Charleston / York
York has 8,969 residents (give or take 35) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4579630, checked 2026-10-19), about 1,057 people per square mile.
York is about 166 miles from the Census center point for Charleston in a straight line and covers 8.487 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).
Of the 3,418 occupied homes in York, 28% heat with natural gas, 0% with heating oil, 69% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4579630, checked 2026-10-19).
Electricity already heats 69% of York homes, ahead of gas at 28%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
York has about the York County oil share of 1% and 19 points more electric heat than the county's 50% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US45091, checked 2026-10-19).
York has 3,917 housing units, 7% built before 1940 and 46% before 1980, with 26% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4579630, checked 2026-10-19).
York has 4 points more pre-1940 homes than York County as a whole (3%) and 24 points fewer homes built after 2000 than the county's 50% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US45091, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median York home was built in 1984 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4579630, checked 2026-10-19) and the median home has 5.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4579630, checked 2026-10-19).
74% of York homes are single-family detached, 6% are in two- to four-unit buildings and 4% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4579630, checked 2026-10-19).
With 74% detached houses and 6% in small multi-family buildings, a York quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 33% of York homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4579630, checked 2026-10-19), the landlord signs the quote in many of them.
York has 5 points more detached houses than York County overall (69%) and 10 points fewer five-plus-unit buildings than the county's 14% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US45091, checked 2026-10-19).
No electric utility is on file for York 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 York is $56,176 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4579630, 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: 22F.

That 22F figure is the York County cold-day number a York heat pump is sized against, so ask the installer to show the system's heating output at 22F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median York home has 5.2 rooms and was built around 1984, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
