Cincinnati / Cincinnati
Cincinnati has 311,224 residents (give or take 60) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3915000, checked 2026-10-19), about 3,994 people per square mile.
Cincinnati is the city this door is named for; it covers 77.914 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 Cincinnati that is 45202, 45203, 45204, 45205, 45206, 45207, 45208, 45209 and 18 more (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).
Median household income in Cincinnati is $52,909 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3915000, 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.
3,994 people per square mile puts Cincinnati in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
38% of Cincinnati homes are single-family detached, 20% are in two- to four-unit buildings and 36% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3915000, checked 2026-10-19).
60% of Cincinnati homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3915000, checked 2026-10-19), so beside the 38% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Cincinnati has 20 points fewer detached houses than Hamilton County overall (58%) and 12 points more five-plus-unit buildings than the county's 24% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US39061, checked 2026-10-19).
With 60% of Cincinnati homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3915000, checked 2026-10-19), most heat pump quotes here are landlord-driven: the landlord signs the contract and picks the equipment, and the tenant sees the lower bill.
Of the 144,297 occupied homes in Cincinnati, 56% heat with natural gas, 0% with heating oil, 39% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3915000, checked 2026-10-19).
Gas heats 56% of Cincinnati against electricity at 39%, 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.
Cincinnati has about the Hamilton County oil share of 1% and 4 points more electric heat than the county's 35% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US39061, checked 2026-10-19).
No electric utility is on file for Cincinnati on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Cincinnati has 160,409 housing units, 41% built before 1940 and 80% before 1980, with 10% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3915000, checked 2026-10-19).
Cincinnati has 16 points more pre-1940 homes than Hamilton County as a whole (25%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US39061, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Cincinnati home was built in 1951 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3915000, checked 2026-10-19) and the median home has 4.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3915000, checked 2026-10-19).
41% of Cincinnati homes were built before 1940 and 80% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3915000, checked 2026-10-19), so insulation is the first sizing question: an older home leaks more heat per square foot, and the installer runs a room-by-room heat-loss calculation to size the system for what the walls and windows actually hold in, not just the floor plan.
Heating design temperature: 5F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Hamilton County row, 99% heating, PDF pages 94 to 97 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That 5F figure is the Hamilton County cold-day number a Cincinnati 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 56% of Cincinnati on gas and 39% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Cincinnati house from before 1940 (41% of the 160,409 units) rarely matches a square-footage rule of thumb.
