Why do my heating vents pop?
Popping and banging sounds are caused by the movement of duct walls due to pressure changes. Hot air makes your ductwork expand; cold air makes it contract. How much popping noise you hear depends on 1 or more of these 4 factors: The shape of your ducts.Click to see full answer. Also asked, how do…

CHECK DAMPERS AND ACTUATOR Dampers can either be open or closed. Check the dampers on the supply side of your ductwork and try opening them up one at a time to see if this reduces the popping and banging noises. You can also adjust the actuator inside of the duct dampers up or down to reduce the duct noises.One may also ask, how do I quiet noisy ducts? High static pressure makes airflow more audible Adjust the fan speed. Your blower or furnace fan should be set to deliver the proper airflow per ton. Add ductwork. Add a bypass duct. Add or expand grilles and registers. Replace existing registers and grilles with high velocity models. Besides, why does my heating ductwork make banging noises? Causes of Banging or Popping in Ductwork When the heating or cooling system comes on, there’s an expected buildup in pressure within the ducts. The expanding pressure can cause the long sides of the rectangle to expand as the air is flowing. This can cause an initial popping or banging noise.What is a duct silencer? Air Duct Silencers: Commercial – Industrial – HVAC Duct Silencer. Silencers or Air Duct Silencers are an engineered product specifically designed to control airborne noise in ducts, openings in buildings, enclosures, or from equipment. They may also be referred to as industrial sound attenuators.
