Abstract
Methods and systems for monitoring the condition of a new air filter installed in an HVAC system are disclosed. In one example, an input that indicates a new air filter has been installed may be accepted, and in response, the HVAC system may be automatically operated in an air filter verifying mode, in which the fan of the HVAC system is activated to drive air through the new air filter. While in the air filter verifying mode, a measure related to an amount of flow restriction presented by the new air filter may be received. A status of the new air filter may be determined based, at least in part, on the received measure related to the amount of flow restriction presented by the air filter of the HVAC system. Once the status of the new air filter is determined, an indication may be displayed on a display, which may communicate the determined status of the new air filter to a user.
