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 Leon Valley, TX
Hollis Air Duct Cleaning handles ductwork, dryer vents, and sealing throughout Leon Valley, where the Balcones Escarpment transition zone creates unique indoor air challenges. Most homes here run HVAC year-round through humid summers and mild winters, pulling pollen, limestone dust, and mold spores through duct systems that have never been professionally cleaned. We’re part of the Garrison Partners family, and every Leon Valley job starts with a written price that doesn’t move, backed by our 365-Day Done Right Promise. Call (361) 326-5060 to schedule a free estimate.
Why Leon Valley Homes Are Different
Leon Valley sits in a pocket where the Hill Country meets the coastal plain, and that geography shapes what we find in local ductwork. The valley floor holds older 1950s – 1970s ranch homes near the Leon Valley Golf Course, many with original galvanized steel or early flex duct that has accumulated decades of dust, pollen, and moisture. Up on the surrounding hills, newer subdivisions like Seneca and Ridgeview use more modern materials but still battle the same humid subtropical climate that keeps condensation inside ducts for months each year.
The city’s strong permitting culture and independent-minded residents mean many homeowners have maintained systems themselves, changing filters religiously while never realizing the ductwork behind the walls was still harboring buildup. Homes near the golf course present a specific profile: technicians regularly find elevated debris from mature oak and pecan trees, plus higher humidity from irrigation runoff that can kick mold growth inside trunk lines. Leon Valley’s year-round HVAC use, driven by long hot summers and short mild winters, means systems never get a seasonal break to dry out.
Our Main Leon Valley Services
We offer three core services for Leon Valley homeowners, each with its own dedicated page and local pricing.
Air Duct Cleaning in Leon Valley
Our rotary brush system from Rotobrush and negative-air machines from Nikro remove built-up dust, pollen, and mold from supply and return lines throughout your home. In Leon Valley, we pay special attention to older ranch homes with galvanized duct that may have internal corrosion, and to newer homes where flex duct has sagged in humid attics. Every job includes before-and-after photos of your own ducts. Air Duct Cleaning in Leon Valley
Dryer Vent Cleaning in Leon Valley
Lint accumulation in dryer vents is a leading cause of house fires, and Leon Valley’s mature tree cover means many vents have exterior hoods clogged with debris. We clear the full run from dryer to termination, test airflow with a gauge, and verify the exterior damper opens fully. Homes with longer vent runs through slab foundations, common in mid-century builds here, need particular attention. Dryer Vent Cleaning in Leon Valley
Duct Sealing in Leon Valley
Leaky ducts waste conditioned air into attics and crawl spaces, and in Leon Valley’s climate that means your system works harder for longer. We seal joints and gaps with mastic and metal-backed tape, then pressure-test to verify results. This is especially valuable in older homes where original ductwork has separated at seams after decades of thermal expansion. Duct Sealing in Leon Valley
