According to the U.S. Department of Energy, what is a simple method for homeowners to save on energy bills?

Air sealing is a highly recommended method for homeowners to save on energy bills, as it addresses a common issue of air leakage in homes. When air escapes or enters a residence through cracks and gaps in the building envelope, it can force heating and cooling systems to work harder than necessary to maintain a comfortable indoor environment. This increased workload directly translates to higher energy costs.

By sealing these leaks, homeowners can significantly improve the energy efficiency of their homes. This process not only reduces the need for heating and cooling, thereby lowering energy bills, but it also enhances the overall comfort within the home by preventing drafts and temperature fluctuations.

While upgrading windows, enhancing attic insulation, and installing solar panels are also effective methods for improving energy efficiency, they often require a more substantial investment of time and resources compared to air sealing. Air sealing is a simpler, cost-effective solution that can yield quick results, making it an accessible option for homeowners seeking immediate reduction in energy costs.
