Arlington / Manassas Park
Manassas Park has 16,798 residents (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5148968, checked 2026-10-19), about 5,537 people per square mile.
Manassas Park is about 20 miles from the Census center point for Arlington in a straight line and covers 3.034 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 Manassas Park is $103,250 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5148968, 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.
5,537 people per square mile puts Manassas Park in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
40% of Manassas Park homes are single-family detached, 7% are in two- to four-unit buildings and 21% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5148968, checked 2026-10-19).
34% of Manassas Park homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5148968, checked 2026-10-19), so beside the 40% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Of the 5,193 occupied homes in Manassas Park, 68% heat with natural gas, 1% with heating oil, 29% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5148968, checked 2026-10-19).
Gas heats 68% of Manassas Park against electricity at 29%, 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.
Manassas Park has about the Manassas Park city oil share of 1% and the same 29% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US51685, checked 2026-10-19).
No electric utility is on file for Manassas Park on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Manassas Park has 5,569 housing units, 0% built before 1940 and 25% before 1980, with 43% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5148968, checked 2026-10-19).
Manassas Park tracks Manassas Park city on housing age, with the county at 0% pre-1940 and 43% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US51685, checked 2026-10-19).
The median Manassas Park home was built in 1997 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5148968, checked 2026-10-19) and the median home has 5.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5148968, checked 2026-10-19).
43% of Manassas Park housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5148968, checked 2026-10-19), and homes that recent usually meet the insulation codes in place at the time, so a heat pump sized to the floor plan lands closer to the real load than it would in an older neighborhood.
Heating design temperature: 14F.

That 14F figure is the Manassas Park city cold-day number a Manassas Park 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 whether the quote is whole-home or partial-home, because with 68% of Manassas Park on gas and 29% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Manassas Park home has 5.5 rooms and was built around 1997, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
