Of the 95,310 occupied homes in Huntsville, 23% heat with natural gas, 0% with heating oil, 75% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0137000, checked 2026-10-19).
Electricity already heats 75% of Huntsville homes, ahead of gas at 23%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Huntsville has about the Madison County oil share of 0% and 1 points more electric heat than the county's 74% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US01089, checked 2026-10-19).
Huntsville has 104,388 housing units, 3% built before 1940 and 44% before 1980, with 33% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0137000, checked 2026-10-19).
The median Huntsville home was built in 1985 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0137000, checked 2026-10-19) and the median home has 5.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0137000, checked 2026-10-19).
63% of Huntsville homes are single-family detached, 8% are in two- to four-unit buildings and 24% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0137000, checked 2026-10-19).
42% of Huntsville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0137000, checked 2026-10-19), so beside the 63% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
No electric utility is on file for Huntsville on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Alabama Power gas-furnace-to-heat-pump rebate, run by Alabama Power, is a live program for Alabama addresses and lists a standard figure of $1,000 (registry row 29 verified 2026-10-14, https://www.alabamapower.com/residential/save-money-and-energy/rebates-and-incentives.html, checked 2026-10-16); confirm eligibility for the Huntsville address before counting it. With 75% of Huntsville homes already on electric heat and 24% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
TVA EnergyRight heat pump rebate (north Alabama), run by TVA EnergyRight, is a live program for Alabama addresses and lists a standard figure of $500 (registry row 30 verified 2026-10-14, https://energyright.com/residential/rebates/heat-pump/, checked 2026-10-16); confirm eligibility for the Huntsville address before counting it.
Heating design temperature: 16F.

That 16F figure is the Madison County cold-day number a Huntsville heat pump is sized against, so ask the installer to show the system's heating output at 16F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Huntsville home has 5.8 rooms and was built around 1985, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
