Replacement Windows in North Carolina

Current incentive status, energy-code requirements, and local market research for North Carolina homeowners replacing windows and doors.

Rebates & incentives

The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.

North Carolina's Energy Saver NC program (run by the DEQ State Energy Office) launched in January 2025 and became available in all 100 counties by early 2026, offering both HEAR and Home Efficiency (HOMES) rebates. Windows fit under the whole-home efficiency track, where rebates scale with income and projected energy savings. Confirm current availability first.

  • Duke Energy Smart $aver window rebates. Duke Energy offers one of the few dedicated window replacement rebates in the country for Carolinas customers — but with real strings: the home must have electric heating (heat pump, electric furnace, or radiant electric), work must be done by a participating contractor, only complete replacements with air sealing qualify, and gas-heated homes, north-facing windows, and patio doors are excluded. Confirm current amounts and terms. (Duke-Energy.com Smart $aver windows page)
  • Duke Energy Home Energy House Call. A free in-home energy assessment for Duke customers that documents where a home loses energy — a practical first step for homeowners weighing window replacement against other efficiency upgrades. (Duke-Energy.com residential program pages)

Energy code

North Carolina's legislature froze residential energy code updates in 2023, leaving standards roughly equivalent to the 2009 IECC in place into the 2030s — so code minimums for replacement windows are comparatively lax, and efficient windows are a homeowner choice rather than a permitting requirement.
