Executive summary

Mass Save bases eligibility on household income, residence type (1–4 unit homes primarily), and participation in certain public assistance programs; qualifying unlocks enhanced, often no‑cost, weatherization and heating/cooling incentives while non‑qualifying households still can receive basic no‑cost assessments and products [1] [2]. Applicants verify income through Mass Save’s online tool or local Community Action Program (CAP)/Fuel Assistance agencies to access turnkey services, enhanced rebates (including large heat‑pump incentives), and bill discounts in some cases [3] [4] [2].

1. How the program defines who’s eligible

Mass Save separates standard offers from “income‑eligible” enhanced offers: the program is open to residential customers of participating utilities but the highest level of benefits — no‑cost weatherization, turnkey services, and enhanced heating/cooling rebates — is reserved for households that meet specific income guidelines or already participate in fuel‑assistance programs like HEAP [1] [2] [3].

2. Income thresholds and real‑world examples

Eligibility is tied to household size and gross annual income bands rather than a single cutoff; Mass Save publishes tables and provides an Online Income Qualification Tool so households can check whether they fall into the income ranges that trigger enhanced offers — for example, the program cites that a family of four with household income up to $126,000 may qualify for no‑cost offers in some categories [3] [5].

3. Verification: documentation, tools and partners

Full income verification is required to unlock enhanced offers; applicants can use the Mass Save online qualification portal or work with local CAP agencies, fuel assistance offices, or call dedicated phone lines for help — the process may involve providing proof of income or participation in HEAP and can lead to a referral to the local utility for bill discounts [3] [2] [6].

4. What income‑eligible households can receive

Income‑verified customers can receive a managed package that includes a no‑cost Home Energy Assessment followed by free insulation and air‑sealing, equipment replacements (refrigerators, washers, dehumidifiers, window ACs), health‑and‑safety remediation, and in many cases up to full coverage for heat pumps or large rebates [1] [5] [4].

5. Renters, multifamily buildings and property rules

The core income‑eligible program is designed primarily for one‑ to four‑unit homes; multifamily buildings with five or more units may qualify if at least half the residents meet income eligibility, and renters are encouraged to coordinate upgrades with landlords — eligibility and who gets the work depends on building ownership, meter arrangements, and sponsor rules [6] [1] [7].

6. What happens if a household doesn’t qualify by income

Households that do not meet income thresholds still have access to Mass Save’s no‑cost Home Energy Assessment and some free efficiency products, and they can pursue standard incentives, rebates or the HEAT loan for upgrades — the program explicitly points applicants to other non‑income services when enhanced offers aren’t available [1] [7].

7. Where the money and administration come from, and why it matters

Mass Save’s income‑eligible work is jointly administered by utility program sponsors and community partners (CAP agencies, LEAN, third‑party vendors listed by sponsor), meaning priorities balance state energy‑efficiency goals with utilities’ administration and contractors’ delivery; those institutional relationships shape which measures are funded and which vendors perform work [1] [8] [5].

8. Practical next steps and contact points

Prospective applicants should start with the Mass Save Online Income Qualification Tool or call the Mass Save line to schedule a Home Energy Assessment; those who receive fuel assistance or HEAP should contact their local Fuel Assistance Agency or the Massachusetts Heat Line for referrals and to secure utility bill discounts tied to program enrollment [3] [2] [6].

9. Caveats, competing narratives and limitations in available reporting

Public materials emphasize broad access and example thresholds but steer users to online tools and local agencies for precise income tables — third‑party summaries sometimes simplify eligibility as “60–80% of state median income,” which may mislead because Mass Save uses detailed household‑size tables and program‑specific ranges; reporting documents the mechanics (tools, CAP partners, documented examples) but does not provide a single up‑to‑date statewide income table in these excerpts, so applicants must verify via Mass Save’s eligibility pages or by phone [9] [3] [1].
