Is Duke Energy my energy provider?
In Altamonte Springs, almost certainly yes. The city created Altamonte Electric Utility on 3 October 2017, but it serves city-owned facilities only — streetlights, parks, the wastewater plant, the police department. The Florida Public Service Commission granted Duke Energy exclusive rights to serve residents and businesses here.
The city has a utility. It is not yours.
Altamonte Electric Utility, est. 2017This trips people up, and it is a genuinely local confusion rather than a generic one. Altamonte Springs really does run a municipal electric utility, created on 3 October 2017. It supplies city-owned facilities. It does not sell power to households, and the city reserved the right to self-generate only for its own operations.
The Florida Public Service Commission granted Duke Energy exclusive rights to serve residential and commercial customers in the Altamonte Springs area. So every residential HVAC rebate question in this city routes to Duke Energy Florida, not to city hall — even though the permit for the same job may well route to city hall.

Why it is worth being sure
Up to $1,000Because the rebate is real money and it has an order of operations. Duke Energy requires a free Home Energy Check completed within the previous 24 months before the equipment is installed. Replace the system first and apply afterwards and it is denied. There is no retroactive assessment.

| Electric strip heat → heat pump | $600 | 16.0 SEER & 9.0 HSPF, or 15.2 SEER2 & 7.5 HSPF2 |

Duke Energy publishes these amounts. The page they come from is not scoped to a single state — its body also references the Carolinas, Ohio, Kentucky and Indiana. The Florida application portal confirms the program and the Home Energy Check prerequisite apply to Duke Energy Florida, but no Florida-scoped statement of these specific dollar figures was located. Rebate amounts change. Every figure here is dated, and Duke Energy on 800.254.8535 is the only authority on what is payable today.
Duke's rebate line is 800.254.8535, application support is 877.364.9003, and the Florida portal is dukeenergyrebates.com/florida.
