Des Moines / Clinton
Clinton has 24,322 residents (give or take 18) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1914430, checked 2026-10-19), about 683 people per square mile.
Clinton is about 175 miles from the Census center point for Des Moines in a straight line and covers 35.6 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 Clinton that is 52732 (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 10,754 occupied homes in Clinton, 77% heat with natural gas, 0% with heating oil, 17% with electricity and 4% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1914430, checked 2026-10-19).
Gas heats 77% of Clinton against electricity at 17%, 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.
Clinton has about the Clinton County oil share of 1% and 1 points more electric heat than the county's 16% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US19045, checked 2026-10-19).
Clinton has 12,395 housing units, 41% built before 1940 and 82% before 1980, with 9% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1914430, checked 2026-10-19).
Clinton has 5 points more pre-1940 homes than Clinton County as a whole (36%) and 3 points fewer homes built after 2000 than the county's 12% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US19045, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Clinton home was built in 1953 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1914430, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1914430, checked 2026-10-19).
73% of Clinton homes are single-family detached, 8% are in two- to four-unit buildings and 14% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1914430, checked 2026-10-19).
With 73% detached houses and 8% in small multi-family buildings, a Clinton quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 31% of Clinton homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1914430, checked 2026-10-19), the landlord signs the quote in many of them.
Clinton has 5 points fewer detached houses than Clinton County overall (78%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US19045, checked 2026-10-19).
41% of Clinton homes were built before 1940 and 82% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1914430, checked 2026-10-19), so insulation is the first sizing question: an older home leaks more heat per square foot, and the installer runs a room-by-room heat-loss calculation to size the system for what the walls and windows actually hold in, not just the floor plan.
No electric utility is on file for Clinton 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 Clinton address before counting it. With 17% of Clinton homes already on electric heat and 81% 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 Clinton is $60,230 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1914430, 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: -4F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Clinton County row, 99% heating, PDF pages 37 to 41 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That -4F figure is the Clinton County cold-day number a Clinton heat pump is sized against, so ask the installer to show the system's heating output at -4F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 77% of Clinton on gas and 17% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Clinton house from before 1940 (41% of the 12,395 units) rarely matches a square-footage rule of thumb.
