Abstract
Methods and systems for monitoring an air filter installed in an HVAC system may include operating the HVAC system in an air filter monitoring mode such as, for example, a fan only mode, and measuring, for example, a differential pressure across the air filter when the HVAC system is operating in the air filter monitoring mode. The method may include evaluating a status of the air filter using, for example, the measured differential pressure value, and in some cases, display the status on a display of an HVAC controller.
