Of the 368,788 occupied homes in Charlotte, 44% heat with natural gas, 0% with heating oil, 54% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3712000, checked 2026-10-19).
Charlotte has about the Mecklenburg County oil share of 0% and 2 points more 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).
Electricity already heats 54% of Charlotte homes, ahead of gas at 44%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
The median Charlotte home was built in 1995 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3712000, checked 2026-10-19) and the median home has 5.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3712000, checked 2026-10-19).
Charlotte has 399,305 housing units, 3% built before 1940 and 28% before 1980, with 43% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3712000, checked 2026-10-19).
51% of Charlotte homes are single-family detached, 4% are in two- to four-unit buildings and 35% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3712000, checked 2026-10-19).
49% of Charlotte homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3712000, checked 2026-10-19), so beside the 51% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.

Heating design temperature: 22F.

That 22F figure is the Mecklenburg County cold-day number a Charlotte 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 for the heat-loss calculation room by room; the median Charlotte home has 5.2 rooms and was built around 1995, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
