Jacksonville / Jacksonville
Jacksonville is the city this door is named for; it covers 747.266 square miles of land (Census 2024 Gazetteer internal points and land area, https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/, checked 2026-10-19).
Jacksonville has 977,670 residents (give or take 41) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1235000, checked 2026-10-19), about 1,308 people per square mile.

Of the 394,370 occupied homes in Jacksonville, 3% heat with natural gas, 0% with heating oil, 94% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1235000, checked 2026-10-19).
Jacksonville has about the Duval County oil share of 0% and the same 94% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US12031, checked 2026-10-19).
Electricity already heats 94% of Jacksonville homes, ahead of gas at 3%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
The median Jacksonville home was built in 1987 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1235000, checked 2026-10-19) and the median home has 5.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1235000, checked 2026-10-19).
Jacksonville has 430,825 housing units, 5% built before 1940 and 40% before 1980, with 32% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1235000, checked 2026-10-19).
Jacksonville tracks Duval County on housing age, with the county at 5% pre-1940 and 32% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US12031, checked 2026-10-19).
59% of Jacksonville homes are single-family detached, 7% are in two- to four-unit buildings and 25% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1235000, checked 2026-10-19).
42% of Jacksonville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1235000, checked 2026-10-19), so beside the 59% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
42% of Jacksonville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1235000, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
No electric utility is on file for Jacksonville 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 Jacksonville address before counting it. With 94% of Jacksonville homes already on electric heat and 4% 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 Jacksonville is $69,872 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1235000, 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 Duval County cold-day number a Jacksonville 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 Jacksonville home has 5.5 rooms and was built around 1987, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
