Why Bellows Air Duct & Vent Co. of Texas Is Lakeway’s Preferred Air Quality & Sanitizing Company
We’ve built our reputation in Lakeway the same way we have everywhere else: by showing up when we say, disclosing one honest price before lifting a single tool, and standing behind the work with our 90-Day Done Right Promise in writing. Wade Kellerman has led this company since its founding in 1984, and that same steady hand guides how we treat every Lakeway homeowner who calls.
Our technicians are background-checked, uniformed, and equipped with camera inspection systems that document your duct condition before and after every job. No claim without proof. Lakeway customers tell us they appreciate that we don’t bait them with a low coupon and then change the price at the door - the number you hear on the phone is the number on the invoice. Calls are answered by a live person 24 hours a day, not a voicemail tree, because we know air quality problems don’t wait for business hours.
We also know the local terrain. The climb up from Bee Cave, the winding streets off Lohmans Crossing, the humidity pockets near the lake - this geography affects how your ducts perform and how we approach each job.
Our Air Quality & Sanitizing Services in Lakeway
Allergen Reduction
Lakeway sits squarely inside the Ashe juniper belt of the Texas Hill Country, making it ground zero for Cedar Fever season, typically December through February, when mountain cedar pollen reaches some of the highest concentrations recorded in the continental US. That microscopic pollen is pulled through return-air intakes and accumulates heavily in ductwork, giving Lakeway homeowners a uniquely acute, annually recurring reason to schedule duct cleaning that suburban neighbors in Round Rock or Cedar Park - without the dense juniper canopy - simply don’t share at the same intensity. We use Rotobrush agitation and HEPA extraction to remove trapped pollen layers from supply plenums and trunk lines, then apply targeted treatments to reduce re-entrainment. For homes near active construction along 78738 corridors, we also address the limestone and caliche dust that infiltrates through cracked windows during cooler months.

Mold Treatment
The proximity to Lake Travis creates localized humidity swings that raise the risk of microbial and mold growth inside ductwork, particularly in summer when AC systems run almost continuously and condensation can collect in poorly insulated supply runs. We’ve treated mold in Lakeway ducts where fiberglass liner had become a breeding ground, and in metal trunk lines where cold-air stratification met warm attic air. Our process includes camera identification of growth locations, mechanical removal with Nikro equipment, and application of Abatement Technologies antimicrobial fog to treated surfaces. We don’t just mask the problem - we document where it was, what we did, and what condition your system is in when we leave.

Odor Removal
Musty, sour, or chemical odors in Lakeway homes often trace back to the intersection of lake humidity, pollen accumulation, and construction dust layering in ductwork. The ongoing residential construction across 78738 generates persistent limestone and caliche dust that infiltrates homes during the cooler months when windows are cracked, adding a construction-dust layer on top of the seasonal pollen load. That combination can produce odors that standard filter changes won’t touch. We source odors with camera inspection, then apply oxidation or encapsulation treatments depending on the contaminant type. No cover-up scents - we eliminate what causes the smell.

UV Light Installation
UV-C systems installed at the air handler or supply plenum can suppress mold and bacterial growth on wet coils and in drain pans, which matters in Lakeway’s humidity-prone environment. We size and position UV units from Honeywell and Aprilaire based on your system’s airflow and duct geometry, not with a one-size-fits-all bracket. For the large multi-zone systems common in 2000s-2020s Lakeway custom homes, we may recommend multiple units to maintain effective irradiance across longer duct runs.

For Lakeway customers, this means we don’t need to order parts from Houston or Austin and make you wait. Our trucks are stocked for same-day completion on most jobs, whether we’re treating a compact 1970s ranch near the original Lakeway Inn site or a 6,000-square-foot custom build off The Hills Drive with five zones and a dedicated media room.
Common Air Quality & Sanitizing Problems We See in Lakeway Homes
- Collapsed filters from cedar pollen overload. Local HVAC techs know that during cedar season, Lakeway return grilles on the original 1970s resort homes - many of which were sized for much smaller systems before additions were built - become so clogged with cream-colored juniper pollen that filters collapse inward within two to three weeks, pushing unfiltered air directly into the air handler and coating supply plenum walls; post-cedar duct cleaning calls spike sharply every February in this ZIP.
- Recirculated particulate in tight spray-foam homes. Lakeway has two distinct tiers: the original 1960s-70s resort-era homes with simpler, shorter duct layouts, and a dominant wave of 2000s-2020s luxury Hill Country builds featuring large square footage, multi-zone systems, and long duct runs that accumulate significantly more debris and pollen over greater surface area. Many of the newer custom homes also use tighter spray-foam envelopes, which reduces outside-air dilution and means indoor particulate - including cedar pollen - recirculates through ducts more aggressively than in leakier older construction.
- Condensation-driven mold in lake-humidity zones. The proximity to Lake Travis creates localized humidity swings that raise the risk of microbial and mold growth inside ductwork, particularly in summer when AC systems run almost continuously and condensation can collect in poorly insulated supply runs. We see this most often in supply branches running through vented attics or crawl spaces where insulation has settled or been disturbed.
- Construction dust infiltration from 78738 development. The ongoing residential construction across 78738 also generates persistent limestone and caliche dust that infiltrates homes during the cooler months when windows are cracked, adding a construction-dust layer on top of the seasonal pollen load. This abrasive dust accelerates wear on blower motors and coats duct interiors with a fine grit that standard vacuuming won’t fully remove.
Pricing for Air Quality & Sanitizing in Lakeway, TX
A typical whole-system duct sanitizing in Lakeway runs $350-$850, depending on system size, contamination level, and accessibility. Mold treatment for localized growth in a single trunk or plenum typically falls between $450-$720. UV light installation ranges from $680-$1,200 per unit, including electrical connection and placement optimization. Odor removal treatments start around $280 for standard oxidation and run to $550 for multi-source problems requiring camera diagnosis and staged application.
What moves the number: square footage and zone count (those 2000s+ custom homes with long duct runs take longer), the degree of pollen or mold buildup we find on camera, and whether we need to access ductwork through finished spaces. We show you the camera footage before we quote, and the price we state is the price on the invoice. No bait, no change at the door. We also honor our standing offers: $50 off any repair over $250, a free second opinion on any written estimate, our $89 seasonal tune-up, and a permanent 5% senior and veteran discount.

FAQs - Air Quality & Sanitizing in Lakeway
Most Lakeway homeowners with allergies or respiratory sensitivity benefit from a full duct cleaning and sanitizing in late January or early February, after the peak pollen load has accumulated but before sustained warm weather reactivates mold spores. Homes with 1970s-era return grilles or spray-foam envelopes may need more frequent filter changes - every two to three weeks during peak season - and a mid-season inspection if symptoms worsen. Call (866) 347-2063 and we’ll look at your system on camera to give you a schedule that fits your home, not a generic calendar.
Yes. The original 1970s homes near the lake typically have shorter, simpler duct runs with metal trunk and branch construction, but their return grilles were often undersized for later HVAC upgrades and clog faster with pollen. Newer custom builds have longer duct surfaces, more zones, and tighter envelopes that trap and recirculate particulate. We adjust our equipment and treatment approach accordingly - aggressive agitation and filter upsizing for the older homes, multi-zone sequencing and fresh-air integration advice for the newer ones. Wade Kellerman has overseen both types for decades, and our crew knows what to look for before we start.
UV-C light does not filter or trap pollen - it’s designed to suppress mold, bacteria, and viral growth on wet coils and in drain pans. Where it helps Lakeway homeowners is by preventing the mold and biofilm that grow on pollen-coated coils during humid summer months, which can worsen allergy symptoms even after cedar season ends. For pollen itself, we recommend upgraded MERV filtration combined with regular duct cleaning. We can install both, sized to your system, with upfront pricing before we start.
The localized humidity around Lake Travis creates conditions where condensation forms in supply runs, especially where insulation has compressed or where ducts pass through vented attics. That moisture, combined with pollen and dust, feeds mold growth that standard operation won’t dry out. We see this most in Lakeway homes with systems that run continuously from May through October. Camera inspection reveals the location and extent; we treat with mechanical removal and antimicrobial application, then advise on insulation or airflow corrections to prevent recurrence.
It is. The caliche and limestone dust generated by ongoing construction across 78738 is fine, abrasive, and alkaline. It infiltrates through window gaps and door seals during cooler months, layers onto duct interiors, and accelerates wear on blower motors and bearings. More critically, it provides a mineral substrate that traps pollen and organic material, creating compacted deposits standard vacuuming won’t remove. We use Rotobrush agitation and HEPA extraction to break loose and remove these layers, then inspect with camera to confirm clean surface.
