St. Louis / Nixa
Nixa has 24,836 residents (give or take 32) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US2952616, checked 2026-10-19), about 2,667 people per square mile.
Nixa is about 199 miles from the Census center point for St. Louis in a straight line and covers 9.312 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).
Of the 9,226 occupied homes in Nixa, 68% heat with natural gas, 0% with heating oil, 27% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2952616, checked 2026-10-19).
Gas heats 68% of Nixa against electricity at 27%, 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.
Nixa has about the Christian County oil share of 0% and 10 points less electric heat than the county's 37% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US29043, checked 2026-10-19).
Nixa has 9,415 housing units, 1% built before 1940 and 15% before 1980, with 51% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2952616, checked 2026-10-19).
Nixa has 3 points fewer pre-1940 homes than Christian County as a whole (4%) and 3 points more homes built after 2000 than the county's 48% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US29043, checked 2026-10-19).
The median Nixa home was built in 2000 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2952616, 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=160XX00US2952616, checked 2026-10-19).
77% of Nixa homes are single-family detached, 7% are in two- to four-unit buildings and 8% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2952616, checked 2026-10-19).
With 77% detached houses and 7% in small multi-family buildings, a Nixa quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 33% of Nixa homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2952616, checked 2026-10-19), the landlord signs the quote in many of them.
51% of Nixa housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2952616, 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.
No electric utility is on file for Nixa on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in Nixa is $83,385 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2952616, 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: 11F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Christian County row, 99% heating, PDF pages 68 to 73 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 11F figure is the Christian County cold-day number a Nixa heat pump is sized against, so ask the installer to show the system's heating output at 11F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 68% of Nixa on gas and 27% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Nixa home has 5.6 rooms and was built around 2000, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
