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.

AfterFull System Cleaning in Fairfax, VA
A full system cleaning covers every component air passes through before it reaches your living space: supply and return duct runs, the main plenum (the central distribution box connected directly to your air handler), branch lines, registers, and the air handler cabinet itself. In Fairfax, a typical single-family home built between 1985 and 2010 carries between 12 and 22 duct runs, and most of them have never been cleaned since the house was built. A single-register vacuum service touches maybe four of those runs. A full system cleaning touches all of them, documented on camera, with a written price before anything opens.
If you want to understand where full system cleaning fits inside the broader service, visit our Air Duct Cleaning in Fairfax page for a complete breakdown of what each service level includes and when each one applies. And if you have a competitor’s written quote you’re comparing against, call us at (571) 526-0015 – we’ll put our number next to theirs in writing, at no charge, before you make any decision.
When You Need Full System Cleaning
Not every home needs a full system cleaning on the same schedule. In Fairfax specifically, a few local conditions push the timeline earlier than the national average suggests.
- Your home sat vacant or under renovation for more than 60 days. Construction dust in Fairfax contains fine drywall particulate and cellulose from older insulation – both of which pack into duct elbows and stay there. A camera inspection after a renovation almost always shows visible debris at the first bend in every run that wasn’t sealed during the work.
- You’re seeing uneven airflow between rooms on the same floor. In older neighborhoods like Fair Lakes and Mantua, homes with two-story layouts often have original duct runs that have collected enough debris near the plenum to measurably reduce static pressure in the branch lines furthest from the air handler. Rooms at the end of the run get noticeably less air.
- Your filters are loading faster than the manufacturer’s rated interval. If a MERV-11 filter that’s rated for 90 days is visibly gray at 30, the system is pulling from somewhere – and that somewhere is usually a duct that hasn’t been cleared in years.
- You’ve had a moisture event: a slow HVAC drain line leak, a basement flood, or a roof intrusion above a duct chase. Fairfax’s humidity profile from May through September is high enough that even minor standing moisture in a duct run can support biological growth inside 48 to 72 hours. A full system cleaning with camera documentation is the only way to confirm what’s actually present.
- You purchased the home in the last 12 months and have no cleaning records. Fairfax home sale disclosures don’t require duct cleaning documentation, and most sellers don’t have it. The camera record from a full system cleaning becomes part of your baseline home documentation – useful for future HVAC maintenance conversations and resale.
- A household member has been diagnosed with asthma, chronic sinusitis, or an airborne allergen sensitivity that wasn’t present at a previous address. We photograph what we find before saying a word about what to do next. If the camera shows a clean system, we tell you that in writing too.
Our Full System Cleaning Process
Every step below is the same whether we’re performing Residential Duct Cleaning in a townhouse in Penderbrook or a four-bedroom colonial in Oakton. The process doesn’t change based on square footage – it scales.
- Written scope and price delivered before work starts. Under Haven Standard Clause 1, no technician opens a single panel without a written price in your hand. We count the runs, identify the air handler type, note any accessible flex duct versus hard pipe, and write the number down. That number doesn’t change unless you ask us to add something. “Call for a quote” doesn’t exist here.
- Pre-cleaning camera inspection of every run, photographed. Using a flexible inspection camera, we photograph the interior of each duct run before any equipment runs. What we find is documented: debris depth at the first elbow, any visible biological growth, gaps at joints, and the condition of the liner. You see the before photos. This has been standard practice on every CleanRun job since 2013.
- Negative-pressure extraction established at the air handler. Negative-pressure extraction means we connect our main collection unit – Nikro equipment on most Fairfax jobs – directly to the air handler cabinet and create a controlled vacuum through the entire system. This pulls loosened debris toward the collection point rather than redistributing it through your home. The alternative (a shop-vac at each register) moves debris around; negative-pressure extraction removes it.
- Mechanical agitation through every supply and return run. Negative pressure alone doesn’t dislodge compacted debris at elbows and joints. We run Rotobrush rotary brushing equipment through each duct run to break material free from the duct wall, then the established negative pressure carries it out. For rigid metal duct, this combination cleans the full cross-section of the run. For flex duct, we adjust technique to avoid liner damage and document the liner condition as we go.
- Air handler cabinet cleaning and plenum clearance. The plenum and air handler cabinet collect what every duct run sheds over years of operation. We clean the cabinet interior, blower wheel (if accessible without refrigerant handling), and evaporator coil surround. On Fairfax homes with Aprilaire whole-home filtration installed at the air handler, we note filter condition and media age as part of the written job record.
- Post-cleaning camera inspection and photo record delivered. Every run gets photographed again after cleaning. The before and after images are organized by run and delivered to you as a standard part of the job record – not an optional add-on. If a run shows a condition we couldn’t fully resolve (a collapsed flex section, a disconnected joint inside the wall), we photograph it, note it in writing, and explain what the repair path looks like. That’s the job record, and it’s yours.
BeforeAfterFull System Cleaning Pricing in Fairfax
Full system cleaning in Fairfax runs between $399 and $749 for most single-family homes. The range reflects real variables, not a bait-and-switch – here’s what moves the number.
| Variable | Typical Impact on Price |
|---|---|
| Number of duct runs (supply + return combined) | Base pricing covers up to 10 runs; each additional run adds $18-$28 |
| Duct material: rigid metal vs. flex duct vs. fiberboard | Fiberboard duct (common in Fairfax homes built 1975-1995) requires adjusted technique and adds $40-$80 |
| Air handler location: accessible basement vs. attic crawl vs. closet chase | Attic or tight closet installs add $30-$60 for setup time |
| System age and debris load | Systems not cleaned in 10+ years may require a second mechanical agitation pass; adds $50-$90 |
| Add-on sanitizing treatment (Abatement Technologies-compatible fogger application) | $80-$150 depending on system volume |
What doesn’t affect the price: the neighborhood you’re in, how large your house looks from the outside, or whether you mentioned a competitor’s number when you called. The written price is based on your actual system, not on what the market will bear that week.
Every full system cleaning in Fairfax includes the pre- and post-cleaning camera inspection, the documented photo record, and coverage under the 365-Day Done Right Promise – all at the written price, with no line items added at the door.

FAQs – Full System Cleaning
How long does a full system cleaning take in a typical Fairfax home?
Most single-family homes in Fairfax with 12 to 18 duct runs take between 3 and 4.5 hours from first panel to final photo. Larger homes in areas like Great Falls or Clifton with 20-plus runs, multiple air handlers, or significant debris load run 5 to 6 hours. We don’t quote a time and then rush the camera inspection to meet it – the photo record is part of every job, and that step isn’t skipped. The technician assigned to your job will confirm the estimated duration when the written scope is delivered, before work starts. Call (571) 526-0015 for a same-day or next-available appointment.
Is full system cleaning worth it if my ducts were cleaned three or four years ago?
It depends on what was actually done three or four years ago, and whether there’s documentation to confirm it. A single-register vacuum service performed by a $79 coupon company covers a fraction of the system – it doesn’t establish negative-pressure extraction or photograph the runs beyond the register opening. If you have a before-and-after photo record from the prior service showing the full interior of each run, that’s a real data point. If you have a receipt and no photos, bring us the receipt and we’ll do a no-charge camera check at two or three representative runs before quoting anything. That way you’re deciding based on what the camera actually shows, not on an assumption either direction. Call (571) 526-0015 to schedule.
What’s the difference between full system cleaning and a standard duct cleaning?
Full system cleaning addresses every component air passes through: all supply runs, all return runs, the plenum, the air handler cabinet interior, and the registers. A standard duct cleaning – as commonly advertised in Fairfax – typically means a technician visits each register with a vacuum and moves on. It may address 20 to 30 percent of the total duct surface area. Full system cleaning uses negative-pressure extraction established at the air handler, mechanical agitation through every run, and camera documentation before and after each run. The difference isn’t a marketing category – it’s a measurable difference in scope, equipment, and the amount of the system that actually gets addressed. Our home page lists every service we offer, with the same written-price structure applied to each one.
Does CleanRun clean the air handler coil as part of full system cleaning?
We clean the air handler cabinet interior, the blower wheel where accessible without refrigerant-circuit work, and the area around the evaporator coil. A full evaporator coil cleaning that requires removing the coil from the refrigerant circuit is HVAC technician work under EPA Section 608 – that’s not duct cleaning, and any company telling you otherwise is either misstating the scope or operating outside their credentials. What we do photograph and document is the visible coil face condition and the blower wheel. If either shows a condition that warrants an HVAC technician visit, we note it in the written job record with a photo so you have something concrete to hand a licensed HVAC contractor. Call (571) 526-0015 with questions about what’s included before booking – the written scope will spell it out exactly.
Why Fairfax Homeowners Choose CleanRun
Tomas Reyes started CleanRun in 2013 with a straightforward position: write the price down before touching anything, photograph the inside of every run before and after, and back the work in writing for 365 days. That position came directly from watching what the $79-coupon end of this industry actually delivers – a loud shop-vac at the visible registers and a receipt for a service that didn’t happen in most of the duct system.
Twelve years later, CleanRun has completed full system cleanings in over 52,000 homes. Every one of them started with a written price. Every one of them ended with a photo record the customer keeps. The 365-Day Done Right Promise isn’t a marketing line – it’s a written commitment delivered with the job record, not issued from a manager’s discretion six months later.
For Fairfax specifically: Tomas and the CleanRun team know the duct configurations common to the townhouse clusters in Fair Lakes, the two-story colonials throughout Burke, the older flex-duct installations in Reston-adjacent neighborhoods, and the fiberboard duct systems still operating in homes built during Fairfax’s 1975-1995 construction boom. That knowledge shows up in the accuracy of the written scope and in what the camera finds at the first elbow, not in what we say about ourselves before the job starts.
Background-checked, uniformed technicians operating under Haven Standard Clause 3 (Verified Crews) are identified by name before arrival. Equipment used on Fairfax full system cleaning jobs includes Rotobrush, Nikro, and Abatement Technologies units – professional-grade tools you can look up independently before agreeing to anything.
