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.

Our Air Duct Cleaning Services in San Antonio
Residential Duct Cleaning
San Antonio’s housing stock - 1970s-1990s slab-on-grade tract homes along Loop 410 and 1604, plus 20-30-year-old flex-duct builds in Stone Oak and Alamo Ranch - creates predictable failure patterns. Our residential service covers full source removal with negative-pressure extraction (suction that pulls debris out while HEPA filtration keeps it from re-entering your home) and agitation tools that break loose the caliche dust and pollen layers adhered to duct walls. We clean supply and return sides both; cleaning only one just moves the problem around.
Commercial Duct Cleaning
Commercial buildings in San Antonio’s medical corridor near the South Texas Medical Center and retail spaces along I-10 face the same cedar pollen and humidity load as homes, but with higher occupancy and more complex zoned systems. We use Abatement Technologies commercial-grade negative-pressure units and document every trunk line and branch. Written scope and price before work starts, photo record after, same as our residential standard.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In San Antonio, these lines run through attics hitting 140-160°F nine months a year, and the flex-duct inner liners degrade. We see detached boots on the northwest side pulling raw attic air straight into supply runs - the homeowner feels “weak airflow” and assumes the AC is failing. Our Air Duct Cleaning team inspects with a camera first, then cleans with source removal if the duct is intact, or flags detached connections for repair before cleaning.
Return Duct Cleaning
Return ducts pull air back to the HVAC unit, and in San Antonio they’re the primary entry point for Ashe juniper pollen during Cedar Fever season. The return plenum and trunk lines accumulate a fine, respirable allergen load that standard filters don’t catch. We clean the full return path, including the plenum (the large central chamber where return air collects before entering the furnace or air handler), because that’s where the heaviest concentration settles.
Full System Cleaning
Our most comprehensive service. Every supply run, every return run, the plenum, and the registers (the visible vents in your walls or ceilings) - all photographed, all cleaned, all documented. In San Antonio’s climate, this is what actually addresses the pollen-and-moisture cycle. Partial cleaning leaves the microbial load in place.
Video Inspection
We run a camera through your duct system before quoting. You see what we see: detached boots, liner seam separation, debris depth, mold at condensation points. The video becomes part of your job record. No guesswork, no upsell based on fear.

BeforeAfterTrusted Brands We Service in San Antonio
CleanRun crews carry professional-grade equipment from Rotobrush, Nikro, Honeywell, and Aprilaire - brands you can look up independently before agreeing to any price. Rotobrush brush-and-vac systems agitate debris from duct walls while simultaneous suction removes it. Nikro and Abatement Technologies negative-pressure machines maintain containment during cleaning. We don’t use shop vacs with duct tape attachments, and we don’t sell fogging “sanitiser” upsells that mist a few registers and leave the actual debris untouched.
Common Air Duct Cleaning Problems We See in San Antonio Homes
- Cedar pollen loading in return systems. Every December through February, Ashe juniper releases record pollen loads that overwhelm HVAC filters and deposit throughout return ducts. The furnace running during these months recirculates the particles all winter. A real cleaning removes the accumulated layer; a fogging upsell doesn’t touch it.
- Detached flex-duct boots in attic systems. The extreme heat cycling in San Antonio attics makes flex-duct collar connections brittle. We find boots completely separated from trunk lines in Stone Oak, Alamo Ranch, and Helotes homes, pulling 140-160°F attic air and fiberglass particles into supply runs. Homeowners feel weak cooling and blame the AC unit.
- Condensation-driven mold at flex-duct liner seams. Gulf moisture surges push attic humidity to 80-90%, and cold duct surfaces in that hot attic create condensation. Mold colonizes the liner seams and boot connections. Source removal with negative pressure and HEPA filtration addresses it; surface fogging doesn’t reach inside the liner.
- Caliche dust and pest debris in older metal ducts. Original galvanized sheet-metal systems in 1970s-1980s homes near Fort Sam Houston and the South Side contain decades of fine limestone construction dust layered with cockroach frass - a load uniquely heavy in San Antonio’s humid subtropical microclimate. Agitation tools and negative-pressure extraction remove it; blow-and-go cleaning just stirs it airborne.
Pricing for Air Duct Cleaning in San Antonio, TX
Here’s what air duct cleaning costs in San Antonio, based on system type and what we actually find:
| Service | Typical Range |
|---|---|
| Residential full system cleaning (single HVAC unit, up to 15 duct runs) | $380-$680 |
| Video inspection only (applied to job if work proceeds) | $125-$175 |
| Additional HVAC unit (second system, common in larger Stone Oak/Alamo Ranch homes) | $280-$450 |

| Duct repair/sealing (detached boots, mastic sealing, collar replacement) | $180-$420 |
What moves the price: number of duct runs, whether we find detached boots or separated liners that need repair before cleaning, and accessibility (some San Antonio attics are tight crawl spaces above low-slope roofs). We deliver the written price before any work starts - Haven Standard Clause 1 - and that price is per system, not per vent. No $99 teaser that becomes $800 on arrival.

FAQs - Air Duct Cleaning in San Antonio
The attic is hot, but the duct surface is cold when AC runs nine months a year. Gulf moisture surges push relative humidity to 80-90%, and that warm, humid attic air hits cold duct metal or flex liner, creating condensation. Mold colonizes the liner seams and boot connections where water collects. Source removal with negative-pressure extraction and HEPA filtration addresses the mold and the moisture-degraded debris; surface fogging doesn’t dry the condensation or reach inside the liner. Call (830) 549-6847 for a camera inspection and written quote.
Ashe juniper pollen is drawn into return ducts while your furnace runs December through February, then recirculated all winter. The particles are small enough to pass standard filters and deposit throughout the return plenum and supply runs. By March, San Antonio ducts carry a fine allergen layer on top of nine months of attic-baked particulate. A real cleaning removes this accumulation with agitation and negative pressure; a fogging upsell leaves it in place. Call (830) 549-6847 for a free estimate - we’ll show you the debris depth on camera.
Most Stone Oak flex-duct systems can be cleaned if the liner is intact and boots are properly connected. We camera-inspect first. If boots are detached - common after 20+ years of attic heat cycling - we reattach and mastic-seal them as part of our Duct Repair & Sealing in San Antonio, then run source removal. Replacement is only needed if the liner is torn or the flex is collapsed. We give you the camera footage and a written price for either scenario before any work starts. Call (830) 549-6847.
No. A $99 special typically means a shop vac at a few registers, no negative pressure, no camera, no photo record. A “sanitising fog” mists chemical into the plenum or visible vents but doesn’t remove the settled cedar pollen, caliche dust, or mold colonies inside the duct runs. You can’t sanitise what you haven’t removed. Real source removal takes 3-5 hours for a typical San Antonio home and requires professional equipment. Call (830) 549-6847 for a written price on actual cleaning.
Every 3-5 years for most San Antonio homes, sooner if you have pets, recent remodeling, or occupants with allergies or asthma. The combination of nine-month cooling seasons, Cedar Fever pollen loading, and Gulf moisture condensation accelerates particulate and microbial buildup compared to northern climates. Homes with 20-30-year-old flex duct in attic systems should be camera-inspected every 2-3 years to catch boot detachment before it pulls attic air for a full season. Call (830) 549-6847 to schedule inspection and get a written price.
