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.

AfterTrane Air Duct Cleaning in San Antonio, TX | CleanRun Air Duct Cleaning San Antonio
CleanRun Air Duct Cleaning San Antonio provides independent Trane service across the metro area, from Monte Vista bungalows to Stone Oak subdivisions. The one thing that makes our Trane work here different: we connect Trane’s tight-cabinet, high-velocity design to San Antonio’s specific threats - Cedar Fever pollen loads that hit in December, not spring, and attic duct systems that degrade at 150°F+ every summer. Call (726) 600-7155 for a written estimate before any work starts.
Why San Antonio Residents Choose Us for Trane Service
We work on Trane systems every week. Not occasionally. Every week. XR-series straight-AC units in Lavaca craftsman homes. XV18 variable-speed systems in Alamo Heights renovations. TAM air handlers in 1990s Helotes tract houses with flex return runs that have been cooking in attics since the first Bush administration.
Tomas Reyes, our owner, trained in HVAC systems technology at Queensborough Community College before doing hands-on ductwork across the Northeast. He shifted focus to San Antonio and has logged thousands of hours here. His crew knows the difference between a Trane cabinet seal that looks intact and one that’s pulling 150°F attic air past the filter frame. The camera goes in first. Then we talk. That documented photo record, included on every visit, is how we show you what we found - not tell you.
We are not a Trane dealer. We are not manufacturer-authorized. We are an independent duct cleaning company that stocks OEM Trane filter frames, coil-door gaskets, and cabinet seals alongside aftermarket flex duct, mastic, and insulation from trade-recognized brands: Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman. If your Trane coil or heat exchanger is compromised, we’ll tell you honestly whether cleaning and sealing will buy you years or whether replacement is the smarter spend. We don’t sell equipment. We document what we find and fix what makes sense to fix.
Common Trane Air Duct Cleaning Problems We Solve in San Antonio
- Spine Fin coil clogging on XR-series units. Trane’s all-aluminum Spine Fin condenser coils on XR13, XR14, and XR16 units clog with caliche and limestone dust pushed in by southwesterly wind events. During San Antonio’s June-through-September 100°F+ stretches, this drives high head pressure and longer runtimes. We clean the coil face and check cabinet intake seals - not with a garden hose, but with controlled negative-pressure extraction and manufacturer-compatible foaming agents.
- Return-plenum leaks on variable-speed XV systems. Trane TAM and S-Series air handlers on XV18 and XV20i systems pull enormous return-air volumes. A small leak around the cabinet in a 150°F attic carries more unfiltered attic dust into the coil than a comparable single-stage system would. We find these with smoke pencils and seal them with mastic and OEM-compatible gasket material.
- Broken flex-duct seams at the air handler collar. Trane’s tight cabinet and coil-door gasket design means that if the return duct seal at the air handler is broken, unfiltered air bypasses the filter frame entirely. This is a common finding in 1970s-90s Stone Oak and Helotes tract homes with original flex return runs. We HEPA-vacuum the debris and reseal with reinforced mastic.
- Blower wheel and coil face coating during Cedar Fever season. Trane heat pump systems in San Antonio recirculate Ashe juniper pollen through the return grille on every heating cycle from December to February. The pollen coats the blower wheel and evaporator coil face, reducing airflow and throwing off charge readings. We clean both components and verify post-cleaning airflow with a manometer.
- Collapsed flex duct in north-side attics. San Antonio’s 150°F+ attic temperatures degrade flex-duct insulation and support straps. In Stone Oak and the Helotes corridor, we regularly find 10-foot sections of return duct that have sagged or collapsed, creating turbulence that drops static pressure and lets debris accumulate at low points.
BeforeAfterTrane Service in San Antonio: What Local Conditions Mean for Your Equipment
San Antonio sits at the southern edge of the Edwards Plateau - ground zero for Ashe juniper, locally called “mountain cedar.” The pollen counts here in December through February are some of the highest recorded anywhere in the US. This is not a spring-allergy market. It’s a winter-allergy market, and that changes everything about how Trane duct systems behave.
Most Trane owners assume their ducts are cleanest when the AC shuts off in October. The opposite is true here. Trane heat pump and gas-furnace systems pull that yellow-green pollen through return grilles on every heating cycle, coating duct interiors and recirculating allergens when the family is sleeping with windows closed. A Trane XV variable-speed system running low-stage heat for 18 hours a day in January moves more total air volume than it does in July, when the thermostat satisfies quickly and cycles off. The worst duct contamination of the year often happens after the AC season ends.
A homeowner in the Helotes corridor with a Trane XV18 called us in January because the family was waking up congested every morning even though the AC hadn’t run in weeks. Our tech pulled the return grille and found the flex return run caked in yellow-green Ashe juniper pollen, then found a torn flex seam at the Trane air handler cabinet that was pulling attic dust straight past the filter. We HEPA-vacuumed the return and supply runs, cleaned the evaporator coil face and blower wheel, and mastic-sealed the air handler collar as part of our Dryer Vent Cleaning in San Antonio. Runtime airflow came back up. The morning congestion complaints stopped.
This winter demand spike doesn’t exist in Houston, Dallas, or most other major Texas markets. If you’re a Trane owner in San Antonio, your ducts need attention in January, not April.
Trane Models & Products We Service in San Antonio
We clean and service the full Trane residential line, including:
- XR series: XR13, XR14, XR14i, XR16, and XR16i single-stage and two-stage outdoor units - the workhorses of San Antonio’s 1990s-2010s housing stock, especially in Monte Vista, Lavaca, and Terrell Hills renovations where the outdoor unit was upgraded but the ductwork wasn’t.
- XR heat pumps: XR15 and XR17 models common in north-side subdivisions built during the 2000s energy-efficiency push.
- XV variable-speed systems: XV18 and XV20i communicating systems with matching TAM or S-Series variable-speed air handlers - increasingly found in Stone Oak, Alamo Heights, and Castle Hills homes built or renovated after 2015.
- Legacy air handlers: Older Trane TAM4, TAM7, and TAM9 units, plus S-Series cabinets, where cabinet seal degradation is the primary failure mode we address.
We stock OEM Trane filter frames, coil-door gaskets, and cabinet seals for same-day installation. For flex duct, mastic, and insulation replacement, we use quality aftermarket materials rated for 150°F+ attic exposure. If your Trane system needs a part we don’t carry, we source it next-day from San Antonio HVAC supply houses - no waiting on Dallas or Houston distribution.

FAQs - Trane Air Duct Cleaning in San Antonio
Yes. Ashe juniper pollen from December through February coats duct interiors, blower wheels, and evaporator coil faces in Trane systems that run heat pump or furnace cycles continuously. The pollen is oily and adheres to metal surfaces more stubbornly than household dust. We document this with before-and-after photos on every winter job. Call (726) 600-7155 for an exact quote - estimates are free.
Constant low-stage operation moves more total air volume over time than a single-stage system that cycles on and off. If your return ducts have leaks or your filter frame has gaps, the XV system pulls more unfiltered attic air through those openings. We inspect Trane variable-speed systems for cabinet seal integrity as a standard step. Call (726) 600-7155 for an exact quote - estimates are free.
We clean Spine Fin coils with controlled foaming agents and low-pressure rinsing, followed by negative-pressure drying. Replacement is only necessary if the aluminum fins are corroded through or the copper tubing is compromised. We photograph the coil condition and show you before writing any scope. Call (726) 600-7155 for an exact quote - estimates are free.
We provide a written invoice with line-item scope, before-and-after photos of every duct run, and a 365-Day Done Right Promise certificate. Property managers in Converse, Live Oak, and Universal City have accepted this documentation for hundreds of our PCS turnover jobs. The photo record proves the work happened; the written warranty proves it was done to standard.
Trane’s cabinet design is tighter than most brands, with a coil-door gasket that creates a pressure boundary. If the return duct seal at the cabinet collar is broken, unfiltered air bypasses the filter frame entirely - there’s no secondary path for it to get filtered later. This is a Trane-specific failure mode we check on every job.
