Thirty-year-old trunk lines and a long heating season: Dunn Loring ductwork.
Dunn Loring’s own ZIP, 22027, covers the east end of the place around Gallows Road, and its typical owner’s house was built in 1991. About half went up between 1980 and 1999, and better than nine in ten are detached. In a house from that stretch the ductwork is usually galvanized trunk lines along the basement ceiling with flexible branches running off to each room. It has been carrying the same air for more than thirty years, and most likely nobody has seen the inside of it.
Heat is what keeps it busy. NOAA’s 1991 to 2020 normals for its Vienna weather station, 3.6 miles west, count 4,931 heating degree days a year against only 964 cooling degree days, and January nights there average about 23 degrees. In roughly seven 22027 homes in ten the heat comes from a gas furnace, so its blower is pulling air back through the returns from late fall well into spring, months longer than the air conditioner runs.
That also tells you when to book. In a typical year that station sees its last freezing night around mid-April and its first around the end of October, and it averages only about thirteen days a year at 90 or above. The weeks on either side of those dates are when the system can sit off for a cleaning and nobody misses it.
About a quarter of 22027 owners heat with electricity, which here usually means a heat pump and an air handler instead of a furnace. Its indoor coil sits right in the air stream, so the photos of the blower compartment matter as much as the ones from the ducts. On the Dunn Loring streets with Vienna mail, west and north of 22027, the houses are mostly from the 1960s and 70s, many with air conditioning added later and returns smaller than the system wants.

The same price book as our air duct cleaning page, for a home up to 2,000 square feet on one system. We look first: the tech takes a cover off, puts a camera in and photographs what’s in your ducts, then shows you, so you see their current condition before you decide. No charge, including when yours are fine. Then you get the price in writing, then we clean.
- Return Air Duct Cleaning$298
- Whole Home Air Duct Cleaning$598, regularly $798
- Whole Home Air Duct Cleaning with ActivePure Air Scrubber$1,798
- Dryer Vent Cleaning, on its own$298

A second system bills at 90 percent of the tier, because it’s isolated and cleaned on its own. The calculator on our air duct cleaning page does the arithmetic for a bigger house.
The dryer vent cleaning is the yearly one, and it’s in Comfort+ membership at $199 a year along with a water heater flush with a sewer camera inspection, a heating maintenance visit and a cooling maintenance visit.
When duct cleaning is worth it in Dunn Loring.
The ceiling was patched after a storm
Wind has brought trees down here before: the June 2012 derecho dropped big limbs across two lanes of Prosperity Avenue. If a limb came through the roof and the drywall was cut and sanded while the system ran, that dust went straight into the returns. The camera photos show whether it’s still there.
You just bought the place
You don’t know whether the last owners had three cats or ever took a register cover off. Most new owners want it done once, early, so they know what they’re starting with.
You’re seeing it at the registers
Grey fuzz on the register face, or dust back on the furniture a day after you wiped it. That’s the one people usually call about.
What the county says about dryer vents.
Fairfax County
Fairfax County Fire and Rescue tells every household to clean the lint out of the dryer vent pipe once a year, sooner if clothes are taking longer to dry, and to have a gas dryer checked by a professional. Source.
How to pick the best duct cleaning company in Dunn Loring.
Questions to ask anybody who quotes you, us included.
On a heat pump, do the photos include the coil?
In a Dunn Loring house heated by a heat pump, the coil in the air handler is where dust stops first. Ask whether the photos include the blower and the coil face, and whether anything the coil needs is priced in writing first.
Do they look before they quote?
Ask whether they’ll put a camera in and show you photos of what’s inside first. A price given at the door, sight unseen, is a price for the average house, not yours.
Do they clean the returns, or only the supply vents?
The returns are the big grilles that pull air back to the system, and they’re the side that collects dust. A job that only counts supply registers leaves half the system alone.
Is the price for the whole system, in writing?
Ask what it covers: every supply and return, the main trunk, the blower compartment. The $59 mailbox coupon covers getting somebody into the attic.

Duct cleaning questions from Dunn Loring.
Is it any different for a Dunn Loring house with Vienna mail?
No. Dunn Loring has no town government, and a 22180 or 22182 envelope changes nothing about a duct cleaning: no permit, same price, $598 for Whole Home Air Duct Cleaning on one system up to 2,000 square feet.
Can the dryer vent be cleaned on the same visit?
Yes, for $199 added to the duct cleaning. In most 22027 houses the dryer vent leaves through a side or back wall, usually a short run.
How much does air duct cleaning cost in Dunn Loring?
$598 for Whole Home Air Duct Cleaning, regularly $798, on a home up to 2,000 square feet with one system, $298 for Return Air Duct Cleaning, and $1,798 with an ActivePure air scrubber installed. A dryer vent is $298 on its own or $199 added to a duct cleaning.
Is it worth it?
Sometimes, and the camera photos are how you find out. If the duct walls are furred over, cleaning takes that out of the loop your air runs through, and the before and after are obvious. If the metal is clean, it isn’t worth doing and we’ll say so. The EPA’s position is that routine cleaning hasn’t been shown to prevent health problems, so we don’t sell it that way.
