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.

Why Hollis Air Duct Cleaning Is Leander’s Preferred Air Duct Cleaning Company
We’ve been serving Central Texas long enough to remember when Leander was a single stoplight and a feed store. That history matters because we’ve watched the housing stock split in real time. Our Air Duct Cleaning team has cleaned ducts in Bryson homes still under builder warranty and in original Leander proper houses with galvanized steel trunks that haven’t been opened since the Reagan administration.
Our technicians are background-checked, uniformed, and expected to operate by The Garrison Code: arrive inside the quoted window, price the job in writing before touching anything, finish by the book, and leave the site clean. Every job carries our 365-Day Done Right Promise in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday for a human voice.
Air Duct Inspection in Leander
Air Duct Inspection in Leander is where every job should start, because this city’s two housing realities demand two completely different scopes. An inspection with our video camera system lets us see whether we’re chasing builder drywall dust in a 2019 Palmera Ridge flex-duct system or decades of accumulated debris and disconnected joints in a pre-2000 home near Main Street. The inspection itself runs $150 – $250 and is credited toward the cleaning if you move forward.
What the Camera Reveals
We feed a self-leveling color camera through every accessible trunk and branch, recording as we go. In Leander’s newer subdivisions, we’re typically documenting crushed flex runs from post-construction landscaping, loose collars at plenum connections, and drywall dust that settled during the builder’s punch-list phase. In older homes, we’re looking for rusted galvanized seams, disconnected take-offs, and gaps where the original duct sealant has turned to powder.
When to Schedule an Inspection
Request an inspection before move-in if you’re buying new construction along the 183A corridor, especially if the builder’s warranty is still active. For older Leander homes, schedule when you notice uneven room temperatures, musty odors when the AC cycles, or visible dust pluming from registers. The inspection gives you documented evidence, either for the builder or for your own maintenance planning.
Residential Air Duct Cleaning in Leander
Residential Air Duct Cleaning in Leander is not one service. It’s two services that happen to share a name. On the west side of the 183A corridor, in communities like Crystal Falls, Bryson, Palmera Ridge, and Travisso, we’re primarily removing construction debris from systems less than 20 years old. Near historic downtown Leander and the original railroad grid, we’re performing deep source removal on decades of accumulated grime, then sealing the joints and seams that let it all back in. Full system cleaning runs $350 – $650 depending on system size, accessibility, and whether sealing work is needed.
New-Construction Debris Removal
Post-2010 homes in Leander’s master-planned communities were often occupied before the ductwork was properly cleaned. We put the entire system under negative pressure using a Nikro HEPA-filtered collection unit, then use rotary brush agitation to dislodge drywall dust, sawdust, and stray insulation from the trunks and branches. The evaporator coil and return plenum get particular attention, since summer condensate on Leander’s humid July afternoons turns that debris into a mold-friendly paste.
Older Home Deep Cleaning and Sealing
Homes built before Leander’s growth explosion often have original metal ductwork with failing sealant and disconnected joints. We remove the accumulated material with the same professional-grade equipment, but the critical step is sealing. We apply duct sealing mastic to every joint, collar, and seam, then pressure-test to verify. Without this step, the cleaning is temporary. The leaks that pulled attic dust and pollen into your system for thirty years will keep doing it.
Trusted Brands We Service in Leander
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for containment and collection, and filtration products from Honeywell, Aprilaire, and Abatement Technologies. We don’t show up with shop-vacs and extension poles. The same tools we run in Leander homes are specified for commercial healthcare and institutional jobs. If your system includes Honeywell or Aprilaire media filters, we stock replacement cartridges and can swap them during the cleaning visit, so you’re not making a second trip to the hardware store on Bagdad Road.
Common Air Duct Cleaning Problems We See in Leander Homes
- Crushed flex runs from post-construction landscaping. In Crystal Falls and Travisso, we’ve found dozens of second-floor branches pinched nearly flat where slab crews trenched after final grading. The blower motor pulls high amps, upstairs rooms starve for airflow, and no amount of register cleaning fixes it. Camera inspection finds it; replacing the crushed section with rigid duct fixes it.
- Drywall dust and construction debris in new systems. Builders in Leander’s 183A corridor subdivisions often leave the ducts full of material from framing, insulation, and finish work. The first homeowner breathes it for months. We document it with before-and-after video for warranty claims.
- Disconnected joints in older downtown homes. Original ductwork near Leander’s historic core has survived decades of thermal cycling. The sealant cracks, screws back out, and suddenly your attic is part of your return path. Cleaning without sealing just gives the debris a fresh start.
- Mold and allergen loading at the evaporator coil. Leander’s year-round HVAC runtime and heavy cedar pollen in winter create a film on the coil and return plenum that standard filter changes never touch. We clean the coil housing and treat the plenum as part of every full system scope.
Pricing for Air Duct Cleaning in Leander, TX
A typical residential air duct cleaning in Leander runs $350 – $650 for a complete supply-and-return system with up to 15 registers. Smaller homes or single-zone systems sometimes fall in the $300 – $400 range. Larger two-story homes with 20+ registers, multiple HVAC units, or significant sealing work can reach $750 – $950. Commercial systems are priced by square footage and unit count, usually starting around $800.
What moves the price: system size, number of registers, accessibility of the air handler, whether the evaporator coil needs cleaning, and whether we find disconnected or crushed ductwork that needs repair. We do not quote per-vent pricing. We do not bait with a low coupon and add charges at the door. The price is written down before any work starts, and it does not move.

FAQs About Air Duct Cleaning in Leander
Yes, if it was never cleaned after construction. In Leander’s post-2010 subdivisions, we regularly find drywall dust, sawdust, and insulation scraps that the builder’s crew never removed. That debris circulates through your system and loads your filters prematurely. Call (361) 326-5060 for a camera inspection that will show you exactly what’s in there.
Decades of accumulated dust and pollen, rusted galvanized steel seams, and original sealant that has turned to powder. The downtown grid homes also have more disconnected joints where thermal cycling and settling have pulled the ductwork apart. Deep cleaning alone isn’t enough; sealing the joints with mastic is what keeps the problem from returning. We price both steps in writing before starting.
Most often, a crushed or disconnected flex run. In Crystal Falls we opened the return drop on a 2016 two-story and found the flex run from the second-floor trunk crushed nearly flat where the builder’s slab landscaping crew had trenched after the yard was graded. The master bedroom was getting almost no airflow and the blower motor was pulling high amps against the restriction. We cut in a new rigid trunk-and-branch stub, sealed the collar with mastic, put every supply and return under negative pressure with HEPA filtration, and used agitation tools to knock loose the drywall dust that had settled in the plenum since move-in. Amps dropped back into range and the upstairs rooms finally balanced. Camera inspection catches this; cleaning alone does not.
It affects where the problem concentrates. Leander’s winter and spring cedar season loads the return side and evaporator coil with sticky, dense pollen that standard filters don’t fully stop. Combined with summer condensate moisture, that pollen becomes a recurring mold and allergen source in the plenum and coil housing. We target those components specifically, not just the visible supply registers.
We provide before-and-after video inspection of the ductwork, plus photos of the debris collected. You see the condition of the trunks and branches before we start, and you see them after. If we performed sealing work, we pressure-test and show you the leakage reduction. Documentation is part of The Garrison Standard. Call (361) 326-5060 to schedule an inspection and see for yourself what’s in your system.
