Qualify as low-income and Efficiency Maine's top tier stacks with the federal HEAR program for mobile homes — often enough to cover a full system.
Efficiency Maine treats a household as low-income if a member is enrolled in a qualifying assistance program, or income is at or below the county low-income threshold for the household size.
Qualifying low-income mobile homes can have up to three Seville cold-climate heat pumps installed at no cost. The Efficiency Maine + HEAR stack is applied for you — no paperwork to chase.
Best for: households already on MaineCare, HEAP, SNAP, or TANF.
Want the highest-efficiency Keen units? BRF Services or Maine Energy Services offer them at a fixed $75/month for 60 months, 0% interest — a predictable payment, no teaser rate.
Best for: maximum efficiency with a set monthly cost.
| Income tier | Per outdoor unit | Lifetime cap per home |
|---|---|---|
| Low income | $3,000 | $9,000 |
| Moderate income | $2,000 | $6,000 |
| Any income (no verification) | $1,000 | $3,000 |
Applies to qualifying single-zone cold-climate outdoor units on Efficiency Maine's list, up to three per home.
Maine deploys its federally funded HEAR program to the highest-energy-burden housing first. Single-family manufactured (mobile) homes occupied by income-eligible residents are one of two priority categories. That lets a mobile home layer HEAR on top of the Efficiency Maine rebate:
| Source | Low-income mobile home |
|---|---|
| Efficiency Maine (3 units × $3,000) | up to $9,000 |
| HEAR (mobile-home heat pump rebate) | up to $8,000 |
| Combined | up to ~$17,000 |
MaineCare, HEAP, SNAP, or TANF enrollment is the fastest route to low-income status.
Call BRF Services or Maine Energy Services. Only a Registered Vendor can process the rebate.
Your installer verifies income with Efficiency Maine first — this must happen before the work.
Up to 3 free Seville units, or top-tier Keen at $75/month, 0% for 60 months. The installer applies rebates; you pay the net.
A registered Maine installer will size the system, confirm your rebate tier, and quote the net cost — at no charge.
