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

A popping noise is typical sign of an undersized duct design. This takes place when there’s higher airflow than your ductwork can control.

Troubles with your ductwork might cause other ventilation and air quality problems, such as:

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