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 Air Quality & Sanitizing in Fairfax: What to Know First
CleanRun provides independent Abatement Technologies air quality and sanitizing service in Fairfax, with most jobs scheduled within a week and completed in a single visit. We deliver a written price before any work starts, and every job ends with a documented photo record of every duct run we touched. Typical whole-system sanitizing and air quality work for Fairfax homes with Abatement Technologies equipment runs $340-$780 depending on system size and what the inspection camera finds. This page is for homeowners in Fairfax and nearby who own Abatement Technologies air filtration or sanitizing equipment and want a technician who names the price upfront, photographs the work, and knows the difference between a PREDATOR 360 and a portable HEPA unit without reading the label twice. Call (571) 526-0015 for a free estimate.
How Abatement Technologies Products Fail - and How We Fix Them
- PREDATOR 360 and 600 series: UV lamp degradation without indicator failure. The lamp burns at reduced output for months after the status light still reads green, especially in Fairfax’s hard-water areas where mineral film coats the quartz sleeve faster than the manufacturer spec assumes. We pull and photograph the sleeve, measure actual UV-C output with a radiometer, and replace only when the data says so, not when a timer dings.
- Portable HEPA units (Abatement Technologies PREDATOR and HEPA-AIRE models): blower motor bearing wear from cyclic humidity. Fairfax’s summer dew points in the 70s cause condensation inside the housing when units cycle off in basements near Lake Anne or along Accotink Creek. The motor doesn’t fail outright; it loses RPM and airflow drops 30% before the owner notices. We test actual CFM at the discharge, compare to the nameplate, and rebuild or replace the motor assembly based on what the numbers show.
- Guardian Air REME and REME HALO integration with Abatement Technologies central systems: cell degradation in high-RH conditions. The bipolar ionization cell in these add-on units scales with mineral content, and Fairfax’s municipal water chemistry accelerates electrode fouling. We clean the cell with manufacturer-specified solution, check ion output with a handheld meter, and replace cells that read below 2.0 kV rather than selling a whole new unit.
- Abatement Technologies HEPA-AIRE VAC and negative-air machines: filter loading without differential pressure indication. These units rely on pre-filter and HEPA stages that load unevenly in real-world use, especially when pulling through fiberglass-lined ductwork common in 1970s Fairfax split-levels near Mantua. We install a magnehelic gauge where the factory didn’t, photograph the pressure drop across each stage, and change filters based on measured restriction, not calendar date.
- PREDATOR 750 and larger central units: plenum seal failure at the UV access port. The silicone gasket compresses permanently after three to five years of heat cycling, creating a bypass that dumps untreated return air into the supply. We find this with a smoke pencil during our pre-work inspection, document it with the camera, and replace the gasket with high-temp silicone rated for the actual plenum temperature we measure, not generic hardware-store product.
Our Abatement Technologies Air Quality & Sanitizing Process
- 1
Inspection and documentation. We run a borescope through every accessible duct run, photograph each plenum and register boot, and record UV output or ion levels with calibrated meters. The camera goes in first. Then we talk.
- 2
Written scope and price. Tomas Reyes or a senior tech builds the job record with photos attached, names every part and labor item, and delivers a single written price. Haven Standard Clause 1: no work starts without a signed scope.
- 3
Parts decision: OEM or verified aftermarket. For Abatement Technologies UV lamps, we stock OEM quartz sleeves and equivalent USHIO lamps where the OEM is back-ordered. For REME cells, we use only OEM replacement; the warranty requires it and the ion output spec is too tight to trust generics.
- 4
Service execution with continuous documentation. Technicians photograph each step: old part removal, new part installed, torque on electrical connections, UV meter reading at 1 meter, final filter pressure drop. Photos upload to the customer job file in real time.
- 5
Post-service testing and sign-off. We re-measure the parameter that was out of spec, run the system through a complete cycle, and have the homeowner review the before-and-after photo record on a tablet before signing.
- 6
Deliverables and guarantee activation. The customer receives the photo record, the signed scope, and the 365-Day Done Right Promise in writing. If the UV output drops or the odor returns, we make it right.

|---|---|---|
| UV lamp replacement (PREDATOR series) | $180-$340 | Lamp wattage, sleeve condition, access difficulty in tight Fairfax attics |
| REME/REME HALO cell service or replacement | $260-$520 | Cell size, electrode fouling severity, whether wiring harness also degraded |
| Whole-system sanitizing with HEPA-AIRE negative air | $420-$780 | Number of duct runs, pre-existing mold or biofilm, access panel count |
| Portable unit blower motor rebuild (PREDATOR portable) | $240-$400 | Motor size, bearing type, whether housing corrosion requires replacement |
| Differential pressure gauge installation | $140-$220 | Line tap location, gauge size, whether alarm output is included |
Prices include the documented photo record and the 365-Day Done Right Promise. We do not quote per-vent or per-register; the price covers the whole system we scope. Bring a competitor’s written estimate and we’ll deliver a free second opinion, our number next to theirs, no obligation.
Why Fairfax Homeowners Call CleanRun Air Duct Cleaning Fairfax for Abatement Technologies Work
We’ve worked on Abatement Technologies equipment in Fairfax since 2013, including the early PREDATOR 200 series that still runs in homes near the Vienna Metro corridor and the newer integrated systems in Mosaic District townhomes. Our technicians carry OEM and verified aftermarket parts for the full Abatement Technologies line, plus backup knowledge of Lennox, Trane, and Carrier systems for mixed-brand homes. Every tech is background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and identified by name before arrival. The 365-Day Done Right Promise is not a marketing line; it’s a signed document on every job. And the photo record means you don’t have to trust our word about what was in your plenum. You see it.
FAQs
No. As an independent Abatement Technologies service provider, our work does not extend or alter the manufacturer’s warranty on your equipment. We use OEM parts where required to preserve any remaining factory coverage, and we document serial numbers and installation dates so you have what you need for any future warranty claim with Abatement Technologies directly.
We measure UV-C output in microwatts per square centimeter at a fixed distance from the lamp, photograph the meter reading, and include that image in your documented photo record. The reading must meet or exceed the manufacturer’s minimum effective dose for your model. If it doesn’t, we replace the lamp before we leave, at no additional charge.
Replace when repair costs exceed 60% of a comparable new unit installed, or when the equipment is past 12 years and two major components need attention in the same year. We will tell you directly if we reach that threshold during inspection, and we’ll put both numbers in writing so you can decide without pressure. Call (571) 526-0015 if you want us to evaluate what you have.
Most residential jobs finish in three to five hours from arrival to final test. A single UV lamp change takes 60 to 90 minutes if access is straightforward. Whole-system sanitizing with negative-air extraction runs longer because we seal and HEPA-vacuum each duct run individually. We give you a time estimate in writing with the price, before work starts.
The $79 coupon model typically covers a brief vacuum at the register and a spray of deodorizer. It does not include borescope inspection, measured UV output, HEPA-negative-air containment, or a photo record of what was actually inside your ducts. We price the full scope, deliver it in writing, and perform it. If you have a cheaper written quote, bring it; our free second opinion will show you exactly what each line item covers.
