Philadelphia / Chester
Chester has 33,619 residents (give or take 59) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4213208, checked 2026-10-19), about 6,956 people per square mile.
Chester is about 17 miles from the Census center point for Philadelphia in a straight line and covers 4.833 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 Chester that is 19013 (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 Chester is $41,342 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4213208, 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.
6,956 people per square mile puts Chester in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
7% of Chester homes are single-family detached, 13% are in two- to four-unit buildings and 17% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4213208, checked 2026-10-19).
60% of Chester homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4213208, checked 2026-10-19), so beside the 7% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Chester has 37 points fewer detached houses than Delaware County overall (44%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42045, checked 2026-10-19).
With 60% of Chester homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4213208, checked 2026-10-19), most heat pump quotes here are landlord-driven: the landlord signs the contract and picks the equipment, and the tenant sees the lower bill.
Of the 12,537 occupied homes in Chester, 49% heat with natural gas, 18% with heating oil, 30% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4213208, checked 2026-10-19).
Gas leads in Chester at 49%, but 19% of homes still burn delivered oil or propane, and those 2,382 or so homes are where a heat pump pays back fastest.
Chester has 5 points more oil heat than Delaware County as a whole, where 13% of homes burn oil, and 7 points more electric heat than the county's 23% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42045, checked 2026-10-19).
No electric utility is on file for Chester 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 Chester address before counting it. With 30% of Chester homes already on electric heat and 68% 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 Chester address before counting it.

Chester has 14,929 housing units, 36% built before 1940 and 85% before 1980, with 7% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4213208, checked 2026-10-19).
Chester has 14 points more pre-1940 homes than Delaware County as a whole (22%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US42045, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Chester home was built in 1949 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4213208, checked 2026-10-19) and the median home has 5.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4213208, checked 2026-10-19).
36% of Chester homes were built before 1940 and 85% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4213208, 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: 11F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Delaware 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 11F figure is the Delaware County cold-day number a Chester heat pump is sized against, so ask the installer to show the system's heating output at 11F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 49% of Chester on gas and 30% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Chester house from before 1940 (36% of the 14,929 units) rarely matches a square-footage rule of thumb.
