What it costs
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.

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.
Recent work
What our technicians found and fixed on visits in Alexandria, from their notes on each job.
October 2026
Two systems cleaned, one in the attic and one in the basement, every supply and return. The lining inside the top-floor return was old and torn, so it was flagged for replacement.
October 2026
The camera followed a dryer vent line into the wall and found it had come apart behind the drywall, so the fix means opening the wall.
October 2026
A whole-house air duct cleaning, with prices left for new dryer ductwork and a leaking hose pipe.
What’s different in Alexandria
Inside the City, a lot of what we open is original: sheet-metal runs in the 1950s and 60s houses, and small systems tucked into condo closets from Rosemont to the West End, where more than half the homes are in bigger buildings. On the Fairfax County side it depends on the street. Kingstowne and Franconia are about half townhouses, most from the late 1980s and 90s, while Rose Hill, Mount Vernon and Fort Hunt are mostly single-family houses from the 1960s.
The condo question comes up more here than anywhere else we work. In a condo we clean the unit’s own ductwork and air handler. A riser or a vent run through the building belongs to the association, so we tell you what we see and who to call about it.
The oldest City houses are their own kind of job. Many were built for radiators and got central air later, so the ducts were squeezed into closets, soffits and the attic wherever they’d fit, and in a house still heated by radiators they only run in summer. Getting at them is the hard part, which is one more reason we look before we price.
The oldest streets on the county side are in Belle Haven, where the median house went up in 1957, and Fort Hunt, nearly all single-family houses from the early 1960s. Houses that age usually have a basement with the main trunk running along its ceiling, so the trunk is easy to reach and the long runs out to the far bedrooms are the slow part. Hayfield, mostly late 1970s, sits in between: about two thirds single-family and a third townhouses, and close to nine in ten on gas heat. Huntington is the opposite of all three: mostly condo buildings with small closet systems.
Neighborhood by neighborhood
Census figures for each place, and what that usually means when we open the system. Median year built and heat count owner-occupied homes only.
| Place | Median home built | Most homes are | Heated with | What we usually find |
|---|---|---|---|---|
| City of Alexandria | 1970 | condo and apartment buildings, about 5 in 10 | gas, about 6 in 10 | Condo and apartment buildings: small closet systems and short runs. |
| Rose Hill | 1969 | single-family houses, about 7 in 10 | gas, about 7 in 10 | Houses from before 1980: original sheet metal, and returns built into the floor framing. |
| Franconia | 1986 | townhouses, about 5 in 10 | electricity, about 6 in 10 | Townhouse streets: an air handler in a closet or attic, and a long dryer vent run. |
| Fort Hunt | 1963 | single-family houses, nearly all | gas, about 8 in 10 | Houses from before 1980: original sheet metal, and returns built into the floor framing. |
| Kingstowne | 1994 | townhouses, about 5 in 10 | gas, about 7 in 10 | Townhouse streets: an air handler in a closet or attic, and a long dryer vent run. |
| Woodlawn | 1976 | townhouses, about 4 in 10 | electricity, about 6 in 10 | Houses from before 1980: original sheet metal, and returns built into the floor framing. |
| Lincolnia | 1982 | single-family houses, about 4 in 10 | gas, about 7 in 10 | 1980s and 90s houses: sheet-metal trunks, flexible runs and one big return. |
| Mount Vernon | 1967 | single-family houses, about 7 in 10 | gas, about 7 in 10 | Houses from before 1980: original sheet metal, and returns built into the floor framing. |
By the numbers

When it’s worth doing
About half the homes in Kingstowne and Franconia are townhouses, most from the late 1980s and 90s, with one big return a floor and a dryer vent that climbs a long way to get outside. Thirty years and more of laundry and filter changes is a fair reason to look inside both.
Which is most houses. Nobody opens a duct, so it never comes up until somebody looks.
Drywall dust goes wherever the air goes, and the system was running while they sanded.
The dryer vent, locally
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.

Choosing who cleans them
Questions to ask anybody who quotes you, us included.
Duct cleaning is all inside the house, so the Board of Architectural Review doesn’t come into it. A new vent cap or a moved dryer vent on a wall people can see from the street can, and a company that works in Old Town should tell you before they cut anything.
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.
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.
Ask what it covers: every supply and return, the main trunk, the blower compartment. The $59 mailbox coupon covers getting somebody into the attic.

Where we work

Questions
Yes. We clean the unit’s own ductwork and the air handler or fan coil in the closet, which is usually a quicker job than a house. Anything shared through the building, like a riser or a common vent run, belongs to the association, so we’ll show you what we find and tell you who handles it.
Yes, and most of our Alexandria calls are on the Fairfax County side: Kingstowne, Franconia, Rose Hill, Mount Vernon. Same crew, same prices. The city line changes who issues permits and who supplies your water, not what duct cleaning costs, and duct cleaning doesn’t need a permit anyway.
A condo with its air handler in a closet is a shorter job than a house, often half a day or less. A City rowhouse with ducts run through closets and the attic takes longer, because getting at them is most of the work. You get the time window after the camera photos, before we start.
$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. Dryer vent cleaning is $199 added to a duct cleaning; on its own it’s $199, normally $298, with a year of Comfort+ membership included.
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.
Ready when you are
Call, or send the form at the top. The camera photos come first and cost nothing, including when yours turn out to be fine.
