Why Bellows Air Duct & Vent Co. Is Lago Vista’s Preferred Air Quality & Sanitizing Company

We’ve built our reputation in Lago Vista one hillside driveway at a time. Our Air Quality & Sanitizing team knows the difference between a year-round residence on Lohman Ford Road and a weekend place off Boggy Ford Road that’s been sealed up since deer season. That local knowledge matters because the problems are different, and so are the solutions.

Homeowners in Lago Vista tell us they chose us after getting a low-ball quote from a coupon outfit that showed up with a shop vac and no camera. We don’t work that way. Every job gets a camera inspection before and after, so you see what was in your ducts and you see that it’s gone. Our 90-Day Done Right Promise is stamped on every invoice: if it’s not right, we make it right, no paperwork, no arguing.

Most Lago Vista calls get a technician same day or next day. We understand that when you’re driving up from Austin or Houston for the weekend and the house smells like a cave, you don’t want to wait until Tuesday. Our office answers live at 2 a.m. on a Saturday because we’ve been doing this long enough to know that duct problems don’t follow business hours.

Our Air Quality & Sanitizing Services in Lago Vista

Allergen Reduction

Lago Vista sits in the heart of Texas’s Ashe juniper belt, making it ground zero for “cedar fever” - the December through February mountain cedar pollen explosion that is among the heaviest in the entire country. Because a significant share of Lago Vista homes are part-time lake and vacation properties that sit with HVAC systems idle for weeks, then run hard when owners arrive, duct systems accumulate dense loads of cedar pollen, caliche limestone dust, and mold spores before they’re ever circulated. Our allergen reduction service uses Rotobrush mechanical agitation plus HEPA vacuum extraction to remove these deposits from duct interiors, not just blow them around. We serviced a 1980s hillside cabin on Creekview Drive that had been closed since November. When the owner flipped the heat on in March, a cloud of cedar pollen and caliche dust blew from every register. Our Rotobrush system extracted nearly two pounds of fine pale-yellow residue from the flex-duct and return plenum, and we installed a Honeywell UV light in the attic air handler to prevent mold regrowth.

Mold Treatment

The Hill Country microclimate around Lake Travis combines high UV attic temperatures that routinely exceed 140°F in summer, periodic humidity spikes off the lake, and heavy winter pollen loads. This combination simultaneously breaks down duct insulation and creates conditions for mold growth in evaporator coils and drain pans. Our mold treatment applies EPA-registered antimicrobial through mechanical fogging equipment, reaching the full duct run including the dead spots behind plenum corners where mold colonies start. In Lago Vista’s older homes with original fiberglass duct liner, we inspect first with our camera to determine whether the liner has degraded past the point of treatment. Sometimes cleaning and treating is the right call. Sometimes the liner is shedding fibers and needs replacement. We’ll show you on camera and give you an honest recommendation either way.

UV Light Installation

UV lights make particular sense in Lago Vista’s climate. The same vacation-home neglect that lets cedar pollen accumulate also allows mold and bacteria to establish colonies on wet evaporator coils during the humid months. A properly installed UV-C lamp in the air handler kills mold spores and bacteria at the source, before they circulate. We specify Honeywell and Aprilaire UV systems, sized to the air handler capacity, with annual bulb replacement schedules that match Lago Vista’s heavy-use summer season. For homes that sit empty weeks at a time, we also recommend a UV light with a continuous low-power setting that maintains surface sterilization without running the full HVAC system. The installed cost for a single-lamp UV system in a typical Lago Vista residential air handler runs $380 to $520, including the lamp, mounting, and electrical connection.

Bacteria Sanitizing

Bacteria sanitizing goes beyond mold treatment to address the full spectrum of biological contaminants that can colonize duct systems. In Lago Vista, we see this need most often in homes where the evaporator coil has been caked with pollen and dust for multiple seasons, creating a biofilm that standard cleaning won’t touch. Our bacteria sanitizing service applies a hospital-grade disinfectant fogged through the complete duct system, with dwell time calculated to the cubic footage of your home. The service runs $320 to $480 for most Lago Vista homes between 1,800 and 3,500 square feet.

Odor Removal

Musty, stale, or “closed-up” odors in Lago Vista vacation homes usually trace to one of three sources: mold in the evaporator cabinet, rodent activity in crawlspace flex-duct, or accumulated pollen and dust that has begun to decompose. We find the source with camera inspection, eliminate it, then treat the duct system with an oxidizing deodorizer that neutralizes odor molecules rather than masking them. Odor removal as a standalone service runs $250 to $400; when combined with full duct cleaning, it’s typically $150 to $225 additional.

Air Purifier Install

Whole-home air purifiers installed at the air handler provide continuous filtration for homes where occupants have allergies, asthma, or sensitivity to the fine particulates that Lago Vista’s cedar season produces. We install Aprilaire and Honeywell media air cleaners with MERV 13 to MERV 16 filters, sized to your system’s airflow capacity. Installed cost ranges from $450 to $780 depending on filter cabinet size and whether duct modification is needed for the older plenums common in 78645 homes.

Trusted Brands We Service in Lago Vista

We carry professional-grade equipment and replacement components from Rotobrush, Nikro, and Abatement Technologies - the same brands serious HVAC contractors specify, not the consumer-grade units sold at big-box stores. For UV light and air purifier installations, we stock Honeywell and Aprilaire components in our service vehicles, which means most Lago Vista jobs are completed in a single visit without waiting for parts to ship. Our technicians are trained on each manufacturer’s installation requirements, and we document serial numbers and installation dates for warranty registration. If something fails during our 90-Day Done Right Promise period, we handle the manufacturer warranty claim ourselves. You don’t call a 1-800 number. You call us.

Common Air Quality & Sanitizing Problems We See in Lago Vista Homes

• Fiberglass duct liner degrades in 140°F+ attic temps. Most residential construction in 78645 includes ductwork routed through extremely hot unconditioned attic spaces where fiberglass duct liner degrades faster than in flatter, shadier markets. The degraded liner sheds glass fibers and traps cedar pollen that turns into a biological aerosol when the system runs. We inspect with camera first to determine whether liner replacement is needed.
• Flex-duct in crawlspaces under lakefront homes gets damaged by rodents. Torn flex-duct allows caliche dust and mold spores to bypass filters entirely, pulling unfiltered attic or crawlspace air directly into the living space. We repair or replace damaged sections and seal entry points.
• Vacation-home owners skip seasonal filter changes. By spring, the evaporator coil is caked with yellow cedar residue, reducing airflow and breeding bacteria. Our seasonal tune-up - $89 - includes coil inspection and filter replacement with the correct MERV rating for your system.
• Technicians working Lago Vista regularly find return-air plenums coated in pale-yellow cedar pollen residue. This pattern is almost nonexistent in Austin’s urban core but routine in this lakeside Hill Country ZIP, particularly in homes closed from Thanksgiving through February. The pollen is fine enough to pass through standard filters and recirculate until mechanically removed.
