True or False? An unbalanced duct will cause noise and vibration.

An unbalanced duct system can indeed lead to both noise and vibration. This occurs because when the airflow through the ducts is unequal, certain areas may experience higher pressure, causing reactive forces that result in vibration. Additionally, the uneven distribution of air can create turbulence, which amplifies sound levels within the ductwork.

Properly balanced ducts ensure that air flows evenly throughout the system, which minimizes these issues. When a system is unbalanced, it can lead to inefficient operation of the heating and cooling equipment, increase energy consumption, and create uncomfortable conditions due to inconsistent temperatures in different areas of a building. Balancing the ducts helps to maintain comfort, efficiency, and system longevity while reducing noise and vibration.
