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.
What’s different in Haymarket
In the Town of Haymarket most homes went up in the 1980s and 90s, and the median owner home is from 1995. Ductwork from those years is usually a sheet-metal trunk off the air handler with flexible branches to the rooms, and a single large return grille per floor pulling air back. That big grille is where the dust gathers first, and since about a third of the town’s homes are townhouses, the air handler behind it is often in a closet or the attic.
Dominion Valley and Piedmont are the 2000s: across 20169 the median owner home was built in 2006, and about three in four homes are single-family houses. A larger house from that decade often runs two air handlers, one serving the main floors and a second in the attic serving the bedrooms. The attic unit is reached through a ceiling hatch, so it tends to go years without anyone opening it. We clean and price each system separately, and the second is billed for less than the first.
Bull Run Mountain Estates is the older end: a median house from 1978, with oil heat in about four in ten. An oil burner that lights late can puff soot back through the furnace and out into the supply ducts, and it shows as dark streaks around the registers. If that’s what you see, the burner needs an oil heat company’s attention before the ducts do, or a cleaning just gets dirty again.
None of this needs a sign-off. Inside the Town, where the whole town is a historic district, the design guidelines exempt interior work from Architectural Review Board review, and duct cleaning needs no County permit in the town or out of it. If you’d like the dryer line done too, it rides along on the same appointment for $199, and in the town’s townhouses that line tends to run a long way between floors.
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 |
|---|---|---|---|---|
| Bull Run Mountain Estates | 1978 | single-family houses, nearly all | electricity, about 4 in 10 | Houses from before 1980: original sheet metal, and returns built into the floor framing. |
| Haymarket | 1995 | single-family houses, about 6 in 10 | gas, about 6 in 10 | 1980s and 90s houses: sheet-metal trunks, flexible runs and one big return. |
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Inside the town limits only, about one in eighteen of the owner homes with Haymarket mail. Dominion Valley, Piedmont and Bull Run Mountain Estates sit outside it, in the county.

When it’s worth doing
In an oil-heated house, dark streaks on the wall above a register are usually soot from a burner that’s puffing back, not ordinary dust. Get the burner checked by an oil heat company first; the camera photos then show how far into the ducts it went.
A 2005 house has had twenty years of filter changes, some of them missed, and the system may have run while the drywall went up. Nobody has looked inside 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.
The dryer vent, locally
Prince William County Fire and Rescue says to clean the lint out of the dryer vent pipe once a year, to check the venting behind the dryer for damage or restriction, and to have the dryer inspected if clothes take longer than normal to dry or come out hotter than usual. Source.

Choosing who cleans them
Questions to ask anybody who quotes you, us included.
On Bull Run Mountain, dark streaks at the registers can be soot from the burner rather than dust. Ask whether the tech looks for soot first, because cleaning ducts behind a burner that’s still puffing back is paying for the same job twice. On an oil burner that repair is an oil heat company’s; we don’t work on oil.
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.

Jamie and Aaron did a great job replacing our dryer exhaust duct. Showed up on time, worked hard, and cleaned up after everything was done. Impressed with their service.

Questions
Yes. We clean one system at a time, its returns through to its supply runs, and the camera photos cover both of them. The second costs less than the first, and it helps to clear a path to the attic hatch before we arrive.
No. The Town’s Architectural Review Board reviews outside changes the public can see, and its guidelines exempt interior work. Duct cleaning happens indoors, and nothing about it changes the outside of the house.
Usually not. Close to four in ten Town of Haymarket owners heat with electricity, and where a heat pump does the heating, the backup heat strips are mounted in the air handler itself. Summer dust that settled on them burns off once they switch on, and the smell is gone after that. If it returns every time, the camera photos show whether the cabinet and the ducts past it are carrying more dust than they should.
$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.
