Chicago / Macomb
Macomb has 14,894 residents (give or take 25) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1745889, checked 2026-10-19), about 1,395 people per square mile.
Macomb is about 182 miles from the Census center point for Chicago in a straight line and covers 10.678 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 6,487 occupied homes in Macomb, 53% heat with natural gas, 0% with heating oil, 42% with electricity and 4% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1745889, checked 2026-10-19).
Gas heats 53% of Macomb against electricity at 42%, 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.
Macomb has about the McDonough County oil share of 0% and 10 points more electric heat than the county's 32% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US17109, checked 2026-10-19).
Macomb has 7,464 housing units, 24% built before 1940 and 69% before 1980, with 17% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1745889, checked 2026-10-19).
Macomb has 3 points fewer pre-1940 homes than McDonough County as a whole (27%) and 3 points more homes built after 2000 than the county's 14% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US17109, checked 2026-10-19).
The median Macomb home was built in 1967 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1745889, checked 2026-10-19) and the median home has 4.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1745889, checked 2026-10-19).
53% of Macomb homes are single-family detached, 10% are in two- to four-unit buildings and 29% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1745889, checked 2026-10-19).
51% of Macomb homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1745889, checked 2026-10-19), so beside the 53% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Macomb has 14 points fewer detached houses than McDonough County overall (67%) and 12 points more five-plus-unit buildings than the county's 17% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US17109, checked 2026-10-19).
51% of Macomb homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1745889, 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.
69% of Macomb homes were built before 1980 and only 17% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1745889, 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 Macomb 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 Macomb address before counting it. With 42% of Macomb homes already on electric heat and 57% 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 Macomb is $44,411 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1745889, 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 -2F figure is the McDonough County cold-day number a Macomb heat pump is sized against, so ask the installer to show the system's heating output at -2F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 53% of Macomb on gas and 42% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Macomb home has 4.9 rooms and was built around 1967, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
