How can a homeowner improve their HERS score?

Improving a HERS score primarily pertains to enhancing the energy efficiency of a home. Installing energy-efficient appliances directly contributes to lowering energy consumption, which is a critical factor in determining the HERS score. These appliances are designed to use less energy while performing the same functions as standard appliances, leading to reduced energy bills and a lower carbon footprint.

In contrast, choices like painting the exterior, upgrading landscaping, or increasing window size might improve aesthetic appeal or comfort but do not significantly impact the home's overall energy performance. These actions do not address the core issues that influence energy efficiency in terms of HVAC systems, insulation, lighting, or appliance efficiency, which are pivotal in the HERS rating evaluation. Thus, the installation of energy-efficient appliances stands out as the most effective method for a homeowner to improve their HERS score.
