How It Works
From quote to check in hand
Verify your income tier
We help you check whether you qualify for the low- or moderate-income tier on Efficiency Maine's eligibility verification page. No income tier? You still qualify for the any-income rebate automatically.
Hire True North as your Registered Vendor
Rebates are only available through a Registered Vendor. We're on the Efficiency Maine vendor locator and hold every required certification.
We complete the install
We install per Efficiency Maine's Residential Heat Pump Installation Requirements Checklist. Every unit we install must be on the Rebate-Eligible Heat Pumps list.
We submit the claim form
We prepare the rebate claim form with all the technical details required. You sign it, and we submit within the 6-month window. Miss the deadline and the rebate is forfeited.
Efficiency Maine mails you a check
Rebates are issued as a check directly to you — not a discount at point of sale. Allow approximately 6 weeks for processing after the form is submitted.
Typical timeline: consultation to check in hand is 8 to 12 weeks, depending on install scheduling and Efficiency Maine processing time.
Honest Disqualifiers
Not for you if...
We'd rather tell you up front than waste your time.
Skip the rebate if any of these apply.
You have a natural gas utility account at the home
Efficiency Maine residential heat pump rebates are not available to homes with an existing natural gas account.
The heat pump will only be used for AC or shoulder seasons
Must be your primary heating system throughout the entire heating season. Efficiency Maine reserves the right to inspect.
You want a multi-zone unit (one outdoor, multiple indoor)
Multi-zone heat pumps are not rebate-eligible. Single-zone (one outdoor, one indoor) units are required.
You want a dual-fuel system (heat pump plus a fossil furnace)
Dual-fuel systems are not rebate-eligible and do not count toward sizing requirements.
The building has 3 or more housing units
Buildings with 3+ units route to the commercial program, not the residential rebate.
The building has a commercial electrical meter
All other building types with commercial metering are handled through the commercial program.
You're not the owner-occupant (low and moderate income tiers)
Owner-occupied principal residence is required to qualify for low- and moderate-income tiers.
You want to install it yourself
Installation must be performed by an Efficiency Maine Residential Registered Vendor.
The equipment isn't on the Efficiency Maine Rebate-Eligible Heat Pumps list
Every outdoor unit must appear on the Excel list Efficiency Maine maintains. We verify model numbers before quoting.

About the rebate program
How much is the rebate?
It depends on your income tier and system type.
- Ductless single-zone, any income: $1,000 per outdoor unit ($3,000 lifetime cap)
- Ductless single-zone, moderate income: $2,000 per unit ($6,000 lifetime cap)

A $500 limited-time bonus per housing unit is available for installs completed by December 31, 2026.
Do I have to pay upfront?
Yes. You pay True North for the installation. The Efficiency Maine rebate is a check that arrives approximately 6 weeks after we submit the claim form. It is not an instant rebate or a discount at point of sale.
Who fills out the paperwork?
We do. As a Registered Vendor, we prepare the rebate claim form with all the required technical details. You sign it, and we handle submission. For the supplemental low-income rebate, we submit the form and receive the payment directly on your behalf.
What if I have natural gas?
You are not eligible. Efficiency Maine residential heat pump rebates are not available to homes that have an existing natural gas utility account. If your home uses oil, propane, electric resistance, or wood heat, you can still qualify.
What is the difference between single-zone and multi-zone?
A single-zone heat pump connects one outdoor unit to one indoor unit. Single-zone systems are rebate-eligible. A multi-zone system connects one outdoor unit to multiple indoor units. Multi-zone systems are NOT rebate-eligible, though they can count toward the 80% peak heating load sizing rule. We will always clarify which configuration applies to your project before we quote.
How long does it take to get my rebate?
About 6 weeks after we submit the claim form. We must submit the form within 6 months of project completion or the rebate is forfeited. We track this deadline for every project we complete.
Can I get the rebate AND the federal tax credit?
Yes. The federal 25C tax credit stacks on top of every Efficiency Maine rebate. It covers 30% of qualifying heat pump costs, up to $2,000 per year. You claim it on IRS Form 5695 with your federal tax return. It is not refundable (reduces tax liability rather than generating a refund), but it resets annually.
What is a cold-climate heat pump?
A heat pump specifically rated to deliver efficient heating in extreme cold. Efficiency Maine only rebates the highest-performing units on its approved list. Many qualifying models operate efficiently at outdoor temperatures as low as -22 degrees Fahrenheit, and some perform down to -31 degrees Fahrenheit.
