Of the 5,491 occupied homes in Shepherdsville, 46% heat with natural gas, 0% with heating oil, 51% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2170086, checked 2026-10-19).
Electricity already heats 51% of Shepherdsville homes, ahead of gas at 46%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Shepherdsville has about the Bullitt County oil share of 0% and 2 points more electric heat than the county's 49% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US21029, checked 2026-10-19).
Shepherdsville has 5,903 housing units, 2% built before 1940 and 20% before 1980, with 39% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2170086, checked 2026-10-19).
Shepherdsville has 4 points more homes built after 2000 than the county's 35% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US21029, checked 2026-10-19).
The median Shepherdsville home was built in 1996 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2170086, checked 2026-10-19) and the median home has 5.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2170086, checked 2026-10-19).
68% of Shepherdsville homes are single-family detached, 7% are in two- to four-unit buildings and 13% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2170086, checked 2026-10-19).
26% of Shepherdsville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2170086, 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.
Shepherdsville has 11 points fewer detached houses than Bullitt County overall (79%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US21029, checked 2026-10-19).
No electric utility is on file for Shepherdsville on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in Shepherdsville is $71,476 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2170086, checked 2026-10-19); many state and utility heat pump rebate programs set higher incentive tiers for income-qualifying households, so the household income on the application, not the town median, decides which level applies.

That 10F figure is the Bullitt County cold-day number a Shepherdsville heat pump is sized against, so ask the installer to show the system's heating output at 10F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Shepherdsville home has 5.4 rooms and was built around 1996, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
