Leon Valley isn’t a drive-by suburb for us. We know the housing stock here: the 1960s and 1970s ranch tracts that filled in when this was still unincorporated Bexar County. Those homes were built with fiberglass duct board and first-generation flex duct that has now seen 50+ summers in attics that hit 140°F. We’ve cleaned, repaired, and replaced more of that original ductwork than we can count. When we say we understand what your system is dealing with, we mean we’ve been inside hundreds of homes just like yours.

Our Air Duct Cleaning Services in Leon Valley
Residential Duct Cleaning
Most of our Leon Valley work is in single-family ranch homes built between 1965 and 1985. These systems have specific needs. Original fiberglass duct board delaminates under decades of thermal cycling. Flex duct sags and crushes. We clean what’s salvageable and tell you straight when it’s time to replace. Our Air Duct Cleaning team uses Rotobrush and Nikro equipment designed for residential systems, not oversized commercial gear that damages older ductwork. A typical Leon Valley residential cleaning runs $350-$650 depending on system size and accessibility.
Commercial Duct Cleaning
Leon Valley’s commercial core along Bandera Road and the smaller professional buildings near the intersection of Evers and Huebner need scheduled maintenance that doesn’t shut down operations. We work evenings and weekends when necessary, and we provide before-and-after video documentation for property managers and lease compliance. Commercial systems in Leon Valley typically range from $800-$2,400 depending on square footage and HVAC configuration.
Supply Duct Cleaning
The supply side is where your conditioned air reaches your rooms. In Leon Valley’s older homes, we frequently find supply registers clogged with degraded fiberglass particles from delaminated duct board, or blocked by decades of accumulated caliche dust drawn through seam gaps. We agitate and extract debris with professional-grade equipment, then verify clear airflow with camera inspection. Supply-only cleaning in Leon Valley runs $200-$400 when the return side is in good condition.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit. In Leon Valley’s 1960s-70s tract homes, undersized return chases are epidemic. They create negative pressure that sucks unconditioned attic air through every gap and seam, bringing in fiberglass insulation particles, caliche dust, and whatever else is in your ceiling. Cleaning the return side helps, but we always inspect for this structural problem. Return duct cleaning in Leon Valley typically costs $250-$450.
Full System Cleaning
This is what most Leon Valley homeowners actually need. We clean supply and return ducts, the main trunk lines, the plenum, and accessible coils. We camera-inspect every section. If we find delaminated duct board or crushed flex, we flag it and give you repair options with upfront pricing. Full system cleaning in Leon Valley runs $550-$850 for a typical 1,500-2,500 square foot home. Most jobs take 3-5 hours.
Video Inspection
Every Bellows job includes video inspection before and after. In Leon Valley, this matters more than most places. We’ve documented delaminated duct board that homeowners didn’t know was shedding fibers into their air. We’ve recorded return chases pulling visible attic debris. You get the footage. It’s your proof of what was actually in there and what we removed. Standalone video inspection for Leon Valley homeowners who want a second opinion on another company’s work runs $150-$250.

Trusted Brands We Service in Leon Valley
We run professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies - the same brands serious HVAC contractors specify for duct cleaning and remediation. For Leon Valley homes with older systems, we stock compatible fittings and transition pieces for duct board, flex duct, and metal trunk lines so repairs don’t stretch across multiple visits. If your system needs a component we don’t carry, we source it fast through our San Antonio supply house relationships. Most parts arrive next day, and we don’t charge you for return trips caused by our own inventory gaps. That’s part of the square deal.
Common Air Duct Cleaning Problems We See in Leon Valley Homes
- Original fiberglass duct board delaminating under extreme attic heat. Leon Valley attics regularly exceed 140°F in summer. After 50+ years, the resin binding fiberglass duct board fails, releasing fine glass fibers into your airstream. We see this constantly in homes near Grissom and Huebner. Cleaning helps temporarily, but delaminated board usually needs replacement.
- Undersized return chases creating negative pressure. The 1960s-70s ranch tracts that dominate Leon Valley were built with return air pathways too small for modern HVAC loads. Your system literally pulls attic air through gaps, bringing caliche dust and insulation particles into your supply. We identify this with pressure testing and camera inspection, then recommend proper solutions.
- Mountain Cedar pollen trapped in aging ductwork. The San Antonio metro, including Leon Valley, experiences North America’s worst Mountain Cedar (Ashe juniper) pollen events every December through February. If your HVAC runs during cedar season, that pollen loads into ducts and recirculates for months. Cleaning after cedar season is essential for homes with respiratory sensitivities.
- Crushed or disconnected flex duct in original installations. First-generation flex duct in Leon Valley homes has often sagged, been damaged by rodents, or pulled loose at connections. We find this behind walls and in attics during camera inspection. Sometimes cleaning isn’t the issue - it’s airflow restoration through proper reconnection and support.

FAQs - Air Duct Cleaning in Leon Valley
Mountain Cedar pollen is among the most concentrated airborne allergens in North America, and Leon Valley sits directly in the impact zone every December through February. If your HVAC runs during cedar season, pollen loads into your ductwork and recirculates for months after the trees stop releasing. We recommend scheduling duct cleaning in March or April, immediately after cedar season ends, to remove trapped pollen before summer AC use begins. Call (844) 685-6342 to book post-cedar cleaning - estimates are free.
Sometimes, but often the duct board itself is the problem. Original fiberglass duct board in Leon Valley’s 1960s-70s homes has typically delaminated after 50+ years of thermal cycling in 140°F attics. Cleaning removes surface debris, but it doesn’t restore failed resin binding. We camera-inspect first. If the board is intact, we clean carefully with equipment sized for older systems. If it’s delaminating, we quote replacement with modern insulated flex duct. On a job near the intersection of Grissom and Huebner, we found a 1972 ranch home where the original fiberglass duct board had delaminated so badly that the supply registers were blowing fine fiberglass dust. We recommended a full retrofit to insulated flex duct, which eliminated the indoor air quality issue and restored proper airflow. Call (844) 685-6342 for inspection and honest guidance.
It means your system is starving for return air and pulling unconditioned attic air through every gap and seam to compensate. Leon Valley’s 1960s-70s ranch tracts were built with return pathways too small for the HVAC loads they now carry. The negative pressure draws caliche dust, fiberglass particles, and attic heat directly into your supply side. We test for this with pressure gauges and camera inspection. Cleaning helps, but the real fix is enlarging or adding return capacity. We explain what we find and give you repair options with upfront pricing. Call (844) 685-6342 for a full system evaluation.
For Leon Valley’s climate and housing stock, we recommend every 3-5 years for homes with modern ductwork, and every 2-3 years for homes with original 1960s-70s systems. The combination of 8-9 months of annual AC use, extreme attic heat, and Mountain Cedar pollen creates faster accumulation than in milder climates. Homes with pets, recent renovations, or residents with allergies should consider more frequent cleaning. We inspect and advise based on what we actually find, not a calendar. Call (844) 685-6342 to schedule camera inspection and get our recommendation for your specific system.
We can clean fiberglass-lined ducts if the lining is intact and properly adhered. In Leon Valley, we find that’s increasingly rare in original systems. Delaminated fiberglass releases particles into your airstream during cleaning and during normal HVAC operation. We camera-inspect first. If the fiberglass is failing, we recommend removal and replacement with modern materials. We don’t clean ducts in a way that would accelerate fiberglass degradation or create a temporary improvement that masks a structural problem. Call (844) 685-6342 for honest assessment of your original insulation - estimates are free.
