Atlanta / Alpharetta
Alpharetta is about 23 miles from the Census center point for Atlanta in a straight line and covers 26.9 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).
Alpharetta has 66,855 residents (give or take 68) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1301696, checked 2026-10-19), about 2,485 people per square mile.
The quote form takes a ZIP code; for Alpharetta that is 30005, 30009, 30022 (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 25,032 occupied homes in Alpharetta, 60% heat with natural gas, 0% with heating oil, 37% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1301696, checked 2026-10-19).
Alpharetta has about the Fulton County oil share of 0% and 12 points less electric heat than the county's 49% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US13121, checked 2026-10-19).
Gas heats 60% of Alpharetta against electricity at 37%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
The median Alpharetta home was built in 1996 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1301696, checked 2026-10-19) and the median home has 6.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1301696, checked 2026-10-19).
Alpharetta has 26,223 housing units, 1% built before 1940 and 8% before 1980, with 36% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1301696, checked 2026-10-19).
Alpharetta has 5 points fewer pre-1940 homes than Fulton County as a whole (6%) and 4 points fewer homes built after 2000 than the county's 40% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US13121, checked 2026-10-19).
55% of Alpharetta homes are single-family detached, 3% are in two- to four-unit buildings and 30% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1301696, checked 2026-10-19).
35% of Alpharetta homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1301696, checked 2026-10-19), so beside the 55% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Alpharetta has 9 points more detached houses than Fulton County overall (46%) and 11 points fewer five-plus-unit buildings than the county's 41% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US13121, checked 2026-10-19).
No electric utility is on file for Alpharetta 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 Alpharetta address before counting it. With 37% of Alpharetta homes already on electric heat and 62% 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 Alpharetta is $147,612 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1301696, 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: 20F.

That 20F figure is the Fulton County cold-day number a Alpharetta 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 whether the quote is whole-home or partial-home, because with 60% of Alpharetta on gas and 37% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Alpharetta home has 6.3 rooms and was built around 1996, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
