Heat pump installation in Lewisburg, PA - rebates, sizing and local data

Lewisburg in numbers

Lewisburg has 5,257 residents (give or take 34) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4242976, checked 2026-10-19), about 5,403 people per square mile.

Lewisburg is about 48 miles from the Census center point for Harrisburg in a straight line and covers 0.973 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 Lewisburg is $54,767 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4242976, 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.

5,403 people per square mile puts Lewisburg in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.

Multi-family first

43% of Lewisburg homes are single-family detached, 22% are in two- to four-unit buildings and 28% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4242976, checked 2026-10-19).

59% of Lewisburg homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4242976, checked 2026-10-19), so beside the 43% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.

Lewisburg has 29 points fewer detached houses than Union County overall (72%) and 21 points more five-plus-unit buildings than the county's 7% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42119, checked 2026-10-19).

59% of Lewisburg homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4242976, 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.

Heating fuel in Lewisburg

Of the 1,825 occupied homes in Lewisburg, 33% heat with natural gas, 19% with heating oil, 37% with electricity and 6% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4242976, checked 2026-10-19).

Electricity already heats 37% of Lewisburg homes, ahead of gas at 33%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.

Lewisburg has 9 points less oil heat than Union County as a whole, where 28% of homes burn oil, and 2 points less electric heat than the county's 39% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42119, checked 2026-10-19).

Your utility and the rebate

No electric utility is on file for Lewisburg on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.

Age of the stock

Lewisburg has 1,967 housing units, 56% built before 1940 and 90% before 1980, with 2% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4242976, checked 2026-10-19).

Lewisburg has 32 points more pre-1940 homes than Union County as a whole (24%) and 13 points fewer homes built after 2000 than the county's 15% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US42119, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.

The median Lewisburg home was built in 1938 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4242976, checked 2026-10-19) and the median home has 5.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4242976, checked 2026-10-19).

56% of Lewisburg homes were built before 1940 and 90% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4242976, 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.

Sizing for Union County

Heating design temperature: 7F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Union 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 Union County cold-day number a Lewisburg 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.

Next step

Ask for the heat-loss calculation room by room; a Lewisburg house from before 1940 (56% of the 1,967 units) rarely matches a square-footage rule of thumb.
