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.

AfterFast, Reliable Air Duct Cleaning Across Alamo Heights
Air duct cleaning in Alamo Heights typically runs $380-$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 equipment needed for Alamo Heights’ unique retrofit-era ductwork, not the standard toolkit built for modern suburban homes. Call (469) 972-3151 for a free written estimate before any work begins.
We know Alamo Heights. The narrow streets off Broadway, the brick bungalows tucked behind mature live oaks, the shallow attic chases that hit 150°F in July. Our technicians have cleaned ducts in the 1920s Tudor revivals near Cambridge Elementary and the post-war Colonials along Castano Avenue. That local knowledge matters because Alamo Heights’ housing stock presents problems no generic duct cleaning outfit anticipates. Duct systems here were retrofitted into spaces never designed for them, and a crew that treats your 1940s home like a 2005 subdivision will miss the collapsed flex runs and disconnected joints we’ve learned to expect.
Why Kestrel Air Duct Cleaning Is Alamo Heights’s Preferred Air Duct Cleaning Company
Our reputation in Alamo Heights was built on showing up in the window we promised and leaving the written price unchanged. The Kingswell Guarantee, established when our company was founded in 2004, requires four things on every job: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee with a free return visit if the work fails. No exceptions. We’ve served homeowners from the Monte Vista border to the Olmos Basin edge, and our familiarity with Alamo Heights’ parking constraints, narrow lot lines, and mature tree canopy means we arrive prepared rather than improvising.
Calls are answered by a live person, 24/7. Not a queue, not a callback promise. A real conversation. Our background-checked, uniformed technicians use Rotobrush rotary brush systems for agitation, Nikro negative-pressure units for extraction, and Abatement Technologies HEPA filtration to keep loosened particles out of your living space during cleaning. We document every job with before-and-after photos of your own ducts, not stock images. And our Air Duct Cleaning work is backed by the 365-Day Done Right Promise: if the work falls short within the guarantee period, we return and make it right at no charge, documented in writing on every single job.
Commercial Air Duct Cleaning in Alamo Heights
Commercial Air Duct Cleaning in Alamo Heights addresses the shared HVAC systems and stacked dryer vent configurations common to the area’s multi-unit buildings, professional offices along Broadway, and retail spaces in the Alamo Quarry Market corridor. A typical commercial system cleaning here runs $850-$2,400 depending on square footage, access complexity, and whether video inspection reveals degraded duct board or disconnected flex runs in the ceiling plenum. We schedule around your operating hours and coordinate with building management for shared-system shutdowns.
Multi-Unit and Shared System Expertise
Alamo Heights’ density means many commercial and residential buildings share centralized air handlers or stacked dryer vent runs. Cleaning only the segment visible from a single unit leaves the fire hazard or contamination source intact for the entire stack. We inspect the full run with video equipment, document findings for property managers, and perform source removal on the complete system when authorized.
After-Hours Scheduling and Minimal Disruption
We clean commercial systems during evenings, weekends, or your slow periods. Our crews work with building access protocols, carry proof of insurance and bonding documentation, and leave common areas cleaner than we found them. The Kingswell Way values code governs every visit: say the price, show up in the window, leave the place cleaner, put the guarantee in writing, come back if it fails.
Air Duct Cleaning Services in Alamo Heights
Air Duct Cleaning Services in Alamo Heights encompass residential full-system cleaning, supply and return duct cleaning, video inspection, and dryer vent cleaning for the area’s predominantly pre-1960 housing stock. A typical residential full-system cleaning in Alamo Heights runs $380-$650; dryer vent cleaning adds $150-$280; and video inspection with written findings runs $180-$320. We perform these services with equipment scaled for Alamo Heights’ access constraints, not oversized truck-mount units that require driveway staging impossible on many local streets.
Retrofit-Era Duct Assessment and Cleaning
Most Alamo Heights homes received central HVAC retrofits in the 1960s-1980s, with duct board or early flex duct routed through shallow attic chases and irregular wall cavities. That material is now brittle. Our camera inspection identifies collapsed inner liners and disconnected joints before cleaning begins, so we’re not blowing debris through a system that’s already compromised. We then use brush agitation to dislodge buildup at the duct wall, followed by negative-air extraction to pull contaminants out.
Pollen and Allergen Load Management
San Antonio’s mountain cedar season, peaking December through February, drives some of the highest airborne pollen concentrations in North America. Alamo Heights’ dense live oak canopy adds a second heavy pulse each spring. Older, leakier duct systems pull both straight into the return. Thorough cleaning plus proper filtration, Honeywell and Aprilaire systems available, reduces the allergen reservoir cycling through your home.

Trusted Brands We Service in Alamo Heights
We clean duct systems connected to every major HVAC brand installed in Alamo Heights homes, and we stock filtration products for local pickup or installation. Our technicians carry Honeywell, Aprilaire, and Guardsman filtration and indoor-air-quality products for homeowners who want to maintain clean air between service visits. The Rotobrush systems we use for agitation, the Nikro negative-pressure units for extraction, and the Abatement Technologies HEPA filtration that protects your living space during work are all professional-grade tools, not adapted shop vacs. Parts availability means faster turnaround when a cleaning reveals a component that needs replacement rather than just debris removal.
Common Air Duct Cleaning Problems We See in Alamo Heights Homes
- Collapsed flex duct in shallow attic chases. The 1970s-80s retrofits used flex duct routed through spaces that hit 150°F in summer. The inner liner collapses, restricting airflow and creating a debris trap that standard vacuuming never reaches. Camera inspection finds it; brush agitation and negative-air extraction clear it.
- Disconnected joints dumping conditioned air into the attic. Thermal expansion and brittle sealing materials cause supply and return joints to separate. The system runs longer, costs more, and pulls attic dust into the living space when pressure equalizes. We reconnect and re-seal during cleaning access.
- Shared dryer vent stacks with lint accumulation behind the unit trap. Multi-unit buildings in Alamo Heights often vent through a common stack. Cleaning only the segment from the unit’s lint trap to the wall leaves the leading fire factor in place. We inspect the full stack and perform source removal on the complete run.
- Irregular wall-cavity duct geometry that skips standard cleaning. Retrofit ductwork follows no consistent pattern. A crew with a single hose length and one brush size misses entire branches. We map the system with video, size our tools to the cavity, and clean every accessible segment.

FAQs About Air Duct Cleaning in Alamo Heights
Your Alamo Heights home likely has retrofit ductwork from the 1960s-1980s installed in shallow attic chases that were never designed for HVAC, plus mature live oaks and mountain cedar loading the system with pollen that leaks in through degraded joints. Newer suburbs have purpose-built duct systems with better sealing and less allergen exposure. Call (469) 972-3151 for a free inspection and written estimate.
Yes. We use portable Nikro negative-pressure units and Rotobrush systems that our technicians carry to the door, not oversized truck-mount equipment that requires driveway staging. We coordinate parking and access before arrival so the job isn’t rushed. Call (469) 972-3151 to discuss your specific access situation.
We inspect the full stack with video equipment from accessible points, document findings for the property manager or HOA, and perform source removal on the complete shared run when authorized. Cleaning only the segment from your unit’s lint trap to the wall leaves the fire hazard in place for the entire building. Call (469) 972-3151 to schedule a stack inspection.
Collapsed inner liners in flex duct, disconnected joints at seams and takeoffs, and brittle duct board that crumbles under aggressive cleaning. We find these with camera inspection before touching the system, then adjust our brush agitation pressure and tool selection to clean thoroughly without causing additional damage. Call (469) 972-3151 for a video inspection of your system.
Yes. San Antonio’s mountain cedar season produces some of the highest airborne pollen concentrations in North America, and Alamo Heights’ dense live oak canopy adds a significant spring pulse. Older, leakier duct systems pull that pollen straight into the return, where it accumulates and recirculates. Thorough cleaning reduces that reservoir, and Honeywell or Aprilaire filtration maintains the improvement. Call (469) 972-3151 for a system assessment and filtration options.
