Fast, Reliable Air Duct Cleaning Across San Antonio
Air duct cleaning in San Antonio typically runs $350-$650 for a standard residential system and most jobs finish in a single visit. We’re Bellows Air Duct & Vent Co., and we’ve been sending crews to San Antonio since long before the Hill Country became the bedroom community it is today. If you’re calling from a place off Bandera Road with a detached shop, a main house, and maybe a guest casita, you already know: not every company wants to make that drive, and not every crew shows up with the right equipment for the job.
We do. Our technicians cover all of San Antonio, from the historic masonry homes near Dignowity Hill out to the acreage properties past Loop 1604. Calls come through to a live person, 24 hours a day, at (844) 685-6342. We’ll give you an honest price before we start, and we’ll be there when we say.
Why Bellows Air Duct & Vent Co. Is San Antonio’s Preferred Air Duct Cleaning Company
San Antonio homeowners know the difference between a company that mails it in and one that stands behind the work. We’ve built our reputation in this market on showing up prepared, doing the full job, and leaving a written guarantee behind.
Our Air Duct Cleaning team carries professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, the same brands serious HVAC contractors specify. Every job gets a camera inspection before and after, so you see what was in there and what came out. No claim without proof.
Response time to San Antonio averages same-day or next-day for standard calls, and we do not subcontract. The technician who arrives at your door is background-checked, uniformed, and answers to our office, not to an app.
Ray Castillo, who leads Bellows Air Duct & Vent Co., set the standard back in 1984: one honest price shown before work starts, no bait coupons, no price changes at the door. That standard hasn’t moved in 42 years.
Our Air Duct Cleaning Services in San Antonio
Residential Duct Cleaning
San Antonio’s housing stock runs old and runs hot. The inner-city ZIP codes covering neighborhoods like Dignowity Hill, King William, and Government Hill are packed with late-1800s to early-1900s Victorian and vernacular masonry homes where central forced-air systems were retrofitted decades after original construction. Ductwork in these houses routes through attic spaces that regularly exceed 140°F in summer, accelerating flex-duct liner breakdown and insulation degradation far faster than in newer builds. Our residential cleaning addresses the full supply and return network, not just the vents you can see.

Commercial Duct Cleaning
Commercial systems in San Antonio face a dual load: Gulf Coast humidity pushing biological growth through spring and fall, and near-constant construction generating caliche dust that infiltrates intake systems. We clean restaurants near the Trolley Stop in Alamo Heights, medical offices serving Fort Sam Houston, and retail spaces throughout 78211, 78212, 78213, and 78214. Our commercial crews work after hours when needed, and every job is camera-documented for your maintenance records.

Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces. In San Antonio, they’re also the delivery path for cedar pollen during mountain cedar season, December through February. We use negative-air HEPA extraction to remove settled debris from supply trunks and branches, then verify flow rates at each register. If your system was designed for a smaller home and later expanded, we flag the pressure imbalances that waste energy and spread dust.

Return Duct Cleaning
Return ducts pull air back to the handler, and in San Antonio’s older homes they’re often the most neglected component. Retrofitted returns in masonry homes frequently run through unconditioned crawl spaces or exterior chases, pulling in attic heat, humidity, and construction dust. We clean the full return path, including the filter rack and blower compartment, and we seal the leaks that let unfiltered air bypass your filter entirely.

Full System Cleaning
A full system cleaning covers supply ducts, return ducts, the blower assembly, evaporator coil, and filter housing. In San Antonio, this is the service we recommend for homes that haven’t been cleaned in five or more years, or for properties with known contamination: mold from condensation, pet dander from previous occupants, or the accumulated cedar pollen and caliche dust that define this market. Most full system cleanings complete in one visit.

Video Inspection
Every Bellows job starts and ends with a camera. For San Antonio’s older homes, especially the retrofitted systems in Government Hill and Five Points, video inspection often reveals collapsed flex liners, disconnected boots, or rodent damage hidden behind equipment. We show you the footage. No surprises, no guesses.

Trusted Brands We Service in San Antonio
We run professional-grade equipment from Nikro, Honeywell, and Abatement Technologies, brands that HVAC contractors in San Antonio specify for their own jobs. Our vans carry Rotobrush contact cleaning systems for residential trunk lines, Nikro HEPA negative-air machines for commercial jobs, and Abatement Technologies sealing products for duct repair. We stock common fittings and access panels locally, so most repairs don’t wait on parts. If your system uses Aprilaire media filters or Honeywell electronic air cleaners, we service those too, and we’ll tell you straight if the component is worth keeping or replacing.
Common Air Duct Cleaning Problems We See in San Antonio Homes
- Cedar pollen saturation during winter months. San Antonio sits in the Ashe juniper belt, and December through February deposits some of the densest pollen concentrations in the country into HVAC intake air. Ducts that were clean in November can be coated by March.
- Mold from Gulf Coast humidity and limestone geology. San Antonio’s position at the edge of the moisture corridor means indoor humidity stays elevated even in shoulder seasons. Condensation inside poorly-insulated duct runs promotes mold colonization, compounded by fine caliche dust from constant regional development.
- Flex-duct degradation in superheated attics. In neighborhoods like Dignowity Hill and Fulton, retrofitted ductwork runs through attics that exceed 140°F for months each summer. The liner adhesive fails, insulation compresses, and the duct starts pulling attic air directly into your system.
- Deferred maintenance in high-turnover rental properties. Near Fort Sam Houston, military PCS turnover means rental properties cycle every 1-3 years with little attention to ducts between leases. We regularly find systems packed with years of accumulated debris from multiple previous tenants.
Pricing for Air Duct Cleaning in San Antonio, TX
A typical residential duct cleaning in San Antonio runs $350-$650 for a standard single-system home. Full system cleaning, including blower and coil, generally falls between $550-$950. Commercial jobs start around $800 and scale with system size and access difficulty.
What moves the number: the number of supply and return vents, whether the system has been cleaned before (first cleans take longer), accessibility of the air handler, and any repair or sealing work needed. Homes with detached workshops or multiple structures, common on San Antonio acreage properties, are priced as separate systems.

San Antonio’s Unique Air Duct Challenges: Cedar, Caliche, and Heat
San Antonio sits squarely in the Ashe juniper (mountain cedar) belt of the Texas Hill Country, and its infamous “cedar fever” season deposits some of the densest pollen concentrations in the country directly into homes through HVAC intake air. Because AC systems also run nearly continuously from April through October in San Antonio’s extreme heat, ducts accumulate both summer biological growth and winter cedar pollen, creating a year-round dual contamination cycle that cities like Dallas or Houston simply do not face.
We serviced a 1950s ranch home in Government Hill, where decades of military PCS turnover left the duct system untouched. Our crew extracted 6 gallons of caliche dust and cedar pollen using a Rotobrush system, then sealed multiple flex-duct leaks with Abatement Technologies mastic. The homeowner had lived there twelve years and never known the system was that far gone.
San Antonio’s limestone geology generates fine caliche construction dust that infiltrates duct systems during the region’s near-constant residential and commercial development. If you’re near active construction, or if your home dates to a period when the surrounding area was still being graded, that dust is in your system. We see it on camera every week.

FAQs - Air Duct Cleaning in San Antonio
Most San Antonio homes need duct cleaning every 3-5 years, but homes sensitive to mountain cedar pollen should consider cleaning in late February or early March, after peak season. The pollen that enters through your intake doesn’t all get caught by the filter; much of it deposits in the return trunk and blower compartment, then recirculates for months. Call (844) 685-6342 to schedule a post-season clean, or ask about our $89 Seasonal Tune-Up to assess your filter and blower condition.
San Antonio’s rural acreage properties often feature detached workshops and heavy-duty garage doors requiring specialized spring and opener service, a demand absent in denser urban cores. Standard-duty springs and openers fail prematurely on oversized doors, and the longer service drives mean you need a crew that arrives with the right parts in the truck, not a diagnosis and a return trip. We size springs by door weight and cycle life, not by guesswork.
Yes, especially for homes built before 1950 with retrofitted HVAC. The flex-duct liners in these systems often collapse or detach behind equipment where you can’t see from the register. Our camera inspection finds the disconnects, rodent damage, and collapsed sections that a simple vent cleaning would miss. We show you the footage before we quote any repair.
Duct cleaning removes the caliche dust that has already entered and settled in your system, and sealing the ductwork prevents new infiltration. Caliche dust from limestone geology and regional construction is finer than typical household dust; it passes through standard filters and accumulates in blower motors and evaporator coils, reducing efficiency and spreading particles. A full system clean with HEPA extraction addresses the buildup, and our camera inspection identifies the leaks that let it in.
High military PCS turnover means rental properties near Fort Sam Houston often go 1-3 years between any maintenance, with each new tenant adding pet dander, personal care product residue, and debris to a system that hasn’t been cleaned. We regularly find ducts in these homes that haven’t been touched since the previous military family moved in, packed with years of accumulated contamination. If you’re moving into a rental near the base, a camera inspection and cleaning should be part of your move-in checklist. Call (844) 685-6342 for a free estimate.
