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 New Braunfels: What to Know First
We provide independent Abatement Technologies duct repair and sealing in New Braunfels, with most residential jobs completed in a single scheduled visit and a written price delivered before any work begins. As an independent Abatement Technologies service provider, we are not affiliated with or authorized by the manufacturer, which means we source parts based on what the job actually requires rather than what a dealer program dictates. This page is for homeowners who recognize the Abatement Technologies badge on their air handler or HEPA filtration unit and need the ductwork connected to it sealed, repaired, or rebuilt properly. Call (830) 549-6847 for a free estimate, or bring us any written competitor quote for a free second opinion under Haven Standard Clause 1.
How Abatement Technologies Products Fail - and How We Fix Them
- PREDATOR 750 Series HEPA units with undersized flex duct returns. The 750 moves serious static pressure, and when a New Braunfels installer paired it with cheap 6-inch flex duct in a 2018-2021 build, the suction collapses the inner liner over time. We replace the flex with insulated hard pipe or reinforced flex rated for negative pressure, then balance the return path so the unit does not overwork itself.
- BD2K bed bug decon units with leaky plenum connections. These high-temp systems expand and contract aggressively, which cracks mastic seals at the plenum (the sheet-metal box that distributes air to each duct run). We remove the old brittle sealant, reseat the collar with proper mechanical fasteners, and apply new high-temp mastic rated for Abatement Technologies operating temperatures.
- H2000 series negative air machines with collapsed duct insulation. In New Braunfels attics, the H2000’s long flex runs often have fiberglass insulation that sags after seven to ten summers of 140-degree attic heat. The insulation blocks airflow and the exposed liner tears. We strip the damaged wrap, repair any liner punctures, and reinstall with proper vapor-barrier insulation supported every four feet.
- Portable HEPA units with cross-threaded register boots. Homeowners who move these units room to room sometimes force the 10-inch collar onto an 8-inch register boot, stripping the sheet-metal threads. We fabricate a proper transition piece or replace the boot entirely, sealed with mastic, not tape that will dry out in six months.
- Abatement Technologies central HEPA retrofits with unsealed bypass gaps. When a HEPA unit is added to an existing Carrier or Trane system, the transition collar often leaves a 1/2-inch gap at the air handler cabinet. That gap bypasses the filter entirely. We measure the leakage with a smoke pencil, fabricate a custom sheet-metal closure, and seal it so the HEPA does the job it was bought for.
Our Abatement Technologies Duct Repair & Sealing Process

- 1
Visual and camera inspection. We run a borescope through every accessible duct run and photograph the findings. In New Braunfels homes near the Gruene Historic District, we often find flex duct from the late eighties with debris build-up at the first elbow that the homeowner never knew existed.
- 2
Written scope and price. Before any panel comes off, we deliver a written price with line items for labor, materials, and parts. Haven Standard Clause 1: no work starts without a signature on the price.
- 3
Parts decision. For Abatement Technologies-specific collars, flanges, and gasket kits, we source OEM when the warranty is active and quality aftermarket when the unit is out of coverage. We note the source on the invoice so you can verify it.
- 4
Repair and seal. We repair or replace damaged sections, seal all joints with mastic or foil-backed tape (never duct tape), and support flex duct with proper straps to prevent future sag.
- 5
Pressure test and photo record. We verify seal integrity, then photograph every completed run. The documented photo record is delivered as a standard part of the job file.
- 6
Written guarantee. The 365-Day Done Right Promise goes into writing before we leave. If the seal fails or the repair does not hold, we make it right.

We do not quote per-vent pricing, and we do not offer teaser coupon rates that change once the truck arrives. The price we write is the price you pay.

Why New Braunfels Homeowners Call CleanRun Air Duct Cleaning New Braunfels for Abatement Technologies Work

We have held the same practice since 2013: show the photo first, explain what you’re looking at, then talk about what happens next. Tomas Reyes learned to read ductwork at BOCES Westchester, and that training still shows in how our crews document every job. The 365-Day Done Right Promise is backed in writing, not stated and forgotten. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, which matters because most Abatement Technologies HEPA units are retrofitted onto one of those brands. When the ductwork and the primary HVAC system need to talk to each other correctly, we understand both sides of that conversation.
FAQs
No, provided the work is done by a qualified technician using manufacturer-specified or equivalent parts. As an independent Abatement Technologies service provider, we document every part source and installation method so warranty claims remain valid. If your unit is still under coverage, we flag that before ordering anything and can coordinate with your installing dealer if you prefer. Call (830) 549-6847 to discuss your specific unit.
Every job concludes with a Documented Photo Record of every duct run, before and after, delivered to you as part of the standard job file. We also pressure-test sealed joints where accessible and note the results on your invoice. If a crew cannot show you what they sealed, they did not seal it. Our photo record practice has been in place since our first job in 2013.
Replace when the ductwork is galvanized steel with widespread rust (common in pre-1990 New Braunfels homes), when flex duct is brittle and cracking at multiple points, or when repair costs exceed 60 percent of full replacement. Repair when the damage is localized to one or two runs, the liner is intact, and the Abatement Technologies unit itself is performing well. We give both numbers in writing so you can decide based on math, not pressure.
Most residential jobs take four to six hours. A single register boot or small flex repair might run two to three hours. A full return duct rebuild with hard pipe can take a full day. We schedule specific arrival windows, not “morning or afternoon” vagueness, because your time is worth naming.
Common collars, gaskets, and filter rails are available through our supply chain within two to three business days. Specialized HEPA housing components may take five to seven days. We verify parts availability before writing the price, so you are not surprised by a delay after agreeing to the scope. If your job is urgent, we will tell you honestly whether we can meet your timeline or not.
