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 Fairfax, from their notes on each job.
October 2026
Return Air Duct Cleaning and a dryer vent cleaning, with a note that the system had no water safety switch and needs one.
August 2026
Air duct cleaning with the grilles brushed or washed and new screws in the registers. The filter was a size too big and held its door open, so the right size was written down.
January 2026
A new return box built and every duct cleaned. The washer and dryer were stacked, so the dryer vent was cleaned from outside, which took a second technician and a 24 foot ladder.
What’s different in Fairfax
The City of Fairfax and Mantua are mostly single-family houses from the 1960s, with sheet-metal ducts and returns that are often just panels across the floor joists. Kings Park West runs to 1970s houses and townhouses. Fair Lakes and Fair Oaks went up in the 1990s, and a lot of Fair Oaks is in apartment and condo buildings, where the system is small and the job goes quicker.
So the first question on a Fairfax call isn’t the price, it’s which of those houses you’re in. A 1965 rambler in Mantua and a 1997 townhouse in Fair Lakes are different jobs, and the camera tells us which one before you pay for anything. Merrifield adds a fourth kind: more than half of it built since 2000, mostly condo and apartment buildings with compact systems.
Heating is a bigger share of what we do in Fairfax than in most towns, and the first cold week is when people notice their ducts: the furnace fires for the first time since spring, and the smell in the first ten minutes is whatever has been sitting in the system. If it fades by lunch, it was dust burning off; if the registers still blow grey a week later, that’s when the camera earns its keep.
Kings Park West stands apart on the county side: 1970s houses and townhouses, and close to half of them heat with electricity. A heat pump runs its blower for longer stretches in winter than a gas furnace does, so the filter and the ducts in those houses move more air, and more dust, over a year. Check the filter a month after you change it; in a Kings Park West heat pump house, one that’s grey that soon is the first sign the ducts deserve a look.
Before you book
The whole system goes under negative pressure from a high-powered vacuum, then brushes and air whips work through every supply and return line, the trunk lines and each branch, so the dust leaves the house instead of landing in your living room. The register and grille faces come off and get washed. You see camera photos of what’s inside before we start, and before and after shots when we can get a clear one.
$598 for a Whole Home Air Duct Cleaning, regularly $798, on a home up to 2,000 square feet with one system, priced by the system and in writing. A whole-house coupon for a fraction of that can’t pay for a crew, the equipment and most of a day, so the number climbs once somebody is in the attic, or two registers get a shop vac. Pulling the blower wheel and cleaning it blade by blade is a separate job, not part of the Whole Home price; if the camera shows yours needs it, you get that price first.
Dust puffing out of the registers when the system starts, or a mat of it inside a supply duct when you pull a grille. Drywall or renovation dust that went through the system while the work was going on. Droppings or insect debris in the ducts. Or you just bought the house and have no idea what the last owners left in it, which in a 1960s Mantua or City of Fairfax house with joist-bay returns can be a lot.
If the camera shows clean metal and nobody in the house is bothered, a cleaning on a schedule isn’t needed, and the EPA says as much. Dust on the furniture by itself is usually a filter question, and a better filter costs far less than a cleaning. When yours don’t need it, that’s what you hear from us.

When it’s worth doing
In plenty of 1960s Fairfax houses the return isn’t a duct at all: it’s the space between two floor joists with a panel nailed across the bottom. Sixty years of whatever fell through the grille ends up in there, and it’s the first place the camera goes.
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.
A 1990s house in Fair Lakes that’s had its filter changed on schedule can look fine on camera. If yours does, the right answer is to change the filter and check again in a few years, and that’s what a good company tells you.
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.

I would gladly recommend them to anyone in the greater Fairfax/Alexandria area without reservation.
Swiftpro came out the same day I called when my AC was out and had it fixed in less than an hour after arriving.
Aaron is great ! He explained to me about how they clean the dryer vent, he replaced my old one with a flex type vent duct, he showed me the camera he used to see into the dryer vent. Very professional answered all my questions . Definitely 10 out of 10.
Questions
Yes, mostly in where the dust collects. A 1960s house has longer sheet-metal trunks and those joist-bay returns, and the heaviest dust is usually on the return side. A 1990s townhouse in Fair Lakes runs mostly flexible duct off one big return, which takes a softer brush and less time. Either way the photos come before the price.
Yes. Inside the city line and all the Fairfax County streets with a Fairfax address, from Mantua and Kings Park West to Fair Lakes and Fair Oaks. Same crew, same prices. Duct cleaning needs no permit on either side of the line, so the City or County question that matters for a furnace swap never comes up.
Yes. Most units in Fair Oaks and Merrifield have one compact air handler in a closet feeding a handful of short runs, which makes for a quicker visit than a house. Check one thing with the association before booking: a dryer vent that climbs through the building, instead of going straight out your own wall, may be theirs to clean.
There’s no set schedule. NADCA, the duct cleaning industry’s standards body, says to inspect and clean as needed, commonly every three to five years, but the real trigger is what the camera shows: dust you can see, renovation dust or pests. A Fair Lakes townhouse with its filters changed on time can go a long while.
A Return Air Duct Cleaning is a couple of hours. A Whole Home Air Duct Cleaning on one system is most of a day, and longer on a big house or with a second system. A whole house promised in under an hour isn’t a duct cleaning.
We won’t promise that. The EPA says research hasn’t shown that duct cleaning by itself prevents health problems. What a cleaning does is take settled dust and debris out of the path your air travels, and with a good filter that’s one part of the answer, not a cure.
$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.
