Portsmouth is about 88 miles from the Census center point for Cincinnati in a straight line and covers 10.729 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 7,334 occupied homes in Portsmouth, 68% heat with natural gas, 0% with heating oil, 28% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3964304, checked 2026-10-19).
Gas heats 68% of Portsmouth against electricity at 28%, 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.
Portsmouth has about the Scioto County oil share of 2% and 12 points less electric heat than the county's 40% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US39145, checked 2026-10-19).
Portsmouth has 8,466 housing units, 42% built before 1940 and 90% before 1980, with 3% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3964304, checked 2026-10-19).
The median Portsmouth home was built in 1946 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3964304, checked 2026-10-19) and the median home has 5.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3964304, checked 2026-10-19).
70% of Portsmouth homes are single-family detached, 9% are in two- to four-unit buildings and 20% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3964304, checked 2026-10-19).
With 70% detached houses and 9% in small multi-family buildings, a Portsmouth quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 52% of Portsmouth homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3964304, checked 2026-10-19), the landlord signs the quote in many of them.

Heating design temperature: 6F.

That 6F figure is the Scioto County cold-day number a Portsmouth heat pump is sized against, so ask the installer to show the system's heating output at 6F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 68% of Portsmouth on gas and 28% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Portsmouth house from before 1940 (42% of the 8,466 units) rarely matches a square-footage rule of thumb.
