Duke Energy Smart $aver Rebates: How They Work

For most Triangle homeowners, the main utility rebate program for efficiency upgrades is Duke Energy's Smart $aver. It's straightforward once you understand one rule: the rebate runs through the contractor, not through you. Here's how it works as of October 2026.

Who's eligible

You need to be a Duke Energy electric customer. That's most of Wake, Durham, Orange and Johnston counties, but not everyone. Several towns run their own electric utilities, including Wake Forest (Wake Forest Power), Apex and Clayton. If your power bill comes from your town, Smart $aver rebates don't apply; ask your town about its programs instead. Apex, for example, runs a load management program with bill credits and its own heat pump rebate.

What's on the list

Duke's Smart $aver page lists rebates for:

• HVAC: qualifying heat pumps and air conditioners;
• heat pump water heaters;
• insulation;
• air sealing;
• pool pumps.

Windows, doors, roofing and siding aren't on the list. Amounts and efficiency requirements change; check Duke's page for current terms rather than relying on a contractor's memory.

How the process works

Duke lays it out in three steps:

1. Find a participating contractor. Use Duke's contractor finder to connect with its network of participating contractors. Only Smart $aver participating contractors are approved to perform work that qualifies for a rebate.
2. Have the work done.
3. The contractor files. After the work is complete, the contractor completes and submits the rebate application and documentation for you. You choose a physical card in the mail or a digital Mastercard for your virtual wallet.

Duke says the process typically takes four to six weeks after it receives the application.

Planning an upgrade around the rebate

The rebate should shape the order of work, not the size of the system. A sensible sequence for a typical Triangle house built in the 1980s or 1990s:

• Start with an assessment. Ask a participating insulation or HVAC contractor to look at the attic, the crawl space and the ducts. Many comfort complaints, such as hot bonus rooms, cold floors and high summer humidity, come from air leaks and duct problems rather than equipment.
• Seal and insulate next. Air sealing the attic floor and adding insulation lowers the load on whatever system you buy.
• Then size the new equipment. With a tighter house, a properly sized heat pump may be smaller than the one you have, which costs less up front and controls humidity better.
• Consider the water heater. If your electric tank is near the end of its life, a heat pump water heater is on Duke's list too.

Doing the envelope work first also means the HVAC contractor's load calculation reflects the house you'll actually have.

Contractor credentials

Duke says contractors in its Find It Duke network are industry-licensed professionals, and that contractors participating in its insulation and sealing programs are certified by the Building Performance Institute (BPI) or North American Technician Excellence (NATE). For HVAC, still verify the North Carolina heating license yourself at nclicensing.org; the rebate network isn't a substitute for checking.

Getting the most from it

• Ask before you sign. Confirm that the contractor is a participating Smart $aver contractor and that the specific model qualifies.
• Get the rebate in writing on the contract, with a note that it's subject to Duke's approval.
• Bundle the envelope work. Air sealing and insulation done together often improve comfort more than a bigger HVAC system would, and both are on the list.
• Keep copies of the application and the contractor's invoice until the payment arrives.
• Follow up if you haven't heard anything after six weeks. Duke has a feedback form for program questions.

Combining with other programs

• Federal tax credits for these upgrades ended for property placed in service after December 31, 2025. See our guide.
• Energy Saver North Carolina serves income-eligible households and has its own rules about combining incentives; ask before you assume you can stack them.
