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.

AfterWhy Fort Worth Homeowners Choose Lennox Air Duct Cleaning
CleanRun Duct Repair & Cleaning provides independent Lennox service in Fort Worth, TX - not authorized by Lennox, but staffed by technicians who have worked on Dave Lennox Signature Collection, Elite Series, and Merit Series systems across this city since 2013. Our Lennox work is distinguished by one practice: we video-scope every duct run and photograph the inside before quoting a written price, so the scope you approve matches what the camera actually found.
Fort Worth’s housing stock creates a unique concentration of Air Duct Cleaning services demand for Lennox duct problems you won’t see clustered this way in Dallas. The postwar brick ranches of Wedgwood, Ridglea Hills, and Polytechnic Heights - built 1950s through 1970s - often contain original joist-panned returns with gasketed chases that have dried out and separated, pulling Cross Timbers dust straight into the blower. Meanwhile, the rapid-build subdivisions of Alliance, Saginaw, and Haslet from the 1990s and 2000s are packed with flex-duct Lennox systems that have spent twenty-plus years in attics hitting 150°F, sagging at plenum takeoffs and crushing airflow to back bedrooms. We have documented both patterns hundreds of times. Call (817) 520-8797 for a free estimate.
Why Trust CleanRun Air Duct Cleaning Fort Worth for Your Lennox Air Duct Cleaning?
Tomas Reyes, our owner, grew up in the Bronx and learned his first trade skills at Bronx Community College before spending years in the field learning exactly what accumulates inside residential duct systems when nobody’s paying attention. He and our crew have run Lennox jobs across Fort Worth for years, including extensive work in the Near Southside where older homes hold onto decades of debris in ways newer builds don’t. Tomas is known for pulling the camera out before saying a word about scope or price. The camera doesn’t have a sales pitch. If the footage doesn’t show a problem, he’ll tell you that too.
Our technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. We carry genuine Lennox-compatible filters and cabinet hardware where fit matters, and we use professional-grade equipment from Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - brands you can look up independently before agreeing to any price. Every job concludes with a Documented Photo Record of every duct run, included as standard. The 365-Day Done Right Promise applies to Lennox work exactly as it does to every other system we touch: if it’s not done right, we make it right, backed in writing on every job.
Common Lennox Air Duct Cleaning Problems We Fix in Fort Worth
- Joist-panned return chases leaking at seams on older Lennox furnace installs. In Fort Worth neighborhoods like Polytechnic Heights and the historic North Side near the Stockyards, we regularly encounter 1940s through 1960s homes where the original cloth-backed duct tape on galvanized sheet-metal joints has fully disintegrated. The gasketed chase lid under the air handler separates, pulling attic insulation and fine Blackland Prairie dust directly into the blower compartment. We rebuild these chases with new gasketing and mastic, then clean the coil and blower assembly so the system isn’t recirculating fiberglass and grit.
- Ductboard runouts collapsing at the plenum takeoff on Signature and Elite variable-capacity units. Lennox’s higher-end variable-capacity systems are sensitive to static pressure. When ductboard runouts soften from years in a 140°F Fort Worth attic and collapse at the takeoff, airflow drops and the blower ramps up to compensate. We replace collapsed sections with properly sized flex duct or sheet metal, seal with mastic, and verify static pressure before leaving.
- Excess mastic cracking at the air handler cabinet door. During original install, some Lennox air handlers received thick mastic beads at the cabinet access door that looked sealed but cured brittle. After five to ten Fort Worth summers, the mastic cracks and introduces lint, construction dust, and attic debris into the evaporator coil. We remove the failed mastic, clean the coil with foaming cleaner and low-pressure rinse, and reseal with flexible, UV-stable mastic rated for attic exposure.
- Supply boots separating from register cans in flex-duct Lennox systems. In Alliance and north Tarrant County production homes from the 1990s and 2000s, the supply boot connection to the register can drops away, dumping conditioned air into the wall cavity and starving the room. The blower works harder, energy bills climb, and rooms stay hot. We reattach with mechanical fasteners and mastic seal, then verify airflow at the register with a digital anemometer.
- Evaporator coil fouling from return-side debris intrusion. Whether from a failed chase gasket, cracked cabinet mastic, or disconnected return duct, debris that bypasses the filter coats the Lennox evaporator coil. The coil freezes, airflow drops, and the compressor strains. Our Evaporator Coil Cleaning service removes the fouling chemically and mechanically, then we fix the intrusion point so it doesn’t recur.
BeforeAfterLennox Parts & Our Repair-vs-Replace Approach
We use genuine Lennox-compatible filters and cabinet hardware where dimensional fit and airflow rating matter. For flex duct, mastic, register boots, and sealant, we use quality aftermarket parts that meet or exceed Lennox specifications - no need to overpay for brand-marked sheet metal and tape. Our trucks stock Rotobrush and Nikro negative-pressure extraction equipment, Abatement Technologies HEPA filtration, and Guardsman coil cleaner for same-day resolution of most Lennox duct and coil issues in Fort Worth.
If we find a cracked heat exchanger in an older Lennox furnace, we say so plainly and compare the repair cost against replacement. Haven Standard Clause 1 requires a written price before any work starts, so you’ll see both numbers in writing before deciding. Same for a collapsed ductboard plenum on a Signature system: we’ll quote rebuild and replacement options, document the damage with photos, and let the footage guide your choice. Call (817) 520-8797 and we’ll put our number next to any competitor’s written estimate - free second opinion, no obligation.

Warranty documentation delivered. The 365-Day Done Right Promise is printed on your invoice, along with the photo record and the technician’s notes. If something isn’t right, we make it right.
Lennox Products We Service & Install in Fort Worth
We service and clean ductwork connected to Lennox Dave Lennox Signature Collection variable-capacity systems, Elite Series two-stage and single-stage equipment, Merit Series entry-level systems, and legacy 13ACX and 14ACX air conditioners still running in Fort Worth homes. Our trucks carry filters and cabinet hardware compatible with these lines, and we maintain coil cleaning equipment sized for the narrower evaporator cabinets common in Merit Series air handlers. For duct repairs and replacements, we stock flex duct, sheet metal, and register boots in standard Lennox sizes. We do not sell new Lennox equipment - we are an independent service provider - but we coordinate with local HVAC contractors when a Signature or Elite system replacement is the honest recommendation.
We Also Service These Brands
Our technicians are equally familiar with Trane and Carrier duct configurations, and we regularly clean and repair mixed-brand systems in Fort Worth homes where the furnace and condenser were replaced at different times. The Haven Standard, our documented photo record, and our 365-Day Done Right Promise apply to every brand we touch.
FAQs - Lennox Air Duct Cleaning Service in Fort Worth
No. We are an independent Lennox service provider - not affiliated with or authorized by Lennox Industries. We service Lennox equipment based on hands-on experience with their ducted systems across Fort Worth, not on manufacturer training or scripting. Our recommendations come from what the camera and test instruments show, not from a brand manual.
Sometimes. Short cycling in a Signature variable-capacity unit often traces to high static pressure from collapsed ductboard, restricted return airflow from a separated chase gasket, or a fouled evaporator coil raising head pressure. We scope the system, measure static pressure, and show you the cause before quoting repair. If the ductwork is clear and pressures are normal, we’ll tell you the problem is elsewhere and recommend an HVAC technician who handles refrigerant and controls. Call (817) 520-8797 for a free estimate.
Frequently yes. A frozen coil in a Lennox system usually means insufficient airflow across the evaporator, and the ductwork is often the culprit: collapsed return duct, separated supply boot, or blower compartment fouled with attic debris. We clean the coil, find the airflow restriction, and fix it. If the coil freezes again after our work, the 365-Day Done Right Promise covers our return at no charge.
We carry Lennox-compatible filters, cabinet hardware, and coil pans that match common Fort Worth inventory. For obsolete Signature or Elite Series components, we source through regional HVAC suppliers and can typically have parts within 24 to 48 hours. We do not markup parts - you see our cost plus labor on the written quote before work starts.
Yes, and we do it regularly in Lennox Air Duct Cleaning in Lake Worth, TX and Fort Worth’s older neighborhoods. Joist-panned returns require careful handling - aggressive brushing can dislodge decades-old debris into the blower. We use controlled negative-pressure extraction with HEPA containment, inspect the panning seams with a camera first, and repair any separation before pressurizing the system. The Near Southside and Polytechnic Heights are full of these systems; we’ve documented hundreds.
For most Fort Worth homes, every four to six years is sufficient, though homes near active construction, with pets, or in the dustier western Cross Timbers exposure may need it sooner. The real indicator is what the camera shows. We have cleaned Lennox systems in Ridglea Hills that were fine at eight years, and Alliance homes that needed it at three due to construction debris left in the ducts during original build. Call (817) 520-8797 and we’ll scope it - estimates are free.
