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.

Air Duct Cleaning Services in San Leon
Air Duct Cleaning Services in San Leon address a problem most Gulf Coast homeowners don’t realize they have until the musty smell won’t go away or the cooling bill climbs every summer. Our process starts with a video inspection using Nikro camera systems to see inside your duct runs, especially the flex lines beneath pier-and-beam floors where salt air and humidity do their worst work. We then use Rotobrush mechanical agitation combined with negative-pressure extraction to source-remove debris, biofilm, and corrosion particulates, not just push them around. A typical residential air duct cleaning in San Leon runs $350-$550 for a single-system home, $500-$650 for larger or multi-zone systems, and $800-$1,400 for commercial properties depending on square footage and access complexity.
Residential Duct Cleaning
We clean supply ducts, return ducts, and the full trunk line from the air handler through every register, protecting your floors and furniture with drop cloths throughout. Homes with kids and pets get extra attention to vent covers and surrounding areas.
Commercial Duct Cleaning
Restaurants, retail, and office spaces in San Leon face the same bay-driven humidity challenges as residences, often with more complex rooftop or multi-floor systems. We schedule around your business hours and provide the same written upfront pricing.

HVAC Duct Cleaning in San Leon
HVAC Duct Cleaning in San Leon is not the same service you’d get in Houston or Dallas. Galveston Bay’s persistent onshore winds carry salt particulates that corrode flexible duct liners and metal fittings from the outside in, while interior surfaces accumulate moisture-driven biofilm year-round. Our HVAC duct cleaning addresses both problems: mechanical agitation to remove interior buildup, plus inspection of exterior-facing flex runs for salt degradation and structural failure. A typical HVAC duct cleaning in San Leon runs $400-$600 for standard residential systems, with post-inspection repairs or re-connections quoted separately in writing before any additional work.
Video Inspection and Assessment
Every HVAC duct cleaning starts with a camera run through your system. We show you what we find, explain what it means for your air quality and energy costs, and build the cleaning scope from actual conditions, not assumptions.
Full System Cleaning and Sealing
We clean the air handler, coils, and blower assembly in addition to duct runs, then seal accessible joints with mastic where degradation has created leaks. This is especially critical in San Leon’s elevated homes, where negative pressure can pull raw bay air through gaps you cannot see.
Trusted Brands We Service in San Leon
Our crews arrive with professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, not rental-shop vacuums with brush attachments. We’ve chosen these brands because they hold up to the demands of San Leon’s salt-air environment: Nikro’s camera systems let us inspect flex runs in tight, humid under-floor spaces without adding moisture, and Rotobrush’s mechanical agitation breaks biofilm loose from duct liners so negative pressure can extract it completely. We stock common fittings and repair materials for post-Ike duct systems, which means when we find a disconnected collar or corroded boot under your floor, we can often fix it same visit rather than scheduling a return trip.
Common Air Duct Cleaning Problems We See in San Leon Homes
- Under-floor flex disconnects in pier-and-beam foundations. FEMA flood-zone rules pushed most post-Ike ductwork into open, unsealed under-floor spaces, so flex runs sag, kink, or pull free from register boots, silently drawing raw salt-humid bay air into your supply stream for years.
- Salt-driven corrosion of duct liners and metal fittings. San Leon’s near-constant marine air exposure degrades flex duct from the outside in at rates far exceeding inland Galveston County, meaning 2009-2012 installations are now at genuine failure threshold.
- Idle-season mold establishment in part-time properties. HVAC systems that sit unused for weeks in extreme coastal humidity become prime environments for mold and mildew to establish deep in ductwork before any occupant notices the smell.
- Flood-contaminated duct systems from past hurricane events. Hurricane Ike inundated much of San Leon, and residual debris or biological matter in under-floor duct runs often survives standard seasonal maintenance until a thorough inspection reveals it.

FAQs About Air Duct Cleaning in San Leon
San Leon’s position directly on Galveston Bay exposes every home to the highest ambient humidity on the entire Texas Gulf Coast, plus salt-laden marine air that keeps duct surfaces perpetually moist. Inland communities just miles away see significantly lower corrosion and biofilm rates. Call (323) 918-4345 for a free inspection if you smell mustiness or see unexplained cooling-cost increases.
No. Fogging sanitiser is a masking agent that does not remove biofilm from duct surfaces, and in San Leon’s humidity, it can actually add moisture that encourages faster regrowth. Our mechanical agitation and negative-pressure extraction source-removes contamination instead of covering it. Save your money; the clean itself is what matters.
Post-Ike rebuilds elevated on pier-and-beam or stilt foundations leave flex duct runs exposed to raw bay air in unsealed under-floor spaces, creating double exposure to salt and humidity from below as well as inside. Our crews inspect these runs with cameras, re-secure disconnected collars, and seal gaps that standard cleaning ignores. This is unique to San Leon’s flood-zone building requirements and is not a factor in slab-on-grade inland homes.
Yes, and possibly more urgently. HVAC systems that sit idle for weeks in Galveston Bay humidity allow mold to establish deep in ductwork before any occupant arrives to notice it. We recommend pre-season inspection and cleaning before you reopen the property, not after you smell the problem. Call (323) 918-4345 to schedule before your next visit.
A real clean includes video inspection, mechanical agitation with professional equipment like Rotobrush systems, negative-pressure extraction, and physical inspection of under-floor flex runs for disconnects, sags, or salt corrosion. Cheap specials typically vacuum only accessible supply and return ducts, skip the camera, ignore under-floor damage, and upsell fogging sanitiser to mask what they missed. Ask any competitor: will they pull your under-floor flex loose to inspect it? Most won’t.
Our techs recently worked a post-Ike stilt home on the bayside streets near the San Leon Municipal Park, where a 2009-era flex trunk had pulled free from its register boot under the floor decking, silently drawing salt-humid bay air into the supply stream. We set up negative pressure at the air handler, ran a camera inspection through the under-floor run, re-secured the loose collar, and source-removed a heavy biofilm layer before sealing the boot. The homeowner’s chronic musty odor and the summer cooling-cost creep both cleared after the reconnect and clean.
