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 Katy: What to Know First
CleanRun Air Duct Cleaning Katy provides independent Abatement Technologies duct repair & sealing in Katy, typically completed in a single scheduled visit with a written price delivered before any panel comes off. Most Abatement Technologies systems we see in Katy homes - particularly the HEPA-AIRE and PREDATOR series common in post-2017 builds near Cane Island and Elyson - need sealing at flex-to-metal junctions or mastic repair at the plenum connection, not full replacement. We quote by the scope of the actual damage, not the square footage on your listing.
This page is for Abatement Technologies owners in Katy who’ve noticed uneven airflow, utility spikes, or the telltale whistling that starts when Houston’s summer humidity swells the duct seams. Call (346) 666-7165 for a free estimate with a written price before we start.
How Abatement Technologies Products Fail - and How We Fix Them
- HEPA-AIRE SAH2 and SAH4 series: flex duct collapse at the takeoff collar. The corrugated flex on these portable negative-air units fatigues where it meets the rigid trunk, especially in Katy attics where summer temperatures exceed 140°F for months. We cut back to sound material, install a reinforced takeoff with metal-backed tape, and seal with mastic rated for the temperature swing.
- PREDATOR 750 and 1000 units: gasket deterioration at the filter housing seal. The foam gaskets on these high-CFM machines compress permanently after two to three years of cycling, pulling unfiltered attic air past the repair zone. We replace with silicone-impregnated closed-cell gaskets that outlast OEM foam in Houston humidity, documented in the photo record.
- Abatement Technologies PAS2400 and PAS3600 portable air scrubbers: duct adapter thread damage from cross-threading. These aluminum adapters strip easily during filter changes. We helicoil or replace with steel-threaded adapters, depending on wall thickness, and torque to manufacturer spec so the next filter change doesn’t repeat the damage.
- HEPA-AIRE Guardian negative air machines: vibration cracks in the secondary plenum. The polymer plenum on Guardian units develops stress fractures near the blower mount after sustained operation. We fiberglass-wrap and mastic-seal viable cracks; replace the plenum section when the crack propagates to the flange. The camera shows the difference before we quote either path.
- Abatement Technologies ducting in Energy Star homes near Grand Lakes: thermal expansion separation at mastic joints. Katy clay soil shifts; the house breathes; the mastic doesn’t. We remove failed mastic back to sound substrate, apply fiber-reinforced water-based mastic in two coats, and document the cure time before pressurizing. This is standard on homes built 2015-2020 where the original sealant was applied in a single pass.
Our Abatement Technologies Duct Repair & Sealing Process
- 1
Photo-first inspection. We pull the camera before touching a single register. The before photo does the talking. Everything after that is just paperwork.
- 2
Written scope and price. Haven Standard Clause 1: written price delivered before any work starts, based on what we found, not what we hope to sell. No exceptions.
- 3
Parts decision. OEM Abatement Technologies gaskets and adapters when available; quality aftermarket when lead times exceed five business days or when the aftermarket part exceeds OEM spec. We document the choice in writing.
- 4
Repair and seal. Mastic application, mechanical fastening, or component replacement per manufacturer torque and cure specifications. We run the unit through a full cycle before declaring the job complete.
- 5
Pressure verification and photo record. Post-repair airflow measured at the register, compared to pre-repair baseline. Before-and-after photos of every duct run delivered as standard.
- 6
365-Day Done Right Promise in writing. If the seal fails or the repair doesn’t hold, we make it right. Not a policy subject to manager approval. A written guarantee.

Why Katy Homeowners Call CleanRun Air Duct Cleaning Katy for Abatement Technologies Work
We’ve worked on Abatement Technologies equipment in Katy since 2013, including a run of older ranch-style homes near LaCenterra at Cinco Ranch where the ductwork tells you more about the house’s history than the seller’s disclosure ever will. Tomas Reyes and our technicians know the difference between a HEPA-AIRE flex failure and a PREDATOR gasket issue before the ladder comes off the truck.
We’re also fluent in Lennox, Trane, and Carrier duct configurations - critical when your Abatement Technologies air scrubber ties into a mixed-manufacturer HVAC system, which is standard in Katy builds from 2015 onward. Haven Standard Clause 3: Verified Crews means background-checked, uniformed technicians identified by name before arrival. The 365-Day Done Right Promise and full Documented Photo Record are included on every visit, not sold as add-ons.
FAQs
No, independent repair does not automatically void the warranty, but using non-OEM parts can limit coverage on the specific component replaced. We source OEM Abatement Technologies gaskets and adapters when available, document part numbers in your job record, and flag any warranty-sensitive decisions in writing before work starts. Call (346) 666-7165 if you need help reading your warranty language.
You receive a Documented Photo Record of every duct run, before and after, as a standard deliverable on every CleanRun job. We also measure register airflow pre- and post-repair and record the readings in your written job summary. If the numbers don’t move, we don’t invoice.
Replace when flex duct shows multiple punctures, permanent crush, or mold penetration visible on camera; repair when the damage is localized to collars, joints, or gasket surfaces. We quote both paths when the line is close, and we don’t recommend replacement we can’t justify with documentation.
Common gaskets, adapters, and flex sections are typically available within three to five business days through regional HVAC distributors. For older HEPA-AIRE portable units, we maintain relationships with salvage suppliers and fabricate adapter solutions when OEM parts are discontinued. We confirm parts availability before quoting a start date.
Most properly installed Abatement Technologies duct systems need inspection at five to seven years in Houston’s climate, with resealing at joints every ten to twelve years. Homes near construction zones or with frequent filter changes may need earlier attention due to vibration or handling stress. We don’t sell maintenance contracts; we document what we see and let you decide.
