Pittsburgh / Mount Lebanon
Mount Lebanon is about 6 miles from the Census center point for Pittsburgh in a straight line and covers 6.078 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).
Mount Lebanon has 33,370 residents (give or take 58) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US4200351696, checked 2026-10-19), about 5,490 people per square mile.
The quote form takes a ZIP code; for Mount Lebanon that is 15216, 15228, 15243 (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).
5,490 people per square mile puts Mount Lebanon in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 13,646 occupied homes in Mount Lebanon, 82% heat with natural gas, 1% with heating oil, 14% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US4200351696, checked 2026-10-19).
Mount Lebanon has about the Allegheny County oil share of 1% and 2 points less electric heat than the county's 16% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US42003, checked 2026-10-19).
Gas heats 82% of Mount Lebanon against electricity at 14%, 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.
The median Mount Lebanon home was built in 1953 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US4200351696, checked 2026-10-19) and the median home has 6.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US4200351696, checked 2026-10-19).
Mount Lebanon has 14,640 housing units, 31% built before 1940 and 88% before 1980, with 4% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US4200351696, checked 2026-10-19).
Mount Lebanon has 3 points more pre-1940 homes than Allegheny County as a whole (28%) and 7 points fewer homes built after 2000 than the county's 11% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US42003, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
31% of Mount Lebanon homes were built before 1940 and 88% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US4200351696, 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.
68% of Mount Lebanon homes are single-family detached, 5% 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=060XX00US4200351696, checked 2026-10-19).
28% of Mount Lebanon homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US4200351696, checked 2026-10-19), so beside the 68% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Mount Lebanon has 6 points more detached houses than Allegheny County overall (62%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US42003, checked 2026-10-19).
No electric utility is on file for Mount Lebanon 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 Mount Lebanon address before counting it. With 14% of Mount Lebanon homes already on electric heat and 84% 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 Mount Lebanon 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 Mount Lebanon address before counting it.
Median household income in Mount Lebanon is $123,771 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US4200351696, 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: 5F.

That 5F figure is the Allegheny County cold-day number a Mount Lebanon 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.
Ask whether the quote is whole-home or partial-home, because with 82% of Mount Lebanon on gas and 14% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Mount Lebanon house from before 1940 (31% of the 14,640 units) rarely matches a square-footage rule of thumb.
