Abstract
Identifying errors with home HVAC systems and notifying the homeowner of the error and potential remedial steps can be useful. In some embodiments, a method is provided including receiving, at an electronic device, a temperature value and an airflow value from sensors located at a vent grate of the HVAC system. A temperature delta value can be calculated using the temperature value and an ambient temperature value. The temperature delta value can be compared with predetermined temperature delta threshold value. The airflow value can be compared with predetermined airflow threshold value. Based on comparing the temperature delta value step and/or the comparing the airflow value step, an error with the HVAC system can be identified. A notification of the error and subsequent potential remedial steps can be sent from the electronic device to the homeowner.
