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 | Kestrel Air Duct Cleaning
We provide independent Lennox Air Duct Cleaning - Houston, and the work here is different from anywhere else because of one fact: Houston’s subtropical humidity turns routine dust into a biological problem inside Lennox ductwork. Moisture that never fully dries means mold, not just debris, is what we’re removing from Lennox systems in this city. We’re not affiliated with or authorized by Lennox, but we’ve cleaned the ductwork behind their furnaces and air handlers in Houston homes for years, and we know exactly what the Gulf Coast climate does to them. Call (469) 972-3151 for a free estimate, and you’ll get a written price before we touch a single vent.
Why Houston Residents Choose Us for Lennox Service
Lennox builds solid equipment, but Houston builds the conditions that stress it. Our crews work on Lennox sales & service ductwork across this city’s mixed housing stock, from 1960s Spring Branch ranches to post-Harvey rebuilds in the Energy Corridor. Dale Whitmore, our owner, grew up in the San Fernando Valley and cut his teeth on general HVAC maintenance before spending over a decade focused on the duct side. He trained at Los Angeles Trade-Technical College, where airflow and filtration became the work, not just a side note.
What that means for you: we know Lennox variable-speed air handlers, we know sealed combustion furnaces, and we know how flex duct routed through a 140-degree Houston attic behaves after twenty summers. We use OEM-spec or equivalent-quality aftermarket flex duct, mastic, and insulation. No cheap foil tape as a permanent fix. When we tell you a Lennox system needs sealing rather than full replacement, it’s because the evidence supports it, not because we’re trying to upsell you.
Every visit runs on the Kingswell Guarantee: a written price before work begins, a defined arrival window, a clean job site, and a written 365-Day Done Right Promise. The price in your hands before a vent is opened isn’t a promotion. It’s how we’ve operated since 2004.
Common Lennox Air Duct Cleaning Problems We Solve in Houston
- Sweating supply registers and plenums. Houston summers push humidity above 75% for weeks. When a Lennox air handler sits in an unconditioned attic and the supply registers bead with condensation, the duct insulation has likely failed. The damp interior becomes a mold host inside the plenum. We inspect, identify the failed section, and clean or replace it.
- Brittled fiberglass duct board from attic heat. Homes built in Houston’s 1960s-through-1980s boom, especially in Sharpstown and Westbury, often still run original fiberglass duct board. Decades of 140°F attic temperatures plus moisture cycles leave the inner liner shedding fibers into the airstream. We seal and encapsulate where the structure is sound, and replace only where contamination is structural.
- Return air leaks pulling attic dust into Lennox blowers. Loose return connections let Houston’s fine attic dust and insulation particles bypass the filter. On Lennox variable-speed blowers, that imbalance causes premature motor wear. We find the leak points, seal them with mastic, and clean the blower cabinet.
- Silt lines and mold roots from flooding. In Meyerland, Braeswood, and Westbury, homes that took water in Allison, Harvey, or both often had insulation replaced but never opened the ductwork. We routinely pull back duct sections and find embedded silt lines and mold root systems penetrating the duct board. This is a Houston-specific failure mode, and it’s structural.
- Near-year-round cooling load hiding contamination. Houston’s cooling season runs March through November. Lennox systems here never get the extended shutdown that lets duct interiors dry and self-regulate. Moisture-laden return air cycles through almost continuously, sustaining the damp conditions mold and dust mites need. That’s why we treat duct cleaning in Houston as a remediation service, not a dust-removal chore.
Lennox Service in Houston: What Local Conditions Mean for Your Equipment
Here’s what makes Houston different, and it’s specific to this city: the flood history. Meyerland and Braeswood took water in both Tropical Storm Allison in 2001 and Hurricane Harvey in 2017. Homeowners mitigated the visible damage, replaced drywall and flooring, but never opened the duct system. We’ve pulled back duct board in those neighborhoods and found silt lines two inches up the inner liner, with mold roots growing through the board itself. That contamination layer doesn’t exist in drier cities. It’s not a generalized “ducts get dirty” problem. It’s a Houston problem, and it requires opening the system, not just running a brush through it. For Lennox owners specifically, this matters because their air handlers pull return air through those flooded return plenums every single cycle. The equipment keeps running fine. The air it moves doesn’t.
Lennox Models & Products We Service in Houston
We work on ductwork behind Lennox’s main residential lines, including the Dave Lennox Signature Collection (SL280V, SL297NV, EL296V), the Merit Series furnaces and air handlers (ML180, ML193, ML196), and Elite Series air conditioners and heat pumps (EL16XC1, EL18XPV). We also service homes running Lennox iComfort and iHarmony zoning systems. For Houston turnaround, we keep OEM-spec flex duct, mastic, and R-8 insulation on the truck. When an older Lennox system has duct board that’s borderline, we’ll recommend sealing and encapsulation over full rip-out unless the contamination is structural. That call comes from evidence, not convenience.
Lennox Service Pricing in Houston
Most Lennox air duct cleaning jobs in Houston run between $450 and $900 for a full system, depending on square footage, number of returns, and whether we’re also sealing leaks or replacing damaged flex runs, and we can bundle our Dryer Vent Cleaning in Houston if needed. Flood-affected homes with embedded contamination run higher because the work is more involved. What drives the price: how much duct is accessible, what condition the inner liners are in, and whether biological growth requires more than mechanical cleaning. Every free estimate includes a written price before work begins. Call (469) 972-3151 and you’ll know the number before we open a register.

FAQs - Lennox Air Duct Cleaning in Houston
Houston’s relative humidity sits above 75% most of the year, while Dallas is far drier. Mold needs sustained moisture to colonize, and Houston’s near-year-round cooling season means return air pulls damp air through the ducts almost continuously. Dallas systems get extended winter shutdowns; Houston systems don’t. The answer is climate, not equipment. If you suspect mold in your Lennox ductwork, call (469) 972-3151 and we’ll inspect it.
Yes, sweating registers are usually a sign of failed duct insulation, not just humidity. When the insulation degrades around a Lennox supply run, warm attic air reaches the cold duct surface and condenses. The interior of that same duct is likely wet, which means biological growth. We inspect the entire run, not just the register, and replace or reseal what’s failed.
We’re an independent service provider, not a Lennox authorized dealer, so we can’t speak to warranty terms. What we can tell you: we use OEM-spec materials and we don’t modify the air handler itself. Duct cleaning and sealing shouldn’t affect the equipment warranty, but confirm with Lennox or your installer if you have concerns. We’ll document exactly what we did.
We inspect the inner liner. If it’s intact but shedding surface fibers, we can seal and encapsulate it. If the board has absorbed moisture, lost structural rigidity, or shows mold penetration through the material, replacement is the honest call. In Houston’s older neighborhoods like Sharpstown and Westbury, we see both conditions in the same house. We’ll show you photos before we recommend either path.
Yes, because the contamination profile is different. Homes that flooded in Allison or Harvey often have silt lines and mold roots inside the duct board that standard cleaning won’t remove. We open sections of duct for inspection, not just the registers. If we find flood contamination, the cleaning approach changes from mechanical agitation to cut-and-replace of affected runs. Call (469) 972-3151 and we’ll tell you what your system actually needs.
