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.

AfterTrusted Air Duct Cleaning for Herndon Homeowners
Air duct cleaning in Herndon, VA typically costs $380-$680 for a complete residential system and is performed as a scheduled appointment with a written price agreed before any work begins. At CleanRun Duct Repair & Cleaning, we’ve documented the inside of every duct run we’ve touched since 2013 - over 52,000 homes - and we deliver that photo record to every customer as a standard deliverable, not an upsell. Call (571) 520-6317 for a free estimate with a written price before we start.
Herndon’s housing stock tells a specific story. The town’s rapid growth between 2015 and 2020 filled neighborhoods like Woodland Park, McNair Farms, and the Metropark area with new construction that settled and flexed through freeze-thaw cycles. We’ve found supply registers packed with drywall dust from original construction in homes built during that boom. Older neighborhoods near Historic Downtown Herndon and along Dranesville Road carry decades of accumulated debris - pet dander, pollen from the surrounding Fairfax County tree canopy, and residue from prior HVAC systems. Our crews, operating under Haven Standard Clause 1, arrive with a written price in hand, photograph every duct run before touching it, and leave with a documented record you can review while the truck is still in your driveway.
Tomas Reyes leads CleanRun as an independently owned and operated company, not a franchise. Every technician is background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. The equipment on our trucks includes Rotobrush contact cleaning systems, Nikro negative-pressure extractors, and Abatement Technologies HEPA filtration - brands you can look up yourself before you agree to any price.
What Our Air Duct Cleaning Service Includes
Residential Duct Cleaning
Residential Duct Cleaning covers the complete network of supply and return ducts, plenum (the main distribution box attached to your furnace or air handler), and registers in a single-family home, townhouse, or condo. In Herndon, we typically perform this service for homes between 1,800 and 4,500 square feet, with most jobs falling in the $380-$580 range depending on system complexity and accessibility. Our crew photographs the interior of every duct run before any contact cleaning begins, then delivers those images as part of your standard job record - a practice we’ve held since our first job in 2013.
Commercial Duct Cleaning
Commercial Duct Cleaning addresses the larger-scale HVAC distribution systems found in Herndon’s office parks, retail spaces, and multi-tenant buildings along Van Buren Street, Centreville Road, and near the Dulles Technology Corridor. These systems often feature extended plenum designs, fire dampers, and variable air volume (VAV) boxes that require specialized access and negative-pressure containment to clean without disrupting business operations. We quote commercial work with a written site assessment and price before scheduling, and we coordinate after-hours or weekend service to minimize tenant impact.
Supply Duct Cleaning
Supply duct cleaning targets the pressurized lines that deliver conditioned air from your HVAC unit to each room - the ducts you feel blowing when you hold your hand near a register. In Herndon homes with flex duct runs through hot attics, we’ve documented collapsed or kinked sections that restrict airflow and trap debris; our camera inspection identifies these issues before we quote any repair. The supply side typically accumulates less debris than returns, but it carries whatever the return side collected - making isolated supply cleaning incomplete for most systems.
Return Duct Cleaning
Return Duct Cleaning addresses the larger, unpressurized lines that pull air from your living spaces back to the HVAC unit for reconditioning. These ducts collect the bulk of household debris - skin cells, fabric fibers, cooking particulates, and the fine pollen that penetrates even tight windows during Fairfax County’s heavy spring tree season. We frequently find the first few feet of return trunk heavily loaded in Herndon homes, particularly those with wall-mounted returns near kitchen areas or pet zones. Our Rotobrush contact cleaning system agitates this buildup while Nikro negative-pressure extraction captures it at the source, preventing redistribution through your home.
Full System Cleaning
Full System Cleaning encompasses supply ducts, return ducts, the plenum, registers, grilles, and the accessible surfaces of the air handler cabinet - the complete air distribution path. This is what most Herndon homeowners actually need, and it’s what we recommend when a customer reports uneven temperatures, visible dust emission from registers, or a musty odor when the system cycles. A full system cleaning in Herndon runs $480-$680 for typical homes, with the final written price determined by register count, duct material (sheet metal, fiberglass-lined, or flex), and accessibility factors like crawl space clearance or attic temperature.
Video Inspection
Video inspection uses a flexible borescope camera to record the interior condition of duct runs before we quote any cleaning or repair work. In Herndon, we recommend this when a homeowner suspects a specific problem - a rodent entry, a disconnected joint behind a finished wall, or construction debris from a recent renovation - but cannot locate it visually. The inspection delivers dated, time-stamped footage you receive as part of your documented record. If no cleaning is needed, you pay only for the inspection; if cleaning follows, we apply the inspection fee toward your service price under Haven Standard Clause 1.

Brands We Service for Air Duct Cleaning
We’ve cleaned ductwork connected to every major HVAC brand installed in Northern Virginia over the past two decades. Our crews regularly service systems with Honeywell media air cleaners and Aprilaire whole-house dehumidifiers integrated into the duct network - we know how to remove, clean, and reinstall these components without voiding manufacturer warranties or disrupting calibration. We’ve also worked extensively with Guardsman UV air treatment systems installed in Herndon homes, cleaning the lamp housings and reflective surfaces that degrade when coated with accumulated particulate.
Whether your system carries a brand we’ve named here or any other make - Carrier, Trane, Lennox, Rheem, or a regional installer brand - we can help. Our equipment roster includes adapters and access tools for all common plenum configurations, and our written price covers the full scope before we remove a single panel.
BeforeAfterSigns You Need Air Duct Cleaning Right Now
- Visible dust puffing from registers when the system starts. This indicates debris buildup in the supply ducts near the register, loosened by the initial air surge and pushed into your living space. In Herndon’s older neighborhoods, we’ve traced this to decades of accumulated fine particulate that standard HVAC filters cannot capture.
- Uneven heating or cooling between rooms on the same system. When one bedroom runs ten degrees warmer than another, the cause is often a partially blocked duct run or a collapsed flex section in the attic. Our camera inspection locates the restriction before we quote any work.
- A musty or stale odor when the HVAC cycles on. This typically signals microbial growth on the interior surfaces of fiberglass-lined ducts or standing water in a low point of the system. Herndon’s humid summers create conditions for this, particularly in homes with oversized cooling equipment that short-cycles without adequate dehumidification.
- Increased dust accumulation on furniture within days of cleaning. When your home’s dust load exceeds what the return ducts can transport to the filter, the excess settles on surfaces. We’ve found return duct blockages - collapsed flex, rodent nests, or construction debris - that reduce system airflow by 30% or more.
- You’ve completed renovation or new construction and never cleaned the ducts. Drywall dust, sawdust, and insulation particulate from construction enter ductwork during the build process, even in homes with temporary covers. In Herndon’s 2015-2020 construction boom, we’ve documented substantial debris loads in homes the owners believed were “new and clean.”
Our Air Duct Cleaning Process - Step by Step
- 1
Written price delivered on arrival. Our technician arrives at your Herndon home, identifies themselves by name, and presents a written price for the agreed scope before removing any access panel. This is Haven Standard Clause 1. No work begins without your signature on that document.
- 2
Photo documentation of every duct run. Using a borescope camera, we record the interior condition of each supply and return duct run, the plenum, and the accessible air handler surfaces. You receive these images as part of your standard job record - dated, labeled by location, and stored with your invoice.
- 3
Negative-pressure containment setup. We seal registers and establish suction through a Nikro HEPA-filtered extraction unit, creating negative pressure throughout the duct network. This prevents debris from escaping into your home during the cleaning process, a containment step that distinguishes professional-grade work from coupon-service vacuum noise.
- 4
Contact cleaning and agitation. Our Rotobrush system sends a rotating brush through each duct run, dislodging adhered debris while simultaneous vacuum extraction captures it at the point of release. For sheet metal trunk lines, we use pneumatic whips and skipper balls where appropriate. The technician monitors debris volume and adjusts technique based on what the camera showed in step two.
- 5
Post-cleaning verification and final photo record. We re-camera every cleaned duct run to verify debris removal, photograph the results, and deliver the complete before-and-after record to you before the crew departs. The 365-Day Done Right Promise is activated in writing at this point - if the work is not right, we make it right.
How Much Does Air Duct Cleaning Cost in Herndon?
A typical residential full system cleaning in Herndon runs $380-$680. Here’s how that breaks down by common scenarios:
| Service Scope | Typical Range | What Affects the Price |
|---|---|---|
| Single-system home, 1,500-2,500 sq ft, accessible attic/crawl | $380-$480 | Register count, duct material, debris load |
| Larger home or dual-zone system, 2,500-4,000 sq ft | $480-$580 | Additional plenum, zone dampers, extended trunk lines |
| Complex system with video inspection, repair, or sanitizing | $580-$680+ | Accessibility issues, rodent remediation, UV installation |
Several factors move the price within these ranges. Register count matters - a home with twenty registers requires more time than one with twelve. Duct material affects technique: sheet metal cleans faster than fiberglass-lined, which requires gentler agitation to avoid damaging the interior coating. Accessibility is significant in Herndon, where many homes have flex duct runs through attics that reach 140°F in July; our crews work safely in these conditions, but extended exposure time affects scheduling and labor allocation.
The most important price protection is the written quote itself. Our industry is saturated with $79-$129 coupon offers that become $600+ invoices once the technician is in your home and “discovers” additional vents, mold, or sanitizing needs. CleanRun does not participate in this practice. Our written price covers the full agreed scope - no per-vent add-ons, no surprise charges, no “manager special” pressure. If we find something unexpected during the camera inspection, we stop, show you the image, and quote the additional work separately before proceeding.
Every estimate is free, and we offer a Free Second Opinion on any competitor’s written estimate - bring their quote, and we’ll put our number next to it in writing.

Frequently Asked Questions - Air Duct Cleaning in Herndon
Air duct cleaning is the mechanical removal of accumulated debris from the interior surfaces of your HVAC distribution system, including supply ducts, return ducts, the plenum, and registers. The process removes dust, pollen, pet dander, fabric fibers, cooking particulates, and construction residue - not “toxins” or mysterious contaminants, but the actual material our cameras document inside your ducts. Call (571) 520-6317 for a free estimate - we’ll show you what’s in your system before you decide.
A residential full system cleaning in Herndon takes 3-5 hours for a typical single-system home, depending on register count, accessibility, and debris load. Commercial or complex residential systems may extend to a full day. We schedule with realistic time allocations - our crews do not rush the camera documentation or skip duct runs to meet an artificial deadline. Call (571) 520-6317 to discuss your system’s specific requirements.
Professional full system cleaning in Herndon runs $380-$680 for most homes. Quotes below $200 typically indicate a superficial service - vacuuming registers and the plenum without accessing the full duct network, or a bait-and-switch model where the low price covers minimal work and the technician upsells aggressively on arrival. CleanRun’s written price under Haven Standard Clause 1 covers the complete agreed scope with no additional charges. Call (571) 520-6317 for an exact quote - estimates are free.
Yes. We regularly clean ductwork with integrated Honeywell media air cleaners, Aprilaire dehumidifiers, and Guardsman UV treatment systems, and we know the proper removal and reinstallation procedures for each. Our technicians carry manufacturer documentation for common configurations and will verify compatibility before beginning work. Call (571) 520-6317 to confirm service for your specific equipment.
Air duct cleaning is a scheduled maintenance service, not an emergency response. We do not advertise same-day availability because proper work requires preparation - equipment loading, crew assignment, and review of your system’s specific configuration. For urgent air quality concerns, we can often schedule within 48-72 hours and will prioritize camera inspection to identify any immediate issues. Call (571) 520-6317 to discuss timing.
Every job is backed by the 365-Day Done Right Promise: if the work is not right, we make it right - documented in writing on every invoice, not subject to manager approval or claim denial. This is separate from manufacturer equipment warranties and covers our workmanship specifically. The promise activates at job completion and remains in force for 365 days. Call (571) 520-6317 with any concern during that period.
Clear a path to your HVAC unit, attic access, and crawl space entry if applicable; remove fragile items from surfaces near registers, as vibration during cleaning may cause movement; and ensure pets are secured in a separate area. You do not need to move furniture or cover belongings - our negative-pressure containment and HEPA filtration prevent debris escape. The technician will confirm specific preparations when confirming your appointment window. Call (571) 520-6317 to schedule.
