Chicago / Harwood Heights
Harwood Heights has 8,821 residents (give or take 26) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1733435, checked 2026-10-19), about 10,692 people per square mile.

The quote form takes a ZIP code; for Harwood Heights that is 60706 (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 Harwood Heights is $81,086 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1733435, 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.
At 10,692 people per square mile, Harwood Heights is dense enough that noise setback rules and outdoor-unit placement on a small lot are the first questions the installer works through.
45% of Harwood Heights homes are single-family detached, 9% are in two- to four-unit buildings and 45% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1733435, checked 2026-10-19).
With 45% of Harwood Heights homes in buildings of five or more units and 45% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 41% of Harwood Heights homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1733435, checked 2026-10-19), the landlord signs the quote in many of them.
Harwood Heights has 5 points more detached houses than Cook County overall (40%) and 10 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).
41% of Harwood Heights homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1733435, 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.
Of the 3,637 occupied homes in Harwood Heights, 80% 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=160XX00US1733435, checked 2026-10-19).
Gas heats 80% of Harwood Heights 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.
Harwood Heights has about the Cook County oil share of 0% and 4 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).
No electric utility is on file for Harwood Heights 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 Harwood Heights address before counting it. With 12% of Harwood Heights homes already on electric heat and 83% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Harwood Heights has 3,753 housing units, 7% built before 1940 and 75% before 1980, with 11% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1733435, checked 2026-10-19).
Harwood Heights has 21 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 Harwood Heights home was built in 1968 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1733435, checked 2026-10-19) and the median home has 4.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1733435, checked 2026-10-19).
75% of Harwood Heights homes were built before 1980 and only 11% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1733435, 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.

That -3F figure is the Cook County cold-day number a Harwood Heights 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 80% of Harwood Heights 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 Harwood Heights home has 4.6 rooms and was built around 1968, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
