Heat pump vs. gas furnace — Close call
New Hampshire's electricity-to-gas price ratio works out at 4.0-to-1. At these prices the two land near each other on running cost, which puts the decision on installation cost, whether your AC also needs replacing, and how cold your winters get.
Below roughly 3.5-to-1 a heat pump usually wins on running cost; above roughly 5-to-1 a furnace may be cheaper through winter. How that comparison works · run it with these rates
State averages from the U.S. Energy Information Administration (electricity, gas), pulled 2026-08-16. Real bills vary substantially by utility within a state, and by rate plan within a utility — check a recent bill for your own numbers before relying on any of this. The heat pump verdict above follows from these averages, so it moves if your rates differ.
What's different in New Hampshire
NHSaves is the statewide program, funded by electric and natural gas ratepayers and delivered jointly by Eversource, Liberty Utilities, New Hampshire Electric Cooperative and Unitil. It covers home energy audits and weatherization, heat pump rebates, appliance rebates and income-eligible assistance.
One specific rule worth checking before you buy: NHSaves states that from 1 January 2026, heat pump models using R-410A refrigerant are no longer eligible for rebates. Older-refrigerant units are exactly the stock a contractor may be keen to clear at a discount, so confirm the model you are quoted still qualifies — the rebate can be worth more than the discount.
The whole-house Home Energy Performance route, starting with an audit, is generally the larger opportunity here than any single piece of equipment.
Check with the administrator before you sign anything. Program budgets run out, terms change without notice, and most require approval before work starts — a rebate you apply for afterwards is usually a rebate you don't get. Treat this page as a starting point for your own call, not as confirmation that you qualify. We last checked these programs on August 16, 2026.

Your own utility is worth checking separately — utility rebates are often the largest remaining incentive and rarely appear in any central listing.
Not tax advice
Everything here is general information gathered from public sources. It is not tax, financial or engineering advice, and it cannot account for your utility, your income, your equipment or your return. Energy prices are state averages that move; program terms and budgets change without notice. Confirm anything you plan to budget around directly with the program administrator, your utility and a licensed professional before you commit money.
