Chicago / Peru
Peru has 9,775 residents (give or take 207) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1759234, checked 2026-10-19), about 948 people per square mile.
Peru is about 82 miles from the Census center point for Chicago in a straight line and covers 10.316 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).
The quote form takes a ZIP code; for Peru that is 61354 (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 4,480 occupied homes in Peru, 84% heat with natural gas, 0% with heating oil, 12% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1759234, checked 2026-10-19).
Gas heats 84% of Peru against electricity at 12%, 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.
Peru has about the LaSalle County oil share of 0% and 2 points less electric heat than the county's 14% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US17099, checked 2026-10-19).
Peru has 4,853 housing units, 28% built before 1940 and 80% before 1980, with 7% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1759234, checked 2026-10-19).
Peru has 3 points more pre-1940 homes than LaSalle County as a whole (25%) and 6 points fewer homes built after 2000 than the county's 13% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US17099, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Peru home was built in 1958 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1759234, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1759234, checked 2026-10-19).
85% of Peru homes are single-family detached, 5% are in two- to four-unit buildings and 7% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1759234, checked 2026-10-19).
With 85% detached houses and 5% in small multi-family buildings, a Peru quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 25% of Peru homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1759234, checked 2026-10-19), the landlord signs the quote in many of them.
Peru has 6 points more detached houses than LaSalle County overall (79%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US17099, checked 2026-10-19).
80% of Peru homes were built before 1980 and only 7% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1759234, 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 Peru 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 Peru address before counting it. With 12% of Peru homes already on electric heat and 87% 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 Peru is $74,808 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1759234, 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.
Heating design temperature: -2F.

That -2F figure is the LaSalle County cold-day number a Peru 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 84% of Peru on gas and 12% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Peru home has 5.6 rooms and was built around 1958, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
