Maine leads New England in heat pump adoption with over 100,000 installations. Efficiency Maine offers $1,000-$3,000 per unit depending on income (max 3 units). The federal 25C tax credit is gone, but HEAR is partially active for mobile homes and affordable multifamily. Plus, the NE Heat Pump Accelerator ($450M, 5-state) launches in February 2026. This guide covers every rebate, how to qualify, and what to expect.
Efficiency Maine (Standard): $1,000/unit, max 3 units
Efficiency Maine (Moderate): $2,000/unit, max 3 units
Efficiency Maine (Low-Income): $3,000/unit, max 3 units
HEAR: Partially active — mobile homes + multifamily ONLY
Federal 25C: Expired December 31, 2025 — $0 available
NE Accelerator: $450M, 5-state, launching Feb 2026
Rebates applied at point of sale through registered Efficiency Maine contractors. HEAR only for mobile/manufactured homes and affordable multifamily — not standard single-family homes.
The $2,000 federal 25C heat pump tax credit expired December 31, 2025 under the OBBBA. No federal tax credit for residential heat pumps in 2026. Efficiency Maine rebates are now the primary incentive for most homeowners.
HEAR is only available in Maine for mobile/manufactured homes and affordable multifamily housing. Standard single-family homeowners are NOT eligible for HEAR. Eligible residents can receive up to $8,000 for heat pumps. This is a critical distinction — do not assume HEAR covers your home.
The $450M New England Heat Pump Accelerator launches February 2026 across 5 states. This initiative will standardize installations, reduce costs through bulk purchasing, and expand the trained contractor workforce. Maine, as the NE leader in heat pump adoption, is expected to benefit significantly.
Efficiency Maine offers three tiers based on household income. All tiers allow up to 3 units per home. Rebates are applied at the point of sale — your registered contractor deducts the rebate directly from your invoice.
Up to 3 units = $3,000 max
Up to 3 units = $6,000 max
Up to 3 units = $9,000 max
HEAT Loan Program: Efficiency Maine also offers the HEAT Loan program with low-interest financing for heat pump installations. This can be combined with your rebate to reduce or eliminate upfront costs. Ask your registered contractor about HEAT Loan eligibility.
The Home Electrification and Appliance Rebates (HEAR) program has limited availability in Maine. Unlike some other New England states, Maine has only activated HEAR for specific housing types.
Many websites incorrectly list HEAR as fully active in Maine. This is misleading. HEAR in Maine is only available for mobile/manufactured homes and affordable multifamily housing. If you live in a standard single-family home, you are NOT eligible for HEAR. Efficiency Maine rebates ($1,000-$3,000/unit) are your primary incentive.
Here are typical scenarios for Maine homeowners showing net cost after Efficiency Maine rebates. HEAR examples shown only for eligible housing types.
2 ductless mini-splits, $10,000 total
3 ductless units, $16,000 total
Low-income tier provides 56% reduction. HEAT Loan can cover remaining $7,000.
2 ductless units, $9,000 total
Mobile home residents can stack Efficiency Maine + HEAR for full coverage.

HEAR Rebates (Limited in Maine)
HEAR is only available for mobile/manufactured homes and affordable multifamily new construction in Maine. Standard single-family homes are NOT eligible.
No federal tax credit. Section 25C expired December 31, 2025. Efficiency Maine rebates are the primary incentive for Maine heat pump installations in 2026.
Visit the Efficiency Maine website or call their hotline to find registered heat pump contractors in your area. Only registered contractors can process the point-of-sale rebate.
Your contractor will assess your home, perform a load calculation, and recommend the right number of units and system type. Request a detailed quote showing the Efficiency Maine rebate deducted.
For the $2,000 moderate-income or $3,000 low-income tier, you will need income verification through a community action agency. Your contractor can guide you through this process.
Your contractor installs the system and submits the rebate application to Efficiency Maine. The rebate is applied at the point of sale — you pay the net cost, not the full amount.
If you live in a mobile/manufactured home or affordable multifamily housing, contact your community action agency about HEAR eligibility. This is a separate application from the Efficiency Maine rebate.
If you need financing for the remaining balance after rebates, ask about the Efficiency Maine HEAT Loan program. Low-interest rates are available for qualified energy efficiency improvements.
The New England Heat Pump Accelerator is a transformative $450 million, 5-state collaboration launching in February 2026. Maine, Vermont, New Hampshire, Massachusetts, and Rhode Island are partnering to dramatically expand heat pump adoption.
Efficiency Maine offers tiered rebates: $1,000 per unit for standard-income households, $2,000 per unit for moderate-income households, and $3,000 per unit for low-income households. You can receive rebates for up to 3 units per home. These are applied at the point of sale through registered Efficiency Maine contractors.
No. The federal Section 25C Energy Efficient Home Improvement Credit expired on December 31, 2025 under the One Big Beautiful Bill Act (OBBBA) signed July 4, 2025. There is no federal tax credit for residential heat pump purchases in 2026. Efficiency Maine rebates and HEAR (for eligible housing types) are the remaining incentives.
HEAR (Home Electrification and Appliance Rebates) is a federal program funded by the Inflation Reduction Act. In Maine, HEAR is PARTIALLY ACTIVE — it is only available for mobile/manufactured homes and affordable multifamily housing. Standard single-family homeowners are NOT eligible for HEAR in Maine. Eligible mobile home residents can receive up to $8,000 for heat pumps.
The $3,000/unit low-income rebate is available to households with income at or below 80% of Area Median Income (AMI). Efficiency Maine uses income verification through approved community action agencies. You can receive up to 3 units at $3,000 each ($9,000 total). A moderate-income tier ($2,000/unit) is available for households between 80-150% AMI.
Only if you live in a mobile/manufactured home or affordable multifamily housing. For those eligible housing types, you can stack Efficiency Maine rebates with HEAR rebates. Standard single-family homeowners can only access Efficiency Maine rebates. The total stacked amount cannot exceed the project cost.
The New England Heat Pump Accelerator is a $450 million, 5-state collaboration (Maine, Vermont, New Hampshire, Massachusetts, Rhode Island) launching in February 2026. It aims to standardize cold-climate heat pump installations across the region, reduce costs through bulk purchasing, and train contractors. Maine is expected to receive a significant share given its leadership in heat pump adoption.
Equipment must meet Efficiency Maine cold-climate heat pump specifications. This includes ductless mini-splits, multi-zone systems, ducted heat pumps, and hybrid systems from qualified manufacturers like Mitsubishi, Fujitsu, LG, Daikin, Carrier, and Bosch. Your registered Efficiency Maine contractor can confirm which models qualify.
Yes. You must use a contractor registered with Efficiency Maine to qualify for rebates. Registered contractors handle the rebate application and apply the discount at the point of sale. You can find registered contractors through the Efficiency Maine website or by calling their hotline.
Efficiency Maine allows rebates for up to 3 heat pump units per residential property. At the standard tier, this is $3,000 total ($1,000 x 3). At the moderate-income tier, $6,000 total ($2,000 x 3). At the low-income tier, $9,000 total ($3,000 x 3).
No. The Efficiency Maine rebate amounts ($1,000/$2,000/$3,000 per unit) are the same regardless of whether you are a Central Maine Power (CMP) or Versant Power customer. However, your electricity rate affects your ongoing operating costs — CMP customers pay about $0.27/kWh while Versant customers pay about $0.32/kWh.
Yes. Efficiency Maine offers a HEAT Loan program with low-interest financing for energy efficiency improvements including heat pumps. Many contractors also offer financing through third-party lenders. The Efficiency Maine rebate is deducted from the total cost before financing, so you only finance the net amount.
