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.

AfterLennox Air Duct Cleaning in Austin, CA | Hollis Air Duct Cleaning
Hollis Air Duct Cleaning provides independent Lennox air duct cleaning across Austin, and we’re not a manufacturer-authorized shop, which means our advice isn’t shaped by a warranty line. The one thing that makes our Lennox work here different is that we map Austin’s two distinct duct-debris profiles onto the specific Lennox series in each home: new-build construction dust out in Kyle and Cedar Park, versus decades of cedar and oak pollen in Hyde Park and Travis Heights bungalows. Call (361) 326-5060 for a free estimate and a straight answer about what’s actually inside your ducts.
Key Takeaways:
- Independent Lennox specialists serving every Austin housing era since 2004, led by Roy Castellanos.
- Written price before any work starts, backed by the 365-Day Done Right Promise.
- We know which Lennox failure modes show up in central Austin pier-and-beam homes versus west-side flex-duct runs.
Why Austin Residents Choose Us for Lennox Service
Roy Castellanos grew up in Boyle Heights and trained at Los Angeles Trade-Technical College, then spent years doing hands-on duct work before starting Hollis Air Duct Cleaning. That background matters here in Austin, because our Air Duct Cleaning - Austin team has cleaned Lennox systems in every housing era this city has, from 1920s Cherrywood bungalows with retrofitted trunk lines to Round Rock tract homes with factory-flex runs that never got properly sealed. Every technician who walks into your home is background-checked and uniformed, and the price is written down before we touch a single vent. We use OEM Lennox-compatible parts where exact fit matters, and quality aftermarket components where it doesn’t. And if the work fails within a year, the 365-Day Done Right Promise brings us back at no charge, no negotiation.
Common Lennox Air Duct Cleaning Problems We Solve in Austin
- Return leaks loading the air handler with pollen. Lennox high-efficiency units with sealed combustion and variable-speed blowers pull harder on return ducts than older single-stage systems. In central Austin pier-and-beam homes from Hyde Park to Rosedale, we regularly find return plenums leaking at the cabinet seam, bypassing the filter and pulling cedar and oak pollen straight into the blower wheel. We seal the return, clean the blower assembly, and the system moves air the way Lennox designed it to.
- Biological growth on the evaporator coil. Merit and Elite series coils in Austin’s year-round cooling cycle rarely get a dry-out window. From June through September the AC runs almost continuously, and when return-side filtration is undersized or poorly sealed, the evaporator face becomes a damp substrate for mold and biofilm. We clean the coil face, correct the filtration, and show you before-and-after photos so you can see the difference.
- Caliche dust coating the blower wheel in west-side homes. Westlake and Bee Cave sit on limestone and caliche hills, and summer attic temperatures hit 130 to 140°F. Long, undersized flex-duct runs in unconditioned attics sweat and degrade, and the blower wheel ends up coated in fine alkaline dust pulled through the supply trunk. This failure pattern is specific to Austin’s west side, and we clean it differently than a pollen-loaded central Austin system.
- Drywall dust and fiberglass particulate in new-build systems. New Lennox systems installed in Round Rock, Cedar Park, and Kyle frequently have mastic-starved joints at the plenum and takeoff collars. The first cooling season pushes drywall dust and fiberglass insulation particulate through the entire duct system. We seal those joints with mastic, clean the runs, and the system stops circulating construction debris through your air.
- Crushed and kinked flex duct from attic work. Austin homes with attic access see a lot of foot traffic, from cable installers to pest control to holiday storage runs. Crushed flex runs choke airflow and make a Lennox system work harder than it should, which drives static pressure up and comfort down. We repair or replace the damaged runs, seal the takeoffs, and the blower stops fighting restrictions it shouldn’t have to fight.
Lennox Service in Austin: What Local Conditions Mean for Your Equipment
Austin’s explosive growth has stacked brand-new high-density construction directly beside 1950s bungalows, so a single Lennox duct cleaning route in this city can move from drywall-dust-packed flex runs in a Kyle new-build to a Hyde Park pier-and-beam return that has drawn in seventy years of cedar and oak pollen. Those are two completely different debris profiles, and they demand two completely different Austin Dryer Vent Cleaning approaches. A new-build system needs construction debris removal and mastic sealing at the joints. An older central Austin system needs return sealing, coil cleaning, and filter correction. This is why a generic duct cleaning route that treats every house the same will fail in Austin: the homes were not built the same way, and neither was the debris. In Travis Heights, we pulled a Lennox Elite EL296V air handler that had been short-cycling all summer because the return plenum was leaking at the cabinet seam and pulling attic air past the filter. The blower wheel was coated in a mat of cedar pollen and caliche grit. We cleaned the evaporator coil, resealed the return with mastic, repaired two crushed flex runs in the attic, and the system’s static pressure dropped enough that the homeowner noticed quieter operation and better humidity control within the first week. That’s not a generic outcome, and it doesn’t come from a generic process.
Lennox Models & Products We Service in Austin
We work on Lennox residential equipment across the full product range. The Merit Series, including the 14ACX, ML14XC1, and ML180, shows up most often in Austin’s suburban tract homes and new-builds. The Elite Series, including the EL16XC1, EL296V, and SL280V, is common in central Austin retrofits and higher-end remodels. The Dave Lennox Signature Collection, including the XC21, XC25, and SL25XPV, appears in custom homes and high-efficiency replacement jobs. We also service Lennox iComfort and iHarmony zoning systems. Our parts approach is straightforward: OEM Lennox-compatible components for blower wheels, coil panels, and control boards where calibration matters, and quality aftermarket duct components, mastic, and insulation where the application allows. We stock common duct repair materials locally for fast Austin turnaround, which means a flex-run repair doesn’t wait on a parts truck from Dallas.

Lennox Service Pricing in Austin
Air duct cleaning for a Lennox system in Austin typically runs $450 to $950 for a whole-home cleaning, depending on square footage, number of returns, and how heavily loaded the system is. Evaporator coil cleaning adds $150 to $300 when it’s done as part of the duct job. Flex duct repair runs $200 to $500 per run depending on length and access. Return duct cleaning alone starts around $250. What drives the cost in Austin specifically is debris type: a heavily pollen-loaded 1950s return in Hyde Park takes more time than a lightly dusted new-build in Kyle. Every job gets a written price before any work starts, and that number does not move at the door. For an exact quote on your Austin system, call (361) 326-5060, and we’ll give you a straight number.

FAQs – Lennox Air Duct Cleaning in Austin
Yes, in most Hyde Park era homes that smell is biological growth on the evaporator coil or inside the return plenum, and it’s being pushed through the house every time the blower runs. Homes of that era often have return plenums that were never sealed at the cabinet seam, so they pull damp crawlspace or attic air past the filter, and the coil surface never fully dries. We diagnose the return leak, clean the coil and blower assembly, and seal the return with mastic. For a diagnosis you can see with your own eyes, call (361) 326-5060.
New ducts in Kyle should be at least inspected, because they often need cleaning before the first summer is over. New-build Lennox systems in Austin’s fast-moving subdivisions frequently have mastic-starved joints at the plenum and takeoff collars, and the first cooling season pushes drywall dust and fiberglass particulate through the entire duct system. We find this often enough that we treat it as a known issue, not an exception. The fix is cleaning the runs and sealing the joints properly.
Yes, and harder than you’d expect. Austin’s late-winter and early-spring cedar fever season puts enormous volumes of mountain cedar and oak pollen into the air, and return-side leaks in older central Austin homes pull that pollen directly into the air handler, bypassing the filter entirely. We see Lennox blower wheels in Travis Heights and Rosedale with a solid mat of cedar and oak pollen on the wheel face, which reduces airflow and adds load to the blower motor. Cleaning the wheel and sealing the returns directly addresses what Austin’s pollen season does to your system.
What you’re seeing is attic temperature and humidity attacking the duct. In Austin’s west-side hills, including Westlake and Bee Cave, summer attic temperatures climb to 130 to 140°F, and long flex-duct runs in unconditioned attics sweat and degrade. The outer jacket breaks down, the insulation compresses, and dust and caliche grit get pulled into the airstream. The fix is inspecting the full run, repairing or replacing the damaged sections, and sealing the takeoff collars. Sweaty flex duct is a symptom of a duct system that’s working against the Hill Country climate, not with it.
No, air duct cleaning does not void a Lennox equipment warranty when done properly with professional equipment. We’re an independent service provider, not a Lennox authorized dealer, so we don’t represent or act on behalf of the manufacturer. We use professional-grade negative-air machines and rotary brush systems from Rotobrush, Nikro, and Abatement Technologies, and we never recommend anything that would compromise the manufacturer’s design intent. If you’d like a specific answer for your exact model and situation, call (361) 326-5060 and we’ll tell you what we’d do.
