Charlotte / Jacksonville
Jacksonville has 71,279 residents (give or take 48) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3734200, checked 2026-10-19), about 1,461 people per square mile.
Jacksonville is about 197 miles from the Census center point for Charlotte in a straight line and covers 48.802 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).
The quote form takes a ZIP code; for Jacksonville that is 28542, 28543 (Census 2020 ZCTA to county subdivision and ZCTA to place relationship files, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt and https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_place20_natl.txt, checked 2026-10-19).
49% of Jacksonville homes are single-family detached, 7% are in two- to four-unit buildings and 21% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3734200, checked 2026-10-19).
61% of Jacksonville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3734200, checked 2026-10-19), so beside the 49% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Of the 22,688 occupied homes in Jacksonville, 6% heat with natural gas, 0% with heating oil, 91% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3734200, checked 2026-10-19).
Electricity already heats 91% of Jacksonville homes, ahead of gas at 6%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Jacksonville has about the Onslow County oil share of 0% and 1 points less electric heat than the county's 92% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US37133, checked 2026-10-19).
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.
Jacksonville has 25,417 housing units, 1% built before 1940 and 37% before 1980, with 42% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3734200, checked 2026-10-19).
The median Jacksonville home was built in 1992 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3734200, checked 2026-10-19) and the median home has 5.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3734200, checked 2026-10-19).
Heating design temperature: 24F.

That 24F figure is the Onslow County cold-day number a Jacksonville heat pump is sized against, so ask the installer to show the system's heating output at 24F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Jacksonville home has 5.3 rooms and was built around 1992, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
