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

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

Issues with your ductwork might create other ventilation and air quality troubles, like:

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

Call an experienced company in Birmingham, like Norrell Service Experts, to look at your house’s ventilation system. We can offer suggestions for duct repair or installation.
