Meet Dominic Zammuto
Owner & Lead HERS Rater
When you call Home Energy Efficiency Consultants, you speak directly to Dominic — a licensed contractor, certified HERS rater, and lifelong construction professional.
The story
Built from the ground up — literally
Dominic Zammuto did not come to energy consulting through a classroom. He grew up on construction sites. His father is a builder, and from an early age Dominic was learning the trade the way it was meant to be learned — with his hands, watching how buildings actually go together.
After earning his Unrestricted Construction Supervisor License (CSL) and spending over 25 years managing construction projects across Massachusetts — including more than 250 new construction builds — Dominic recognized a gap in the industry. Builders needed a HERS rater who actually understood construction.
So he built Home Energy Efficiency Consultants from scratch — not as a consultant who happens to know a little about buildings, but as a construction professional who happens to be one of the most experienced certified HERS raters in Massachusetts.
Today, over 15,000 HERS ratings completed across all 351 Massachusetts cities and towns. When you call, Dominic answers. 24/7. That is the standard he has held since day one.
“When you call us, you get me — not a salesperson, not a call center. I know your project, I know Massachusetts energy code, and I will get you what you need to close out your permit.”— Dominic Zammuto, Owner & Lead HERS Rater
