Everything you need to know about HERS Ratings, energy testing, and MA Stretch Code compliance.
What is a HERS Rating?
A HERS (Home Energy Rating System) Rating is the nationally recognized standard for measuring a home’s energy efficiency. Developed by RESNET, the HERS Index scores homes from 0 (net zero) to 100+ (inefficient). Lower scores mean lower energy bills.
Is a HERS Rating required in Massachusetts?
Yes — HERS Ratings are required for Mass Save rebate programs, MA Stretch Code compliance (required in 300+ MA municipalities), and green building certifications like LEED and Energy Star. Most new construction in Massachusetts now requires a HERS Rating.
What is the MA Stretch Code?
The MA Stretch Code (based on IECC 2021) requires new residential construction to achieve a HERS score of 55 or below, pass a blower door test at 3.0 ACH50 or less, and pass a duct leakage test. Over 300 Massachusetts municipalities have adopted the Stretch Code.
How much does a HERS Rating cost in Massachusetts?
HERS Ratings in Massachusetts typically cost $350–$750 depending on home size and location. Contact us at 617-584-1809 for a free, no-obligation quote.
Do you serve all cities in Massachusetts?
Yes — HERS Rating Company serves all 351 cities and towns across Massachusetts, from Boston and the North Shore to Cape Cod, the Pioneer Valley, and the Berkshires.
How long does a HERS Rating take?
The on-site inspection takes 2–4 hours. You receive your certified HERS Rating report within 24 hours of the inspection.
What is blower door testing and is it required in Massachusetts?
A blower door test measures a building’s air tightness in ACH50. It is required for Mass Save air sealing rebates and MA Stretch Code compliance, which sets a maximum of 3.0 ACH50 for new residential construction.
What is duct leakage testing?
Duct leakage testing uses a duct blaster to measure conditioned air escaping through duct system leaks. It is required for all HERS Ratings and MA Stretch Code compliance certifications. Leaky ducts can waste 20–30% of conditioned air.
