Abstract:
A method includes initiating, by a controller of a heating, ventilation, and air conditioning (“HVAC”) system, a filter calibration procedure, curve fitting a first line based on a plurality of static pressure measurements and corresponding flowrates of air, and generating a second line based on the first line. The method further includes determining a first static pressure measurement sensed by at least one sensor in response to determining that a first flowrate of air has been moved by the at least one blower and comparing the first static pressure value to a predicted static pressure value of the second line, the predicted static pressure value corresponding to the first flowrate of air. The method further includes determining that an air filter of the HVAC system has no more usable life in response to determining that the first static pressure value is greater than the predicted static pressure value.

Claim (Index 20):
The at least one controller of  claim 18 , wherein the filter calibration procedure comprises:\n in response to determining that a second flowrate of air has been moved by the at least one blower, determine a second static pressure value of the HVAC system; in response to determining that a third flowrate of air has been moved by the at least one blower, determine a third static pressure value of the HVAC system; and in response to determining that a fourth flowrate of air has been moved by the at least one blower, determine a fourth static pressure value of the HVAC system.
