Get a Free QuoteFrom your first call to Efficiency Maine to getting your heat pump running: the standard path takes 3-5 weeks with the rebate applied at point of sale. Income-eligible households need 2-4 extra weeks for pre-approval. Here is the step-by-step timeline so you know exactly what to expect.
3-5 Weeks
Call EM, get quotes, install, rebate applied at point of sale. Rebate check (if separate): 4-8 more weeks.
4-8 Weeks
Extra 2-4 weeks for income verification and pre-approval before scheduling installation.
1-2 Weeks Approval
Loan application processed alongside contractor scheduling. Payments start after installation.
This is the most common path. The $1,000 per unit standard rebate requires no income verification. Most homeowners complete this process in 3-5 weeks from first call to working heat pump.
Call 866-376-2463 or visit efficiencymaine.com. Discuss your project scope, ask about current rebate availability, and get a list of registered contractors in your area.
Tips
Contact 2-3 registered contractors for quotes. They will assess your home, recommend system size and placement, and provide a detailed proposal including the Efficiency Maine rebate.
Tips
Select your contractor and schedule the installation. If applying for a PACE loan, submit the application through your contractor at this stage.
Tips
A single-zone mini-split typically takes 4-8 hours. Multi-zone systems take 1-2 days. The contractor installs the outdoor unit, indoor head(s), runs refrigerant lines, and connects electrical.
Tips
The contractor submits the completed installation paperwork to Efficiency Maine. If rebate was applied at point of sale, you already have the discounted price. If not, Efficiency Maine processes the rebate.
Tips
If the rebate was not deducted from your invoice, Efficiency Maine processes the rebate application and mails a check. Typical processing time is 4-8 weeks after receiving complete documentation.
Tips
Key Takeaway: Most people pay the reduced price upfront.
The vast majority of Efficiency Maine registered contractors apply the rebate at the point of sale. You pay the discounted price ($2,500-$5,500 for a single-zone instead of $3,500-$6,500). The contractor handles the Efficiency Maine reimbursement. The 4-8 week rebate check timeline in Step 6 only applies if you use a contractor who does not handle point-of-sale rebates — which is uncommon.
Households below 150% AMI can qualify for enhanced rebates ($2,000-$3,000 per unit). The process adds 2-4 weeks for income verification before contractor selection. This extra step is worth it — the enhanced rebate can double or triple your savings.
Call Efficiency Maine (866-376-2463) to begin the income verification process. They will explain which income tier you may qualify for and what documentation is needed.
Submit required documentation: recent tax returns, pay stubs, or proof of enrollment in qualifying assistance programs (MaineCare, SNAP, LIHEAP, etc.). Can be submitted online, by mail, or by fax.
Efficiency Maine reviews your income documentation and determines your tier. Low-income (below 80% AMI) qualifies for $3,000/unit. Moderate-income (80-150% AMI) qualifies for $2,000/unit.
Once approved, you receive a pre-approval letter specifying your enhanced rebate amount. Provide this to your contractor before scheduling installation.
Same as the standard path: get quotes, choose a contractor, schedule installation. The contractor applies the enhanced rebate at point of sale. Low-income households may also qualify for weatherization bundling.
If using a PACE loan at the 0% rate, payments begin after installation. For low-income households, the remaining cost after enhanced rebate and weatherization matching may be very small ($0-$2,000).
Primary Documentation (one of):
Automatic Qualification (if enrolled in):
Enrollment in these programs automatically qualifies you for the low-income tier.
The Efficiency Maine PACE loan does not require you to pay upfront and wait for reimbursement. It works in parallel with the contractor scheduling process.
Application
Submitted with contractor selection (Week 2-3)
Contractor submits PACE application on your behalf
Approval
1-2 weeks after application
Runs parallel to installation scheduling
Funding
At installation
PACE funds the project minus the EM rebate
First Payment
30-45 days after installation
Monthly payments at 0-4.99% APR begin
Bottom line: PACE adds no extra time to the process. Loan approval happens while your contractor is scheduling the installation. You never pay the full price out of pocket.
Contractor availability varies significantly by season. Planning ahead can save you weeks of waiting.
1-2 weeks
Moderate demandBest time to schedule. Good availability. Install before summer cooling season.
2-3 weeks
Moderate-High demandContractors busier with AC work. Still good availability for HP installs.
3-6 weeks
Peak demandHighest demand. Everyone wants heat pumps before winter. Book early.
2-4 weeks
Moderate demandInstallation is fine in winter, but outdoor temps below 0F may delay line set work.
Pro tip: If you want heat pumps running by October heating season, start the process in June or July. This gives you 3 months of buffer even during peak demand. Starting in September means you may not be installed until November or later.
