What is the result of undersized duct work?

Undersized ductwork leads to high noise levels, excessive air quantity, and elevated static pressures within the HVAC system. When ductwork cannot accommodate the required airflow, the result is often increased air velocity, which generates noise as air moves rapidly through constricted spaces. This can lead to the system working harder to push the air through the ducts, which creates static pressure. As a consequence, the inefficiency precipitated by these factors can lead to a host of issues, including discomfort due to variable airflow and difficulty in maintaining consistent temperatures throughout the space.

High static pressure can also strain the system components, potentially causing premature failure of fans and other parts due to the excessive strain placed on them. In contrast, properly sized ductwork ensures efficient airflow, balance within the system, and maintains comfort levels while minimizing noise and undue stress on the equipment.
