Baltimore / Crofton
Crofton has 29,549 residents (give or take 1,790) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US2420875, checked 2026-10-19), about 4,470 people per square mile.
Crofton is about 20 miles from the Census center point for Baltimore in a straight line and covers 6.611 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 Crofton that is 21114 (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 Crofton is $150,577 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2420875, 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.
4,470 people per square mile puts Crofton in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
46% of Crofton homes are single-family detached, 0% are in two- to four-unit buildings and 8% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2420875, checked 2026-10-19).
18% of Crofton homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2420875, checked 2026-10-19), so beside the 46% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Crofton has 13 points fewer detached houses than Anne Arundel County overall (59%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US24003, checked 2026-10-19).
Of the 10,528 occupied homes in Crofton, 50% heat with natural gas, 2% with heating oil, 47% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2420875, checked 2026-10-19).
Gas heats 50% of Crofton against electricity at 47%, 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.
Crofton has 6 points less oil heat than Anne Arundel County as a whole, where 8% of homes burn oil, and 3 points less electric heat than the county's 50% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US24003, checked 2026-10-19).
No electric utility is on file for Crofton on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Crofton has 10,850 housing units, 0% built before 1940 and 40% before 1980, with 19% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2420875, checked 2026-10-19).
Crofton has 5 points fewer pre-1940 homes than Anne Arundel County as a whole (5%) and 6 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=050XX00US24003, checked 2026-10-19).
The median Crofton home was built in 1988 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2420875, checked 2026-10-19) and the median home has 7.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2420875, checked 2026-10-19).

That 17F figure is the Anne Arundel County cold-day number a Crofton heat pump is sized against, so ask the installer to show the system's heating output at 17F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 50% of Crofton on gas and 47% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Crofton home has 7.2 rooms and was built around 1988, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
