Of the 7,792 occupied homes in Erlanger, 56% heat with natural gas, 1% with heating oil, 39% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2125300, checked 2026-10-19).
Gas heats 56% of Erlanger against electricity at 39%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
Erlanger has about the Kenton County oil share of 1% and 2 points less electric heat than the county's 41% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US21117, checked 2026-10-19).
Erlanger has 8,180 housing units, 8% built before 1940 and 58% before 1980, with 18% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2125300, checked 2026-10-19).
Erlanger has 12 points fewer pre-1940 homes than Kenton County as a whole (20%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US21117, checked 2026-10-19).
The median Erlanger home was built in 1976 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2125300, checked 2026-10-19) and the median home has 6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2125300, checked 2026-10-19).
64% of Erlanger homes are single-family detached, 9% are in two- to four-unit buildings and 19% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2125300, checked 2026-10-19).
31% of Erlanger homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2125300, checked 2026-10-19), so beside the 64% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Duke Energy Kentucky lists Erlanger among the Kentucky communities it serves for electricity (Duke Energy Kentucky electric tariff Sheet No. 10, communities served, https://www.duke-energy.com/-/media/pdfs/for-your-home/rates/electric-ky/sheet-no10-index-ky-elec.pdf, checked 2026-10-19).

Median household income in Erlanger is $75,840 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2125300, 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.
Heating design temperature: 5F.

That 5F figure is the Kenton County cold-day number a Erlanger heat pump is sized against, so ask the installer to show the system's heating output at 5F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 56% of Erlanger on gas and 39% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Erlanger home has 6 rooms and was built around 1976, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
