Why Bellows Air Duct & Vent Co. Is Austin’s Preferred Air Quality & Sanitizing Company
We’ve been in business over 42 years, and Austin has been part of our service territory for decades. Homeowners in Wells Branch, Anderson Mill, and along South Congress know our trucks. They also know our 90-Day Done Right Promise - if the work is not right, we return at no charge with no paperwork required.
Our reputation in Austin is built on showing, not telling. Every job gets camera-inspected before and after. You see what we see. That matters in a market where discount operators bait with low phone quotes, then change prices at the door. We disclose one honest price before a single tool is lifted. The number on the phone is the number on the invoice.
Response time to Austin neighborhoods is typically same-day or next-day, and our technicians carry the equipment to complete most sanitizing and air quality jobs in one trip. That’s important for working homeowners who don’t want to schedule a second visit.
Ray Castillo, who leads Bellows Air Duct & Vent Co., set the standard we still follow: no scare tactics, no bait coupons, just work that doesn’t need to be called back.
Our Air Quality & Sanitizing Services in Austin
Allergen Reduction
Austin sits in the heart of Ashe juniper country, and the December-February Cedar Fever season releases some of the densest airborne pollen loads in North America. The pollen is fine enough to bypass standard 1-inch filters and cake duct interiors. We see it every February and March - the week after the first hard cedar-pollen rain that ends the season is consistently our highest-call-volume stretch of the year. Homeowners who have lived through one Cedar Fever season and connected their misery to contaminated ductwork become our most loyal recurring customers. Our allergen reduction service uses professional-grade HEPA extraction and antimicrobial treatment to remove pollen, dust mite debris, and pet dander from duct interiors, not just the vents you can see.
Mold Treatment
Austin’s humidity spikes during spring and fall create condensation risk inside ductwork, especially on oversized AC systems common in the rapid-growth suburbs built from the 1990s through the 2000s. That moisture, combined with 140-160°F attic heat degrading flex duct joints, creates the exact conditions for mold colonization. Our Mold Treatment isn’t a surface wipe. We locate the source, treat affected duct interiors with EPA-registered antimicrobial agents from Abatement Technologies, and verify clearance with camera documentation. In older Austin homes near 78702-78705, we frequently find decades of construction debris and rodent intrusion inside original flex duct or early sheet-metal runs that have never been serviced.
UV Light Installation
Should you install a UV light in your Austin home’s HVAC system? For many homeowners here, yes - especially if you’re fighting recurring microbial growth or living with allergy sufferers. We install UV-C germicidal lights from leading manufacturers, positioned at the evaporator coil and return plenum where they can suppress mold and bacteria growth on wet surfaces. Austin’s combination of high cooling loads and humidity swings makes coil mold a persistent problem that filters alone won’t solve. A properly sized UV system runs silently, requires annual lamp replacement, and works continuously while your system operates.
Bacteria Sanitizing
Whole-home bacteria sanitizing targets the microbial load that builds in ductwork after water intrusion, rodent activity, or simply years of organic accumulation. We use fogging and contact application methods with hospital-grade sanitizers, applied after mechanical cleaning removes the debris that shields bacteria. This is not a DIY spray job. Proper application requires controlled dwell time, ventilation management, and post-treatment verification.
Odor Removal
Persistent HVAC odors in Austin homes usually trace to one of three sources: mold or mildew in the coil or pan, rodent activity in attic ductwork, or volatile organic compounds from construction materials in flipped properties. We find the source first, then treat it. Masking agents don’t work long-term, and we don’t use them.
Air Purifier Install
For Austin homeowners with severe allergy concerns, we install whole-home air purifiers from Aprilaire, including units with MERV 13 and higher filtration that capture particles down to 1.0 micron. That’s the difference between standard equipment and what actually helps during Cedar Fever season.

Trusted Brands We Service in Austin
We specify professional-grade equipment from Abatement Technologies, Aprilaire, and Rotobrush - the same brands serious HVAC contractors use, not retail-grade units. Our technicians stock replacement lamps, filters, and treatment chemicals for Austin customers, so most maintenance and upgrade work completes in one visit. For UV light installations, we size the unit to your system’s airflow and coil dimensions, not guess based on square footage. For air purifiers, we match the MERV rating and pressure drop to what your existing blower can handle without strain. That’s the difference between a proper install and a box hung on a duct.
Common Air Quality & Sanitizing Problems We See in Austin Homes
- Mountain cedar pollen overwhelming standard filtration. Standard 1-inch fiberglass filters capture large particles but miss the sub-10-micron pollen that defines Cedar Fever. It passes through, coats evaporator coils, and accumulates in duct interiors until the next season recirculates it. We see this in homes from Hornsby Bend to Jollyville.
- Mold from condensation in oversized AC systems. The 1990s-2000s building boom in Austin suburbs installed many systems too large for the ductwork, causing short cycles and incomplete dehumidification. Moisture lingers in ducts, especially in spring and fall shoulder seasons. Standard cleaning without antimicrobial treatment leaves the root problem intact.
- Attic flex duct degradation from extreme heat. Austin attics routinely hit 140-160°F in summer, breaking down flex duct lining and causing joints to separate. Unconditioned attic air and insulation particles draw directly into the supply stream. Sanitizing without inspecting for these failures means recontamination from the same source.
- Rodent intrusion in older ranch homes. Central Austin’s 1950s-1970s housing stock, particularly in neighborhoods near teardown-and-renovation activity, often contains original ductwork that has never been sealed against rodent access. We find nesting debris, droppings, and chewed flex duct that requires removal and replacement, not just cleaning.

FAQs - Air Quality & Sanitizing in Austin
Cedar Fever season releases pollen fine enough to bypass standard filters and accumulate in ductwork, making February and March our busiest months for allergen-related calls. Homeowners who experience one full season and connect their symptoms to recirculating indoor air typically become annual maintenance customers. The most effective response is HEPA-level duct cleaning followed by upgraded filtration or whole-home air purification. Call (844) 685-6342 to schedule before the next surge.
Yes, if you have recurring mold on your evaporator coil, persistent musty odors, or allergy sufferers in the home. Austin’s humidity and heavy cooling loads create ideal conditions for coil mold that filters cannot address. We install UV-C lamps sized to your specific coil and airflow, with annual replacement schedules to maintain effectiveness. Most installations run $350-$550 and are completed in one visit.
A whole-home unit with MERV 13 or higher filtration, such as the Aprilaire systems we install, captures particles at the 1.0-micron level where mountain cedar pollen operates. Portable units only treat single rooms and rarely move enough air to matter. Whole-home systems integrate with your existing ductwork and run whenever the blower operates. In the 78704 neighborhood near South Congress, we cleared a 1970s ranch home’s supply ducts of inch-deep mountain cedar pollen and rodent debris, then installed an Aprilaire whole-home air purifier with a MERV 13 filter to keep the next Cedar Fever season from recirculating through the home.
After professional removal and exclusion, ducts should be cleaned and sanitized immediately, then inspected annually for two years. Austin’s older ranch homes in central ZIP codes often have original ductwork with gaps that re-admit rodents if not properly sealed. We check for new activity during routine maintenance and re-treat if evidence appears. Call (844) 685-6342 for an inspection and upfront quote.
Our Mold Treatment reduces Aspergillus and other common attic duct molds to non-detectable levels per EPA guidelines, verified with post-treatment inspection. Complete “removal” is technically impossible - mold spores are everywhere - but we eliminate the active colonization and moisture source that allows growth. In Austin’s heat-degraded flex duct systems, we also identify and repair separated joints that draw humid attic air, or we recommend duct replacement if the material is too deteriorated. The 90-Day Done Right Promise covers our work: if mold returns in treated areas, we return at no charge.
