The AC quit, and you heat with gas
A heat pump can go where the air conditioner sat, heat on mild days and leave the cold nights to the furnace. That’s dual fuel.
A new heat pump and air handler in Falls Church costs $8,499 to $21,650 installed. Over half of Bailey’s Crossroads owners heat with electricity.

Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works
Might it be a repair? The diagnostic visit is $99, and the tech prices the repair and the replacement side by side. Financing is available, subject to approval.
With Comfort+ membership at $199 a year, the diagnostic visit is included, and half of each repair bill is banked toward replacing that system, up to $1,500.
What’s different in Falls Church
The Census files a heat pump under electric heat, and across Falls Church that share swings widely. In Pimmit Hills fewer than 1 in 10 owners heat with electricity; in Lake Barcroft it’s about 2 in 10, in the City and West Falls Church about 3 in 10. Idylwood is around 4 in 10, and Bailey’s Crossroads is the one place here where electric heat is the majority, at 54 percent.
Most of those electric homes are in buildings. More than 6 in 10 Bailey’s Crossroads homes are in buildings of ten units or more, and Seven Corners and Idylwood both sit above 4 in 10. There the heat pump is usually the whole system, an air handler with heat strips in a closet and an outdoor half wherever the building put it, so the new air handler has to clear the closet door and the outdoor unit goes where the association says.
The City of Falls Church makes its own case for heat pumps, on energy pages tied to its goal of net zero carbon emissions by 2050, and it’s frank about the catch in older houses: many have 60 or 100 amp electrical service, and the City recommends 200 amps for most heat pumps. That matters in the City, where a third of homes predate 1960, and in West Falls Church and Lake Barcroft, where close to half do. Inside the City a service heavy-up is a permit the counter issues without plan review, checked at inspection.
In the gas houses, most of Pimmit Hills, Lake Barcroft and West Falls Church, a heat pump usually goes outside in the condenser’s spot and takes over most of the heating, with the gas furnace kept for the coldest stretch. Keeping the furnace also keeps the job off the gas side: inside the City, removing a gas appliance is gas permit work. Our dual fuel guide covers how that pairing runs.
Neighborhood by neighborhood
Census figures for the owner-occupied homes in each place, and what that usually means for a heat pump.
| Place | Median home built | Most homes are | Heated with | What a heat pump job usually looks like |
|---|---|---|---|---|
| West Falls Church | 1957 | single-family houses, about 6 in 10 | gas, about 7 in 10 | Older gas houses, where a heat pump pairs with the furnace once the ducts are checked. |
| Bailey’s Crossroads | 1980 | condo and apartment buildings, about 6 in 10 | electricity, about 5 in 10 | Condo and apartment buildings on electric heat: small heat pumps, the outdoor half on a roof, balcony or pad. |
| Idylwood | 1975 | condo and apartment buildings, about 4 in 10 | gas, about 5 in 10 | Condo and apartment buildings: compact closet systems, and the association decides where an outdoor unit goes. |
| City of Falls Church | 1964 | condo and apartment buildings, about 5 in 10 | gas, about 7 in 10 | Condo and apartment buildings: compact closet systems, and the association decides where an outdoor unit goes. |
| Lake Barcroft | 1958 | single-family houses, about 6 in 10 | gas, about 8 in 10 | Older gas houses, where a heat pump pairs with the furnace once the ducts are checked. |
| Seven Corners | 1972 | condo and apartment buildings, about 5 in 10 | gas, about 6 in 10 | Condo and apartment buildings: compact closet systems, and the association decides where an outdoor unit goes. |
| Pimmit Hills | 1961 | single-family houses, about 7 in 10 | gas, about 9 in 10 | Older gas houses, where a heat pump pairs with the furnace once the ducts are checked. |
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise. A heat pump counts as electric heat.
ZIP 22046, plus a few City addresses in 22042 and 22044.
22041 to 22044: West Falls Church, Idylwood, Lake Barcroft, Seven Corners and Bailey’s Crossroads.
When it’s time
A heat pump can go where the air conditioner sat, heat on mild days and leave the cold nights to the furnace. That’s dual fuel.
The outdoor unit may sit on a roof, a balcony or a shared pad, so the association has a say in where a new one goes. Your condo documents say what’s yours.
It heats all winter and cools all summer, so it piles up hours an air conditioner never sees. Past 15 years, price the replacement beside any big repair.

Choosing who installs it
Questions to ask anybody who quotes you, us included.
If the heat pump is replacing a gas furnace rather than an old heat pump, the panel decides a lot. Ask whether the quote assumes your current service or an upgrade, and if an upgrade, whether it’s priced in writing with everything else.
Copying the old nameplate repeats whatever guess was made when the house was built. The wrong size runs worse in both seasons.
A heat pump system is the outdoor unit plus the air handler inside. Ask whether the quote covers both, matched, in writing.
Set wrong, the electric strips run on mild days. Ask who programs the thermostat and at what outdoor temperature the strips may come on.

Questions
The City of Falls Church says its climate suits most heat pump models. A heat pump heats with a long, steady stream of warm air rather than short hot bursts, so in an older house the City also suggests checking air sealing and insulation first, and sizing should account for what you find.
Not for a single-family house: the City lets an air conditioner or heat pump be replaced without a permit. Changing the electrical service or wiring takes an electrical permit. On the county side, Fairfax County treats the swap as mechanical permit work, with an A2L certification for systems on the newer refrigerants.
$8,499 to $21,650 installed for a heat pump system, the outdoor unit and the air handler, 2 to 5 ton. A small single-stage system lands near the bottom, a big variable-speed one near the top. The HVAC estimator narrows it to your house.
A heat pump system runs $8,499 to $21,650 installed; a gas furnace and air conditioner together, $8,898 to $23,000. No gas line usually means a heat pump. With gas, you can keep the furnace and add one; our heat pump vs gas furnace guide runs the numbers.
