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 Trust CleanRun Air Duct Cleaning Pearland for Your Lennox Air Duct Cleaning?
We know Lennox-specific component layouts because we’ve pulled inspection cameras through them for years. The Signature series variable-speed air handlers with their ECM blower wheels. The Merit series coil cabinets with their compact return drops. The cased coils, the plenum geometries, the mastic joint patterns. Tomas Reyes, our owner, keeps a folded photo of his first inspection camera in his work bag - it stopped working in 2009, but it earned the right to stay. He grew up in Queens taking things apart to see how they worked, studied building systems technology at New York City College of Technology, then spent the better part of two decades running cameras through ductwork most homeowners never think twice about. His crew has logged jobs across Pearland and nearby areas, including Lennox service in Friendswood and older builds near Silverlake where flexible duct that should have been replaced years ago is still running, still moving dust through the house every time the system kicks on.
The camera goes in first. Then we talk. We use OEM-equivalent Lennox-compatible filters, mastic, foil tape, flex duct, and coil cleaners - the materials these systems actually need, since Lennox does not brand and sell duct-sealing consumables. Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman. Every technician is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. Our license number is published on this page, not buried in a footer. We publish it because a homeowner researching a high-ticket home service should be able to verify credentials without hunting.
Common Lennox Air Duct Cleaning Problems We Fix in Pearland
- Mastic and foil-tape seal failure on Signature series supply trunks. The SL280 and SLP98 air handlers in Pearland attics see plenum joints crack and pull away after years of 150°F summer heat cycling. Attic dust pulls straight into the airstream. We find this in Shadow Creek Ranch and Silverlake builds from the 2000s where the original mastic has gone brittle. Our crew reseals with fresh mastic and foil tape rated for the temperature swing, then photographs the joint before closing the attic access.
- Undersized filter grilles on Merit series return drops. The ML180, ML193, and ML296 systems often ship with filter grilles that bow the filter under static pressure. Bypass dust coats the evaporator coil and re-contaminates the supply side within weeks of any surface cleaning. We measure the free area, document the bow, and recommend grille upsizing or a filter cabinet retrofit when the numbers support it.
- ECM blower wheel loading on variable-speed air handlers. The SL280 and SLP98 ECM blower wheels collect drywall dust and pet hair after remodeling or heavy AC season - and Pearland’s 10-11 month cooling season means heavy is the default. A loaded wheel drops airflow, raises static, and makes the variable-speed logic work harder for less result. We remove, scrub, and balance the wheel as part of full system cleaning.
- Cased coil condensate pan sludge in CX34 and CH33 units. The pan collects biological film and standing condensate that re-contaminates ducts after cleaning if the coil pan is not part of the job. Pearland’s humidity averaging above 75% much of the year accelerates this. We clean the pan, treat the drain line, and photograph the pan condition before and after.
- Post-Harvey flood residue in Lennox systems throughout Pearland master-planned communities. Many homeowners replaced flooring and lower drywall after August 2017 but left original ductwork in place. We routinely pull returns in Shadow Creek Ranch and find flood-sediment residue, rust, and active mold colonies in systems that looked fine from the exterior registers. The camera shows what the grille hides.
BeforeAfterLennox Parts & Our Repair-vs-Replace Approach
Lennox does not sell branded duct-sealing consumables. We use OEM-equivalent mastic, foil tape, flex duct, and coil cleaners that meet or exceed the original specifications for the Signature, Elite, and Merit series. For filter replacements, we stock Lennox-compatible media in standard and custom sizes.
When a Lennox coil or air handler is leaking or rusted through, we tell the homeowner plainly whether cleaning and resealing will hold or whether replacement is the honest call. No upsell. We document the corrosion depth, the pan integrity, and the cabinet condition with photos, then write the scope and price before any work starts. Haven Standard Clause 1: written price before a single panel comes off. If you have another company’s written estimate, we offer a Free Second Opinion - our number next to theirs, both in writing. Call (346) 253-1822 to schedule.
Our Lennox Service Process - Step by Step
- 1

- 2
Written scope and price. Haven Standard Clause 1: the full scope, line-itemed, with a single flat price per system agreed before work starts. No per-vent pricing. No add-ons after the truck is on the drive.
- 3
Cleaning and repair. Negative-pressure extraction of the full supply and return system. Evaporator coil cleaning with pan treatment. Blower wheel removal and scrubbing for SL280 and SLP98 units. Duct sealing with mastic and foil tape at all accessible joints. Every step photographed.

FAQs - Lennox Air Duct Cleaning Service in Pearland
No. We are an independent Lennox service provider in Pearland, not affiliated with or authorized by Lennox International. We service Lennox equipment using OEM-equivalent parts and manufacturer-specified practices, but we do not represent the manufacturer. Our independence means we can recommend repair vs. replacement based on what the camera shows, not on brand incentives.
Yes. The SL280 and SLP98 ECM blower wheels are accessible through the blower compartment door on most cabinet configurations. We remove the wheel assembly, scrub it in a contained cleaning station, balance it, and reinstall. We photograph the wheel condition before removal and after cleaning. The static pressure drop across the air handler is measured before and after to verify the result. Call (346) 253-1822 to schedule.
It is a duct system problem originating at the return grille. The ML180, ML193, and ML296 systems often have filter grilles with insufficient free area; the filter bows under negative pressure, unseals at the edges, and lets bypass dust coat the evaporator coil. Cleaning the coil without fixing the grille solves nothing. We measure, document, and recommend grille upsizing or a filter cabinet when the numbers support it.
No, provided the cleaning is performed by qualified technicians using appropriate methods. Warranty coverage on the heat exchanger, compressor, and other sealed components is unaffected by duct cleaning. We do not open sealed refrigerant circuits or electrical enclosures without cause. Our documentation includes photos of all access points to demonstrate that no warranty-affected components were disturbed. If you have a specific warranty concern, bring your documentation and we will review it before starting work.
The most common cause in Pearland and surrounding areas like Manvel Lennox service territory is biological film in the cased coil condensate pan, combined with humidity-driven mold in the plenum or flex duct inner liner. The SL280 and SLP98 variable-speed air handlers run long cycles at low speed, which keeps the coil wet and extends the conditions for microbial growth. We clean the coil and pan, treat the drain line, and inspect the plenum and nearby ductwork with a camera. If flood residue from Harvey is present - common in Pearland homes that renovated surfaces but not ducts - we document it and include remediation in the scope. Call (346) 253-1822 for a camera inspection and written quote.
Yes. We reseal plenum joints with mastic and foil tape rated for attic temperature cycling, then pressure-test the seal where accessible. The original mastic on many Pearland Lennox installs has gone brittle after 15-25 years of 150°F summers. We photograph every joint before and after sealing. The work is included in our standard duct sealing scope or as a standalone repair, with a written price before we start.
Air Duct Cleaning services for whole-system Lennox in Pearland typically run $450-$850 for a single-system home, depending on duct run count, accessibility, and whether evaporator coil cleaning and blower wheel service are included.
