Lennox Air Duct Cleaning in Marietta, GA | Cardinal Air Duct Marietta
We’re an independent Lennox air duct cleaning provider serving Marietta homeowners, and the short answer is this: most Lennox duct cleanings in Marietta run $325 – $525 for a typical single-system home, and the work usually takes half a day. What makes our Lennox work different here is that we know how Marietta’s humidity and older housing stock interact with Lennox equipment in ways a generic duct cleaner misses. Our technicians are trained on how Lennox duct systems integrate with their HVAC equipment, from the variable-speed air handlers in the Dave Lennox Signature Collection to the PureAir purification systems, and we clean without damaging sensitive ECM motors. If you own a Lennox system in Marietta, call (762) 216-4075 for a free estimate and a written price before any work begins.
Why Marietta Residents Choose Us for Lennox Service
Omar Haddad, who owns Cardinal Air Duct Marietta, trained in heating and ventilation at Los Angeles Trade-Technical College and spent years learning the difference between a duct that needs brushing and one that needs replacing without guessing. That experience matters here because Marietta’s housing stock demands it.
We service Lennox systems across the full range of what Marietta throws at them. Historic homes near the Square, 1960s ranch houses in east Marietta, 1980s split-levels in Sherwood Forest, and newer west Cobb construction all have different duct realities. A Lennox SLP98V variable-speed furnace in a 1972 split-level behaves differently than the same furnace in a 2005 subdivision home. We also stock OEM Lennox filters and MERV-rated media for fast turnaround, and we prefer commercial-grade mastic and UL-listed tapes for sealing work because they outperform factory tape in Marietta’s humid crawlspaces. For a broader picture of what we do across the area, see our Marietta service area page.

Common Lennox Air Duct Cleaning Problems We Solve in Marietta
Here are the specific failure patterns we see on Lennox systems in Marietta, week after week:
- Collapsed flex ducts in attic spaces near Lennox air handlers. Marietta’s hot, humid summers bake attic flex runs until they kink or collapse, especially in 1980s – 90s homes. The Lennox air handler keeps pulling, but the airflow is strangled, and debris collects right at the collapse point.
- Failing mastic at original metal duct joints in ranch homes. Many 1960s – 70s Marietta ranches still have original metal trunk lines. The mastic at those joints dries out and cracks, and Georgia red clay dust gets sucked in and coats the Lennox evaporator coil. That’s a massive efficiency loss on an XC16 or EL296V.
- Crumbling fiberboard return ducts in east Marietta. This is a problem you rarely see in newer west Cobb subdivisions. Original fiberboard returns shed particles that travel straight into Lennox blower motors and clog the secondary heat exchanger on high-efficiency gas furnaces.
- Undersized returns making Lennox blowers work harder. Older Marietta homes often have returns that were undersized from day one. The Lennox blower pulls harder to compensate, dragging more dust through the system and loading up filters prematurely.
- Mold in uninsulated metal ducts near the Square. Marietta’s historic homes often have original 1950s-era metal ducts that were never insulated. Humid summers cause condensation, and condensation breeds mold that recirculates through the Lennox system.
Every one of these problems is fixable. Our approach is to clean and seal before recommending any major Lennox component replacement, and we’ll tell you honestly if a repair beats a replacement on cost.
Lennox Service in Marietta: What Local Conditions Mean for Your Equipment
Here’s something specific about Marietta that most people don’t realize until they own a Lennox system here. Historic homes near the Square often have original 1950s-era metal ducts that were never insulated. When a Marietta summer pushes humidity into the 80s and 90s for weeks straight, those bare metal ducts sweat. Condensation forms, dust sticks to the moisture, and over time you get microbial growth inside the ducts. That same Lennox system then pulls that air across the evaporator coil and sends it through the house. A homeowner in Smyrna with newer construction generally doesn’t face this, because their ducts are insulated flex in modern attics. But in Marietta’s older neighborhoods, it’s routine. This is exactly why we run video inspection on Lennox duct systems before we quote an Air Duct Cleaning in Marietta, so we can see what’s actually in there and show you the before-and-after photos when we’re doneone.

AfterLennox Service Pricing in Marietta
Most standard Lennox air duct cleanings in Marietta run between $325 and $525 for a typical single-system home with up to 10 – 15 vents, while our Dryer Vent Cleaning in Marietta is priced separately. Larger homes, multiple systems, or heavily contaminated ductwork push the price higher. Duct sealing adds cost depending on how many joints need attention, and evaporator coil cleaning is usually priced separately but quoted upfront.
What drives the cost: system size, duct accessibility, how long it’s been since the last cleaning, and whether we’re dealing with collapsed flex runs or deteriorated fiberboard that needs more than brushing. Every estimate includes a video inspection so you’re not paying for guesses. We hand you a written price before a single duct is touched, and that price does not change at the door. Call (762) 216-4075 for an exact quote, and the estimate is free.

FAQs – Lennox Air Duct Cleaning in Marietta
Marietta’s long humid summers cause condensation on uninsulated metal ducts, especially in older homes near the Square and in crawlspaces. That moisture traps dust and can lead to mold growth that then circulates through your Lennox system every time the air handler runs. The fix is cleaning plus sealing and insulating those ducts where applicable. Call (762) 216-4075 and we’ll tell you what your specific system needs.
Yes, and it’s most noticeable on variable-speed models like the SLP98V or EL296V. Those furnaces modulate airflow precisely, and when the ducts are restricted by debris or collapsed flex, the system can’t move the air it’s designed to move. Cleaning and sealing restores static pressure and lets the variable-speed logic work as Lennox engineered it.
If you’re in an older east Marietta neighborhood and you’ve changed the filter and still see dust at the vents, you likely have failing ductwork upstream of the filter. Original fiberboard returns crumble and shed particles, and cracked mastic joints on metal trunks pull in attic or crawlspace dust. That dust bypasses the filter entirely and exits through your supply vents. A video inspection confirms it in minutes.
Yes, we service light commercial Lennox systems in Marietta, from small office suites to retail spaces. Commercial ductwork runs longer and dirtier than residential systems, and we bring the same Rotobrush and Nikro HEPA equipment to commercial jobs as we do to homes. Give us the building size and rough vent count when you call (762) 216-4075 and we’ll get you a written quote.
The evaporator coil sits directly in your airstream, and in Marietta’s humid climate it’s often wet, which means dust and biological growth collect there faster than anywhere else in the system. A dirty coil degrades cooling performance and recirculates whatever is growing on it. After we clean the coil, the air moving through your Lennox system is measurably cleaner, and the AC works less to hit the thermostat setting.
