Des Moines / North Liberty
North Liberty has 21,125 residents (give or take 43) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1957360, checked 2026-10-19), about 2,216 people per square mile.
North Liberty is about 104 miles from the Census center point for Des Moines in a straight line and covers 9.532 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 North Liberty that is 52317 (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 North Liberty is $102,102 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1957360, 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.
49% of North Liberty homes are single-family detached, 4% are in two- to four-unit buildings and 20% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1957360, checked 2026-10-19).
33% of North Liberty homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1957360, checked 2026-10-19), so beside the 49% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
North Liberty has 11 points fewer five-plus-unit buildings than the county's 31% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US19103, checked 2026-10-19).
Of the 8,159 occupied homes in North Liberty, 70% heat with natural gas, 0% with heating oil, 26% with electricity and 4% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1957360, checked 2026-10-19).
Gas heats 70% of North Liberty against electricity at 26%, 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.
North Liberty has about the Johnson County oil share of 0% and 2 points less electric heat than the county's 28% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US19103, checked 2026-10-19).
No electric utility is on file for North Liberty 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 North Liberty address before counting it. With 26% of North Liberty homes already on electric heat and 74% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
North Liberty has 8,739 housing units, 2% built before 1940 and 13% before 1980, with 64% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1957360, checked 2026-10-19).
North Liberty has 7 points fewer pre-1940 homes than Johnson County as a whole (9%) and 27 points more homes built after 2000 than the county's 37% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US19103, checked 2026-10-19).
The median North Liberty home was built in 2004 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1957360, checked 2026-10-19) and the median home has 5.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1957360, checked 2026-10-19).
64% of North Liberty housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1957360, 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.
Heating design temperature: -6F.

That -6F figure is the Johnson County cold-day number a North Liberty 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 70% of North Liberty on gas and 26% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median North Liberty home has 5.8 rooms and was built around 2004, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
