Charleston / Lexington
Lexington has 24,585 residents (give or take 36) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4541335, checked 2026-10-19), about 2,054 people per square mile.
Lexington is about 108 miles from the Census center point for Charleston in a straight line and covers 11.97 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 9,778 occupied homes in Lexington, 35% heat with natural gas, 0% with heating oil, 63% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4541335, checked 2026-10-19).
Electricity already heats 63% of Lexington homes, ahead of gas at 35%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Lexington has about the Lexington County oil share of 0% and 6 points less electric heat than the county's 69% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US45063, checked 2026-10-19).
Lexington has 10,348 housing units, 1% built before 1940 and 9% before 1980, with 57% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4541335, checked 2026-10-19).
Lexington has 19 points more homes built after 2000 than the county's 38% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US45063, checked 2026-10-19).
The median Lexington home was built in 2002 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4541335, checked 2026-10-19) and the median home has 5.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4541335, checked 2026-10-19).
64% of Lexington homes are single-family detached, 3% are in two- to four-unit buildings and 24% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4541335, checked 2026-10-19).
31% of Lexington homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4541335, checked 2026-10-19), so beside the 64% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Lexington has 6 points fewer detached houses than Lexington County overall (70%) and 17 points more five-plus-unit buildings than the county's 7% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US45063, checked 2026-10-19).
57% of Lexington housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4541335, 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 Lexington 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 Lexington is $87,126 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4541335, 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: 24F.

That 24F figure is the Lexington County cold-day number a Lexington 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 Lexington home has 5.9 rooms and was built around 2002, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
