Arlington / Leesburg
Leesburg has 49,171 residents (give or take 61) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5144984, checked 2026-10-19), about 3,909 people per square mile.
Leesburg is about 29 miles from the Census center point for Arlington in a straight line and covers 12.58 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).
Median household income in Leesburg is $145,205 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5144984, 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.
3,909 people per square mile puts Leesburg in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
43% of Leesburg homes are single-family detached, 2% are in two- to four-unit buildings and 24% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5144984, checked 2026-10-19).
31% of Leesburg homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5144984, checked 2026-10-19), so beside the 43% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Leesburg has 8 points fewer detached houses than Loudoun County overall (51%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US51107, checked 2026-10-19).
Of the 16,660 occupied homes in Leesburg, 58% heat with natural gas, 1% with heating oil, 39% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5144984, checked 2026-10-19).
Gas heats 58% of Leesburg against electricity at 39%, 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.
Leesburg has about the Loudoun County oil share of 2% and 8 points more electric heat than the county's 31% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US51107, checked 2026-10-19).
No electric utility is on file for Leesburg on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Leesburg has 17,155 housing units, 2% built before 1940 and 24% before 1980, with 36% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5144984, checked 2026-10-19).
Leesburg has 21 points fewer homes built after 2000 than the county's 57% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US51107, checked 2026-10-19).
The median Leesburg home was built in 1993 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5144984, checked 2026-10-19) and the median home has 6.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5144984, checked 2026-10-19).

That 12F figure is the Loudoun County cold-day number a Leesburg 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 58% of Leesburg on gas and 39% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Leesburg home has 6.4 rooms and was built around 1993, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
