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.

AfterNikro Air Duct Cleaning in Herndon: What to Know First
CleanRun Duct Repair & Cleaning provides independent Nikro air duct cleaning in Herndon, VA, with written prices delivered before any work begins and a documented photo record of every duct run included as standard. Most residential Nikro systems in Herndon homes are inspected, cleaned, and photographed within a single scheduled visit. We are not affiliated with or authorized by Nikro; we are an independent Nikro service provider with twelve years of documented jobs on these systems. If you own a Nikro air handling unit or portable duct cleaning system and need the ductwork that connects to it properly cleaned, call (571) 520-6317. We’ll put a written estimate in your hand before a single panel comes off.
How Nikro Products Fail - and How We Fix Them
- Nikro PS1000 and PS2000 Portable Power Vacuums - motor seal degradation in humid seasons. The rubber intake seals on these units harden faster than spec in Northern Virginia’s muggy Julys, pulling reduced airflow that leaves debris lodged in the main trunk. We replace the seal with a fluorocarbon-rated aftermarket equivalent that holds its shape above 85% RH, then verify static pressure recovery with a manometer before we sign off.
- Nikro SL4000 Slurry Vac crossover into duct cleaning - filter basket collapse under fine particulate. Herndon homes built 2015-2020 near the Dulles corridor often have compacted drywall dust and synthetic insulation fragments from rushed construction. The SL4000’s OEM basket pleats flatten under this load, bypassing debris into the blower. We source a reinforced stainless mesh basket from Abatement Technologies, document the differential pressure across it, and photograph the captured load.
- Nikro HP20 and HP30 Gas-Powered Vacuums - carburetor varnish from ethanol-blend fuel storage. These units sit in Herndon garages through winter, and the 10% ethanol in standard pump gas separates, gumming the idle circuit. The engine surges, the vacuum pulsates, and the duct run gets uneven agitation. We pull the carb, ultrasonic-clean it, and switch the customer to non-ethanol fuel protocol with a written maintenance note in the job record.
- Nikro 860284 and 860285 HEPA filter cartridges - premature loading in pollen-heavy spring cycles. Herndon’s tree canopy, especially the mature oaks around the historic downtown core along Elden Street, dumps pollen loads that saturate these cartridges in 18 months instead of the rated 24. We log the pressure drop, show the customer the loaded filter photo, and stock the replacement on the truck to avoid a return visit.
- Nikro duct cleaning whip assemblies - nylon bristle fatigue in rectangular metal ductwork. The standard whips work fine in round flex, but Herndon’s 1960s-1980s ranch stock uses rectangular galvanized trunks with sharp corners. The bristles mushroom and lose contact pressure. We swap to a carbon-steel skip-chain whip for metal runs, document the surface contact pattern with the borescope, and revert to nylon only where the system transitions to flex.
Our Nikro Air Duct Cleaning Process
- 1
Written price delivered on arrival. Haven Standard Clause 1: the scope and price are in writing before we touch the system. No exceptions.
- 2
Video inspection of every accessible duct run. We feed a lighted borescope through the plenum, the main trunk, and each branch. The camera shows a 3-inch debris build-up at the first elbow, or it doesn’t. We save the footage to the job record.
- 3
Equipment match to duct type. Nikro vacuum paired with Rotobrush contact agitation for flex duct, or Nikro negative-pressure extraction with skip-chain mechanical agitation for rigid metal. We name what’s being used in the written scope.
- 4
Component-level cleaning, not blow-and-go. Registers removed and washed, plenum hand-cleaned, blower wheel pulled and degreased if accessible. Each step photographed.
- 5
Post-cleaning video and static pressure test. We run the borescope again, capture the after condition, and measure system static against the pre-clean baseline. The numbers go in the report.
- 6
Documented Photo Record delivered, 365-Day Done Right Promise activated. Every photo, every measurement, every part number used, in a PDF within 24 hours. If it’s not right, we make it right. Backed in writing.

Why Herndon Homeowners Call CleanRun Duct Repair & Cleaning for Nikro Work
We’ve cleaned ductwork connected to Nikro equipment in Herndon since 2013, from the townhomes near Worldgate Drive to the single-family stock around Dranesville Road and the mature neighborhoods near the historic downtown core along Elden Street. Tomas Reyes and our crew know the difference between a Nikro unit that’s actually moving debris and one that’s just making noise. We also service Lennox, Trane, and Carrier systems, so when your ductwork feeds a mixed-brand setup, we don’t need a second truck.
Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise is not a policy subject to manager approval. It’s a written guarantee on every job. And the Documented Photo Record means you see what we saw, not just what we say we did.
Show the photo first. Then explain what it means. The estimate comes after that.
FAQs
No. Nikro’s warranty covers manufacturing defects in their equipment, not the condition of your ductwork. CleanRun’s cleaning methods do not alter Nikro unit internals beyond standard access panel removal. We document every panel screw and gasket condition in the photo record so there’s no dispute about what was touched.
Aftermarket HEPA cartridges meeting the same MERV and pressure-drop specs perform identically in our documented testing, at 30-40% lower cost. We stock both, specify the part number in writing, and let the customer choose. If you prefer OEM Nikro 860284 or 860285 cartridges, we order them and charge our cost plus a small handling fee, disclosed upfront.
The Documented Photo Record shows the inside of every run, before and after, with timestamps. We also measure system static pressure before and after cleaning. A properly cleaned system shows a measurable pressure recovery, typically 0.1-0.3 inches water column on residential units. The numbers and photos are in your job record PDF within 24 hours. If the documentation doesn’t match the work, the 365-Day Done Right Promise applies.
Yes, if the unit was last used on a Category 2 or 3 water loss and not fully decontaminated. We inspect the vacuum’s internal pathways with a borescope before connecting it to your duct system. If we find standing moisture or microbial residue, we clean and dry the unit on-site before proceeding, documented in the scope. Cross-contamination from water jobs to air systems is a real risk we don’t ignore.
Every 3-5 years for typical residential occupancy, sooner if you have pets that shed, recent renovation dust, or occupants with respiratory sensitivity. Herndon’s pollen load from mature oak canopy and the clay-heavy dust that tracks in from local construction zones both accelerate buildup. We inspect and advise; we don’t sell annual packages nobody needs. Call (571) 520-6317 for an exact assessment of your system condition.
