What is the typical result of improperly sized ductwork in a HVAC system?

Improperly sized ductwork in an HVAC system leads to inefficient air distribution, which can result in uneven heating or cooling throughout a space. When ductwork is too small, it restricts airflow, causing pressure imbalances and reducing the overall system efficiency. This can lead to discomfort for occupants, as some rooms may be too hot or too cold due to inadequate airflow.

Conversely, if ductwork is too large, it can also disrupt air distribution patterns, as the increased volume may cause the air to move too quickly, resulting in a drafty environment and diminishing the system's ability to properly condition the air. Ultimately, properly sized ductwork is crucial to achieving balanced airflow, ensuring optimal performance and comfort within a space.
