The quote form takes a ZIP code; for Austell that is 30106, 30111 (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 3,033 occupied homes in Austell, 67% heat with natural gas, 0% with heating oil, 30% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1304252, checked 2026-10-19).
Gas heats 67% of Austell against electricity at 30%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Austell has about the Cobb County oil share of 0% and the same 30% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US13067, checked 2026-10-19).
Austell has 3,176 housing units, 3% built before 1940 and 41% before 1980, with 43% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1304252, checked 2026-10-19).
Austell has 12 points more homes built after 2000 than the county's 31% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US13067, checked 2026-10-19).
The median Austell home was built in 1993 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1304252, checked 2026-10-19) and the median home has 6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1304252, checked 2026-10-19).
79% of Austell homes are single-family detached, 11% are in two- to four-unit buildings and 4% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1304252, checked 2026-10-19).
With 79% detached houses and 11% in small multi-family buildings, a Austell quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 35% of Austell homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1304252, checked 2026-10-19), the landlord signs the quote in many of them.
Austell has 14 points more detached houses than Cobb County overall (65%) and 18 points fewer five-plus-unit buildings than the county's 22% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US13067, checked 2026-10-19).
43% of Austell housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1304252, 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 Austell 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 Austell address before counting it. With 30% of Austell homes already on electric heat and 70% 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 Austell is $72,938 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1304252, 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: 23F.

That 23F figure is the Cobb County cold-day number a Austell heat pump is sized against, so ask the installer to show the system's heating output at 23F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 67% of Austell on gas and 30% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Austell home has 6 rooms and was built around 1993, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
