Which of the following best describes the long-term benefit of duct sealing and insulation?

Duct sealing and insulation significantly enhance the efficiency of a heating or cooling system, leading to substantial long-term benefits, particularly in reducing energy costs. When ducts are properly sealed and insulated, conditioned air is prevented from leaking out, which helps maintain the desired temperature in the home. This means that the heating or cooling system does not have to work as hard to compensate for the lost air, resulting in lower energy consumption.

Over time, the savings on energy bills can accumulate, making the initial investment in duct sealing and insulation well worth it. This long-term reduction in energy costs makes it a financially advantageous decision for homeowners seeking to improve their property's energy efficiency. The focus on efficiency also contributes to a reduced environmental impact, as less energy consumption typically corresponds to lower greenhouse gas emissions.

Other considerations, such as increased maintenance efforts or humidity levels, do not align with the intended benefits of duct sealing and insulation, as these improvements are designed to streamline system performance and enhance comfort.
