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 Marietta Residents Choose Us for Lennox Service
We’ve cleaned and repaired Lennox ducted systems across Marietta since 2013 - from older G-series gas furnaces in 1970s ranch homes near the Square to modern Dave Lennox Signature Collection variable-speed communicating systems in newer builds off Canton Road. Lennox sales & service is not a sideline for us. We know how their cabinets seal, where their return plenums trap debris, and how their evaporator coils foul in Atlanta’s pollen corridor.
Tomas Reyes, our owner, grew up in the Bronx and learned airflow systems at Bronx Community College before spending over a decade doing hands-on duct work. He and his crew have become the ones homeowners near 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. The camera doesn’t lie - and neither does the invoice.
We use Lennox OEM parts when they are the right call - coils, control boards, communicating components - and high-quality aftermarket parts for generic items like flex duct, mastic, and filter grilles where the spec matches. Every job is quoted with a written price before work begins, backed by Haven Standard Clause 1, and every duct run is photographed before and after. That’s been our practice since our first job in 2013.
Common Lennox Air Duct Cleaning Problems We Solve in Marietta

- Return plenum and trunk delamination. Marietta’s attics hit 130-140°F regularly. The fiberglass duct board surrounding older Lennox air handlers sheds interior fibers into the airstream after decades of that heat cycling. We camera-inspect first - standard rotary brushes can tear separated liner and make the problem worse.
- Coil fouling from Atlanta pollen. Lennox evaporator coils sit behind filters that get overwhelmed by oak and pine loads five to ten times the national “very high” threshold. The coil and blower wheel cake with biological debris. Airflow drops. Rooms don’t cool evenly. We clean the coil and wheel as part of our standard scope.
- Flex duct collapse at takeoffs. Original flex branches on older Lennox systems sag and crush in attic heat, starving rooms of conditioned air and pulling unfiltered attic air through loose connections. We rebuild or replace crushed sections with proper support straps.
- High static pressure from undersized returns. Many Lennox installs in Marietta were paired with return ducts too small for the system. Once liner separation begins, the air handler pulls that fiberglass debris straight through the filter rack. We measure static pressure and document it.
- Mold and dust mite growth from persistent humidity. Marietta’s humid subtropical climate keeps ductwork moisture elevated year-round. Lennox systems with compromised plenum seals or crushed flex branches create dead-air zones where microbial growth establishes. We identify these zones with the camera before cleaning.

AfterLennox Service in Marietta: What Local Conditions Mean for Your Equipment
In the neighborhoods off the US-41 corridor and near the Franklin Road area, the original duct board plenum boxes on 1970s-1990s homes are often separating at the interior liner - not merely dirty, but structurally compromised. We camera-inspect before any brushing because standard rotary tools can tear that liner and release fiberglass fibers into the airstream. This is not a theoretical concern. On a split-level off Franklin Road, our tech pulled a Lennox air handler cabinet that had been running in a 138°F attic and found the return plenum’s duct board liner separating, shedding fibers into the supply trunk. We camera-inspected first, then hand-cleaned the trunk rather than brushing it, sealed the separated sections with mastic, cleaned the pollen-fouled evaporator coil, and rebuilt a crushed flex branch feeding the upstairs bedrooms - supply airflow at the farthest register came back to spec. The homeowner said the musty smell in the back bedrooms finally went away.
Marietta sits inside one of the worst seasonal pollen corridors in the United States. The dense canopy of mature loblolly pines and oaks deposits extraordinary airborne loads each spring and fall, and Marietta’s high year-round humidity causes that pollen and mold spores to cake onto duct surfaces faster than in drier metros. For Lennox owners, this means filters clog faster, coils foul deeper, and the biological debris that reaches the ductwork bonds more stubbornly to liner surfaces. The city’s dominant housing stock - 1960s-1990s ranch and colonial-style homes with flex duct and duct-board systems running through brutally hot unconditioned attics - accelerates liner degradation. Duct cleaning here often uncovers contamination and structural deterioration simultaneously. That’s why our Dryer Vent Cleaning in Marietta and standard visit includes video inspection, flex duct repair capability, and evaporator coil cleaning - not just vacuum noise.
Lennox Models & Products We Service in Marietta

We work on the full range of Lennox residential equipment found in Marietta service area homes:
- Lennox Merit Series - 14ACX/13ACX-style air conditioners with matching indoor units, common in entry-level installs from the 2000s-2010s.
- Lennox Elite Series - XC/EL heat pumps and air handlers, the mid-tier workhorse in many Cobb County homes.
- Dave Lennox Signature Collection - SL/XC series variable-speed communicating systems; we clean these with protocols that protect the sensitive control boards and communicating components.
- Older Lennox G-series - gas furnaces and air handlers from the 1980s-1990s, still running in original ranch and split-level homes across Marietta.
We stock OEM Lennox coils, control boards, and communicating components locally for fast Marietta turnaround. For generic items - flex duct, mastic, filter grilles - we use high-quality aftermarket parts where the spec matches. If your Lennox air handler is 20+ years old with failed coils and delaminating duct board, we’ll tell you honestly when repair dollars are better spent on replacement rather than stacking fixes on a worn system.

FAQs - Lennox Air Duct Cleaning in Marietta
Yes. In Marietta’s 130-140°F attics, the fiberglass duct board surrounding older Lennox air handlers commonly shows interior liner separation after 30-50 years of heat cycling. Our camera scope reveals delamination, debris buildup, and fiber shedding that visual inspection from the register cannot catch. Call (470) 516-9337 to schedule a camera inspection - estimates are free.
Atlanta-area pollen counts routinely hit five to ten times the national “very high” threshold, and Marietta’s humidity makes that biological debris stick to Lennox evaporator coils rather than passing through. Standard filters clog quickly and bypass debris to the coil and blower wheel. We clean the coil and wheel as part of our standard scope and document the condition with photos.
Yes. We use cleaning protocols that protect the sensitive control boards and communicating components in SL/XC series systems. We do not apply high-pressure or liquid methods near electronic components. The system is powered down, components are protected, and the documented photo record shows what was done.
It depends on condition. If the flex duct is crushed, torn, or the inner liner is degraded from attic heat, replacement is usually the better use of money. If the damage is limited to a few takeoffs or sag points, targeted repair with proper support straps can restore airflow. We camera-inspect and give you a written recommendation either way - no pressure to replace what doesn’t need it.
Marietta’s humid subtropical climate keeps ductwork moisture elevated for much of the year, creating persistent conditions for mold and dust mite growth - even in homes that run AC heavily in summer. Lennox systems with compromised plenum seals or crushed flex branches create dead-air zones where microbial growth establishes. Our camera inspection identifies these zones before cleaning, and we address moisture entry points as part of repair work. Call (470) 516-9337 for a full assessment.
