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 Sealing & Repair: The Plano Owner’s Guide
Abatement Technologies duct sealing and repair in Plano typically runs $340-$780 for a complete system, depending on linear footage and accessibility, and we stock the compatible materials on our trucks for jobs scheduled across Collin County. Most Plano homeowners discover the issue when rooms stop heating or cooling evenly, or when a utility bill jumps 20-30% without explanation. The sealing compound or mechanical fastener has usually degraded past the point where tape or consumer-grade mastic can recover it.
Tomas Reyes started CleanRun in 2013 with one habit: photograph the inside of the duct run before quoting a price. The customer sees what he sees. “Show the photo first. Talk second.” That practice still governs every Plano job we run.
Which Abatement Technologies Models This Applies To
Abatement Technologies manufactures negative-air machines, HEPA filtration systems, and portable containment units for remediation and restoration work. Their duct sealing components appear most often in the PREDATOR and CAPTURE series portable units, plus the fixed HEPA-AIRE installations found in some larger Plano homes built during the 2015-2020 construction wave near Windhaven Parkway and the Legacy West corridor.
To identify your specific part, check the equipment label for the model prefix: PRED units use a different gasket profile than CAP series machines, and the HEPA-AIRE fixed systems require fire-rated sealing tape that meets Collin County amendment R-302.2 for penetrations between conditioned and unconditioned spaces. The OEM Abatement Technologies gasket runs roughly 40% above quality aftermarket equivalents from Guardsman, which we also carry. For restoration-grade containment where air leakage compromises the work zone, we typically recommend OEM. For standard residential duct sealing where the goal is efficiency recovery, the Guardsman equivalent meets the same CFM-loss specs at a lower installed price.
Signs Your Abatement Technologies Duct Sealing & Repair Is Failing

- Uneven temperatures room to room. When sealing compound at plenum joints (the main distribution box where air splits to individual duct runs) cracks or pulls away, the system loses pressure before conditioned air reaches the register. We see this most in Plano’s older ranch homes near the Shops at Legacy, where original flex duct from the early 1990s has hardened and shifted at the connection points.
- Dust accumulation at register edges or ceiling stains. Failed seals pull attic air into the return side, carrying fiberglass particles and North Texas pollen that bypass the filter. The camera often shows a 3-inch debris build-up at the first elbow.
- Whistling or rushing noise from walls or ceiling. Air velocity increases at the leak point as the system tries to maintain setpoint. In summer, when Plano attic temperatures exceed 140°F, the thermal expansion makes these gaps audible.
- Utility bill spikes without thermostat changes. A 15% duct leakage rate, common with degraded Abatement Technologies gaskets in fixed installations, forces the HVAC system to run 20-30% longer to hit target temperature.
- Musty odor when the system cycles on. Negative pressure at the return leak pulls humidity and microbial growth from unconditioned spaces. This is the symptom that usually prompts the call, because the smell arrives before the bill spike registers.

AfterReplacement Cost & What’s Included
| Scope | Typical Range in Plano |
|---|---|
| Single register seal (accessible) | $180-$260 |
| Plenum reseal (partial, up to 4 joints) | $280-$420 |
| Full system seal, Abatement Technologies compatible | $340-$780 |
| Plenum replacement + seal (galvanized, R-6 insulated) | $580-$940 |
The range reflects linear footage, attic accessibility, and whether we are resealing existing metal or replacing degraded flex duct. Every quote under Haven Standard Clause 1 is written and agreed before work starts. The price includes negative-pressure extraction during the repair (so debris does not enter living space), the Documented Photo Record of every duct run before and after, and the 365-Day Done Right Promise backed in writing. We do not quote per-vent pricing; one flat price per system, period.
DIY or Call Us?

A homeowner can safely inspect visible ductwork in an attic or crawl space for obvious gaps, disconnected flex, or deteriorated tape. Look for shiny spots where factory mastic has turned to dust, or collars that separate when lightly tugged.
Where DIY goes wrong: sealing a leak without addressing the underlying cause, usually duct sag or improper support spacing. Consumer-grade foil tape fails within two Plano summers because it cannot handle the thermal cycling. More critically, working in attics during June through September presents genuine heat-stress risk, and disturbed insulation may contain asbestos in pre-1985 Plano construction. For Abatement Technologies fixed HEPA installations, any seal affecting the containment barrier requires documentation for insurance or remediation compliance.
We carry Abatement Technologies-compatible gaskets, Guardsman aftermarket equivalents, and fire-rated sealing tape on every truck. Call (469) 452-7766 for a written estimate with no obligation.
FAQs
Properly installed professional-grade sealing lasts 10-15 years in North Texas, though attic temperatures above 130°F for extended periods can shorten that to 8-10 years. The thermal expansion coefficient of galvanized plenum metal versus flexible duct creates micro-movement every cycle. Call (469) 452-7766 and we will photograph your current condition and give you a realistic lifespan estimate based on what we find.
Surface re-taping is possible if the underlying gasket is intact and the joint is accessible, but it is usually a short-term fix. We have found that “repaired” seals in Plano homes fail again within 18-24 months because the original adhesive layer has degraded. Our written quote will note whether repair or replacement is the appropriate scope, with the price for each.
Most residential Abatement Technologies-compatible sealing jobs run 2.5 to 4 hours for a single system, including setup, photography, and cleanup. Full plenum replacement or jobs in tight Legacy West attics may extend to a full day. We schedule with a two-hour arrival window and text the technician’s name and photo before dispatch.
We stock Abatement Technologies-compatible gaskets, Guardsman aftermarket equivalents, fire-rated tape, and galvanized plenum materials on every service vehicle. For obsolete PREDATOR series components, we source overnight from our Dallas-Fort Worth supplier network. If we cannot complete the job on the scheduled day due to a parts availability issue, we reschedule at no additional trip charge.
CleanRun Duct Repair & Cleaning is independently owned and operated under the Haven Standard. We are not affiliated with Abatement Technologies, though we install and service equipment compatible with their specifications. We also stock parts for Lennox, Trane, and Carrier systems.
