Arlington / Arlington
Arlington has 236,254 residents (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US5101390072, checked 2026-10-19), about 9,088 people per square mile.
Arlington is the city this door is named for; it covers 25.997 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 Arlington that is 22201, 22202, 22203, 22204, 22205, 22206, 22207, 22209 and 3 more (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 Arlington is $142,114 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US5101390072, 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.
At 9,088 people per square mile, Arlington is dense enough that noise setback rules and outdoor-unit placement on a small lot are the first questions the installer works through.
25% of Arlington homes are single-family detached, 5% are in two- to four-unit buildings and 61% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US5101390072, checked 2026-10-19).
With 61% of Arlington homes in buildings of five or more units and 25% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 59% of Arlington homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US5101390072, checked 2026-10-19), the landlord signs the quote in many of them.
59% of Arlington homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US5101390072, 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 112,027 occupied homes in Arlington, 45% heat with natural gas, 1% with heating oil, 51% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US5101390072, checked 2026-10-19).
Electricity already heats 51% of Arlington homes, ahead of gas at 45%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Arlington has about the Arlington County oil share of 1% and the same 51% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US51013, checked 2026-10-19).
No electric utility is on file for Arlington on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Arlington has 121,970 housing units, 8% built before 1940 and 53% before 1980, with 27% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US5101390072, checked 2026-10-19).
Arlington tracks Arlington County on housing age, with the county at 8% pre-1940 and 27% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US51013, checked 2026-10-19).
The median Arlington home was built in 1976 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US5101390072, checked 2026-10-19) and the median home has 4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US5101390072, checked 2026-10-19).

That 14F figure is the Arlington County cold-day number a Arlington heat pump is sized against, so ask the installer to show the system's heating output at 14F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Arlington home has 4 rooms and was built around 1976, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
