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.
Lennox Air Duct Cleaning in Alpharetta, GA | CleanRun Air Duct Cleaning Johns Creek
Air Duct Cleaning in Alpharetta for Lennox systems typically runs $380-$680 for a complete duct cleaning on a multi-zone residential system, with most jobs scheduled within a week. What separates our work here is the intersection: we understand how Lennox ECM blowers and zone controls behave inside the exact flex-duct infrastructure that dominates Alpharetta’s 1990s-2000s planned communities. We are not authorized, sponsored, or endorsed by Lennox. We are simply an independent metro-Atlanta duct cleaning company that works on Lennox systems every week and documents what we find before quoting a price. Call (470) 326-1926 for a written estimate.
Why Alpharetta Residents Choose Us for Lennox Service
We have cleaned ductwork in Alpharetta homes since 2013. The crews know the difference between a Lennox Merit air handler from 2002 and a Dave Lennox Signature Collection SL-series from 2015, and they know which ones were paired with the undersized flex runs that tract builders favored in Windward and comparable communities.
Tomas Reyes, our owner, trained in HVAC fundamentals at CUNY Kingsborough Community College in Brooklyn before spending the better part of two decades doing hands-on duct work across the Southeast. He grew up in Queens, where summers helping his uncle patch window units taught him that what happens inside a system matters more than what you can see from the outside. For the past several years, Tomas and his crew have serviced homes throughout the area, including neighborhoods around the Medlock Bridge corridor, where two-story builds with zoned systems tend to hide the worst accumulation behind secondary return boxes. The photo goes first. The price comes after.
We use OEM-spec Lennox parts when a direct match matters for blower motors and filters, and quality aftermarket equivalents for media cabinets and flex connectors where performance is equal. Every job starts with a written price before any work begins, under Haven Standard Clause 1. Every duct run is photographed before and after. The 365-Day Done Right Promise is backed in writing, not just stated in marketing copy.
Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman. Customers can look up every brand independently. Technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. Alpharetta service area coverage includes same-week scheduling for most Lennox duct cleaning and repair requests.
Common Lennox Air Duct Cleaning Problems We Solve in Alpharetta

- Sagging flex duct pulling from boot collars. In Alpharetta’s 1990s-2000s builds, original flex duct was installed rapidly during subdivision construction and secured with minimal support. The weight of accumulated debris, combined with attic heat cycling, causes the flex to sag away from Lennox boot collars. Low-point pockets form. We find these packed with pine pollen, blown-in insulation fibers, and mold that homeowners never see because airflow “seems fine” from the registers below.
- ECM blower overcompensation masking restrictions. Many Lennox air handlers use variable-speed ECM blowers designed to maintain target airflow. When the return plenum loads with Alpharetta’s heavy spring pollen, the blower ramps up to compensate. The homeowner notices nothing until energy bills spike or the motor fails prematurely. Our video inspection catches the restriction the blower was hiding.
- Condensate and mold in humid attic installations. Alpharetta’s relative humidity stays above 70% from May through September. Lennox air handlers in unconditioned attics experience repeated condensation cycles. Mold colonizes coil faces and insulation blankets. Filter changes do not reach this. We document it with before-and-after photography of the plenum and coil cabinet.
- Zoning failures from undersupported flex runs. Lennox multi-zone systems in large Alpharetta homes depend on properly sized and supported ductwork. When flex runs sag or collapse, one zone starves for airflow while the thermostat reports a satisfied setpoint. The zone controller shows green. The room stays warm. We map airflow at each register to find the disconnect.
- Return duct loading from pollen surge. Alpharetta’s retained tree canopy and Piedmont position produce some of the highest residential pollen exposure in metro Atlanta. The yellow pine surge each spring loads into Lennox return-air systems and settles in horizontal flex duct runs. Cleaning the supply side alone misses where most debris enters.

AfterLennox Service in Alpharetta: What Local Conditions Mean for Your Equipment
Alpharetta’s explosive tech-boom growth from roughly 1988-2005 produced something no neighboring city replicates: block after block of large, 3,000-5,000+ square foot planned-community homes, many now 20-35 years old, with complex multi-zone flex duct systems installed rapidly during tract construction. These systems are at exactly the age where sagging, joint separation, and deep debris accumulation become critical. The concentration is the point. In Johns Creek or Roswell, you will find similar vintage homes, but not this density of identical systems failing in identical ways simultaneously.
For Lennox owners specifically, this matters because Lennox ECM blowers and zone controls are designed to modulate precisely. They assume ductwork that delivers what the specification sheet promises. When a Windward home’s original flex duct has sagged off three boot collars and created low-point debris pockets, the Lennox system does not throw a fault code. It compensates. The homeowner pays in efficiency and premature component wear until someone opens the plenum and shows them what the camera found. We have done this hundreds of times in Alpharetta. The pattern is recognizable once you have seen it enough.
Lennox Models & Products We Service in Alpharetta

We regularly service Lennox Merit series furnaces and air handlers, many original to 1990s-2000s Alpharetta builds; Lennox Elite series split systems; Lennox Dave Lennox Signature Collection SL-series furnaces; and Lennox Magic-Pak sealed-combustion units found in some multi-zone installations. Lennox sales & service from our team means familiarity with these product lines, not manufacturer affiliation.
We stock OEM-spec blower motors, filters, and ignition components for common Lennox models, plus quality aftermarket media cabinets and flex connectors. For most 20-30 year old Lennox systems in Alpharetta, duct sealing and repair is the honest first move. Full replacement only makes sense when the heat exchanger or compressor is at end of life. We will say so in writing.

FAQs - Lennox Air Duct Cleaning in Alpharetta
The filter protects the coil, not the plenum or flex duct downstream. In Alpharetta’s humid attics, condensation cycles breed mold on coil faces, insulation blankets, and inside sagging flex runs where air stagnates. Changing the filter does not reach these areas. Our video inspection locates the source, and cleaning includes the full return path, not just the supply registers. Call (470) 326-1926 to schedule.
No. Lennox equipment warranties cover defects in the furnace, air handler, or coil. Ductwork is a separate building component. We are an independent service provider, not Lennox-authorized, and we document what we find so you have a record for any warranty claim on the equipment itself. Flex duct repair and cleaning are maintenance items, not warranty items.
Windward and comparable 1990s communities were built during rapid subdivision construction with large floor plans, multiple zones, and flex duct installed quickly with minimal support. The systems are now 20-35 years old, the age where sagging and joint separation peak. Newer Alpharetta builds use more rigid duct and better support practices. The density of same-vintage, oversized flex-duct homes here is unique to this area.
Usually yes. When a flex run sags or collapses, the zone damper may close on schedule while the actual room receives inadequate airflow. The thermostat in the hallway reads satisfied. The bedroom does not. We map airflow at each register and inspect the duct path to find where the disconnect occurs. This is common in Alpharetta’s multi-zone Lennox installations.
Alpharetta’s yellow pine pollen surge loads into return-air systems and settles in horizontal flex duct runs, particularly low points created by sagging. The return plenum becomes a reservoir. Lennox ECM blowers compensate by ramping up, which masks the restriction until efficiency drops or the motor fails. We clean the full return path, not just supply registers, and photograph the difference. Call (470) 326-1926 for a written estimate before this spring’s peak.
