Common questions about Efficiency Maine rebates

Getting started

Maine’s energy efficiency program. It offers rebates and financing so homeowners can afford insulation, air sealing, heat pumps, and other home energy upgrades.

Efficiency Maine’s process is the same for every upgrade: verify eligibility, hire a registered vendor, complete the work, then submit a claim form. We handle the paperwork for you.

Yes, for every rebate. Evergreen is an Efficiency Maine Residential Registered Vendor for insulation, air sealing, and heat pumps.

Choosing the right insulation project

It helps. An energy audit shows exactly where your home is losing heat, so your insulation budget goes where it’ll make the biggest difference. Not required to get a rebate, but it’s a smart first step if you’re not sure what to prioritize.

Each part of your home loses heat differently, so they’re treated as separate projects, and now separate rebates too. Attic insulation is usually the biggest opportunity in older Maine homes. Wall insulation and basement insulation round out the rest of your home’s envelope. We’ll walk the whole house and tell you what’s worth doing first.

Yes. Spray foam qualifies for the same zone-based rebates as other insulation types, as long as the install meets Efficiency Maine’s requirements. The rebate is based on the square footage insulated in each zone, not the material used.

Eligibility and income tiers

Every Maine homeowner qualifies for at least the standard rebate. Low and moderate income households qualify for more. We’ll confirm your tier for you.

Low income means at least one household member receives HEAP, SNAP, TANF, or MaineCare. Moderate income means adjusted gross income up to $70,000 for individual filers or $100,000 for joint filers.

Single-family homes, two-unit duplexes, condos, and small mixed-use buildings qualify, as long as there’s no commercial electrical meter and the home is in Maine. Low and moderate income rebates require it to be your owner-occupied, year-round home. Any income rebates don’t require owner-occupancy.

Combining rebates and financing

Yes. Insulation and heat pumps are separate rebate programs, so you can claim both. We’ll help you plan the right order for your home and your budget.

Yes. Efficiency Maine’s Green Bank offers home energy loans for insulation and heat pump projects, and low and moderate income households can qualify for reduced rates. You’ll find the loan application here.

Each program has its own lifetime cap, and insulation and heat pumps are tracked separately. Only one rebate is paid per upgrade.

After you apply

Efficiency Maine asks for about six weeks to process a claim. We submit your paperwork right after your project wraps so the clock starts as early as possible.

Efficiency Maine rebates run on an annual funding cycle, so amounts and availability can shift. Moving sooner rather than later protects your rebate.

Start with a conversation. We’ll look at your home and tell you what makes the most sense and what you’ll qualify for.
