Jackson / Louisville
Louisville has 5,983 residents (give or take 29) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US2842280, checked 2026-10-19), about 396 people per square mile.
Louisville is about 87 miles from the Census center point for Jackson in a straight line and covers 15.098 square miles of land (Census 2024 Gazetteer internal points and land area, https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/, checked 2026-10-19).
Louisville is spread out at 396 people per square mile across 15.098 square miles of land, so a long refrigerant line run between the outdoor unit and the farthest indoor head is the sizing question an installer checks first.
Of the 2,552 occupied homes in Louisville, 55% heat with natural gas, 0% with heating oil, 41% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2842280, checked 2026-10-19).
Gas heats 55% of Louisville against electricity at 41%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Louisville has about the Winston County oil share of 1% and 4 points less electric heat than the county's 45% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US28159, checked 2026-10-19).
Louisville has 2,723 housing units, 6% built before 1940 and 69% before 1980, with 16% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2842280, checked 2026-10-19).
Louisville has 4 points fewer homes built after 2000 than the county's 20% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US28159, checked 2026-10-19).
The median Louisville home was built in 1974 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2842280, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2842280, checked 2026-10-19).
79% of Louisville homes are single-family detached, 9% 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=160XX00US2842280, checked 2026-10-19).
With 79% detached houses and 9% in small multi-family buildings, a Louisville quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 38% of Louisville homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2842280, checked 2026-10-19), the landlord signs the quote in many of them.
69% of Louisville homes were built before 1980 and only 16% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2842280, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
No electric utility is on file for Louisville 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 Louisville is $36,985 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2842280, 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: 24F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Winston County row, 99% heating, PDF pages 64 to 68 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That 24F figure is the Winston County cold-day number a Louisville heat pump is sized against, so ask the installer to show the system's heating output at 24F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 55% of Louisville on gas and 41% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Louisville home has 5.6 rooms and was built around 1974, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
