Baltimore / Cumberland
Cumberland has 18,804 residents (give or take 32) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US2421325, checked 2026-10-19), about 1,856 people per square mile.
Cumberland is about 117 miles from the Census center point for Baltimore in a straight line and covers 10.131 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 8,405 occupied homes in Cumberland, 70% heat with natural gas, 2% with heating oil, 24% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2421325, checked 2026-10-19).
Gas heats 70% of Cumberland against electricity at 24%, 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.
Cumberland has 6 points less oil heat than Allegany County as a whole, where 8% of homes burn oil, and 6 points less electric heat than the county's 30% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US24001, checked 2026-10-19).
Cumberland has 10,610 housing units, 48% built before 1940 and 87% before 1980, with 4% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2421325, checked 2026-10-19).
Cumberland has 16 points more pre-1940 homes than Allegany County as a whole (32%) and 4 points fewer homes built after 2000 than the county's 8% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US24001, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Cumberland home was built in 1943 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2421325, 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=160XX00US2421325, checked 2026-10-19).
59% of Cumberland homes are single-family detached, 15% 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=160XX00US2421325, checked 2026-10-19).
40% of Cumberland homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2421325, checked 2026-10-19), so beside the 59% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Cumberland has 13 points fewer detached houses than Allegany County overall (72%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US24001, checked 2026-10-19).
40% of Cumberland homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2421325, 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.
48% of Cumberland homes were built before 1940 and 87% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2421325, 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 Cumberland on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in Cumberland is $48,162 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2421325, 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: 10F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Allegany County row, 99% heating, PDF pages 55 to 56 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 10F figure is the Allegany County cold-day number a Cumberland heat pump is sized against, so ask the installer to show the system's heating output at 10F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 70% of Cumberland on gas and 24% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Cumberland house from before 1940 (48% of the 10,610 units) rarely matches a square-footage rule of thumb.
