Chicago / Evergreen Park
Evergreen Park is about 8 miles from the Census center point for Chicago in a straight line and covers 3.163 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).
Evergreen Park has 19,420 residents (give or take 34) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1724634, checked 2026-10-19), about 6,140 people per square mile.
The quote form takes a ZIP code; for Evergreen Park that is 60805 (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).
6,140 people per square mile puts Evergreen Park in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 7,215 occupied homes in Evergreen Park, 90% heat with natural gas, 0% with heating oil, 8% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1724634, checked 2026-10-19).
Evergreen Park has about the Cook County oil share of 0% and 8 points less 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).
Gas heats 90% of Evergreen Park against electricity at 8%, 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.
The median Evergreen Park home was built in 1955 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1724634, checked 2026-10-19) and the median home has 6.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1724634, checked 2026-10-19).
Evergreen Park has 7,538 housing units, 12% built before 1940 and 92% before 1980, with 5% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1724634, checked 2026-10-19).
Evergreen Park has 16 points fewer pre-1940 homes than Cook County as a whole (28%) and 8 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=050XX00US17031, checked 2026-10-19).
92% of Evergreen Park homes were built before 1980 and only 5% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1724634, 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.
87% of Evergreen Park homes are single-family detached, 2% 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=160XX00US1724634, checked 2026-10-19).
With 87% detached houses and 2% in small multi-family buildings, a Evergreen Park quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 15% of Evergreen Park homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1724634, checked 2026-10-19), the landlord signs the quote in many of them.
Evergreen Park has 47 points more detached houses than Cook County overall (40%) and 25 points fewer 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).
Only 15% of Evergreen Park homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1724634, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.
No electric utility is on file for Evergreen Park 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 Evergreen Park address before counting it. With 8% of Evergreen Park homes already on electric heat and 91% 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 Evergreen Park is $95,719 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1724634, 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: -3F.

That -3F figure is the Cook County cold-day number a Evergreen Park 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 90% of Evergreen Park on gas and 8% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Evergreen Park home has 6.2 rooms and was built around 1955, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
