The quote form takes a ZIP code; for Reston that is 20190, 20191, 20194 (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 Reston is $148,710 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5166672, 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.
4,198 people per square mile puts Reston in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
20% of Reston homes are single-family detached, 3% are in two- to four-unit buildings and 47% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5166672, checked 2026-10-19).
With 47% of Reston homes in buildings of five or more units and 20% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 39% of Reston homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5166672, checked 2026-10-19), the landlord signs the quote in many of them.

Of the 28,701 occupied homes in Reston, 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=160XX00US5166672, checked 2026-10-19).
Electricity already heats 50% of Reston 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.
Reston has about the Fairfax County oil share of 1% and 8 points more electric heat than the county's 42% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US51059, checked 2026-10-19).

That 14F figure is the Fairfax County cold-day number a Reston 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 Reston home has 5.3 rooms and was built around 1984, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
