The quote form takes a ZIP code; for Creve Coeur that is 63141 (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 8,158 occupied homes in Creve Coeur, 55% heat with natural gas, 0% with heating oil, 44% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2917272, checked 2026-10-19).
Gas heats 55% of Creve Coeur against electricity at 44%, 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.
Creve Coeur has about the St. Louis County oil share of 0% and 21 points more electric heat than the county's 23% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US29189, checked 2026-10-19).
Creve Coeur has 8,821 housing units, 1% built before 1940 and 51% before 1980, with 22% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2917272, checked 2026-10-19).
Creve Coeur has 9 points fewer pre-1940 homes than St. Louis County as a whole (10%) and 11 points more homes built after 2000 than the county's 11% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US29189, checked 2026-10-19).
The median Creve Coeur home was built in 1980 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2917272, checked 2026-10-19) and the median home has 6.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2917272, checked 2026-10-19).
51% of Creve Coeur homes are single-family detached, 4% are in two- to four-unit buildings and 39% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2917272, checked 2026-10-19).
39% of Creve Coeur homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2917272, checked 2026-10-19), so beside the 51% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Creve Coeur has 21 points fewer detached houses than St. Louis County overall (72%) and 22 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=050XX00US29189, checked 2026-10-19).
No electric utility is on file for Creve Coeur on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in Creve Coeur is $127,188 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2917272, 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 St. Louis County cold-day number a Creve Coeur 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 55% of Creve Coeur on gas and 44% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Creve Coeur home has 6.3 rooms and was built around 1980, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
