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.

AfterVideo Inspection in Fairfax, VA
Duct video inspection is a diagnostic service where a small camera travels through your ductwork and records exactly what is inside – debris accumulation, mold growth, disconnected joints, collapsed sections, or pest activity – before any cleaning or repair work begins. In Fairfax, most homes built between 1975 and 2005 have flex duct runs that degrade over time in ways that are invisible from a register grille. A camera changes that. The inspection takes one to two hours, produces a recorded video and photographic log of every accessible run, and gives you a documented starting point so you know precisely what you are paying to fix.
At CleanRun Duct Repair & Cleaning, video inspection is not an upsell tacked onto a $79 coupon visit. It is the first step we take before quoting any cleaning or repair scope, and every frame captured is delivered to you as part of the standard job record. Tomas Reyes has structured every CleanRun job this way since 2013: the camera goes in first, the written price comes second, and the work starts only after you have seen both. If you have questions or want to schedule an inspection, call us at (571) 526-0015 – a live person answers every call. This service sits within our broader Air Duct Cleaning in Fairfax offering, and the inspection record informs every cleaning and repair decision we make.
When You Need Video Inspection
Some situations make a camera the obvious first call. Others are less obvious but just as important. Here are the scenarios where video inspection pays for itself before a single panel comes off:
- You are buying or have recently bought a Fairfax home built before 2005. Older flex duct systems in neighborhoods like Mantua, Woodson, and Burke Centre deteriorate in ways that look fine from the register but show significant sagging, disconnection, or rodent intrusion on camera. A pre-cleaning inspection establishes a documented baseline so you know what you inherited.
- Musty or earthy odors come from specific registers, not the whole house. Localized odors usually point to a single duct run with standing moisture, biological growth, or a dead pest. The camera identifies the exact location – sometimes it is one short run near a basement slab – so a targeted fix replaces a full-system quote you may not need.
- Your HVAC system is losing airflow in one zone but not others. When the upstairs is consistently warmer or cooler than the thermostat setting, a collapsed flex duct or disconnected joint is frequently the cause. In Fairfax, attic duct runs take significant thermal stress from hot summers and cold winters; that cycling causes failures that only a camera confirms.
- You have visible evidence of pest activity near registers or the air handler. Mice and squirrels enter duct systems through foundation vents and damaged flex connections. Camera footage documents the extent of the intrusion and any nesting material before you spend money on cleaning that would only address part of the problem.
- A previous contractor claimed your ducts needed full replacement but showed you no evidence. We offer a free second opinion on any written estimate. Bring the competitor’s quote; we put our own camera footage and written scope next to it. If the footage shows what they said it shows, we tell you. If it does not, we tell you that too.
- Your home has had recent water damage or a flood event near the air handler or duct runs. Standing water in flex ducts does not evaporate the way it does on hard surfaces. A camera inspection after any flooding event – including the basement flooding that happens in low-lying Fairfax neighborhoods during heavy rain – documents whether remediation is actually needed.
Our Video Inspection Process
The steps below are the same on every job, every time. No variations based on job size or whether we think the ducts look clean from the outside.
- Written scope and price before the panel comes off. Before we open your air handler or cut access points, we deliver a written price for the inspection. That is Haven Standard Clause 1, and it applies without exception. The number you see before we start is the number on the invoice when we leave.
- System mapping and access-point identification. We walk the home with a floor plan or sketch one on-site, identifying every supply and return run, the plenum – the central distribution box connected directly to your air handler – and any branch duct runs that may require separate access points. Fairfax homes with finished basements often have duct runs that were drywalled over during renovations; we map what is accessible and note what is not.
- Camera insertion and full-run recording. We use a flexible inspection camera – sized appropriately for round and rectangular duct profiles – and run it through every accessible duct run from the register end toward the main trunk. The camera records continuously. We note the footage timestamp for any finding: debris accumulation, moisture staining, torn inner liner on flex duct, disconnected joints, biological growth, or foreign material. In a typical Fairfax single-family home, this covers 10 to 20 individual runs depending on the layout.
- Still-frame extraction and annotation. From the recorded footage, we pull still images at each notable finding. Each image is labeled with the duct run, the approximate distance from the register, and a plain-language description of what the image shows: for example, “Supply run 4, approximately 6 feet from register – 2-inch debris accumulation at first elbow, consistent with construction dust not removed at installation.” That language goes into your photo record, not ours.
- Written findings report delivered on-site. Before we pack up, you receive a written findings summary. It lists every run inspected, every finding, and a recommended scope of work – or a clear statement that no work is needed. If cleaning or repair is warranted, the written price for that work is attached. You decide what happens next; we do not start additional work without a separate written authorization.
- Post-work camera verification on any cleaning or repair job. If you authorize cleaning or repair based on the inspection findings, we run the camera again after the work is complete. The before and after footage and photo record are delivered together as your permanent job record. This is the Documented Photo Record included on every CleanRun visit – not a courtesy, a standard deliverable.
BeforeAfterVideo Inspection Pricing in Fairfax
Video duct inspection in Fairfax typically runs between $125 and $275 for a standard single-family home, depending on the number of accessible duct runs, the home’s square footage, and whether any runs require additional access points to be cut and patched. For more details, see our guide on How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - Fairfax, VA. Below is what the range looks like by scope:
| Scope | Typical Range (Fairfax Market) |
|---|---|
| Townhouse or condo, 1 system, up to 10 runs | $125 – $175 |
| Single-family home, 1 system, 10-20 runs | $175 – $225 |
| Single-family home, 2 systems or 20+ runs | $225 – $275 |
| Inspection bundled with full duct cleaning (same visit) | Included in cleaning scope – no separate line item |
Three things move the price within that range. First, duct count: a Fairfax colonial with a finished basement and a second-floor system has more runs than a rancher, and more runs mean more camera time. Second, access difficulty: runs that were drywalled over in a renovation or routed through tight crawl spaces require more time to access safely. Third, whether the inspection is standalone or part of a cleaning scope booked on the same visit – when we are already on-site and set up for Air Duct Cleaning services, the inspection is folded into the cleaning price rather than billed separately.
There is no “call for a quote” here. When you call (571) 526-0015, we ask a few questions about your home’s layout and system count, and we give you a written price range before anyone drives out. The exact written price is confirmed on-site before any access point is opened. That is Haven Standard Clause 1, and it does not have exceptions.
Free estimates are available, and if you have a written estimate from another contractor, we will put our own inspection findings and price next to it in writing at no charge.
What the Camera Actually Shows in Fairfax Homes
This is worth spending a paragraph on, because “duct inspection” can sound like a formality rather than a diagnostic tool. In Fairfax specifically, we see a few patterns that repeat across neighborhoods with enough regularity that they are worth naming.
In homes built between 1978 and 1995 in areas like Fair Oaks, Oakton, and Annandale, original sheet metal trunk lines were often connected to flex duct branch runs with drawband connections – a metal band cinched around a flex duct collar. Over 25 to 30 years, those bands loosen. The camera shows a gap between the flex duct liner and the trunk, sometimes an inch or more wide, where conditioned air has been dumping into the attic or crawl space rather than reaching the register. The fix is straightforward once the camera confirms the location. Without the camera, it looks like an HVAC sizing problem or a zoning problem, and the homeowner ends up spending money on the wrong solution.
In homes built from 1995 to 2010 in parts of South Riding, Centreville, and Chantilly – areas CleanRun serves regularly from Fairfax with Commercial Duct Cleaning expertise – construction-phase debris is a consistent finding. Drywall dust, insulation fragments, and occasionally actual construction waste left inside duct runs during the build phase compresses over time at elbows and damper locations. The camera shows it as a dense, chalky accumulation that a shop-vac approach cannot reach from the register end. Negative-pressure extraction with agitation equipment – Rotobrush or Nikro systems – is what actually removes it, and the post-work camera confirms whether it was removed.
Biological growth – typically a dark surface staining on the interior duct liner – appears in homes where humidifier drain lines were improperly routed or where a supply plenum sits in a humid basement without adequate insulation. The camera identifies the affected runs and the approximate square footage of staining, which is what informs any sanitizing scope. We do not quote sanitizing without camera evidence. That is a straightforward position: we are not going to recommend a service we cannot show you evidence for.
The Documented Photo Record: What You Receive
Every CleanRun inspection produces a physical deliverable – not a verbal summary, not a handshake. Here is exactly what you receive before we leave:
- A written findings report listing every duct run inspected by location and run number, with a plain-language description of each finding or a “no significant finding” notation for runs that are clear.
- Annotated still images from the camera footage, labeled with run location, distance from register, and finding description.
- A written recommended scope of work, if any work is warranted, with a line-item written price attached.
- If cleaning or repair was performed on the same visit: before and after images for every run, delivered together so the difference is documented side by side.
This record is yours. Tomas Reyes put this documentation practice in place when CleanRun served its first job in 2013, and it has been standard on every one of the 52,000+ homes served since. The reason is straightforward: if we are going to tell you that your ductwork needed attention, we should be able to show you exactly what that means in a format you can keep.
FAQs – Video Inspection in Fairfax
How much does duct video inspection cost in Fairfax, VA?
Duct video inspection in Fairfax runs between $125 and $275 for most single-family homes, depending on the number of duct runs and whether any additional access points need to be opened. Townhouses and condos with fewer runs typically land in the $125-$175 range. When inspection is bundled with a Air Duct Cleaning Near Me in Fairfax, VA scope on the same visit, it is included in the cleaning price rather than billed as a separate line. Call (571) 526-0015 and we will give you a written range before scheduling – no guessing.
Do I need a video inspection before duct cleaning, or can I skip it?
A video inspection before cleaning tells you what is actually inside your ducts so the cleaning scope is sized correctly. Without it, a contractor is quoting a flat-rate job without knowing whether your system has two moderately dirty runs or eight runs with compacted debris at every elbow. CleanRun includes camera inspection as part of every full cleaning job, so you are not paying for a separate visit – the inspection informs the scope, and the post-cleaning camera confirms the result. You can also book a standalone inspection if you want a diagnostic record without committing to a cleaning scope at the same time.
Can a camera inspection detect mold in my ductwork?
A camera inspection can identify surface discoloration, staining, and growth patterns on interior duct surfaces that are consistent with biological activity – and can document the location and approximate extent of any visible growth. What a camera cannot do is identify a specific mold species; that requires air sampling or surface sampling sent to a lab. If the camera shows significant staining and the homeowner wants species confirmation, we note that in the written findings and can refer you to an indoor air quality professional for sampling. We do not recommend sanitizing based on a general feeling that ducts might be contaminated; the camera gives you something specific to act on.
How long does a video duct inspection take in a typical Fairfax home?
A full inspection of a single-system Fairfax home with 10 to 15 duct runs takes between 60 and 90 minutes. A two-system home or a home with more than 20 runs runs closer to two to two-and-a-half hours. That time includes the camera run, still-frame extraction, annotation, and the written findings report delivered before we leave. If we find something during the inspection that you want to address the same day, we can often extend the visit to complete cleaning or a minor repair – but that requires a separate written authorization before any additional work starts.
