The quote form takes a ZIP code; for Hardeeville that is 29927 (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).
Hardeeville is spread out at 181 people per square mile across 60.066 square miles of land, so a long refrigerant line run between the outdoor unit and the farthest indoor head is the sizing question an installer checks first.
Of the 5,238 occupied homes in Hardeeville, 47% heat with natural gas, 0% with heating oil, 53% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4532245, checked 2026-10-19).
Electricity already heats 53% of Hardeeville homes, ahead of gas at 47%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Hardeeville has about the Jasper County oil share of 0% and 22 points less electric heat than the county's 75% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US45053, checked 2026-10-19).
Hardeeville has 5,740 housing units, 3% built before 1940 and 7% before 1980, with 85% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4532245, checked 2026-10-19).
Hardeeville has 28 points more homes built after 2000 than the county's 57% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US45053, checked 2026-10-19).
The median Hardeeville home was built in 2014 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4532245, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4532245, checked 2026-10-19).
61% of Hardeeville homes are single-family detached, 4% are in two- to four-unit buildings and 19% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4532245, checked 2026-10-19).
23% of Hardeeville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4532245, checked 2026-10-19), so beside the 61% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Hardeeville has 6 points more detached houses than Jasper County overall (55%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US45053, checked 2026-10-19).
85% of Hardeeville housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4532245, checked 2026-10-19), and homes that recent usually meet the insulation codes in place at the time, so a heat pump sized to the floor plan lands closer to the real load than it would in an older neighborhood.
No electric utility is on file for Hardeeville on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in Hardeeville is $78,365 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4532245, 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: 29F.

That 29F figure is the Jasper County cold-day number a Hardeeville heat pump is sized against, so ask the installer to show the system's heating output at 29F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Hardeeville home has 5.6 rooms and was built around 2014, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
