Abstract
Methods and systems are provided for monitoring the condition of an air filter of an HVAC system to provide an indication of when the air filter should be changed. An HVAC controller may be configured to include a filter change notification, wherein the HVAC controller may monitor the current condition of the air filter, and may display a filter change notification on the display when the current condition of the air filter passes a filter change threshold value. In some cases, the HVAC controller may be configured to perform, sometimes at the request of a user, one or more calibration tests on the air filter to help the user identify an appropriate filter change threshold value. Alternatively, or in addition, the HVAC controller may, through a user interface, allow a user to enter and/or change a filter change threshold value, as desired.
