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 Alexandria: What to Know First
We provide independent Abatement Technologies duct repair & sealing in Alexandria, typically completing single-zone repairs in one visit and whole-system sealing in two. Every job starts with a written price before any panel comes off, and every duct run is photographed before and after so you can see what was actually done. Call (240) 318-7712 for a free estimate with no “call for a quote” runaround.
This page is for Alexandria homeowners who own an Abatement Technologies air filtration or pressure-monitoring system tied to their ductwork and have noticed uneven temperatures, rising energy bills, or visible damage at the plenum connections. If your system includes the HEPA-AIRE or PREDATOR series housings common in Northern Virginia installs from 2015 to 2022, the duct interface points are where we’ve found the most preventable energy loss.
How Abatement Technologies Products Fail - and How We Fix Them
- HEPA-AIRE PAS2400/PAS1200 filter housing gasket compression. The foam gasket between the housing and the return plenum compresses over 3-5 years in Alexandria’s humidity cycle, creating a bypass leak that dumps unfiltered attic air directly into your living space. We remove the housing, machine-surface the plenum flange, and reinstall with a fresh silicone-impregnated gasket rated for the PAS series bolt pattern. The duct doesn’t lie - we just show you what’s in it.
- PREDATOR 600/800 negative air machine flex-duct collar fatigue. The vibration-isolated collar on these portable units, when hard-piped into permanent ductwork by a previous contractor, develops circumferential cracks at the clamp point. We replace the rigid transition with a properly supported flex segment and vibration dampener, not just another hose clamp.
- Abatement Technologies CAP600/ CAP1200 central air purifier plenum sag. The added weight of these in-line units, installed in horizontal return plenums without supplemental support, causes the sheet metal to belly downward and separate at the drive cleats. We install angle-iron support brackets tied to joist structure, then reseal with mastic and mesh - not tape alone.
- BD2K/BD4K bed bug diesel heater duct adapter thermal cycling damage. These temporary-use adapters, sometimes left in place after remediation, are not rated for continuous HVAC operation. The thin aluminum fatigues at the crimp joints. We remove the adapter and fabricate a proper galvanized transition, or return the duct to original configuration if the adapter served no ongoing purpose.
- Abatement Technologies HEPA-AIRE Guardian series bypass damper seal failure. The internal bypass damper on Guardian units, when stuck partially open due to degraded neoprene seals, creates a constant pressure imbalance that manifests as whistling at bedroom registers. We disassemble the housing, replace the damper seal with OEM-spec neoprene, and verify closure torque with a manometer - not guesswork.
Our Abatement Technologies Duct Repair & Sealing Process
- 1
Arrival and scope confirmation. The technician identifies themselves by name, verifies the Abatement Technologies model and serial, and confirms the written price range before touching equipment. Haven Standard Clause 1: Written Price Before Work Starts.
- 2
Visual and camera inspection. We photograph every duct run, plenum connection, and the Abatement Technologies unit interface. In Alexandria’s older Del Ray colonials, we often find flex duct pinched behind knee walls where previous work compressed it.
- 3
Diagnostics and parts decision. We determine whether the repair requires OEM Abatement Technologies gaskets and hardware, or if a quality aftermarket solution meets specification. We explain the difference and document the choice in writing.
- 4
Repair and seal. We execute the repair using mastic sealant and fiberglass mesh for permanent joints, mechanical fasteners for structural connections, and pressure-rated flex duct where vibration isolation is required. No tape-only repairs.
- 5
Pressure test and photo record. We verify seal integrity with a digital manometer, then photograph every completed joint. The customer receives the full photo record and written scope as standard deliverables, not extras.
- 6
365-Day Done Right Promise activation. The written guarantee is dated and signed before we leave. If the seal fails or the repair needs adjustment within one year, we make it right.

Why Alexandria Homeowners Call CleanRun Air Duct Cleaning Alexandria for Abatement Technologies Work
We’ve been documenting every duct run in Alexandria since 2013, and we’ve learned that Abatement Technologies installations here have specific failure patterns tied to the mid-Atlantic humidity cycle and the way Northern Virginia contractors often hard-mount vibration equipment. Tomas Reyes, our owner, spent two decades working through every duct configuration this climate produces before establishing CleanRun, and he still pulls access panels personally on complex jobs.
Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so when your Abatement Technologies unit interfaces with a mixed-brand HVAC setup, we don’t guess at compatibility. The 365-Day Done Right Promise is backed in writing on every job, not just stated in marketing copy. And the photo record? You get it every time, because vacuum noise without documentation is not a service.
FAQs
No, if the repair is performed by a qualified technician using specification-grade parts and does not modify the unit’s electrical or filtration components. As an independent Abatement Technologies service provider, we document every gasket and fastener part number so warranty claims remain clean if you ever need factory support. Call (240) 318-7712 and we’ll review your specific model’s warranty terms before scheduling.
Most PAS and CAP series gaskets and hardware ship within 3-5 business days from Abatement Technologies distribution. For PREDATOR collar assemblies, we stock quality aftermarket equivalents that meet specification and can complete the repair same visit. If you prefer OEM-only, we’ll order it and schedule the repair when it arrives - no deposit required.
Repair the duct connection if the unit’s filtration performance is still adequate and the housing itself is structurally sound. Replace the unit if the housing is cracked, the blower motor is failing, or the filter media is discontinued. We photograph both the duct interface and the unit interior so you can see the difference and make an informed decision.
You receive a dated photo record of every duct run, before and after, plus the digital manometer reading showing pressure hold at the repaired joints. If a technician cannot show you what was inside your duct and what changed, they did not perform documented work. This has been our standard since 2013.
Yes. Mixed-brand installations are common in Alexandria, particularly in homes built between 2015 and 2022 where the builder specified one brand for HVAC and the homeowner added Abatement Technologies filtration later. We carry fittings and transition hardware compatible with all three brands and document the interface points in our photo record.
