Of the 3,223 occupied homes in Charles City, 73% heat with natural gas, 0% with heating oil, 25% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1912765, checked 2026-10-19).
Gas heats 73% of Charles City against electricity at 25%, 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.
Charles City has about the Floyd County oil share of 0% and 5 points more electric heat than the county's 20% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US19067, checked 2026-10-19).

The median Charles City home was built in 1960 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1912765, checked 2026-10-19) and the median home has 5.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1912765, checked 2026-10-19).
78% of Charles City homes are single-family detached, 10% are in two- to four-unit buildings and 11% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1912765, checked 2026-10-19).
With 78% detached houses and 10% in small multi-family buildings, a Charles City quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 32% of Charles City homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1912765, checked 2026-10-19), the landlord signs the quote in many of them.
Charles City has 7 points fewer detached houses than Floyd County overall (85%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US19067, checked 2026-10-19).
90% of Charles City homes were built before 1980 and only 6% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1912765, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
No electric utility is on file for Charles City 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 Charles City address before counting it. With 25% of Charles City 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.
Median household income in Charles City is $59,180 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1912765, 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 -8F figure is the Floyd County cold-day number a Charles City heat pump is sized against, so ask the installer to show the system's heating output at -8F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 73% of Charles City on gas and 25% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Charles City home has 5.5 rooms and was built around 1960, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
