Philadelphia / Warminster
Warminster has 33,470 residents (give or take 33) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US4201780952, checked 2026-10-19), about 3,294 people per square mile.
Warminster is about 14 miles from the Census center point for Philadelphia in a straight line and covers 10.16 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 Warminster that is 18974 (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).
3,294 people per square mile puts Warminster in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 14,014 occupied homes in Warminster, 56% heat with natural gas, 13% with heating oil, 28% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US4201780952, checked 2026-10-19).
Gas heats 56% of Warminster against electricity at 28%, 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.
Warminster has 11 points less oil heat than Bucks County as a whole, where 24% of homes burn oil, and 3 points less electric heat than the county's 31% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42017, checked 2026-10-19).
Warminster has 14,536 housing units, 4% built before 1940 and 66% before 1980, with 22% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US4201780952, checked 2026-10-19).
Warminster has 6 points fewer pre-1940 homes than Bucks County as a whole (10%) and 7 points more homes built after 2000 than the county's 15% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US42017, checked 2026-10-19).
The median Warminster home was built in 1969 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US4201780952, checked 2026-10-19) and the median home has 6.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US4201780952, checked 2026-10-19).
54% of Warminster homes are single-family detached, 2% are in two- to four-unit buildings and 30% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US4201780952, checked 2026-10-19).
31% of Warminster homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US4201780952, checked 2026-10-19), so beside the 54% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Warminster has 9 points fewer detached houses than Bucks County overall (63%) and 16 points more five-plus-unit buildings than the county's 14% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42017, checked 2026-10-19).
66% of Warminster homes were built before 1980 and only 22% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US4201780952, 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 Warminster 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 Warminster address before counting it. With 28% of Warminster homes already on electric heat and 70% 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 Warminster 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 Warminster address before counting it.
Median household income in Warminster is $96,391 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US4201780952, 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: 6F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Bucks 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 6F figure is the Bucks County cold-day number a Warminster heat pump is sized against, so ask the installer to show the system's heating output at 6F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 56% of Warminster on gas and 28% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Warminster home has 6.2 rooms and was built around 1969, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
