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 Houston, CA | Linden Air Duct Cleaning
Air Duct Cleaning in Houston for Lennox systems typically runs $450 to $900 for a full-system job on a single air handler, depending on how many supply runs you have and what’s growing inside them. We’re an independent Lennox service provider, not a manufacturer-authorized dealer, and the thing that sets our Houston work apart is simple: we’ve cut into enough Lennox systems across Meyerland, Spring Branch, and Westbury to know exactly where this city’s humidity hides. Call us at (980) 447-2498 for a written price before any work begins. If you own a Lennox system here, this page is for you.
Why Houston Residents Choose Us for Lennox Service
We know Lennox equipment the way a mechanic knows a specific engine family. We’ve worked on Dave Lennox Signature Collection furnaces like the SLP98V, Merit Series units like the ML180, Elite Series systems, and the 4SCU and 16ACX air conditioners. Marcus Veale, our owner, came up through the HVAC program at Los Angeles Trade-Technical College, where he learned duct systems and airflow diagnostics hands-on, and he’s spent more than a decade since then pulling apart air handlers and flex-duct runs across the city. He’s the guy neighbors call when something smells off after a renovation.
We stock Lennox-compatible flex duct, mastic, and boot hardware locally for fast Houston turnaround. We don’t wait on out-of-state shipments when your supply plenum is leaking attic air. Our Lennox sales & service experience covers the full range of residential systems, and we bring that duct-side knowledge to every job we take in our Houston service area.
Common Lennox Air Duct Cleaning Problems We Solve in Houston
Here’s what we actually find when we open Lennox systems in Houston. Not generic dust buildup. Specific failures tied to this city’s heat, humidity, and housing stock.
- Boot connections pulling free from the air handler. Lennox Signature and Elite systems installed in attics that hit 140-160°F every summer develop dry-cracked flex duct at the boot connection – an air leak that pulls unfiltered attic air straight into your supply side. You clean the ducts, then the leak re-seeds everything within a season.
- The oversized short-cycling coil problem. Houston contractors spec AC condensers for peak Gulf-Coast heat, which means oversized Lennox evaporator coils short-cycle without fully dehumidifying. The coil face stays wet, biological growth establishes on downstream duct board and blower wheels, and you get a musty smell that returns every summer. We see this pattern far more in Houston than in drier Texas markets like San Antonio.
- Flood-soaked duct board hiding mold. In post-oil-boom subdivisions near Brays Bayou – Meyerland especially – original duct-board trunk sections absorbed water during Harvey and Allison. Visible surfaces were dried and cleaned, but the interior liner still holds mold colonies that negate any surface-level cleaning.
- Torn flex-duct inner liners on aging systems. Original 15-25 year old flexible duct on older Lennox installs tears at the collar takeoff, dumping insulation fibers and attic particulate directly into supply registers. You’ll see dust accumulating on registers faster than you can wipe them.
- Flood odor that won’t quit. On a 1970s ranch in Meyerland, our crew pulled a Lennox Signature SLP98V air handler and found the duct-board return trunk still smelled of flood water a full eight years after Harvey. We HEPA-vacuumed and mechanically agitated the supply and return runs, treated the evaporator coil, and mastic-sealed the boot connections at the attic plenum. The homeowner’s musty-odor complaint cleared within two cooling cycles.
Clean ducts don’t fix everything, but dirty ones can quietly make a lot of things worse.
Lennox Service in Houston: What Local Conditions Mean for Your Equipment
Here’s a Houston-specific problem that most Lennox pages never touch: your air handler probably sits in an attic while its duct board soaks up Gulf Coast humidity year-round. That’s true in a lot of southern cities. But Houston’s flat, poorly-draining topography means a meaningful share of the housing stock has taken flood water – not once, but repeatedly. Neighborhoods along Brays Bayou, including Meyerland, saw major water in 2015, 2016, and again in 2017 with Harvey. Homeowners dried walls and replaced flooring. The internal duct surfaces, which absorbed standing water, stayed unaddressed. Years later, we cut into duct board and find the interior liner still harboring embedded mold colonies. A standard negative-air cleaning removes surface debris. It doesn’t touch what’s absorbed into the board. For Lennox owners in these neighborhoods, a full-system cleaning has to be paired with mastic resealing of the boot connections – otherwise the mold reservoir in saturated duct board re-seeds the supply side within one Houston cooling season. That’s not a generic warning. We’ve verified it in Meyerland attics, Spring Branch ranches, and Energy Corridor townhomes.
Lennox Models & Products We Service in Houston
We service the full residential Lennox line: the Dave Lennox Signature Collection (SL280V, SLP98V furnaces), the Merit Series (ML180, ML195, ML14XC1), the Elite Series (EL296V, EL16XC1), and the 4SCU, 14ACX, and 16ACX central air conditioners. When a component needs replacing, we default to OEM-spec Lennox-compatible flex duct, mastic, and boot hardware. Where the OEM configuration is no longer cost-effective at Houston attic temperatures – 15-year-old flex running through a 150°F attic doesn’t make sense to replace with the same material – we use quality aftermarket flex or metal that actually holds up. If your Lennox air handler is past its service life and the adjacent duct board is saturated, we’ll tell you plainly that duct cleaning alone is a stopgap. Staged replacement is the better spend. We’d rather tell you that before you pay for a cleaning than have you call us again in eight months.
Lennox Service Pricing in Houston
Lennox air duct cleaning in Houston costs $450-$900 for a full-system job on one air handler. A two-system home runs $800-$1,500. Evaporator coil cleaning adds $150-$300. Duct sealing with mastic runs $400-$800 depending on how many boot connections need work. What drives the cost: number of supply runs, accession difficulty in your attic, and whether the job includes coil treatment and mastic sealing. Every quote we give is written. The price is set before we start, and it’s the same price at the end. No add-ons discovered after the van is in the driveway. What a free estimate includes: a visual inspection of the air handler, coil, and accessible duct runs, plus a written scope of work with line-item pricing.

FAQs – Lennox Air Duct Cleaning in Houston
Because your duct work is in a 140-160°F attic carrying moisture-laden air from a coil that may be oversized for your home. Houston’s humidity sits above 70-80% most of the year. When a Lennox coil short-cycles because the condenser is specced for peak Gulf-Coast heat, the coil face never dries, and biological growth colonizes the downstream duct board. In flood-absorber homes near Brays Bayou, the return trunk itself may still hold moisture years after Harvey. Call (980) 447-2498 and we’ll tell you what’s actually going on in your ducts.
Yes. We use negative-pressure extraction with HEPA filtration and mechanical agitation designed for flex-duct and duct-board systems. The Signature and Elite lines use the same duct materials as the rest of the Lennox lineup. The risk of damage comes from aggressive agitation on aged flex liners, which is why we inspect inner liner condition before we start. If a liner is already tearing, we tell you before we touch it.
If the duct board absorbed standing water, cleaning alone won’t fix it. Flood water soaks into the duct board interior liner and seeds mold that survives surface cleaning. In repeatedly flooded Meyerland homes, we routinely find this. The decision comes down to what we find when we cut an inspection port: if the liner is swollen or holds visible mold, we recommend replacement of affected trunk sections. If it’s dry and intact, a full-system cleaning with mastic sealing is often enough. Call (980) 447-2498 and we’ll inspect honestly before recommending anything.
Every 3-5 years for most Houston homes, which is more frequent than the national average because of our roughly nine-month cooling season and persistent humidity. Homes with flood history, pets, recent renovation work, or allergy-sensitive occupants may need it more often. Marcus Veale has a teenage daughter with asthma, so he doesn’t oversell this – if your ducts are clean, we’ll tell you that too.
It usually does, if the source is biological growth in the ductwork or on the coil. What cleaning won’t fix is the source of the moisture that’s feeding it. That’s why we pair full-system cleaning with mastic sealing of boot connections in Houston attics. If the smell returns within a season, there’s an air leak or a moisture source that wasn’t addressed.
