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.

AfterAbatement Technologies Duct Repair & Sealing in Ashburn: What to Know First
We provide independent Abatement Technologies duct repair & sealing in Ashburn, with most jobs completed in a single scheduled visit and a written price delivered before any panel comes off. As an independent Abatement Technologies service provider, we carry OEM and quality aftermarket parts for the HEPA-AIRE and PREDATOR series commonly found in Northern Virginia homes, and every repair is backed by our 365-Day Done Right Promise in writing. This page is for Ashburn homeowners who own Abatement Technologies air filtration or abatement equipment connected to ductwork and need sealing, repair, or leak remediation they can verify. Call (240) 771-1508 for a free estimate.
How Abatement Technologies Products Fail - and How We Fix Them
- HEPA-AIRE SAH2 series: cracked flex duct at the unit connection. The SAH2’s high-static blower creates more vibration at the plenum junction than standard HVAC units, and in Ashburn’s clay-heavy soil zone, seasonal foundation settling transfers stress to that connection point. We replace the damaged flex section with UL-181 rated duct and reinforce with mastic sealant and mechanical strap support, not tape alone.
- PREDATOR 750: air leaks at the filter rack interface. The 750’s gasket channel is prone to compression set after repeated filter changes, especially in homes near Loudoun Station where construction dust loads accelerate filter cycling. We machine the sealing surface flat, install a continuous EPDM gasket, and verify with a smoke pencil test before closing the panel.
- HEPA-AIRE PAS2400: metal duct fatigue at the negative-pressure port. The PAS2400’s extraction port sees cyclic loading during portable use, and thin-gauge OEM ductwork at this junction often cracks at the bead. We sleeve the area with 26-gauge galvanized and seal with fiber-reinforced mastic rated for negative-pressure cycling.
- Abatement Technologies inline HEPA: bypass leakage around the housing. The clamp-style housings on older Abatement Technologies inline units loosen over thermal cycles, particularly in Ashburn attics where summer peak temperatures exceed 140°F. We reseat the housing, replace the neoprene seal, and torque to manufacturer spec with a calibrated driver.
- PREDATOR 1200: flex duct collapse at the return plenum. The 1200’s higher airflow rate can create negative-pressure zones that pull unsupported flex duct flat, a problem we see frequently in townhomes with long horizontal runs. We install internal wire support rings and transition to rigid duct where the static pressure calculation warrants it.
Our Abatement Technologies Duct Repair & Sealing Process
- 1
Visual and camera inspection of every duct run. We photograph the interior of each accessible section before touching a screw - Tomas Reyes’s standard practice since 2013, because the picture should do the talking first.
- 2
Static pressure test across the Abatement Technologies unit. We measure pre- and post-filter differential to identify whether the leak is upstream, downstream, or at the unit itself.
- 3
Parts decision: OEM Abatement Technologies or quality aftermarket. OEM gaskets and housings are stocked for current-series units; for discontinued lines, we source aftermarket components that meet or exceed UL-181 and SMACNA standards, with the trade-off explained in writing.
- 4
Repair and seal with documented methods. Mastic sealant is applied to spec thickness, mechanical fasteners are torqued to value, and flex duct is supported per IRC M1601.4.1.
- 5
Post-repair verification. Smoke pencil, static pressure comparison, and thermal camera scan where insulation is involved.
- 6
Photo record delivery and written guarantee. Before-and-after images of every repaired run, plus the 365-Day Done Right Promise, are delivered as standard job documentation under Haven Standard Clause 1.

What moves the price: accessibility (attic vs. basement), length of damaged run, and whether the Abatement Technologies unit must be de-energized for safe access. We deliver one flat price per system, agreed in writing before work starts - no per-vent add-ons, no post-arrival surprises. Call (240) 771-1508 for a free estimate.
Why Ashburn Homeowners Call CleanRun Air Duct Cleaning Ashburn for Abatement Technologies Work
We’ve logged hundreds of jobs in Ashburn, including properties near Loudoun Station where the mix of newer construction and high-density townhomes traps more construction-phase debris than homeowners expect. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they arrive with equipment from Abatement Technologies, Rotobrush, Nikro, Honeywell, Aprilaire, and Guardsman - brands customers can verify independently. The 365-Day Done Right Promise is backed in writing on every job, not stated in marketing copy and forgotten. We also service Lennox, Trane, and Carrier systems, so multi-unit or mixed-brand homes don’t need multiple contractors. Tomas Reyes, who picked up his technical foundation at Manhattan’s Apex Technical School and spent two decades inside Northern Virginia ductwork, still photographs every return air plenum before touching a single screw.
FAQs
No - independent repair does not void the warranty if performed to manufacturer specifications and using compliant parts. We document our methods and parts sources so you have a record if warranty questions arise. Call (240) 771-1508 if you need clarification on your specific unit’s coverage.
Replacement is the better path when flex duct shows multiple punctures, delaminated insulation, or mold penetration that cannot be remediated without removing the liner. We photograph the damage and show you the condition before recommending either option. Call (240) 771-1508 for an inspection and written assessment.
Not always - current-series gaskets and housings are available OEM, but for discontinued units, quality aftermarket components meeting UL-181 and SMACNA standards perform equivalently at lower cost. We explain the trade-off in writing before you decide. Call (240) 771-1508 to discuss your unit’s parts situation.
Most single-point repairs are completed in two to four hours; multi-run sealing or plenum reconstruction may extend to a full day. We schedule by the job, not by the hour, so the price does not change if the work runs longer than estimated. Call (240) 771-1508 to schedule.
Every job includes a Documented Photo Record of every duct run, before and after, delivered as part of the standard job record - a practice CleanRun has held since its first job in 2013. You’ll see the crack, the seal, and the test result. Call (240) 771-1508 to book a documented repair.
