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.

Air duct cleaning in San Antonio typically runs $350-$650 for a whole-home residential system, with most jobs completed in a single visit. We’re Morton’s Air Duct Cleaning, and our San Antonio office coordinates scheduling and dispatch for families throughout the metro, from Stone Oak down to the South Side and across to Helotes. We’ve been part of the Cedarwell family since 2005, and every crew that rolls out here knows the local housing stock: the 1950s-1980s tract homes with flex ductwork baking in unconditioned attics, the older neighborhoods where asbestos-containing duct tape still wraps original sheet-metal trunks, and the cedar pollen load that rebuilds in ductwork every winter. Call (323) 918-4345 for a free written estimate before any work starts.

Vent Cleaning in San Antonio
Vent Cleaning in San Antonio means more than brushing off register covers. Our crews remove every supply and return grille, agitate the duct run behind it with Rotobrush tools, and extract debris under negative pressure using Nikro HEPA-filtered collection systems. San Antonio’s year-round AC use means vents accumulate a stubborn mix of cedar pollen, caliche dust, and fibrous particulate from degrading flex duct liners. A typical residential vent cleaning here runs $150-$280 for a partial system focus or $350-$650 when bundled into whole-home service.
Supply Vent Focus
Supply vents push conditioned air into your rooms, so debris here recirculates constantly. We find heavy cedar pollen buildup on supply grilles in homes near Friedrich Wilderness Park and the Northwest Side, where mountain cedar density is highest. Our technicians use compressed air whips and mechanical agitation to break loose material without damaging older flex connections.
Return Vent Deep Clean
Return vents pull air back to the handler, making them the primary collection point for household dust, pet dander, and pollen. In San Antonio’s all-electric and heat-pump homes, oversized return plenums often hide years of accumulation that standard vacuum attachments miss. We pull the return box when accessible and clean the full pathway to the blower cabinet.
Air Duct Repair in San Antonio
Air Duct Repair in San Antonio almost always starts with what we find during a cleaning. That disconnected boot at a bedroom register. Crushed flex runs where a homeowner stored holiday decorations. Joints that have separated because decades of 140°F attic heat degraded the adhesive. We don’t just clean around these problems; we stop, show you the camera footage, and quote repair before proceeding. Typical repairs run $180-$450 for individual runs or $500-$1,200 for more extensive trunk line work and resealing.
Flex Run Replacement
San Antonio’s attic temperatures destroy flex duct inner liners. Once that liner starts shedding, cleaning alone won’t stop the particulate. We replace damaged runs with properly sized, insulated flex duct and support it correctly so it doesn’t sag or crush again. No point in a clean system if the delivery pipes are falling apart.
Sheet-Metal Trunk Sealing
Older homes in Monte Vista and Mahncke Park often have galvanized steel trunks with failing tape or no sealant at all. Gulf moisture surges into these gaps, creating condensation that supports microbial growth. We seal accessible joints with mastic and mesh, not duct tape, because tape fails in attic heat within a season or two.
Trusted Brands We Service in San Antonio
Our San Antonio crews carry professional-grade equipment from Nikro, Honeywell, Aprilaire, and Abatement Technologies, not rental-shop vacuums with HEPA stickers slapped on. We stock common fittings and sealants locally so repairs don’t wait on shipping. When we encounter Honeywell or Aprilaire media filters during a cleaning, we note condition and capacity so you know whether replacement makes sense before the next cedar season hits. Our Rotobrush agitation systems and Nikro negative-air machines are maintained to manufacturer spec, because tool failure mid-job in a San Antonio attic in July isn’t acceptable. That equipment quality is part of why we can offer the 365-Day Done Right Promise on every job.
Common Air Duct Cleaning Problems We See in San Antonio Homes
- Cedar pollen saturation in supply and return trunks. San Antonio’s Ashe juniper season routinely produces the highest pollen counts recorded anywhere in North America. Because AC systems here run 8-10 months annually, that pollen doesn’t sit dormant; it recirculates through ductwork until physically removed.
- Flex duct liner degradation from extreme attic heat. Attic temperatures exceeding 140°F break down the inner liner of flex ductwork, shedding fibrous particulate directly into the airstream. Cleaning without addressing this source just means breathing liner debris again within months.
- Asbestos-containing duct tape on 1960s-70s sheet-metal systems. In neighborhoods like Monte Vista, Mahncke Park, and the near West Side, we regularly encounter original duct tape that contains asbestos. We stop work immediately, explain the finding, and discuss proper abatement before any agitation begins.
- Disconnected boots and crushed runs from attic storage activity. Because San Antonio homes lack basements, attics become default storage. We’ve found flex runs flattened by plywood sheets, holiday bins, and even disused water heaters placed directly on ductwork.
Pricing for Air Duct Cleaning in San Antonio, TX
Whole-home air duct cleaning in San Antonio typically runs $350-$650 for a standard residential system up to about 2,500 square feet. Larger homes or systems with multiple zones may reach $750-$950.

FAQs About Air Duct Cleaning in San Antonio
San Antonio’s Ashe juniper pollen season produces the highest pollen counts in North America, and because residential AC systems here run 8-10 months a year, ductwork acts as a continuous filter that re-exposes occupants to that hyper-allergenic load cycle after cycle. Post-cedar-season cleaning removes that accumulated reservoir before the next cooling season begins. Call (323) 918-4345 to schedule a post-season reset.
We typically find decades of cedar pollen, caliche dust, degraded flex liner fibers, and often disconnected or crushed duct runs in the original 1950s-1980s housing stock across the South Side, West Side, and Northwest Side. In a 1968 ranch house off Westrock Drive on the near West Side, our tech pulled a blower motor caked in cedar pollen and attic dust, then ran camera inspection through the original sheet-metal trunk line and found two crushed flex runs and a disconnected boot at a bedroom register. After setting up negative pressure with Abatement Technologies HEPA filtration, we completed source removal with Rotobrush agitation tools, reconnected the boot, and sealed the joints that were condensing Gulf moisture inside the attic chase.
Yes. Attic temperatures in San Antonio routinely exceed 140-155°F during summer, which accelerates breakdown of flex duct inner liners and causes them to shed fibrous particulate directly into the airstream. That heat also degrades adhesives and mastic on sealed joints, making re-inspection and resealing a recurring need. Cleaning without addressing heat-damaged liner material means the problem returns within a season.
Homes built or re-ducted in the 1960s-70s in Monte Vista, Mahncke Park, and the near West Side often have sheet-metal trunk lines wrapped with asbestos-containing duct tape. We stop work immediately if we encounter this, explain the finding, and discuss proper abatement before any agitation or compressed air is used. Starting agitation on asbestos tape would contaminate the home. We don’t take that risk.
We seal the system and run negative pressure with HEPA filtration during agitation, so debris is captured at the source rather than pushed into living spaces. Our crews also use drop cloths at every access point and shoe covers throughout the home. We work room by room, keeping doors closed where possible, and we photograph the clean-up before we leave so you see the condition we left behind. For families with kids or pets, we can schedule around nap times and use quieter tool settings where the job allows.
