Cincinnati / Cambridge
Cambridge has 10,060 residents (give or take 31) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3910996, checked 2026-10-19), about 1,580 people per square mile.
Cambridge is about 167 miles from the Census center point for Cincinnati in a straight line and covers 6.367 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 5,017 occupied homes in Cambridge, 72% heat with natural gas, 0% with heating oil, 26% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3910996, checked 2026-10-19).
Gas heats 72% of Cambridge against electricity at 26%, 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.
Cambridge has 4 points less oil heat than Guernsey County as a whole, where 4% of homes burn oil, and 2 points less electric heat than the county's 28% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US39059, checked 2026-10-19).
Cambridge has 5,420 housing units, 32% built before 1940 and 78% before 1980, with 8% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3910996, checked 2026-10-19).
The median Cambridge home was built in 1955 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3910996, checked 2026-10-19) and the median home has 5.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3910996, checked 2026-10-19).
64% of Cambridge homes are single-family detached, 13% are in two- to four-unit buildings and 18% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3910996, checked 2026-10-19).
51% of Cambridge homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3910996, 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.
No electric utility is on file for Cambridge on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Heating design temperature: 7F.

That 7F figure is the Guernsey County cold-day number a Cambridge heat pump is sized against, so ask the installer to show the system's heating output at 7F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 72% of Cambridge on gas and 26% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Cambridge house from before 1940 (32% of the 5,420 units) rarely matches a square-footage rule of thumb.
