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 Richardson, TX | CleanRun Air Duct Cleaning Plano
Independent Lennox air duct cleaning in Richardson typically runs $380-$620 for a complete system, with most jobs scheduled within a week. What separates our Richardson work from standard duct cleaning is this: we’ve spent years inside the 1960s-1980s homes that dominate this city, and we know how Blackland Prairie clay slab movement has physically pulled apart the original ductwork that still feeds most Lennox systems here. Lennox sales & service from CleanRun means OEM-compatible parts, written pricing before any panel comes off, and a photo record of every duct run delivered when we leave. Call (469) 452-7766 for a free written estimate.
Why Richardson Residents Choose Us for Lennox Service
We’ve cleaned and repaired hundreds of Lennox-fed duct systems across the Dallas suburbs, from 1980s G-series furnaces still running in Canyon Creek to the variable-speed EL296V units installed in newer infill builds near US-75. That volume matters because Lennox equipment has specific airflow requirements. When a technician doesn’t know the difference between a Merit series return specification and a Dave Lennox Signature Collection static pressure rating, they guess at duct sealing and often create more restriction than they remove.
Tomas Reyes, our owner, started this company in 2013 after close to two decades pulling, inspecting, and cleaning residential duct systems across North Texas. He grew up in the Bronx, trained at Apex Technical School in Queens, and built CleanRun around a habit he still enforces on every Richardson job: photograph what’s inside the system before quoting a price. “Show the photo first. Talk second.” That means when we arrive at your Richardson home, we’re not selling a package. We’re showing you the 3-inch debris build-up at the first elbow, the cracked mastic at the plenum connection, or the separated boot under your hallway register. Then we put a written price in front of you, and only then does work begin.
Every crew that Richardson service area customers meet operates under the H.A.V.E.N. Standard. Haven Standard Clause 1: written price before any work starts, every time. Haven Standard Clause 3: Verified Crews, background-checked and uniformed, identified by name before arrival. The 365-Day Done Right Promise backs every job in writing, not as a policy subject to manager approval. And our equipment roster, Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman, is named here so you can verify what we’re running before you agree to anything.
Common Lennox Air Duct Cleaning Problems We Solve in Richardson
- Variable-speed air handler overload on undersized returns. Lennox units like the CBX32MV produce higher static pressure than the single-speed furnaces they replace. In Richardson’s 1960s-80s homes, original return trunks were sized for 3-4 ton single-stage units. The mismatch accelerates dust pull-through and erodes fiberglass duct liner. We measure static pressure with a manometer, then clean and seal or recommend return trunk upsizing.
- Cracked mastic at original plenum connections. Lennox plenums and transition collars from the 1980s and 90s were sealed with mastic that dries and cracks over 30-40 years. Richardson’s Blackland Prairie clay expands and contracts with moisture, shifting slabs and opening gaps at the furnace connection. We remove failed mastic and reseal with OEM-compatible compounds rated for Lennox system airflow temperatures.
- Evaporator coil biological growth in continuous-run seasons. Richardson’s AC runs nearly continuously from May through late September. Lennox evaporator coils stay wet for months, promoting growth that sloughs into the supply trunk. We clean the coil face and treat it during duct service, or the ducts recontaminate within weeks.
- Closet return air leakage on G-series furnaces. Older Lennox G-series units commonly share a closet or platform with the return duct. When the cabinet seal degrades, the blower pulls unfiltered closet air coated with Richardson’s mountain cedar, elm, and ragweed pollen. We source OEM-style gaskets for Lennox air handler cabinets and verify seal integrity with smoke pencil testing.
- Separated flex duct boots from slab movement. The expansive clay beneath Canyon Creek and similar subdivisions pulls flex duct boots loose from floor registers. The gap hides under carpet. A Lennox system can pull attic insulation fibers and ground-level debris into living areas for years. Our video inspection catches this before cleaning begins.
BeforeAfterLennox Service in Richardson: What Local Conditions Mean for Your Equipment
Here’s the connection no generic page makes. Richardson’s residential core was built primarily between 1960 and 1985. Neighborhoods like Canyon Creek and those flanking US-75 still contain original or first-generation fiberglass-lined metal ductwork that is now 40-60+ years old. Critically, the Blackland Prairie expansive clay soil beneath virtually all of Richardson causes chronic slab heave and settlement, which physically shifts and gaps duct connections over time, pulling in unconditioned air and ground-level contaminants. This failure mode is far more prevalent here than in newer-slab suburbs like Frisco or Allen.
For Lennox owners specifically, this creates a hidden problem. A homeowner installs a 2005 Lennox G61V furnace, or a 2018 EL296V, and assumes the “new” system means clean air. But the trunk lines, plenums, and flex runs are original 1972 or 1983 construction. The new Lennox variable-speed blower, with its higher static pressure and longer run cycles, actually worsens the infiltration through those gapped connections. We’ve found this exact scenario repeatedly in Richardson’s established neighborhoods: the equipment is modern, the ductwork is failing silently, and the homeowner is changing filters monthly wondering why the furniture still dusts over in two days.
In Canyon Creek, a homeowner with a 2005 Lennox G61V furnace and original 1972 ductwork called us because of heavy dust on furniture despite regular filter changes. Our video inspection found the return boot at a hallway floor register had separated from the trunk by nearly an inch due to slab settlement. We sealed the boot with mastic, reattached the flex run, and cleaned the full return and supply system. The dust complaint stopped immediately. The homeowner had lived with that gap for eight years.
Lennox Models & Products We Service in Richardson
We work on the full Lennox residential line, including the Elite series (EL296V, EL18XPV), Merit series (ML14XC1, ML193UH), Dave Lennox Signature Collection (SL28XCV, SLP98V), and older Complete Heat and G-series furnaces common in 1980s-90s Richardson homes. Our parts approach is specific: OEM-equivalent aftermarket flex duct, mastic, and boot collars matched to Lennox airflow requirements, plus OEM-style gaskets for air handler cabinet sealing when original Lennix components are obsolete or back-ordered.
For Richardson customers, we stock common Lennox transition collars and boot sizes locally. Most repairs don’t wait on shipping. If your Lennox equipment is 15+ years old and the duct system is failing at multiple points, we’ll tell you honestly whether targeted repairs or full duct replacement makes better long-term sense. No urgency. No coupon bait. Just the photo record and a written number.
Lennox Service Pricing in Richardson
Whole-system Air Duct Cleaning in Richardson runs $380-$620 for a typical single-system home. What moves the price: square footage of duct run, number of supply and return registers, whether the evaporator coil requires cleaning, and the condition of original ductwork (separated boots, failed mastic, or collapsed flex add repair time). Dryer vent cleaning bundled with duct service adds $120-$180.
Every estimate includes video inspection of the trunk and main branches, written scope of work, and the documented photo record delivered as a standard job file. We do not quote per-vent pricing. Haven Standard Clause 1: one flat price per system, agreed in writing before work starts. No add-ons once the truck is in your driveway.
Call (469) 452-7766 for a free written estimate. We’ll schedule a technician to inspect your Lennox system, show you what’s inside the ductwork, and put a flat price in writing before you decide.

FAQs - Lennox Air Duct Cleaning in Richardson
Yes. The furnace age and duct age are independent. A 2005 Lennox blower pushes air through 50-year-old fiberglass-lined metal or early flex duct that has accumulated decades of debris, and Richardson’s heavy pollen load accelerates buildup. We inspect first, photograph what we find, and quote cleaning or repair based on actual condition. Call (469) 452-7766 to schedule a free inspection.
Richardson’s older slab construction on Blackland Prairie clay creates more duct leakage than Frisco’s newer, more stable foundations. Gaps at plenum connections and separated boots pull unfiltered attic and crawl-space air. Combined with DFW’s severe allergy burden, your Lennox blower is working harder and pulling more infiltration. We locate and seal the leaks, then clean the system. Call (469) 452-7766 for a written estimate.
Not when done correctly. We use negative-pressure extraction with controlled brush agitation, not aggressive mechanical scraping. For deteriorated liner, we note it in the video inspection and recommend repair or liner replacement before full cleaning. The photo record shows you exactly what we found and what we did. Call (469) 452-7766 to discuss your specific duct construction.
Every 2-3 years for Richardson’s continuous-run climate. May through September wet-coil conditions promote biological growth that sloughs into supply ducts. Cleaning the ducts without addressing the coil wastes the customer’s money. We include coil inspection in every duct cleaning estimate and recommend cleaning when growth is visible. Call (469) 452-7766 to schedule.
Often yes. New Lennox variable-speed units produce higher static pressure than the equipment they replace, which worsens leakage through existing gaps. Sealing first lets the new system perform to specification. We evaluate whether partial sealing, full sealing, or duct replacement pairs best with your planned equipment upgrade. Call (469) 452-7766 for a free second opinion on any written estimate you’ve already received.
