Cincinnati / Lima
Lima has 35,010 residents (give or take 46) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3943554, checked 2026-10-19), about 2,571 people per square mile.
Lima is about 113 miles from the Census center point for Cincinnati in a straight line and covers 13.619 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 Lima that is 45804, 45805 (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 14,273 occupied homes in Lima, 71% heat with natural gas, 0% with heating oil, 27% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3943554, checked 2026-10-19).
Gas heats 71% of Lima against electricity at 27%, 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.
Lima has about the Allen County oil share of 1% and 3 points more electric heat than the county's 24% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US39003, checked 2026-10-19).
Lima has 15,950 housing units, 31% built before 1940 and 83% before 1980, with 7% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3943554, checked 2026-10-19).
The median Lima home was built in 1955 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3943554, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3943554, checked 2026-10-19).
71% of Lima homes are single-family detached, 11% 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=160XX00US3943554, checked 2026-10-19).
With 71% detached houses and 11% in small multi-family buildings, a Lima quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 54% of Lima homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3943554, checked 2026-10-19), the landlord signs the quote in many of them.
No electric utility is on file for Lima on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Heating design temperature: 4F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Allen 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 4F figure is the Allen County cold-day number a Lima heat pump is sized against, so ask the installer to show the system's heating output at 4F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 71% of Lima on gas and 27% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Lima house from before 1940 (31% of the 15,950 units) rarely matches a square-footage rule of thumb.
