Changing the filter on your air handler every few months keeps dust from building up on the coils and motor, which can cause the unit to work harder and eventually fail. I also make sure the drain pan and line are clear to prevent water damage. A quick annual check on the blower wheel and belt tension helps maintain good airflow and efficiency.
