Harrisburg / Manheim
Manheim has 5,027 residents (give or take 16) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4246888, checked 2026-10-19), about 3,637 people per square mile.
Manheim is about 27 miles from the Census center point for Harrisburg in a straight line and covers 1.382 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).
3,637 people per square mile puts Manheim in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 2,037 occupied homes in Manheim, 29% heat with natural gas, 41% with heating oil, 24% with electricity and 5% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4246888, checked 2026-10-19).
Heating oil is the largest single fuel in Manheim at 41%, ahead of gas at 29%, so the usual job here is an oil boiler or furnace coming out and a cold-climate heat pump going in, with the oil tank removed.
Manheim has 25 points more oil heat than Lancaster County as a whole, where 16% of homes burn oil, and 11 points less electric heat than the county's 35% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42071, checked 2026-10-19).
Manheim has 2,057 housing units, 33% built before 1940 and 87% before 1980, with 6% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4246888, checked 2026-10-19).
Manheim has 13 points more pre-1940 homes than Lancaster County as a whole (20%) and 15 points fewer homes built after 2000 than the county's 21% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US42071, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Manheim home was built in 1954 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4246888, checked 2026-10-19) and the median home has 6.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4246888, checked 2026-10-19).
62% of Manheim homes are single-family detached, 10% are in two- to four-unit buildings and 5% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4246888, checked 2026-10-19).
30% of Manheim homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4246888, checked 2026-10-19), so beside the 62% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Manheim has 7 points more detached houses than Lancaster County overall (55%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42071, checked 2026-10-19).
33% of Manheim homes were built before 1940 and 87% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4246888, 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 Manheim 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 Manheim is $81,273 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4246888, 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: 8F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Lancaster 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 8F figure is the Lancaster County cold-day number a Manheim heat pump is sized against, so ask the installer to show the system's heating output at 8F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 41% of the 2,037 occupied Manheim homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; a Manheim house from before 1940 (33% of the 2,057 units) rarely matches a square-footage rule of thumb.
