Rebates in Sullivan County
South of Lebanon: Claremont’s mill-era housing stock, the Connecticut River towns, and the ridge communities around Croydon and Grantham.
Every town in Sullivan County is served by NHSaves, the joint efficiency program funded by Eversource, Liberty Utilities, Unitil and the New Hampshire Electric Co-op. Which of those four sends your bill does not change the rebate — the schedule is identical across all of them.
Income-qualified households in Sullivan County access free weatherization through Southwestern Community Services, which covers 100% of the cost rather than 75%. That program is separate from the utility rebates and has its own application and waiting list.
The 2026 schedule
| Upgrade | NHSaves pays | Notes |
|---|---|---|
| Air sealing & insulation | 75% of installed cost | Cap generally $6,000–$8,000; 100% for income-qualified households |
| Home energy assessment | $100 copay | $400–$600 value, plus $150–$400 of free direct-install items |
| Heat pump — from fossil fuel | $250/ton, max $1,250 | ENERGY STAR Cold Climate, R-32 or R-454B refrigerant |
| Heat pump — from electric resistance | $1,250/ton, max $6,250 | Pre-verification required before installation |
| Central air conditioner | $70/ton | ENERGY STAR certified |
| Wi-Fi thermostat | $85 | With a qualifying heat pump |
2026 installs must be completed by December 30, 2026 with rebate forms postmarked by January 30, 2027.
What Sullivan County houses usually need
The pattern across this county is consistent enough to state plainly: the building envelope before the equipment. Pre-war houses here have empty wall cavities, an unsealed attic plane hidden behind plaster, and a stone or brick foundation under a cellar that was never meant to be dry. Air sealing and insulation address all three, carry the largest rebate on the board, and shrink the heating system you eventually need to buy.

If you are comparing notes with a neighbour on the other side, note that the programs are not interchangeable — different percentages, different caps, and different contractor networks. See the Vermont schedule →
Figures checked July 2026. Rebate programs change their amounts, caps and equipment requirements during the year, and several are capped by available funding. Confirm the current offer with the program or your contractor before you sign anything.
