Harrisburg / Indiana
Indiana has 14,212 residents (give or take 47) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4236816, checked 2026-10-19), about 8,080 people per square mile.
Indiana is about 122 miles from the Census center point for Harrisburg in a straight line and covers 1.759 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).
The quote form takes a ZIP code; for Indiana that is 15705 (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).
Median household income in Indiana is $40,857 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4236816, 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.
At 8,080 people per square mile, Indiana is dense enough that noise setback rules and outdoor-unit placement on a small lot are the first questions the installer works through.
48% of Indiana homes are single-family detached, 18% are in two- to four-unit buildings and 29% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4236816, checked 2026-10-19).
55% of Indiana homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4236816, checked 2026-10-19), so beside the 48% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Indiana has 19 points fewer detached houses than Indiana County overall (67%) and 17 points more five-plus-unit buildings than the county's 12% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42063, checked 2026-10-19).
55% of Indiana homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4236816, 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 5,218 occupied homes in Indiana, 71% heat with natural gas, 1% with heating oil, 25% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4236816, checked 2026-10-19).
Gas heats 71% of Indiana against electricity at 25%, 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.
Indiana has 15 points less oil heat than Indiana County as a whole, where 16% of homes burn oil, and 7 points more electric heat than the county's 18% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42063, checked 2026-10-19).
No electric utility is on file for Indiana on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Indiana has 6,684 housing units, 23% built before 1940 and 79% before 1980, with 11% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4236816, checked 2026-10-19).
Indiana tracks Indiana County on housing age, with the county at 22% pre-1940 and 13% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US42063, checked 2026-10-19).
The median Indiana home was built in 1957 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4236816, checked 2026-10-19) and the median home has 5.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4236816, checked 2026-10-19).
79% of Indiana homes were built before 1980 and only 11% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4236816, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
Heating design temperature: 5F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Indiana 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 Indiana County cold-day number a Indiana 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 71% of Indiana on gas and 25% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Indiana home has 5.1 rooms and was built around 1957, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
