Massachusetts Home Energy Audit: What to Expect in 2026

A Massachusetts home energy audit through the MassSave program is a free, whole-home evaluation that shows you exactly where your home is losing energy — and how to fix it with state-backed incentives. In 2026, eligible homeowners served by Eversource or National Grid can schedule a no-cost assessment conducted by a certified energy specialist. The process is straightforward, pressure-free, and typically completed in a single visit. Here is exactly what to expect, step by step.

1. Schedule your free audit by calling MassSave or booking online through your utility’s website.
2. Prepare your home by gathering recent utility bills and ensuring the assessor can access your attic, basement, and mechanical systems.
3. A certified energy specialist visits your home and performs a comprehensive walkthrough from basement to attic.
4. The assessor runs a blower door test to measure air leakage and pinpoint where conditioned air is escaping your home.
5. Infrared thermography is used to identify hidden insulation gaps and thermal defects invisible to the naked eye.
6. The specialist reviews findings with you and explains which upgrades qualify for MassSave rebates and 0% financing.
7. You receive a written home energy report outlining prioritized recommendations and the incentives available to you at no obligation.

What Is a MassSave Home Energy Audit?

A MassSave energy assessment is a professional, whole-home evaluation conducted by a certified energy specialist — paid for through Massachusetts’s nation-leading MassSave program, which is jointly funded by your electric and gas utilities, including Eversource and National Grid. The goal is simple: identify exactly where your home is losing energy and money, then connect you with incentives to fix it.

During the audit, a trained assessor examines your home from basement to attic, testing insulation levels, air sealing, heating and cooling equipment, water heating systems, and even your lighting. Unlike a generic home inspection, an energy audit uses specialized diagnostic tools — including a blower door test and infrared thermography — to find the invisible problems that are silently inflating your utility bill every month.

The MassSave program has been helping Massachusetts homeowners improve home heating and cooling efficiency for over a decade, and in 2026 it remains one of the most generous state-level energy efficiency programs in the country. Best of all, it’s available to virtually every homeowner whose utility is an Eversource or National Grid customer.

Is the MassSave Audit Really Free? No Catches?

Yes — the home energy audit itself is completely free for eligible Massachusetts homeowners. There is no hidden fee, no obligation to purchase anything, and no sales pitch baked into the visit. This is one of the most common questions homeowners ask, and the answer is straightforwardly reassuring.

Here’s why it’s free: Eversource, National Grid, and other Massachusetts utilities are required by state law to fund energy efficiency programs for their customers. The MassSave program is the mechanism through which that funding reaches you. Your assessor is employed by or contracted through an independent Home Performance contractor — not a solar company, not an HVAC dealer — and their job is purely diagnostic.

That said, after the audit the assessor will discuss recommended upgrades with you. That’s not a sales pitch — it’s
