A whole-home heat pump in Manchester can qualify for a rebate this year. That sentence would have been fantasy two years ago.
The catch is that the money follows rules. Miss the equipment list, botch the sizing, or hire the wrong installer, and the check never comes. Here is how the whole stack works for a Manchester address, with the math done for real houses in real neighborhoods.
Where the money comes from now
New Hampshire's home energy rebate program is not open as of 2026-10-07 (https://www.energy.nh.gov/funding-opportunities/funding-opportunities-homeowners/home-electrification-and-appliance-rebates). Check your state energy office for current rebates. Everything you can claim in 2026 flows through New Hampshire's ratepayer-funded NHSaves program and the regional accelerator. You should read the rest of their proposal with that in mind.
NHSaves is sponsored by the state's electric utilities. In and around Manchester that means Eversource for most addresses, with Liberty and Unitil serving their own territories and the NH Electric Co-op covering members on its own schedule. The program is statewide, so a homeowner in Hooksett follows the same rulebook as one in Downtown Manchester.
The core payout is simple multiplication.
Capacity is not a number you pick. A contractor runs a load calculation against the coldest weather Manchester actually sees, and the house tells you what it needs. Ask for a room-by-room load calculation before you compare quotes.
The adder stacks on top of the per-ton money rather than replacing it.
Crews are already opening walls and running condensate lines, so bundling the water heater is usually the cheapest moment you will ever have to do it.
Three Manchester scenarios, fully priced
Numbers land better on actual houses.
The Bedford scenario deserves a second look. On a multi-zone project, the rebate can change the conversation from someday to this fall. The per-ton structure rewards houses with honest, documented heat loss, and larger homes carry larger loads.
NH Electric Co-op runs its own schedule
Co-op members outside the three big utilities work from a different sheet. Members replacing electric resistance heat as their primary source can qualify for a higher enhanced amount, and the co-op wants that verified before installation, so call them before you sign anything.
What disqualifies an application
The rejection reasons repeat across the state. Every one of them is avoidable.
The equipment has to be a qualifying cold-climate model. These machines hold their heating output on the coldest nights, and the program list exists because ordinary heat pumps cannot. Ask for the specific model's listing, in writing.
The sizing has to be defensible. Manchester's coldest day is real winter cold, and the load calculation should say so on paper. Oversizing to inflate the per-ton payout gets flagged, and an oversized machine short-cycles for its whole service life even if the rebate sneaks through.
The refrigerant will be R-454B on current equipment. That is the standard your installer should name without prompting.
The installer has to be a licensed professional, and several utilities want their network contractors on the job. A handyman install can void the entire claim.

How the money actually moves
NHSaves pays downstream, meaning after installation. In the plain version, you pay the contractor, submit the paperwork with the invoice and equipment documentation, and the rebate arrives as a check. Plenty of established shops offer the friendlier version: they discount the invoice by the rebate amount up front and collect the reimbursement themselves. Ask which model a contractor uses before you sign, because it decides whether you float the rebate amount for a few weeks.
Keep copies of everything. The invoice showing model numbers, the load calculation, the commissioning report. Applications stall on missing documents far more often than on ineligible equipment.
Timing the window
The enhanced tier has a hard edge: December 31, 2026. If the math above works for your house, the expensive mistake is waiting for January to think about it.
