Columbus / Sunbury
Sunbury has 8,005 residents (give or take 42) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3975602, checked 2026-10-19), about 1,663 people per square mile.
Sunbury is about 19 miles from the Census center point for Columbus in a straight line and covers 4.814 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 2,894 occupied homes in Sunbury, 61% heat with natural gas, 0% with heating oil, 34% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3975602, checked 2026-10-19).
Gas heats 61% of Sunbury against electricity at 34%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
Sunbury has about the Delaware County oil share of 1% and 10 points more electric heat than the county's 24% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US39041, checked 2026-10-19).
Sunbury has 3,030 housing units, 8% built before 1940 and 27% before 1980, with 59% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3975602, checked 2026-10-19).
Sunbury has 9 points more homes built after 2000 than the county's 50% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US39041, checked 2026-10-19).
The median Sunbury home was built in 2005 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3975602, checked 2026-10-19) and the median home has 6.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3975602, checked 2026-10-19).
68% of Sunbury homes are single-family detached, 11% are in two- to four-unit buildings and 15% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3975602, checked 2026-10-19).
27% of Sunbury homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3975602, checked 2026-10-19), so beside the 68% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Sunbury has 6 points fewer detached houses than Delaware County overall (74%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US39041, checked 2026-10-19).
59% of Sunbury housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3975602, 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 Sunbury 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 Sunbury is $108,787 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3975602, 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 5F figure is the Delaware County cold-day number a Sunbury heat pump is sized against, so ask the installer to show the system's heating output at 5F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 61% of Sunbury on gas and 34% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Sunbury home has 6.3 rooms and was built around 2005, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
