Lennox Air Duct Cleaning in Kennesaw, GA | Mortons Air Duct Sandy Springs
We provide independent Lennox Air Duct Cleaning - Kennesaw and repair across Kennesaw, and we’re not affiliated with Lennox corporate. The one thing that sets our Lennox work apart here is that we know exactly how Cobb County’s red clay dust and humid summers interact with Lennox variable-speed blowers and high-static duct design. Most Lennox owners in Kennesaw don’t need a new system. They need someone who can prove the airflow is starving before recommending anything. Call (229) 495-2691 and Paul Adeyemi will tell you exactly what he’s going to do, and exactly what it will cost, before a single hose gets unrolled.
Why Kennesaw Residents Choose Us for Lennox Service
Our technicians have spent years working on Lennox ductwork in Cobb County humidity. We know the Signature® Collection and Elite® Series systems well enough to predict where they clog and where airflow drops first. Paul trained in HVAC technology at Los Angeles Trade-Technical College, and he brings that mechanical background to every Lennox inspection in Kennesaw. He explains what the video inspection shows, what the cleaning will address, and what the final number is before any work begins. Families with kids and pets in Kennesaw Acres and Legacy Park call us because we put shoe covers on before stepping inside, lay down drop cloths around the work area, and use quieter tools when there’s a toddler napping down the hall. We’re part of the Cedarwell family of independent companies, and every visit carries the Cedarwell Care Promise: a written price before work starts, a photo of the clean-up before the crew leaves, and the 365-Day Done Right Promise stamped on every job. We also handle broader Lennox sales & service questions when they come up.

Common Lennox Air Duct Cleaning Problems We Solve in Kennesaw
- Signature® variable-speed blowers coated in red dust. Barrett Parkway construction throws fine Cobb County clay into the air, and Lennox Signature® systems pull it straight through return ducts and onto the evaporator coil. We clean the coil and blower wheel before the ECM motor strains against the restriction.
- Elite® Series flex duct sagging in Legacy Park attics. Georgia attic heat softens older flex duct, and sagging sections trap pollen and lower static pressure. We repair or replace the runs and restore the airflow the system was designed for.
- Lennox PureAir™ cabinet mold during humid summers. Kennesaw’s muggy season pushes moisture into the PureAir™ media frame, and mold grows there before the homeowner smells it. We clean the coil and blower to eliminate the odor at the source.
- Merit® return ducts too small for modern heat pumps. Homes built in the 1980s in Kennesaw Acres often have undersized return ductwork that was fine for the original furnace but barely adequate for a modern Lennox heat pump. Duct sealing reduces leakage and lets the system breathe.
- Construction debris in newer Lennox installs. West-of-I-75 subdivisions built after 2015 often have drywall dust caked on the blower wheel from the original build-out. The first homeowner inherits it, and a standard filter never catches it. Our video inspection finds it in minutes.
Lennox Service in Kennesaw: What Local Conditions Mean for Your Equipment
Homes west of I-75 in Kennesaw, especially subdivisions built after 2015 near Kennesaw State University’s Marietta campus, often have Lennox variable-speed air handlers that were never commissioned properly after construction. The original drywall dust from framing and finishing settles into the blower wheel and evaporator coil before the first family even moves in, and because the system was never set up to match the home’s actual static pressure, it struggles from day one. We routinely find this on our video inspections. It’s not a Lennox defect. It’s a commissioning gap that turned into a dust problem, and it’s specific to the newer construction surge in this part of Cobb County. Our crew pulled an Elite® Series air handler in Legacy Park where the Lennox evaporator coil was coated with red clay dust from a Barrett Parkway build site a quarter-mile away. We showed the homeowner the dust blanket on the coil and the sagging return flex, then performed a full system cleaning, flex duct repair, and mastic sealing. Airflow jumped from 1,100 to 1,450 CFM on the same blower speed, and their allergy complaints dropped within a week. That’s the kind of Lennox work we do in Kennesaw every month.
Lennox Models & Products We Service in Kennesaw
We clean and repair ductwork for the full Lennox residential lineup: Signature® Collection systems including the XP25 heat pump with matched air handlers, Elite® Series equipment like the EL296V, Merit® Series units including the ML180, and Lennox Healthy Climate® ventilation attachments like the PureAir™ air purification cabinet. On parts, we default to OEM-style Lennox-compatible filters and mastic sealant because duct leaks around coil cabinets need exact fits. For basic flex duct replacement, quality aftermarket material from HVAC suppliers performs just as well and keeps your invoice lower. We never replace a Lennox air handler or condenser before exhausting duct cleaning, sealing, and airflow verification. Most “broken” Lennox units in Kennesaw are simply starving for air.

FAQs – Lennox Air Duct Cleaning in Kennesaw
The red dust is Cobb County clay from construction sites along Barrett Parkway and newer developments west of I-75. Lennox Signature® systems run variable-speed blowers at low airflow for long cycles, which means dust that enters the return settles in supply ducts instead of blowing through. A good filter helps, but the dust that’s already in the system stays there until it’s removed. Call (229) 495-2691 for an inspection and an exact quote.
We remove the media filter and catalyst cartridge before cleaning the cabinet interior, then clean the coil and blower separately. The catalyst and filter are inspected and reinstalled, never scrubbed or sprayed with anything that would degrade them. Kennesaw’s humid summers make this a common service call, and mold on the media frame is the usual culprit. Call us for a free estimate.
Yes. Sagging flex duct, especially in Legacy Park and other 1990s neighborhoods, increases static pressure and reduces airflow across the heat exchanger or coil. The system can overheat or freeze and shut down early. We repair or replace the sagging runs and retest airflow before considering anything else. Call (229) 495-2691 and we’ll check it out.
You don’t need a different method, but you do need a technician who checks for mold on the coil and blower, not just dust in the ducts. Kennesaw’s humid subtropical climate means moisture collects inside the system between cycles, and standard duct cleaning that skips the coil leaves the mold behind. We include coil and blower cleaning in every Lennox job. Call for a free estimate.
The ECM blower motor in variable-speed Signature® and Elite® systems. When dust and restriction force the motor to work harder than designed, it runs hot and fails early. Lennox warranty covers the part, but labor isn’t free, and the root cause is usually the dirty coil and restricted ductwork that preceded it. Cleaning the system is far cheaper than a blower motor replacement. Call (229) 495-2691 for an exact quote.
