The quote form takes a ZIP code; for Biloxi that is 39530, 39531, 39532, 39534 (Census 2020 ZCTA to county subdivision and ZCTA to place relationship files, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt and https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_place20_natl.txt, checked 2026-10-19).
Of the 19,914 occupied homes in Biloxi, 22% heat with natural gas, 0% with heating oil, 76% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2806220, checked 2026-10-19).
Electricity already heats 76% of Biloxi homes, ahead of gas at 22%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Biloxi has about the Harrison County oil share of 0% and the same 76% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US28047, checked 2026-10-19).
Biloxi has 23,033 housing units, 3% built before 1940 and 39% before 1980, with 38% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2806220, checked 2026-10-19).
Biloxi has 3 points fewer homes built after 2000 than the county's 41% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US28047, checked 2026-10-19).
The median Biloxi home was built in 1990 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2806220, checked 2026-10-19) and the median home has 5.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2806220, checked 2026-10-19).
53% of Biloxi homes are single-family detached, 6% are in two- to four-unit buildings and 31% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2806220, checked 2026-10-19).
50% of Biloxi homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2806220, checked 2026-10-19), so beside the 53% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Biloxi has 13 points fewer detached houses than Harrison County overall (66%) and 14 points more five-plus-unit buildings than the county's 17% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US28047, checked 2026-10-19).
50% of Biloxi homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2806220, 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.
No electric utility is on file for Biloxi 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 Biloxi is $57,204 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2806220, 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: 29F.

That 29F figure is the Harrison County cold-day number a Biloxi heat pump is sized against, so ask the installer to show the system's heating output at 29F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Biloxi home has 5.1 rooms and was built around 1990, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
