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 Duct Repair & Sealing in Round Rock: What to Know First
We provide independent Abatement Technologies duct repair and sealing in Round Rock, with most jobs scheduled within a few business days and completed in a single visit. A typical Abatement Technologies flex duct repair or metal trunk seal runs $280-$620 depending on accessibility and material, and we deliver that number in writing before any panel comes off. This page is for homeowners who already know they own Abatement Technologies air handling equipment and need someone who understands how those specific plenum connections and collar assemblies wear out in Central Texas heat. Call (737) 259-5752 for a free estimate, or bring us a competitor’s written quote for a free second opinion under Haven Standard Clause 1.
How Abatement Technologies Products Fail - and How We Fix Them
- PREDATOR 750/800 Series: Collar separation at the main trunk. The pressed-metal collar connections on these larger residential units fatigue from thermal cycling, especially in Round Rock attics where summer roof deck temperatures exceed 140°F. We find the gap with a borescope, then cut back to solid metal and re-seat with a reinforced draw-band and mastic sealant rated for the operating temperature range.
- BD2K Series: Flex duct inner liner collapse at the first elbow. The BD2K’s compact plenum design creates a sharp turn that stresses the flex duct where it exits the air handler. After a few seasons, the inner liner tears and the insulation sleeve sags, creating a bypass that dumps conditioned air into the attic. We replace the damaged section with a longer-radius sweep and support it with a metal hanger every four feet.
- CAP600 Series: Mastic sealant degradation on horizontal runs. The CAP600’s lower static pressure profile means longer run times, and the constant airflow vibration slowly cracks the original mastic at longitudinal seams. Our crew strips the old mastic to bare metal, primes with HVAC-specific sealant base, and applies two coats of fiber-reinforced mastic - not the bucket-grade stuff from the hardware store.
- HEPA-AIRE PAS2400: Filter box gasket failure causing negative pressure leaks. The PAS2400’s high-efficiency filter housing uses a foam gasket that compresses permanently after three to five years. We see this in Teravista homes where the unit runs hard through cedar pollen season. The fix is a factory-spec replacement gasket or, when the flange is warped, a custom-fabricated silicone seal.
- Portable units (PAS600, PAS1200): Duct adapter cracks from repeated handling. These units move between job sites or rooms, and the plastic duct adapters fatigue at the stress risers. We stock reinforced aftermarket adapters that outlast the OEM part, or we can fabricate a metal transition when the application demands it.
Our Abatement Technologies Duct Repair & Sealing Process

- 1
Camera inspection before quote. Tomas Reyes runs a borescope through every accessible duct run to document the failure. The camera goes in first. Then we talk.
- 2
Written price delivered on site. Haven Standard Clause 1: the scope and price are written and signed before work begins. No exceptions.
- 3
Parts decision: OEM or verified aftermarket. For Abatement Technologies equipment, we source factory collars and gaskets when available. When lead times stretch past what a homeowner can reasonably wait, we use aftermarket parts that meet or exceed the original spec, documented in the job record.
- 4
Repair execution with photo documentation. Every step is photographed: the damaged section, the repair in progress, the finished joint. These images are delivered with the invoice.
- 5
Pressure test and airflow verification. We pressurize the system and check static pressure at the unit against Abatement Technologies specifications. If the numbers don’t match, we reopen the joint.
- 6
Cleanup, photo record delivery, and warranty registration. The 365-Day Done Right Promise is printed on the final document, with Tomas Reyes’s direct contact for any callback.

Why Round Rock Homeowners Call CleanRun Air Duct Cleaning Round Rock for Abatement Technologies Work

We’ve worked on Abatement Technologies equipment in Round Rock since 2013, including jobs in Stone Oak Ranch where new construction flex duct was already separating at the plenum, and in older Teravista homes where the original mastic had turned to dust. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they carry the full equipment roster - Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - so a multi-brand household doesn’t need multiple contractors. The 365-Day Done Right Promise means if a seal fails or a collar loosens, we return and fix it at no charge, documented in writing on every job, not subject to manager approval. We also service Lennox, Trane, and Carrier systems for homeowners with mixed equipment.
FAQs
No, properly performed duct sealing or flex duct repair does not void the equipment warranty, though modifications to the air handler cabinet itself can. As an independent Abatement Technologies service provider, we document every repair with before-and-after photos and parts specifications so warranty coverage remains intact for factory defects. Call (737) 259-5752 if you need help interpreting your warranty documents.
Most common Abatement Technologies collars, gaskets, and adapters are available within three to five business days through our distributors. For older or specialized units, we verify availability before scheduling so you’re not waiting on a truck that never shows. We also keep reinforced aftermarket equivalents in stock for urgent situations.
Repair is the right call when the damage is localized to one or two runs and the air handler itself is within its service life. Replacement makes more sense when multiple trunk lines show failure, the plenum is rusted through, or the equipment is past fifteen years and due for upgrade either way. We’ll show you the camera footage and give you both numbers in writing.
Every CleanRun job includes a Documented Photo Record of every duct run, before and after, delivered with your invoice. We also provide static pressure readings taken at the unit. If you want to verify independently, hold a smoke pencil or thin tissue near the repaired joint while the blower runs - no movement means no leak.
Yes, we repair and seal the duct adapters and flex connections on PAS600 and PAS1200 portable negative air machines, common in restoration work around Round Rock. The adapter cracks and hose wear are different failure modes than fixed HVAC ductwork, and we stock the reinforced replacements that hold up to repeated handling.
