Des Moines / Ankeny
Ankeny is about 11 miles from the Census center point for Des Moines in a straight line and covers 31.905 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).
Ankeny has 72,615 residents (give or take 64) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1902305, checked 2026-10-19), about 2,276 people per square mile.
The quote form takes a ZIP code; for Ankeny that is 50021, 50023 (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 28,361 occupied homes in Ankeny, 66% heat with natural gas, 0% with heating oil, 33% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1902305, checked 2026-10-19).
Ankeny has about the Polk County oil share of 0% and 2 points more electric heat than the county's 31% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US19153, checked 2026-10-19).
Gas heats 66% of Ankeny against electricity at 33%, 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 Ankeny home was built in 2006 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1902305, checked 2026-10-19) and the median home has 6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1902305, checked 2026-10-19).
Ankeny has 29,781 housing units, 1% built before 1940 and 19% before 1980, with 63% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1902305, checked 2026-10-19).
Ankeny has 13 points fewer pre-1940 homes than Polk County as a whole (14%) and 33 points more homes built after 2000 than the county's 30% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US19153, checked 2026-10-19).
63% of Ankeny housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1902305, checked 2026-10-19), and homes that recent usually meet the insulation codes in place at the time, so a heat pump sized to the floor plan lands closer to the real load than it would in an older neighborhood.
58% of Ankeny homes are single-family detached, 3% are in two- to four-unit buildings and 22% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1902305, checked 2026-10-19).
29% of Ankeny homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1902305, checked 2026-10-19), so beside the 58% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Ankeny has 5 points fewer detached houses than Polk County overall (63%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US19153, checked 2026-10-19).
MidAmerican Energy lists Ankeny among the Iowa communities it serves for electricity (MidAmerican Energy community list, electric communities, https://www.midamericanenergy.com/territory-communitylist, checked 2026-10-19).
MidAmerican 2026 Instant Discount air source heat pump, run by MidAmerican Energy, is a live program for Iowa addresses and covers qualifying equipment at $1,200 per system (registry row 31 verified 2026-10-14, https://www.midamericanenergy.com/home-discounts-and-rebates, checked 2026-10-16); confirm eligibility for the Ankeny address before counting it. With 33% of Ankeny homes already on electric heat and 66% 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 Ankeny is $108,198 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1902305, 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.

That -5F figure is the Polk County cold-day number a Ankeny heat pump is sized against, so ask the installer to show the system's heating output at -5F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 66% of Ankeny on gas and 33% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Ankeny home has 6 rooms and was built around 2006, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
