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.
Fast, Reliable Air Duct Cleaning Across Sonterra
Air duct cleaning in Sonterra runs $450 – $900 for a single zoned system, and most homes here have two or three. That’s the honest starting point. If someone quotes you $199 for a whole Sonterra house, they’re selling a bait-and-switch, not a duct cleaning. We’re Linden Air Duct Cleaning, part of the Threshold Group family since 2004, and we price this work by the system, not the square foot. That’s the only honest way to quote a 1990s Stone Oak luxury build with attic-routed flex duct that’s been breathing San Antonio cedar pollen for twenty-plus years. Call (980) 447-2498 and you’ll get a live person who can walk you through what your specific house actually needs.
Why Linden Air Duct Cleaning Is Sonterra’s Preferred Air Duct Cleaning Company
Sonterra homeowners tend to ask harder questions than most, and we like that. They want to know who’s walking through the door, what the job will cost before the van pulls up, and what happens if something isn’t right. Those are the right questions. The Threshold Standard answers them: every technician is background-checked, identity-verified, and photo-badged. Before your appointment, you get the tech’s name and photo. When they arrive, they show their ID at the door. No exceptions. It’s a simple protocol, and it’s why people who are home alone, parents with young children, and older homeowners in Sonterra call us back.
Our crews work Sonterra regularly. We know the streets off Sonterra Boulevard, the gated sections, and the back loops where the big custom builds sit on oversized lots. We coordinate dispatch from our Dallas-Fort Worth office, but the crews serving Sonterra are local and familiar with the housing stock here. That matters when you’re pulling camera down attic-routed flex duct that’s been baking in San Antonio attic heat since the Clinton administration.
The work carries a written 365-Day Done Right Promise. If the job isn’t right, we make it right. In writing, on every job. No handshake deals. No “trust us” from a guy standing in your hallway. This is our Air Duct Cleaning team’s standing commitment, not a promotional offer.
Vent Cleaning in Sonterra
Vent cleaning in Sonterra means pulling visible registers, cleaning them, and cleaning the immediate boot behind each one. It does not clean the full duct runs. That’s a distinction every Sonterra homeowner should understand before they pay for it. In a 4,000 sq ft home with three zoned systems, there can be 18 to 24 supply registers and a dozen returns. Cleaning them properly takes time, and it’s worth doing right. Expect vent cleaning alone to run $150 – $300 depending on register count and accessibility.
Register and Boot Cleaning
Every register comes out, gets scrubbed, and the boot behind it gets vacuumed with a HEPA-equipped extractor. In Sonterra kitchens, we consistently find a layer of cooking grease trapped in the register fins that has bonded with caliche dust. That film doesn’t just wipe off. It takes agitation and a proper degreaser, then a final wipe before the register goes back.
Return-Side Vent Cleaning
Return vents in Sonterra’s two-story builds pull air up from the first floor and down from the second, and they catch everything: pet hair, dust, and the fine white caliche limestone powder that drifts in from the Hill Country edge. If a crew skips the return side, which happens more than it should, they’ve left the job half done. We clean every return, every time, and document it.
Ductwork Cleaning in Sonterra
Ductwork cleaning in Sonterra is source removal, not vent wiping. It means negative-pressure extraction at each air handler, agitation tools run through every supply and return run, and HEPA filtration on the exhaust side. In a single-system home, budget $450 – $700. For a two-system home, $700 – $1,200. For three systems, which is common in the larger custom builds off Sonterra Boulevard, $1,100 – $1,800. The price is per system, written before any work begins.
Negative-Pressure Extraction
This is the industry term for pulling a vacuum on the duct system while we agitate the interior walls. It’s not a shop vac stuck in a register. We seal the system at the air handler, run proper extraction, and capture what comes out. In Sonterra attics, that extraction pulls out years of Ashe juniper pollen, caliche dust, and the occasional lizard skeleton. We’ve seen it all.
Flex Duct Liner Inspection
Sonterra’s 1990s-era flex duct has an inner liner that degrades over time. It separates, corrugates, and creates folds where pollen and dust pack in tight. No filter change touches those folds. During ductwork cleaning, we run camera inspection down the runs to check liner condition, and we document what we find. If a liner has failed, we tell you and quote the repair separately. We don’t clean a broken duct and call it good.
Trusted Brands We Service in Sonterra
We run professional-grade equipment from Nikro for extraction and agitation, and we use air-quality products from Honeywell and Aprilaire when a Sonterra homeowner wants filtration upgrades after we finish cleaning. Most of the homes we service in Sonterra have original builder-grade Honeywell thermostats and Aprilaire media cabinets. We know those systems. We stock common parts and filters for them, which means fewer return trips and faster turnaround when your cleaning reveals a component that needs replacing. Our techs train on Rotobrush systems too, so if your home has an older Rotobrush-installed duct array, we know how it was built and how to clean it properly.
Common Air Duct Cleaning Problems We See in Sonterra Homes
- Separated flex duct liners trapping cedar pollen. Two decades of San Antonio’s December-through-February cedar season leaves a pollen mat inside separated liner folds that only source-removal cleaning touches. We spot this during camera inspection, not after the job.
- Caliche limestone dust settled in return runs. The fine white dust from the Hill Country edge settles in return ducting where air moves slower, and it’s often invisible because the registers sit high on walls. It comes out gray and chalky on extraction day.
- Condensation damage in attic-routed insulation. San Antonio’s humid spring storms push moisture into attics, and aging duct insulation can absorb it. We find damp, degraded insulation on exterior runs more often in Sonterra’s older builds than anywhere else we work.
- Multi-zone systems where one zone was never cleaned. Three-system homes sometimes get quoted as one flat rate, and the crew runs out of time before touching the third air handler. We price per system precisely so that doesn’t happen.

FAQs About Air Duct Cleaning in Sonterra
Because you have three systems, each with its own air handler, its own duct runs, and its own return-side work. A three-system Sonterra home typically runs $1,100 – $1,800 to clean properly. A single-system home in central San Antonio runs $450 – $900. The difference is labor and time in the attic, not markup. If a quote seems suspiciously low for a large Sonterra home, ask whether it covers all three air handlers. Call (980) 447-2498 and we’ll give you a per-system written quote.
Cedar season, driven by Ashe juniper, runs December through February, and it fills Sonterra attics with pollen that enters return ducts and packs into the separated folds of aging flex duct liner. Homeowners sometimes notice a dusty, slightly acrid smell when the heat kicks on in January. That’s the pollen. Camera inspection shows it as a yellow-brown mat in the liner folds. Proper source-removal cleaning with HEPA filtration addresses it directly. Call (980) 447-2498 to schedule an inspection.
You should get before-and-after photos of supply and return runs, camera inspection stills from the air handler side, and a record of what was pulled out. A MERV reading at each blower motor is standard on our jobs. If you can’t see the ducts from your living room, the only proof you have is the documentation the company hands you. We hand you full documentation on every job, with the 365-Day Done Right Promise attached. Call (980) 447-2498 and ask what you’ll receive.
Caliche dust is a fine white chalky powder that settles in duct runs and coats duct walls over time. In Sonterra homes near the Hill Country edge, it gathers in return runs especially, and it can mix with humidity to form a paste that hardens the flex liner. Left sitting, it reduces airflow and makes your system work harder. Source removal is the only way to get it out. Call (980) 447-2498 for an estimate.
No. Vent cleaning covers registers and boots, which runs $150 – $300. Whole-system ductwork cleaning, meaning full supply and return runs with negative-pressure extraction, runs $450 – $900 per system. A three-system Sonterra home needs all three done to actually clear the air. We’ll quote both options separately and in writing, so you know exactly what you’re paying for. Call (980) 447-2498.
