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 Dumfries
Inside the Town of Dumfries, homes split almost exactly between single-family houses and townhouses, about four in ten each. That’s two different duct layouts in one small town, and each gets opened and photographed its own way before anyone names a price.
The townhouse rows went up together: Town records date Williamstown to 1974 through 1991, Port O’Dumfries to 1974 through 1988, and South Cove to 1988 through 1992. With about half the Town’s owners heating by electricity, many of those units run a heat pump with the air handler in a closet or the attic, a short trunk, and often a single return grille in the hall pulling air from the whole floor. That grille and the stretch of duct behind it are where the camera goes first.
The single-family streets are older. About four in ten Town homes went up before 1980, and Town records date Whitehaven’s houses from 1930 on and Tripoli Heights from 1950 on. A house that age often had its ducts laid out for a furnace alone, with central air pushed through the same runs years later, and its metal trunk in the basement or crawl space has had decades to collect what the filter missed. The camera photos show that trunk’s joints and low spots before we price it.
Outside the town line the houses get newer. Montclair is about three in four single-family houses with a median built in 1989, and the larger ones there may carry a second system for the upstairs, each its own cleaning. Cherry Hill, covering most of 22026 outside the Town, has a median home built in 2005, about four in ten townhouses, and plenty of flexible duct, which we brush more gently than metal.
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 |
|---|---|---|---|---|
| Montclair | 1989 | single-family houses, about 8 in 10 | electricity, about 5 in 10 | 1980s and 90s houses: sheet-metal trunks, flexible runs and one big return. |
| Cherry Hill | 2005 | townhouses, about 4 in 10 | gas, about 7 in 10 | Townhouse streets: an air handler in a closet or attic, and a long dryer vent run. |
| Dumfries | 1985 | townhouses, about 4 in 10 | electricity, about 5 in 10 | Townhouse streets: an air handler in a closet or attic, and a long dryer vent run. |
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Nearly all of the Town sits in 22026, with a sliver in Triangle’s 22172. None of it is in 22025.
Montclair in 22025, where the Postal Service accepts Montclair as the town name; Southbridge and Cherry Hill in 22026, outside the town line.
ZIPs 22025 and 22026 as a whole: Montclair, Cherry Hill and the rest of Dumfries mail, the Town’s homes included.
When it’s worth doing
In an older Dumfries house with registers in the floor, crumbs, sand and pet hair drop straight into the duct. When the blower starts and the room smells dusty, or you can see debris down the register, that run is due for a look.
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.
In a townhouse with one hall return pulling air from the whole floor, the return duct collects the most. Ask whether the cleaning and the photos cover that return run, not just the registers that blow air out.
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.

Kwon worked hard to clean my air ducts. When he didn’t complete the job the first time due to lack of a high ladder, he came back.

Questions
Yes. Montclair (22025) and Southbridge (22026) both carry Dumfries mail and both sit in Prince William County, outside the Town. The camera photos come first there too, then a written price from the same book we use inside the town line.
No. Cleaning is maintenance. New or replaced ductwork is different: the Town’s mechanical permit has a line for duct work, priced by the zone, so if the photos show a run that needs replacing rather than cleaning, that part goes through Town Hall inside the town line.
No. Each unit in the row has its own system, from the air handler to the last register, so cleaning yours never means opening the house next door. What changes from unit to unit is where the air handler hides, a hall closet, the attic or the lowest floor, so tell us which when you book.
$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
