What can be a consequence of poor insulation in ductwork?

Poor insulation in ductwork can lead to increased energy loss. When ducts are not properly insulated, conditioned air—whether heated or cooled—can escape into unconditioned spaces, such as attics or crawl spaces. This loss of air means that the HVAC system must work harder to maintain the desired temperature in the living area, ultimately resulting in higher energy consumption. This inefficiency not only raises energy bills but can also lead to uneven heating or cooling throughout the home.

In insulated ducts, the temperature of the air remains more consistent, allowing the HVAC system to operate more efficiently. Therefore, having well-insulated ductwork is essential for energy efficiency, cost savings, and overall comfort in a building.
