault in the HVAC system is designated for self-maintenance, the customer device displays an identification of a replacement component associated with maintenance for the fault and a first interface to receive at least one of a first selection for a contractor to deliver the replacement component and a second selection for purchasing the replacement component through a commercial retailer.

Abstract: A system and method for a contractor locator and dispatch service is provided. A customer device is associated with an HVAC system at a customer location. Contractor devices are each associated with a contractor at a contractor location and stores contractor information including contractor location data corresponding to the contractor location and contractor availability data corresponding to an availability of the associated contractor. A server receives a service request for the HVAC system from the customer device and contractor information from each of the contractor devices. The server applies selection criteria to the received contractor information and determines potential contractors for the service request based on the selection criteria.
