Why Bellows Air Duct & Vent Co. of Texas Is Fresno’s Preferred Air Quality & Sanitizing Company
Fresno homeowners don’t have patience for bait-and-switch pricing anymore. Too many have opened their door to a low coupon, only to watch the bill triple once the truck is unpacked. We don’t work that way. Our price is the price, disclosed before a single tool is lifted.
Our reputation in Fort Bend County is built on return visits, not callbacks. The 90-Day Done Right Promise means if the work isn’t right, we make it right. No paperwork to file, no argument to win. It’s stamped on every job because Wade Kellerman put it there when he founded this company in 1984, and it’s non-negotiable still.
We carry professional-grade equipment from Rotobrush, Nikro, and Honeywell, the same brands serious HVAC contractors specify. Every job gets camera-inspected before and after, so you see what we see, not just take our word for it. Most Fresno appointments are completed in one visit. And when you call (866) 347-2063, a live person answers, day or night.
Our Air Quality & Sanitizing Services in Fresno
Mold Treatment
Fresno’s mold problem isn’t like mold in drier parts of Texas. The low-lying corridor near Mustang Bayou took on water during Hurricane Harvey in 2017, and that moisture wicked into attic-routed ductwork where it stays. The extreme Gulf Coast humidity keeps indoor moisture elevated year-round, so post-flood contamination compounds rather than dries out.
On a recent job near Mustang Bayou, a 1998 slab-foundation home had duct board interiors with standing-water staining and active mold from unaddressed Harvey moisture. Our crew used Rotobrush agitation and Abatement Technologies HEPA vacuums to strip the contaminated insulation, then applied a Guardsman antimicrobial sealant, eliminating the musty odor that had persisted for years. A typical mold treatment in Fresno runs $350-$650 depending on linear footage and contamination severity.
Bacteria Sanitizing
The same humidity that feeds mold breeds bacteria in your duct stream. Fresno’s HVAC systems cycle ten to eleven months a year, far more than in drier Texas cities, and all that airflow hours deposit biological debris that standard filters never catch. Our bacteria sanitizing service applies EPA-registered antimicrobial agents throughout the duct system, not just at the vents where it’s easy to reach. For a whole-home treatment in a typical Fresno three-bedroom, expect $275-$425.
Odor Removal
Musty, stale, or sour smells that return after cleaning usually mean the source was never fully eliminated. In Fresno’s 77545 homes, we find this constantly: surface-level cleaning that left active contamination deep in duct board or flex-duct lining. Our odor removal process targets the biological source with mechanical agitation, HEPA extraction, and sealing agents that prevent recurrence. Most Fresno odor jobs fall between $300-$500.
UV Light Installation
A UV-C lamp mounted at the coil or in the supply plenum kills mold and bacteria before they enter your living space. In Fresno’s humidity, this isn’t a luxury add-on. It’s a genuine defense against the persistent moisture that recontaminates cleaned ducts. We install Honeywell and Aprilaire UV systems sized to your air handler, typically $450-$750 installed with a two-year bulb life. For homes near Mustang Bayou or in the post-Harvey moisture zone, we recommend UV as standard complement to any mold treatment.

Trusted Brands We Service in Fresno
We stock and install equipment from Rotobrush, Nikro, Honeywell, and Aprilaire, brands that HVAC contractors specify when the job has to last. For Fresno customers, this means no waiting on parts shipped from Dallas or Atlanta. Our trucks carry the agitation brushes, HEPA vacuums, antimicrobial agents, and UV components needed to complete most jobs without a return trip. If your system uses a specific air purifier or UV housing, we’ll match it. If it’s obsolete, we’ll tell you straight and recommend a replacement that fits without modifying your plenum.
Common Air Quality & Sanitizing Problems We See in Fresno Homes
- Post-Harvey moisture trapped in attic duct board. Surface-level remediation in 2017 left duct interiors untouched. That moisture is still cycling spores through living spaces today, and standard filter changes never reach it.
- Under-insulated supply ducts dripping condensation. In 130°F Fresno attics, even slight insulation gaps cause exterior condensation that drips back inside the duct, feeding mold growth invisible from the vents.
- Mastic seals degraded by extreme attic heat. The 1990s-2010s tract homes in 77545 are aging into the window where seals separate, pulling unfiltered attic air directly into your breathing air.
- Heavy debris loads from near-constant system runtime. Fresno’s ten-to-eleven-month cooling season deposits far more dust, pollen, and biological material than systems in drier, milder climates accumulate.

FAQs - Air Quality & Sanitizing in Fresno
Yes. We camera-inspect every linear foot of accessible ductwork, and we specifically look for the standing-water staining and active mold growth that persists in Harvey-impacted homes near Mustang Bayou. Standard surface-level cleaning never reaches these interior duct board colonies. If we find it, we show you the footage and explain your options before any work proceeds. Call (866) 347-2063 to schedule, estimates are free.
The root cause was likely never eliminated. In Fresno’s humidity, mold returns within months if moisture sources, under-insulation, or contaminated duct board remain unaddressed. We identify and treat the source, seal with antimicrobial agents, and recommend UV installation where appropriate. Call (866) 347-2063 and we’ll diagnose why your previous cleanings didn’t stick.
In nearly all cases, yes. Fresno’s slab-foundation tract homes have attic-routed ductwork accessible through the ceiling hatch or garage entry. We use Rotobrush agitation and HEPA vacuum extraction through existing registers and main trunk access points. Drywall cutting is rare and only discussed if we find collapsed or separated ductwork that requires repair. Call (866) 347-2063 for a free assessment of your specific layout.
Yes, particularly here. Fresno’s persistent Gulf Coast moisture and near-constant system runtime create ideal conditions for biological regrowth. A properly sized UV-C lamp at the coil or in the supply plenum kills mold and bacteria before distribution, reducing the recontamination rate significantly. We typically see UV as essential, not optional, for homes in the post-Harvey moisture zone. Installed cost runs $450-$750. Call (866) 347-2063 to discuss sizing for your system.
We remove and dispose of contaminated duct board according to Texas environmental guidelines, then treat the remaining structure with antimicrobial sealant. If the damage is extensive, we’ll recommend repair or replacement options with upfront pricing before proceeding. Our Air Quality & Sanitizing team documents everything with before-and-after camera footage for your records. Call (866) 347-2063 to schedule remediation.
