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

A popping disturbance is a common sign of an insufficient duct design. This occurs when there’s more airflow than your ductwork can manage.

Troubles with your ductwork can lead to other ventilation and air quality troubles, such as:

1. Significant noise
2. Greater energy needs
3. Early system malfunction
4. Irregular heating and cooling
5. Broken AC compressor in the summer
6. Too hot furnace or heat pump in the winter
7. Mold growth inside ducts
