Get a Free QuoteThe federal 25C tax credit is gone. NHSaves utility rebates are still here — up to $500/ton for air-source and $750/ton for geothermal heat pumps. NuWatt is a certified NHSaves contractor and Mitsubishi Diamond installer serving all of New Hampshire.
Section 25C expired December 31, 2025. The $2,000 federal heat pump credit is gone. But New Hampshire homeowners still have NHSaves utility rebates — up to $500/ton for ASHP and $750/ton for GSHP — funded by your utility, not the IRS.
Section 25C — the $2,000 energy efficiency tax credit for heat pumps — expired December 31, 2025. If you install a heat pump in 2026, your federal credit is $0.
Any contractor still quoting you a federal tax credit for a heat pump is either uninformed or dishonest. Period.
NHSaves utility rebates are funded through your utility bill via the Systems Benefit Charge — completely separate from federal tax law. They are fully active in 2026.
All four NH utilities participate: Eversource, Liberty, Unitil, and NHEC. Rebates range from $400-$500/ton for ASHP and up to $750/ton for geothermal.
Every NuWatt quote shows your real cost after NHSaves rebates — no phantom federal credits, no inflated "before incentive" prices designed to make the rebate look bigger.
We handle the entire NHSaves application for whichever utility serves your home, so your rebate is locked in before installation day.
New Hampshire has four electric utilities, each with their own NHSaves rebate amounts. Here's exactly what each utility pays for heat pump installation in 2026 — no fine print surprises.
| Utility | Electric Rate | Coverage | ASHP Rebate | GSHP Rebate | HPWH Rebate |
|---|---|---|---|---|---|
| Eversource | $0.25/kWh | ~71% of NH | Up to $500/ton | Up to $750/ton | $500-$750 |
| Liberty | $0.24/kWh | ~6% of NH | Up to $450/ton | Up to $750/ton | $500-$750 |
| Unitil | $0.26/kWh | ~11% of NH | Up to $500/ton | Up to $750/ton | $500-$750 |
| NHEC | $0.22/kWh | ~12% of NH | Up to $400/ton | Up to $750/ton | $400-$600 |
We're not a general HVAC company that added heat pumps last year. We're a certified NHSaves contractor and Mitsubishi Diamond installer with deep cold-climate expertise across New Hampshire's Zone 5 and Zone 6 conditions.
Full certification across all four NH utilities — Eversource, Liberty, Unitil, and NHEC. Your rebate paperwork is handled by us from start to finish, regardless of which utility serves your home.
The highest tier of Mitsubishi partnership. Diamond status means priority equipment access, factory training, and extended warranty options unavailable to standard dealers. Critical for NH winters.
We perform a full Manual J heating and cooling load calculation on every installation. No "rule of thumb" guessing — your system is precisely sized for your home, your insulation level, and NH climate zones 5-6 (design temps -5°F to -15°F).
Our installation teams are NATE-certified, background-checked professionals trained on every brand we install. Same quality and accountability on every job.
New Hampshire has design temperatures from -5°F (Nashua, southern NH) to -15°F (North Country). Every system we install is rated for these conditions. We don't install "southern" heat pumps that fail in January.
Published pricing tiers, written line-item quotes, no hidden fees. We show your cost before and after NHSaves rebates — with $0 for the expired federal credit.
Oil savings of ~$2,200/yr at $3.60/gal = payback in ~10 years. Plus you get central AC included — saving $4K+ vs. separate AC installation.
New Hampshire is the second most oil-dependent state in the U.S. for home heating (~45% of homes). At $3.60/gal, a typical 2,000 sq ft home spends $3,000-$4,500/year on oil heat alone.
A properly sized heat pump cuts that cost by 40-60% while adding AC you didn't have before. The oil tank comes out, the combustion risk disappears, and your home value increases.

Three ways to install a heat pump in New Hampshire. Here's how they compare on the factors that matter most in 2026.
| Factor | NuWatt (Direct) | Local HVAC Contractor | National Chain (e.g. One Hour) |
|---|---|---|---|
| Post-25C Honesty | Transparent: $0 federal credit for heat pumps in 2026 | May still quote $2,000 "federal tax credit" from expired 25C | Sales reps often reference expired 25C or vague "federal incentives" |
| NHSaves Expertise | Certified NHSaves partner — handles full rebate paperwork for all 4 utilities | Some participate in NHSaves, many skip it due to paperwork requirements | Rarely enrolled in NHSaves; may not know about NH utility rebates |
| Manual J Load Calc | ACCA Manual J on every project — right-sized system guaranteed | Often uses "rule of thumb" sizing — leads to oversized systems | Varies; some use Manual J, many use square-footage estimates |
| Cold Climate Expertise | Hyper-Heat systems rated to -13°F, designed for Zone 5-6 (-5°F to -15°F) | May install standard heat pumps that lose capacity below 5°F | Limited cold-climate experience; may default to dual-fuel |
| Installation Crews | Own W-2 employees — NATE certified, background-checked | Usually own crews (strongest advantage of local HVAC) | Subcontracted labor, varying quality and accountability |
| Pricing Transparency | Published pricing tiers, written quotes with line items | Pricing varies widely; often no published rates | Opaque pricing, high-pressure in-home sales presentations |
| Warranty & Service | 12-year compressor + 10-year parts + 2-year labor warranty | Manufacturer warranty only; labor warranty varies | Good manufacturer warranties but service via call centers |
We carry three premium brands chosen for their cold-climate performance in New Hampshire's Zone 5-6 conditions. Every unit we install is ENERGY STAR cold-climate certified and NHSaves eligible.
Best for: Whole-home heating in NH, oil-to-HP conversions, cold-climate performance
Best for: Budget-conscious whole-home projects, supplemental heating, additions
Best for: Gas/propane furnace replacement using existing ducts, homes with central air
Every home is different. Here are the four most common heat pump projects we complete across New Hampshire — with real costs and savings.
~45% of NH homes still heat with oil at $3.60/gal. A whole-home Mitsubishi Hyper-Heat system eliminates the oil tank, removes combustion risk, and cuts heating costs by 40-60%. NHSaves offers the highest rebates for oil-to-HP conversions — up to $500/ton ASHP depending on your utility.
NH propane runs $3.20-$3.50/gal. Adding 1-2 ductless heat pump heads to your main living areas handles 60-80% of heating load. Your propane furnace kicks in only during deep cold snaps below -10°F. Lower propane bills, better comfort, and AC included.
When your central AC dies, replace it with a ducted heat pump instead of another AC-only unit. Same ductwork, same thermostat — but now you get efficient heating too. Bosch IDS is our go-to for this project type in NH homes with existing ductwork.
Extending ductwork to a new addition costs $5,000-$10,000 and requires an oversized furnace. A single ductless mini-split provides heating and cooling for the new space with zero ductwork. Clean, simple, efficient — and NHSaves rebates still apply.

From first call to warm home in 3-6 weeks. We handle everything — including NHSaves coordination for your specific utility.
In-home or virtual assessment. We evaluate your current heating system (oil, propane, or electric), insulation, and home layout. You get a detailed proposal with Manual J calculations and real 2026 pricing.
We schedule your NHSaves home energy audit through your utility. The auditor inspects your home and identifies insulation and air-sealing needs. This step maximizes your rebate eligibility.
Custom system design, equipment ordering, and building permit applications. We coordinate any recommended weatherization work from the energy audit.
Our own NATE-certified crews install outdoor unit(s), indoor heads or ducted air handler, refrigerant lines, condensate drains, and electrical connections.
System testing, homeowner training, thermostat setup, and NHSaves rebate submission to your utility. Rebate checks typically arrive within 6-8 weeks.
Pair your heat pump with solar panels and eliminate both your oil/propane bill and your electric bill. NuWatt is one of the few NH contractors that installs both — one crew, one project manager, one warranty.
New Hampshire spans two IECC climate zones with very different design temperatures. Getting this right is the difference between a heat pump that works and one that fails in January.
Nashua, Manchester, Concord, Seacoast, Monadnock Region
Lakes Region, Upper Valley, North Country, White Mountains
Many NH homes were built before modern insulation codes. Older homes in Manchester, Concord, and the Lakes Region often have inadequate insulation in attics and walls. A Manual J calculation accounts for your actual insulation level — not an assumption. This prevents oversizing (which wastes money) and undersizing (which leaves you cold). NuWatt performs Manual J on every project, calibrated to your specific climate zone.
Honest answers about heat pump installation in New Hampshire — including what's changed for 2026.
Yes. NuWatt Energy holds New Hampshire HVAC and electrical licenses, is a certified NHSaves heat pump contractor, a Mitsubishi Diamond Contractor, and NATE-certified. We have completed over 800 heat pump installations across New Hampshire and New England.
No. The Section 25C energy efficiency tax credit expired on December 31, 2025. There is $0 federal credit available for heat pump purchases in 2026. Any contractor quoting you a $2,000 federal tax credit is referencing an expired program. However, New Hampshire NHSaves utility rebates of up to $500/ton for air-source heat pumps remain fully active in 2026.
NHSaves rebates vary by utility. For air-source heat pumps: Eversource offers up to $500/ton, Liberty up to $450/ton, Unitil up to $500/ton, and NHEC up to $400/ton. Ground-source (geothermal) heat pumps qualify for up to $750/ton. Income-eligible households may receive enhanced rebates. NuWatt handles the entire NHSaves paperwork and rebate application process for all four utilities.
Mitsubishi Hyper-Heat is our primary recommendation for New Hampshire. Its hyper-heating technology maintains 100% rated capacity at 5°F and continues operating down to -13°F — critical for NH design temperatures that range from -5°F (southern NH) to -15°F (North Country, Zone 6). Fujitsu Halcyon is an excellent secondary option rated to -15°F at a lower price point.
A single-zone ductless mini-split costs $4,500-$7,000 installed. A multi-zone whole-home system (3-5 indoor units) costs $18,000-$30,000 before rebates. After NHSaves rebates ($2,000-$5,000 depending on system size and utility), a whole-home system typically costs $15,000-$25,000 out of pocket. Oil-to-HP conversions see the fastest payback at 5-7 years given NH oil prices.
Manual J is the ACCA-standard method for calculating your home's exact heating and cooling load. It accounts for insulation, window type, orientation, air leakage, and local climate data. Without Manual J, installers guess using "square footage rules" that typically result in oversized systems — which short-cycle, waste energy, and fail to dehumidify properly. NuWatt performs Manual J on every project, calibrated to NH climate zones 5 and 6.
Yes. Modern cold-climate heat pumps like the Mitsubishi Hyper-Heat operate efficiently down to -13°F. Southern NH design temperatures are around -5°F, well within the operating range. Even in the North Country (design temp -15°F), a properly sized system with backup electric resistance can handle the coldest nights. We recommend keeping your oil system as emergency backup during the first winter for peace of mind, then decommissioning if you are comfortable.
A single-zone ductless mini-split installs in 1 day. A multi-zone whole-home system takes 2-4 days depending on the number of indoor units and whether electrical panel upgrades are needed. From signed contract to installation, lead time is typically 2-4 weeks (longer during peak season). NuWatt handles all permitting and NHSaves paperwork.
Yes. For homes without existing ductwork (common in older NH homes with radiators or baseboard), we install ductless mini-split systems from Mitsubishi and Fujitsu. For homes with existing ductwork (gas/propane furnace or central AC), we install ducted heat pump systems from Bosch and Mitsubishi that connect to your current ducts. We also handle hybrid configurations where ductless heads serve certain zones while a ducted system serves others.
NuWatt installs heat pumps across all of New Hampshire including Southern NH, the Seacoast, Manchester, Concord, the Lakes Region, Upper Valley, Monadnock Region, and North Country. We serve all four NHSaves utility territories: Eversource, Liberty, Unitil, and NHEC. NHSaves rebates are available regardless of which NH utility serves your home.
