Harrisburg / Pottsville
Pottsville has 13,364 residents (give or take 24) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4262432, checked 2026-10-19), about 3,208 people per square mile.
Pottsville is about 45 miles from the Census center point for Harrisburg in a straight line and covers 4.166 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).
Median household income in Pottsville is $54,332 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4262432, 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.
3,208 people per square mile puts Pottsville in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
33% of Pottsville homes are single-family detached, 15% are in two- to four-unit buildings and 15% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4262432, checked 2026-10-19).
43% of Pottsville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4262432, checked 2026-10-19), so beside the 33% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Pottsville has 25 points fewer detached houses than Schuylkill County overall (58%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42107, checked 2026-10-19).
43% of Pottsville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4262432, 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.
Of the 6,001 occupied homes in Pottsville, 33% heat with natural gas, 28% with heating oil, 28% with electricity and 5% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4262432, checked 2026-10-19).
Gas leads in Pottsville at 33%, but 33% of homes still burn delivered oil or propane, and those 1,980 or so homes are where a heat pump pays back fastest.
Pottsville has 19 points less oil heat than Schuylkill County as a whole, where 47% of homes burn oil, and 2 points more electric heat than the county's 26% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42107, checked 2026-10-19).
No electric utility is on file for Pottsville on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Pottsville has 6,972 housing units, 54% built before 1940 and 88% before 1980, with 3% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4262432, checked 2026-10-19).
Pottsville has 7 points more pre-1940 homes than Schuylkill County as a whole (47%) and 5 points fewer homes built after 2000 than the county's 8% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US42107, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Pottsville home was built in 1938 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4262432, 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=160XX00US4262432, checked 2026-10-19).
54% of Pottsville homes were built before 1940 and 88% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4262432, 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.
Heating design temperature: 7F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Schuylkill 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 7F figure is the Schuylkill County cold-day number a Pottsville heat pump is sized against, so ask the installer to show the system's heating output at 7F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 33% of Pottsville on gas and 28% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Pottsville house from before 1940 (54% of the 6,972 units) rarely matches a square-footage rule of thumb.
