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 in San Antonio costs between $390 and $720 for a typical single-family home, depending on the number of systems and how much contamination has built up inside the runs. For rural properties on the northwest fringe around Helotes and along unincorporated Bexar County roads, whole-system work with multiple returns and a detached outbuilding usually lands between $550 and $900. At Linden Air Duct Cleaning, every San Antonio job starts with a written price before any work begins, so you know exactly what the visit costs before our tech unrolls a hose. Call (980) 447-2498 and a live person answers, any hour, any day.
Most San Antonio homeowners call us after noticing weak airflow, a dust film returning to furniture within days of cleaning, or because cedar season hit the household hard between December and February. This page gives you the honest, local picture of what duct cleaning involves in Bexar County, what it costs here, and why rural systems around San Antonio need a different approach than a suburban slab home on the north side.
Why Linden Air Duct Cleaning Is San Antonio’s Preferred Air Duct Cleaning Company
We answer the phone with a real person. Not a queue, not a callback request. That matters when you’re sorting out whether the dust on your return grille is normal or a sign that a 1980s flex run has pulled loose above your ceiling. That matters more if you’re home alone with young children and want to know exactly who is walking up the driveway.
Our Air Duct Cleaning team works the full San Antonio metro every week, from the Randolph AFB corridor through Universal City and Converse out to Alamo Ranch. We know these homes. The ranch-style slab builds of the 1970s through 1990s, the attic-flex systems that bake at 140°F in July, the new-construction subdivisions where post-drywall dust coats supply runs before the first owner moves in. That local familiarity changes how we clean, because we know what we’re going to find before we open the first register.
Every technician who arrives at a San Antonio home is background-checked, identity-verified, and photo-badged under the Threshold Standard. We send the tech’s name and photo to you before the visit, and they present ID at the door. No exceptions. Every job carries our 365-Day Done Right Promise in writing, and every repair gets a written guarantee with a free second visit if the repair fails. We’ve operated to this standard since 2004 as part of the Threshold Group family.
Residential Air Duct Cleaning in San Antonio
Residential Air Duct Cleaning in San Antonio means pulling years of accumulated cedar pollen, caliche dust, pet dander, and construction debris out of the supply and return runs that move conditioned air through your house. For a typical 2,000-square-foot San Antonio home with attic flex duct, expect $390 to $720 for a full system cleaning with negative-pressure extraction. We scope every system first, because half the homes we open up on the northeast and far northwest sides have ductwork that’s been partially disconnected at the boot collars for years, recirculating basement-level debris into the living space.
What the Job Actually Involves
We connect a HEPA-filtered negative-air machine to the main trunk, then work each branch run with agitation tools while the system is under vacuum. On San Antonio attic-flex systems, that means checking every boot collar connection before agitation starts, because a separated collar on the return side turns the whole cleaning into a dust redistribution exercise. After we finish the mechanical cleaning, we camera the main trunk and representative branch runs so you see what came out.
When a San Antonio Home Needs It
If you’re running your AC from April through October and you can smell dust when the blower kicks on, that’s not normal. If the furniture behind your supply registers develops a gray film within a week of wiping, that’s fine particulate moving through the runs. And if your home is on unpaved limestone road frontage or you live west of Loop 1604 where caliche dust gets airborne on windy afternoons, the interval shrinks. Rural San Antonio properties often need residential duct cleaning every 18 to 30 months, not the 3 to 5 years that works for a sealed suburban home.
Commercial Air Duct Cleaning in San Antonio
Commercial Air Duct Cleaning in San Antonio covers offices, medical suites, retail bays, restaurants, and the outbuilding systems that rural property owners run for shops and barns. Commercial rates depend on square footage, number of rooftop or split systems, and whether the ductwork is exposed spiral or insulated flex. A single-tenant office under 5,000 square feet in a San Antonio strip center generally runs $900 to $1,800. Larger buildings with multiple zones and rooftop units run higher, and we quote those after a walkthrough. Every commercial quote is in writing before work begins.
Outbuilding and Shop Systems
Detached shops, barns, and equipment buildings on San Antonio’s rural fringe collect dust at a rate suburban homes never see. Unpaved road traffic, hay or feed dust, and welding or woodworking particulate all get pulled into the duct runs. These systems need a shorter cleaning interval than the main residence and they need the same boot-collar and connection checks, because the vibration and temperature swings in outbuildings loosen fittings faster than in a conditioned home.
Post-Construction and Tenant Turnover
San Antonio’s construction tempo means we see a steady stream of new-build commercial spaces with drywall dust, insulation fibers, and sawdust still packed into supply runs. We clean those before occupancy so the first tenant isn’t paying to condition a construction site. We also do turnover cleanings for property managers around Stone Oak and the medical district, where a documented cleaning with camera images helps close out a lease without disputes over HVAC condition.
Trusted Brands We Service in San Antonio
We run Rotobrush agitation equipment with negative-pressure extraction and HEPA filtration on most residential jobs, and we work with Nikro air scrubbers on tighter commercial and outbuilding systems. For customers who want air-quality improvements beyond cleaning, we carry and install products from Honeywell, Aprilaire, and Abatement Technologies. Because we stock replacement filters, access panels, and boot-collar materials locally, we don’t have to leave a San Antonio job half-finished while parts ship from a warehouse in another state. Marcus Veale runs our San Antonio operation and makes sure every truck carries what the job will actually need.
Common Air Duct Cleaning Problems We See in San Antonio Homes
- Mountain cedar pollen packed into branch runs. Ashe juniper pollen from the December-through-February cedar season is ultra-fine and sticky when it settles. It migrates past register boots and coats the interior of branch runs, where a basic visual check misses it entirely. Camera inspection after cedar season is the only way to confirm what’s actually left in the system.
- Separated flex-duct connections at boot collars. The 1980s builder-grade systems in the Randolph AFB corridor around Converse and Schertz routinely show sheet-metal trunks with flex branches that have pulled loose at the boot collar. That separation creates a debris trap that standard brush equipment pushes right past. We reseal those connections before cleaning, not after.
- Caliche dust loading on return air intakes. The limestone caliche soils across developing areas on the south and northwest fringes throw fine mineral dust into the air on windy days. It gets drawn through return intakes and settles as an inorganic sediment layer inside the runs. On rural properties near Helotes and along unpaved roads, we regularly pull several pounds of this mineral grit out of a single system.
- Post-construction dust in new-build subdivisions. Alamo Ranch, the Helotes corridor, and the US-281 growth corridor have added tens of thousands of homes where drywall dust and insulation particulate were left inside supply runs before the first family moved in. The builder’s final clean doesn’t touch duct interiors. We clean those systems before move-in or shortly after.
Pricing for Air Duct Cleaning in San Antonio, TX
Here’s what San Antonio homeowners should expect to budget, based on what we see in this market:
- Single-family home, one HVAC system, typical 1,500 – 2,500 sq ft: $390 – $720

- Rural property with detached outbuilding or shop: $550 – $900 for the full scope, outbuilding included after inspection
- Video inspection add-on: $75 – $150 depending on system size
- Boot-collar reseal or minor duct repair work: quoted separately in writing before we start
What changes the number is the number of systems, the amount of contamination present, accessibility in the attic, and whether connections need resealing or repair before cleaning can be done properly. We don’t quote per-vent prices. We quote one flat price per system, in writing, before any work begins. If you want an exact quote for your San Antonio home, call (980) 447-2498.

FAQs About Air Duct Cleaning in San Antonio
Rural properties around San Antonio need duct cleaning every 18 to 30 months, while a sealed suburban slab home can typically go 3 to 5 years between cleanings. The difference is airborne caliche dust from unpaved roads and open land, plus the cedar pollen load that rural systems take on without the filtration benefit of dense tree cover or tighter neighborhood air movement. Call (980) 447-2498 and we’ll help you figure out the right interval for your specific property.
Mountain cedar season directly affects ductwork, and the effect is measurable. Ashe juniper pollen is ultra-fine and gets drawn deep into supply and return runs during the December-through-February bloom, coating branch interiors far beyond what household dust does. A camera inspection after cedar season on a rural San Antonio system usually shows a distinct pale pollen film that would have remained in place for years without extraction. If your household reacted hard to cedar season, the pollen load inside the ducts is part of that exposure picture.
Rural jobs start with a full boot-collar and connection check on every accessible joint, because unpaved road vibration and outbuilding temperature swings loosen fittings faster than in-town systems. We also account for the higher mineral dust load with longer agitation passes and more frequent filter changes on our negative-air equipment, and we typically run camera inspection on rural systems after cleaning because the contamination we find there is not visible from a register check. Call (980) 447-2498 for a walkthrough of what your property needs.
It’s workable, but it changes the approach. 1980s attic flex in San Antonio has usually been heat-cycled at 140°F-plus for decades, which embrittles the outer jacket and weakens the tape and collar connections. We inspect every accessible boot collar before cleaning starts and reseal separated connections so the agitation tools actually remove debris instead of pushing it past the gaps. In some cases the flex is degraded to the point where replacement is the honest recommendation, and we’ll tell you that in writing with the findings on camera.
We offer dryer vent cleaning as a standalone service and we’ll flag it during a duct cleaning visit if the vent shows heavy lint buildup, because a clogged dryer vent is a fire risk on any property. Rural homes with long exterior vent runs through crawl spaces or outbuilding walls are the ones we see packed tight with lint and sometimes bird or rodent nesting. We’ll quote the dryer vent separately in writing so you know exactly what each part of the job costs before we start.
