Of the 2,848 occupied homes in St. Martinville, 32% heat with natural gas, 0% with heating oil, 67% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2267600, checked 2026-10-19).
Electricity already heats 67% of St. Martinville homes, ahead of gas at 32%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
St. Martinville has about the St. Martin Parish oil share of 0% and 17 points less electric heat than the county's 84% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US22099, checked 2026-10-19).
St. Martinville has 3,466 housing units, 6% built before 1940 and 64% before 1980, with 13% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2267600, checked 2026-10-19).

The median St. Martinville home was built in 1969 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2267600, checked 2026-10-19) and the median home has 5.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2267600, checked 2026-10-19).
77% of St. Martinville homes are single-family detached, 9% 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=160XX00US2267600, checked 2026-10-19).
With 77% detached houses and 9% in small multi-family buildings, a St. Martinville quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 43% of St. Martinville homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2267600, checked 2026-10-19), the landlord signs the quote in many of them.
St. Martinville has 7 points more detached houses than St. Martin Parish overall (70%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US22099, checked 2026-10-19).
43% of St. Martinville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2267600, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
64% of St. Martinville homes were built before 1980 and only 13% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2267600, 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 St. Martinville 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 St. Martinville is $36,130 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2267600, 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: 31F.

That 31F figure is the St. Martin Parish cold-day number a St. Martinville heat pump is sized against, so ask the installer to show the system's heating output at 31F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median St. Martinville home has 5.2 rooms and was built around 1969, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
