Get a Free QuoteThe federal 25C tax credit is gone. Efficiency Maine rebates are still here — $1,000 to $3,000 per unit depending on income. NuWatt is a registered Efficiency Maine contractor and Mitsubishi Diamond installer with 600+ heat pump projects across Maine, the most oil-dependent state in America.
Section 25C expired December 31, 2025. The $2,000 federal heat pump credit is gone. But Maine homeowners still have Efficiency Maine rebates — $1,000 to $3,000 per unit, funded by the state trust, 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 Maine rebates are state trust-funded — completely separate from federal tax law. They are fully active in 2026 and have been running continuously since 2019.
$1,000/unit standard, $2,000/unit moderate-income, or $3,000/unit low-income. Up to 3 units per home (max $3,000-$9,000).
Every NuWatt quote shows your real cost after Efficiency Maine rebates— no phantom federal credits, no inflated "before incentive" prices designed to make the rebate look bigger.
We handle the entire Efficiency Maine application, including income verification for enhanced tiers, so your rebate is applied at point of sale.
Efficiency Maine has facilitated over 100,000 heat pump installations — one of the most successful state programs in the country. Here's exactly how the rebates work in 2026.
Available to all Maine residential customers. No income verification required. Applied at point of sale through registered Efficiency Maine contractors like NuWatt.
For households between 80-150% of Area Median Income. Requires income verification through Efficiency Maine. Applied at point of sale.
For households at or below 80% of Area Median Income. Requires income verification. Most generous heat pump rebate in New England per unit.
Separate rebate for ENERGY STAR heat pump water heaters replacing electric tank units. Can stack with whole-home HP rebates.
Maine has the highest oil heating dependency in the nation. The typical Maine household spends $3,000+/year on heating oil alone. Heat pumps cut that cost by 40-60% — and Efficiency Maine rebates make the conversion more affordable than ever.
Highest oil dependency in the US — double the New England average
~800 gallons/year typical = $3,050 annual heating cost
Heat pump in CMP territory: ~5,400 kWh at $0.27/kWh
Oil to heat pump savings plus AC included at no extra cost
We're not a general HVAC company that added heat pumps last year. We're a registered Efficiency Maine contractor and Mitsubishi Diamond installer with deep oil-to-HP conversion and cold-climate expertise.
Full registration means your rebate paperwork is handled by us from start to finish. Rebates applied at point of sale — no chasing rebate checks.
The highest tier of Mitsubishi partnership. Diamond status means priority equipment access, factory training, and extended warranty options unavailable to standard dealers.
Maine is the oil heating capital of America. We've completed hundreds of oil-to-heat-pump conversions across every climate zone in the state — from Portland (Zone 5, -1°F) to Caribou (Zone 6, -18°F).
Maine's older housing stock demands precise load calculations. Many pre-1950 homes have minimal insulation and unique heating challenges. We perform Manual J on every project — no guessing.
Our installation teams are NATE-certified, background-checked professionals trained on every brand we install. Same quality and accountability on every job.
Published pricing tiers, written line-item quotes, no hidden fees. We show your cost before and after Efficiency Maine rebates — with $0 for the expired federal credit.
Oil savings of ~$1,590/yr = payback in ~7.2 years. Plus you get central AC included — critical during Maine's increasingly hot summers.
Payback in ~3.5 years. The most affordable oil-to-HP conversion path in New England.
Maine spans two climate zones with design temperatures ranging from -1°F on the coast to -18°F in Aroostook County. The heat pump that works in Portland may not work in Caribou. Here's how we size systems for your specific location.
Our recommendation: Mitsubishi Hyper-Heat (-13°F) handles all conditions. Full oil replacement feasible.
Our recommendation: Mitsubishi Hyper-Heat or Fujitsu XLTH. Dual-fuel backup recommended for older, less insulated homes.
Our recommendation: Fujitsu XLTH (-15°F) required. Dual-fuel system strongly recommended. Oil backup for below -15°F.

Three ways to install a heat pump in Maine. Here's how they compare on the factors that matter most in 2026.
| Factor | NuWatt (Direct) | Local HVAC / Oil Co. | 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 Maine Expertise | Registered contractor — handles full rebate paperwork and income verification | Some participate, many skip Efficiency Maine due to paperwork burden | Rarely enrolled in Efficiency Maine; 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, Fujitsu XLTH to -15°F for Zone 6 | May install standard heat pumps that lose capacity below 5°F | Limited cold-climate experience; may default to resistance backup |
| Oil Boiler Integration | Dual-fuel specialists — HP + oil backup for northern ME homes | Oil HVAC contractors may resist HP adoption (protects their fuel business) | Limited experience with oil backup integration — rare outside New England |
| 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 brands chosen specifically for Maine's demanding climate — Zone 5 through Zone 6 extreme. Every unit we install is Efficiency Maine qualified and cold-climate rated.
Best for: Whole-home heating in ME, oil-to-HP conversions, Zone 5-6 cold-climate performance
Best for: Zone 6 extreme cold (Bangor north), supplemental heating, budget-conscious projects
Best for: Homes with existing ductwork, new construction, forced-air replacement
Every home is different. Here are the four most common heat pump projects we complete across Maine — with real costs and savings.
Over 60% of Maine homes still heat with oil at $3.82/gal — the highest oil dependency in the nation. A whole-home Mitsubishi Hyper-Heat system reduces heating costs by 40-60% while adding central cooling. Efficiency Maine offers rebates up to $3,000/unit for this exact project.
Maine propane costs $3.38/gal, and many rural homes lack natural gas access. Adding 1-3 ductless heat pump heads handles 60-80% of your heating load while your propane system covers the coldest nights. Lower propane usage, better comfort, and AC included.
For northern Maine homes where design temps reach -18°F, a dual-fuel setup is the smart play. The heat pump handles heating above ~0°F (80-90% of heating hours). Your oil boiler kicks in only during the coldest extremes. Dramatically reduces oil consumption without eliminating your safety net.
Most older Maine homes lack ductwork. Extending heat from an oil boiler to a new addition means expensive baseboard or radiant runs. A single ductless mini-split provides heating and cooling for the new space with zero ductwork. Clean, simple, efficient.

From first call to warm home in 3-6 weeks. We handle everything — including Efficiency Maine coordination.
In-home or virtual assessment. We evaluate your current heating system (oil, propane, electric), insulation, and home layout. You get a detailed proposal with Manual J calculations and real 2026 pricing.
Custom system design based on your climate zone, home size, and heating goals. We select the right brand and capacity — Mitsubishi for most of Maine, Fujitsu XLTH for northern regions.
We submit your Efficiency Maine rebate application, pull building permits, and order equipment. Income verification handled if you qualify for enhanced tiers.
Our own NATE-certified crews install outdoor unit(s), indoor heads or ducted air handler, refrigerant lines, condensate drains, and electrical connections. Oil boiler integration if dual-fuel.
System testing, homeowner training, thermostat setup, and final Efficiency Maine documentation. Your rebate is applied at point of sale — no waiting for a check.
Pair your heat pump with solar panels and offset the electricity your heat pump consumes. NuWatt is one of the few ME contractors that installs both — one crew, one project manager, one warranty.
Your utility determines your electricity rate, which directly impacts heat pump operating costs. Both utilities' customers qualify for the same Efficiency Maine rebates.
Even in Versant territory with higher rates, switching from oil to a heat pump saves $1,300+/year. The savings are real in both utility territories.
Full CMP vs. Versant Heat Pump Rate ComparisonHonest answers about heat pump installation in Maine — including what's changed for 2026.
Yes. NuWatt Energy holds Maine HVAC and electrical licenses, is a registered Efficiency Maine heat pump contractor, a Mitsubishi Diamond Contractor, and NATE-certified. We have completed over 600 heat pump installations across Maine, with deep expertise in oil-to-heat-pump conversions and cold-climate systems.
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 Maine rebates of $1,000-$3,000 per unit are still fully active and are not affected by the federal expiration.
Efficiency Maine offers $1,000 per heat pump unit for standard-income households (up to 3 units, $3,000 max). Moderate-income households (80-150% AMI) receive $2,000/unit ($6,000 max). Low-income households (under 80% AMI) receive $3,000/unit ($9,000 max). Income verification is required for the enhanced tiers. NuWatt handles the entire Efficiency Maine paperwork process.
Mitsubishi Hyper-Heat is our primary recommendation for most of Maine. It maintains 100% rated capacity at 5°F and continues operating down to -13°F — suitable for Zone 5 (Portland) through standard Zone 6 (Lewiston, Augusta, Bangor). For northern Maine (Caribou, Presque Isle) where design temps reach -18°F, we recommend the Fujitsu Halcyon XLTH, rated to -15°F.
A single-zone ductless mini-split costs $3,500-$6,500 installed. A multi-zone system (2-5 indoor units) costs $8,000-$18,000. A ducted central heat pump costs $12,000-$24,000. After Efficiency Maine rebates ($1,000-$3,000 per unit), a typical 3-zone oil-to-HP conversion costs $12,000-$15,000 out of pocket at standard income. Low-income households may pay as little as $6,000-$9,000.
In southern Maine (Portland, Biddeford, Kittery — Zone 5), yes. Modern cold-climate heat pumps operate efficiently down to -13°F, well below the -1°F to 5°F design temperatures along the coast. In central and northern Maine (Zone 6, design temps -7°F to -18°F), we recommend keeping your oil boiler as backup in a dual-fuel configuration. The heat pump handles 80-90% of heating hours, dramatically reducing oil consumption without eliminating your safety net for extreme cold snaps.
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. Maine's older housing stock (many pre-1950 homes with minimal insulation) makes Manual J especially critical. Without it, 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.
Your utility territory affects operating costs but not the equipment or installation price. CMP customers pay ~$0.27/kWh, while Versant customers pay ~$0.32/kWh — about 19% more per kWh. This means a heat pump in Versant territory (Bangor, northern/eastern Maine) costs roughly $270 more per year to operate than the same system in CMP territory (southern/central Maine). Both utilities' customers qualify for the same Efficiency Maine rebates.
A single-zone ductless mini-split installs in 1 day. A multi-zone 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 from September through November). NuWatt handles all permitting and Efficiency Maine paperwork.
NuWatt installs heat pumps across all of Maine including Greater Portland, Midcoast, Southern Maine, Lewiston/Auburn, Augusta/Waterville, Bangor, Downeast, and Northern Maine. We serve both CMP and Versant Power territories. Efficiency Maine rebates are available regardless of which utility serves your home.
