HERS Score Explained
The HERS (Home Energy Rating System) Index is the standard for measuring a home’s energy efficiency. It is a nationally recognized system and homes are inspected by an independent, certified home rater. And when it comes to the HERS score, remember, the lower the score, the better! Check out this video, “Ask for the HERS Index Score!” to learn more or visit the interactive HERS Index demonstration here.
