Higher energy consumption and costs is a common consequence of poor duct sealing because leaks in the ductwork allow conditioned air to escape into unconditioned spaces, such as attics or crawlspaces. This results in the heating or cooling system working harder to maintain the desired indoor temperature, thereby increasing energy usage. As a result, you may notice higher utility bills as the system runs longer to compensate for the lost air. A well-sealed duct system minimizes air loss, leading to improved energy efficiency and reduced costs.

Improper duct sealing can also lead to other issues, such as discomfort in temperature regulation and problems with indoor air quality; however, the most direct and notable financial impact comes from the increase in energy consumption.
