Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

What Residential Duct Cleaning Actually Involves
The term gets used loosely in this industry, so it’s worth being specific. Residential duct cleaning means accessing and mechanically agitating every supply and return duct run in your home’s forced-air system, capturing dislodged particulate under negative pressure using a collection unit connected to the main trunk line, and cleaning the air handler cabinet, blower wheel, and accessible coil surfaces. A shop vac run through two registers is not duct cleaning. Neither is a “system inspection” that ends with an upsell.
At CleanRun, we use Rotobrush rotary brush systems to mechanically break debris from duct walls – not just blow it toward a filter – paired with Abatement Technologies negative-pressure extraction units that keep dislodged material from recirculating into your living space during the process. Every duct run is photographed with a camera before work starts and again after it’s finished. You see both images. That’s the standard – not an upgrade.
The full scope falls under our parent Air Duct Cleaning service, which also covers commercial systems and post-construction cleanouts. The residential page you’re reading right now addresses single-family homes, townhomes, and condominiums with ducted forced-air HVAC in Alexandria and the surrounding neighborhoods.
When You Need Residential Duct Cleaning

There’s no universal rule that says ducts must be cleaned every three years. The National Air Duct Cleaners Association (NADCA) recommends cleaning when one or more of the following conditions exist – and in Alexandria’s older residential stock, several of these tend to show up together.
- Visible debris at the registers. If you pull a supply register off the wall and find a grey-brown mat of dust, pet hair, and particulate packed against the grille, that’s not surface dust – it’s material that has been recirculating through the system long enough to pack in. In Del Ray and Rosemont, where a lot of homes were built in the 1940s through 1960s, original ductwork that has never been cleaned can hold decades of accumulated debris by the time the current owner buys the house.
- Recent renovation or construction. Drywall dust is fine enough to pass through most filters and dense enough to coat duct walls in a single project. If a bathroom, kitchen, or addition was renovated with the HVAC running – or even with vents only loosely covered – the duct system likely needs attention before the next heating or cooling season.
- Allergy or asthma symptoms that worsen indoors. This one requires an honest caveat: duct cleaning is not a medical treatment, and CleanRun won’t tell you it cures anything. What we can say is that when camera inspection reveals mold spores, rodent dander, or accumulated biological material inside the ductwork, removing it tends to reduce the load your HVAC is circulating. If you’re in a home with a crawl space – common in the Waynewood and Hollin Hills areas near the Potomac – moisture intrusion into flex duct is a frequent source of microbial growth.
- Unexplained increase in energy bills. A blower wheel caked in grease and lint has to work harder to move the same volume of air. When the camera shows more than a quarter-inch of coating on blower wheel blades – which we see regularly in Alexandria homes where cooking grease and pet dander have been circulating for years – cleaning it restores airflow efficiency measurably. We don’t put a percentage on that claim because it varies by system, but the before and after photos tell the story clearly.
- You’re moving into a home and have no service history. A surprising number of Alexandria home purchases – especially in the Seminary Hill and Beverley Hills neighborhoods, where the housing stock turns over at higher price points – come with no documentation of any prior duct cleaning. If the previous owner can’t provide a written record with before-and-after photos, the honest assumption is that it hasn’t been done.
- Rodent or insect intrusion. Alexandria’s older neighborhoods have established wildlife. When a squirrel or mouse gets into a duct system – which happens more often than homeowners expect in homes with original galvanized steel duct sections and gaps at joints – the contamination isn’t just the nesting material. It’s dander, urine particulate, and insulation debris that gets distributed through every room every time the system runs. This is one situation where we recommend sanitizing after cleaning, not as an upsell, but because the camera will show you exactly why.
Before
AfterOur Residential Duct Cleaning Process
Here is exactly what happens from the time our crew arrives at your Alexandria address to the time they leave. No steps are skipped based on job size.
- Pre-job camera inspection and written scope. Before any equipment is set up, we run a camera through the accessible duct runs and photograph what’s inside. This takes 20 to 30 minutes and produces the “before” images that become part of your job record. The written price – confirmed before work started under Haven Standard Clause 1 – is on paper before the first panel comes off. If the camera finds something that changes the scope (unexpected mold, animal intrusion, damaged duct sections), we show you the image and give you an updated written number. You decide whether to proceed.
- System isolation and negative-pressure setup. We connect an Abatement Technologies negative-pressure collection unit to your main trunk line – the large central duct that branches to every supply run. This creates a controlled draw through the system so that when debris is dislodged, it moves toward the collection unit rather than back into your living space. Every supply register is temporarily sealed during this phase.
- Mechanical agitation of every duct run. Working from each register opening toward the trunk, a Rotobrush rotary brush system agitates debris from the duct walls. Brush size is matched to duct diameter – typically 4-inch to 14-inch in Alexandria residential systems. Flex duct, which is common in homes built after the 1980s in areas like Cameron Station and Kingstowne, requires a softer brush and slower passes to avoid tearing the inner liner. We note duct material type in the job record.
- Air handler, blower wheel, and accessible coil cleaning. The supply and return runs are only part of the system. The air handler cabinet is opened, the blower wheel is cleaned of grease and particulate accumulation, and the accessible faces of the evaporator coil are cleaned with a coil-safe solution. This is included in the standard residential scope – not a line-item add-on.
- Post-cleaning camera inspection and photo record. After every run is cleaned, we re-run the camera and photograph the same sections that were photographed before work started. You receive both sets of images as part of the standard job deliverable. If a duct run doesn’t look materially different in the after photo, we go back and run the brush again. The photo record is how we hold ourselves accountable – and how you can verify the work without taking our word for it.
- Written summary and 365-Day Done Right Promise. Before the crew leaves, you receive a written summary of what was found, what was done, and the condition of each duct section documented during the visit. The 365-Day Done Right Promise is written into the job record at this stage: if anything about the cleaning isn’t right within a year, we make it right. Not subject to manager approval – it’s in writing on the job summary.
Residential Duct Cleaning Pricing in Alexandria

Residential duct cleaning in Alexandria costs between $280 and $650 for most single-family homes. Here is what drives the difference, and what that number actually includes.
| Home Type / Scope | Typical Price Range |
|---|---|
| Condo or small townhome (up to 8 registers) | $280 – $380 |
| Single-family home, 1,500 – 2,500 sq ft (up to 16 registers) | $380 – $520 |
| Larger single-family home, 2,500 – 4,000 sq ft (up to 25+ registers) | $520 – $650 |
| Sanitizing treatment (after mold, rodent, or renovation contamination) | $95 – $180 added to base scope |
| Air handler and blower wheel cleaning | Included in all residential scopes |
| Documented Photo Record (before and after) | Included in all residential scopes |
The number on your written quote is the number on your invoice. Haven Standard Clause 1 doesn’t allow for “we’ll know more once we open the system” pricing structures. If the camera inspection before work starts reveals a condition that changes the scope, you get a new written number and the choice to proceed or not.
Alexandria has a meaningful number of homes with original 1950s and 1960s galvanized steel ductwork – particularly in Rosemont, Del Ray, and the streets immediately around Episcopal High School. These systems often have three to four decades of debris packed into duct interiors that are narrower than modern standards, which can add time and place the job at the higher end of the range. We’ll tell you that before we start.

FAQs – Residential Duct Cleaning in Alexandria
How long does residential duct cleaning take in Alexandria?
Most residential duct cleaning jobs in Alexandria take three to five hours for a single-family home, depending on register count, duct material, and the level of debris accumulation. Condominiums and smaller townhomes typically run two to three hours. The pre-job camera inspection adds 20 to 30 minutes to the front end, and post-job documentation adds another 15 to 20 minutes at the close. We don’t quote a time and then rush through it – the Documented Photo Record at the end keeps the crew honest about whether every run was actually cleaned. Call (240) 318-7712 for a written estimate that includes an expected time window for your specific home.
Is duct cleaning worth it for Alexandria homes built before 1980?
Pre-1980 Alexandria homes – particularly the brick colonials in Seminary Hill, the Cape Cods in Beverly Hills, and the ramblers throughout Rosemont – often have original galvanized steel ductwork that has never been mechanically cleaned. When the camera goes into these systems, it’s common to find debris accumulation measured in inches, not a light coating. Whether cleaning is worth it depends on what the camera actually shows, which is why we photograph before we quote a final scope. A Free Second Opinion is available if you’ve already received a written estimate from another company. Call (240) 318-7712.
What’s the difference between duct cleaning and duct sanitizing?
Duct cleaning removes the physical debris – dust, lint, particulate, accumulated biological material – through mechanical agitation and negative-pressure extraction. Sanitizing applies a solution to duct surfaces after cleaning to address microbial residue: mold spores, bacteria, and similar contaminants that mechanical cleaning alone doesn’t neutralize. We recommend sanitizing when the pre-job camera inspection shows evidence of mold growth, moisture damage, or rodent intrusion – not as a default upsell. In Alexandria homes with crawl-space HVAC runs or older flex duct near basement slab edges, moisture intrusion that creates mold conditions is something we document with the camera before recommending the additional step. Sanitizing adds $95 to $180 to the base scope, depending on system size.
How do I know the cleaning was actually done and not just a vacuum at the registers?
The Documented Photo Record answers this directly. Before any work starts, we run a camera through the accessible duct runs and photograph what’s inside. After cleaning, we photograph the same sections again. You receive both sets of images as a standard part of the job record – not on request, not as an upgrade. The before and after images from a Rotobrush mechanical cleaning look materially different from a shop-vac pass at the register face. If the after photos don’t show a clean duct wall, we go back and clean it again. The 365-Day Done Right Promise is in writing on your job summary, which means the accountability doesn’t end when the truck leaves.
