Madisonville is about 116 miles from the Census center point for Louisville in a straight line and covers 17.867 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).
Of the 8,271 occupied homes in Madisonville, 60% heat with natural gas, 0% 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=160XX00US2149368, checked 2026-10-19).
Gas heats 60% of Madisonville 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.
Madisonville has about the Hopkins County oil share of 0% and 11 points less electric heat than the county's 50% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US21107, checked 2026-10-19).
Madisonville has 9,565 housing units, 7% built before 1940 and 61% before 1980, with 12% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2149368, checked 2026-10-19).
Madisonville has 5 points fewer homes built after 2000 than the county's 17% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US21107, checked 2026-10-19).
The median Madisonville home was built in 1975 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2149368, checked 2026-10-19) and the median home has 5.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2149368, checked 2026-10-19).
74% of Madisonville homes are single-family detached, 11% are in two- to four-unit buildings and 9% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2149368, checked 2026-10-19).
With 74% detached houses and 11% in small multi-family buildings, a Madisonville quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 37% of Madisonville homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2149368, checked 2026-10-19), the landlord signs the quote in many of them.
61% of Madisonville homes were built before 1980 and only 12% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2149368, 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 Madisonville 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 Madisonville is $53,860 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2149368, 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: 10F.

That 10F figure is the Hopkins County cold-day number a Madisonville 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 whether the quote is whole-home or partial-home, because with 60% of Madisonville 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 Madisonville home has 5.7 rooms and was built around 1975, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
