Lennox Air Duct Cleaning in Marietta, GA | Everest Air Duct Cleaning Service Georgia
Lennox repair in Smyrna and Marietta air duct cleaning runs $280–$520 for a full system, depending on whether your home has original flex duct from the 1980s–90s or a newer Signature Series setup with MERV 16 filtration. We’re independent specialists — not a Lennox-authorized dealer — which means our recommendations come from 20 years of hands-on Cobb County experience, not a manufacturer playbook. Scott Gray, our owner and lead technician, handles every job personally. Call (877) 565-7296 for a free estimate, often same-day.
Why Marietta Residents Choose Us for Lennox Service
We’ve cleaned over 500 Lennox service in Kennesaw and Marietta systems since 2012. That repetition matters. Scott Gray knows how the SL28XCV’s variable-speed blower responds when pollen packs into a sagging flex run, and he’s traced enough Merit Series condensate leaks to spot the crack pattern before water hits the duct lining.
Scott got his start in HVAC fundamentals at Georgia Piedmont Technical College, where a hands-on instructor drilled into him that the air inside a house tells you everything about how well it’s maintained. He’s spent two decades crawling through attics in 30008, 30060, 30062, and 30061 — and most of his repeat customers in the Decatur area know him by first name before the job is done. His wife finally stopped asking why he comes home smelling like insulation; his teenage son has already started tagging along on weekend jobs.
When you book with Everest, Scott shows up with Rotobrush contact-cleaning systems and Nikro HEPA vacuums — the same equipment trusted in commercial remediation work. We don’t dispatch franchise crews from a call center. You get 433 neighbors’ worth of verified trust at a 4.9-star average, and you get the owner on your ladder, not a substitute.
Common Lennox Air Duct Cleaning Problems We Solve in Marietta
- Flex duct sags trapping pollen and moisture in East Cobb attics. Lennox Signature Series variable-speed blower wheels clog within 2–3 years when mold grows in packed debris. We map the sag, access multiple attic points, and use rotary brush contact cleaning to restore airflow without tearing out sound duct structure.
- MERV 16 filter box gasket leaks on SL28XCV systems. Marietta’s humidity swells and degrades the gasket seal, bypassing filtration entirely. Cobb County’s loblolly pine pollen coats the evaporator coil instead, cutting efficiency and spreading allergens. We clean the coil and reseal the box with high-heat-rated aftermarket mastic.
- Merit Series ML14XC1 condensate pans cracking from attic heat cycles. Marietta’s unconditioned attics hit 140°F+ in summer. The thermal stress cracks plastic pans, and moisture pools in flex duct low points where standard vacuuming can’t reach it. We pull the pan, assess the duct, and clean the contamination source — not just the symptom.
- Original Lennox flex duct connectors losing mastic adhesion. West Marietta’s 1980s–90s ranch homes see this constantly. Dew-point swings between Georgia’s wet spring and dry winter brittle the original mastic, pulling attic air — unfiltered, often mold-laden — straight into supply runs. We scrape, re-mastic, and pressure-check.
- Multi-zone system debris accumulation in sprawling East Cobb homes. Near Barrett Parkway and Sandy Plains Road, 20-plus supply runs across 3,500–5,000 sq ft create low-point traps that truck-mount equipment alone can’t clear. We isolate zones, use Abatement Technologies air scrubbers during work, and verify with post-cleaning video inspection.
Lennox Service in Marietta: What Local Conditions Mean for Your Equipment
Marietta Air Duct Cleaning matters because proximity to the Chattahoochee River creates a humidity gradient most homeowners never consider. Homes in ZIPs 30008 and 30060 — West Marietta and the corridor toward the river — experience 15–20% higher attic humidity in summer than inland East Cobb properties. That difference isn’t abstract. It means condensation forms inside Lennox flex duct runs even when the equipment cycles normally, creating a microclimate that demands zone-specific cleaning protocols.
Scott Gray learned this the hard way. Early in his Marietta work, he cleaned a Signature Series system in 30060, pronounced it clear, and got a callback three months later for musty odors. The duct was clean — but the river-facing attic’s persistent humidity had recontaminated the lining through ambient moisture, not equipment failure. Now we adjust our sanitizing approach and drying time for 30008 and 30060 jobs, and we flag river-proximity homes for more frequent inspection intervals. East Cobb and Lennox service in Vinings clients in 30062 get a different protocol. That’s the difference between template service and local knowledge built job by job.
If your ducts haven’t been looked at in a decade, you don’t have an air quality problem — you have an air quality certainty.
Lennox Models & Products We Service in Marietta
We work on the full Lennox residential line: Signature Series including the SL28XCV and EL16XC1, Merit Series ML14XC1, the G60V furnace, and Dave Lennox Signature Collection units like the SLP98V. For variable-speed blower modules, coil sensors, and proprietary control boards, we source OEM components — warranty integrity and airflow accuracy depend on it. For flex duct, mastic, and sealants, we spec high-heat-rated aftermarket materials proven in Georgia attics. We stock common Lennox coil and blower configurations locally for fast Lennox repair in Sandy Springs and Marietta turnaround, and we carry Honeywell and Aprilaire air quality products for homeowners who want to close the loop from cleaned ducts to maintained clean air.

What drives cost: number of supply/return runs, accessibility of attic penetrations, whether we’re cleaning or also repairing sags and seal failures, and whether the system needs coil or blower attention beyond ductwork. Every estimate starts with a free inspection — Scott Gray walks the attic, runs the video scope, and tells you exactly what you’re paying for before any work begins.

FAQs — Lennox Air Duct Cleaning in Marietta
The MERV 16 filter box gasket is likely leaking. Marietta’s humidity swells the seal, bypassing filtration and sending pollen straight to the evaporator coil. The filter stays clean because dirty air isn’t passing through it. We reseal the box and clean the coil — call (877) 565-7296 for an exact quote; estimates are free.
Usually repair, not replacement. We inspect for mastic failure at connectors and structural tears from attic heat cycling. If the duct core is intact, we clean, reseal, and re-support — saving you thousands over full replacement. Scott Gray will show you the video inspection and give an honest assessment of whether replacement is actually necessary.
Every 3–4 years for homes in that corridor, given the multi-zone flex runs and heavy pollen load. If anyone in the home has allergies or you’ve done recent renovation, every 2–3 years. The Signature Series variable-speed blower is precise — but that precision means it’s also sensitive to debris accumulation.
Probably. Rain spikes ambient humidity, and if your flex duct has low-point sags with standing condensation or mold growth, the blower pushes that odor through supply grilles. We verify with video inspection and target the contamination source rather than masking it with deodorizer. Call (877) 565-7296 — we’ll pinpoint it.
We adjust. Signature Series units with variable-speed blowers need gentler rotary brush contact pressure to avoid damaging precision components; Merit Series systems often need more aggressive debris removal and condensate pan inspection due to their simpler blower design and known cracking issue. The equipment — Rotobrush, Nikro HEPA, Abatement Technologies scrubbers — stays the same; the technique and access plan change.
