Get a Free QuoteThe federal 25C tax credit is gone. Efficiency Vermont rebates are still here — up to $3,000 for heat pump installation. NuWatt is a registered Efficiency Vermont contractor and Mitsubishi Diamond installer with 400+ heat pump projects across Vermont, including the coldest Zone 6 areas.
Section 25C expired December 31, 2025. The $2,000 federal heat pump credit is gone. But Vermont homeowners still have Efficiency Vermont rebates up to $3,000 — funded by your utility ratepayers, 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.
Efficiency Vermont rebates are funded through utility ratepayer charges — completely separate from federal tax law. They are fully active in 2026 and not affected by 25C expiration.
Up to $3,000 for qualifying heat pump systems. Income-eligible households may receive enhanced rebates. GMP, VEC, and Burlington Electric customers all qualify.
Every NuWatt quote shows your real cost after Efficiency Vermont rebates— no phantom federal credits, no inflated "before incentive" prices designed to make the rebate look bigger.
We handle the entire Efficiency Vermont application so your rebate is locked in before installation day. No paperwork surprises, no chasing checks.
Efficiency Vermont is one of the nation's most respected energy efficiency programs. Here's exactly how the heat pump rebates work in 2026 — no fine print surprises.
For whole-home heat pump conversion replacing fossil fuel (oil, propane, gas) as primary heating source. Must be cold-climate rated equipment.
For 1-2 zone ductless mini-split installations supplementing existing heating system. Great entry point for heat pump technology.
Income-eligible Vermont households may qualify for higher rebate amounts and additional weatherization assistance through Efficiency Vermont programs.
Separate rebate for ENERGY STAR heat pump water heaters replacing electric resistance or propane tank units. Stacks with heat pump rebate.
Vermont spans IECC Climate Zones 5 and 6 — with design temperatures ranging from -5°F in Brattleboro to -20°F in the Northeast Kingdom. Not every heat pump can handle this. Not every installer understands this.
Brattleboro, Bennington, Manchester
Standard cold-climate equipment handles this well. Mitsubishi Hyper-Heat at -13°F has 8°F of margin.
Rutland, Montpelier, Barre, Stowe
Requires premium cold-climate equipment. Hyper-Heat and Fujitsu -15°F models are ideal. Proper sizing critical.
St. Johnsbury, Newport, Island Pond
Our most demanding installations. We size for -20°F, use backup heat for extreme events, and insulate line sets. No compromises.
A "standard" heat pump loses 30-50% of its heating capacity at 17°F and may stop heating entirely below 5°F. Vermont regularly sees temperatures below 0°F from December through February. Installing a standard heat pump in Vermont is like putting summer tires on a car in January — it might work occasionally, but it will fail when you need it most.
Every heat pump NuWatt installs in Vermont is ENERGY STAR cold-climate certified, with a minimum operating temperature of -13°F or lower. For Zone 6 installations, we pair these with appropriately sized backup systems and perform detailed Manual J calculations using local TMY (typical meteorological year) data.
We're not a general HVAC company that added heat pumps last year. We're a registered Efficiency Vermont contractor and multi-brand cold-climate installer with deep expertise built for Vermont's extreme winters.
Registered contractor status means your rebate paperwork is handled by us from start to finish. No chasing rebate checks — we know the process inside and out.
We install Mitsubishi, Daikin, Bosch, and Fujitsu cold-climate heat pumps. Brand-agnostic recommendation means we match the right equipment to your home and load — not whichever brand we sell most.
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 Vermont's demanding climate zones.
Our installation teams are NATE-certified, background-checked professionals trained on every brand we install. Same quality and accountability on every job.
Vermont has the coldest design temperatures in our service area — down to -20°F in the NEK. 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 Efficiency Vermont rebates — with $0 for the expired federal credit.
Oil savings of ~$2,500/yr = payback in ~9 years. Plus you get central AC included — increasingly valuable as VT summers warm.
Vermont's electric rates are among the lowest in New England, making heat pumps especially cost-effective vs. oil ($3.80+/gal) and propane ($3.40+/gal). GMP's 75% renewable energy mix also means lower carbon footprint.

Three ways to install a heat pump in Vermont. Here's how they compare on the factors that matter most in 2026.
| Factor | NuWatt (Direct) | Local HVAC Contractor | National Chain |
|---|---|---|---|
| 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" |
| Efficiency VT Expertise | Registered Efficiency Vermont contractor — handles full rebate paperwork | Some participate, many skip Efficiency VT due to paperwork burden | Rarely enrolled in Efficiency Vermont; may not know about 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 VT Zones 5-6 (-5°F to -20°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 Vermont's Zone 5-6 conditions. Every unit we install is ENERGY STAR cold-climate certified and Efficiency Vermont rebate-eligible.
Best for: Whole-home heating in VT, oil-to-HP conversions, NEK extreme cold
Best for: Budget-conscious whole-home projects, supplemental heating, ski-area homes
Best for: Oil 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 Vermont — with real costs and savings.
~33% of Vermont homes still heat with oil. A whole-home Mitsubishi Hyper-Heat system eliminates the oil tank, removes combustion risk, and cuts heating costs by 40-60%. Vermont's cold climate demands proper cold-climate equipment rated to -13°F or below — no shortcuts.
Adding 1-2 ductless heat pump heads to your main living areas handles 60-80% of heating load. Your furnace kicks in only during deep cold snaps below -10°F. Lower fuel bills, better comfort, and AC included — a big deal during increasingly hot VT summers.
Vermont's Zone 6 areas (NEK, northern mountains) need systems designed for -20°F design temperatures. We install multi-zone Hyper-Heat systems with appropriately sized outdoor units that maintain heating capacity in extreme cold. No "southern spec" equipment.
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. Ideal for converted barns, ADUs, and finished basements common in VT.

Pair your heat pump with solar panels and eliminate both your oil bill and your electric bill. NuWatt is one of the few VT contractors that installs both — one crew, one project manager, one warranty.
Current annual costs
Oil: $3,800 + Electric: $1,800 = $5,600/yr
After heat pump only
Electric: $3,200/yr (HP replaces oil, electric bill rises)
After solar + heat pump
Electric: $400/yr (solar offsets most HP electricity)
Total annual savings
$5,200/year
93% reduction in energy costs. Payback in ~8-10 years for the combined system, with 25+ years of near-zero energy bills.
Honest answers about heat pumps in Vermont — including what the expired federal credit means for your 2026 project.
Yes. NuWatt Energy holds Vermont HVAC and electrical licenses and is a registered Efficiency Vermont heat pump contractor. We install multiple cold-climate brands (Mitsubishi, Daikin, Bosch, Fujitsu) across our New England service area, including extreme cold-climate installations in the Northeast Kingdom.
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, Efficiency Vermont rebates of up to $3,000 are still active and are not affected by the federal expiration.
Efficiency Vermont offers rebates of $1,000-$3,000 for qualifying heat pump installations depending on system type and configuration. Income-eligible households may qualify for enhanced rebates. All air-source heat pumps must be cold-climate rated. NuWatt handles the Efficiency Vermont rebate application process for you.
Mitsubishi Hyper-Heat is our primary recommendation for Vermont. Its hyper-heating technology maintains 100% rated capacity at 5°F and continues operating down to -13°F. Vermont has some of the coldest design temperatures in our service area — from -5°F in southern VT (Zone 5) to -20°F in the Northeast Kingdom (Zone 6). Mitsubishi's cold-climate performance is unmatched for these conditions.
A single-zone ductless mini-split costs $4,500-$7,500 installed. A multi-zone whole-home system (3-5 indoor units) costs $18,000-$32,000 before rebates. After Efficiency Vermont rebates ($1,000-$3,000), a whole-home system typically costs $15,000-$31,000 out of pocket. Oil-to-HP conversions see the fastest payback at 4-6 years due to high oil costs.
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. In Vermont's extreme cold, proper sizing is even more critical. NuWatt performs Manual J on every project.
Yes, with the right equipment. Modern cold-climate heat pumps like the Mitsubishi Hyper-Heat operate efficiently down to -13°F. Southern Vermont design temperatures are around -5°F, well within range. Northern Vermont and the NEK reach -20°F, which exceeds the -13°F rating, so we recommend keeping the oil system as backup for the coldest nights. In most of Vermont, a properly sized system handles 90-95% of annual heating load with the heat pump alone.
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 Efficiency Vermont rebate paperwork.
NuWatt installs heat pumps across all of Vermont including Southern Vermont (Brattleboro, Bennington), Central Vermont (Rutland, Woodstock), Burlington Metro, Montpelier-Barre, Upper Valley, and the Northeast Kingdom. We serve GMP, Vermont Electric Cooperative (VEC), and Burlington Electric Department territories.
No. Vermont is cold — Zone 5 in the south (-5°F) and Zone 6 in the north (-20°F) — but modern cold-climate heat pumps are engineered for these conditions. Mitsubishi Hyper-Heat maintains 100% capacity at 5°F and operates down to -13°F. Thousands of Vermont homes already heat primarily with heat pumps. The key is using properly rated cold-climate equipment and having it sized correctly with Manual J — not installing "southern" heat pumps that fail in January.
No high-pressure sales. No phantom federal credits. Just honest pricing, Efficiency Vermont rebate expertise, and systems built for the coldest winters in New England.
Serving all of Vermont: Burlington, Montpelier, Rutland, Brattleboro, St. Johnsbury, and everywhere in between.
