Where Vienna’s heat pumps are: a few in the Town, more in Wolf Trap, most toward Tysons.
The Census files a heat pump under electric heat, which makes Vienna a gas town with pockets of heat pumps. Inside the Town about 17 percent of owner homes heat with electricity, roughly 800 houses; in Wolf Trap it’s about 23 percent, close to 1,200, and Dunn Loring runs about the same. In the Tysons Census area, part of which gets Vienna 22182 mail, electric edges past gas at about half.
A Wolf Trap house on electric heat usually has one heat pump outside doing the cooling and the heating, with an air handler and backup strips inside. The typical house there dates from 1980, and a heat pump put in before 2010 most likely holds R-22, unmade since 2020. A leak on one of those usually ends the repair road.
In the gas houses, most of the Town, the heat pump usually goes on the old air conditioner’s pad and the furnace stays. That’s also the one swap Washington Gas, the supplier for most of Fairfax County, pays a dual fuel rebate on: the heat pump has to replace an existing central air conditioner, and the furnace has to meet its efficiency floor. A heat pump traded for a heat pump doesn’t count, so in an all-electric Wolf Trap house the rebate isn’t in play. Our dual fuel guide has the terms.
Toward Tysons, about three in four homes in that Census area are in condo and apartment buildings, and the outdoor half may sit on a roof, a balcony or a shared pad the association controls. Inside the town line, Fairfax County’s permit also needs the Town of Vienna’s approval in its record.
How the houses across Vienna are heated.
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 |
|---|---|---|---|---|
| Wolf Trap | 1980 | single-family houses, nearly all | gas, about 7 in 10 | 1980s and 90s gas houses, most on a second air conditioner, the part a heat pump would replace. |
| Vienna | 1972 | single-family houses, about 8 in 10 | gas, about 8 in 10 | Older gas houses, where a heat pump pairs with the furnace once the ducts are checked. |
Vienna 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.
The Town of Vienna
Nearly the whole town sits in 22180, which it shares with county streets toward Dunn Loring and Merrifield.
- Median home built1972 Census
- Built before 1980about 7 in 10 Census
- Built since 2000about 3 in 10 Census
- Most homes aresingle-family houses, about 8 in 10 Census
- Heated withgas, about 8 in 10 Census
- Rentedabout 2 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 Vienna is worth replacing.
The strips come on during a mild March day
On a Wolf Trap heat pump, backup strips running when it’s 45 degrees out usually mean the outdoor unit isn’t carrying the house, or the thermostat calls them too early. A $99 diagnostic visit tells which before anybody prices a new system.
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 Vienna.
Questions to ask anybody who quotes you, us included.
With gas in the house, did they quote it both ways?
A Vienna house with a sound gas furnace can keep it and add a heat pump outside, or go all electric with a heat pump and air handler. Ask for both prices on one page, with the rebate fit noted beside each.
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.
What our customers say.
I would highly recommend SwiftPro for an HVAC replacement. The sales process was straightforward and fair and the installation was done to my satisfaction in a timely and complete manner (and I’m pretty demanding). Great job!

Heat pump replacement questions from Vienna.
Is a heat pump enough heat for a 1950s Vienna house?
Sized for a winter night, not just a July afternoon, yes, and in most Town houses the gas furnace stays as backup anyway. Where the heat pump is the only heat, as in an all-electric Wolf Trap house, the backup strips cover the coldest hours. Our heat pump winter guide covers what to expect.
I’m in Windover Heights. Can the new outdoor unit go somewhere else?
It can, with a step first. The Town’s Board of Review looks at major exterior changes in the historic district that the street can see, and a replacement on the same pad is the simple case. Moving it into the street’s view is worth raising with the Town first.
How much does heat pump replacement cost in Vienna?
$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.
