Why Bellows Air Duct & Vent Co. of Texas Is Alamo Heights’s Preferred Air Quality & Sanitizing Company
We’ve been serving Alamo Heights homeowners since 1984, long enough to have cleaned the same duct systems twice as houses passed from one family to the next. Our Air Quality & Sanitizing team knows the local housing stock inside and out, and that matters when you’re dealing with retrofitted mid-century systems that don’t respond to textbook solutions.
Our reviews from Alamo Heights customers consistently mention two things: we show up when we say we will, and the price on the phone matches the price on the invoice. No bait coupons, no upsells at the door. That’s been our way for over 42 years.
Response time to Alamo Heights averages under an hour because our dispatch routes from central San Antonio with technicians who know the area. They don’t need GPS to find McNay Art Museum or navigate the narrow streets off Broadway. That local knowledge saves time, and time matters when your family is breathing cedar pollen through a disconnected bedroom duct.
Every technician is background-checked, uniformed, and equipped with camera inspection gear. We document what we find before we touch anything, and we show you the after. That’s not a sales tactic. It’s how we prove our 90-Day Done Right Promise in writing, with no paperwork and no arguing if something needs attention.
Our Air Quality & Sanitizing Services in Alamo Heights
Allergen Reduction
Alamo Heights sits directly in the path of the Hill Country’s Ashe juniper pollen corridor, and the 78209 zip code gets hit harder than most of San Antonio every December through January. Our allergen reduction service targets the specific pollen infiltration patterns we see in local homes: leaky retrofitted joints pulling unconditioned attic air into supply streams, decades of cedar pollen accumulation inside original galvanized runs, and disconnected flex branches that bypass your filter entirely. We use Rotobrush HEPA vacuum systems and mechanical agitation to remove accumulated strata, then seal joints to block future infiltration. Most Alamo Heights allergen reduction jobs run $275-$425 and are completed in a single visit.
Air Purifier Install
For homes with chronic pollen infiltration that sealing alone can’t stop, we install Aprilaire whole-house air purifiers rated to capture particles down to 0.3 microns, including mountain cedar pollen. These units mount directly to your existing HVAC system and treat all conditioned air, not just one room. In Alamo Heights’s older homes with undersized chases and mixed duct materials, we size and mount carefully to avoid restricting airflow through already-strained systems. Typical installation runs $850-$1,400 depending on system access and electrical requirements. Every install includes before-and-after airflow measurement.
Mold Treatment
San Antonio’s 150°F attic temperatures create perfect conditions for mold growth inside delaminating flex-duct liner, especially in Alamo Heights homes where retrofitted ductwork was stapled into unconditioned spaces without proper vapor sealing. We treat mold with EPA-registered products applied through professional-grade fogging equipment, then verify elimination with camera inspection. For extensive contamination in original metal ductwork, we may recommend partial duct replacement with sealed, insulated flex. Mold treatment in Alamo Heights typically runs $350-$650 depending on contamination extent and accessibility.
Bacteria Sanitizing
Bacteria sanitizing addresses the microbial load that builds in duct systems over decades of use, particularly in homes with poor filtration and leaky returns. Our process uses professional-grade sanitizing agents from Abatement Technologies, applied as a fine mist that coats duct interiors without pooling or dripping. In Alamo Heights’s older galvanized systems with rough interior surfaces, we adjust application technique to ensure complete coverage. This service pairs naturally with allergen reduction and typically adds $125-$195 when combined.
Odor Removal
Persistent odors in Alamo Heights homes often trace to decaying pollen strata, rodent activity in unsealed attic ducts, or bacterial growth in standing water from poorly drained condensate lines. Our odor removal process identifies the source through camera inspection and targeted testing, then treats with oxidation or enzyme-based products matched to the specific contaminant. Mixed flex-and-metal systems require particular care because odors absorb differently into each material. Standalone odor removal runs $295-$495; most cases resolve in one treatment.
UV Light Installation
UV-C lights installed at the evaporator coil or in supply plenums inhibit mold and bacterial growth on wet surfaces. In Alamo Heights’s humid climate with long cooling seasons, this prevents the musty odors and microbial spread that plague systems with poor drainage. We specify Honeywell and Aprilaire UV units sized to your system CFM. Installation typically runs $450-$750 and includes a one-year bulb replacement guarantee.

Trusted Brands We Service in Alamo Heights
We stock parts and equipment from Rotobrush, Nikro, Honeywell, and Aprilaire, the same brands serious HVAC contractors specify for demanding applications. For Alamo Heights customers, that means no waiting on special orders for filter upgrades, UV replacement bulbs, or whole-house purifier components. Our trucks carry Aprilaire media filters and Honeywell UV bulbs sized for the residential systems common in 78209. If your 1960s colonial revival needs a custom adapter to mount modern air quality equipment to vintage plenum dimensions, we fabricate it on-site rather than sending you to hunt parts.
Common Air Quality & Sanitizing Problems We See in Alamo Heights Homes
- Thermal cycling destroys retrofitted flex duct. San Antonio’s summers push attic temperatures above 150°F, which accelerates flex-duct liner degradation and causes repeated thermal expansion that loosens duct joints in Alamo Heights’s older systems. The delaminated liner releases accumulated pollen and mold spores directly into living spaces.
- Orphaned duct branches create pressurized contamination zones. Multiple HVAC equipment upgrades over decades leave behind disconnected or capped duct branches that pressurize attic spaces. Unconditioned air loaded with Ashe juniper pollen gets pulled into supply streams through unsealed joints during system operation.
- Mixed flex-and-metal systems leak at every transition point. The patchwork of materials installed during successive retrofits rarely seals properly where flex meets galvanized steel. These gaps allow mountain cedar pollen to infiltrate and settle in visible seasonal strata inside original duct runs.
- Undersized returns strain filtration and bypass particle capture. Many Alamo Heights homes were retrofitted with return air pathways too small for modern equipment airflow requirements. The resulting negative pressure pulls unfiltered attic air through every available gap, bypassing your filter entirely during peak pollen season.

FAQs - Air Quality & Sanitizing in Alamo Heights
That tan, fibrous dust is almost certainly accumulated Ashe juniper (mountain cedar) pollen that infiltrated through leaky duct joints during December and January. In Alamo Heights’s retrofitted mid-century systems, the pollen gets pulled into unsealed attic ducts during your HVAC’s negative-pressure draw, then settles in visible layers inside galvanized runs. We see this characteristic buildup so often in 78209 homes that our technicians recognize it on camera inspection immediately. Call (866) 347-2063 and we’ll show you exactly what’s inside your system, with a free estimate for removal and sealing.
UV lights help with the mold and bacterial growth that pollen accumulation promotes, but they don’t filter pollen particles themselves. For cedar pollen, we typically recommend pairing UV installation with an Aprilaire whole-house air purifier and thorough duct sealing. In a 1950s Alamo Heights ranch with original galvanized ductwork, UV at the coil prevents the musty microbial issues that compound pollen allergies, while the purifier captures the pollen before it circulates. Combined installation typically runs $1,200-$1,850. We’ll assess your specific system layout and give you an exact quote before any work begins.
We use low-pressure fogging equipment with EPA-registered sanitizers formulated for mixed metal and flex systems, applied at concentrations and dwell times that won’t corrode galvanized steel or degrade residual flex-duct liner. In Alamo Heights’s older systems with rough interior surfaces and possible pinhole corrosion, we inspect first with camera to identify any metal too compromised for chemical treatment. Fragile sections get flagged for repair or replacement before sanitizing proceeds. The inspection itself is included in your service quote. Call (866) 347-2063 to schedule.
Yes. Flex duct absorbs odors into its porous liner, while metal duct holds odors primarily on surface deposits and in rough interior corrosion. In Alamo Heights homes with both materials, we use enzyme treatments for flex components and oxidation treatments for metal, matching the chemistry to the substrate. We also inspect transition points where odors often concentrate due to moisture accumulation from temperature differentials. Mixed-system odor removal typically runs $350-$495, with most jobs completed in one visit.
We work carefully with original retrofitted joints every week in Alamo Heights, and we inspect with camera before agitation to identify any connections too fragile for standard cleaning. Where we find compromised joints, we seal or support them before proceeding, or recommend repair if the connection won’t hold. Our Rotobrush equipment has adjustable torque settings for delicate older systems, and our technicians are trained to recognize the mixed flex-and-metal configurations common to 1960s colonial revivals in the 78209 area. The 90-Day Done Right Promise covers our work either way. Call (866) 347-2063 for a free inspection and honest assessment.
