Chicago / Rantoul
Rantoul has 12,421 residents (give or take 284) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1762783, checked 2026-10-19), about 1,463 people per square mile.
Rantoul is about 109 miles from the Census center point for Chicago in a straight line and covers 8.49 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 5,374 occupied homes in Rantoul, 71% heat with natural gas, 0% with heating oil, 28% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1762783, checked 2026-10-19).
Gas heats 71% of Rantoul against electricity at 28%, 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.
Rantoul has about the Champaign County oil share of 0% and 13 points less electric heat than the county's 41% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US17019, checked 2026-10-19).
Rantoul has 6,089 housing units, 9% built before 1940 and 76% before 1980, with 12% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1762783, checked 2026-10-19).
Rantoul has 3 points fewer pre-1940 homes than Champaign County as a whole (12%) and 17 points fewer homes built after 2000 than the county's 29% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US17019, checked 2026-10-19).
The median Rantoul home was built in 1966 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1762783, checked 2026-10-19) and the median home has 5.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1762783, checked 2026-10-19).
55% of Rantoul homes are single-family detached, 13% are in two- to four-unit buildings and 19% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1762783, checked 2026-10-19).
45% of Rantoul homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1762783, checked 2026-10-19), so beside the 55% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Rantoul has 14 points fewer five-plus-unit buildings than the county's 33% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US17019, checked 2026-10-19).
45% of Rantoul homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1762783, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
76% of Rantoul homes were built before 1980 and only 12% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1762783, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
No electric utility is on file for Rantoul on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Ameren Illinois Instant Incentives (ducted ASHP), run by Ameren Illinois, is a live program for Illinois addresses and lists a standard figure of $900 (registry row 45 verified 2026-10-15, https://amerenillinoissavings.com/residential/ducted-air-source-heat-pump/, checked 2026-10-16); confirm eligibility for the Rantoul address before counting it. With 28% of Rantoul homes already on electric heat and 71% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in Rantoul is $48,691 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1762783, 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.

That 1F figure is the Champaign County cold-day number a Rantoul heat pump is sized against, so ask the installer to show the system's heating output at 1F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 71% of Rantoul 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; the median Rantoul home has 5.3 rooms and was built around 1966, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
