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 Herndon, VA
Duct video inspection is exactly what the name says: a camera goes inside your duct system before any cleaning or repair work begins, and what it finds gets documented in writing. In Herndon, where a significant share of the housing stock dates to the 1980s and early 1990s, that footage regularly turns up debris accumulation, collapsed flex duct sections, and mold-like growth that a technician running a shop vac would never flag – and you would never know to ask about. If you have already gotten a quote from another company and want a second set of eyes on the scope, call us at (571) 520-6317. Written price before any work starts, every time.
Video inspection sits inside our broader Air Duct Cleaning in Herndon service as the diagnostic first step. The camera footage determines the written scope – which runs need agitation, which connections need repair, whether a sanitizing treatment is warranted. No footage means no evidence. No evidence means the scope is a guess.
Since 2013, CleanRun has completed duct inspection and Commercial Duct Cleaning on more than 52,000 homes. Every one of those jobs started with a written price and ended with a documented photo record delivered to the homeowner. That practice is not a selling point we added later. It is how Tomas Reyes set up the first job in 2013 and how every job still runs today.
When You Need Video Inspection
Some situations make inspection optional. These make it the correct starting point.
- You’re buying or have recently bought a Herndon home built before 2000. Duct systems in older Herndon neighborhoods like Chandon, Fox Mill Estates, and Bryson often still carry original flex duct or duct board that has never been inspected. A pre-purchase or first-year inspection gives you a documented baseline before problems compound.
- A previous contractor cleaned your ducts but left no photos. If the technician showed up, made noise, and left without showing you what was inside before and after, you have no record of what was actually done. Video inspection creates that record.
- You’re getting inconsistent airflow between rooms. Weak supply at a register in one room while another runs strong often points to a collapsed duct section or a disconnected joint – conditions that show up immediately on camera and can be quoted for repair on the same visit.
- You’ve seen evidence of pest activity in your home. In Herndon, rodent and insect intrusion into duct systems is more common than most homeowners expect, especially in homes with crawlspace or slab-edge ductwork. Droppings, nesting material, and breach points all appear on the camera feed and are included in the photo record.
- There’s a musty or stale smell that worsens when the HVAC runs. This pattern frequently traces to mold-like growth in a specific duct run, often near a supply plenum – that’s the distribution box where conditioned air first enters the duct system – or at a low point where condensation has pooled. The camera locates it. Guessing does not.
- You want a written baseline before an HVAC system upgrade. Installing a new air handler or heat pump in a duct system with undetected gaps or debris will immediately compromise the new equipment’s efficiency. Inspection before the upgrade documents what the duct system can actually deliver.
Our Video Inspection Process
Every inspection follows the same sequence. The steps do not change based on house size or how long the job is expected to take. Haven Standard Clause 1 applies to the price; the process applies to the work.
- Written price before the panel comes off. Before the technician touches the duct system, you receive a written price for the inspection. That price does not change unless the scope changes, and if the scope changes, the new price is written before any additional work begins. “Call for a quote” does not exist here.
- System walk-through and register count. The technician walks the home, counts every supply and return register, and notes the system configuration – number of zones, location of the air handler, duct material type. Herndon homes vary considerably here: some have all-metal trunk-and-branch systems, others have flex duct throughout, and a number of townhomes in the Worldgate and Herndon Chase areas use a hybrid arrangement that requires a different camera approach at branch points.
- Camera insertion at each duct run. The inspection camera enters at the register opening or the main trunk, depending on system layout. The technician advances the camera through each run, recording continuous footage. Debris depth, visible mold growth, pest evidence, joint separations, liner tears in flex duct, and standing moisture are all documented as the camera moves. We use Rotobrush inspection equipment, which is trade-standard for residential ductwork and capable of navigating the tight radius bends common in two-story Herndon colonial-style homes.
- Return-side and plenum inspection. The return plenum and return duct runs are inspected separately. Return-side contamination is often worse than supply-side because unfiltered air – or air that has bypassed a dirty filter – moves through the return. Debris at the return plenum opening frequently tells the full story of how long it has been since the system was last serviced.
- Findings documented and explained on-site. After the camera work is complete, the technician reviews the footage with you. Not a summary. The actual footage, timestamped, with specific findings called out by location. If the camera showed a 4-inch debris accumulation at the first elbow off the air handler plenum, that is what you see. If a flex duct run has a partial collapse reducing airflow by what the camera confirms is approximately 60% of the duct diameter, that is shown and described in plain language.
- Written scope and written price for any recommended next steps. If the inspection finds conditions that warrant cleaning, repair, or sanitizing, the technician produces a written scope and written price before any follow-on work begins. The photo record from the inspection is included as a standard deliverable regardless of whether you proceed. That record is yours, not ours to hold as leverage.
BeforeAfterVideo Inspection Pricing in Herndon
Duct video inspection in Herndon typically runs between $95 and $195 as a standalone service, depending on system size and duct configuration. Here is what affects where your job lands in that range.
- Number of duct runs: A smaller Herndon townhome with 8-10 registers runs toward the lower end. A 4-bedroom single-family home in Fox Mill or McNair Farms with 18-22 registers runs toward the upper end because camera time per run adds up.
- System configuration: Homes with both a main-floor and upper-floor air handler – common in larger homes in the Centerview and Worldgate corridor – require separate inspection sequences for each system, which affects the total price.
- Duct material: Rigid metal duct moves a camera faster than flex duct, which requires slower advancement to document liner condition accurately. A flex-dominant system adds time.
- Inspection bundled with cleaning: When video inspection is scheduled as part of a full duct cleaning, the inspection cost is rolled into the cleaning price. The two services together for a standard Herndon single-family home run approximately $350-$650 depending on system size, soil level found on camera, and whether any repair or sanitizing is warranted.
The written price is delivered before any work begins – always. If the inspection finds nothing that warrants follow-on service, you receive the photo record and that is where the job ends. There is no pressure to add services that the footage does not justify.

What the Camera Has Found in Herndon Homes
Specific findings carry more weight than general descriptions, so here is what the inspection camera has actually documented across Herndon jobs over the past several years.
In homes near the Herndon Parkway corridor built in the late 1980s, fiberglass duct board lining is a recurring finding. Over decades, the interior surface of duct board can degrade and shed fibers into the airstream. The camera shows this as surface pitting and, in advanced cases, visible liner separation at seams. That condition warrants cleaning and, depending on severity, lining repair or replacement – not a shop vac pass.
In townhomes and condos near the Worldgate area, the camera frequently finds debris concentrations at the first bend after the supply plenum. That elbow is where dust, pet dander, and construction-era debris settle because airflow slows at the turn. A technician who does not run a camera would clean the register face and call it done. The camera shows whether the elbow was actually reached.
In homes with crawlspace ductwork in older parts of Herndon closer to the historic downtown, pest intrusion evidence appears on roughly one in five inspections – not a majority, but frequent enough that camera inspection is not optional for that construction type. Rodent nesting material degrades air quality and, in some cases, carries pathogens. Documenting it on camera is the first step toward a warranted remediation scope.
The Photo Record You Receive
At the end of every inspection, the documented photo record is delivered to you as a standard part of the job. Not on request. Not as an upgrade. Every visit, every time – that practice dates to CleanRun’s first job in 2013 and has not changed.
The record includes still captures from the inspection footage at key points in each duct run: the register entry, the first major bend, any documented debris accumulation, any visible damage to the duct liner or connections, and the return-side findings. If follow-on cleaning is performed, before-and-after captures for each run are included.
The photo record serves a practical function beyond proving the work was done. If you sell the home, it is documentation of the duct system’s condition at a specific date. If a new HVAC contractor claims the ductwork is in poor condition, you have a baseline to compare. If you want to confirm that a future cleaning job actually reached the areas documented in the original inspection, the photos give you a reference point to ask specific questions.
The 365-Day Done Right Promise
Every inspection and cleaning job is backed by the 365-Day Done Right Promise: if the work is not right, CleanRun makes it right. That is a written guarantee included with every job, not a policy subject to manager approval. If the camera footage at a follow-up visit shows conditions that should have been addressed in the original cleaning scope, the issue gets corrected.
Tomas Reyes built that promise into the business from the start because documented evidence works both ways – it protects the customer, and it holds CleanRun accountable to a standard that is visible in the photos, not just stated in marketing copy.
Why Video Inspection Matters More in Herndon Specifically
Herndon’s housing market has a few characteristics that make camera inspection more valuable here than in newer-construction areas.
First, age. A large portion of Herndon’s single-family housing stock was built between 1978 and 1995. That means duct systems that are now between 30 and 48 years old – systems that, in many cases, have never been inspected with a camera and have gone through multiple owners, renovations, and HVAC replacements. Each renovation cycle is an opportunity for duct gaps to open, debris to be introduced, or an original section of ductwork to be orphaned and left connected to nothing.
Second, humidity. Herndon’s mid-Atlantic climate produces humid summers that put consistent moisture stress on duct systems, particularly in homes where the supply-side ductwork runs through unconditioned attic space. The camera finds moisture staining, early-stage biological growth, and insulation displacement in those attic runs at a higher rate than in basement-dominant systems.
Third, the resale market. Herndon is an active real estate market, and homes change hands frequently. Buyers at the price points common in Herndon should know the condition of the duct system they are inheriting. A camera inspection before close – or in the first year of ownership – produces a written record that a seller’s disclosure form does not include.
FAQs – Video Inspection in Herndon
How much does duct video inspection cost in Herndon?
Duct video inspection in Herndon runs $95-$195 as a standalone service, depending on how many duct runs the system has and what duct material is used. Larger single-family homes in Fox Mill or McNair Farms with more than 18 registers run toward the top of that range. When bundled with our Air Duct Cleaning services, the combined price for a standard Herndon home is typically $350-$650. You receive a written price before any work starts – call (571) 520-6317 for your number in writing.
Can you come the same day for a duct inspection in Herndon?
Same-day and next-day appointments are available for most Herndon addresses. All calls are answered by a live person. Call (571) 520-6317 to check availability – the written price is provided before the appointment is confirmed.
What does the camera actually show that a visual check at the register cannot?
A register-level visual check shows approximately the first 6 to 10 inches of a duct run. The inspection camera documents the full length of each run – including the first elbow where debris typically concentrates, mid-run liner condition in flex duct, joint separations that reduce airflow, and the plenum connections that are never visible from a register face. In Herndon homes with older flex duct, partial liner collapses 3 to 4 feet into the run are a common finding that register-level inspection misses entirely.
Do I get to keep the camera footage?
Yes. The documented photo record – still captures from the inspection at key points in each duct run – is delivered to you as a standard deliverable at the end of every job. It is not an add-on and there is no charge for it. If you proceed with cleaning, before-and-after captures for each run are included in the same record. The footage belongs to you from the moment the job is complete.
