El Dorado has 12,769 residents (give or take 49) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US2020075, checked 2026-10-19), about 1,335 people per square mile.
El Dorado is about 28 miles from the Census center point for Wichita in a straight line and covers 9.563 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 5,436 occupied homes in El Dorado, 69% heat with natural gas, 0% with heating oil, 24% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2020075, checked 2026-10-19).
Gas heats 69% of El Dorado against electricity at 24%, 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.
El Dorado has about the Butler County oil share of 0% and 5 points less electric heat than the county's 29% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US20015, checked 2026-10-19).
El Dorado has 6,209 housing units, 23% built before 1940 and 72% before 1980, with 10% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2020075, checked 2026-10-19).
The median El Dorado home was built in 1959 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2020075, checked 2026-10-19) and the median home has 5.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2020075, checked 2026-10-19).
76% of El Dorado homes are single-family detached, 9% are in two- to four-unit buildings and 10% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2020075, checked 2026-10-19).
With 76% detached houses and 9% in small multi-family buildings, a El Dorado quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 40% of El Dorado homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2020075, checked 2026-10-19), the landlord signs the quote in many of them.

Heating design temperature: 7F.

That 7F figure is the Butler County cold-day number a El Dorado 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 69% of El Dorado on gas and 24% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median El Dorado home has 5.9 rooms and was built around 1959, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
