What can result from oversized ductwork in an HVAC system?

Oversized ductwork in an HVAC system can lead to reduced air velocity and poor temperature control due to the characteristics of air movement within larger ducts. When ducts are oversized, the air has a larger pathway to travel through, which can cause it to move more slowly, resulting in reduced air velocity. This slower air movement can prevent the effective distribution of conditioned air throughout the space, leading to temperature imbalances and discomfort in certain areas.

Inadequate air velocity can also mean that air doesn't reach all parts of a room effectively, which can create hot or cold spots. Consequently, the ability of the HVAC system to maintain set temperatures in different rooms diminishes, resulting in poor overall temperature control. This highlights the importance of proper duct sizing in ensuring that air is distributed efficiently and evenly, ultimately affecting comfort levels within the living or working environment.
