The quote form takes a ZIP code; for Jackson that is 38305 (Census 2020 ZCTA to county subdivision and ZCTA to place relationship files, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt and https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_place20_natl.txt, checked 2026-10-19).
Of the 27,541 occupied homes in Jackson, 47% heat with natural gas, 0% with heating oil, 50% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4737640, checked 2026-10-19).
Electricity already heats 50% of Jackson homes, ahead of gas at 47%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Jackson has about the Madison County oil share of 0% and 3 points more electric heat than the county's 47% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US47113, checked 2026-10-19).
Jackson has 30,324 housing units, 6% built before 1940 and 43% before 1980, with 25% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4737640, checked 2026-10-19).
The median Jackson home was built in 1985 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4737640, 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=160XX00US4737640, checked 2026-10-19).
64% of Jackson homes are single-family detached, 14% are in two- to four-unit buildings and 18% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4737640, checked 2026-10-19).
49% of Jackson homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4737640, 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.

Heating design temperature: 19F.

That 19F figure is the Madison County cold-day number a Jackson 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 for the heat-loss calculation room by room; the median Jackson home has 5.5 rooms and was built around 1985, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
