Electric heat in a quarter of Annandale, and dual fuel for the gas houses.
In Census terms a heat pump is electric heat, and about a quarter of the owners in 22003 heat with electricity. In the Annandale Census place it’s about 28 in 100 and in Woodburn about 26 in 100, and those two places hold the area’s condo and apartment buildings. In Wakefield, around Canterbury Woods, nearly every home is a single-family house and only about 15 in 100 owners heat with electricity.
In a garden-style condo building near Little River Turnpike and Columbia Pike, or east of Heritage Drive, a heat pump may be the unit’s only heat: an air handler in a closet, the outdoor half on a pad or a roof the association controls. Fairfax County notes that some apartment and condo buildings count as commercial under the building code and need commercial permits, while a house or a townhouse up to three stories goes the residential route.
Gas heats about seven in ten owner homes here, and in each of those a heat pump takes the condenser’s place outside. It carries the cooling and the milder heating days, and the furnace takes over once it gets truly cold. Washington Gas, the gas company for most of Fairfax County, lists a dual fuel rebate for its Virginia customers, but only when a qualifying heat pump replaces an existing central air conditioner; a heat pump swapped for a heat pump doesn’t qualify. Our dual fuel guide works out where gas should take over for a Dominion customer, which most of Annandale is.
A gas house needs one more look: the electrical panel. An all-electric heat pump system carries backup heat strips in its air handler, and those want breaker space a 1960s panel may not have. Dual fuel skips the strips, since the furnace is the backup.

Annandale houses, 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.
Annandale
- Built before 1980about 8 in 10 Census
- Built since 2000about 1 in 10 Census
- Most homes aresingle-family houses, about 5 in 10 Census
- Heated withgas, about 7 in 10 Census
- Rentedabout 3 in 10 Census
- Most houses here burn gas, so a heat pump usually means dual fuel: it replaces the air conditioner and the furnace stays as backup.
- Ducts this old were sized for a furnace’s hotter air. A heat pump moves cooler air, and more of it, so check the ducts before picking a size.

When a heat pump in Annandale is worth replacing.
The AC is near twenty and the furnace has years left
That’s the easy case for a heat pump in a gas house: it takes the old condenser’s spot and the furnace keeps its job. It’s also the swap Washington Gas built its dual fuel rebate around.
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.
It’s past 15 years old
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.

How to pick the best heat pump installer in Annandale.
Questions to ask anybody who quotes you, us included.
Will they check the panel before they price it?
An all-electric heat pump needs a circuit for the outdoor unit and another for its backup strips. Ask if both are in the quote and whether your panel has room, because in a house built around gas heat that isn’t a given.
Did they size it, or copy the old label?
Copying the old nameplate repeats whatever guess was made when the house was built. The wrong size runs worse in both seasons.
Is the air handler in the price?
A heat pump system is the outdoor unit plus the air handler inside. Ask whether the quote covers both, matched, in writing.
Who sets up the backup heat?
Set wrong, the electric strips run on mild days. Ask who programs the thermostat and at what outdoor temperature the strips may come on.

Heat pump replacement questions from Annandale.
Does Washington Gas’s dual fuel rebate apply if I already have a heat pump?
Not under its current Virginia terms: the rebate is for replacing an existing central air conditioner with a qualifying dual fuel heat pump system, and replacing an existing heat pump is excluded. Programs change, so check its page first.
Which is more common in Annandale, a heat pump or a gas furnace?
Gas, by a wide margin: about seven in ten owners against about a quarter on electricity. Compared directly, a heat pump with its air handler is $8,499 to $21,650 installed, against $8,898 to $23,000 for a gas furnace with an air conditioner. The HVAC estimator prices either one for your house.
How much does heat pump replacement cost in Annandale?
$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.
Should I get a heat pump, or a furnace and air conditioner?
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.
