In HVAC design, proper airflow is the lifeblood of comfort and efficiency. A common point of failure, however, is neglecting . When fans are undersized, air doesn't move; when they are oversized, energy is wasted, and ducts become noisy.

If the blower fan cannot overcome this pressure, the airflow (CFM) drops, leading to poor heating/cooling, frozen coils, or burned-out blower motors. 2. Components of an ESP Calculation
