The quote form takes a ZIP code; for Springfield that is 45501, 45503, 45504, 45505, 45506 (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 24,650 occupied homes in Springfield, 81% heat with natural gas, 0% with heating oil, 17% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3974118, checked 2026-10-19).
Gas heats 81% of Springfield against electricity at 17%, 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.
Springfield has 4 points less oil heat than Clark County as a whole, where 4% of homes burn oil, and 2 points less electric heat than the county's 19% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US39023, checked 2026-10-19).
Springfield has 27,758 housing units, 36% built before 1940 and 84% before 1980, with 7% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3974118, checked 2026-10-19).
The median Springfield home was built in 1953 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3974118, checked 2026-10-19) and the median home has 5.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3974118, checked 2026-10-19).
64% of Springfield homes are single-family detached, 9% are in two- to four-unit buildings and 17% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3974118, checked 2026-10-19).
48% of Springfield homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3974118, 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 Springfield on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Heating design temperature: 3F.

That 3F figure is the Clark County cold-day number a Springfield heat pump is sized against, so ask the installer to show the system's heating output at 3F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 81% of Springfield on gas and 17% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Springfield house from before 1940 (36% of the 27,758 units) rarely matches a square-footage rule of thumb.
