If you own a home in Maine and you’re thinking about a heat pump, the single most valuable thing you can do this year is understand the Efficiency Maine rebate program. We see homeowners leave thousands of dollars on the table because nobody walked them through it. This is that walkthrough.
The short version
Efficiency Maine pays cash rebates on qualifying heat pump installations. The amount depends on your household income and the type of system you install. Rebates range from $1,000 on a single outdoor unit all the way up to $9,000 for a whole-home ducted installation in a low-income household. Stack the federal tax credit on top and you’re looking at another $2,000 back at tax time.
The rebate is a check, not a point-of-sale discount. It comes directly from Efficiency Maine about six weeks after the paperwork is submitted.
The three income tiers
Everything in the program flows from which income tier your household falls into.
Low income. Someone in your household is enrolled in MaineCare, HEAP, SNAP, or TANF. This is the highest-paying tier.
Moderate income. Your adjusted gross income is up to $70,000 single or $100,000 joint. Mid-tier rebate amounts.
Any income. Default tier. No income verification required. Every Maine homeowner qualifies for at least this level.
You don’t have to apply for the low or moderate tier. If you qualify, we verify eligibility on your behalf at the Efficiency Maine portal before we start the paperwork. If you don’t qualify, you still get the any-income rebate automatically.
Ductless mini-splits vs. ducted central
The rebate structure splits by system type.
On ductless mini-splits, you get paid per outdoor unit. Low-income households receive $3,000 per outdoor unit up to a lifetime cap of $9,000 per housing unit. Moderate-income households receive $2,000 per outdoor unit up to $6,000. Any-income households receive $1,000 per outdoor unit up to $3,000.
On ducted central systems, the rebate is a flat amount regardless of how many units are installed. Low income gets $9,000. Moderate income gets $6,000. Any income gets $3,000.
There’s a limited-time bonus running through December 31, 2026: an extra $500 per housing unit for whole-home heat pump upgrades, excluding single-wide mobile homes and the supplemental low-income rebate.
The five-step process
- Verify your income tier. We help you check eligibility on the Efficiency Maine verification page. Takes about five minutes.
- Hire a Registered Vendor. Rebates are only available through Registered Vendors. We’re on the Efficiency Maine vendor locator and hold every required certification.
- Complete the install. Every unit we install is on the Rebate-Eligible Heat Pumps list, and we install to the Residential Heat Pump Installation Requirements Checklist.
- Submit the claim form. We prepare the rebate claim form with all the required technical details. You sign, we submit within the six-month window. Miss the deadline and the rebate is forfeited.
- Check arrives. Efficiency Maine mails you a check. Allow approximately six weeks after the form is submitted.
The three things that kill rebates
Over the years we’ve watched homeowners lose rebates for three reasons.
First, they hired a contractor who wasn’t a Registered Vendor. The program is strict: no Registered Vendor, no rebate. It doesn’t matter how good the install is.
Second, they bought a unit that wasn’t on the Rebate-Eligible Heat Pumps list. Not every cold-climate heat pump qualifies. We check the list before we quote you.
Third, they missed the six-month submission window. Paperwork has to be submitted within six months of the install date. We handle this on every job so it never becomes an issue.
What we do for you
We verify eligibility, check the unit against the Rebate-Eligible list, install to spec, and file the paperwork. You sign one form and six weeks later you get a check. That’s it.
