Efficiency Maine Heat Pump Rebates in 2026: How Much Can You Save?
Going ductless is more affordable than most Maine homeowners think — largely thanks to Efficiency Maine rebates.
Efficiency Maine rebates make heat pumps far more affordable than most homeowners expect. Here’s a plain-English breakdown of what’s available in 2026 and how to qualify. Always confirm current amounts at efficiencymaine.com before you buy — programs and funding change during the year.
2026 rebate amounts at a glance
Efficiency Maine offers tiered heat pump rebates based on household income. For a ductless mini-split (the systems we install), the rebate per qualifying outdoor unit is:
• Any income: $1,000
• Moderate income: $2,000
• Low income: $3,000
Lifetime rebate caps per home are up to $6,000 for moderate-income households and $9,000 for low-income households. Moderate income is generally an adjusted gross income up to $70,000 (single) or $100,000 (joint); low-income eligibility is based on MaineCare, HEAP, SNAP or TANF, or county median income.

The whole-home bonus
For eligible whole-home heat pump upgrades, Efficiency Maine has offered an additional $500 when the project is completed and the rebate claim is postmarked or emailed within the program window (through December 31, 2026). It stacks on top of the per-unit rebates above.
How to qualify for the top rebates
The largest rebates are reserved for systems that actually replace fossil-fuel heating as the home’s primary heat source. To reach the top tier, the heat pump generally needs to be designed to carry your whole home’s heating load — not just one room. Requirements usually include:
• A qualifying, listed heat pump model
• Installation by a Registered Efficiency Maine vendor
• Using the heat pump as your primary heating system
• A qualifying, listed heat pump model
• Installation by a Registered Efficiency Maine vendor
• Using the heat pump as your primary heating system
How the process works
1. Get an estimate from a Registered Vendor — that registration is what makes your project rebate-eligible.
2. Confirm the model qualifies and which income tier you fall into.
3. Install, then submit the rebate claim within the program window.
4. Many vendors handle the paperwork — or apply the rebate at the point of sale — so you don’t pay the full amount up front.

For the top rebate tiers, yes — it needs to serve as your primary heating system and be sized for your home.
