What kind of situation might require duct modification?

Duct modification is often necessary when there are changes in building layout or usage. This is because alterations in a building’s structure or purpose can significantly affect airflow and ventilation requirements. For instance, if a space is reconfigured—such as converting an office into an open workspace or adding new rooms—existing ductwork may no longer effectively distribute heated or cooled air, leading to areas becoming uncomfortably hot or cold.

In such cases, modifications to the duct system may include resizing, adding new ducts, or rerouting existing ones to ensure that the HVAC system operates efficiently and meets the new requirements of the space. Ensuring proper airflow and temperature control aligns with the intended use of the area, fostering a more comfortable and energy-efficient environment.

While obsolete HVAC systems, seasonal adjustments, or routine maintenance checks can require attention, they do not typically necessitate duct modifications in the same way that changes in building layout or usage do.
