Atlanta / Lithonia
Lithonia has 2,622 residents (give or take 22) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1346860, checked 2026-10-19), about 2,825 people per square mile.
Lithonia is about 19 miles from the Census center point for Atlanta in a straight line and covers 0.928 square miles of land (Census 2024 Gazetteer internal points and land area, https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/, checked 2026-10-19).
Median household income in Lithonia is $61,713 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1346860, 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.
37% of Lithonia homes are single-family detached, 10% are in two- to four-unit buildings and 36% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1346860, checked 2026-10-19).
58% of Lithonia homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1346860, checked 2026-10-19), so beside the 37% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Lithonia has 19 points fewer detached houses than DeKalb County overall (56%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US13089, checked 2026-10-19).
58% of Lithonia homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1346860, 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.
Of the 1,005 occupied homes in Lithonia, 41% heat with natural gas, 0% with heating oil, 50% with electricity and 7% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1346860, checked 2026-10-19).
Electricity already heats 50% of Lithonia homes, ahead of gas at 41%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Lithonia has about the DeKalb County oil share of 0% and 10 points more electric heat than the county's 40% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US13089, checked 2026-10-19).
No electric utility is on file for Lithonia 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 Lithonia address before counting it. With 50% of Lithonia homes already on electric heat and 48% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Lithonia has 1,151 housing units, 16% built before 1940 and 56% before 1980, with 37% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1346860, checked 2026-10-19).
Lithonia has 13 points more pre-1940 homes than DeKalb County as a whole (3%) and 10 points more homes built after 2000 than the county's 27% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US13089, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Lithonia home was built in 1977 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1346860, checked 2026-10-19) and the median home has 4.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1346860, checked 2026-10-19).

That 22F figure is the DeKalb County cold-day number a Lithonia heat pump is sized against, so ask the installer to show the system's heating output at 22F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Lithonia home has 4.8 rooms and was built around 1977, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
