Marietta’s combination of brutal attic heat, extreme pollen loads, and aging 1970s-1990s housing stock creates conditions that punish Lennox ductwork harder than most markets. We’ve cleaned and sealed Lennox systems from the Dave Lennox Signature Collection down through the Merit Series in ranch homes near the Marietta Square, in split-levels along the US-41 corridor, and in newer colonials throughout East Cobb, offering Air Duct Cleaning services tailored to each home. The camera doesn’t lie - and neither does the invoice.

Why Trust CleanRun Air Duct Cleaning Marietta for Your Lennox Air Duct Cleaning?

Tomas Reyes, our owner, grew up in the Bronx and picked up his first trade skills at Bronx Community College before deciding airflow systems were the puzzle worth solving. He has spent well over a decade doing hands-on duct work, and for several years now he and our crew have been the ones homeowners near the Marietta Square call when the HVAC tech says the ducts are the problem. Tomas arrives with a camera scope and leaves customers with before-and-after photos they can actually read - no vague summaries, no upsell theatre.

Our technicians know Lennox service in Kennesaw and Marietta equipment. We understand how the variable-speed blower in an Elite EL296V responds to static pressure changes, why the oversized evaporator coils in some Signature Collection installations strain returns, and where mastic seals fail on CBX27UH air handlers after a decade of Georgia thermal cycling. We stock Lennox-compatible OEM parts for critical sealed components and use quality aftermarket materials - Abatement Technologies HEPA filtration, Rotobrush agitation systems, Guardsman sealants - when they meet or exceed manufacturer specifications.

Every job follows Haven Standard Clause 1: written price before any work starts, every time. No exceptions. Haven Standard Clause 3: Verified Crews means our technicians are background-checked, uniformed, and identified by name before arrival. The 365-Day Done Right Promise backs every repair in writing - not as a policy subject to manager approval, but as a documented guarantee.

Common Lennox Air Duct Cleaning Problems We Fix in Marietta

• Static pressure imbalance and coil icing in EL296V and SLP98V systems. Lennox’s high-efficiency equipment often ships with oversized evaporator coils paired with returns that were adequate for older, less efficient systems. In Marietta, where flex duct liner has degraded after 30+ years in 140°F attics, the return side can’t move enough air. Static pressure climbs, the coil ices, and the variable-speed blower strains. We measure static pressure before and after cleaning, replace collapsed flex runs, and seal plenum connections with mastic to restore design airflow.
• Flex duct liner detachment in Merit Series and older Elite installations. The long flex duct runs common in Marietta’s ranch and split-level homes were never meant to survive this many thermal cycles. We’ve opened ceilings to find the inner liner of a 1990s flex duct completely separated from the wire helix, dumping fiberglass insulation into the airstream of an ML180 furnace. Our camera inspection identifies this before rotary brushing, which would shred the liner further.
• Mastic and mastic-tape seal failures at CBX27UH plenum connections. Lennox air handlers in unconditioned crawlspaces and attics see extreme expansion and contraction. The mastic seals at the supply plenum crack, pulling attic air - and Marietta’s pollen load - directly into the system. We remove failed mastic, clean the mating surfaces, and reseal with fresh mastic and mechanical fasteners.
• Dust accumulation on variable-speed blower wheels. The electronically commutated motors in Lennox’s Dave Lennox Signature Collection and Elite Series are precise, but they’re not forgiving. Construction drywall dust, Georgia red-clay particulate, and biological debris build up on the blower wheel, throwing off balance and causing vibration, bearing wear, and erratic CFM delivery. We clean the wheel in place or remove it for thorough washing, depending on contamination level.
• Return plenum contamination from failed duct board. In post-1970s neighborhoods near Franklin Road, we regularly find original duct board plenum boxes with interior liner separation - not just dirt, but structural failure. The fiberglass surface sheds particles into the return airstream. Standard rotary brushing accelerates this. We inspect with a borescope first, then use controlled negative-pressure extraction and gentle agitation, or recommend plenum replacement if delamination is advanced.

Lennox Parts & Our Repair-vs-Replace Approach

We favor genuine Lennox OEM parts for heat exchangers, coils, and sealed blower assemblies. For gaskets, mastic, flex duct, and register boots, we use high-quality aftermarket components from Honeywell, Aprilaire, and Guardsman when they meet or exceed OEM specifications. Our van stocks Lennox-compatible coils, blower wheels, and control boards for same-day resolution of common failures.

We advise repair over replacement unless the heat exchanger is cracked, the coil is leaking refrigerant at multiple points, or the duct board plenum has advanced delamination that cannot be sealed. Haven Standard Clause 1 means you get that recommendation in writing, with the price for each option, before we touch a single panel. Call (470) 516-9337 for a free second opinion on any written estimate - we’ll put our number next to it.

Our Lennox Service Process - Step by Step

1. 1
   Diagnosis with documented inspection. We borescope every duct run, photograph the evaporator coil and blower wheel, and measure static pressure across the system. For Lennox variable-capacity equipment, we also verify CFM delivery at each stage. You receive these photos before we discuss scope.
2. 2
   Written scope and price. Haven Standard Clause 1: we deliver a written price for evaporator coil cleaning, full system cleaning, duct sealing, or any combination - agreed before work starts. No per-vent pricing. One flat price per system.
3. 3
   Cleaning and repair with Lennox-compatible methods. We match our approach to your equipment. Rotary brushing for intact metal ductwork. Controlled negative-pressure extraction with gentle agitation for degraded flex or duct board. OEM or equivalent parts for all repairs.
4. 4
   Post-service testing and documentation. We remeasure static pressure, verify temperature split, and photograph every cleaned duct run. The documented photo record is delivered as a standard part of the job - not an extra, not upon request.
5. 5
   365-Day Done Right Promise activation. Your written guarantee goes into the job record. If the work is not right, we make it right.

FAQs - Lennox Air Duct Cleaning Service in Marietta

Is CleanRun Air Duct Cleaning Marietta authorized by Lennox?

No. We are an independent Lennox service provider, not affiliated with or authorized by Lennox Industries. Our expertise comes from hands-on experience with Lennox equipment across hundreds of Marietta homes, not from manufacturer endorsement. This independence allows us to recommend repair strategies and parts sources based on your system’s condition, not corporate policy.

Do you use genuine Lennox/OEM parts?

Yes, for critical sealed components: heat exchangers, evaporator coils, blower assemblies, and control boards. For gaskets, mastic, flex duct, and hardware, we use quality aftermarket parts from Guardsman, Honeywell, and Aprilaire when they meet or exceed OEM specifications. We specify which parts are OEM and which are equivalent in every written scope.

How long does Lennox service take?

Most full-system cleanings take 3-5 hours, depending on contamination level, duct accessibility, and whether we find collapsed flex or failed seals that need repair. A straightforward evaporator coil cleaning and blower service on an accessible Elite Series system might run 2-3 hours. We give you a time estimate with the written price before starting. Call (470) 516-9337 to schedule - estimates are free.

What Lennox models/series do you cover?

All current and recent-discontinued residential lines: Dave Lennox Signature Collection, Elite Series, Merit Series, and Complete Comfort Series air handlers. We also service older Lennox equipment still common in Marietta’s 1980s-1990s housing stock. If we encounter a rare or obsolete component we don’t stock, we source it within 24 hours.

Will service void my Lennox warranty?

Proper duct cleaning and sealing will not void your Lennox warranty. Warranty issues arise when untrained technicians damage components - using excessive pressure on coils, forcing brushes through degraded flex duct, or improperly reconnecting electrical. Our technicians are trained to Lennox-compatible methods, and we document every step. If your system is still under factory warranty, we note this in the job record and use OEM parts for any covered repairs.

How much does Lennox air duct cleaning cost in Marietta?

Full-system duct cleaning for a typical Marietta home runs $450-$850, depending on system size, contamination level, and accessibility. Evaporator coil cleaning adds $180-$340. Duct sealing with mastic and mechanical fasteners ranges $200-$500 for localized repairs, or $800-$1,400 for full-system sealing. We deliver one flat price per system in writing before work starts - no per-vent charges, no add-on surprises. Call (470) 516-9337 for an exact quote; estimates are free.
