That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Air Duct Cleaning Across Leon Valley
Air duct cleaning in Leon Valley typically runs $350-$650 for a full residential system, with most jobs completed in a single visit. We dispatch crews from our San Antonio office and carry the tools to handle the specific problems this city’s older housing stock throws at us. Call (469) 972-3151 for a free written estimate before any work begins.
We’ve been driving the corridors of Leon Valley long enough to know which ranch homes off Huebner Road still run original fiberglass duct board from the 1960s, and which post-retrofit systems on Evers Road are hiding crushed returns above low-clearance attic spaces. That local knowledge changes what we bring to the job and what we find when we get there. Leon Valley isn’t a generic suburb, and its ductwork doesn’t behave like one either.
Why Kestrel Air Duct Cleaning Is Leon Valley’s Preferred Air Duct Cleaning Company
Our reputation here was built on showing up in the window we promised and leaving the written price alone after we arrive. The Kingswell Guarantee, which governs every Kestrel job, requires four things: a written price before work starts, a defined arrival window, a clean job site, and a written guarantee with a free return visit if the work fails within the guarantee period. We’ve applied that standard since 2004.
Leon Valley homeowners call us back because we answer the phone with a live person, 24/7, and because our technicians are background-checked, uniformed, and trained on professional-grade equipment rather than box-store shop vacs. We use Rotobrush rotary brush systems to dislodge debris at the duct wall, Nikro negative-pressure units to pull contaminants out, and Abatement Technologies HEPA filtration to keep loosened particles out of the living space during cleaning. We don’t just clean ducts. We document what we find, explain it in plain language, and put our 365-Day Done Right Promise in writing on every single job.
Ductwork Cleaning in Leon Valley
Ductwork Cleaning in Leon Valley means something different than it does in a 2019 subdivision up in the Hill Country. Most of this city was built between 1950 and 1970 for Kelly Air Force Base workers and military families, and much of it was originally designed for window units or gravity furnaces, then retrofitted with central AC. That retrofit history, not just age, is why we find crushed or disconnected runs here far more often than in newer suburbs a few miles north. The ductwork is a patchwork of original fiberglass duct board and undersized sheet-metal runs rather than a single designed system.
Our process starts with negative-air extraction, which means we hook a powerful vacuum to your main trunk line to create suction throughout the system. Then we use brush agitation, sending rotary brushes through each supply and return run to knock loose the accumulated debris that vacuum suction alone won’t touch. For Leon Valley’s older systems, we often find that cleaning reveals the real problem: delaminating duct board, disconnected boots, or crushed flex runs that have been pulling attic air into the supply side for years.
A typical Ductwork Cleaning in Leon Valley runs $350-$550 for a standard ranch home with one system. Homes with multiple HVAC zones, extensive duct board replacement needs, or hard-to-access attic runs may run higher. We give you the exact number in writing before we start.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, but in Leon Valley’s retrofit systems they’re often the same original fiberglass channels installed when the house ran on a gravity furnace. We clean these with rotary brush agitation followed by negative-air extraction, then inspect for delamination or crushed sections that are dumping cooled air into your attic instead of your living room.
Return Duct Cleaning
Return ducts pull air back to the air handler, and in Leon Valley’s 1960s ranches they’re frequently undersized for the central-AC load added decades after construction. We clean the full return pathway and check for leaks at the air handler plenum, where retrofit connections often fail and pull unfiltered attic air, cedar pollen, and dust directly into your system.
Air Duct Inspection in Leon Valley
Air Duct Inspection in Leon Valley is often the step that prevents a wasted cleaning. On a 1968 ranch off Evers Road, our tech pulled a supply register and found the original fiberglass duct board delaminating, shedding fibers into the airstream, with a return run that had been crushed flat during a later central-AC retrofit. We ran camera inspection through the supply and return ducts, did source removal with agitation tools under negative pressure and HEPA filtration, then sealed and reconnected the crushed run at the air handler. The homeowner’s complaint, dust settling on furniture within a day of cleaning, stopped, and the blower motor stopped short-cycling against the leaky duct.
That story repeats across Leon Valley. Original 1960s-70s fiberglass duct board in these ranch homes delaminates after 50-plus years of South Texas humidity cycling, shedding fibers directly into the airstream instead of just trapping dust. Post-retrofit ductwork from window-unit conversions is often undersized or poorly sealed, so a standard cleaning passes NADCA lint-pathway checks but the system still leaks and short-cycles the air handler. Crushed or disconnected runs hidden above ceiling drywall in low-clearance ranch attics pull attic air and cedar pollen into the supply side, undoing any cleaning within a season.
A camera inspection lets us see these problems before we quote the work. Air Duct Inspection in Leon Valley typically runs $150-$250 as a standalone service, or it’s included when bundled with a full cleaning. We show you the footage. No interpretation needed.
Video Inspection
We feed a high-resolution camera through your supply and return runs to document delamination, disconnected boots, crushed flex, or biological growth. You see what we see. In Leon Valley’s older homes, this step often reveals why previous cleanings didn’t solve the dust problem.
System Assessment
After inspection, we assess whether cleaning alone will solve your issue or if sealing, repair, or partial replacement is needed. We put that assessment in writing with line-item pricing before any work begins. No door-step revisions.
Trusted Brands We Service in Leon Valley
Our technicians arrive with Rotobrush rotary brush systems, Nikro negative-pressure extraction units, and Abatement Technologies HEPA filtration equipment on every Leon Valley job. These aren’t shop vacs with extra hoses. The Rotobrush scrubs debris loose from duct walls. The Nikro pulls it out under controlled suction. The Abatement Technologies HEPA system traps particles down to 0.3 microns so they don’t resettle in your home during the process. For homeowners who want to maintain clean air between service visits, we also carry Honeywell, Aprilaire, and Guardsman filtration and indoor-air-quality products. We stock common parts and materials locally, so when an inspection reveals a disconnected boot or failed seal, we can often address it same visit rather than scheduling a return trip.
Common Air Duct Cleaning Problems We See in Leon Valley Homes
- Delaminating fiberglass duct board. Original 1960s-70s duct board in Leon Valley ranch homes sheds fiberglass fibers into the airstream after decades of humidity cycling. Cleaning without inspection misses this entirely, and standard brush agitation can accelerate the damage if the board is already failing.
- Crushed or disconnected retrofit runs. Central AC was added to many Leon Valley homes years after construction, often by contractors who squeezed ducts through spaces never designed for them. We find flattened flex runs and disconnected boots hidden above drywall that pull attic air straight into your supply side.
- Undersized returns causing short cycling. Gravity-furnace conversions frequently left return pathways too narrow for modern AC loads. The blower motor strains, energy bills climb, and the system never achieves proper airflow even after a thorough cleaning.
- Year-round biological loading from mountain cedar and cooling-season mold. Leon Valley’s AC runs April through October, and the San Antonio metro’s Ashe juniper pollen season peaks December through February. Ducts in these older homes, with their compromised seals and degraded liners, accumulate particulate and biological material continuously.
Pricing for Air Duct Cleaning in Leon Valley, TX
Most full-system air duct cleaning jobs in Leon Valley run between $350 and $650. A single-zone ranch with straightforward access typically falls at the lower end. Homes with multiple HVAC systems, extensive duct board damage requiring repair, or hard-to-access attic runs push toward the higher end. Camera inspection, when needed, adds $150-$250.
We don’t quote per-vent pricing. We don’t offer teaser coupon rates that balloon once the van is in your driveway. We give one flat price per system, agreed in writing before any vent is touched. That price covers the full cleaning, HEPA-contained extraction, and our 365-Day Done Right Promise. If the work falls short within that year, we return and make it right at no charge. The guarantee is documented on every job, not a verbal assurance that disappears with the technician.
Call (469) 972-3151 for a free estimate. We’ll ask about your home’s age, system configuration, and any symptoms you’ve noticed, then give you a written range before we schedule.

FAQs About Air Duct Cleaning in Leon Valley
Because Leon Valley’s 1950s-1970s ranch homes frequently hide crushed retrofit runs and delaminating fiberglass duct board that a standard cleaning will miss or worsen. The camera shows us whether the duct structure can tolerate brush agitation or needs repair first. Call (469) 972-3151 to schedule an inspection with your cleaning.
It depends on the condition of the board, which we determine by camera inspection. If the fiberglass is intact and properly sealed, source removal cleaning under negative pressure with controlled brush agitation is effective. If the board is delaminating and shedding fibers, partial or full replacement is the safer long-term solution. We show you the camera footage and give you both options in writing.
Yes. The San Antonio metro’s Ashe juniper pollen season, running December through February, is one of the most intense in the country. In Leon Valley’s older homes with compromised duct seals, that pollen pulls directly into the system and accumulates in duct board liners and crushed runs. Combined with a cooling season that stretches from April through October, the biological loading here is heavier than in climates with shorter pollen and AC seasons.
Source removal means we physically dislodge and extract debris from the duct walls rather than just vacuuming loose dust. On Leon Valley’s retrofit systems, we use Rotobrush agitation to knock material loose from original fiberglass duct board and sheet-metal runs, then extract it with Nikro negative-air units under Abatement Technologies HEPA containment. The “source” is the accumulated debris in your specific duct geometry, not a generic cleaning template.
Cleaning helps, but sealing is often the real fix in Leon Valley’s retrofit systems. When crushed runs, disconnected boots, or failed plenum seals pull attic air into the supply side, new dust enters within days of any cleaning. Our camera inspection identifies these leaks, and we quote sealing or reconnection work alongside the cleaning when needed. The 365-Day Done Right Promise covers both.
