Atlanta / McDonough
McDonough has 30,947 residents (give or take 50) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1348624, checked 2026-10-19), about 2,313 people per square mile.
McDonough is about 27 miles from the Census center point for Atlanta in a straight line and covers 13.379 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).
Of the 10,886 occupied homes in McDonough, 38% heat with natural gas, 0% with heating oil, 59% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1348624, checked 2026-10-19).
Electricity already heats 59% of McDonough 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.
McDonough has about the Henry County oil share of 0% and 13 points more electric heat than the county's 46% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US13151, checked 2026-10-19).
McDonough has 11,619 housing units, 2% built before 1940 and 11% before 1980, with 78% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1348624, checked 2026-10-19).
McDonough has 25 points more homes built after 2000 than the county's 53% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US13151, checked 2026-10-19).
The median McDonough home was built in 2006 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1348624, checked 2026-10-19) and the median home has 5.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1348624, checked 2026-10-19).
64% of McDonough homes are single-family detached, 7% are in two- to four-unit buildings and 22% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1348624, checked 2026-10-19).
45% of McDonough homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1348624, checked 2026-10-19), so beside the 64% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
McDonough has 19 points fewer detached houses than Henry County overall (83%) and 12 points more five-plus-unit buildings than the county's 10% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US13151, checked 2026-10-19).
45% of McDonough homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1348624, 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.
78% of McDonough housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1348624, checked 2026-10-19), and homes that recent usually meet the insulation codes in place at the time, so a heat pump sized to the floor plan lands closer to the real load than it would in an older neighborhood.
No electric utility is on file for McDonough 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 McDonough address before counting it. With 59% of McDonough homes already on electric heat and 40% 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 McDonough is $75,343 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1348624, 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.

That 20F figure is the Henry County cold-day number a McDonough 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 McDonough home has 5.9 rooms and was built around 2006, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
