What can be a result of poorly sealed ductwork?

Poorly sealed ductwork can lead to significant energy losses because air that is meant to flow through the ducts may escape into unconditioned spaces, such as attics or crawl spaces. This loss means that the HVAC system must work harder to achieve the desired temperature, resulting in increased energy consumption and higher utility bills. Additionally, when conditioned air is lost, it can lead to an imbalance in airflow, creating hot or cold spots in the building and reducing overall comfort. This compromised efficiency also can lead to increased wear and tear on the HVAC system, potentially shortening its lifespan.

In contrast, choices related to increased airflow, higher energy efficiency, or improved indoor air quality are not outcomes of poorly sealed ductwork and do not reflect the negative impacts that such a situation creates.
