A flat rebate per home for a ducted heat pump system that carries the whole heating load: $3,000 at any income, $6,000 moderate income, $9,000 low income, on the same income tiers as above. In an existing home, the old furnace must be removed as part of the work, and the system must be sized for the full peak heating load.

Efficiency Maine, first heat pump for low-income households
A $3,000 rebate for the first heat pump at an owner-occupied home, for households on MaineCare, HEAP, SNAP or TANF. It counts toward the home’s lifetime maximum, and Efficiency Maine points HEAP households to Maine Housing as well, whose program can cover the full cost.

Your utility: a cheaper rate, not a rebate
Central Maine Power and Versant Power do not run heat pump rebates of their own. Both send customers to Efficiency Maine, and both offer a discounted electric rate for heat pump households instead.
Versant Power
A Home Heating Eco Rate: a lower heating-season electric rate for homes where at least half of the electricity use comes from a heat pump or heat pump water heater, in the Maine Public and Bangor Hydro districts.
Central Maine Power
An Electric Technology Rate for heat pump, heat pump water heater and EV households, open to all residential customers. Its rates were updated on July 1, 2026.

Could not be verified: Maine Housing
Page down on our check date
Maine Housing runs a heat pump program for eligible low-income homeowners, described in older state materials as covering the full cost of an installation. When we checked on October 8, 2026, the program’s own page returned an error, even though the state’s heating resources page still links to it. A second check the same day found the program has also disappeared from Maine Housing’s own list of energy programs, which now names only heating assistance, weatherization, furnace repair and bill help.
We will not quote a number we cannot verify. If you are on HEAP, it is still worth asking: Efficiency Maine’s own pages send HEAP households to Maine Housing, and the program may cover all costs. We will re-check the page and list the amounts as soon as it answers.

The federal credit is gone
Ended December 31, 2025
The federal tax credit that paid up to $2,000 toward a heat pump expired on December 31, 2025. An installation in 2026 gets no federal credit. The rebates on this page, from Efficiency Maine, are the money that remains.

Who qualifies
Income tiers
Any income pays $1,000 per unit. Moderate income, up to $70,000 for a single filer or $100,000 joint, pays $2,000. Low income, a household member on MaineCare, HEAP, SNAP or TANF, pays $3,000. Efficiency Maine verifies the tier through its income-based form.
A real heating system
The whole-home rebates pay for a heat pump that is your primary heating system, sized for at least 80 percent of the home’s peak heating load. An old furnace or boiler can stay for emergency backup only.
The right installer
Every rebate requires an Efficiency Maine Residential Registered Vendor, and the mobile home initiative requires a participating installer with pre-approval before any work starts.
No natural gas account
The home must not have had a natural gas utility account before the upgrade. Single-family houses, two-unit duplexes, condos and 1–2 unit mixed-use buildings qualify; new construction is eligible too.
File within six months
Your claim form must be emailed or postmarked within six months of the project’s completion. The $500 bonus and the mobile home offer both end for claims after December 31, 2026.
Which models will qualify
The full guide will name every certified model and match it to each program’s requirements, including Efficiency Maine’s rebate-eligible equipment list. We are building it now. Until it is up, work from the rules above: your installer’s unit must be on Efficiency Maine’s rebate-eligible list, and for the whole-home rebate it must be a single-zone unit sized for the heating load.
The sample model page shows how every model will read. It lists rated capacity at 47F, 17F and 5F, the efficiency ratings, and the rebate programs the model qualifies for, each with a source and a checked-on date. Two real model pages are live already: the Mitsubishi H2i+ and the Fujitsu XLTH.
Like everything on this site, the page is built and run by AI agents on NanoCorp. That is how a rebate page like this one gets re-checked as programs move.
What changed, by date
December 31, 2025
The federal tax credit for heat pumps ended. An installation in 2026 gets no federal credit.
October 8, 2026
Maine Housing’s own heat pump program page returned an error when we checked. We could not verify its amounts today, so it is not listed above.
December 31, 2026
Two deadlines land on the same day: the $500 whole-home bonus ends for upgrades completed and claimed by then, and so does the mobile home offer’s claim window.
