Of the 7,927 occupied homes in Hammond, 27% heat with natural gas, 0% with heating oil, 70% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2232755, checked 2026-10-19).
Electricity already heats 70% of Hammond homes, ahead of gas at 27%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Hammond has about the Tangipahoa Parish oil share of 0% and 3 points less electric heat than the county's 73% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US22105, checked 2026-10-19).
Hammond has 9,855 housing units, 3% built before 1940 and 43% before 1980, with 29% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2232755, checked 2026-10-19).
The median Hammond home was built in 1984 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2232755, checked 2026-10-19) and the median home has 5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2232755, checked 2026-10-19).
56% of Hammond homes are single-family detached, 13% 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=160XX00US2232755, checked 2026-10-19).
54% of Hammond homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2232755, checked 2026-10-19), so beside the 56% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.

Heating design temperature: 28F.

That 28F figure is the Tangipahoa Parish cold-day number a Hammond heat pump is sized against, so ask the installer to show the system's heating output at 28F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Hammond home has 5 rooms and was built around 1984, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
