Columbus / Dublin
Dublin is about 12 miles from the Census center point for Columbus in a straight line and covers 24.682 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).
Dublin has 49,294 residents (give or take 83) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3922694, checked 2026-10-19), about 1,997 people per square mile.
The quote form takes a ZIP code; for Dublin that is 43016, 43017 (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).
Of the 17,995 occupied homes in Dublin, 77% heat with natural gas, 0% with heating oil, 21% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3922694, checked 2026-10-19).
Dublin has about the Franklin County oil share of 0% and 10 points less electric heat than the county's 31% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US39049, checked 2026-10-19).
Gas heats 77% of Dublin against electricity at 21%, 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.
The median Dublin home was built in 1996 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3922694, checked 2026-10-19) and the median home has 7.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3922694, checked 2026-10-19).
Dublin has 18,639 housing units, 1% built before 1940 and 11% before 1980, with 39% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3922694, checked 2026-10-19).
Dublin has 10 points fewer pre-1940 homes than Franklin County as a whole (11%) and 16 points more homes built after 2000 than the county's 23% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US39049, checked 2026-10-19).
69% of Dublin homes are single-family detached, 4% are in two- to four-unit buildings and 14% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3922694, checked 2026-10-19).
23% of Dublin homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3922694, checked 2026-10-19), so beside the 69% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Dublin has 17 points more detached houses than Franklin County overall (52%) and 12 points fewer five-plus-unit buildings than the county's 26% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US39049, checked 2026-10-19).
No electric utility is on file for Dublin 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 Dublin is $160,296 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3922694, 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: 5F.

That 5F figure is the Franklin County cold-day number a Dublin 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 77% of Dublin on gas and 21% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Dublin home has 7.8 rooms and was built around 1996, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
