Nashville / Union City
Union City has 10,982 residents (give or take 50) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4775940, checked 2026-10-19), about 907 people per square mile.
Union City is about 127 miles from the Census center point for Nashville in a straight line and covers 12.108 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 4,340 occupied homes in Union City, 55% heat with natural gas, 0% with heating oil, 44% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4775940, checked 2026-10-19).
Gas heats 55% of Union City against electricity at 44%, 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.
Union City has about the Obion County oil share of 0% and 11 points less electric heat than the county's 55% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US47131, checked 2026-10-19).
Union City has 4,901 housing units, 9% built before 1940 and 64% before 1980, with 14% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4775940, checked 2026-10-19).
The median Union City home was built in 1970 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4775940, checked 2026-10-19) and the median home has 5.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4775940, checked 2026-10-19).
68% of Union City homes are single-family detached, 18% are in two- to four-unit buildings and 6% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4775940, checked 2026-10-19).
47% of Union City homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4775940, checked 2026-10-19), so beside the 68% 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 Union City on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Heating design temperature: 19F.

That 19F figure is the Obion County cold-day number a Union City heat pump is sized against, so ask the installer to show the system's heating output at 19F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 55% of Union City on gas and 44% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Union City home has 5.8 rooms and was built around 1970, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
