AfterFast, Reliable Air Duct Cleaning Across San Antonio
Air duct cleaning in San Antonio typically runs $350 – $650 for a full residential system, with most jobs completed in a single visit. We dispatch crews from our San Antonio office, and we regularly serve homes from Alamo Heights to Helotes with arrival windows we keep.
San Antonio’s combination of heavy caliche dust, live oak pollen, and decades of original flex ductwork creates problems that don’t respond to a simple vacuum job. Our Air Duct Cleaning team finds sagging runs packed with debris, disconnected collars dumping conditioned air into attics, and rodent damage hidden behind insulation in the older neighborhoods where much of this city’s housing stock was built. We price every job in writing before touching the system, and every repair carries our 365-Day Done Right Promise. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is San Antonio’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our San Antonio operation runs on The Garrison Standard: arrive inside the quoted window, price in writing before work starts, complete the job by the book, and leave the site clean. That standard matters here because San Antonio’s pre-1990s housing stock rewards technicians who look past surface dust to find the structural duct problems underneath - which is why we also offer Duct Sealing - San Antonio homeowners can rely on.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. Phones are answered by a live person 24 hours a day, 7 days a week – no voicemail loops, no callback queues, no waiting until Monday for a scheduling question.
The 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. That’s not a satisfaction guarantee; it’s a specific, written obligation we put on every invoice.
We know the local conditions. Crews working Air Duct Cleaning in San Antonio regularly handle the crushed flex runs in 1970s ranch homes off Nacogdoches Road, the rodent-nested attics in Alamo Heights, and the caliche dust accumulation that settles in sagging ductwork across the metro.
Ductwork Cleaning in San Antonio
Ductwork Cleaning in San Antonio means more than blowing out visible registers. The city’s 1950s – 1980s ranch homes and 1990s – 2000s tract homes often contain original flexible ductwork prone to sagging, kinking, and debris accumulation. Our process starts with negative-air containment using Nikro equipment, then source removal with rotary brush agitation and HEPA-filtered vacuum extraction. A typical residential Ductwork Cleaning in San Antonio runs $350 – $550 for a single-system home, with larger homes or commercial properties ranging $450 – $650.
When Sagging Runs Need Re-Securing
We opened an original 1960s single-story ranch in Monte Vista and found the supply run in the back bedroom sagging against the attic joist, packed at the low point with caliche dust and live oak pollen, and a disconnected collar at the air handler that was dumping conditioned air into the attic. After negative pressure containment, source removal with agitation tools, and HEPA filtration on the vacuum, we re-secured and sealed the sagging run and reconnected the collar - the homeowner noticed the back bedroom finally held temperature. This kind of repair is separate from our Dryer Vent Cleaning in San Antonio, though both address hidden airflow losses. The re-securing and sealing added $180 – $280 to the base cleaning, priced in writing before we started the repair.
Commercial Systems and Multi-Zone Homes
Larger San Antonio homes with zoned systems, or commercial properties near Loop 410 and I-10, require extended setup time and larger-capacity negative-air machines. These jobs start at $550 and scale based on access difficulty and system complexity. We specify the equipment roster – Rotobrush rotary systems, Nikro negative-air units – and the hour estimate before work begins.
Air Duct Inspection in San Antonio
Air Duct Inspection in San Antonio uses video borescope cameras to document conditions inside duct runs that homeowners never see. For pre-1990s homes in Alamo Heights, Monte Vista, and similar neighborhoods, we consider camera inspection essential before quoting cleaning or repair work. The inspection reveals rodent intrusion, separated joints, collapsed flex sections, and debris depth that register readings can’t detect. A standalone Air Duct Inspection in San Antonio costs $150 – $250; we credit this toward the cleaning or repair if you proceed with the work.
What Camera Inspection Reveals
Our technicians feed a lighted borescope through supply and return registers, recording video of internal conditions. In San Antonio’s older homes, we regularly find rodent nesting behind insulation, disconnected collars at plenum connections, and low points in flex runs where caliche dust has accumulated to several inches deep. You see the footage. We explain what it means for airflow, energy loss, and indoor particulate load. No interpretation without documentation.
Inspection as Pre-Work Documentation
The inspection video becomes the basis for our written quote. If we find a crushed or disconnected run, we show you the exact location and explain the repair before pricing it. This prevents the all-too-common scenario where a “cleaning” quote balloons after the technician is already inside your home.
Trusted Brands We Service in San Antonio
Our equipment roster includes Nikro negative-air machines, Rotobrush rotary brush systems, and filtration products from Honeywell and Aprilaire. For customers who need Trane service in San Antonio, we apply the same rigorous standards to system-specific maintenance and repair. We stock common replacement components – collars, straps, mastic, and register boots – in our San Antonio warehouse, which means repairs that would otherwise require a return visit often finish same-day. For specialized filtration upgrades after cleaning, we size and install Honeywell and Aprilaire media filters matched to your system’s airflow capacity, not oversold on MERV rating.
Common Air Duct Cleaning Problems We See in San Antonio Homes
- Sagging flex runs packed with caliche dust. In San Antonio’s pre-1990s ranch homes, the original flex duct runs often sag enough that the low point fills with caliche dust and live oak pollen, so what homeowners call “duct cleaning” is frequently a duct re-securing and sealing job once you open the system. The combination of heavy caliche dust, year-round HVAC operation, and 1950s – 1980s flex duct means debris doesn’t just coat the walls – it physically pulls runs down at the sag.
- Disconnected or crushed runs misdiagnosed as dirty ducts. Calling it a “clean” when the real problem is a disconnected, crushed, or rodent-chewed flex run in an attic – the debris is a symptom, not the issue. We find this regularly in homes off Nacogdoches Road and in older neighborhoods where attic access is limited and previous owners deferred maintenance.
- Redistributed pollen from inadequate equipment. Running a shop vac or low-powered blower without negative pressure just redistributes caliche dust and live oak pollen back through the supply and return ducts instead of removing it. San Antonio’s heavy pollen loads require containment-level extraction, not surface disturbance.
- Rodent damage hidden behind insulation. Skipping camera inspection on pre-1990s Alamo Heights and Monte Vista homes where original ductwork hides rodent nesting and separated joints behind insulation misses the actual problem. Warm climate and mature tree canopy make these neighborhoods particularly susceptible to attic rodent activity.

FAQs About Air Duct Cleaning in San Antonio
San Antonio’s heavy caliche dust and live oak pollen coat duct systems more aggressively than in other Texas markets, and the city’s pre-1990s neighborhoods often have flex duct runs that sag and collect this debris. Year-round HVAC operation – hot, humid summers averaging 90s°F and mild winters – circulates particulate constantly, accelerating accumulation. Most San Antonio homeowners with original ductwork benefit from inspection every 2 – 3 years and cleaning when video inspection shows significant debris or airflow restriction. Call (361) 326-5060 to schedule a camera inspection.
We regularly find rodent nesting behind insulation, separated joints at plenum connections, and sagging flex runs packed with caliche dust and pollen at the low point. In Monte Vista specifically, we’ve documented disconnected collars dumping conditioned air into attics and runs crushed by decades of foot traffic in tight crawl spaces. Camera inspection reveals these conditions before any work is priced, so you know exactly what needs repair versus routine cleaning.
We stop the cleaning, show you the camera footage, and explain the repair in plain terms before writing a price. Re-securing a sagging run with proper support straps and sealing with mastic typically takes 1 – 2 hours and adds $180 – $280. Replacing a crushed or rodent-chewed flex section runs $220 – $340 including materials. You approve the repair price in writing before we continue. The 365-Day Done Right Promise covers both the cleaning and any repair we perform.
Yes, our source removal methodology follows NADCA ACR guidelines for containment, agitation, and HEPA filtration. In San Antonio specifically, this matters because the city’s heavy particulate loads and older flex duct systems require negative-pressure containment to prevent redistribution of caliche dust and pollen during cleaning. NADCA-standard HEPA filtration on our Nikro equipment captures particles down to 0.3 microns, which is critical for homes with live oak pollen sensitivity or respiratory concerns.
Most San Antonio residential systems handle MERV 8 – 11 without airflow restriction; we size the filter to your system’s rated capacity after measuring static pressure. Higher MERV ratings trap more pollen and caliche dust but can strain older blower motors. After cleaning, we recommend starting with MERV 8 and upgrading only if your system demonstrates adequate airflow. We stock Honeywell and Aprilaire filters and can install a properly sized media cabinet if your current setup uses thin throwaway filters. Call (361) 326-5060 and we’ll check your system’s specifications.
