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.

AfterFast, Reliable Air Duct Cleaning Across San Antonio
Air duct cleaning for a typical San Antonio home runs $350-$650 for a full system, with rural properties and outbuilding systems often landing in the $550-$900 range depending on access and contamination level. Our crews dispatch from the San Antonio office and carry negative-pressure HEPA extraction rigs, Rotobrush mechanical agitation systems, and Nikro portable vacuums built for the caliche dust and cedar pollen load this region produces. Call (830) 402-5110 and we’ll answer live, schedule a visit, and deliver a written price before any panel comes off.
San Antonio’s not a generic market. The Hill Country’s Ashe juniper belt ends right here, and the caliche limestone terrain generates a particulate mix that flat-terrain cities simply don’t face. Our technicians train on that specific combination, and our equipment roster reflects it.
Why CleanRun Air Duct Cleaning Schertz Is San Antonio’s Preferred Air Duct Cleaning Company
We’ve served San Antonio since 2013, completing over 52,000 jobs with a written price delivered before work started every single time. That number includes thousands of homes in the rural fringe and northwest-side subdivisions where caliche roads and thermal-stressed flex ducts create conditions most metro-only crews haven’t encountered.
Our San Antonio customers receive the same deliverable on every visit: a Documented Photo Record showing the inside of every duct run before and after source removal. No manager-approval games. The 365-Day Done Right Promise is printed on the work order, not buried in a website footer.
Haven Standard Clause 1 requires that written price. Haven Standard Clause 3, Verified Crews, means background-checked, uniformed technicians identified by name before arrival. Tomas Reyes built this standard into the company’s first job in 2013, and it hasn’t changed.
Our San Antonio office coordinates dispatch and scheduling. Crews carry local knowledge: which northwest-side subdivisions built during the 1980s-2000s tract boom are hitting 20-40 years on original flex-duct systems, how cedar fever season (December-February) hits return-air systems after summer thermal cycling has already loosened joints, and why a 5-year cleaning interval written for a Houston suburb will clog an air handler here in half that time.
Our Air Duct Cleaning Services in San Antonio
Residential Duct Cleaning
San Antonio’s slab-on-grade stock, especially the north and northwest-side inventory from the 1980s-2000s boom, puts flex ducts through attic temperatures exceeding 150°F for seven months straight. That thermal cycling expands and contracts joints until they fail. Our residential cleaning starts with a video inspection of every run, source removal under negative pressure with HEPA filtration, and documentation of any separations or collapsed sections we find. The photo record goes to the homeowner before we pack up.
Commercial Duct Cleaning
San Antonio commercial systems face the same cedar pollen and caliche load as residences, but with higher static pressure and more complex zoning. We clean supply and return plenums (the main distribution boxes), branch runs to each zone, and registers (the vent covers where air enters the room), documenting each stage. Our equipment includes Abatement Technologies portable HEPA units for occupied-space work, and we schedule around your hours, not ours.
Supply Duct Cleaning
Supply ducts push conditioned air to your registers. In San Antonio, these runs often carry the evidence of summer thermal damage: collapsed flex, separated boots, or gaps pulling raw 150°F attic air into the stream meant for your living room. We photograph every supply run before agitation and extraction, so you see whether the problem is debris or structural failure. Sometimes it’s both.
Return Duct Cleaning
Return ducts pull air back to the air handler for reconditioning. In San Antonio’s rural fringe, these are the first point of contact for caliche road dust and cedar pollen, and they load heavy. We ran a full system cleaning on a slab-on-grade home off a caliche road outside Helotes, where the return cans were packed with a gray caliche-and-cedar-pollen mat and our camera inspection found a flex run pulled half off its boot collar, pulling raw attic air into the supply side. After source removal under negative pressure with HEPA filtration and re-securing the flex at the collar with mastic and a new zip tie, static pressure at the air handler dropped and the homeowner’s winter cedar complaints eased noticeably. We also cleared the detached shop’s separate supply and return ducts, which had never been touched since the building went up.
Full System Cleaning
The complete package: every supply run, every return run, plenums, registers, and the air handler cabinet. For San Antonio rural properties with wood heat and outbuilding systems, this is the only scope that addresses the full contamination cycle. Ash and fine soot settle through returns during heating season; the first spring AC cycle redistributes it everywhere. A partial cleaning leaves that reservoir in place.
Video Inspection
Every job starts here. We run a camera through the ductwork before touching equipment, so you see what we see: debris depth, joint condition, collapsed sections, or gaps pulling attic air. The footage becomes part of the Documented Photo Record. In San Antonio’s older flex-duct inventory, this step often reveals structural problems that explain why the house never feels comfortable regardless of thermostat setting.

Our crews deploy professional-grade equipment customers can verify independently: Rotobrush mechanical agitation brushes for debris breakup, Nikro and Abatement Technologies negative-pressure HEPA extraction systems for source removal, and Honeywell and Aprilaire air quality components where filtration upgrades make sense. Guardsman protective treatments are available for duct liner restoration where thermal degradation has compromised the surface. We don’t stock mystery tools or rebrand consumer vacuums. Every machine is traceable to its manufacturer, and every technician trains on its proper use before entering a San Antonio home.
Common Air Duct Cleaning Problems We See in San Antonio Homes
- Cedar pollen infiltration through failed joints. San Antonio sits at the base of the Hill Country’s Ashe juniper belt. During December-February, extraordinarily fine cedar pollen infiltrates return-air systems through any gap or ill-sealed register and recirculates through living spaces. Technicians working northwest-side subdivisions near the Balcones Escarpment - areas like Helotes and Leon Valley - routinely find flex ducts that have partially collapsed or pulled off boot collars after years of thermal stress, meaning a “duct cleaning” job often uncovers system leaks that have been drawing raw attic air and cedar pollen directly into the supply stream.
- Caliche dust loading on rural properties. San Antonio’s rural fringe sits downwind of unpaved caliche roads and open ranch land, so return-air systems in outlying homes load with coarse limestone dust plus Ashe juniper pollen - a dual particulate load that flat-terrain, paved-suburb cities don’t produce. Because those properties often run wood heat or a shop/outbuilding system alongside the house, duct cleaning intervals run 2-3 years instead of the metro-average 3-5.
- Wood heat soot redistribution. Rural properties using wood heat let ash and fine soot settle through the return ducts in the off-season, then the first spring AC cycle redistributes it through every register. A standard cleaning that ignores the return-side reservoir leaves this problem intact.
- Skipped branch runs on long service drives. Long service drives to outlying ranch properties tempt crews to skip full negative pressure setups and camera inspection, leaving the far-end branch runs and outbuilding systems uncleaned. Our Haven Standard Clause 1 written scope specifies every run to be cleaned before the truck leaves; the photo record proves it happened.

FAQs - Air Duct Cleaning in San Antonio
Every 2-3 years, not the 3-5 year metro standard. The caliche road dust and cedar pollen dual load fills returns faster, and wood heat adds soot that settles through the system in off-months. Unpaved caliche roads load returns fast; homeowners who keep a 5-year metro interval end up with a clogged air handler, dirty blower motor, and dust-coated coils well before that. Call (830) 402-5110 and we’ll inspect to set an interval based on your actual conditions.
Yes. Ash and fine soot settle through return ducts during heating season, then the first spring AC cycle redistributes it through every register. A standard cleaning that ignores the return-side reservoir leaves this problem intact. Our full system scope includes return plenum and trunk cleaning specifically to capture this reservoir. The photo record shows what came out.
It pulls raw attic air - 150°F in summer, pollen-laden in winter - directly into your supply stream, bypassing filtration entirely. In San Antonio’s northwest-side subdivisions near the Balcones Escarpment, we find this regularly on 20-40 year old flex-duct systems. Static pressure drops, rooms don’t condition evenly, and cedar pollen enters living spaces unfiltered. We re-secure with mastic and mechanical fasteners, then verify with post-repair camera footage.
They run on separate air handlers, draw from separate return paths, and accumulate separate contamination loads - often metalworking dust, vehicle exhaust particulate, or agricultural debris that doesn’t belong in the house system. The Helotes job we described had a shop system untouched since construction; its returns were packed with a different debris profile entirely. Cleaning the house and ignoring the shop leaves a contamination source active on the same property.
It removes the reservoir of cedar pollen accumulated in ductwork, which helps if your system has been recirculating prior-season pollen through gaps or failed joints. It does not block new pollen from entering through windows, doors, or fresh-air intakes. The most effective combination: source removal cleaning plus sealing gaps we find during inspection, plus verifying that your filtration is rated for the particle size cedar pollen represents. We document all three during the visit.
