Most Manchester addresses pay their electric bill to Eversource, which makes Eversource the front door to the biggest heat pump money available in New Hampshire this year. The utility sponsors NHSaves, the statewide efficiency program, and for qualifying cold-climate installs completed between March 23 and December 31, 2026, the enhanced tier pays $2,000 per ton of heating capacity. This guide walks through exactly what an Eversource customer can claim, how the payment actually arrives, and where applications go wrong.
What Eversource pays in 2026
The stack has three pieces, and they add rather than compete.
The per-ton rebate is the engine: $2,000 for every ton of heating capacity on a qualifying cold-climate heat pump, up from $1,250 per ton before March 23, 2026. A 3-ton system earns $6,000. A 4-ton system earns $8,000.
The New England Heat Pump Accelerator adds a flat $650 for each qualifying outdoor unit. One compressor, $650. A large layout with two compressors, $1,300.
The heat pump water heater rebate adds $750 when you swap a conventional water heater for a qualifying heat pump model, and bundling it into the same project is the cheap moment to do it since crews are already on site running condensate lines.
| Project | Per-ton money | Accelerator | Water heater | Total |
|---|---|---|---|---|
| 2.5-ton Wellington ranch | $5,000 | $650 | none | $5,650 |
| 4-ton Hallsville two-family | $8,000 | $650 | none | $8,650 |
| 3.5-ton Goffes Falls house, full package | $7,000 | $650 | $750 | $8,400 |
Tonnage comes out of a load calculation, the contractor's math against Manchester's design day near 1F, so the rebate is set by what your house needs rather than what anyone picks. The complete program picture, including the other sponsors, sits in our Manchester heat pump rebates guide.
Who qualifies
Eversource NH electric customers. That is the gate. The program checks the account paying the electric bill at the install address, so renters and landlords should sort out whose name the claim travels under before the paperwork starts. Liberty and Unitil customers claim the same $2,000 per ton through their own utility's lane of NHSaves. NH Electric Co-op members are on a different sheet entirely, standard $250 per ton up to $1,250 when displacing fossil heat, with a higher enhanced amount possible when replacing electric resistance, verified with the co-op before installation.
The equipment gate matters just as much. The heat pump must be a qualifying cold-climate model, the kind that holds heating output deep below zero, and current qualifying equipment runs on R-454B. Ask for the specific model's listing in writing. Our guide to the best heat pumps for Manchester cold explains what those listings measure.
The installer gate closes the set: licensed professional work, with utilities steering jobs toward their network contractors. A cousin-with-a-gauge-set install can void the whole claim.
How the money actually arrives
NHSaves runs downstream, meaning the rebate pays out after installation. Two versions exist in practice.
The plain version: you pay the contractor in full, submit the application with the invoice, model numbers, and documentation, and the check arrives some weeks later. You float the rebate amount in the meantime.
The friendlier version: established shops discount the invoice by the rebate up front, then collect the reimbursement themselves. On a 4-ton job that is $8,650 you never have to front. Ask every bidder which model they run before you sign, because on a five-figure project the answer changes your cash flow by thousands.
Either way, keep everything. Invoice with model and serial numbers, the load calculation, the commissioning report. Stalled applications are almost always missing-document stories rather than ineligible-equipment stories.
What kills an application
The rejection patterns repeat, and every one is preventable at the quoting stage.
Non-qualifying equipment leads the list. An ordinary heat pump, or older-refrigerant stock a shop wants to move, fails the cold-climate requirement and takes the entire rebate down with it.
Indefensible sizing comes second. Oversizing to inflate the per-ton payout gets flagged in review, and even when it slips through, the oversized machine short-cycles for its whole service life. The load calculation should reference Manchester's actual design conditions on paper.
Stale-playbook contractors round it out. The federal 25C and 25D credits expired on December 31, 2025, and the HEAR program is gone with them. A 2026 proposal that leans on federal credits to sweeten its math is leaning on money that no longer exists, and it tells you how current the rest of that shop's knowledge is. The vetting questions that surface all of this are collected in our guide to choosing an HVAC contractor in Manchester.
What the process looks like start to finish
The clean path runs in six steps. A contractor visits and runs the load calculation against the design day. You get a written proposal naming the qualifying model, the tonnage, and the rebate math line by line. You confirm the shop's rebate model, upfront discount or downstream check. Install happens, one to three days for most Manchester houses. Commissioning follows, the documented performance verification that proves the system delivers what the listing claims. Paperwork goes in, with the invoice, model numbers, load calculation, and commissioning report attached, and the money moves.
Homeowners who get burned usually skipped step two or step three. The proposal that never named the model, or the handshake about who claims the rebate, is where five-figure projects grow four-figure surprises.
Why the timing pressure is real
The enhanced tier has a fixed close: December 31, 2026. The install has to be completed in the window, and completed means commissioned, documented, and done rather than contracted. Crews across Southern New Hampshire book out weeks deep once furnace-failure season starts, so a homeowner who starts quoting in November is gambling the difference between $2,000 and whatever comes next per ton on someone else's schedule. Nobody can promise the next tier matches this one; the last transition moved the rate by $750 a ton, and on a 4-ton house that swing is $3,000.
Shoulder season is the professional's answer. Quote in spring or summer, install before the fall rush, claim inside the window with months to spare, and walk into winter with the system already commissioned.
Running your own number
The estimate takes one input you probably know and one you can get. Tonnage guess: roughly one ton per 600 to 1,000 square feet depending on the age and tightness of the house, so a 2,000 square foot North End colonial likely lands between 2.5 and 3.5 tons. Multiply by $2,000, add $650 per outdoor unit, add $750 if the water heater joins the project. A real load calculation replaces the guess with a number the program will accept, and that is the number worth planning around.
