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 Allen, TX | CleanRun Air Duct Cleaning Plano
Air Duct Cleaning in Allen for Lennox systems typically runs $380-$620 for a complete multi-zone system, with most jobs completed in a single visit. CleanRun is an independent Lennox service provider, not manufacturer-authorized, and we’ve spent twelve years documenting what actually happens inside Allen’s aging flex duct systems. Call (469) 452-7766 for a written price before any work starts.
Why Allen Residents Choose Us for Lennox Service
We know Lennox equipment because we’ve pulled it apart in Allen attics since 2013. Tomas Reyes, our owner, started with trade fundamentals at Apex Technical School in Queens and has logged close to two decades inspecting residential duct systems across North Texas. His habit is simple: photograph what’s inside before quoting a price. “Show the photo first. Talk second.” That habit became the CleanRun standard.
Our crews carry OEM Lennox blower motors and coil assemblies for the Merit, Elite, and Dave Lennox Signature lines, plus aftermarket flex duct and mastic that meets or exceeds original specs for the repair work. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We serve the Allen service area from our Plano base, and we’ve worked the subdivisions enough to know which attic configurations hide the worst sag points.
Our Lennox sales & service approach is straightforward: written price before work starts, documented photo record of every duct run delivered when we leave, and the 365-Day Done Right Promise in writing on every job. No exceptions. No manager approval required.
Common Lennox Air Duct Cleaning Problems We Solve in Allen
- Sagging flex duct low points trap debris. Allen’s 1990-2010 two-story homes run Lennox flex duct across unusually long attic spans. After 15-25 years of 130-140°F summer heat cycling, second-floor runs sag at predictable low points. Fine Collin County clay dust and condensate collect there, forming compacted plugs that standard filter changes never reach. We target these sag points during cleaning, not just the main trunk.
- Thermal stress breaches duct liner. North Texas attic temperatures accelerate micro-tears in Lennox flex duct walls. Debris embeds in those tears and bypasses filter capture entirely. Our video inspection finds the breach locations before we quote repair versus cleaning.
- Evaporator coil fouling from long cooling seasons. Lennox air handlers in Allen attics run almost continuously for five to six months. The CBA27 and CBX32M coils we see collect biological growth and dust that restricts airflow across the fins. We clean the coil assembly with the ductwork, not as an afterthought.
- Return-air chase leakage pulls in unfiltered attic air. Lennox return chases in Allen’s large two-story homes leak at mastic joints and boot connections. That pulls pollen, clay dust, and 140°F attic air straight onto the blower and secondary heat exchanger. We seal what we find and photograph the before and after.
- Multi-zone airflow imbalance. Lennox systems in 3,500 sq ft Watters Crossing homes often show one zone starved while another over-performs. The cause is usually a combination of sag-point blockages and leaky returns. We map the pressure differentials with manometers, fix what the numbers show, and give you the readings.
BeforeAfterLennox Service in Allen: What Local Conditions Mean for Your Equipment
Allen’s explosive residential growth between 1990 and 2010 created something you won’t find in older Plano or newer Frisco: a dense, homogeneous stock of large two-story tract homes whose original attic-installed flex duct systems are now 15-25 years old. In Twin Creeks, Watters Crossing, and the neighborhoods off Exchange Parkway, these homes were built with multi-zone Lennox systems fed by flex duct runs that are simply longer than what rigid duct systems in older areas require. More length means more low points. More low points mean more places where Collin County clay dust and spring pollen settle into condensate, harden, and quietly choke second-floor airflow.
We see this pattern repeat. The homeowner notices the upstairs bedroom never cools properly. The Lennox EL16XC1 or ML14XC1 runs longer, works harder, and the utility bill climbs. A standard filter change doesn’t help because the blockage is ten feet down a sagging flex duct run, past the register, in a 140°F attic where no homeowner is going to crawl. That’s the Allen-specific failure mode we built our cleaning protocol around. We don’t just vacuum the accessible trunk line. We run the camera through every branch, identify the sag points, and clean or repair what we find, including our Dryer Vent Cleaning in Allen if needed.

We clean and repair air distribution components across the full Lennox residential line. That includes Merit Series systems like the 13ACX, 14ACX, and ML14XC1; Elite Series units including the EL16XC1 and variable-capacity EL18XCV; and Dave Lennox Signature Collection equipment such as the SL18XC1 and SL25XPV.

Lennox Service Pricing in Allen
Complete Lennox air duct cleaning for a typical Allen two-story home runs $380-$620 for the full system. This covers all duct runs, registers, the plenum (the main distribution box), and the evaporator coil on attic-installed air handlers. Flex duct repair at identified sag points adds $180-$340 per section, including re-routing with proper slope and sealed connections. Video inspection is included in every quote.
What drives the cost: square footage, number of zones, accessibility of attic runs, and whether we find compacted debris plugs requiring mechanical agitation rather than vacuum extraction. We deliver a written price before any work starts, every time, under Haven Standard Clause 1. No per-vent pricing. No $79 coupon that becomes something else once the truck is in your driveway.

FAQs - Lennox Air Duct Cleaning in Allen
The most reliable indicator is uneven cooling between floors, especially upstairs bedrooms that never reach set temperature even when the Lennox system runs continuously. In Allen’s 1990-2010 subdivisions, we find sag points in roughly 70% of second-floor flex duct runs over 15 years old. Our video inspection shows you the exact location and debris load before we quote any work. Call (469) 452-7766 to schedule a camera look.
Yes. We remove and clean the coil assembly on Lennox CBA27, CBX27, and CBX32M air handlers as part of our standard duct cleaning scope, or as a standalone service if the ductwork is clear but coil fouling is restricting airflow. Allen’s long cooling season and high attic humidity make this a common need. The coil is photographed before and after, and the cleaning is documented in your job record.
We lean toward repair when the ductwork can be restored to proper function and the Lennox air handler or condenser still operates within manufacturer efficiency ranges. In Allen, we often see 20-year-old Lennox Merit and Elite systems with failed flex duct but solid mechanical components. We give an honest assessment with pressure readings and photo evidence. If replacement makes more sense, we’ll say so and explain why. Call (469) 452-7766 for a written evaluation.
Collin County’s cedar, elm, and oak pollen loads visibly coat filter media within weeks during peak season. When Lennox return-air chases leak at mastic joints, that pollen bypasses the filter entirely and accumulates on the blower wheel and in the ductwork. We see this in nearly every two-story home we inspect in Allen. Sealing the returns and cleaning the system before peak season starts in late February reduces the load significantly.
We use OEM Lennox parts for critical mechanical components like blower motors and coil assemblies. For flex duct, mastic, and fittings, we use quality aftermarket products that meet or exceed original specifications. We name our suppliers on request, and every part is documented in your job record. The 365-Day Done Right Promise covers all work regardless of part source.
