Heat pump installation in Tysons, VA - rebates, sizing and local data

Tysons in numbers

Tysons has 28,936 residents (give or take 1,835) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5179950, checked 2026-10-19), about 6,785 people per square mile.

Tysons is about 7 miles from the Census center point for Arlington in a straight line and covers 4.265 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 Tysons is $129,818 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5179950, 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.

6,785 people per square mile puts Tysons in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.

Multi-family first

9% of Tysons homes are single-family detached, 4% are in two- to four-unit buildings and 78% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5179950, checked 2026-10-19).

With 78% of Tysons homes in buildings of five or more units and 9% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 66% of Tysons homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5179950, checked 2026-10-19), the landlord signs the quote in many of them.

Tysons has 37 points fewer detached houses than Fairfax County overall (46%) and 49 points more five-plus-unit buildings than the county's 29% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US51059, checked 2026-10-19).

With 66% of Tysons homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5179950, checked 2026-10-19), most heat pump quotes here are landlord-driven: the landlord signs the contract and picks the equipment, and the tenant sees the lower bill.

Heating fuel in Tysons

Of the 14,347 occupied homes in Tysons, 35% heat with natural gas, 0% with heating oil, 62% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5179950, checked 2026-10-19).

Electricity already heats 62% of Tysons homes, ahead of gas at 35%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.

Tysons has about the Fairfax County oil share of 1% and 20 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).

Age of the stock

Tysons has 15,436 housing units, 1% built before 1940 and 26% before 1980, with 41% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5179950, checked 2026-10-19).

Tysons has 21 points more homes built after 2000 than the county's 20% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US51059, checked 2026-10-19).

The median Tysons home was built in 1995 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5179950, checked 2026-10-19) and the median home has 3.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5179950, checked 2026-10-19).

41% of Tysons housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5179950, 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.

Sizing for Fairfax County

Heating design temperature: 14F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Fairfax County 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 Fairfax County cold-day number a Tysons 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.

Next step

Ask for the heat-loss calculation room by room; the median Tysons home has 3.8 rooms and was built around 1995, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
