Harrisburg / Nazareth
Nazareth has 6,043 residents (give or take 22) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4252808, checked 2026-10-19), about 3,813 people per square mile.
Nazareth is about 89 miles from the Census center point for Harrisburg in a straight line and covers 1.585 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 Nazareth is $56,855 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4252808, 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.
3,813 people per square mile puts Nazareth in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
34% of Nazareth homes are single-family detached, 27% are in two- to four-unit buildings and 24% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4252808, checked 2026-10-19).
58% of Nazareth homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4252808, checked 2026-10-19), so beside the 34% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Nazareth has 24 points fewer detached houses than Northampton County overall (58%) and 13 points more five-plus-unit buildings than the county's 11% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42095, checked 2026-10-19).
58% of Nazareth homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4252808, 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 2,994 occupied homes in Nazareth, 32% heat with natural gas, 30% with heating oil, 33% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4252808, checked 2026-10-19).
Electricity already heats 33% of Nazareth homes, ahead of gas at 32%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Nazareth has 9 points more oil heat than Northampton County as a whole, where 21% of homes burn oil, and 2 points more electric heat than the county's 31% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42095, checked 2026-10-19).
No electric utility is on file for Nazareth on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Nazareth has 3,326 housing units, 54% built before 1940 and 86% before 1980, with 9% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4252808, checked 2026-10-19).
Nazareth has 28 points more pre-1940 homes than Northampton County as a whole (26%) and 10 points fewer homes built after 2000 than the county's 19% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US42095, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Nazareth home was built in 1938 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4252808, checked 2026-10-19) and the median home has 4.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4252808, checked 2026-10-19).
54% of Nazareth homes were built before 1940 and 86% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4252808, 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: 5F.

That 5F figure is the Northampton County cold-day number a Nazareth 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 for the heat-loss calculation room by room; a Nazareth house from before 1940 (54% of the 3,326 units) rarely matches a square-footage rule of thumb.
