Efficiency Maine Heat Pump Rebates
A more comfortable home may cost less to upgrade than you think. Efficiency Maine offers rebates for qualifying residential heat pump installations. The amount available depends on system design, income eligibility, equipment selection, previous rebates, and program requirements. Dave’s Heat Pumps helps homeowners navigate the technical and paperwork requirements, from planning through submission.
Current whole-home heat pump rebates
For qualifying projects where heat pumps will be the home’s primary heating system:
| Income category | Ducted whole-home system | Other eligible whole-home systems |
|---|---|---|
| Low income | $9,000 per housing unit | $3,000 per eligible outdoor unit; $9,000 lifetime limit |
| Moderate income | $6,000 per housing unit | $2,000 per eligible outdoor unit; $6,000 lifetime limit |
| Any income | $3,000 per housing unit | $1,000 per eligible outdoor unit; $3,000 lifetime limit |
Rebates are subject to lifetime limits per qualifying housing unit; previous heat pump rebates may reduce the amount available. The ducted whole-home amount applies to one or more eligible ducted heat pumps, while the other whole-home pathway uses eligible outdoor-unit counts. Dave’s confirms equipment and design requirements based on current Efficiency Maine rules before describing any projected rebate in a proposal.
Which systems qualify?
Efficiency Maine has different pathways for ducted whole-home systems and other whole-home heat pump configurations. Some important distinctions:
- Ducted whole-home systems must meet Efficiency Maine’s approved equipment, sizing and installation requirements. The eligible ducted system(s) must meet at least 100% of the home’s peak heating load. Dual-fuel heat-pump/furnace combinations are not eligible for the ducted rebate.
- For the other whole-home pathway, eligible single-zone equipment can receive a rebate, while multi-zone equipment may count toward heating capacity without receiving a per-unit rebate. Dual-fuel heat-pump/furnace combinations are excluded from that pathway.
- For that other pathway, new and existing heat pumps must meet at least 80% of the home’s peak heating load; the heat pumps plus eligible supplemental heat must meet at least 100%. Backup furnace/boiler and natural gas-account requirements also apply.
- An Efficiency Maine Residential Registered Vendor must perform the installation; other property, occupant and claim-timing rules apply.
Income-based rebate eligibility
Low-income and moderate-income customers may qualify for larger rebates after Efficiency Maine verifies eligibility. Qualifying benefit-program participation or adjusted gross income may be relevant. The best first step is to use Efficiency Maine’s official verification process rather than assume a household’s rebate category.

A limited-time 2026 rebate bonus
Efficiency Maine is currently offering an additional $500 heat pump rebate for eligible projects when BOTH the upgrade is completed AND the rebate claim is emailed or postmarked between March 1 and December 31, 2026, inclusive. This is a separate limited-time offer, not an automatic addition to every installation. Eligibility and the
current claim form must be confirmed with Dave’s before the project is finalized. The special single-wide mobile home rebate is excluded from this bonus.

What happened to the federal heat pump tax credit?
The federal Energy Efficient Home Improvement Credit (Internal Revenue Code Section 25C) previously offered a tax credit for qualifying heat pumps and certain related improvements. Under federal legislation enacted in 2025, Section 25C is not available for property placed in service after December 31, 2025. As a result, homeowners should not expect a Section 25C federal heat pump tax credit for a system placed in service in 2026.
Homeowners who placed eligible equipment in service on or before December 31, 2025 may wish to consult a qualified tax professional about whether a credit can be claimed for the applicable tax year. Dave’s Heat Pumps does not provide tax advice.

Other Efficiency Maine programs
Additional program pathways may apply to qualifying low-income households, single-wide mobile homes and multifamily buildings. These programs have their own eligibility conditions and should not be treated as additive to standard whole-home rebates without confirmation.

How to get started
Tell us about your home, your existing heating system, and your comfort goals. Dave’s evaluates system options, heating-load and whole-home requirements, and applicable rebate eligibility. We discuss the likely rebate pathway during project planning; Efficiency Maine—not Dave’s—makes the final rebate decision. For higher income-based rebate levels, please complete Efficiency Maine’s verification process early.
Dave’s handles the rebate paperwork
When Dave’s Heat Pumps installs a qualifying system, our team prepares the rebate claim paperwork and required heating-system design information. We review the program’s whole-home criteria and keep the paperwork with your installation job folder. At completion, your lead installer will request your signature on the applicable claim form. Our office then submits the claim to Efficiency Maine while we complete final invoicing and manufacturer product registration.
We take these steps to help customers submit a complete, timely claim. Rebate amounts, eligibility, approvals, recipient/payment arrangements, and processing times are determined by Efficiency Maine and cannot be guaranteed by Dave’s. Some income-based programs direct rebate payments to the registered vendor rather than the homeowner; your project paperwork will identify the applicable arrangement.
