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

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

Problems with your ductwork may lead to other ventilation and air quality issues, including:

  1. Too much noise
  2. Greater energy consumption
  3. Early system failure
  4. Uneven heating and cooling
  5. Nonfunctioning AC compressor in the summer
  6. Overheated furnace or heat pump in the winter
  7. Mold growth inside ducts

Reach a qualified company in Hillsborough, like Fras-Air/General Service Experts, to check your residence’s ventilation system. We can make advice for duct repair or installation.
