The expanding pressure can cause the long sides of the rectangle to expand as the air is flowing. This can cause an initial popping or banging noise.How do you fix noisy ducts? High static pressure makes airflow more audible Adjust the fan speed. Your blower or furnace fan should be set to deliver the proper airflow per ton. Add ductwork. Add a bypass duct. Add or expand grilles and registers. Replace existing registers and grilles with high velocity models.
