If the problem continues after the filter change, the issue may involve the blower motor or limit switch.

Yes, and it is the most common cause of faults that look like equipment failure. A restricted filter makes a furnace overheat and shut down on its limit switch, freezes an air conditioning evaporator coil solid, and makes the blower motor draw high current until it fails early. Two things matter more than brand: the filter must fit its slot tightly, because a loose filter lets air bypass it completely, and a very high MERV rating in a system not designed for it restricts airflow enough to cause the same overheating it was meant to prevent. A filter that darkens within weeks in Ohio City, OH usually means duct leakage is pulling in unfiltered air.
