Chicago / Crestwood
Crestwood has 10,579 residents (give or take 31) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1717497, checked 2026-10-19), about 3,470 people per square mile.
Crestwood is about 14 miles from the Census center point for Chicago in a straight line and covers 3.049 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 Crestwood that is 60418 (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).
Median household income in Crestwood is $75,752 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1717497, 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.
3,470 people per square mile puts Crestwood in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
41% of Crestwood homes are single-family detached, 1% are in two- to four-unit buildings and 56% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1717497, checked 2026-10-19).
With 56% of Crestwood homes in buildings of five or more units and 41% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 24% of Crestwood homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1717497, checked 2026-10-19), the landlord signs the quote in many of them.
Crestwood has 21 points more five-plus-unit buildings than the county's 35% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US17031, checked 2026-10-19).
Of the 4,902 occupied homes in Crestwood, 77% heat with natural gas, 0% with heating oil, 19% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1717497, checked 2026-10-19).
Gas heats 77% of Crestwood against electricity at 19%, 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.
Crestwood has about the Cook County oil share of 0% and 3 points more electric heat than the county's 16% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US17031, checked 2026-10-19).
No electric utility is on file for Crestwood 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 Crestwood address before counting it. With 19% of Crestwood homes already on electric heat and 79% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Crestwood has 5,145 housing units, 2% built before 1940 and 61% before 1980, with 14% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1717497, checked 2026-10-19).
Crestwood has 26 points fewer pre-1940 homes than Cook County as a whole (28%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US17031, checked 2026-10-19).
The median Crestwood home was built in 1976 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1717497, checked 2026-10-19) and the median home has 5.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1717497, checked 2026-10-19).
61% of Crestwood homes were built before 1980 and only 14% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1717497, 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.
Heating design temperature: -3F.

That -3F figure is the Cook County cold-day number a Crestwood 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 77% of Crestwood on gas and 19% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Crestwood home has 5.1 rooms and was built around 1976, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
