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

Clarks Summit in Lackawanna County

Clarks Summit has 5,073 residents (give or take 27) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4213880, checked 2026-10-19), about 3,201 people per square mile.

Clarks Summit is about 104 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).

3,201 people per square mile puts Clarks Summit in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.

Fuel mix

Of the 2,317 occupied homes in Clarks Summit, 79% heat with natural gas, 2% with heating oil, 18% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4213880, checked 2026-10-19).

Gas heats 79% of Clarks Summit against electricity at 18%, 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.

Clarks Summit has 6 points less oil heat than Lackawanna County as a whole, where 8% of homes burn oil, and 1 points less electric heat than the county's 19% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42069, checked 2026-10-19).

The median Clarks Summit home was built in 1966 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4213880, checked 2026-10-19) and the median home has 6.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4213880, checked 2026-10-19).

81% of Clarks Summit homes are single-family detached, 10% are in two- to four-unit buildings and 6% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4213880, checked 2026-10-19).

With 81% detached houses and 10% in small multi-family buildings, a Clarks Summit quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 27% of Clarks Summit homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4213880, checked 2026-10-19), the landlord signs the quote in many of them.

Clarks Summit has 17 points more detached houses than Lackawanna County overall (64%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42069, checked 2026-10-19).

74% of Clarks Summit homes were built before 1980 and only 10% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4213880, 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.

Rebate path

No electric utility is on file for Clarks Summit 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 Clarks Summit is $92,083 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4213880, 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.

Cold-day number

Heating design temperature: 5F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Lackawanna 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 Lackawanna County cold-day number a Clarks Summit 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.

Next step

Ask whether the quote is whole-home or partial-home, because with 79% of Clarks Summit on gas and 18% already electric the two paths carry different rebate figures and different sizing.

Ask for the heat-loss calculation room by room; the median Clarks Summit home has 6.3 rooms and was built around 1966, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
