Clifton is about 17 miles from the Census center point for Arlington in a straight line and covers 0.245 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 median Clifton home was built in 1938 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5117376, checked 2026-10-19) and the median home has 10 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5117376, checked 2026-10-19).
No electric utility is on file for Clifton on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in Clifton is $232,500 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5117376, 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.
Heating design temperature: 14F.

That 14F figure is the Fairfax County cold-day number a Clifton 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 Clifton home has 10 rooms and was built around 1938, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
