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 Ashburn: What to Know First
We provide independent Abatement Technologies air quality and sanitizing in Ashburn, with most jobs scheduled within a few business days and completed in a single visit. Every job starts with a written price before any work begins - Haven Standard Clause 1 - and ends with a documented photo record of every duct run, delivered as part of the standard job record. This page is for Ashburn homeowners who own Abatement Technologies air quality equipment and need mold treatment, bacteria sanitizing, odor removal, UV light installation, air purifier installation, or allergen reduction done by technicians who know the product line. Call (240) 771-1508 for a free estimate.
How Abatement Technologies Products Fail - and How We Fix Them
- PREDATOR 750 Series: UV lamp degradation in high-humidity seasons. The 750-series UV-C lamps lose output faster than rated in Ashburn’s July-August humidity spikes, when crawlspace and attic units run near condensation point. We meter actual UV output with a radiometer, replace lamps at documented threshold (not just annually), and verify the quartz sleeve hasn’t clouded from mineral film.
- HEPA-AIRE PAS2400: Seal fatigue at the filter-to-housing interface. The PAS2400’s gasket channel traps fine debris that abrades the seal during filter changes, creating bypass that defeats HEPA capture. We inspect the channel with a borescope, clean it to bare surface, and install OEM gaskets - aftermarket gaskets in this unit tend to shore-hardness mismatch and leak within six months.
- ABATEMENT CAP600: Carbon media saturation in homes near construction zones. The CAP600’s activated carbon loads faster in Ashburn’s active development corridors - near Loudoun Station, Brambleton, or along Route 7 expansion - where diesel particulate and drywall dust spike VOC load. We test breakthrough with a PID meter, replace carbon only when saturated (not on calendar), and document the differential pressure across the bed.
- PORTA-AIRE PA3000: Blower motor bearing wear from continuous-duty cycling. The PA3000’s motor is rated for intermittent use but gets pressed into 24/7 service during allergy season or post-remediation hold periods. We check bearing play and winding resistance, replace with OEM-spec bearings (not generic HVAC blower motors), and set proper duty-cycle programming.
- UV2 series: Ballast failure from voltage sag during Loudoun County summer grid load. Ashburn’s rapid growth has strained local transformer capacity; we’ve logged UV2 ballast failures clustered in late-afternoon July outages. We test ballast output under load, install surge-rated replacement ballasts where indicated, and note the condition in the job record for warranty documentation.
Our Abatement Technologies Air Quality & Sanitizing Process

- 1
Photo documentation before touch. We photograph every return air plenum, filter housing, and UV lamp cavity before removing a single panel - Tomas Reyes started this practice in 2013, and we still deliver it on every job.
- 2
Written scope and price. We deliver a written price with line-item breakdown before any work begins. No exceptions. Haven Standard Clause 1.
- 3
Diagnostic with trade-grade meters. We use a radiometer for UV output, PID for VOC detection, particle counter for filtration verification, and manometer for pressure differential - each reading logged to the job record.
- 4
OEM or verified-equivalent parts. We stock Abatement Technologies OEM lamps, gaskets, and ballasts. Where OEM is back-ordered, we use manufacturer-crossed equivalents from Honeywell or Aprilaire, never generic, and we document the substitution in writing.
- 5
Post-repair verification and photo record. We re-test with the same meters, photograph every completed run, and deliver the full record to the customer before we leave the driveway.
- 6
365-Day Done Right Promise activation. The written guarantee goes into effect the moment we finish - not pending manager approval, not conditional on a survey response.

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 construction-phase debris still circulates in ductwork years after move-in. 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 an Ashburn home has mixed-brand equipment, we don’t subcontract or guess. The 365-Day Done Right Promise is backed in writing on every job, and the documented photo record means you don’t take our word for what was inside your ducts. I’ll show you the before photo first - then we can talk about what happens next.
FAQs
Abatement Technologies warranties the product, not the installation environment; our sanitizing work does not void the equipment warranty, but we document our methods and parts used so any future warranty claim has a clear service history. We keep those records for the full 365 days of our Done Right Promise. Call (240) 771-1508 if you need a copy for your files.
We deliver a documented photo record of every duct run, before and after, as a standard deliverable on every visit - not an upsell, not a link you have to request. The photo shows the plenum surface condition, the application pattern, and the post-treatment verification meter reading. If we can’t photograph it, we didn’t do it.
We recommend repair when the unit’s core components - blower housing, filter frame, UV cavity - are structurally sound and replacement parts are available with documented spec match. We recommend replacement when corrosion has compromised the housing integrity or when the unit’s efficiency class is three generations behind current standards. We give both numbers in writing, with a free second opinion on any competitor’s replacement quote.
The low quotes we’ve reviewed in Ashburn typically omit the photo record, use generic UV lamps without output verification, or quote per-vent pricing that balloons once the crew is on-site. Our price is the full price, written before work starts, with no per-vent add-ons. The difference is usually visible in the photo record afterward.
UV lamps need output verification annually in Ashburn’s humidity; HEPA housings need seal inspection every filter change; carbon media needs saturation testing, not calendar replacement. We don’t sell maintenance contracts - we test and document what actually needs doing, then put the written price in front of you. Call (240) 771-1508 to schedule.
