Atlanta / Hiram
Hiram has 5,231 residents (give or take 21) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1339076, checked 2026-10-19), about 1,330 people per square mile.
Hiram is about 21 miles from the Census center point for Atlanta in a straight line and covers 3.933 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 1,841 occupied homes in Hiram, 49% heat with natural gas, 0% with heating oil, 48% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1339076, checked 2026-10-19).
Gas heats 49% of Hiram against electricity at 48%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Hiram has about the Paulding County oil share of 0% and 5 points more electric heat than the county's 43% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US13223, checked 2026-10-19).
Hiram has 2,002 housing units, 0% built before 1940 and 25% before 1980, with 65% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1339076, checked 2026-10-19).
Hiram has 8 points more homes built after 2000 than the county's 57% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US13223, checked 2026-10-19).
The median Hiram home was built in 2004 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1339076, checked 2026-10-19) and the median home has 6.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1339076, checked 2026-10-19).
73% of Hiram homes are single-family detached, 0% 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=160XX00US1339076, checked 2026-10-19).
With 73% detached houses and 0% in small multi-family buildings, a Hiram quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 36% of Hiram homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1339076, checked 2026-10-19), the landlord signs the quote in many of them.
Hiram has 16 points fewer detached houses than Paulding County overall (89%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US13223, checked 2026-10-19).
65% of Hiram housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1339076, 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 Hiram 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 Hiram address before counting it. With 48% of Hiram homes already on electric heat and 51% 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 Hiram is $85,119 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1339076, 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: 22F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Paulding County row, 99% heating, PDF pages 20 to 27 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That 22F figure is the Paulding County cold-day number a Hiram 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 whether the quote is whole-home or partial-home, because with 49% of Hiram on gas and 48% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Hiram home has 6.2 rooms and was built around 2004, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
