Of the 67,832 occupied homes in Clarksville, 22% heat with natural gas, 0% with heating oil, 75% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4715160, checked 2026-10-19).
Electricity already heats 75% of Clarksville homes, ahead of gas at 22%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Clarksville has about the Montgomery County oil share of 0% and the same 75% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US47125, checked 2026-10-19).
Clarksville has 72,320 housing units, 2% built before 1940 and 26% before 1980, with 45% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4715160, checked 2026-10-19).
The median Clarksville home was built in 1997 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4715160, checked 2026-10-19) and the median home has 5.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4715160, checked 2026-10-19).
67% of Clarksville homes are single-family detached, 11% are in two- to four-unit buildings and 14% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4715160, checked 2026-10-19).
44% of Clarksville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4715160, checked 2026-10-19), so beside the 67% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.

Heating design temperature: 12F.

That 12F figure is the Montgomery County cold-day number a Clarksville heat pump is sized against, so ask the installer to show the system's heating output at 12F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Clarksville home has 5.5 rooms and was built around 1997, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
