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 Atlanta Homeowners Choose Lennox Air Duct Cleaning
CleanRun provides Air Duct Cleaning services, repair, and sealing for independent Lennox systems across metro Atlanta for ELITE, MERIT, SIGNATURE, and legacy G-series systems. We track Lennox-specific airflow and static-pressure specs, stock OEM-compatible parts for communicating controls and variable-speed blowers, and deliver a written flat price before any work starts - typically $249 to $399 for a complete system cleaning depending on ductwork size and accessibility.
We’re not affiliated with or authorized by Lennox. We’re an independent Atlanta Lennox service provider that has spent years tracing how these systems behave in the city’s actual housing stock - from 1920s Grant Park bungalows with retrofitted flex duct to newer builds in Buckhead running ELITE variable-speed furnaces. Our crew knows the difference between a standard brush pass and what a Lennox high-static ECM blower actually demands from its ductwork. Every job includes a Documented Photo Record of every duct run, delivered before we leave.

Why Trust CleanRun Air Duct Cleaning Atlanta for Your Lennox Air Duct Cleaning?
Tomas Reyes, our owner, grew up in the Bronx and picked up his trade fundamentals at Bronx Community College before spending the better part of two decades pulling duct work on both sides of the Mason-Dixon line. He and our crew have been running jobs across Atlanta for years, including Lennox repair in Decatur and plenty of older split-level homes near Cascade Heights where the flex duct runs long and the debris tells a clear story about how many filters got skipped. Tomas is known for showing customers the before-and-after camera footage without being asked, and for quoting a flat price before a single tool comes off the truck.
That matters for Lennox owners because these systems are engineered tight. The ELITE Series SL280V and EL296V variable-speed furnaces use high-static ECM blowers that pull markedly harder than standard PSC motors. When return ducts are undersized or flex runs are partially collapsed - common in Atlanta’s retrofitted bungalows - those blowers will literally pull attic insulation into the return stream. We’ve found fiberglass packed around blower wheels that the homeowner never knew was there. The camera doesn’t negotiate.
Our technicians carry Lennox airflow specs on every job and stock OEM-compatible parts for communicating controls, blower assemblies, and heat exchangers. For standard flex duct, mastic, and registers we use high-quality aftermarket that meets or exceeds manufacturer spec. Every repair is warranty-safe and documented in writing under Haven Standard Clause 1: Written Price Before Work Starts.
Common Lennox Air Duct Cleaning Problems We Fix in Atlanta
- Collapsed flex return trunks on ELITE variable-speed systems. The ECM blower in a Lennox EL296V or SL280V ramps up to maintain airflow against restriction. In Atlanta’s intown neighborhoods, we regularly find 16-inch flex returns installed in the 1980s or 1990s that have sagged under decades of Georgia humidity, collapsing to 40-60% of their design diameter. The blower compensates by pulling harder, which draws attic air through any seam or collar leak. We replace the crushed run, seal with mastic, and re-balance static pressure.
- iComfort misreporting masking duct leakage on SIGNATURE systems. The Lennox SIGNATURE Series SL297NV and XC25 use proprietary iComfort Wi-Fi communicating thermostats and control boards. These systems can misreport actual blower RPM, which means a homeowner sees “System Malfunction” or erratic temperature control while the real problem is a leaking return plenum or disconnected flex joint. Our video inspection catches what the control board can’t see.
- Condensate pan cracks and coil fin fouling in MERIT and ELITE air handlers. Atlanta’s humid subtropical climate keeps relative humidity above 60% through most of spring, summer, and fall. Lennox evaporator coils in ML180, ML193, and ELITE-series air handlers develop microbial growth on fin surfaces and stress cracks in condensate pans. That biological load blows straight into the ductwork. We clean the coil and pan as part of full system cleaning, then photograph the before and after.
- Heat-cracked collars and back-drafting on legacy G-series furnaces. Older Lennox G-series units still running in Decatur, Candler Park, and Virginia-Highland bungalows commonly develop cracked flexible duct connectors at the furnace collar. The back-draft pulls dust and combustion byproducts into the supply trunk. We replace the collar, inspect the heat exchanger, and clean the supply runs that were contaminated.
- Attic infiltration from degraded flex insulation. Atlanta attic temperatures routinely exceed 130-140°F in summer. That heat degrades the insulation on flex duct routed through unconditioned attic spaces, causing seams and tape to fail. Particulate-laden attic air infiltrates supply lines, and the homeowner notices dust reappearing within days of changing filters. We seal with mastic and replace degraded sections, not just tape over them.
BeforeAfterLennox Parts & Our Repair-vs-Replace Approach
We use genuine Lennox OEM parts for communicating controls, blower motors, and heat exchangers - these components interact with proprietary iComfort protocols and variable-speed algorithms that aftermarket equivalents rarely replicate correctly. For standard flex duct, mastic, collars, and registers we source high-quality aftermarket from Guardsman and Abatement Technologies that meets or exceeds Lennox airflow spec.
Our repair-vs-replace call is straightforward. If your 15-year-old Lennox air handler needs an $1,800 evaporator coil and a $900 blower motor, we’ll tell you that duct sealing won’t save it. Haven Standard Clause 1 requires a written price before work starts, and that price includes every option - repair, replace, or defer - with the numbers attached. No manager approval needed. Call (470) 495-9370 for a written second opinion on any competitor’s estimate.
Our Lennox Service Process - Step by Step
- 1
Diagnosis with video inspection. We run a camera through every accessible duct run, starting with the return plenum and blower compartment. On Lennox ELITE and SIGNATURE systems we also pull static-pressure readings at the supply and return plenums to compare against manufacturer spec. The homeowner sees the footage in real time.
- 2
Written scope and flat price. Before any panel comes off, we deliver a written price for the full job - cleaning, sealing, parts, labor - under Haven Standard Clause 1. The price is per system, not per vent. No add-ons after the truck arrives.
- 3
Repair and cleaning execution. We clean with Rotobrush and Nikro negative-pressure extraction equipment, replace damaged flex or collars with Guardsman or OEM Lennox components, and seal all plenum joints and collar connections with mastic. Evaporator coils and blower assemblies are cleaned in place when accessible.
- 4
Post-service testing and balancing. We re-check static pressure, verify blower RPM against Lennox spec on variable-speed units, and balance supply dampers to even room-to-room temperatures. The iComfort thermostat is checked for accurate communication with the control board.
- 5
Documented Photo Record and warranty. Every run is photographed before and after. The complete photo set, written scope, and 365-Day Done Right Promise are delivered as a standard job record before we leave.
Lennox Products We Service & Install in Atlanta
We service and repair Lennox ELITE Series variable-speed furnaces and air conditioners (SL280V, EL296V, XC21), MERIT Series single-stage and two-stage systems (ML180, ML193, 14ACX), SIGNATURE Series communicating equipment (SL297NV, XC25), and the Dave Lennox Signature Collection.

We Also Service These Brands
CleanRun is not a single-brand shop. We service Trane and Carrier systems with the same protocol - video inspection, written price, documented photo record - and our technicians carry cross-brand airflow specs for the mixed-manufacturer neighborhoods common across Cobb, DeKalb, and Gwinnett counties.
FAQs - Lennox Air Duct Cleaning Service in Atlanta
Yes, it can be. The iComfort communicating thermostat on SIGNATURE and some ELITE systems exchanges data with the control board via a low-voltage protocol. If a previous cleaner disconnected or damaged the communication wiring between the thermostat and the board, or if static pressure shifted enough to trigger a safety limit, the system will throw a generic “System Malfunction” rather than a specific error code. We diagnose the actual cause - wiring, pressure, or component failure - rather than resetting and hoping. Call (470) 495-9370 if you’re seeing repeated malfunctions.
Yes. The ECM blower in an EL296V or SL280V modulates speed to maintain programmed airflow against duct restriction. Standard cleaning that doesn’t address collapsed flex runs or plenum leaks leaves the blower fighting the same restriction, which shortens motor life and wastes energy. We clean and seal simultaneously, then verify static pressure is within Lennox spec before we leave.
In Atlanta’s climate, we recommend evaporator coil inspection every two to three years and full heat exchanger inspection at the same interval for furnaces in continuous use. The combination of high pollen load and sustained humidity above 60% means microbial growth establishes faster here than in drier Southern metros. A coil that looks clean in March can show fin fouling by August. Call (470) 495-9370 to schedule video inspection and we’ll show you what your coil actually looks like.
Our duct cleaning and sealing methods do not void Lennox equipment warranties. We do not alter factory wiring, control programming, or refrigerant circuits. For repairs involving communicating controls or sealed combustion components, we use OEM-compatible parts installed to manufacturer spec. As an independent provider, we document our work so any future warranty claim has a clear service history.
Whistling at a return register usually indicates high velocity through a restricted opening - often a collapsed flex run, an undersized return duct, or a leak pulling attic air through a small gap. On Lennox systems with variable-speed blowers, the motor may be ramping up to compensate, which makes the whistle more pronounced. We run video inspection to distinguish between a sealing issue, a cleaning issue, and a sizing issue. The fix differs for each. Call (470) 495-9370 and we’ll show you what the camera found.
Complete Lennox air duct cleaning in Atlanta typically runs $249 to $399 for a standard residential system, depending on total ductwork length, number of returns, and accessibility. Larger homes with multiple systems, extensive flex duct replacement, or evaporator coil cleaning may run higher. We deliver the exact written price before work starts - no per-vent add-ons, no coupon bait-and-switch. Call (470) 495-9370 for a free estimate with numbers attached.
