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 San Leon
Air duct cleaning in San Leon typically runs $380-$650 for a full residential system, and most jobs are scheduled within a few days of your call. We’re familiar with the salt-laden bay air and elevated pier-and-beam construction that make San Leon’s ductwork challenges unique among Galveston County communities. Our crews serve San Leon locally, with dispatch and scheduling coordinated from our Dallas-Fort Worth office. If you’re noticing musty odors, reduced airflow, or you’ve recently dealt with high water near Galveston Bay, call us at (469) 972-3151 for a free estimate and camera inspection.
Why Kestrel Air Duct Cleaning Is San Leon’s Preferred Air Duct Cleaning Company
We’ve built our reputation in San Leon by treating bay-front homes differently than inland jobs. The Kingswell Guarantee has governed every visit since 2004: 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 within the guarantee period.
Our technicians are background-checked and uniformed, and they know San Leon’s housing stock. Much of what stands today was rebuilt between 2009 and 2014 after Hurricane Ike, often as elevated pier-and-beam construction to meet post-Ike flood elevation requirements. That matters because the ductwork in these rebuilds is routed through open-air bays beneath the floor decking, exposed to salt air and humidity in ways that inland Galveston County homes simply aren’t.
Calls are answered by a live person, 24/7. Not a voicemail queue. A real conversation, any time of day.
Our Air Duct Cleaning team carries the 365-Day Done Right Promise on every job. If it’s not done right, we make it right, documented in writing.
HVAC Duct Cleaning in San Leon
HVAC Duct Cleaning in San Leon requires a different assessment protocol than standard inland jobs because of the open-air bay exposure common in post-Ike pier-and-beam rebuilds. We start with a video inspection of the main trunk and branch lines, looking specifically for salt corrosion on collars, delamination of duct board, and microbial growth inside flex duct that’s been saturated by bay humidity or past storm surge. Most full residential HVAC duct cleaning jobs in San Leon run between $380 and $650, with commercial systems priced on scope after inspection.
Negative-Air Extraction and Brush Agitation
We use Rotobrush rotary brush systems to dislodge debris at the duct wall, then pull it out with Nikro negative-pressure units. Abatement Technologies HEPA filtration keeps loosened particles out of your living space during cleaning. In San Leon’s humid environment, this matters more than usual because disturbed microbial colonies can re-aerosolize if containment is sloppy.
When Ducts Need Replacement, Not Cleaning
Sometimes we find flex duct or duct board that’s too compromised for cleaning to help. Saturated insulation, torn liners, or corroded metal fittings mean replacement is the only real fix. We document this with before-and-after photos for your insurance file, and we red-tag the damaged runs clearly so there’s no guesswork about what we found.
Vent Cleaning in San Leon
Vent Cleaning in San Leon targets the supply and return registers, grilles, and the short runs of duct immediately behind them where visible dust and debris collect fastest. In bay-front homes, we also find salt crust buildup on register faces and microbial staining on ceiling diffusers from years of humid airflow. A standard vent cleaning for most San Leon homes runs $180-$340 when done as a standalone service, or it’s included in a full system cleaning.
Supply and Return Register Deep Cleaning
We remove each register, clean the face and blade assembly, and vacuum the boot and first few feet of duct behind it. In San Leon’s elevated homes, return registers near floor level often pull in more debris because the negative pressure draws air from the open bay space through any gaps in the subfloor.
Dryer Vent Cleaning
Our dryer vent cleaning service removes lint buildup from the trap housing through the exterior termination. In San Leon’s salt-air environment, metal vent hoods corrode faster, and the lint trap bypass that develops in older installations becomes a genuine fire hazard. We inspect the full run and replace corroded terminations with proper fittings.
Trusted Brands We Service in San Leon
Our technicians arrive with professional-grade equipment: Rotobrush rotary brush systems for mechanical agitation, Nikro negative-pressure units for source extraction, and Abatement Technologies HEPA filtration to protect your indoor air during the job. For homeowners who want to maintain clean air between service visits, we carry Honeywell, Aprilaire, and Guardsman filtration and indoor-air-quality products. We don’t show up with box-store shop vacs and hope for the best. The tools matter, especially in San Leon where salt corrosion and microbial growth demand thorough mechanical cleaning, not surface vacuuming.
Common Air Duct Cleaning Problems We See in San Leon Homes
- Open-air bay duct degradation. Post-Ike pier-and-beam rebuilds route flex duct through completely exposed bays beneath the floor decking. Salt-laden bay air corrodes metal collars and degrades duct board from the outside in, long before reduced airflow alerts the homeowner inside.
- Storm surge saturation. After high water events, under-floor ductwork can hold standing water or saturated insulation. Running the system before inspection spreads moisture and microbial contamination through every supply register in the house.
- False freshness signals. Homeowners sometimes mistake the smell of moving bay air for clean ducts, when the system is actually pulling unfiltered, humid outdoor air through compromised ductwork gaps under the floor.
- Skipped camera inspections. Crews that don’t inspect the open exposed runs miss delaminated duct board and torn flex liners. The air handler keeps ingesting salt air, and the problem returns within a season.
Pricing for Air Duct Cleaning in San Leon, TX
Most full residential HVAC duct cleaning jobs in San Leon run between $380 and $650 for a complete supply-and-return system with video inspection. Standalone vent cleaning typically costs $180-$340. Commercial systems and larger homes with multiple zones are priced on scope after we inspect. What moves the price: the number of supply and return registers, whether the ductwork is accessible or buried in open bays, how much mechanical agitation is needed to dislodge debris, and whether we find damage that requires documentation for insurance rather than simple cleaning. We put the written price in your hands before a single vent is touched. No per-vent add-ons, no door-step revisions, no bait-and-switch. Call (469) 972-3151 for a free estimate.

FAQs About Air Duct Cleaning in San Leon
We run a camera inspection first. If the flex duct or duct board is saturated, delaminated, or the metal collars are corroded through, cleaning won’t restore integrity and we red-tag those runs for replacement. We document everything with before/after photos for your insurance file. Call (469) 972-3151 to schedule an inspection.
Your ductwork lives in essentially outdoor conditions. The open-air bay beneath an elevated pier-and-beam home is bathed in salt-laden Galveston Bay air and humidity year-round, with no conditioned enclosure to protect it. Inland homes in Dickinson or League City typically route ducts through attics or enclosed crawl spaces. That difference in exposure means San Leon ductwork degrades faster and collects more corrosive debris. Most bay-front homes here need inspection every two to three years.
Yes. We photograph every stage, from the initial camera inspection through the cleaning or replacement work, and we provide written findings that note specific damage types: salt corrosion, flood saturation, microbial growth, or structural delamination. Insurance adjusters in Galveston County are familiar with post-storm duct claims, and our documentation is designed to give them what they need to process coverage.
Every two to three years for routine maintenance, and immediately after any storm surge or visible water intrusion under the house. The salt air and humidity here accelerate contamination buildup compared to inland markets, and the open-bay construction means there’s less protection between your ductwork and the bay environment. Call (469) 972-3151 for a free estimate.
Yes, dryer vent cleaning is one of our two confirmed services. It matters here because salt corrosion degrades metal vent hoods and terminations faster than in inland climates, and the lint trap bypass that develops in aging installations becomes a fire hazard in any humid environment where lint clumps rather than flowing freely. We clean the full run and replace corroded fittings.
