What could be a consequence of not monitoring static pressure in a duct system?

• A. Unbalanced airflow and excessive wear on fans.
• B. Reduced energy use.
• C. Improved acoustics.
• D. No measurable effect.

Answer: (B)

Not monitoring static pressure means you can’t see the resistance air encounters as it moves through the ductwork, filters, dampers, and diffusers. That resistance determines how hard the fan must work to deliver the desired airflow. If you don’t track it, you miss when resistance increases (like a dirty filter or blocked vent) or when dampers are not set correctly, which leads to uneven, unbalanced airflow across zones. The fan ends up working harder or running longer to push air through higher resistance, which speeds wear on the fan motor and bearings and typically raises energy use. So the best consequence to expect is unbalanced airflow and excessive wear on fans. Reduced energy use isn’t expected because the lack of monitoring removes the ability to optimize and often causes inefficiencies; improved acoustics and no measurable effect are unlikely in real ducts systems.
