The term "duct leakage" specifically refers to the loss of conditioned air through holes or gaps in ductwork. This phenomenon occurs when air intended to be delivered to a room escapes through unintended openings, which can result in decreased efficiency of heating and cooling systems. It ultimately leads to higher energy consumption as the system has to work harder to make up for the lost air, which can cause an increase in utility bills and reduced indoor air quality.

In a well-sealed duct system, air is distributed effectively without significant loss, which is crucial for maintaining comfortable and consistent indoor conditions. Understanding duct leakage is essential for implementing energy-saving measures and improving the overall functionality of HVAC systems.
