Harrisburg / Carbondale
Carbondale has 8,789 residents (give or take 65) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4211232, checked 2026-10-19), about 2,710 people per square mile.
Carbondale is about 115 miles from the Census center point for Harrisburg in a straight line and covers 3.243 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 3,751 occupied homes in Carbondale, 73% heat with natural gas, 2% with heating oil, 23% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4211232, checked 2026-10-19).
Gas heats 73% of Carbondale against electricity at 23%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
Carbondale has 6 points less oil heat than Lackawanna County as a whole, where 8% of homes burn oil, and 4 points more electric heat than the county's 19% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42069, checked 2026-10-19).
Carbondale has 4,224 housing units, 38% built before 1940 and 80% before 1980, with 3% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4211232, checked 2026-10-19).
Carbondale has 7 points fewer homes built after 2000 than the county's 10% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US42069, checked 2026-10-19).
The median Carbondale home was built in 1955 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4211232, checked 2026-10-19) and the median home has 5.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4211232, checked 2026-10-19).
53% of Carbondale homes are single-family detached, 27% are in two- to four-unit buildings and 14% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4211232, checked 2026-10-19).
49% of Carbondale homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4211232, checked 2026-10-19), so beside the 53% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Carbondale has 11 points fewer detached houses than Lackawanna County overall (64%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42069, checked 2026-10-19).
49% of Carbondale homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4211232, 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.
38% of Carbondale homes were built before 1940 and 80% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4211232, checked 2026-10-19), so insulation is the first sizing question: an older home leaks more heat per square foot, and the installer runs a room-by-room heat-loss calculation to size the system for what the walls and windows actually hold in, not just the floor plan.
No electric utility is on file for Carbondale on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in Carbondale is $47,716 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4211232, 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: 5F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Lackawanna County row, 99% heating, PDF pages 102 to 105 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 5F figure is the Lackawanna County cold-day number a Carbondale heat pump is sized against, so ask the installer to show the system's heating output at 5F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 73% of Carbondale on gas and 23% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Carbondale house from before 1940 (38% of the 4,224 units) rarely matches a square-footage rule of thumb.
