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.
Abatement Technologies Air Quality & Sanitizing in Alexandria: What to Know First
We provide independent Abatement Technologies air quality and sanitizing services in Alexandria, with most jobs scheduled within a few business days and completed in a single visit. A typical Abatement Technologies system treatment runs $340-$780 depending on whether we’re addressing mold in a PREDATOR 800 series HEPA unit, installing UV-C lamps in a CAP600-UV air scrubber, or performing full bacteria sanitizing after water damage. Every job starts with a written price before any work begins, under Haven Standard Clause 1, and concludes with a documented photo record of every treated component. This page is for Alexandria homeowners who own Abatement Technologies equipment and need sanitizing, odor removal, or air quality improvement that protects their warranty and actually changes what they breathe.
Call (240) 318-7712 for a free estimate. We’ll put our written number next to any competitor’s quote at no cost.
How Abatement Technologies Products Fail - and How We Fix Them
- PREDATOR 800 series HEPA units develop microbial loading in the filter plenum. The sealed gasket design traps humidity from Alexandria’s Potomac-adjacent summers, creating ideal conditions for mold colonization behind the HEPA media where homeowners can’t see it. We remove the filter bank, photograph the plenum condition, treat with EPA-registered sanitizer, and reinstall with a documented seal test. The duct doesn’t lie - we just show you what’s in it.
- CAP600-UV and CAP1200-UV air scrubbers lose UV-C lamp intensity without warning. The OEM lamps degrade to sub-therapeutic output around the 9,000-hour mark, but the indicator light stays green. We meter actual UVC output at the coil surface; if it’s below 40 µW/cm², we replace with Abatement Technologies-specified lamps or document-equivalent aftermarket units that maintain warranty compliance.
- BD2P and BD4P portable HEPA systems harbor bacteria in the condensate pan. These units see heavy use in Alexandria’s older Del Ray homes with basement moisture issues, and the shallow pan design doesn’t fully drain. We disassemble the lower housing, treat the pan and blower wheel with antimicrobial, and modify the drain pitch where possible to prevent recurrence.
- ABATEMENT H2000 series negative air machines develop odor from contaminated pre-filters. The woven polyester pre-filter media holds organic debris from remediation jobs; in Alexandria’s humid shoulder seasons, this produces a musty exhaust smell even when HEPA tests pass. We source the correct 24x24x2 OEM pre-filters or verified equivalents, and we photograph the filter loading before replacement so you see the difference between surface dust and embedded contamination.
- UVGI systems in Abatement Technologies air handlers suffer from improper lamp placement. We’ve found lamps installed 18 inches from the coil in Alexandria townhomes where the original contractor never read the 6-inch specification. We measure, reposition, and document the new lamp-to-coil distance with a photo - this single correction often eliminates the “still smells” callback that frustrates homeowners who paid for sanitizing that never reached the target surface.
Our Abatement Technologies Air Quality & Sanitizing Process

- 1
System identification and access. We record the Abatement Technologies model, serial, and installation date, then remove access panels to photograph the internal condition before any equipment leaves our van.
- 2
Contamination assessment. We use borescope cameras to inspect the plenum, coil, and blower housing, documenting mold, biofilm, or debris loading with location-stamped photos that become part of your job record.
- 3
Written scope and price. Under Haven Standard Clause 1, we deliver a written price for the exact treatment - sanitizer application, UV lamp replacement, filter changeout, or combined service - before any work begins. No exceptions.
- 4
Treatment execution with Abatement Technologies-compatible methods. We use EPA-registered sanitizers at manufacturer-specified dwell times, install OEM or documented-equivalent UV lamps, and verify HEPA filter integrity with a particle counter where applicable.
- 5
Post-treatment verification and photo record. We photograph every treated component after completion, run the system through a full cycle to confirm normal operation, and deliver the before-and-after photo record as a standard deliverable - not an upsell.
- 6
Written guarantee. Your job file includes the 365-Day Done Right Promise in writing. If the odor returns, the mold regrows, or the UV meter reads low, we make it right.

Why Alexandria Homeowners Call CleanRun Duct Repair & Cleaning for Abatement Technologies Work

We’ve serviced Abatement Technologies equipment in Alexandria since 2013, including the tight mechanical closets of Old Town rowhouses and the converted attic systems in Rosemont bungalows where flex duct and HEPA units share cramped quarters. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we publish our license number where you can find it - not buried in a footer.
The 365-Day Done Right Promise is backed in writing on every job, not just stated in marketing copy. Our equipment roster includes Abatement Technologies, Rotobrush, Nikro, Honeywell, Aprilaire, and Guardsman - brands you can look up before you agree to anything. We also service Lennox, Trane, and Carrier systems, so when your Abatement Technologies unit integrates with a mixed-brand HVAC setup, we don’t guess at the interaction.
Tomas Reyes grew up in Queens, NY, trained at Apex Technical School in Long Island City, and spent two decades working through every duct configuration the mid-Atlantic climate can produce. He and his crew have handled the pinched flex duct and humidity-loaded plenums particular to Alexandria’s older housing stock, including colonial-era homes near Del Ray where airflow problems masquerade as equipment failures.
FAQs
No, when performed by a technician using EPA-registered products and OEM-specified replacement parts. We document every sanitizer concentration, dwell time, and lamp specification in your job record so warranty coverage remains intact. As an independent Abatement Technologies service provider, we have no manufacturer affiliation - we simply follow their published maintenance guidelines to the letter. Call (240) 318-7712 if you need documentation for a warranty claim.
We deliver a documented photo record of every treated surface, plus post-treatment UV intensity readings or particle counts where applicable. The before-and-after photo record is included as standard, not sold as an upgrade. If you still smell the original odor within 365 days, Haven Standard Clause 5 requires us to return and make it right at no charge.
The low quotes usually involve a quick spray of generic sanitizer and no access-panel removal. We’ve opened Abatement Technologies units in Alexandria homes where the “cleaning” company never removed the HEPA filter bank - the mold was still there, just hidden. Our written scope specifies exactly which components get treated, with photos to prove it.
Most units under 10 years old with intact housings respond well to professional sanitizing and UV retrofit. We recommend replacement when the blower motor shows electrical faults, the plenum is corroded through, or repair costs exceed 60% of replacement value - and we’ll put that calculation in writing, with both numbers, before you decide.
UV lamps require annual intensity verification; HEPA units in Alexandria’s humid climate benefit from plenum inspection every 18-24 months. Homes with pets, recent water damage, or occupants with respiratory conditions may need more frequent service. We don’t sell maintenance contracts - we’ll tell you what we found and let you set the schedule.
