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.

AfterAir Duct Cleaning Near You in Herndon, VA
If you’re searching for Air Duct Cleaning services near you in the Herndon area, CleanRun Duct Repair & Cleaning serves Herndon and surrounding Fairfax County communities with same-day availability, a written price before any work starts, and a documented photo record of every duct run when the crew leaves. Every call is answered by a live person, and a uniformed, background-checked technician arrives identified by name. There is no “call for a quote” here – you get a written number before a single panel comes off.
CleanRun has operated under the Haven Standard since 2013, completing more than 52,000 jobs across the Washington metro – every one with upfront written pricing and a photo record delivered to the homeowner as a standard job deliverable, not an upsell. Tomas Reyes built this operation on a simple premise: show the customer what’s inside the duct before saying a word about what it costs to fix it.
Fast, Local Air Duct Cleaning
Most Residential Duct Cleaning customers in Herndon who call before noon reach a technician the same day. The service area runs from Herndon’s core neighborhoods – Elden Street, Worldgate, the Fox Mill corridor – outward through Sterling, Reston, Ashburn, Chantilly, Fairfax, Centreville, and McLean. That radius covers the majority of Fairfax County zip codes without a travel surcharge.
Herndon’s housing stock skews toward two-story colonials and townhomes built between 1985 and 2005, most of which run sheet-metal trunk lines with flex-duct branches feeding upstairs registers. After 15 to 20 years, those flex branches collect enough particulate at the saddle fittings to measurably restrict airflow – something the camera confirms before any price is agreed to. Technicians carry Rotobrush and Nikro equipment on every truck, so the right tool is on site regardless of duct configuration. Jobs typically run two to four hours for a standard single-family home.
Areas We Cover
CleanRun’s primary service hub is Herndon, VA, and the team covers a broad corridor of Northern Virginia communities on the same dispatch. If your address falls in Sterling, Reston, Ashburn, Chantilly, Fairfax, Centreville, or McLean, you’re inside the standard coverage zone with no added fee. The team regularly works the Cascades and Countryside neighborhoods in Sterling, the South Lakes and Hunter Mill areas in Reston, Broadlands and Brambleton in Ashburn, the Rocky Run corridor in Centreville, and the Old Town and Franklin Farm sections of Fairfax. Commercial Duct Cleaning calls and McLean residential calls – particularly the older ranch-style homes in Beverly Hills and Langley Forest – come in frequently because the original duct systems in those houses haven’t been cleaned since construction.
For detailed service information specific to Herndon homes, the Air Duct Cleaning in Herndon page covers local pricing ranges, typical duct configurations in the 20170 and 20171 zip codes, and what the camera has found inside Herndon systems over the past decade.
BeforeAfterWhat CleanRun Actually Does on a Job
The process starts with a written scope and a written price – Haven Standard Clause 1 – delivered before any equipment is unloaded. There is no bait-and-switch, no “we’ll tell you the real number once we’re inside.” The price on the paperwork is the price on the invoice.
Once work begins, a technician attaches a Nikro or Rotobrush system to the main trunk line and creates negative-pressure extraction – that’s a continuous vacuum pull through the entire duct system that draws dislodged debris toward a HEPA-filtered collection unit rather than back into your living space. The rotating brush heads used with Rotobrush equipment scrub the interior walls of each duct run; for lined ductwork (common in 1990s Herndon construction), the brushes are adjusted to avoid abrading the fibrous liner. Every run is photographed before cleaning and after, using a camera that captures the plenum, the trunk, and at least one branch per zone. Those photos are handed to the homeowner as part of the standard job record – not stored somewhere on a server, not available “by request.” You get them when the truck leaves.
Herndon’s climate adds a specific wrinkle: the region’s humid summers mean that systems without proper vapor barriers or with undersized return ducts can develop light microbial growth at the A-coil housing and first few feet of supply plenum. If the camera shows it, Tomas Reyes’s technicians document it in writing and explain the options. Air Quality & Sanitizing treatment using Abatement Technologies equipment is available as a separate, separately priced line item – never bundled in without disclosure.
Pricing: What Air Duct Cleaning Costs Near Herndon
Herndon-area pricing for a standard Full System Cleaning job falls within the ranges below. These are written prices – the same figures a CleanRun technician puts on paper before work starts.
| Home Type / Scope | Typical Range |
|---|---|
| Townhome (2 BR/2.5 BA, single system) | $250 – $375 |
| Single-family home (3-4 BR, single system) | $375 – $550 |
| Single-family home (4+ BR, dual-zone system) | $525 – $775 |
| Add: Air Quality & Sanitizing treatment | $95 – $175 per system |
| Add: Dryer Vent Cleaning (same visit) | $89 – $130 |
A few things the $79 coupon companies don’t say on paper: those prices almost always cover a shop-vac pass at the main trunk only, not individual duct runs. The NADCA cleaning standard (ACR 2021) requires negative-pressure extraction across the full system, mechanical agitation of duct walls, and source removal of debris – not a blower pass. CleanRun’s written price covers the full scope. If the camera finds something that changes the scope, the written price is updated and shown to you before any additional work proceeds.
Bring a competitor’s written estimate and CleanRun puts its own number next to it in writing, at no cost. That’s the Free Second Opinion – it exists because a written price comparison is more useful than anything a sales pitch can accomplish.
The 365-Day Done Right Promise
Every CleanRun job – Herndon, Sterling, McLean, everywhere – is backed by the 365-Day Done Right Promise: if the work is not right, CleanRun makes it right. That commitment is written on the job record, not printed in a brochure footnote. It doesn’t require manager approval, a re-inspection fee, or a 30-day window. One year. In writing. On every job.
Tomas Reyes instituted this because the only meaningful guarantee is one you can show to a homeowner in black and white before they agree to anything. The 365-day window reflects confidence in the process – negative-pressure extraction, mechanical agitation, before-and-after documentation, professional-grade equipment – not a marketing calculation.
The H.A.V.E.N. Standard: What It Means in Practice
Every technician who arrives at a Herndon home operates under the H.A.V.E.N. Standard. Haven Standard Clause 3 – Verified Crews – means background-checked, uniformed technicians identified by name before they arrive. The name on the confirmation message is the name on the shirt at the door. License information is published, not buried in a footer. If you want to verify credentials before a technician walks in, that information is available.
Haven Standard Clause 1 covers written upfront pricing – no exceptions, no “we’ll know more once we’re inside” hedging. The written price is delivered before work starts. That’s the whole clause.
Frequently Asked Questions
How fast can you get to my home in Herndon?
Most Herndon calls placed before noon are scheduled same-day. The dispatch hub is positioned to reach Herndon, Sterling, Reston, and Ashburn within a short drive, and the coverage zone doesn’t require routing through DC-area traffic corridors for most calls. If same-day isn’t available, next-morning appointments are standard. Call (571) 520-6317 – a live person answers 24/7 – and they’ll give you a specific arrival window, not a four-hour block.
Do you serve my area if I’m not in Herndon proper?
Yes. CleanRun’s standard coverage zone includes Sterling, Reston, Ashburn, Chantilly, Fairfax, Centreville, and McLean with no travel surcharge. If your address is elsewhere in Fairfax County or Loudoun County, call (571) 520-6317 and confirm the zip code – coverage extends further than the core list in most directions.
How much does air duct cleaning cost near Herndon, VA?
A written price for a standard single-family home in the Herndon area runs $375 to $550 for a single-zone system; dual-zone homes typically run $525 to $775. Those numbers reflect full-system negative-pressure extraction, mechanical agitation, and the documented photo record – not a trunk-only pass. The written price is delivered before any work starts, and it doesn’t change unless the camera finds something materially different from what the scope described, in which case the updated number is shown to you before proceeding. Call (571) 520-6317 for a written estimate specific to your home’s layout.
Can I reach someone after hours or on weekends?
Every call to (571) 520-6317 is answered by a live person, 24 hours a day, seven days a week. Weekend and evening appointments are available for Herndon and surrounding areas. Scheduling, questions about a written estimate, or scope clarification – all of it handled on the call, not routed to a voicemail that returns calls during business hours.
What’s actually included in the job – and what’s not?
The standard job includes: a written price before work starts, full-system negative-pressure extraction, mechanical agitation of every supply and return duct run, a before-and-after photo record of every run delivered to the homeowner, and the 365-Day Done Right Promise in writing. It does not automatically include dryer vent cleaning, air quality and sanitizing treatment, or duct repair and sealing – those are separate line items, separately priced, and only added to the scope with your written agreement. Nothing is bundled in without disclosure.
Why does Herndon have more duct buildup than newer communities?
Most of Herndon’s single-family homes were built between 1985 and 2000, which puts original duct systems at 25 to 40 years of service. The flex-duct branches common in that era – connected to sheet-metal trunk lines with draw-band fittings – accumulate debris at the saddle connection points over time. The region’s humid summers also mean that any duct system running without adequate vapor control can collect light particulate at condensation points near the A-coil. CleanRun’s camera documents exactly what’s present before any price is agreed to.
