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 San Antonio: What to Know First
We provide independent Abatement Technologies duct repair and sealing in San Antonio, with most repairs scheduled within a few business days and completed in a single visit. A typical Abatement Technologies system repair runs $340-$780 depending on whether we’re sealing accessible joints or replacing collapsed flex runs behind drywall. Every job starts with a written price before any panel comes off, and every duct run is photographed before and after.
This page is for San Antonio homeowners who already know they have Abatement Technologies equipment and want a technician who recognizes the difference between a PREDATOR 600 series negative air machine and a HEPA-AIRE portable, and who won’t treat your ductwork like generic tin. Call (726) 600-7155 for a written estimate. No “call for a quote” here - Haven Standard Clause 1.
How Abatement Technologies Products Fail - and How We Fix Them
- PREDATOR 600 series negative air machines: The flexible intake hoses on these units harden in San Antonio’s heat after three to four years, developing cracks at the barbed fittings that pull false air and drop negative pressure. We replace with reinforced, heat-rated flex duct and seal with mastic, not tape, since tape adhesive degrades fast in attics that hit 140°F in July.
- HEPA-AIRE H5000 portable scrubbers: The 12-inch diameter flex collar on the exhaust side fatigues at the clamp point from repeated repositioning during remodel work. We see this in Alamo Heights renovation jobs where the unit’s moved room to room. Our fix is a metalized flex section with a double-clamp mechanical seal, plus a photo of the pressure test.
- Abatement Technologies PAS2400 pre-filters in integrated systems: When these clog in high-pollen San Antonio springs, the backup pressure can separate mastic seals at the plenum inlet. The camera showed a half-inch mat of debris at the plenum inlet on a Stone Oak job last March. We clean the filter track, reseal with fiber-reinforced mastic, and photograph the seal cure.
- Flexible duct runs on Abatement Technologies source-capture setups: The internal wire helix corrodes where condensation pools in unconditioned crawl spaces common in older Terrell Hills homes. We sleeve the damaged section with new flex or switch to solid metal where clearance allows, depending on what the photo record shows.
- Abatement Technologies DUCT-PRO adhesive gaskets: These OEM gaskets shrink faster than aftermarket silicone-composite alternatives in dry attic conditions. We stock both and explain the trade-off: OEM maintains any active warranty, quality aftermarket lasts longer in San Antonio’s heat. The customer chooses after seeing the written price for each.

Why San Antonio Homeowners Call CleanRun Air Duct Cleaning San Antonio for Abatement Technologies Work
We’ve logged thousands of hours in San Antonio homes since 2013, including tract homes near Stone Oak where flex duct collapses and dust accumulation are textbook examples of what we document on every job. Tomas Reyes, our owner, trained in HVAC systems technology at Queensborough Community College and spent years doing hands-on ductwork across the Northeast before building CleanRun’s San Antonio operation. He keeps a folded photo of his late father’s woodworking shop tacked inside his work van - a reminder that craftsmanship shows in what you leave behind, not what you say.
Our technicians also service Lennox, Trane, and Carrier systems, so when your Abatement Technologies equipment interfaces with a mixed-brand HVAC setup, we understand the integration points other contractors miss. Every job includes the Documented Photo Record, the written price before work starts, and the 365-Day Done Right Promise backed in writing. Equipment on our trucks includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - brands you can verify independently.
FAQs
Independent repair does not automatically void the warranty, but using non-OEM parts on certain components can. We check your unit’s serial and manufacture date to determine warranty status before recommending OEM versus quality aftermarket parts, and we document that choice in writing. Call (726) 600-7155 if you want us to review your warranty terms alongside the repair estimate.
You receive a Documented Photo Record of every duct run, before and after, as a standard deliverable on every CleanRun job. We also perform a pressure differential test on sealed systems and record the result. The photo record is dated, geotagged, and delivered to you - not held on our servers as a favor.
Repair makes sense when the damage is localized to accessible sections and the unit’s pressure specs still meet manufacturer standards. Replacement is the better call when multiple flex runs have failed, the plenum is corroded, or repair costs exceed 60 percent of a new comparable system’s installed price. We give you both numbers in writing and let the math decide.
Most single-section repairs are completed in two to four hours. Integrated system reseals on larger Abatement Technologies negative air setups can take a full day. We schedule by the job, not by the hour, so the crew stays until the pressure test passes and the photo record is complete.
We stock common Abatement Technologies flex collars, gaskets, and mastic-compatible sealants on our trucks. Specialty components for older HEPA-AIRE or DUCT-PRO series units typically arrive within two to three business days from regional distributors. If your job requires a wait, we tell you before you sign anything - no surprises after the written price is approved.
