Arlington / Falls Church
Falls Church has 14,710 residents (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5127200, checked 2026-10-19), about 7,190 people per square mile.
Falls Church is about 4 miles from the Census center point for Arlington in a straight line and covers 2.046 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 Falls Church that is 22046 (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 Falls Church is $143,262 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5127200, 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.
7,190 people per square mile puts Falls Church in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
37% of Falls Church homes are single-family detached, 5% are in two- to four-unit buildings and 49% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5127200, checked 2026-10-19).
With 49% of Falls Church homes in buildings of five or more units and 37% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 47% of Falls Church homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5127200, checked 2026-10-19), the landlord signs the quote in many of them.
47% of Falls Church homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5127200, 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.
Of the 6,273 occupied homes in Falls Church, 51% heat with natural gas, 0% with heating oil, 45% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5127200, checked 2026-10-19).
Gas heats 51% of Falls Church against electricity at 45%, 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.
Falls Church has about the Falls Church city oil share of 0% and the same 45% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US51610, checked 2026-10-19).
No electric utility is on file for Falls Church on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Falls Church has 6,585 housing units, 6% built before 1940 and 61% before 1980, with 28% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5127200, checked 2026-10-19).
Falls Church tracks Falls Church city on housing age, with the county at 6% pre-1940 and 28% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US51610, checked 2026-10-19).
The median Falls Church home was built in 1971 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5127200, checked 2026-10-19) and the median home has 4.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5127200, checked 2026-10-19).
61% of Falls Church homes were built before 1980 and only 28% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5127200, 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.
Heating design temperature: 12F.

That 12F figure is the Falls Church city cold-day number a Falls Church heat pump is sized against, so ask the installer to show the system's heating output at 12F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 51% of Falls Church on gas and 45% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Falls Church home has 4.9 rooms and was built around 1971, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
