Philadelphia / Kennett Square
Kennett Square has 6,243 residents (give or take 33) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4239352, checked 2026-10-19), about 5,862 people per square mile.
Kennett Square is about 33 miles from the Census center point for Philadelphia in a straight line and covers 1.065 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).
5,862 people per square mile puts Kennett Square in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 2,209 occupied homes in Kennett Square, 41% heat with natural gas, 31% with heating oil, 21% with electricity and 5% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4239352, checked 2026-10-19).
Gas leads in Kennett Square at 41%, but 36% of homes still burn delivered oil or propane, and those 795 or so homes are where a heat pump pays back fastest.
Kennett Square has 13 points more oil heat than Chester County as a whole, where 18% of homes burn oil, and 10 points less electric heat than the county's 31% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42029, checked 2026-10-19).
Kennett Square has 2,340 housing units, 29% built before 1940 and 75% before 1980, with 9% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4239352, checked 2026-10-19).
Kennett Square has 16 points more pre-1940 homes than Chester County as a whole (13%) and 17 points fewer homes built after 2000 than the county's 26% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US42029, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Kennett Square home was built in 1957 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4239352, checked 2026-10-19) and the median home has 5.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4239352, checked 2026-10-19).
53% of Kennett Square homes are single-family detached, 10% are in two- to four-unit buildings and 22% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4239352, checked 2026-10-19).
44% of Kennett Square homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4239352, checked 2026-10-19), so beside the 53% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Kennett Square has 7 points fewer detached houses than Chester County overall (60%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42029, checked 2026-10-19).
44% of Kennett Square homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4239352, 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.
75% of Kennett Square homes were built before 1980 and only 9% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4239352, 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.
No electric utility is on file for Kennett Square on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
PPL Electric Savings Phase V heat pump rebate, run by PPL Electric Utilities, is a live program for Pennsylvania addresses and lists a standard figure of $225 (registry row 16 verified 2026-10-15, https://www.pplelectricsavings.com/ppl/media/allresrebates_612026.pdf, checked 2026-10-16); confirm eligibility for the Kennett Square address before counting it. With 21% of Kennett Square homes already on electric heat and 77% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
PECO heating and cooling rebates (ASHP), run by PECO, is a live program for Pennsylvania addresses and covers qualifying equipment at $1,950 per system (registry row 17 verified 2026-10-14, https://pecohomerebateprogram.com/heating-cooling-rebates.html, checked 2026-10-16); confirm eligibility for the Kennett Square address before counting it.
Duquesne Light residential HVAC instant discounts (ASHP), run by Duquesne Light, is a live program for Pennsylvania addresses and lists a standard figure of $215 (registry row 49 verified 2026-10-15, https://dlcinstantdiscount.com/wp-content/uploads/2026/08/DLC-Residential-HVAC-Product-Incentives-Customers-v260806.pdf, checked 2026-10-16); confirm eligibility for the Kennett Square address before counting it.
Median household income in Kennett Square is $80,505 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4239352, 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.

That 8F figure is the Chester County cold-day number a Kennett Square 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 whether the quote is whole-home or partial-home, because with 41% of Kennett Square on gas and 21% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Kennett Square home has 5.9 rooms and was built around 1957, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
