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.

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.

What’s different in Sterling
Sterling’s oldest streets are around Sterling Park, south of Route 7, and in Sugarland Run just north of it: about four in ten homes in each went up before 1980. Countryside is about eight in ten 1980s and 90s houses. Cascades and Lowes Island came after, their median homes both from 1996, and most of the condos around Dulles Town Center were built after 2000.
Those waves show the moment a register comes off. A Sterling Park house from the 1970s usually still has its first sheet metal, and after fifty years and a few owners the ductwork has often been patched around a moved wall or an addition. A 1990s house in Cascades or Lowes Island tends to have a metal trunk in the basement with flexible runs off it, and the bigger ones often add a second system in the attic for the bedrooms.
How the house heats matters too. In Sterling proper, south of Route 7, just over half the owner homes run on electric heat, and in Countryside nearly eight in ten do, most of them with heat pumps, whose air handlers keep air moving through the ducts for hours at a stretch all winter. Cascades is the opposite, about eight in ten on gas. The cleaning is the same, but a heat pump house leans harder on its filter, so the filter rack and the return grille are where we start.
Dulles Town Center is a different Sterling again. More than half its homes are in condo and apartment buildings, and seven in ten are rented. Those are small systems in a closet with short runs, and the easy time to clean one is when a lease ends, so the owner sees the camera photos with nobody’s furniture in the way.
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 |
|---|---|---|---|---|
| Sterling | 1979 | single-family houses, about 5 in 10 | electricity, about 5 in 10 | Houses from before 1980: original sheet metal, and returns built into the floor framing. |
| Lowes Island | 1996 | single-family houses, about 6 in 10 | gas, about 7 in 10 | Townhouse streets: an air handler in a closet or attic, and a long dryer vent run. |
| Cascades | 1996 | townhouses, about 4 in 10 | gas, about 8 in 10 | 1980s and 90s houses: sheet-metal trunks, flexible runs and one big return. |
| Sugarland Run | 1983 | single-family houses, about 6 in 10 | gas, about 5 in 10 | 1980s and 90s houses: sheet-metal trunks, flexible runs and one big return. |
| Dulles Town Center | 1998 | condo and apartment buildings, about 5 in 10 | gas, about 9 in 10 | Condo and apartment buildings: small closet systems and short runs. |
| Arcola | 2017 | townhouses, about 5 in 10 | gas, about 8 in 10 | Townhouse streets: an air handler in a closet or attic, and a long dryer vent run. |
| Oak Grove | 2005 | townhouses, about 8 in 10 | gas, about 9 in 10 | Townhouse streets: an air handler in a closet or attic, and a long dryer vent run. |
By the numbers

When it’s worth doing
Houses from the 1970s and 80s, a big share of Sterling, often got their lower level finished years after they were built. If the system ran while the drywall was sanded, the dust went where the returns pulled it, and nobody has been in there since.
In a townhouse the vent usually runs a long way to the roof or the back wall. When clothes stop drying in one cycle, that line is the first thing to check, and it’s the one with a fire risk behind it.
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.
The dryer vent, locally
Ashburn Volunteer Fire and Rescue, one of the companies in Loudoun County’s fire and rescue system, says the dryer vent, from the back of the dryer to the outside of the house, should be cleaned at least once a year, and that longer drying times are a sign it’s clogged. Source.

Choosing who cleans them
Questions to ask anybody who quotes you, us included.
Cleaning the ducts means opening the air handler, and in a heat pump house that cabinet holds the coil, the blower and the backup heat strips. An HVAC tech puts it back the way it came apart, and can tell you whether the coil needs attention while it’s open.
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.

Moises and SwiftPro were excellent. They cleaned my dryer duct and repaired an area that had become disconnected and was therefore posing a fire hazard. Moises was punctual, friendly, and even went the extra mile to help me briefly with another small household project.

Questions
Yes. Sterling Park and the rest of the streets south of Route 7, and Sugarland Run, Countryside, Cascades, Lowes Island and Potomac Falls to the north, plus the condos around Dulles Town Center. Same crew and the same price book, and cleaning needs no permit.
Often. Some of the returns in a house that age aren’t ducts at all, just the space between two joists or two studs with a panel nailed over it, and they gather whatever drops in. Runs that got boxed in during a remodel are harder to reach. The camera photos show which runs need the work before you pay for anything.
Usually it’s dust on the backup heat strips in the air handler, burning off the first time they come on for the season. A smell that fades the same day is normal. One that lingers, or comes back every time the strips kick in, is worth a look, and a dusty system gives them more to burn.
$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.
