What's causing my duct work to pop when the furnace starts or stops?

A popping disturbance is a common sign of an undersized duct design. This happens when there’s higher airflow than your ductwork can control.

Issues with your ductwork may cause other ventilation and air quality troubles, like:

  1. Excessive noise
  2. Greater energy use
  3. Premature system failure
  4. Unbalanced heating and cooling
  5. Damaged AC compressor in the summer
  6. Too hot furnace or heat pump in the winter
  7. Mold increase in ducts
