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 Dallas, NY | CleanRun Air Duct Cleaning
Air Duct Cleaning in Dallas for Lennox systems costs between $380 and $690 for a full system, and the reason that number varies is what we find once a camera goes inside the attic runs. We’re an independent Lennox service provider serving Dallas homeowners with a different approach: every job starts with a written price, every duct run gets photographed before and after, and every repair is backed by our 365-Day Done Right Promise. Because Dallas homes sit on expansive clay and run every Lennox system’s ductwork through attics, the cleaning work here often becomes repair work, and that’s the part most companies skip. Call (806) 606-6902 for a written estimate that tells you exactly what’s in your ducts before a single panel comes off.
Why Dallas Residents Choose Us for Lennox Service
We’ve worked on Lennox systems in Dallas long enough to know what a slab-shifted flex run looks like and what a 140°F attic does to a plastic drain pan. Tomas Reyes, our owner and lead technician, grew up in a Queens building where the ductwork hadn’t been cleaned since the Carter administration, and he’s spent his entire career since making sure no Dallas homeowner has to wonder what they’re breathing. He completed his HVAC coursework at Queensborough Community College before moving into residential and commercial duct systems, including our HVAC Cleaning in Dallas, and the approach hasn’t changed: camera inspection first, written scope second, and no work until the customer sees the photo. The photo tells you what’s in there. Everything else is just paperwork.
We’re not a factory-authorized Lennox dealer, and we’ll tell you that up front. What we offer is daily familiarity with Lennox equipment across Dallas: Elite, Merit, and Signature systems all show up on our schedule. We stock the aftermarket parts that make sense in this market, use genuine Lennox components when they’re cost-effective and available, and never push a replacement when a repair is the honest answer. Every crew arrives background-checked, uniformed, and operating under the H.A.V.E.N. Standard. The Lennox sales & service route is fine for new equipment quotes, but when your system is pulling attic air through separated joints, you want someone who opens the plenum with a camera, not a brochure.
Common Lennox Air Duct Cleaning Problems We Solve in Dallas
- Kinked and collapsed flex runs: Dallas clay swells and shrinks all year, and slab movement tugs attic flex duct taut. We open attics in Lake Highlands and Oak Cliff every summer and find 8-inch supply lines collapsed to half their diameter because the slab heaved and the flex had no slack left. That’s not a cleaning problem; it’s a repair problem disguised as weak airflow.
- Coated evaporator coils on Lennox Elite and Signature systems: The cased A-coils in EL296V and XC20 systems trap Dallas pollen, ragweed, and drywall dust, then seal under a hard, waxy layer. Head pressure climbs, the coil freezes, and the system shuts down on a 95°F day. Cleaning an evaporator coil in Dallas should be a preventative step, not an emergency.
- Cracked plastic drain pans on 1980s-era Lennox air handlers: Thermal cycling in an unconditioned attic is brutal on plastic. We see cracked corners leaking condensate onto insulation, which grows mold and pulls biological particles into the return. Dallas ranch homes from the 1960s to 1980s are the prime candidates.
- Dust-caked variable-speed blower modules: Lennox variable-speed blowers pack attic lint and drywall dust into the cooling fins of the module itself. In Dallas, where the AC runs almost continuously from April through October, those modules throw overheat codes and shut down intermittently, which confuses homeowners and drains efficiency.
- Separated trunk-to-plenum connections: The Eagle Ford Shale under Dallas expands over 30% more than average Texas clay when wet. Duct systems sealed perfectly in October can be pulling an inch apart by March. That separation draws attic insulation, rodent dander, and construction dust straight into the conditioned space.
BeforeAfterLennox Service in Dallas: What Local Conditions Mean for Your Equipment
Dallas sits on some of the most expansive black clay soils in North America, and because nearly every home here is slab-on-grade with no basement, all Lennox ductwork runs through the attic. Those two facts combine into something you don’t see in cities with basements or stable soil: every seasonal moisture swing pulls on flex-duct connections and rigid-trunk joints, and the attic air waiting to enter those gaps is loaded with insulation fibers, rodent dander, and construction dust from a metro that never stops building. In East Dallas and Oak Cliff, our crews routinely find duct joints that separated over the winter and kinked flex runs installed with too little slack; we carry extra flex and mastic on every Dallas job without being asked. A Lennox cleaning here that doesn’t include a joint-integrity check is just a vacuum pass. Last August we opened the attic of a Lennox XC20 on Ferndale Drive in Lake Highlands and found the main trunk had pulled a full inch from the plenum, while the 10-inch flex to the master bedroom had kinked flat against a roof brace. Our tech rebuilt the connection, re-slacked and re-hung the flex, then sealed every joint; head pressure dropped 18 PSI that afternoon and the master finally held set point.
Lennox Models & Products We Service in Dallas
We service the full Lennox residential range across Dallas service area: the Elite Series (EL296V, EL18XCV), Merit Series (ML14XC1, ML180), Signature Collection (XC20, SLP99V), and Dave Lennox Signature Collection (SL280, XC21). Our parts approach is straightforward: genuine Lennox blower modules, control boards, and coils go in when they’re available and fairly priced, but we won’t hold a Dallas family hostage to an inflated OEM flex duct price in July. Quality aftermarket flex, mastic, and media filters are part of the honest repair trade, and we’ll tell you which one we’re installing and why. If your Lennox air handler is 18 years old and the coil has its third leak, we’ll say that clearly. We won’t sell a $1,400 coil job on a unit that should be retired.

FAQs - Lennox Air Duct Cleaning in Dallas
Because Dallas slab movement constantly tugs attic flex runs out of shape, which means the air you’re paying to cool is leaking or pulling attic particulates into the home. A vacuum pass cleans the inside of the duct but does nothing about a kinked 8-inch line or a separated trunk joint. We include a joint-integrity check and flex repair evaluation with every cleaning in Dallas because skipping it leaves the real problem in place. Call (806) 606-6902 and we’ll put the pricing in writing before anything gets touched.
Dallas attics routinely exceed 140°F in summer, and that cooks the pollen, dust, and biological material that lands on your Lennox coil into a hard, waxy layer. Once that layer forms, airflow drops and the coil can freeze. We recommend coil inspection with every annual cleaning in Dallas, with actual cleaning when buildup is visible. The spring season after juniper and oak pollen is the smart time to check. Call (806) 606-6902 to schedule a coil inspection before the next heat wave.
Yes. Fiberglass duct board in 1960s to 1980s Dallas ranch homes gets brittle after decades of attic heat, and the constant flexing from slab heave cracks it at the joints. Those cracks pull attic air and fiberglass particles directly into the airstream. We photograph every cracked section and quote a sealing or replacement price before starting work. Call (806) 606-6902 and ask about our documented photo record; you’ll see exactly what your duct board looks like inside.
In Dallas, the most common cause is a dust-caked blower module. Variable-speed motors pull air across their own electronics for cooling, and attic lint, drywall dust, and insulation fibers pack into the cooling fins, triggering overheat codes and intermittent shutdowns. Cleaning the module and restoring airflow is often the fix. We include blower inspection with full-system duct cleaning, and if the module itself has failed, we’ll quote a genuine Lennox replacement. Call (806) 606-6902 to get your unit looked at before the next 100°F day.
Cleaning removes the accumulated pollen reservoirs that recirculate every time your Lennox system runs, and in Dallas, where juniper hits in winter, oak and elm in spring, and ragweed in fall, those reservoirs are significant. What cleaning can’t do is stop fresh pollen from entering the home when doors and windows open. What it can do is stop your system from acting as a pollen bank during the long April-to-October run season. If allergies are the concern, ask about our sanitizing option and media filtration when you call (806) 606-6902.
