Have gathered all information needed to provide estimate for the scope of work to correct airflow issues. Reduced airflow to 1st and 2nd floors by switching pin from 30% down to 20% for the first floor and trimmed the second floor from 50% to 30%. When both zones are open blower is now running at 83% capacity to lower static pressures.
