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 Sandy Springs for Your Lennox Air Duct Cleaning?
Tomas Reyes, our owner, picked up his trade discipline studying HVAC systems at Bronx Community College before moving south and building CleanRun around one principle: show the customer what you found before you say what it costs. That principle applies directly to Lennox work. We know the cabinet dimensions on the ML14XC1, the tight return plenum geometry on the EL16XC1, and how the SL280’s variable-speed blower interacts with duct systems that have 40 years of Georgia dust baked into them.
Our technicians carry Lennox-compatible OEM-equivalent blower gaskets, cabinet sealants, and flex fittings on every truck. We don’t guess at parts. We don’t substitute generic hardware that won’t seat properly in a Lennox cabinet. And we document everything: the photo comes first, the invoice comes second. Haven Standard Clause 1 requires a written price before any panel comes off, and Haven Standard Clause 3 means every crew member is background-checked, uniformed, and identified by name before arrival.
In Sandy Springs specifically, we’ve learned what Air Duct Cleaning services need to address for Lennox systems in this housing stock. The ranch and split-level homes built between 1965 and 1990, when Fulton County oversight was lighter, often have original fiberglass duct board that crumbles where it meets a Lennox air handler. The Chattahoochee River corridor adds humidity that accelerates biofilm on cased coils. These aren’t theoretical problems. We’ve photographed them hundreds of times.
Common Lennox Air Duct Cleaning Problems We Fix in Sandy Springs

- Flex duct kinks and sags at attic truss penetrations. Lennox systems in Sandy Springs two-story homes, especially the Elite Series EL16XC1 and EL18XCV, often have flex runs routed behind finished attic insulation that compress or sag where they pass through trusses. The master suite gets half the designed airflow, the system runs longer, and the homeowner blames the thermostat. We find these with video inspection, photograph the sag, and reroute or support the run without cutting ceiling drywall when possible.
- Tight return plenums pulling dust through failed mastic. Lennox air handlers, particularly the Merit Series ML180 and ML14XC1, have compact cabinet designs that create high velocity at the return plenum joint. When the original mastic cracks, which it does in Georgia’s thermal expansion cycle, the blower pulls attic dust directly through the gap. The filter loads up in days. The blower wheel cakes over. We seal the plenum with fresh mastic, clean the wheel, and show the before-and-after on camera.
- Condensate management failures on cased coils. Lennox cased coils in Sandy Springs face five months of near-continuous summer humidity. The drain pan can develop standing moisture, and the wet coil becomes a growth medium. Microbial matter gets pulled through the return and distributed through the supply registers. We clean the coil with negative-pressure extraction, verify drain slope and flow, and document the pan condition. This is more common in homes near the Chattahoochee, where ground-level humidity runs higher.
- Foil-tape-only supply trunk connections losing pressure. Older Lennox Merit systems in Sandy Springs ranch homes were often installed with foil tape as the primary seal at collar joints. After 20+ years, the adhesive degrades. Pressure bleeds out at the joint. Rooms at the end of the trunk get weak airflow, and dust streaks appear at nearby registers from the turbulent leak. We reseal with mastic and mechanical fasteners, then pressure-test the trunk.
- Post-renovation contamination in Lennox systems. Sandy Springs has active renovation in neighborhoods from Hammond Drive to Spalding Drive. Drywall dust, fiberglass, and construction debris find their way into Lennox returns during remodels. The EL16XC1’s tight return plenum is especially vulnerable because there’s no volume to buffer the load. The blower wheel and evaporator coil cake up fast. We clean both components, inspect the filter rack for bypass gaps, and photograph the debris load so the homeowner sees what the system was breathing.

AfterLennox Parts & Our Repair-vs-Replace Approach
We stock genuine OEM-equivalent blower gaskets, cabinet sealants, and Lennox-compatible flex and metal fittings on our Sandy Springs trucks. For the ML14XC1, that means the correct gasket profile for the blower access panel. For the SL280, it’s the right width of cabinet edge seal. We don’t improvise.
But we’re direct about repair versus replacement. If a 20-year-old Lennox coil or cabinet is so degraded that cleaning won’t restore airflow, we’ll show you the photograph and explain why. Haven Standard Clause 1 applies: the written price covers what will actually solve the problem, not what we’d prefer to sell. Sometimes that’s a full system cleaning. Sometimes it’s sealing two joints and replacing a sagging flex run. Sometimes the honest recommendation is to replace the air handler because the cabinet is rusted through at the drain pan rail.
The 365-Day Done Right Promise means if we clean it and the underlying problem was structural, we make it right. No manager approval needed. It’s in writing on every job.

Our Lennox Service Process - Step by Step

- 1
Diagnosis with video inspection. We feed a camera through every accessible duct run, starting at the Lennox air handler. We look for separated collars, sagging flex, degraded duct board, and coil condition. The homeowner sees the feed in real time. We write up findings with measurements and photographs before any equipment moves.
- 2
Written scope and price. Based on what the camera showed, we deliver a written price for the exact work needed: full system cleaning, evaporator coil cleaning, air leak repair, or a combination. Haven Standard Clause 1: no work starts without a signature on the scope.
- 3
Cleaning and repair with documented photo record. We use Rotobrush and Nikro equipment for mechanical agitation and negative-pressure extraction, with Abatement Technologies HEPA containment when microbial growth is present. Every duct run is photographed before and after. Coil cleaning includes fin inspection and drain verification.
- 4
Pressure test and balance check. We verify that sealed joints hold, that rerouted flex delivers design airflow, and that room-to-room temperatures are within spec. If we repaired leaks, we measure the improvement.
- 5
Deliverable package and warranty. The homeowner receives the documented photo record, the written scope, and the 365-Day Done Right Promise in writing. Equipment used is noted: Rotobrush, Nikro, Abatement Technologies, and any Honeywell, Aprilaire, or Guardsman accessories installed.

FAQs - Lennox Air Duct Cleaning Service in Sandy Springs
No. We are an independent Lennox in Norcross and Sandy Springs service provider with no affiliation to Lennox Corporation. We diagnose, clean, seal, and repair Lennox air distribution systems based on field inspection, not manufacturer protocols. Our independence means we can recommend the full range of solutions, including duct repairs and third-party air quality accessories, without channel restrictions. Call (678) 904-9744 to discuss your system.
We use OEM-equivalent parts that match Lennox specifications, including blower gaskets, cabinet sealants, and flex fittings sized for Lennox plenum dimensions. For warranty-active systems, we verify that our cleaning and sealing methods won’t compromise coverage. We don’t install counterfeit parts, and we don’t charge OEM prices for generic hardware. The exact components are listed on your written scope before work begins.
A full Lennox duct system cleaning in a typical Sandy Springs ranch or split-level takes four to six hours, including video inspection, cleaning, coil service if needed, leak repair, and documentation. Two-story homes with longer flex runs, or systems with significant post-renovation contamination, may run longer. We don’t quote time; we quote the scope, and we stay until the photo record matches the written standard.
We service Lennox Merit Series (ML14XC1, ML13KC, ML180), Elite Series (EL16XC1, EL18XCV, SL280), and Dave Lennox Signature Collection (SL25XPV, SLP98) air handlers, plus Lennox Healthy Climate duct accessories. If your model isn’t on this list, call (678) 904-9744; we’ve likely worked on it, and we’ll confirm before scheduling.
Proper cleaning by a qualified technician does not void a Lennox warranty. We document our methods and equipment so warranty claims remain valid. Problems arise when untrained cleaners damage coils with improper chemicals or force, or when panels are removed and reinstalled incorrectly. Our technicians are trained on Lennox cabinet geometry, and every step is photographed for the job record. If your system is under warranty, we note the serial number and service details in writing.
Dust streaks at Lennox Merit Series supply registers almost always indicate a return-side leak pulling construction debris into the system. The ML180 and ML14XC1 have compact return plenums with limited buffering capacity; when a joint opens or the filter rack gaps, drywall dust bypasses the filter and cakes the blower wheel. The wheel then throws dust against the supply registers in pulses. We see this regularly in Sandy Springs renovation jobs. The fix is sealing the leak source, cleaning the wheel and coil, and verifying filter fit. Call (678) 904-9744 for a free estimate.
Usually, yes. Sandy Springs attics in 1960s-1980s construction often have sufficient access at the air handler and at truss penetrations to pull and support a new flex run. We use video inspection to map the existing route before any physical work. If the kink is at a truss penetration with no alternative path, we’ll show you the photograph and explain the options, including the rare case where a small access panel is necessary. We don’t cut drywall without written authorization.
Lennox cased coils are not inherently more prone to fouling than other manufacturers’ designs, but the compact cabinet geometry on Merit and Elite Series units leaves less margin for error. When condensate drainage slows or biofilm establishes, the coil loads up faster because there’s less air volume to dilute the effect. In Sandy Springs, where May through September humidity keeps systems running near-continuously, we recommend coil inspection every two to three years as part of full system maintenance. Homes near the Chattahoochee River corridor may need more frequent attention due to elevated ground-level moisture.
A full Lennox duct system cleaning for a typical Sandy Springs single-family home ranges from $450 to $890, depending on system size, accessibility, and whether evaporator coil cleaning and leak repair are included. Two-story homes with longer flex runs, or systems with significant contamination, fall at the higher end. We deliver a written price before any work starts, and we offer a Free Second Opinion on any competitor’s written estimate. Call (678) 904-9744 for an exact quote on your Lennox system.
