Pittsburgh / Mars
Mars has 1,285 residents (give or take 246) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4247672, checked 2026-10-19), about 2,734 people per square mile.
Mars is about 18 miles from the Census center point for Pittsburgh in a straight line and covers 0.47 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).
Of the 573 occupied homes in Mars, 69% heat with natural gas, 3% with heating oil, 25% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4247672, checked 2026-10-19).
Gas heats 69% of Mars against electricity at 25%, 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.
Mars has 3 points less oil heat than Butler County as a whole, where 6% of homes burn oil, and 6 points more electric heat than the county's 19% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42019, checked 2026-10-19).
Mars has 655 housing units, 34% built before 1940 and 84% before 1980, with 7% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4247672, checked 2026-10-19).
Mars has 18 points more pre-1940 homes than Butler County as a whole (16%) and 18 points fewer homes built after 2000 than the county's 25% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US42019, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Mars home was built in 1968 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4247672, 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=160XX00US4247672, checked 2026-10-19).
53% of Mars homes are single-family detached, 12% are in two- to four-unit buildings and 34% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4247672, checked 2026-10-19).
44% of Mars homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4247672, 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.
Mars has 17 points fewer detached houses than Butler County overall (70%) and 24 points more five-plus-unit buildings than the county's 10% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42019, checked 2026-10-19).
44% of Mars homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4247672, 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.
34% of Mars homes were built before 1940 and 84% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4247672, 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.
No electric utility is on file for Mars 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 Mars address before counting it. With 25% of Mars homes already on electric heat and 72% 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 Mars 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 Mars address before counting it.
Median household income in Mars is $50,938 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4247672, 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), Butler 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 Butler County cold-day number a Mars 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 69% of Mars on gas and 25% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Mars house from before 1940 (34% of the 655 units) rarely matches a square-footage rule of thumb.
