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.

Why Plano Residents Choose Us for Lennox Service
Tomas Reyes, our owner, grew up in the Bronx and learned the trade at Apex Technical School in Queens before spending close to two decades pulling, inspecting, and cleaning duct systems across North Texas. He and our crew have worked throughout Plano for years, including jobs in the older ranch-style homes near the Shops at Legacy where original flex duct from the early 1990s still surprises even experienced techs. Tomas built CleanRun around one habit: he photographs what’s inside the system before quoting a price, so the customer is looking at the same evidence he is. “Show the photo first. Talk second.”
That practice became the Haven Standard. Every job we do in Plano starts with a written price delivered before a single panel comes off, and ends with a Documented Photo Record of every duct run, included as standard. Our technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. We use professional-grade equipment from Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman, and we publish our license number on every page, not buried in a footer.
We are not a Lennox dealer or authorized service center. We are an independent provider with years of hands-on experience across Lennox’s full product range, and we source OEM or equivalent-quality aftermarket parts for repairs. Our Lennox sales & service page details our full equipment familiarity.
Common Lennox Air Duct Cleaning Problems We Solve in Plano

- Evaporator coil clogging in Merit and Elite systems. Plano attics exceed 140°F for months each summer, and when combined with the heavy cedar, ragweed, and grass pollen cycles of North Texas, Lennox coils in 13ACX, ML14XC1, and EL16XC1 units accumulate a sticky mat of dust, pollen, and degraded fiberglass fibers. We remove this buildup with controlled cleaning agents and document the before and after with photo evidence.
- Blower motor imbalance from attic dust ingestion. Lennox blower wheels and motors become coated with fine debris when return duct plenum connections loosen, a failure mode we see repeatedly in east Plano’s 1970s-1980s tract homes. The wheels run out of balance, bearings wear prematurely, and airflow drops before the homeowner notices warm spots in rooms.
- Static pressure faults in variable-speed Signature systems. Lennox Dave Lennox Signature Collection air handlers, including SL18XC1 and SL280V units, monitor system static pressure to modulate fan speed. When old flex duct collapses or duct board degrades in Plano’s extreme attic heat, resistance spikes and the control throws a fault code. Cleaning alone won’t fix this; we identify whether the ductwork needs repair or replacement.
- Heat exchanger corrosion in 1980s furnace installations. East Plano homes with original Lennox gas furnaces often draw humid spring air and attic insulation particles through corroded return ducts. Years of this exposure can accelerate heat exchanger deterioration. We inspect and document these conditions, and we will not clean a system we believe poses a safety concern.
- Disconnected flex-duct boots from slab movement. On the Blackland Prairie clay soils underlying much of east Plano, seasonal soil heave and shrinkage flex slab foundations enough to pull flex-duct boots loose from registers. Attic dust and insulation fibers bypass the filter entirely, entering living spaces through these separated joints. This is a Plano-specific failure mode we encounter far less in neighboring cities on sandier or rockier substrates.

AfterLennox Service in Plano: What Local Conditions Mean for Your Equipment
Plano’s explosive residential growth peaked in the late 1970s through the 1980s, leaving a dense concentration of east-Plano tract homes now sitting on 35-45-year-old fiberglass duct board and early flex-duct systems. These materials degrade and shed fibers under the extreme attic temperatures common here. Because HVAC systems in Plano run nearly continuously from May through September, those aging ducts accumulate allergens, dust, and degraded liner material faster than in cooler or newer markets.
For Lennox owners specifically, this means the evaporator coil, blower assembly, and return plenum are working in a harsher environment than the equipment was originally designed for. In east Plano’s Old Towne area, we inspected a 1982 brick-veneer home with a Lennox Elite EL16XC1 system and found flex-duct boots pulled loose from two bedroom registers due to slab movement on expansive clay soil. Our video inspection showed fiberglass particles and attic dust bypassing the filter and coating the evaporator coil; we cleaned the coil, resealed the plenum with mastic, and reattached the boots, restoring proper airflow and indoor air quality. This is the kind of Plano-specific diagnosis generic duct cleaning cannot provide.
The spring humidity followed by aggressive summer cooling also creates condensation conditions inside poorly insulated ducts, making mold colonization a recurring finding in our Plano service area inspections. We document this with photo evidence and explain what we found before quoting any remediation.
Lennox Models & Products We Service in Plano

We work across Lennox’s full residential range, including:
- Lennox Merit Series: 13ACX, ML14XC1, and related air handlers. Common in entry-level Plano installations from the 2000s; coils and blowers need regular attention in this climate.
- Lennox Elite Series: EL16XC1, EL18XCV, and matching indoor units. Variable-capacity components require precise static pressure management, which degraded ductwork undermines.
- Lennox Dave Lennox Signature Collection: SL18XC1, SL280V, and iComfort-enabled systems. Advanced controls flag faults that simpler systems ignore; we interpret these codes and trace them to root causes in the duct system.
- Lennox CompleteHeat and integrated systems: Combined heating and air handling units where duct integrity directly affects both comfort and safety.
We stock OEM and equivalent-quality aftermarket components for blower assemblies, coils, and control boards to maintain Plano turnaround times without waiting on factory shipments. When duct systems are degraded beyond sealing or cleaning, we recommend targeted replacement over repeated repairs, especially on 35-45-year-old fiberglass duct board. Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman tools, named so you can verify what we use before agreeing to a price.

FAQs - Lennox Air Duct Cleaning in Plano
Plano’s combination of 140°F+ attic temperatures, heavy North Texas pollen loads, and aging duct materials in 1970s-1980s housing stock creates more resistance and contamination than systems face in cooler or newer markets. The Blackland Prairie clay soils also cause slab movement that disconnects duct joints, bypassing filtration. Call (469) 452-7766 for a video inspection that will show you exactly what’s happening in your system.
Homes with original fiberglass duct board or early flex duct from the 1980s should be inspected every 2-3 years and cleaned when video inspection shows debris buildup exceeding manufacturer tolerance. The degraded liner material in these older systems does not behave like modern ductwork; it sheds fibers continuously under thermal stress. We provide the photo evidence so you can decide based on what is actually inside.
Lennox coils in Merit and Elite systems have closely spaced fins that trap the sticky mixture of pollen, dust, and fiberglass fibers common in Plano’s older homes. The extended cooling season here means this accumulation has more months to build each year. Our coil cleaning service removes this buildup without damaging the fin structure, and we photograph the result.
Yes. When flex-duct boots pull loose from registers due to slab movement on expansive clay, the system loses conditioned air into the attic and pulls unfiltered attic air into the return. The thermostat never satisfies, so the Lennox unit runs longer, increasing wear and energy use. We find this regularly in east Plano and correct it with boot reattachment, plenum sealing, and our Dryer Vent Cleaning in Plano when needed.
We use OEM or equivalent-quality aftermarket parts for Lennox blowers, coils, and controls, prioritizing exact-fit components to maintain performance and efficiency. We are an independent service provider, not a Lennox dealer, so we source from verified supply channels rather than factory-direct. Every part and its origin is documented in your job record.
