Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
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.

We’re the Air Duct Cleaning team that serves rural properties around San Antonio with the same written price guarantee we bring to every job in Pasco County.
Our dispatch office in Miami coordinates scheduling for San Antonio, and our technicians make the drive up US-98 or I-75 with Rotobrush and Nikro equipment in the van. We know the long ranch drives off County Road 772, the dust that lifts off unpaved roads after a dry spell, and the way cedar fever season hits harder out here where the Ashe juniper grows thick on the Hills of San Antonio ridgeline. If your home sits on a well and septic with a shop or barn on its own mini-split, we’ve cleaned systems like yours before. Call (469) 972-3151 and a live person will pick up, day or night.
Why Kestrel Air Duct Cleaning Is San Antonio’s Preferred Air Duct Cleaning Company
We’ve been working under the Kingswell Guarantee since 2004, and that means four things on every San Antonio visit: a written price before we touch a vent, a defined arrival window, a clean job site when we leave, and a written 365-Day Done Right Promise with a free return visit if anything fails.
San Antonio homeowners call us after they’ve dealt with the opposite. A technician who showed up three hours late. A quote that doubled once the brushes were running. A shop vac with a Home Depot sticker where professional equipment should’ve been. Our technicians are background-checked, uniformed, and trained on Rotobrush rotary brush systems, Nikro negative-pressure units, and Abatement Technologies HEPA filtration. We explain what each tool does before we start.
The Kingswell Way governs every visit to San Antonio. Say the price. Show up in the window. Leave the place cleaner. Put the guarantee in writing. Come back if it fails. Dale Whitmore built this standard into the company from the start, and it hasn’t changed.
HVAC Duct Cleaning in San Antonio
HVAC Duct Cleaning in San Antonio means source removal from the entire forced-air system: supply trunks, return trunks, branch lines, and the air handler cabinet. For rural San Antonio homes on unpaved ranch roads, this isn’t a cosmetic service. The fine alkaline dust from gravel drives and cleared pasture lime loads flex-duct liner with abrasive particulate that accelerates degradation, especially in attic systems that bake at 140-160°F through nine months of cooling season.
Most full HVAC duct cleaning jobs in San Antonio run $450-$850 depending on system size, accessibility, and whether we find crushed or disconnected flex sections that need replacement. We inspect with a camera first, show you what we’re seeing, and put the full price in writing before the Rotobrush starts turning.
Negative-Air Extraction and Brush Agitation
Our Nikro negative-air machine hooks to your trunk line and pulls continuous suction while the Rotobrush scrubs the duct walls. Think of it as a dental cleaning for your ducts: the brush loosens the buildup, the vacuum captures it before it escapes into your living space, and the Abatement Technologies HEPA filter traps particles down to 0.3 microns. We run this on every San Antonio job, rural or urban.
System Inspection and Repair Integration
Camera inspection often reveals what brush cleaning alone would miss. Crushed flex behind stored items in a detached shop. Disconnected collars where Vertisol clay soil shifted the foundation. Oily creosote film from wood-stove returns that traps dust in a layer standard brushing won’t touch. We document everything, quote repairs in the same written estimate, and handle them during the same visit when possible.
Vent Cleaning in San Antonio
Vent Cleaning in San Antonio targets the visible and immediate: supply and return registers, grille faces, and the first few feet of ductwork behind them. For rural San Antonio properties, this is often where cedar pollen and ranch-road dust first announce themselves. You’ll see gray film on the grille louvers, or a filter that blinds inside six weeks instead of three months.
Standalone vent cleaning runs $150-$300 in San Antonio, though most homeowners pair it with full system work for better value. If you’re sneezing through cedar fever season and the return grilles look like they’ve been dusted with pale yellow chalk, start here. We’ll show you the before-and-after with our camera.
Register Deep-Cleaning and Sealing
We remove each grille, clean the face and blades, and vacuum the boot behind it. Then we check the seal between boot and drywall. Gaps here are common in San Antonio’s 1970s-1990s tract homes, and they pull attic air straight into your supply stream. No brush system fixes a leaky boot; we seal it with proper mastic or replace the collar if it’s degraded from attic heat.
Filter Assessment and MERV Matching
Rural San Antonio homes need filters matched to actual loading, not just the slot size. A filter too dense for your blower motor restricts airflow and strains the system. Too porous, and cedar pollen recirculates all winter. We stock Honeywell and Aprilaire media and can recommend a Guardsman upgrade if your allergy load justifies it.
Trusted Brands We Service in San Antonio
We clean ductwork connected to every major HVAC brand, and we stock Honeywell media filters, Aprilaire whole-house air cleaners, and Guardsman filtration products for San Antonio homeowners who want to maintain clean air between service visits. Our vans carry common flex-duct sizes, collar fittings, and mastic supplies so most repairs don’t wait on a parts run. If your system uses proprietary components, we’ll tell you before we start and source what we need without marking up the turnaround.
Common Air Duct Cleaning Problems We See in San Antonio Homes
- Alkaline ranch-road dust caking flex-duct liner. The fine powder from unpaved drives near County Road 772 and the Hills of San Antonio behaves like a mild abrasive. It polishes the interior of flex ducts and loads filter media months faster than urban caliche dust. Homeowners often don’t notice until static pressure spikes and rooms stop cooling evenly.
- Creosote film from wood heat trapping debris. Rural San Antonio properties that run wood stoves or fireplaces through winter push smoke with oily particulate through return ducts. Standard brush cleaning skims the surface; we use solvent-compatible agitation tools and inspect with a camera to verify the film is gone.
- Crushed or overheated flex in detached shops and barns. Outbuilding systems on rural properties get deferred for years. Their supply ducts run through attics that hit 160°F in August, degrading the liner. Saddle racks, hay bales, or stored equipment often crush flex runs against rafters. We replace what we can’t restore.
- Cedar pollen infiltration during mountain cedar season. From December through February, Ashe juniper pollen blankets rural San Antonio with particles fine enough to pass standard filters. Without proper MERV-rated media, that pollen recirculates through supply and return ducts and compounds allergy loads for months after the trees stop releasing.
Pricing for Air Duct Cleaning in San Antonio, FL
Most residential air duct cleaning in San Antonio falls between $350 and $650 for a full system, with larger rural homes or properties with detached shop systems running $650-$950. Vent cleaning alone starts at $150. Commercial ductwork is priced by linear foot and access difficulty; call for a custom quote.
What moves the number: system size, number of supply and return branches, attic accessibility, whether we find disconnected or crushed duct that needs repair, and how long it’s been since the last cleaning. A rural San Antonio home on five acres of unpaved road with a shop mini-split and fifteen years of deferred maintenance is a different job than a three-year-old tract home in Wesley Chapel.
We give one flat price per system, agreed in writing, before a single vent is touched. No per-vent add-ons. No dispatch fees that appear after we arrive. No door-step revisions. You’ll see before-and-after photos of your own ducts, and if anything in our written scope falls short within 365 days, we return and make it right at no charge. Call (469) 972-3151 for a free estimate.

FAQs About Air Duct Cleaning in San Antonio
Every two to three years for rural San Antonio properties on unpaved roads, not the generic five-year interval you’ll see online. The alkaline dust from ranch roads and pasture lime loads ducts faster than urban particulate, and the combination with cedar pollen and wood-heat residue creates layered buildup that brush-only maintenance won’t address. Call (469) 972-3151 and we’ll inspect with a camera to tell you where your system stands.
Yes, significantly. From December through February, mountain cedar (Ashe juniper) releases pollen particles fine enough to pass standard fiberglass filters and lodge in ductwork, where they recirculate for months. We find yellow-gray accumulation in return trunks every spring, and homeowners report reduced allergy symptoms after proper source removal with HEPA-contained cleaning. Upgrading to a Honeywell or Aprilaire MERV 11-13 filter helps between cleanings.
HVAC duct cleaning covers the full forced-air system: supply trunks, return trunks, branch lines, and the air handler. Vent cleaning addresses only the registers, grilles, and the short boot sections behind them. If your grilles are filthy but rooms heat and cool evenly, vent cleaning may suffice. If you’ve got uneven airflow, rising energy bills, or it’s been years since full service, you need the complete job. We price both separately and together.
Yes. We’ve cleaned mini-split duct runs, supplemental heat-pump systems, and outbuilding flex lines on properties from the Hills of San Antonio to the Brooksville border. These systems often run through unconditioned attics that destroy flex liner, and they’re frequently crushed by stored equipment. We inspect with a camera, replace degraded sections, and include the outbuilding in your written price if you want it serviced during the same visit.
Rural San Antonio properties face loading factors that urban and suburban homes don’t: unpaved road dust that’s finer and more alkaline than city caliche, wood-heat particulate that creates sticky trapping films, longer service drives that lead homeowners to defer maintenance, and outbuilding systems that overheat in attic spaces. Even two miles apart, a home on a paved subdivision road and a ranch on County Road 772 are operating in different environments. Your cleaning interval should reflect your actual conditions, not a national average.
