What type of maintenance action can help prevent energy loss through ducts?

Sealing gaps in ductwork is a critical maintenance action that helps to prevent energy loss. When there are gaps or leaks in the duct system, conditioned air can escape into unconditioned spaces, such as attics or crawl spaces, thereby reducing the efficiency of heating and cooling systems. By sealing these leaks, or using mastic sealants and metal tapes designed for ducts, you can ensure that air travels only to the designated areas of a building, leading to more efficient operation, reduced energy use, and lower utility bills. This proactive measure not only improves energy efficiency but also enhances indoor comfort by maintaining consistent temperatures throughout the living space.

Other actions, like removing insulation, would likely result in increased energy loss by exposing the ducts to temperature fluctuations. Ignoring leaks only exacerbates energy waste, and overworking the system puts unnecessary stress on HVAC components, leading to higher operating costs and potential system failures. Thus, sealing gaps is the most effective choice for reducing energy loss through ducts.
