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 San Antonio, CA | Linden Air Duct Cleaning
Air Duct Cleaning in San Antonio for Lennox systems typically runs $450 to $900 for a full system, depending on home size and how much debris has settled into the trunk lines. We’re an independent provider, not a Lennox dealer, which means we tell you straight what your ductwork actually needs rather than what the manufacturer’s playbook suggests. The thing that sets our Lennox work apart here: we know what mountain cedar season does to these specific systems, and we inspect for the joint failures that most brushes never reach. Call (980) 447-2498 for a written quote before any work starts.
Why San Antonio Residents Choose Us for Lennox Service
We’ve opened enough Lennox furnaces across San Antonio to know exactly how the Merit Series in a 1980s Converse ranch differs from a Dave Lennox Signature Collection install in an Alamo Ranch new build. Marcus Veale, our owner, learned airflow diagnostics and duct systems hands-on through the HVAC program at Los Angeles Trade-Technical College, and he’s spent more than a decade since then inside real attics and furnace closets. That background matters when your Lennox Healthy Climate cabinet has been inhaling Ashe juniper pollen for six straight weeks.
Every tech we send to your door is background-checked, identity-verified, and photo-badged under the Threshold Standard. You get the technician’s name and photo before the visit. The price you’re quoted is the price you pay, in writing, every time. And every repair carries a 365-Day Done Right Promise: if it fails, we come back at no charge. That’s not a promotion. It’s how we’ve operated since 2004 as part of the Threshold Group family. We also stock genuine Lennox OEM media filters and cabinet hardware locally, so San Antonio turnaround on Healthy Climate and Signature Series systems stays fast.
Common Lennox Air Duct Cleaning Problems We Solve in San Antonio
- Mountain cedar loading in Healthy Climate MERV-16 cabinets. During December through February, San Antonio’s cedar counts spike to extreme levels. The MERV-16 media in Lennox Healthy Climate cabinets clogs fast, the blower works harder, and ultra-fine pollen gets pulled downstream into the supply trunk. We replace the media and clean the entire downstream run, not just the cabinet.
- Separated flex boots on 1980s Merit and Elite trunks. The ML180 and EL195 single-stage furnaces common in San Antonio’s 1970s-to-1990s ranch homes often ran undersized returns. In attic-routed installs, the original flex boots have separated at the plenum, creating debris pockets that standard brush equipment passes right over.
- Caliche dust spikes in Signature Series systems. The XC21 and XC25 variable-capacity units paired with older slab-on-grade metal trunk ductwork see return-air static climb when the corroded trunk fills with fine mineral dust drawn in through leaky attic returns on windy spring days.
- Cracked flex collars on attic-routed HRV and bypass humidifier runs. San Antonio attics hit 140°F and beyond through summer. Older Lennox Healthy Climate bypass humidifier and HRV flex collars crack in that heat, leak moisture and dust into the return trunk, and compound the allergen load right after cedar season ends.
- Post-construction dust in far-northwest new builds. The Alamo Ranch and Helotes corridor boom has produced tens of thousands of new homes where drywall dust settles inside brand-new Lennox ductwork before anyone ever turns the system on. A full negative-pressure extraction before move-in saves years of recirculated gypsum fines.
Lennox Service in San Antonio: What Local Conditions Mean for Your Equipment
San Antonio’s Northeast-side Randolph AFB corridor, the residential belt around Universal City, Converse, and Schertz, has an unusually dense cluster of early-1980s builder-grade Lennox systems. These homes share a specific failure pattern we rarely see at the same rate anywhere else: the original sheet-metal trunks have corroded at the flex-boot collar attachments, so the visible debris inside the duct is only half the problem. The joint itself has to be resealed before any brush or negative-pressure wand can pull the trapped material out. In a 1983 ranch off Pat Booker Road in Universal City, we opened a Lennox ML180 furnace closet and found the return trunk corroded at the flex-boot collars with visible separation at two branch takeoffs, classic for that Randolph AFB-era build. We re-mastic’d the collars, re-secured the flex runs, then ran a full-system clean with video inspection. The homeowner told us the cedar-season sneezing in the master bedroom finally stopped. That sequence, diagnose the joint first, then clean, is what San Antonio Lennox owners actually need, because an eight-month cooling season means your system cycles enormous air volume through attic ductwork from April into November, and every compromised collar is a dust trap feeding your supply runs.
Lennox Models & Products We Service in San Antonio
We work on the full residential Lennox range in San Antonio. That covers the Merit Series, including the ML14XC1 air conditioner, ML180 single-stage furnace, and ML193; the Elite Series, including the EL16XC1, EL195, EL296, and SL280; and the Dave Lennox Signature Collection, including the XC21, XC25, and SLP98. We also service Lennox Healthy Climate whole-home air cleaners, bypass humidifiers, and HRV/ERV units. For parts, we install genuine Lennox OEM media filters and cabinet hardware when a Healthy Climate or Signature Series system needs an exact fit. On the distribution side, we use quality aftermarket flex duct, mastic, and boot collars where OEM isn’t necessary. If a Lennox trunk is corroded beyond re-sealing at the boot collars, we’ll tell you that honestly rather than sell a cleaning that will fail again within a season. You can also reach us through our broader Lennox sales & service page if you’re weighing repair versus replacement.
Lennox Service Pricing in San Antonio
A full Lennox air duct cleaning in San Antonio runs $450 to $900 for a complete system. That’s one flat price per system, agreed in writing before work begins, not a per-vent estimate that balloons once the van is in your driveway. What moves the number: square footage, number of returns, how much cedar pollen and caliche dust has accumulated, and whether flex boot separations need re-mastic work before cleaning can be effective. If trunk corrosion or separated collars are found during inspection, we quote that repair separately and you decide before any work proceeds. The estimate is free, and the tech who arrives is the tech whose name and photo we sent you. Call (980) 447-2498 for an exact quote on your Lennox system.

FAQs – Lennox Air Duct Cleaning in San Antonio
No. We’re an independent provider, not authorized, sponsored, or endorsed by Lennox, and cleaning a Healthy Climate media cabinet doesn’t require dealer status. What it requires is knowing the cabinet’s airflow path, the correct MERV-16 media fitment, and how a clogged media pad affects your blower. We stock genuine Lennox OEM filters for these cabinets in San Antonio, so replacement media comes from Lennox while the labor and warranty come from us. Call (980) 447-2498 if you’re due for media replacement.
That’s mountain cedar season. Ashe juniper pollen peaks December through February in San Antonio at levels that routinely reach extreme on allergen charts. The fine pollen loads into your Merit Series return, clogs whatever media you’re running, and the dusty smell is the blower pulling through loaded ductwork every time the heat kicks on. A full cleaning removes the accumulated pollen and the source of the odor, not just the symptom. Call (980) 447-2498 for a quote.
In most cases, yes. We run negative-pressure extraction through the existing registers with the system sealed, then video-inspect the trunk and branch runs as part of our San Antonio Dryer Vent Cleaning process. Where early-1980s Schertz systems have the classic corroded flex-boot collars, those joints must be re-mastic’d and re-secured before cleaning will hold, and that work is done in place without tearing out drywall.
Yes. The XC25’s variable-capacity blower responds to static pressure changes, which means debris accumulation and return-side restrictions affect airflow differently than a fixed-speed Merit blower. We treat Signature Series systems with specific attention to return-air static, media cabinet condition, and any attic-routed flex collar deterioration before running the full clean.
Every three to five years for most San Antonio homes, but if you live near the Randolph AFB corridor with an original 1980s trunk, or in a far-northwest new build with construction dust in the ducts, schedule the first one sooner. After a heavy cedar season, if anyone in the house has asthma or allergies, a post-January cleaning makes a measurable difference. Call (980) 447-2498 and we’ll give you a straight answer about whether your system actually needs it this year.
