NHSaves is New Hampshire's utility-funded energy-efficiency program — run jointly by Eversource, Liberty, Unitil, and the NH Electric Co-op — and it offers rebates for qualifying heat pumps and ductless mini-splits statewide. The exact eligible equipment and rebate amount are set by the program and change over time, so the reliable move is to confirm current terms before buying. The rebate is part of the cost math, but the system still has to be right-sized and cold-climate first.
What NHSaves is
NHSaves is the shared energy-efficiency program of New Hampshire's regulated utilities — Eversource, Liberty, Unitil, and the New Hampshire Electric Co-op. It's funded through the utilities and available statewide, and it offers rebates and incentives for qualifying high-efficiency equipment, including air-source heat pumps and ductless mini-splits. For a Keene homeowner, it's the main rebate path that applies to a ductless install.
Because it's a utility program rather than a one-time promotion, the structure is stable but the specifics — eligible equipment, efficiency tiers, and amounts — are reviewed and updated over time. That's why this guide describes how it works rather than quoting a dollar figure that would go stale.
What generally qualifies
Rebates generally apply to qualifying high-efficiency heat pumps and ductless mini-splits that meet the program's efficiency thresholds and are installed to program requirements. Efficiency is usually the gate — units that hit the program's SEER2 and HSPF2 (or cold-climate) criteria qualify, while lower-efficiency equipment may not. The exact eligible list and tiers are set by NHSaves and change, so eligibility is confirmed against the current terms, not an old flyer.
The practical upshot for a New Hampshire home: the cold-climate, high-efficiency unit you'd want for the winter anyway is usually the one that qualifies. The rebate tends to reward the right equipment rather than push you toward something you wouldn't otherwise pick.
How the process works
In broad strokes: you install a qualifying system, then the rebate is claimed against the equipment and the completed install, with documentation of the model and the work. Keeping the model numbers, the spec sheet, and the invoice together is what makes the claim smooth. Many installers handle or help with the paperwork as part of the job, so it isn't a separate errand for the homeowner.
Because the program reviews equipment and terms periodically, the cleanest path is to confirm eligibility for your specific system before the install, so there are no surprises at claim time. We do that as part of the quote — you'll know what your home is likely to qualify for before anything's ordered.
Fitting the rebate into the math
A rebate lowers the net cost of the right system, which can meaningfully improve the payback against an oil or propane bill. But it shouldn't change the fundamentals: the system still has to be right-sized off a Manual-J load calculation and rated cold-climate for a Cheshire County winter. A rebate on an oversized or under-rated unit is still the wrong unit at a discount.
So the order of operations is: size and spec the right system, then factor the rebate into the net cost — not the reverse.
