Why San Antonio Homeowners Choose Bellows Air Duct & Vent Co.
We’ve been in San Antonio long enough to know the difference between a house near the Trolley Stop in Alamo Heights and a postwar ranch in Five Points. The ductwork challenges aren’t the same, and we don’t treat them like they are. Our technicians are background-checked, uniformed, and carry camera inspection equipment on every truck. You’ll see the inside of your ducts before we touch a tool, and you’ll see them again when we’re done.
Homeowners in Dignowity Hill and Fulton call us because we’ve earned a strong local reputation over thirteen years here. We’re licensed and insured, and our pricing is disclosed upfront before work begins. No bait coupons, no price changes at the door. If something’s not right, our 90-Day Done Right Promise means we return at no charge with no paperwork required. That’s not a slogan - it’s stamped on every job we do.
Calls are answered by a live person 24 hours a day. Not an app, not a voicemail tree. If you need us, we’re here.
Air Duct Cleaning Services We Offer in San Antonio
Air Duct Cleaning
We clean the full supply and return duct network using professional-grade Rotobrush and Nikro equipment, with camera verification before and after. Every residential system we touch in San Antonio gets the same thorough treatment, whether it’s a historic home near King William or a newer build in Live Oak. Learn more about our Air Duct Cleaning in San Antonio.
Dryer Vent Cleaning
Lint accumulation in dryer vents is a genuine fire hazard, and San Antonio’s hard water minerals can compound airflow restrictions in older vent runs. We clear the full vent path from appliance to exterior termination and verify flow rates before we leave. Learn more about our Dryer Vent Cleaning in San Antonio.
HVAC Cleaning
Coils, blower assemblies, and plenums collect biological growth in San Antonio’s humidity, especially when attic temperatures spike past 140°F in summer months. We clean these components with Abatement Technologies equipment to restore system efficiency and indoor air quality. Learn more about our HVAC Cleaning in San Antonio.
Duct Repair & Sealing
Retrofitted ductwork in San Antonio’s older homes - particularly the Victorian and vernacular masonry stock in ZIP codes 78202-78210 - suffers from flex-duct liner breakdown and seam separation after years of attic heat exposure. We repair and seal with materials rated for Texas Hill Country temperature swings.
Air Quality & Sanitizing
For homes with allergy sufferers or recent water intrusion, we apply EPA-registered sanitizing treatments using Honeywell-specified protocols. This is not a substitute for physical cleaning, but a targeted step for homes where mold or bacterial contamination has been confirmed through camera inspection.
Neighborhoods We Serve in San Antonio
We work across San Antonio’s full metro area, with same-day and next-day availability throughout the city. These are the neighborhoods we know best:
- Dignowity Hill - Historic homes with retrofitted ductwork requiring careful handling
- Five Points - Mix of midcentury and newer construction with varied system ages
- Fulton - Established residential with older HVAC infrastructure
- Government Hill - High rental turnover near Fort Sam Houston, often neglected systems
- Alamo Heights - Including properties near the Trolley Stop corridor
Most San Antonio appointments are scheduled within 24 hours of your call.
Why San Antonio’s Climate & Housing Affect Air Duct Cleaning
San Antonio sits squarely in the Ashe juniper 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. From December through February, that pollen cakes the interior of ductwork. Then April hits, and your AC runs nearly nonstop through October - pulling humid Gulf Coast air through the same system. The result is a dual contamination cycle: winter cedar pollen layered with summer biological growth that cities like Dallas or Houston, lacking the Hill Country cedar exposure, simply don’t face.
The housing stock compounds this. In ZIP codes 78211, 78212, 78213, and 78214 - covering neighborhoods like Government Hill and the streets near Fort Sam Houston - central forced-air was retrofitted into homes built between the late 1800s and early 1900s. Ductwork runs through attics that exceed 140°F in July and August, accelerating flex-duct liner breakdown far faster than in newer builds. We’ve pulled collapsed duct sections in Dignowity Hill that were literally baking against roof decking.
San Antonio’s limestone geology adds another factor. Caliche dust from the region’s constant residential development infiltrates poorly sealed return plenums. Combine that with spring and fall humidity that promotes condensation inside duct runs, and you’ve got conditions for mold colonization on top of everything else. This isn’t generic “Texas heat” - it’s a specific set of forces that demands specific attention.

FAQs About Air Duct Cleaning in San Antonio
Most San Antonio homes fall between $300 and $600 for a complete residential cleaning, depending on system size and condition. We disclose your exact price before starting, and we never change it at the door. Call (844) 685-6342 for a free estimate.
Given San Antonio’s cedar pollen season and year-round AC use, we recommend every 3-5 years for most homes, and every 2-3 years if you have allergies, pets, or live in a high-turnover rental near Fort Sam Houston where prior maintenance is unknown. Homes in older neighborhoods like Dignowity Hill or Five Points may need more frequent inspection due to retrofitted ductwork aging in extreme attic heat.
We often can. We schedule same-day and next-day appointments across San Antonio, and our technicians carry full equipment on every truck. If you’re dealing with musty smells, visible mold, or post-construction dust from caliche-heavy development, we’ll get there when you need us. Call (844) 685-6342 to check today’s availability.
Repair and sealing is almost always the more economical choice for localized damage - typically $150-$400 versus thousands for full replacement. We camera-inspect first to show you exactly what we’re seeing. If replacement is genuinely necessary, we’ll tell you straight. Either way, you’ll know before we start.
We keep four offers active: $50 off any repair over $250, a free second opinion on any written estimate, an $89 seasonal tune-up, and a permanent 5% senior and veteran discount. We don’t run bait coupons or surprise “today only” pressure - just honest pricing, shown upfront.
