Mendenhall is about 32 miles from the Census center point for Jackson in a straight line and covers 5.348 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 941 occupied homes in Mendenhall, 43% heat with natural gas, 0% with heating oil, 50% with electricity and 6% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2846600, checked 2026-10-19).
Electricity already heats 50% of Mendenhall homes, ahead of gas at 43%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Mendenhall has about the Simpson County oil share of 0% and 13 points less electric heat than the county's 63% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US28127, checked 2026-10-19).
Mendenhall has 1,089 housing units, 8% built before 1940 and 77% before 1980, with 4% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2846600, checked 2026-10-19).
Mendenhall has 4 points more pre-1940 homes than Simpson County as a whole (4%) and 26 points fewer homes built after 2000 than the county's 30% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US28127, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Mendenhall home was built in 1966 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2846600, checked 2026-10-19) and the median home has 5.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2846600, checked 2026-10-19).
78% of Mendenhall homes are single-family detached, 8% are in two- to four-unit buildings and 4% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2846600, checked 2026-10-19).
With 78% detached houses and 8% in small multi-family buildings, a Mendenhall quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 29% of Mendenhall homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2846600, checked 2026-10-19), the landlord signs the quote in many of them.
Mendenhall has 8 points more detached houses than Simpson County overall (70%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US28127, checked 2026-10-19).
77% of Mendenhall homes were built before 1980 and only 4% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2846600, 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 Mendenhall 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 Mendenhall is $40,141 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2846600, 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: 26F.

That 26F figure is the Simpson County cold-day number a Mendenhall heat pump is sized against, so ask the installer to show the system's heating output at 26F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Mendenhall home has 5.9 rooms and was built around 1966, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
