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.

How Abatement Technologies Products Fail - and How We Fix Them
- PREDATOR 600 series HEPA units: The flexible duct connections between the PREDATOR’s blower housing and the main trunk line fatigue at the clamp points, especially in Washington’s humidity-cycling climate where summer attic temperatures hit 140°F and winter crawl spaces drop below freezing. We replace the factory flex with reinforced, insulated flex duct rated for the temperature swing, then seal with mastic and mechanical straps rather than zip ties.
- BD2KL negative air machines: The 12-inch inlet collar on older BD2KL units separates from the duct adapter when subjected to repeated negative-pressure cycling above 0.02 inches water column. We fabricate a heavier-gauge collar with a rolled lip and secure it with T-bolt clamps, not the standard worm-gear clamps that ship with the unit.
- ABATEMENT PORTA-PAC systems: The quick-connect fittings on PORTA-PAC supply hoses wear oval after roughly 18 months of regular use in commercial settings around Dupont Circle and Navy Yard. We machine a new brass ferrule in-house or source the OEM fitting, depending on availability, and pressure-test to 150% of operating spec before sign-off.
- CAP600 ceiling air purifiers: The sealed plenum-to-duct gasket on CAP600 units compresses permanently after the first heating season in Washington’s forced-air systems, creating bypass leakage that the homeowner mistakes for filter failure. We remove the compressed gasket, clean the mating surface, and install a reusable silicone gasket rated for 500°F - the fix lasts longer than the factory foam.
- HEPA-AIRE portable scrubbers: The exhaust transition on HEPA-AIRE SA2000 models cracks at the weld seam when the unit is moved frequently between job sites, a common setup in Washington’s renovation-heavy market. We cut out the cracked section, fabricate a replacement from 20-gauge galvanized steel, and seal with fiberglass-reinforced mastic - stronger than the original spot weld.
Our Abatement Technologies Duct Repair & Sealing Process
- 1
Visual and camera inspection. We feed a borescope through every accessible duct run, photograph the condition at each joint and transition, and show the homeowner the images before discussing scope. Show the before photo first. Everything else follows from that.
- 2
Written scope and price. Haven Standard Clause 1: we deliver a single, flat price for the complete repair - no per-vent pricing, no “once we’re in there” escalations. The price covers the work described, period.
- 3
Parts decision with documentation. For Abatement Technologies OEM parts, we note the part number and source on the work order. When we use quality aftermarket equivalents, we document the manufacturer and why it meets or exceeds the original spec - the customer keeps this record.
- 4
Repair and seal. We execute the repair, then seal all joints with mastic or foil tape rated for the application temperature. Metal-to-metal connections get mastic and mesh; flex connections get mechanical clamps plus sealant at the penetration.
- 5
Pressure test and photo record. We pressurize the system and verify no leakage above 5% of design flow at operating pressure. Then we photograph every sealed joint and every repaired section - the after photos join the before photos in the customer’s job record.
- 6
365-Day Done Right Promise in writing. The guarantee is printed, signed, and delivered with the invoice. If the seal fails or the repair doesn’t hold, we return and make it right - no manager approval required.

Washington’s older housing stock - the gravity-fed systems in Capitol Hill rowhouses, the undersized flex runs in 1960s condo conversions near Dupont Circle - often requires more labor than newer construction. We price for the actual work, not a flat-rate guess. Call (240) 363-3380 for a free estimate; we’ll inspect, photograph, and deliver a written price before any work starts.
Why Washington Homeowners Call CleanRun Air Duct Cleaning Washington for Abatement Technologies Work
We’ve been in Washington since 2013, and Tomas Reyes has handled Abatement Technologies configurations that most technicians in this market see once a year if at all - the PREDATOR 600 paired with 1940s galvanized trunk lines, the BD2KL jammed into a Georgetown basement with six inches of clearance. Our crew also services Lennox, Trane, and Carrier systems, which matters when your Abatement Technologies unit is integrated with a mixed-manufacturer HVAC setup and the failure point isn’t obvious.
Every technician is background-checked and uniformed, identified by name before arrival - Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise is printed on every invoice, not buried in a website footer. And the documented photo record, standard on every visit since our first job, lets you verify the work against the quote yourself.
FAQs
No, if the repair is performed by a qualified technician using parts that meet or exceed OEM specifications. As an independent Abatement Technologies service provider, we document every part number and source on your work order, and we never use components that would compromise your remaining warranty coverage. If your unit is still under factory warranty, we’ll flag that before ordering parts and advise accordingly. Call (240) 363-3380 to discuss your specific unit.
Replace when the ductwork shows corrosion through the metal wall, multiple previous repairs, or asbestos-containing insulation that would require abatement - otherwise repair is usually the better value. We make this call based on what the camera shows, not age alone. In Washington, we’ve seen 50-year-old galvanized duct that seals beautifully and 15-year-old flex that needs full replacement due to rodent damage. We’ll show you the photos and explain our recommendation before any price is discussed. Call (240) 363-3380 for a free inspection.
Not always, and not quickly - some PREDATOR and HEPA-AIRE components ship from the factory with lead times of two to three weeks. We maintain relationships with regional distributors and keep common fittings in stock, and when OEM isn’t available, we source quality aftermarket equivalents that we can document and stand behind. We’ll tell you the availability before you commit to the repair, not after. Call (240) 363-3380 to check parts for your model.
Most residential sealing jobs in Washington are completed in four to six hours, with the system back online the same day. Commercial configurations - multiple BD2KL units in a Navy Yard office buildout, for example - may require a full day or scheduling across two visits to minimize downtime. We give you the time estimate in writing with the price, and we don’t start work until you’ve approved both. Call (240) 363-3380 to schedule.
The $79-to-$199 range you see advertised typically covers a visual look and tape on the obvious joints - not a camera inspection, not mastic on every connection, not pressure verification, and not a photo record. We’ve been called in after those jobs to find that the tape failed in the first heating season and the homeowner has no documentation of what was actually done. Our price covers the full repair, documented, with a written guarantee. We also offer a Free Second Opinion on any written estimate - bring us their quote and we’ll put ours next to it, line by line. Call (240) 363-3380.
