Cincinnati / Hamilton
Hamilton has 63,468 residents (give or take 91) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3933012, checked 2026-10-19), about 2,957 people per square mile.
Hamilton is about 18 miles from the Census center point for Cincinnati in a straight line and covers 21.465 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).
The quote form takes a ZIP code; for Hamilton that is 45015 (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 24,858 occupied homes in Hamilton, 61% heat with natural gas, 1% with heating oil, 35% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3933012, checked 2026-10-19).
Gas heats 61% of Hamilton against electricity at 35%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas boiler stays for the deepest cold, or a whole-home system when the house is ready for it.
Hamilton has about the Butler County oil share of 3% and 5 points less electric heat than the county's 40% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US39017, checked 2026-10-19).
Hamilton has 26,922 housing units, 27% built before 1940 and 78% before 1980, with 12% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3933012, checked 2026-10-19).
The median Hamilton home was built in 1956 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3933012, checked 2026-10-19) and the median home has 5.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3933012, checked 2026-10-19).
69% of Hamilton homes are single-family detached, 12% 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=160XX00US3933012, checked 2026-10-19).
46% of Hamilton homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3933012, 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.
No electric utility is on file for Hamilton on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Heating design temperature: 2F.

That 2F figure is the Butler County cold-day number a Hamilton heat pump is sized against, so ask the installer to show the system's heating output at 2F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 61% of Hamilton on gas and 35% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Hamilton home has 5.3 rooms and was built around 1956, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
