Nashville / Nashville
Nashville has 690,130 residents (give or take 74) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4752006, checked 2026-10-19), about 1,451 people per square mile.
Nashville is the city this door is named for; it covers 475.57 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 Nashville that is 37013, 37072, 37076, 37080, 37115, 37138, 37189, 37201 and 22 more (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).
49% of Nashville homes are single-family detached, 7% are in two- to four-unit buildings and 34% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4752006, checked 2026-10-19).
48% of Nashville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4752006, 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.
Of the 313,513 occupied homes in Nashville, 31% heat with natural gas, 0% with heating oil, 67% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4752006, checked 2026-10-19).
Electricity already heats 67% of Nashville homes, ahead of gas at 31%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Nashville has about the Davidson County oil share of 0% and the same 67% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US47037, checked 2026-10-19).
No electric utility is on file for Nashville on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Nashville has 344,794 housing units, 6% built before 1940 and 41% before 1980, with 35% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4752006, checked 2026-10-19).
The median Nashville home was built in 1987 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4752006, checked 2026-10-19) and the median home has 5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4752006, checked 2026-10-19).
Heating design temperature: 14F.

That 14F figure is the Davidson County cold-day number a Nashville heat pump is sized against, so ask the installer to show the system's heating output at 14F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Nashville home has 5 rooms and was built around 1987, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
