Arlington / Alexandria
Alexandria has 156,976 residents (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5101000, checked 2026-10-19), about 10,511 people per square mile.
Alexandria is about 4 miles from the Census center point for Arlington in a straight line and covers 14.935 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 Alexandria that is 22301, 22302, 22304, 22305, 22311, 22314 (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 Alexandria is $119,681 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5101000, 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 10,511 people per square mile, Alexandria is dense enough that noise setback rules and outdoor-unit placement on a small lot are the first questions the installer works through.
14% of Alexandria homes are single-family detached, 4% 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=160XX00US5101000, checked 2026-10-19).
With 61% of Alexandria homes in buildings of five or more units and 14% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 58% of Alexandria homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5101000, checked 2026-10-19), the landlord signs the quote in many of them.
58% of Alexandria homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5101000, 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 76,096 occupied homes in Alexandria, 47% heat with natural gas, 1% with heating oil, 50% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5101000, checked 2026-10-19).
Electricity already heats 50% of Alexandria homes, ahead of gas at 47%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Alexandria has about the Alexandria city oil share of 1% and the same 50% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US51510, checked 2026-10-19).
No electric utility is on file for Alexandria on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Alexandria has 80,844 housing units, 9% built before 1940 and 60% before 1980, with 22% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5101000, checked 2026-10-19).
Alexandria tracks Alexandria city on housing age, with the county at 9% pre-1940 and 22% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US51510, checked 2026-10-19).
The median Alexandria home was built in 1974 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5101000, checked 2026-10-19) and the median home has 4.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5101000, checked 2026-10-19).
60% of Alexandria homes were built before 1980 and only 22% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5101000, 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: 14F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Alexandria city row, 99% heating, PDF pages 127 to 133 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 14F figure is the Alexandria city cold-day number a Alexandria 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 Alexandria home has 4.1 rooms and was built around 1974, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
