San Antonio’s not like other Texas markets. The Hill Country heat, the cedar pollen that won’t quit, and the caliche dust that gets into everything mean duct cleaning here requires equipment and experience that national franchise crews often don’t bring. We’ve learned that the hard way, job by job, from Government Hill to the far edges of Bexar County.

Why Bellows Air Duct & Vent Co. of Texas Is San Antonio’s Preferred Air Duct Cleaning Company

We’ve built our reputation in San Antonio on showing up when we say we will and leaving the ducts cleaner than we found them - verified by camera, not claimed. Our Air Duct Cleaning team knows the difference between a 2019 build in Stone Oak with pristine flex duct and a 1950s West Side retrofit where the original window-unit openings still leak conditioned air into the walls.

San Antonio customers call us back because our 90-Day Done Right Promise means something. If the work isn’t right, we return at no charge. No paperwork to file, no argument. Wade Kellerman put that in writing when he founded Bellows in 1984, and it’s still how we operate.

Response time to San Antonio varies by location, but we schedule to minimize your wait and keep you informed. Calls are answered by a live person 24 hours a day - not a voicemail tree, not an app. Most San Antonio jobs are completed in one visit by background-checked, uniformed technicians who arrive with the right equipment for your specific ductwork.

We understand local conditions that out-of-town crews miss. The 150°F attic temperatures in summer that degrade duct liner. The Gulf moisture surges that turn poorly sealed returns into mold incubators. The cedar pollen that keeps circulating through January and February long after outdoor counts drop. This is San Antonio-specific knowledge, earned through decades of service.

Our Air Duct Cleaning Services in San Antonio

Residential Duct Cleaning

San Antonio’s housing stock demands a tailored approach. In neighborhoods like Dignowity Hill and Government Hill, we regularly find 1920s-1960s masonry homes where central AC was shoehorned in decades after construction, with flex duct routed through unconditioned attics. That ductwork accumulates debris faster than in newer homes, and the seals fail earlier. We clean the full supply and return network, inspect every connection, and show you before-and-after camera footage so you see what came out. Our $89 Seasonal Tune-Up can catch problems before they require full cleaning.

Commercial Duct Cleaning

San Antonio’s commercial buildings - from the medical corridor near the South Texas Medical Center to retail along Loop 410 - need scheduled duct maintenance that doesn’t disrupt operations. We work after hours and weekends, use containment to protect your space, and provide documentation for facility managers and compliance officers. Our Rotobrush and Nikro equipment handles the higher static pressures and larger duct dimensions common in commercial installs.

Supply Duct Cleaning

Supply ducts carry conditioned air to your rooms. In San Antonio, where AC runs 8-9 months a year, these lines move enormous air volumes and collect dust at accelerated rates. We see supply registers completely choked with debris in homes near ongoing construction on the Edwards Plateau, where caliche limestone dust infiltrates through every gap. Our supply duct cleaning restores airflow and reduces the load on your compressor, which matters when San Antonio summer electricity bills spike.

Return Duct Cleaning

Return ducts pull air back to the handler, and they’re often the dirtiest part of the system - especially in San Antonio’s older homes with original return chases built into wall cavities. These unlined channels collect decades of dust, pollen, and in humid months, mold. We clean and inspect returns with camera verification, and we note where humidity intrusion or poor sealing creates conditions that will require attention again.

Full System Cleaning

For San Antonio acreage properties and larger homes, we recommend full system cleaning that covers every component: supply ducts, return ducts, trunk lines, plenums, and the air handler cabinet. This is particularly important for homes with multiple structures - a main house plus workshop, guest house, or barn with tied-in HVAC. We serviced a 3,500 sq ft acreage home in the Helotes area near 78208, where the homeowner’s workshop had a 14-foot garage door with a heavy-duty LiftMaster opener failing due to a snapped spring. We arrived ready with a full inventory of commercial-grade springs and openers, completed the repair and duct inspection in one trip, and verified the flex duct wasn’t caked with the fine caliche dust common in West Side homes. One trip. Done right.

Video Inspection

Every Bellows job includes camera inspection before and after cleaning. In San Antonio, this matters more than you might think. We’ve found collapsed flex duct in Terrell Hills attics, rodent damage in Alamo Heights crawlspaces, and disconnected returns in Kirby homes where the original installer never sealed the joint. The camera doesn’t lie, and the footage belongs to you.

Trusted Brands We Service in San Antonio

We run professional-grade equipment from Rotobrush, Nikro, and Honeywell - the same brands serious HVAC contractors specify for commercial and residential work. For San Antonio customers, this means we can source replacement parts and filtration upgrades without the delays that come from ordering unfamiliar equipment. Our technicians train on these systems specifically, so when we encounter a Honeywell electronic air cleaner in a Windcrest home or a Rotobrush duct cleaning machine specification for a commercial job downtown, we know exactly what we’re looking at. Fast turnaround starts with knowing your equipment.

Common Air Duct Cleaning Problems We See in San Antonio Homes

• Cedar pollen contamination from December through February. San Antonio sits at the epicenter of “Cedar Fever” country. Ashe juniper releases pollen in extreme volumes that penetrates poorly sealed ductwork and recirculates through HVAC systems long after outdoor counts fall. This seasonal contamination pattern unique to the Hill Country cedar belt drives genuine post-season duct cleaning demand here that simply doesn’t exist in neighboring cities at the same intensity.
• Caliche limestone dust accumulation in aging flex duct. In West Side and Near East Side homes, 1940s-1950s houses with 1980s central AC retrofits frequently have undersized, improperly sealed flex duct caked with fine caliche dust - a chalky white particulate stirred by San Antonio’s persistent construction activity on the Edwards Plateau limestone substrate. Standard national duct-cleaning protocols aren’t designed for this. We are.
• Mold growth from Gulf moisture in unconditioned attics. Summer humidity surges push moist air into poorly sealed duct systems, especially in the 78201-78210 ZIP codes where original ductwork was never meant to handle modern cooling loads. We find active mold in returns and trunk lines that homeowners never suspected.
• Undersized equipment on acreage properties with multiple structures. San Antonio’s rural spreads in Bexar County’s outskirts often feature detached workshops with oversized doors and heavy-duty openers requiring specialized service. Underestimating the extra travel and labor time, or using standard cleaning equipment that can’t handle heavy caliche dust, leads to rushed, incomplete work and callbacks. We bring commercial-grade equipment and plan for the full scope.
