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.

AfterAir Duct Cleaning Company in San Leon, TX
Air duct cleaning in San Leon runs $280 – $520 for a typical single-system home, with most jobs falling between $320 and $400. We’re Hollis Air Duct Cleaning, and we’ve learned that San Leon work isn’t really about dust removal, it’s about fighting what the Gulf does to ductwork. The salt-laden, humid air here leaves a corrosive film inside ducts that inland crews never see. Call us at (361) 326-5060 for a free written estimate.
Why San Leon Homes Are Different
San Leon sits on Galveston Bay’s edge, and that position changes everything about our work. The housing stock is mostly older elevated cottages, fishing cabins, and post-Hurricane Ike rebuilds on pilings, plus small 1950s – 1970s bungalows and newer stilt homes. Many still run original or minimally upgraded ductwork, flexible insulated ducts tucked into crawlspaces or attics where moisture and salt get trapped and stay.
After a storm surge or even a heavy bay wind, we pull off return registers and find a fine gray salt film coating the inside, blower wheels included. That salt accelerates corrosion of metal ducts, registers, and HVAC components while the constant humidity promotes mold and mildew growth. Post-storm repairs often leave gaps that pull unfiltered outside air straight into the system. Inland suburbs like League City or Pasadena don’t deal with this. We do.
Our Main San Leon Services
San Leon homeowners call us for three jobs, each handled with The Garrison Standard: written price first, background-checked uniformed technicians, and our 365-Day Done Right Promise on every visit.
Air Duct Cleaning in San Leon
We use a Rotobrush rotary brush system combined with negative-air extraction to remove the salt film, microbial growth, and accumulated debris that Gulf humidity deposits inside San Leon ductwork. Every supply and return vent gets brushed and vacuumed, then we inspect with a camera so you see the before and after. The goal isn’t just cleaner air, it’s stopping the corrosion that shortens HVAC life in coastal conditions. Air Duct Cleaning in San Leon
Dryer Vent Cleaning in San Leon
Salt air corrodes dryer vent hoods and lint traps faster here, and the humidity makes lint clump and stick instead of blowing through cleanly. We run a rotary brush through the full vent line to the exterior hood, check airflow with a meter, and verify the termination cap operates freely. For homes on pilings or with longer vent runs, we inspect for sagging lines where lint collects. Dryer Vent Cleaning in San Leon
Duct Sealing in San Leon
Post-storm repairs and decades of coastal vibration leave San Leon duct systems leaking conditioned air into attics, crawlspaces, and wall cavities. We apply duct sealing mastic and reinforced tape at joints and seams, then pressure-test to verify results. Sealing first means your cleaned ducts stay clean longer, and your HVAC doesn’t pull humid, salty outside air through gaps. Duct Sealing in San Leon
