Start with Efficiency Maine
Efficiency Maine’s residential heat-pump program has requirements for equipment, installation, and the home. Rebate levels depend on eligibility, and prior rebates can affect remaining benefits. Use the current program page and forms to establish what applies to your project.

Questions to resolve before installation
- Which income or household category applies, and what documentation is required?
- Does this home and project type qualify?
- Are the exact equipment model numbers and proposed system configuration eligible?
- Does the installer meet the program’s vendor requirements?
- Do previous incentives affect a lifetime limit or the amount remaining?
- Is approval required before work begins, and what are the submission deadlines?
- Who submits the claim, receives payment, and covers costs while it is processed?
- Can this incentive be combined with other assistance for the same project?
Keep written eligibility guidance, the itemized quote, model numbers, invoices, and submitted forms.
Utility rates are a separate decision
A utility rate option changes how electricity is billed; it is not an installation rebate. Compare the full year’s bill, including fixed charges, delivery and supply charges, seasonal usage, and any enrollment conditions.
Central Maine Power
Review CMP’s Electric Technology Rate and its comparison information. An optional rate does not guarantee that your household will save.
Versant Power
Review the Eco Rate options, current eligibility requirements, and rates for your service area directly with Versant Power.
If a municipal utility or cooperative serves your home, ask that provider about its current rates and any programs. Do not assume CMP or Versant options apply.
Federal tax guidance: watch the dates
The IRS states that the Energy Efficient Home Improvement Credit is unavailable for property placed in service after December 31, 2025. Older articles advertising a federal heat-pump tax credit may describe installations from earlier years.
For an earlier installation, consult the IRS’s rules for the relevant tax year and a tax professional about your situation. A tax credit and a state-administered rebate have separate requirements.
Before accepting a quote
Ask for the total installed price before incentives, each proposed incentive separately, and the expected amount you would pay if an application is denied. Treat eligibility as something to verify, rather than an assumed discount.
