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 Company in Helotes, TX
Air duct cleaning in Helotes typically runs $350 – $650 for a whole-home system, with most jobs scheduled within a few business days. We’re Hollis Air Duct Cleaning, and we’ve built our work here around a specific problem: Helotes’s Hill Country cedar pollen and ongoing new construction leave attic ductwork holding far more allergenic debris than systems in flatter, more established parts of Bexar County. Our crews use Rotobrush rotary systems and Nikro negative-air machines to pull that material out, and we put the price in writing before we start. Call (361) 326-5060 for a free estimate.
Why Helotes Homes Are Different
Helotes sits at the edge of the Texas Hill Country, and that geography changes what we find in ducts. The cedar pollen that gives locals “cedar fever” from December through February doesn’t stay outside. It gets pulled through return vents, past the filter, and into flexible ductwork running through hot attics. We’ve opened systems in Helotes homes where the interior coating was visibly green-gray with pollen residue from multiple seasons.
The housing stock here is split between older ranch homes built in the 1970s and 1980s, many with original flexible ductwork that’s brittle or sagging, and newer custom builds on acre-plus lots with longer duct runs and more elbows where debris collects. Both types tend to have attics that hit 140°F in July and August, baking dust and pollen into the duct walls. New construction in outlying areas adds another layer: drywall dust, wood framing particles, and insulation fragments that builders’ rough cleanups miss. We see this in homes off Bandera Road and in the rolling lots west of FM 1560, where the building boom of the last decade has been concentrated.
HOAs in Helotes generally don’t require permits for duct cleaning, though some gated communities near Grey Forest or Scenic Loop Road ask for vendor insurance certificates. We handle that paperwork when needed.
Our Main Helotes Services
Helotes homeowners call us for three jobs, each handled on its own dedicated page below.
Air Duct Cleaning in Helotes
We clean the full supply and return network with a Rotobrush rotary brush system that scrubs the duct walls, followed by a Nikro negative-air machine that pulls loosened debris out of the house entirely. In Helotes, we pay special attention to pollen buildup in flexible attic runs and to construction debris in newer builds. Every job gets a written price upfront and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Helotes

Dryer Vent Cleaning in Helotes
Dryer vents in Helotes often run 15 – 25 feet through attic space to exterior wall caps, with multiple bends that trap lint in the Hill Country humidity. We use rotary brushes and high-velocity air tools to clear the full run, then verify airflow at the termination. Longer vent paths are common in the larger-lot homes here, and partial cleanings leave fire risk intact. Dryer Vent Cleaning in Helotes

Duct Sealing in Helotes
Leaky ducts in Helotes attics waste cooled air into 140°F spaces and pull pollen and fiberglass insulation into the breathing air. We seal joints and connections with mastic and metal-backed tape, then pressure-test the system to verify the seal. Older flexible ductwork in 1970s – 1980s ranch homes here often has gaps at the plenum connection that standard cleaning won’t fix. Duct Sealing in Helotes
