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 Fairfax Homeowners
Air duct cleaning in Fairfax, VA typically costs $380-$780 for a complete residential system and produces a measurable improvement in airflow and airborne dust load. Since 2013, CleanRun Duct Repair & Cleaning has served more than 52,000 homes with a written price delivered before any work begins and a documented photo record of every duct run included as standard. Our crews work throughout Fairfax County neighborhoods from Fairfax city proper to the outlying subdivisions near Burke Lake and along Route 50.
Fairfax presents specific challenges for ductwork: the clay-heavy soils of Northern Virginia shift seasonally, stressing sealed duct connections in slab and crawl-space homes common to the 22030, 22031, and 22033 zip codes. Older colonials near the historic district and the 1980s-2000s builds in Penderbrook and Fair Lakes often show accumulation patterns tied to original construction debris and decades of HVAC runtime without cleaning. We photograph what we find, name it in plain language, and put the scope and price in writing before a panel comes off. Call (571) 526-0015 for a free estimate.
What Our Air Duct Cleaning Service Includes
Residential Duct Cleaning
Residential Duct Cleaning covers the complete network of supply and return runs, plenum (the central distribution box), and accessible trunk lines in single-family homes, townhouses, and condominiums. Fairfax’s housing stock varies widely, from 1960s ranches near Woodson High School to new construction in Mosaic District, and each presents different access points and contamination profiles. We use negative-pressure extraction, which means a powerful vacuum maintains suction on the entire system while mechanical brushes dislodge debris, preventing redistribution into living spaces. Every residential job includes a written scope, a fixed price under Haven Standard Clause 1, and before-and-after photography inside every duct run we access.
Commercial Duct Cleaning
Commercial Duct Cleaning addresses the larger-scale HVAC distribution systems found in Fairfax office parks, retail spaces, medical suites, and multi-tenant buildings along corridors like Westpark Drive and Fair Lakes Parkway. These systems typically use sheet-metal trunk lines with flexible duct branches, and they accumulate construction dust, paper fiber, and biological loading at different rates than residential systems. CleanRun crews scale equipment accordingly, using Nikro and Abatement Technologies industrial vacuums with HEPA filtration rated for commercial airflow volumes. We work with property managers to schedule around tenant hours, document compliance for insurance or lease requirements, and deliver the same written price guarantee and photo record as our residential jobs.
Supply Duct Cleaning
Supply ducts carry conditioned air from your HVAC unit to each room, and they are the lines most visibly connected to your floor, wall, or ceiling registers. In Fairfax homes, we frequently find supply runs clogged with fine sediment from original construction, particularly in neighborhoods like Kings Park and Mantua where homes sat through multiple drywall and flooring phases before final duct sealing. Our crews remove each register, insert a camera to assess loading, then use Rotobrush mechanical agitation combined with negative-pressure extraction to remove buildup without damaging flexible duct liner. The photo record shows you exactly what left the system and what remains.
Return Duct Cleaning
Return ducts pull air back to the HVAC unit for reconditioning, and because they are open to common spaces, they collect the most visible debris: pet hair, cooking particulate, and general household dust. In Fairfax’s older homes near the courthouse, return pathways are sometimes built into wall cavities or floor joist channels rather than dedicated ductwork, requiring adapted access methods. We inspect with a borescope (a flexible camera), seal temporary access points when needed, and clean using appropriate tools for the construction type. Return Duct Cleaning often produces the most dramatic before-and-after photos because the loading is typically heaviest at the grille and first elbow.
Full System Cleaning
Full System Cleaning encompasses supply ducts, return ducts, the plenum, trunk lines, and the accessible surfaces of the air handler cabinet, including the blower assembly and evaporator coil housing. This is the service most Fairfax homeowners need when they have never had duct cleaning performed, or when moving into a previously owned home without maintenance records. We price full system cleaning as one flat rate per system under Haven Standard Clause 1, not per vent or per hour, so the written quote matches the final invoice. The job concludes with a complete photo record, typically 15-30 images depending on system complexity, delivered as part of your standard documentation.
Video Inspection
Video inspection uses a borescope or duct-mounted camera to document the interior condition of your ductwork without disassembly, useful for identifying blockages, disconnected runs, or contamination severity before committing to full cleaning. In Fairfax, we recommend video inspection for homes with persistent odors, uneven heating or cooling, or recent rodent or water intrusion events. The inspection produces a recorded video file you can review, and if cleaning is warranted, we apply the inspection fee toward the full service price. This is also the standard first step for our Free Second Opinion service: bring another company’s written estimate, and we’ll video-inspect to verify their scope against what we actually find.

Brands We Service for Air Duct Cleaning
CleanRun crews are trained to clean and service ductwork connected to all major HVAC brands, with particular depth of experience on systems common to Northern Virginia installations. We’ve serviced hundreds of Aprilaire whole-house air cleaners and humidifiers, often integrated into Trane and Carrier systems in Fairfax homes built during the 2005-2015 boom; we stock Aprilaire replacement media and understand how their bypass and powered models interface with duct geometry during cleaning. Our work with Abatement Technologies equipment extends to both the portable HEPA air scrubbers we deploy during cleaning and the built-in filtration systems some Fairfax homeowners have added for allergy management.
We also maintain Guardsman-treated flex duct and register components where original installation specified antimicrobial lining, and we use Rotobrush brush systems calibrated for the duct diameters typical of residential construction in Fairfax County. Whether your home runs a builder-grade system from 1995 or a high-efficiency variable-speed unit installed last year, we clean to the manufacturer’s duct specifications without voiding warranties. If you have a brand not mentioned here, we research its requirements before arrival and adjust our process accordingly.
BeforeAfterSigns You Need Air Duct Cleaning Right Now
- Visible dust puffing from registers when the system starts. This indicates loose accumulation in the supply ducts near the register, which means deeper loading likely exists throughout the run. In Fairfax’s seasonal climate, where systems sit idle through mild springs and falls, settled debris dries and fragments, making this symptom more common after the first heating or cooling cycle of the season.
- Uneven temperatures between rooms on the same floor. When one bedroom runs five degrees warmer than another, restricted airflow from duct blockage is a leading cause, especially in Fairfax’s two-story colonials and split-foyers where long duct runs serve distant rooms. Cleaning restores designed airflow without the cost of duct modification.
- Persistent musty or stale odors when HVAC runs. Odors indicate biological activity or water intrusion in the duct system, both of which accelerate in Fairfax’s humid summers when attic and crawl-space ducts sweat against poorly insulated surfaces. Cleaning removes the source material; our photo record confirms where the odor originated.
- Increased dust accumulation on surfaces within days of cleaning. If you’re dusting more often than you used to, your ducts may be redistributing particulate faster than your filtration captures it. This is particularly noticeable in Fairfax’s newer neighborhoods near Fairfax Corner and Fairfax Gateway, where construction activity in surrounding developments adds ambient particulate load.
- No record of duct cleaning since you purchased the home, or ever. For Fairfax homes built 2015-2025 and purchased at peak market prices, undocumented duct condition is an unknown liability. We frequently find original construction debris, including drywall dust and wood shavings, in systems that have run 5-10 years without cleaning.
Our Air Duct Cleaning Process - Step by Step
- 1
Written estimate and scope confirmation. We arrive, inspect your accessible ductwork with a borescope, and deliver a written price before any work begins. Haven Standard Clause 1 requires this; there is no “call for a quote” fallback. The scope names every duct run, the equipment we’ll use, and the flat price for the complete job.
- 2
System protection and access. Technicians lay protective covering, seal registers not being cleaned to maintain negative pressure, and cut access ports in trunk lines where needed. We use Aprilaire and Abatement Technologies HEPA-filtered vacuums to capture dislodged debris at the source, not redistribute it.
- 3
Mechanical agitation and extraction. Rotobrush systems or compressed-air whips dislodge debris from duct walls while the vacuum maintains continuous suction. We adjust brush stiffness and air pressure based on duct material, flex duct versus sheet metal, to avoid damage.
- 4
Component-level cleaning. The plenum, registers, and accessible air handler surfaces are cleaned and inspected. In Fairfax homes with integrated humidifiers or UV lights, we note their condition and flag maintenance needs without upselling replacement.
- 5
Photo documentation and final walkthrough. Before-and-after images from inside every duct run are compiled into your job record, delivered with the final invoice. We review the photos with you, confirm satisfaction, and activate the 365-Day Done Right Promise in writing.
How Much Does Air Duct Cleaning Cost in Fairfax?
A typical residential full system cleaning in Fairfax runs $380-$780 for a single HVAC system with 8-16 duct runs, depending on system accessibility, contamination level, and whether the home has flex duct, sheet metal, or a combination. Supply-only or return-only cleaning, requested less commonly, ranges $180-$340 per subsystem. Commercial systems are scoped individually based on square footage and duct complexity, with written estimates delivered on-site.
Several factors move the price within these ranges. Homes with crawl-space or attic air handlers require additional access time. Heavy contamination from years of deferred maintenance, or from recent construction or rodent activity, may extend cleaning duration. Multiple HVAC zones add duct runs and complexity. We price by the complete system, not per vent, so a home with 12 registers pays the same flat rate as an identical home with 10 registers if the system configuration is comparable.
To avoid overpaying, reject any quote that cannot be put in writing before work starts, and be wary of per-vent pricing or teaser rates that balloon once the crew is inside your home. CleanRun’s Free Second Opinion service lets you compare any written competitor quote against our scoped, fixed-price estimate at no cost. Every estimate includes the photo record deliverable and the 365-Day Done Right Promise; there are no add-on fees for documentation or warranty activation.

Frequently Asked Questions - Air Duct Cleaning in Fairfax
Air duct cleaning is the mechanical removal of accumulated dust, debris, and biological material from the interior surfaces of your HVAC ductwork, plenum, and accessible components. In Fairfax homes, we commonly remove fine sediment from construction, pet dander, pollen, mold spores where moisture has intruded, and fragmented insulation from aging flex duct. The process does not sanitize or coat ducts; it removes the physical loading that restricts airflow and redistributes particulate into occupied spaces.
A typical residential full system cleaning takes 3-5 hours for a single HVAC system, depending on duct run count, contamination level, and access difficulty. Fairfax’s larger homes in neighborhoods like Fairfax Station or along the Occoquan may run longer due to extended duct networks or multiple air handlers. We schedule with time buffers and confirm expected duration in your written scope so you’re not waiting on an open-ended appointment.
Residential full system cleaning in Fairfax typically costs $380-$780 for a single system, with supply-only or return-only cleaning at $180-$340. Commercial pricing is scoped individually. The exact price depends on system size, accessibility, and contamination level, which we assess during our free on-site estimate and put in writing before any work begins. Call (571) 526-0015 for a written quote specific to your home.
Yes. We clean ductwork connected to all major HVAC and IAQ brands, including Aprilaire whole-house cleaners and humidifiers, Honeywell electronic air cleaners, and Carrier, Trane, Lennox, Rheem, and Goodman systems. Our crews carry common Aprilaire replacement media and understand how integrated components affect duct access and cleaning protocol. If you have a less common brand, we verify specifications before arrival.
We do not advertise same-day service because duct cleaning is a scheduled, diagnostic job that requires proper equipment loading and scope verification. For urgent situations, documented water intrusion, or post-remediation clearance needs, we maintain a priority scheduling queue with faster turnaround. All calls are answered by a live person, 24/7, who can assess urgency and assign the earliest appropriate slot.
Every job is backed by the 365-Day Done Right Promise: if the work is not right, CleanRun makes it right, in writing, without manager approval gates. This is not a marketing claim; it is a written guarantee delivered with your job record. Haven Standard Clause 1 also locks your price: the written estimate is the final price, period.
Clear a path to your HVAC unit, plenum, and all registers; secure pets in a separate room; and ensure we have driveway or street parking for our vacuum truck. We bring protective coverings for floors and furniture near work areas. If you have specific concerns about certain rooms or recent changes in system performance, note them before arrival so we can prioritize video inspection of those runs. Call (571) 526-0015 to schedule and discuss any access constraints.
