Atlanta / Carrollton
Carrollton has 27,392 residents (give or take 60) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1313492, checked 2026-10-19), about 1,188 people per square mile.
Carrollton is about 40 miles from the Census center point for Atlanta in a straight line and covers 23.054 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).
The quote form takes a ZIP code; for Carrollton that is 30118 (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).
Median household income in Carrollton is $54,379 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1313492, 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.
47% of Carrollton homes are single-family detached, 19% are in two- to four-unit buildings and 28% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1313492, checked 2026-10-19).
59% of Carrollton homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1313492, checked 2026-10-19), so beside the 47% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Carrollton has 26 points fewer detached houses than Carroll County overall (73%) and 20 points more five-plus-unit buildings than the county's 8% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US13045, checked 2026-10-19).
59% of Carrollton homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1313492, 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 9,992 occupied homes in Carrollton, 38% heat with natural gas, 0% with heating oil, 61% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1313492, checked 2026-10-19).
Electricity already heats 61% of Carrollton homes, ahead of gas at 38%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Carrollton has about the Carroll County oil share of 1% and 3 points more electric heat than the county's 58% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US13045, checked 2026-10-19).
No electric utility is on file for Carrollton 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 Carrollton address before counting it. With 61% of Carrollton homes already on electric heat and 39% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Carrollton has 10,843 housing units, 6% built before 1940 and 37% before 1980, with 36% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1313492, checked 2026-10-19).

That 20F figure is the Carroll County cold-day number a Carrollton heat pump is sized against, so ask the installer to show the system's heating output at 20F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Carrollton home has 5 rooms and was built around 1989, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
