We’ve been driving to Leon Valley since 1984, back when Bandera Road was the main corridor and most of these homes were already twenty years old. The city hasn’t changed much in footprint, it’s still that same landlocked enclave surrounded by San Antonio, but what sits inside those attics has aged hard. We’re familiar with the original ranch homes on the streets near John Marshall High School, the 1960s subdivisions off Evers Road, and the mid-70s builds closer to Huebner Road. Each has a different duct configuration, and each has a different story of what forty-plus years of San Antonio heat and cedar pollen have left behind. Call (866) 347-2063 for a free estimate, we’ll give you an honest price before we start, and we’ll show you exactly what your ducts look like on camera before we touch them.
Why Bellows Air Duct & Vent Co. of Texas Is Leon Valley’s Preferred Air Duct Cleaning Company
Our reputation in Leon Valley was built one house at a time, mostly by homeowners who called after a bad experience with a low-bid coupon service that vacuumed for twenty minutes and left. They found us because a neighbor recommended the company that shows the video. Wade Kellerman has run Bellows since its founding, and the 90-Day Done Right Promise he put in writing decades ago still governs every job we send to Leon Valley: if it’s not right, we return at no charge, no paperwork, no arguing.
Leon Valley customers specifically mention our camera inspections in reviews. They like that we don’t claim the ducts are dirty, we prove it, and we prove they’re clean after. Our response time to Leon Valley is typically same-day or next-day, because our trucks stay stocked and our dispatchers answer the phone live, not through an app or voicemail tree. We know which streets have the original 1960s galvanized trunk lines, which developments used early flex duct that failed first, and which homes sit where caliche dust blows heaviest off the lots near Bandera Road. That local knowledge means we bring the right equipment the first time, and we don’t waste your morning figuring out what we’re looking at.
Our Air Duct Cleaning Services in Leon Valley
Residential Duct Cleaning
Leon Valley’s housing stock is almost entirely single-story, slab-on-grade ranch homes built between 1960 and 1985, with attic-mounted duct runs that have never been replaced in many cases. Our residential cleaning targets the full supply and return network, using Rotobrush contact cleaning and Nikro HEPA vacuum systems to extract decades of accumulated debris. On the older streets just off Bandera Road, we pulled duct-access panels to find original 1960s galvanized trunk lines layered with caliche dust and cedar pollen, plus deteriorating flex-duct branch lines that had never been replaced. Using our Rotobrush system and Abatement Technologies HEPA filtration, we extracted decades of debris, reducing the homeowner’s cedar fever symptoms significantly. Most Leon Valley residential jobs run $280-$450 and finish in one visit.

Commercial Duct Cleaning
Leon Valley’s commercial base is smaller than San Antonio’s, but the retail strips along Bandera Road and the office buildings near the city center have their own duct histories. Many converted from residential or light commercial use, inheriting undersized or aging systems. We clean these with the same camera-verified approach, scheduling around business hours to avoid disruption. Commercial pricing in Leon Valley starts around $400 for smaller systems and scales with square footage and access complexity.

Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, and in Leon Valley they face a specific problem: 130°F-plus attic temperatures for eight to nine months a year degrade flex-duct insulation and crack inner liners, dropping fiberglass particles and attic debris directly into your airflow. We clean supply trunk lines and branch ducts with contact agitation and negative-air HEPA collection, then video-verify the results. Supply-only cleaning in Leon Valley runs $180-$320.

Return Duct Cleaning
Return ducts pull air back to your HVAC system, and in Leon Valley they act as the primary intake for what makes this area unique. The Ashe juniper corridor that surrounds the city floods outdoor air with microscopic pollen particles from December through February, and your return system is the entry point. We clean return plenums, filter racks, and trunk lines, removing the pollen residue that triggers cedar fever symptoms. Return-only cleaning in Leon Valley typically costs $160-$290.

Full System Cleaning
This is what most Leon Valley homes need. Full system cleaning covers supply and return ductwork, the air handler cabinet, blower assembly, and coil if accessible, plus before-and-after video inspection of key access points. For original 1960s-80s systems, this is often the first comprehensive cleaning ever performed. Full system cleaning in Leon Valley runs $350-$550, with most homes falling in the $380-$450 range.

Video Inspection
Every Bellows job in Leon Valley includes video inspection before and after work begins. For homes with original galvanized trunk lines, this isn’t optional, it’s how we document condition without tearing into walls. Our cameras navigate the tight turns of aging duct systems and record findings you can see on screen. Standalone video inspection for diagnostic purposes costs $120-$180 in Leon Valley.

Trusted Brands We Service in Leon Valley
We clean ductwork connected to all major HVAC brands, and we stock common replacement components for systems we see frequently in Leon Valley’s older homes. That includes Honeywell media filters and electronic air cleaners, Aprilaire whole-house humidifiers and ventilation controls, and Guardsman register boots and access panels. For the cleaning itself, we run professional-grade Rotobrush contact systems and Nikro HEPA vacuum equipment, the same tools serious HVAC contractors specify. Keeping parts on the truck means we don’t leave Leon Valley to chase a fitting across San Antonio. Most repairs that surface during cleaning, cracked flex duct, failed boots, loose trunk line seams, we can fix same-day because we brought what the job requires.
Common Air Duct Cleaning Problems We See in Leon Valley Homes
- Aging original flex duct from the 1960s-80s degrades in 130°F+ attic heat. The inner liners sag and crack, dropping fiberglass particles and attic debris directly into the airstream. We find this on almost every pre-1985 home in Leon Valley, and it’s worse on streets with darker shingle roofs that absorb more heat.
- Cedar pollen (Ashe juniper) infiltrates return-air systems December through February. Leon Valley sits in the epicenter of North America’s worst Mountain Cedar pollen belt, and the microscopic particles coat duct interiors, triggering severe allergic reactions. We’ve cleaned return plenums in January that were visibly gray with pollen residue.
- Caliche dust from the soil accumulates in galvanized trunk lines and is never cleaned out. This alkaline, chalky soil byproduct mixes with biofilm and pollen to form heavy residue that standard vacuums won’t touch. It’s unique to this region’s geology, and technicians from outside Bexar County often don’t recognize what they’re seeing.
- Original sheet-metal trunk lines have never been sealed or inspected. Forty years of thermal expansion and contraction have loosened joints and separated seams, pulling unconditioned attic air into the system and reducing efficiency. Our camera inspection finds these leaks before we clean, so we can address them rather than blow debris through new gaps.

FAQs - Air Duct Cleaning in Leon Valley
Original duct systems in Leon Valley’s 1960s-85 housing stock have endured 40-plus years of 130°F attic heat without replacement, degrading flex-duct liners and accumulating caliche dust and cedar pollen that newer flex-duct materials and tighter construction simply don’t experience. The combination of extreme thermal aging and unique regional allergen loads makes these systems measurably dirtier than even homes built a few miles northwest in the 1990s and 2000s. We typically recommend cleaning every 3-5 years for these older systems, versus 5-7 for newer construction. Call (866) 347-2063 to schedule your video inspection.
Yes, removing cedar pollen residue from return-air ducts and plenums reduces the allergen load circulating through your home during the December-February peak. We’ve had Leon Valley customers report significant reduction in symptoms after full system cleaning, particularly when combined with upgraded filtration. The pollen is microscopic and lodges in duct interiors where standard filters can’t reach. Call (866) 347-2063 for a free estimate before next cedar season.
Caliche is a calcium-carbonate-rich soil layer common to South Texas geology; when disturbed by construction, wind, or landscaping, the fine alkaline dust becomes airborne and enters attic vents and duct systems. In Leon Valley, it mixes with pollen and biofilm to form a distinctive heavy, chalky residue that coats original galvanized trunk lines. It’s not household dust, it’s regional geology, and it requires professional contact agitation to remove. We see it on nearly every pre-1985 home we clean in the city. Call (866) 347-2063 to see what your ducts contain.
We use controlled-contact Rotobrush systems with soft polymer whips rather than aggressive mechanical tools, paired with variable-suction HEPA vacuum to extract debris without stressing aged metal seams. Our technicians are trained to identify where galvanizing has thinned and where seams have separated, adjusting technique to avoid enlarging existing damage. Video inspection before and after documents condition and verifies we haven’t caused harm. This careful approach takes longer than a quick vacuum job, but it’s the only responsible way to handle forty-year-old metal. Call (866) 347-2063 to discuss your system’s condition.
We include it on every job because original duct systems hide problems that aren’t visible from registers: separated flex-duct connections, corroded trunk line seams, and accumulated debris pockets that would otherwise go unaddressed. For Leon Valley’s 1960s-80s housing stock, the video record protects you and us, it proves what was there and what we accomplished. Standalone inspection is available if you’re not ready to commit to full cleaning. Call (866) 347-2063 to schedule.
