Of the 15,568 occupied homes in Germantown, 66% heat with natural gas, 0% with heating oil, 33% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4728960, checked 2026-10-19).
Gas heats 66% of Germantown against electricity at 33%, 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.
Germantown has about the Shelby County oil share of 0% and 20 points less electric heat than the county's 53% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US47157, checked 2026-10-19).
Germantown has 16,106 housing units, 1% built before 1940 and 43% before 1980, with 20% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4728960, checked 2026-10-19).
The median Germantown home was built in 1983 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4728960, checked 2026-10-19) and the median home has 8.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4728960, checked 2026-10-19).
84% of Germantown homes are single-family detached, 3% are in two- to four-unit buildings and 10% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4728960, checked 2026-10-19).
With 84% detached houses and 3% in small multi-family buildings, a Germantown quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 13% of Germantown homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4728960, checked 2026-10-19), the landlord signs the quote in many of them.

Heating design temperature: 20F.

That 20F figure is the Shelby County cold-day number a Germantown heat pump is sized against, so ask the installer to show the system's heating output at 20F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 66% of Germantown on gas and 33% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Germantown home has 8.1 rooms and was built around 1983, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
