We’ve been driving out to Highlands since 1984, back when the community was still filling in between the old Highway 90 corridor and the San Jacinto River bottomlands. Our office in Houston keeps technicians staged for the eastern suburbs, so we’re usually at a Highlands address within 45 minutes of a call. We know the difference between a post-Harvey rebuild off North Main Street and a 1960s pier-and-beam ranch on San Jacinto Street, and we know which ones are hiding problems that a standard cleaning won’t touch. That local knowledge matters when you’re deciding whether to treat, replace, or walk away from contaminated ductwork.
Why Bellows Air Duct & Vent Co. of Texas Is Highlands’s Preferred Air Quality & Sanitizing Company
Highlands sits directly adjacent to the Houston Ship Channel petrochemical corridor. Refineries, chemical plants, and industrial facilities in neighboring Baytown and the Channel area continuously emit airborne particulates, sulfur compounds, and industrial fallout that get drawn into residential HVAC systems at rates unmatched in suburban Houston markets. Compounded by the community’s position in the San Jacinto River floodplain, where Hurricane Harvey’s 2017 catastrophic flooding submerged homes and saturated ductwork, many systems here carry a dual burden of industrial residue and entrenched post-flood mold contamination that requires far more aggressive remediation than a standard Houston metro cleaning job.
We’ve built our reputation in Highlands on showing homeowners exactly what they’re breathing. Every job starts and ends with a camera inspection of the ductwork. You see the contamination before we touch it, and you see the results after we’re done. No claims without proof.
Our 90-Day Done Right Promise applies to every Highlands job. If the work isn’t right, we return at no charge with no paperwork required. Wade Kellerman put that guarantee in place when he founded the company in 1984, and it’s still how we operate.
Calls are answered by a live person, 24 hours a day. Not a voicemail, not an app. When you’re dealing with mold spreading through your vents or industrial odors cycling through the house, you want to talk to someone who can dispatch a technician, not leave a message and hope.
Our Air Quality & Sanitizing Services in Highlands
Mold Treatment
Mold treatment in Highlands homes typically costs $350-$850 for whole-home duct remediation, depending on the extent of contamination and whether the ductwork is accessible. The San Jacinto River bottomlands create a persistently high-humidity microclimate well above even typical Houston levels, meaning HVAC systems run nearly year-round and continuously pull moisture-laden air through ducts. Biological growth isn’t a seasonal problem here. It’s constant.
We recently sanitized a 1950s ranch home on San Jacinto Street where post-Harvey mold colonies lay hidden in fiberglass duct runs that were never properly remediated. Using our Rotobrush system with Abatement Technologies HEPA filtration, we removed entrenched Aspergillus and re-sealed the ducts with antimicrobial coating to prevent recurrence in the river-bottom humidity. The homeowner had lived with a persistent cough for two years before the camera inspection revealed what wiping down vents never could.

Bacteria Sanitizing
Bacteria sanitizing in Highlands runs $200-$450 for standard residential systems, with larger or more contaminated systems at the higher end. Industrial fallout from nearby refineries doesn’t just clog filters. It creates a nutrient-rich film inside ductwork where bacterial colonies establish themselves and recirculate with every AC cycle. Standard duct cleaning removes debris. It doesn’t kill what’s living on the surface.
We apply EPA-registered antimicrobial treatments after mechanical cleaning, targeting the bacterial load that industrial particulates support. In Highlands, this step isn’t optional. It’s the difference between clean ducts and sanitized ducts.

Odor Removal
Odor removal in Highlands homes starts at $275 for localized treatment and ranges to $600-$900 when industrial sulfur compounds or flood-related mustiness have saturated the entire system. The petrochemical corridor produces a distinctive chemical signature that standard deodorizers mask temporarily but don’t eliminate. We use oxidation and carbon-based treatments that break down the molecular source of the odor rather than covering it.
Homes near the 77562 ZIP code boundary with Channelview often report the strongest industrial odors, particularly when prevailing winds carry emissions from the Ship Channel facilities. We’ve developed specific protocols for these properties that go beyond standard odor treatment.

UV Light Installation
UV light installation in Highlands typically costs $800-$1,400 including the lamp, housing, and professional installation with duct sealing. The high-humidity San Jacinto microclimate allows mold and mildew to regrow within months if cleaning doesn’t include a UV light or antimicrobial treatment. A properly installed UV-C lamp in the plenum kills airborne mold spores and bacteria before they colonize the coil or duct surfaces.
We specify Honeywell and Aprilaire UV systems sized to the HVAC capacity, not generic one-size units. In Highlands, undersized UV is wasted money. The humidity and biological load here demand adequate dosage and proper placement.

Trusted Brands We Service in Highlands
Our technicians carry Rotobrush mechanical cleaning systems and Nikro HEPA vacuums on every Highlands truck, alongside Honeywell and Aprilaire filtration and UV components. We don’t show up hoping your system matches what we have. We stock the parts that serious HVAC contractors specify, and we bring them to your door. That means most Highlands jobs finish in one visit, whether we’re treating mold in a 1940s ranch near Main Street or installing UV protection in a post-Harvey rebuild off Wallisville Road.
Common Air Quality & Sanitizing Problems We See in Highlands Homes
- Industrial fallout clogging filters within weeks. The petrochemical corridor produces particulate loads that overwhelm standard 1-inch filters. Homeowners in Highlands often don’t realize their filters are failing until the HVAC efficiency drops or odors appear. We recommend upgraded filtration and duct sealing with HEPA-grade media for properties in the heaviest exposure zones.
- Post-Harvey flooded ductwork that was “dried out” without professional sanitizing. A large share of Highlands ductwork was submerged or flood-saturated during Harvey’s San Jacinto River overflow. Many homeowners had systems dried out and left in place rather than replaced. We routinely discover established mold colonies hidden deep in duct runs that were never remediated. A failure mode essentially unique to this river-bottom community.
- Accelerated biological regrowth due to river-bottom humidity. The San Jacinto floodplain microclimate keeps duct surfaces moist enough for mold and mildew to establish within weeks of cleaning if no preventive treatment is applied. UV lights or antimicrobial coatings aren’t upsells here. They’re necessary maintenance.
- Fragile aging ductwork in pre-1970s homes. Highlands developed largely in the 1940s through 1970s as working-class housing for petrochemical industry workers, leaving a stock of modest ranch-style and pier-and-beam homes with aging flex-duct or early fiberglass duct systems. These systems are both heavily contaminated and fragile to service. Our technicians assess structural duct integrity before any aggressive cleaning begins.

FAQs - Air Quality & Sanitizing in Highlands
Industrial facilities upwind of Highlands emit particulates and sulfur compounds that infiltrate homes through HVAC intakes and envelope leaks, loading filters and duct surfaces with contaminants standard suburban homes don’t face. We address this with upgraded filtration, sealed ductwork, and more frequent service intervals than typical Houston metro recommendations. Call (866) 347-2063 to schedule an assessment of your exposure level.
Yes. Drying alone doesn’t eliminate mold spores or bacterial colonies established during submersion, and we’ve found active contamination in many Highlands systems that were “dried out” and left in place. Our camera inspection will show you what’s still living in the ductwork. Estimates are free. Call (866) 347-2063.
UV-C lamps kill airborne mold spores and prevent colony formation on coils and duct surfaces, but they don’t reduce humidity. In Highlands, we recommend UV installation paired with proper duct sealing and, in some cases, whole-home dehumidification to address the root moisture problem. A UV light without moisture control is half a solution in this climate. Call (866) 347-2063 for a system-specific recommendation.
Rapid dust accumulation in Highlands usually indicates two problems: inadequate filtration for the industrial particulate load, and leaks in the return ductwork pulling unfiltered air from attics or crawl spaces. Our camera inspection identifies both issues, and we seal leaks before they recontaminate the system. Call (866) 347-2063 for a diagnosis.
We can, but we assess structural integrity first. Highlands has many pre-1970s homes with aging flex-duct or fiberglass systems that won’t withstand aggressive mechanical cleaning. When we find fragile ductwork, we recommend gentler methods or discuss replacement options before proceeding. Our Air Quality & Sanitizing team won’t damage your system to clean it. Call (866) 347-2063 to discuss your specific home.
