Abstract: Systems and methods are provided for evaluating performance of a heat exchanger, such as a condenser, using rules-based logic. A plurality of sensors can measure various operating properties of the heat exchanger and transmit corresponding measurement information to a controller. The controller can (i) evaluate the measurement information for a plurality of rules in which each rule considers an operating parameter of the heat exchanger that is based on the measurement information to provide a set of operating values; compare the set of operating values to a rules matrix in which each of a plurality of possible diagnoses for the heat exchanger are associated with a corresponding set of predetermined values from a set of the plurality of rules; and (iii) based on the comparison, determine at least one likely diagnosis for the heat exchanger from among the plurality of possible diagnoses.

Abstract: A residential energy efficiency rating system that may incorporate one or more sensors situated at one or more residential properties, an aggregation and sending device connected to the one or more sensors, a central data receiver and processor connected to the aggregation and sending device, a historical device data storage connected to the central data receiver and processor, and a residential energy efficiency rating calculator connected to the historical device data storage.

Abstract: A freeze prediction system for components such as one or more water pipes situated in a building. The building may have a heating system, a mechanism with a temperature setting connected to the heating system, and an indoor temperature indicator connected to the thermostat. A call may be made for heat if thermostat setting is greater than an indoor temperature. A check may be made as to whether a call for heat may be answered. Outdoor conditions may be read and accounted for in the system. An expected time may be calculated of a freeze danger. One may determine whether the freeze danger is significant according to the expected time of freeze danger compared to a predetermined time. If the freeze danger is not significant, a regular equipment failed alert may be sent out. If the freeze danger is significant, a pipe freeze warning alert may be sent out.
