Raleigh / Siler City
Siler City has 7,995 residents (give or take 18) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3761860, checked 2026-10-19), about 1,185 people per square mile.
Siler City is about 47 miles from the Census center point for Raleigh in a straight line and covers 6.745 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 3,027 occupied homes in Siler City, 27% heat with natural gas, 4% with heating oil, 68% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3761860, checked 2026-10-19).
Electricity already heats 68% of Siler City homes, ahead of gas at 27%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Siler City has 3 points more oil heat than Chatham County as a whole, where 1% of homes burn oil, and 18 points more electric heat than the county's 50% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US37037, checked 2026-10-19).
Siler City has 3,309 housing units, 9% built before 1940 and 50% before 1980, with 24% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3761860, checked 2026-10-19).
Siler City has 5 points more pre-1940 homes than Chatham County as a whole (4%) and 21 points fewer homes built after 2000 than the county's 45% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US37037, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Siler City home was built in 1980 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3761860, checked 2026-10-19) and the median home has 5.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3761860, checked 2026-10-19).
55% of Siler City homes are single-family detached, 10% are in two- to four-unit buildings and 13% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3761860, checked 2026-10-19).
44% of Siler City homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3761860, checked 2026-10-19), so beside the 55% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Siler City has 22 points fewer detached houses than Chatham County overall (77%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US37037, checked 2026-10-19).
44% of Siler City homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3761860, 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 Siler City 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 Siler City is $46,566 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3761860, 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.

That 20F figure is the Chatham County cold-day number a Siler City heat pump is sized against, so ask the installer to show the system's heating output at 20F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Siler City home has 5.1 rooms and was built around 1980, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
