Why San Marcos Homeowners Choose Bellows Air Duct & Vent Co. of Texas
We’ve been called to homes off Hopkins Street where the same family has lived for thirty years, and to rental units near Thorpe Lane where the tenant count is lost to memory. Both call us for the same reason: they want the job done right, and they don’t want to think about it again.
Our technicians know the difference between the flex-duct systems common in the university rental corridors and the rigid metal ductwork in older neighborhoods like Blanco Gardens. That matters because the cleaning approach changes, and so does what we find inside. We’ve pulled out cedar pollen layers thick enough to date, pet hair from animals the current tenant never owned, and mold colonies fed by the river-corridor humidity that settles into San Marcos ductwork differently than it does in drier Hill Country towns.
Every job starts with a camera inspection and ends with one. You see what we see, before and after. Our pricing is set before we lift a tool, and our 90-Day Done Right Promise means if something isn’t right, we make it right with no paperwork and no arguing. Calls to (866) 347-2063 are answered by a live person, 24 hours a day.
Air Duct Cleaning Services We Offer in San Marcos
Air Duct Cleaning
We clean the full supply and return duct network, registers, and grilles using Rotobrush and Nikro equipment. Every San Marcos job gets camera documentation before and after. Learn more about our Air Duct Cleaning in San Marcos.
Dryer Vent Cleaning
Lint accumulation in dryer vents is a leading cause of house fires, and San Marcos’s high humidity makes clogs form faster than in drier climates. We clear the full vent run and verify airflow with a meter. Learn more about our Dryer Vent Cleaning in San Marcos.
HVAC Cleaning
Blower motors, evaporator coils, and plenums collect the same debris as ductwork, and in San Marcos they do it across more than 220 cooling days per year. We clean the full air handler, not just the ducts. Learn more about our HVAC Cleaning in San Marcos.
Duct Repair & Sealing
The flex-duct common in San Marcos rental stock crimps, disconnects, and leaks at rates far above rigid metal systems. We repair or replace damaged sections and seal leaks with mastic, not tape that will fail - learn more about our Duct Repair & Sealing in San Marcos.
Air Quality & Sanitizing
For homes where mold or bacteria is present, or where occupants have respiratory sensitivities, we apply EPA-registered sanitizers after mechanical cleaning - see Air Quality & Sanitizing - San Marcos for details. We use this selectively, not as an upsell on every job.
Neighborhoods We Serve in San Marcos
Most San Marcos calls are scheduled same-day or next-day, depending on when you call. We regularly work in:
- Blanco Gardens - older owner-occupied homes with original metal ductwork
- Thorpe Lane corridor - dense student rentals with neglected flex-duct systems
- Hopkins Street area - mixed housing stock, often with additions that create ductwork puzzles
- Hays County growth corridor (78666 outskirts) - newer construction with post-build debris issues
- Downtown San Marcos - historic homes with retrofitted HVAC and unique access challenges
Why San Marcos’s Climate & Housing Affect Air Duct Cleaning
San Marcos sits directly on the Balcones Escarpment, ground zero for the Hill Country’s Ashe juniper pollen. From December through February, cedar counts routinely spike to levels that shut down outdoor activity for sensitive residents. That pollen doesn’t stay outside. It gets pulled into return vents, trapped in filters that are rarely changed in rental units, and layered into ductwork where it recirculates every time the system runs.
The other half of the San Marcos story is Texas State University’s 38,000 students and the rental market built to house them. Apartment complexes near campus and rental houses off Aquarena Springs Drive often see three or four tenant cycles between any duct attention. We’ve opened vents in these buildings and found cedar pollen stratified in visible bands, pet dander from animals long gone, and mold fed by the constant humidity of the San Marcos River corridor. The springs maintain 72°F water year-round, and that moisture permeates the air in ways drier Hill Country cities like Kerrville or Fredericksburg simply don’t experience. Ductwork here needs more frequent attention, not less, and the problems look different depending on whether you’re in a 1990s apartment box or a newer subdivision pushing toward Kyle, TX.

FAQs About Air Duct Cleaning in San Marcos
Most San Marcos homes fall between $350 and $650 for a complete single-system cleaning. Larger homes or properties with dual HVAC systems run higher.

Every three to five years for owner-occupied homes, but more frequently if you have allergies, pets, or live near the heavy cedar pollen zones along the Balcones Escarpment. Rental properties near Texas State often need attention between every tenant cycle, which rarely happens. If you’re moving into a previously rented unit in San Marcos, we recommend an inspection.
Yes, and we do it regularly in the Thorpe Lane and Aquarena Springs corridors. Flex-duct requires a lighter touch than rigid metal to avoid damage, and we always camera-inspect first to check for existing crimps or disconnections. If we find damage, we’ll show you and quote repair before proceeding.
Repair is almost always less expensive for isolated damage - typically $15-$35 per linear foot for sealing or section replacement. Full duct replacement in San Marcos runs into the thousands and is only justified when the system is extensively deteriorated or improperly sized. We’ll show you what we find and give you both options if replacement is a consideration. Call (866) 347-2063 to schedule a camera inspection.
We often schedule same-day or next-day in San Marcos, especially for respiratory urgency. Our phones are answered live 24 hours a day, and we’ll tell you honestly if we can get a technician to your ZIP code today - 78666 or 78667 - or if first thing tomorrow is the earliest slot. We don’t promise what we can’t deliver.
