Rebate Snapshot
The Duke Energy insulation rebate may help eligible customers lower the upfront cost of qualifying attic insulation or insulation and air sealing work. The most important thing to know is that Duke Energy does not appear to use one universal insulation rebate across every state it serves.
Florida customers may see the rebate through Duke Energy Florida’s Home Energy Improvement program. North Carolina and South Carolina customers may see insulation-related rebates through Duke Energy’s Smart $aver / Insulate and Seal program. Amounts, contractor rules, audit requirements, and application steps can vary by utility territory, so homeowners should confirm the current requirements before starting work.
Key Takeaways
Duke Energy insulation rebates vary by state and utility territory. Florida and the Carolinas should not be treated as the same program.
In Florida, the attic insulation rebate is tied to Duke Energy Florida’s Home Energy Improvement program and requires a Home Energy Check before the project.
In North Carolina and South Carolina, insulation-related rebates may be available through Duke Energy’s Smart $aver / Insulate and Seal path, but homeowners should confirm the current amount and requirements for their specific Duke utility account.
Do not assume this rebate is available to all Duke Energy customers in Indiana, Ohio, or Kentucky unless Duke’s current location-specific rebate page confirms insulation eligibility.
Before hiring a contractor, confirm the audit requirement, contractor requirement, rebate amount, application deadline, and whether the rebate is applied instantly or submitted after installation.
What This Program Offers
Duke Energy offers insulation-related rebates through different residential energy-efficiency programs. The details depend heavily on the customer’s state, Duke Energy utility territory, home type, and project scope.
Duke Energy Florida attic insulation rebate
For Duke Energy Florida, the attic insulation rebate is part of the Home Energy Improvement program. The rebate is based on the home’s existing attic insulation level and whether the project brings the attic insulation to at least R-38.
| Florida Home Type | Existing Insulation Level | Required Final Level | Published Rebate Amount |
|---|---|---|---|
| Single-family home | R-19 or less | At least R-38 | $0.25 per square foot, up to $600 |
| Single-family home | R-12 or less | At least R-38 | $0.27 per square foot, up to $700 |
| Single-family home | R-2 or less | At least R-38 | $0.31 per square foot, up to $800 |
| Multifamily home | R-12 or less | At least R-38 | $0.27 per square foot, up to $300 |
| Multifamily home | R-2 or less | At least R-38 | $0.31 per square foot, up to $350 |
For Florida attic insulation, Duke Energy describes the rebate as an instant rebate when using an approved contractor. In plain language, that means eligible customers may see the rebate deducted from the contractor invoice rather than waiting for a separate reimbursement check.
Duke Energy Carolinas Smart $aver / Insulate and Seal rebate
In North Carolina and South Carolina, insulation-related rebates may be available through Duke Energy’s Smart $aver / Insulate and Seal program. This path is different from the Florida Home Energy Improvement program.
The Carolinas program may include attic insulation and air sealing, and current rebate listings commonly show an amount up to $700 for qualifying sealing and insulation work. However, homeowners should confirm the exact amount, service territory, home requirements, and contractor process directly with Duke Energy or a Smart $aver participating contractor before starting work.
Who May Qualify
Eligibility depends on which Duke Energy utility serves the home and which program path applies.
Florida
Florida homeowners may qualify if they are Duke Energy Florida residential customers, complete a Home Energy Check before the project, and complete qualifying attic insulation work through an approved or prequalified contractor.
For single-family homes, the strongest verified Florida rebate path is attic insulation that brings the home from a low existing insulation level to at least R-38. Multifamily homes may have a lower maximum rebate. Manufactured homes do not appear to qualify for the Florida attic insulation rebate based on Duke’s published prerequisite language, although they may qualify for other Duke Energy efficiency measures.
North Carolina and South Carolina
North Carolina and South Carolina homeowners may qualify if their home is served by Duke Energy Carolinas or Duke Energy Progress and the insulation project meets Smart $aver / Insulate and Seal requirements.
Because Duke Energy has more than one utility territory in the Carolinas, homeowners should confirm eligibility using their Duke Energy account or address. Living in North Carolina or South Carolina does not automatically mean the rebate applies.
Renters
Duke Energy’s home energy assessment programs may be available to some renters, but rebate eligibility can depend on the home type, account holder, landlord permission, and who pays for the project. Renters should confirm requirements with Duke Energy and the property owner before scheduling insulation work.
What Insulation Work May Qualify
The verified Florida rebate is focused on attic insulation, also described in program standards as a ceiling insulation upgrade. The work must bring qualifying attic insulation to the required final R-value.
In the Carolinas, the Smart $aver / Insulate and Seal path may include attic insulation and air sealing. Duct sealing may be available through a separate Smart $aver measure, but it should not be lumped together with attic insulation unless Duke’s current program rules show that it is part of the same approved scope.
This page should not claim that wall insulation, crawl space insulation, basement insulation, or spray foam work automatically qualifies for a Duke Energy rebate unless Duke Energy specifically confirms those measures for the customer’s location and project.

Items to confirm and why it mattes
Can This Be Combined With Other Incentives?
Duke Energy does not clearly publish one universal stacking rule for every insulation rebate path. Homeowners should confirm whether the Duke Energy rebate can be combined with state, local, contractor, or federal incentives before assuming multiple incentives can be used for the same project.
The federal Energy Efficient Home Improvement Credit may be relevant for some eligible past projects placed in service from 2023 through 2025. However, current IRS guidance says the credit is not available for property placed in service after December 31, 2025. Homeowners should consult a qualified tax professional for advice about their own tax situation.
Duke Energy still lists insulation-related rebate paths in Florida and the Carolinas, but availability depends on your utility territory and current program rules. Homeowners should verify the current program before starting work.
It depends on the program. In Florida, eligible single-family attic insulation may qualify for up to $800 if the home starts at R-2 or less and is brought to at least R-38.

For new 2026 projects, the federal Energy Efficient Home Improvement Credit should not be treated as active. IRS guidance says the credit is not allowed for property placed in service after December 31, 2025. Eligible past-year projects may be different, so homeowners should check IRS guidance and speak with a qualified tax professional.
