The quote form takes a ZIP code; for Tybee Island that is 31328 (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 1,464 occupied homes in Tybee Island, 1% heat with natural gas, 0% with heating oil, 96% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1378036, checked 2026-10-19).
Tybee Island has about the Chatham County oil share of 0% and 25 points more electric heat than the county's 71% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US13051, checked 2026-10-19).
Electricity already heats 96% of Tybee Island homes, ahead of propane at 3%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
The median Tybee Island home was built in 1984 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1378036, checked 2026-10-19) and the median home has 5.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1378036, checked 2026-10-19).
Tybee Island has 3,227 housing units, 12% 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=160XX00US1378036, checked 2026-10-19).
Tybee Island has 3 points more pre-1940 homes than Chatham County as a whole (9%) and 5 points fewer homes built after 2000 than the county's 34% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US13051, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
67% of Tybee Island homes are single-family detached, 14% are in two- to four-unit buildings and 11% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1378036, checked 2026-10-19).
11% of Tybee Island homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1378036, checked 2026-10-19), so beside the 67% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Tybee Island has 5 points more detached houses than Chatham County overall (62%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US13051, checked 2026-10-19).
Only 11% of Tybee Island homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1378036, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.
No electric utility is on file for Tybee Island on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Georgia Power Home Energy Improvement Program heat pump conversion, run by Georgia Power, is a live program for Georgia addresses and covers qualifying equipment at $1,850 per system (registry row 28 verified 2026-10-14, https://www.georgiapower.com/residential/solutions/home-solutions.html, checked 2026-10-16); confirm eligibility for the Tybee Island address before counting it. With 96% of Tybee Island homes already on electric heat and 4% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in Tybee Island is $120,479 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1378036, 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 Chatham County cold-day number a Tybee Island 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 Tybee Island home has 5.5 rooms and was built around 1984, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
