Lennox Air Duct Cleaning in Marietta, GA | Linden Air Duct Marietta
Air Duct Cleaning in Marietta for Lennox systems typically costs $350 – $650 for a full system, depending on home size and how much buildup has accumulated in the runs. We’re an independent Lennox service provider, not factory-affiliated, which means we tell you straight what’s in the ducts and what it costs to fix. What sets our Lennox work apart here is simple: we know how Marietta’s 1960s-80s duct architecture and brutal spring pollen turn a standard Lennox system into something that fails differently than it would in Atlanta. Call (912) 405-8840 and we’ll give you a written price before any work starts.
Why Marietta Residents Choose Us for Lennox Service
We work on Lennox duct systems across Marietta’s older housing stock every week. Flexible duct in 1970s split-levels, metal runs in historic district homes, variable-speed air handlers that have been fighting Georgia humidity for two decades. Our technicians train specifically on Lennox return-side restrictions and the way deteriorated duct materials interact with the brand’s filtration and airflow design. We treat the duct system as part of the whole Lennox installation, not a separate afterthought.
Marcus Veale, our owner, got his HVAC coursework done at Los Angeles Trade-Technical College and has been working in the greater Marietta area for well over a decade. His crews have logged time in homes all along the East Cobb corridor, including jobs near Kennesaw Mountain where older ranch-style houses hide some of the worst buildup we’ve ever pulled out of a system. That experience means when a Lennox Elite Series system off Whitlock Avenue starts losing airflow, we already know what we’re likely to find before the camera goes in. For Lennox sales & service, independent expertise matters more than a logo on the van.

Common Lennox Air Duct Cleaning Problems We Solve in Marietta
- Pollen-clogged return ducts. Oak and pine pollen blinds over Lennox air filter racks every spring, then passes into the return side and coats the walls. In older metal runs, you’ll see visible yellow streaks inside. We pull that out with negative-pressure extraction and show you the before-and-after footage.
- Sagging flex duct on 1960s-80s Lennox installs. Original flex duct separates at the boots over time, pulling attic insulation and humid air into the airstream. We reseal or replace with UL-listed flex that meets or exceeds the original spec.
- Microbial growth on variable-speed air handlers. Marietta’s summer humidity is rough on Lennox variable-speed blowers. When duct leakage pulls in unconditioned crawlspace air, you get moisture where it shouldn’t be. We clean the blower and evaporator surfaces without pulling the air handler apart.
- Deteriorated fiberglass duct board. Fiberglass duct board from original Lennox installs breaks down over decades. The particles end up in your living space and the ducts lose structural integrity. We assess on a job-by-job basis, and we don’t push replacement when cleaning and sealing will do the job.
- Asbestos-wrapped metal ducts in historic districts. Homes along Whitlock Avenue and other historic Marietta corridors often have original metal ducts wrapped in asbestos tape that degrades over time. Pinholes and separated joints then shower insulation particles and heated attic air into the house. We handle this carefully under containment.
Lennox Service in Marietta: What Local Conditions Mean for Your Equipment
In Marietta’s Whitlock Avenue historic district, many homes still have original metal return ducts wrapped in asbestos tape. Our video inspections routinely find pollen packed so thick inside those returns that it looks like a solid layer of yellow insulation. You would rarely see that in Atlanta’s newer infill housing, because those homes don’t have five decades of mature-tree pollen cycling through original 1960s ductwork. For Lennox owners in Marietta, that means the return side is the first place airflow dies. A variable-speed Lennox air handler compensates by ramping up, which pulls even more debris through gaps and makes the problem worse. That’s the cycle we break: clean the return, seal the joints, and the system stops working against itself. Our crew was called to a split-level off Whitlock Avenue where a Lennox Elite Series was losing airflow and the homeowner had allergy symptoms even with a new filter. The video inspection found the original metal return wrapped in degrading asbestos tape, a solid coat of yellow pollen inside, and a separated joint pulling attic heat into the system. We sealed the joint with mastic, removed surface debris under containment, ran an air wash through the return and supply runs. Static pressure dropped and the system stopped recirculating pollen. That’s the job, done right.
Lennox Models & Products We Service in Marietta
We service duct systems across the full Lennox residential line: the Elite Series, Merit Series, Dave Lennox Signature Collection, and Lennox Healthy Climate filtration systems. For duct sealing and repairs, we use OEM-grade mastic and UL-listed flex duct that meets or exceeds original material specs. When HVAC components like coils or blowers need replacing, we recommend OEM Lennox parts because the tolerances are tighter and aftermarket parts can alter airflow characteristics. We keep common repair materials stocked locally, which means faster turnaround for Marietta jobs. If you’re in the broader Marietta service area, we can typically get eyes on your system faster than an out-of-town crew.

FAQs – Lennox Air Duct Cleaning in Marietta
Marietta’s mature oak and pine canopy dumps enormous amounts of fine pollen every spring, and the city’s humid subtropical climate keeps that pollen sticky and heavy. Older Lennox systems with original return ducts, especially in 1960s-80s split-levels, have larger gaps and looser filter racks, so more unfiltered air bypasses the filter entirely. Call (912) 405-8840 and we’ll show you exactly what’s in your returns before we quote anything.
It depends on material integrity. If the flex duct is sagging, separated at boots, or showing signs of the inner liner breaking down, cleaning alone won’t fix the problem. If it’s intact and just dirty, cleaning and sealing is often all you need. We decide based on what the video inspection shows, not on age alone, and we don’t push replacement when the existing duct can be cleaned and sealed.
Yes. We use access panels and specialized cleaning tools to reach the blower wheel and evaporator surfaces without disassembling the air handler. On Lennox variable-speed units, this is especially important because the blower housing is tight and pulling the whole assembly out adds hours and risk. We clean what needs cleaning and leave the rest alone.
No, but it requires a crew that knows how to work around it. Degrading asbestos tape should be left undisturbed unless it’s actively shedding, and surface debris removal needs to happen under containment. Our crews are trained to identify asbestos-wrapped ductwork and work around it safely. The bigger issue with old metal ducts is usually the separated joints and pinholes pulling attic air into the system, which we seal with mastic.
In most cases, yes. When return ducts pull in unconditioned humid air from a crawlspace or attic, the Lennox coil has to work harder to remove moisture, and you end up with higher indoor humidity even when the AC is running. Sealing those leaks stops the humid air from entering the airstream. Call (912) 405-8840 for a free estimate and we’ll test your system before recommending anything.
