No electric utility is on file for Green Cove Springs on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Florida utility heat pump rebates (Orlando, Tampa), run by OUC / Duke Energy Florida / TECO, is a live program for Florida addresses and covers qualifying equipment at $1,150 per system (registry row 26 verified 2026-10-15, https://www.ouc.com/solutions-programs/savings/rebates/heat-pump-ac/, checked 2026-10-16); confirm eligibility for the Green Cove Springs address before counting it. With 98% of Green Cove Springs homes already on electric heat and 1% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in Green Cove Springs is $75,142 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1227400, checked 2026-10-19); many state and utility heat pump rebate programs set higher incentive tiers for income-qualifying households, so the household income on the application, not the town median, decides which level applies.
Heating design temperature: 32F.

That 32F figure is the Clay County cold-day number a Green Cove Springs heat pump is sized against, so ask the installer to show the system's heating output at 32F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Green Cove Springs home has 6.1 rooms and was built around 1998, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
