Charlotte / Cornelius
Cornelius is about 18 miles from the Census center point for Charlotte in a straight line and covers 12.694 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).
Cornelius has 32,783 residents (give or take 60) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3714700, checked 2026-10-19), about 2,583 people per square mile.
The quote form takes a ZIP code; for Cornelius that is 28031 (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 13,884 occupied homes in Cornelius, 57% heat with natural gas, 0% with heating oil, 42% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3714700, checked 2026-10-19).
Cornelius has about the Mecklenburg County oil share of 0% and 10 points less electric heat than the county's 52% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US37119, checked 2026-10-19).
Gas heats 57% of Cornelius against electricity at 42%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas boiler stays for the deepest cold, or a whole-home system when the house is ready for it.
The median Cornelius home was built in 2002 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3714700, checked 2026-10-19) and the median home has 6.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3714700, checked 2026-10-19).
Cornelius has 14,956 housing units, 1% built before 1940 and 8% before 1980, with 56% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3714700, checked 2026-10-19).
60% of Cornelius homes are single-family detached, 4% are in two- to four-unit buildings and 25% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3714700, checked 2026-10-19).
30% of Cornelius homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3714700, checked 2026-10-19), so beside the 60% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
No electric utility is on file for Cornelius on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Heating design temperature: 22F.

That 22F figure is the Mecklenburg County cold-day number a Cornelius heat pump is sized against, so ask the installer to show the system's heating output at 22F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 57% of Cornelius on gas and 42% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Cornelius home has 6.4 rooms and was built around 2002, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
