Get a Free QuoteNHSaves offers rebates, not loans. There is no 0% financing program in NH. Your options are personal loans (7.5-15% APR), HELOC (6.5-9.5%), contractor financing (9.9-18%), or cash. NH has no income tax, so you cannot deduct interest on a state return. Section 25C is dead — $0 in 2026.
Many NH homeowners assume NHSaves offers financing like Massachusetts' HEAT Loan. It does not. NHSaves is a rebate-only program — you pay for the installation, then receive a check weeks later.
Requirement: Replacing oil, gas, or propane heating
Refrigerant: R-32 or R-454B only (R-410A banned from NHSaves list)
Requirement: Replacing electric resistance heating (baseboard, wall units)
Processing: 4–8 weeks after installation
You must pay the full installation cost upfront (or finance it). The NHSaves rebate check arrives 4-8 weeks after your NHSaves-qualified contractor submits the completion paperwork. Plan your financing around this delay — the rebate does not reduce your initial outlay.
Each option has trade-offs. We calculated total cost on a $10,000 system (3-ton, standard rebate $750) to show the real difference.

New Hampshire is one of the few states with no personal income tax. This is great for your paycheck but means you cannot deduct any loan interest at the state level.
You cannot deduct loan interest on a state tax return — there is no state return.
HELOC interest may be deductible on federal return for home improvements, but only if you itemize. Standard deduction is $15,700 (single) / $31,400 (married) in 2026.
The federal 25C energy efficiency tax credit expired December 31, 2025. It was worth up to $2,000 for heat pumps. It is $0 in 2026.
The NHSaves rebate is a cash rebate mailed to you after installation. It does not reduce your tax liability. It reduces your net cost directly.
In states with income tax (like Massachusetts at 5% flat), a HELOC at 7% effectively costs ~6.65% after the state tax deduction on interest. In New Hampshire, that HELOC costs the full 7% because there is no state deduction. This narrows the advantage of HELOC vs. personal loan by about 0.3-0.5% — making personal loans relatively more competitive in NH than in neighboring states.
The bottom line: NH homeowners should focus on the actual APR and total interest cost rather than hoping for tax deductions. The math is simpler when there is no tax benefit to calculate.
Based on current 2026 rates. Personal loan at 10% / 5yr. HELOC at 7.5% / 10yr. Contractor at 12% / 7yr.

If you've heard about Massachusetts' 0% HEAT Loan, you might wonder why NH doesn't have something similar.
Massachusetts funds its 0% HEAT Loan through utility system benefit charges (SBC) and green bond programs. NH's utility SBC is lower, and the state has historically prioritized lower utility bills over subsidized financing programs. NHSaves allocates its funding to direct rebates rather than interest rate buydowns. This is a policy choice, not a funding shortage.
Only NHSaves network contractors can process your rebate. Ask for itemized quotes that show equipment model, tonnage, and refrigerant type. Verify R-32 or R-454B — R-410A is banned from NHSaves.
Standard ($250/ton) for oil/gas/propane replacement. Enhanced ($1,250/ton) for electric resistance replacement. This determines your net cost and how much you need to finance.
Total installed price minus expected NHSaves rebate. Remember: you pay full price upfront and receive the rebate 4-8 weeks later. Finance the full amount, not the net amount.
Above 740: Best rates on personal loans and HELOCs. 670-739: Good rates, most options available. Below 670: Contractor financing may be your best bet, though at higher APR.
Get quotes from your bank/credit union (HELOC), 2-3 online lenders (personal loan), and the contractor's financing partner. Compare total interest paid, not just monthly payment.
Watch for deferred interest (you owe ALL interest if not paid in promo period), dealer fees (3-15% hidden in equipment price), and prepayment penalties. Ask the contractor: "Is there a dealer fee?"
When your NHSaves rebate check arrives (4-8 weeks post-install), put it toward your loan principal immediately. This saves you interest on that amount for the remaining term.
Many contractor financing offers advertise "0% interest for 18 months." This is almost always deferred interest, not a true 0% APR promotion. The difference is critical:
Interest accrues from day one but is "deferred." If you have any remaining balance when the promo period ends, ALL accrued interest is added to your balance retroactively. On a $10,000 balance at 22% APR, that is $3,300 in back-interest hitting your account on month 19.
No interest accrues during the promotional period. If you have a remaining balance when the promo ends, interest starts accruing only on the remaining amount going forward. This is what credit cards sometimes offer. It is rare in contractor financing.
Ask your contractor explicitly: "Is this deferred interest or true 0% APR?" Get the answer in writing.
No. Unlike Massachusetts (which had a 0% HEAT Loan), NHSaves does not offer any financing program. NHSaves provides rebates only — $250/ton standard (max $1,250) or $1,250/ton enhanced (max $6,250) for electric resistance replacement. You must arrange your own financing through personal loans, HELOC, or contractor financing.
No. New Hampshire has no personal income tax, so there is no state tax return to deduct interest on. You may be able to deduct HELOC interest on your federal return if the loan is used for home improvements and you itemize deductions, but this only applies at the federal level.
A single-zone ductless mini-split costs $3,500–$7,000 installed. A multi-zone system costs $8,000–$15,000. A whole-home ducted system costs $12,000–$22,000. After the NHSaves standard rebate ($250/ton, max $1,250), net cost for a typical 3-ton system is about $8,750–$13,750. The enhanced rebate ($1,250/ton) is only for electric resistance replacement.
Cash is cheapest if you have savings. HELOC offers the lowest interest rate (6.5–9.5%) but puts your home at risk. Personal loans (7.5–15%) are fastest and don't require equity. Contractor financing is convenient but typically the most expensive. Avoid credit cards unless you have a 0% intro APR card and can pay in full within the promo period.
No. The Section 25C energy efficiency credit expired December 31, 2025. It is worth $0 in 2026. The only financial incentive for NH homeowners is the NHSaves rebate program.
Yes. The NHSaves rebate is paid after installation regardless of how you finance the purchase. You can use a personal loan, HELOC, or contractor financing to cover the upfront cost, then apply the rebate toward your loan principal or keep it as savings.
Typically 4–8 weeks after your NHSaves-qualified contractor submits the completed paperwork. The contractor handles the rebate application. You receive a check by mail or direct deposit.
No. New Hampshire does not have a Property Assessed Clean Energy (PACE) program for residential properties as of 2026. Some states offer PACE, which attaches clean energy improvement costs to your property tax bill, but NH has not adopted this program.
