Des Moines / Hiawatha
Hiawatha has 7,206 residents (give or take 37) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1935940, checked 2026-10-19), about 1,512 people per square mile.
Hiawatha is about 104 miles from the Census center point for Des Moines in a straight line and covers 4.765 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 Hiawatha that is 52233 (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 Hiawatha is $66,270 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1935940, 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.
48% of Hiawatha homes are single-family detached, 8% are in two- to four-unit buildings and 23% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1935940, checked 2026-10-19).
33% of Hiawatha homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1935940, checked 2026-10-19), so beside the 48% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Hiawatha has 19 points fewer detached houses than Linn County overall (67%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US19113, checked 2026-10-19).
Of the 2,936 occupied homes in Hiawatha, 74% heat with natural gas, 0% with heating oil, 20% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1935940, checked 2026-10-19).
Gas heats 74% of Hiawatha against electricity at 20%, 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.
Hiawatha has about the Linn County oil share of 0% and 1 points more electric heat than the county's 19% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US19113, checked 2026-10-19).
No electric utility is on file for Hiawatha on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
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 Hiawatha address before counting it. With 20% of Hiawatha homes already on electric heat and 77% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Hiawatha has 3,183 housing units, 6% built before 1940 and 37% before 1980, with 32% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1935940, checked 2026-10-19).
Hiawatha has 8 points fewer pre-1940 homes than Linn County as a whole (14%) and 5 points more homes built after 2000 than the county's 27% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US19113, checked 2026-10-19).
The median Hiawatha home was built in 1992 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1935940, checked 2026-10-19) and the median home has 5.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1935940, checked 2026-10-19).

That -6F figure is the Linn County cold-day number a Hiawatha heat pump is sized against, so ask the installer to show the system's heating output at -6F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 74% of Hiawatha on gas and 20% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Hiawatha home has 5.9 rooms and was built around 1992, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
