Johns Creek’s residential boom from the late 1980s through the mid-2000s produced thousands of upscale homes, typically 3,500 to 6,000-plus square feet, with multi-zone Lennox HVAC systems whose original flexible ductwork is now 20 to 40 years old. In the vast majority of these homes, that ductwork has never had professional Air Duct Cleaning services. The city’s heavily wooded lots and proximity to the Chattahoochee River corridor create some of the highest localized spring pollen loads in the Atlanta metro. That pollen, combined with red Georgia clay construction dust and humidity-driven mold, accumulates in extensive duct networks that were designed for airflow, not filtration.

Why Trust CleanRun Air Duct Cleaning Johns Creek for Your Lennox Air Duct Cleaning?

Tomas Reyes, our owner, grew up in Queens, New York, where he spent summers helping his uncle patch window units in apartment buildings. Not glamorous work, but it taught him that what happens inside a system matters more than what you can see from the outside. He 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. For the past several years, Tomas and our crew have provided Lennox service in Duluth and throughout Johns Creek, including neighborhoods around the Medlock Bridge corridor, where two-story builds with zoned systems tend to hide the worst accumulation behind secondary return boxes.

Our technicians have logged thousands of hours on Lennox service in Alpharetta and on Lennox residential and light-commercial systems, from the Dave Lennox Signature Collection to older Merit and Elite series. We keep diagnostic tools and replacement components for Lennox’s variable-speed and communicating equipment on every truck. This matters because a Lennox SL280V or EL296V does not behave like a single-stage air mover. The ECM blower ramps to maintain static pressure, and when return-side leaks pull unfiltered attic dust into the plenum, the coil and wheel foul faster than on constant-torque equipment. We know the difference. We clean, seal, and repair Lennox duct systems without treating them like generic hardware.

Every job is backed by our 365-Day Done Right Promise, documented in writing. Every crew member is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. And every customer receives a Documented Photo Record of every duct run, before and after, as a standard deliverable.

Common Lennox Air Duct Cleaning Problems We Fix in Johns Creek

• Negative-pressure duct leakage on Lennox variable-speed air handlers. The ECM blower in a Dave Lennox Signature SL280V or SL297V ramps to maintain programmed static pressure. When return plenums are poorly sealed, that negative pressure pulls unfiltered attic dust directly through gaps. In Johns Creek attics that regularly exceed 140°F, the dust bakes onto the evaporator coil and blower wheel. We find this on nearly every Signature and Elite series install we open. The fix is not more filtration. It is sealing the return plenum with mastic and restoring proper static pressure.
• Premature blower-motor and wheel fouling in horizontal-discharge Lennox units. Lennox air handlers that discharge horizontally into a tight return drop, common in the space-constrained attics of Medlock Bridge and St. Ives homes, accumulate fine drywall dust and pet hair on the wheel. The material binds to the blades, raises amp draw, and trips the motor’s internal overload. We pull and clean the wheel, measure running amps against the nameplate, and seal the return drop to prevent recurrence.
• Evaporator coil ‘blanketing’ on Lennox R-410A cased coils. These coils, often paired with SL or EL outdoor units, suffer when return-side leaks let insulation fibers and dust pack the fin face. The result is high head pressure, short cycling, and premature compressor wear. In Johns Creek’s humidity, the packed fins also hold moisture and support mold growth. We wash the coil with foaming cleaner and a low-pressure rinse, then verify temperature split across the coil before we leave.
• Flex-duct collapse and inner-liner delamination in attic runs. Lennox systems with long flex-duct runs in Johns Creek attics suffer from Georgia’s extreme summer heat. The inner liner peels and delaminates, collapsing shut and starving specific rooms even though the equipment runs at full capacity. We photograph the damage, replace the affected runs with new R-8 flex duct, and balance airflow with a digital manometer.
• Zone imbalance in Lennox Harmony III systems. The Harmony III zoning system with variable-speed air handlers depends on accurate duct sizing and sealed dampers. In Johns Creek’s large homes, we routinely find dampers stuck with dust or bypass ducts dumping conditioned air into the attic. One zone stays stuffy while another over-cools. We clean the dampers, verify actuator operation, and seal bypass leakage.

Lennox Parts & Our Repair-vs-Replace Approach

We use factory OEM Lennox parts for critical components like blower motors, control boards, and coil assemblies when they are available. For duct repairs, we source high-quality aftermarket flex duct, mastic, and sealing materials that meet or exceed Lennox installation specifications. Our trucks stock common Lennox blower motors, capacitors, and contactors for fast turnaround on Johns Creek jobs.

For older Lennox Merit or Elite equipment, we give an honest repair-vs-replace assessment. If the air handler is over 15 years old and the coil is leaking, we will tell you when sealing and cleaning alone will not restore performance. Haven Standard Clause 1 requires a written price before any work starts, so you will have that number in hand before you decide. Call (470) 326-1926 for a free second opinion on any written estimate.

Our Lennox Service Process - Step by Step

1. 1
   Diagnosis with documented evidence. We start with a full system inspection, including static-pressure measurement at the air handler and visual assessment of accessible ductwork. For Lennox variable-speed systems, we check blower amp draw and ECM module fault history. We photograph the inside of every accessible duct run before touching anything.
2. 2
   Written scope and price. Before any cleaning or repair begins, we deliver a written price under Haven Standard Clause 1. The scope specifies which duct runs will be cleaned, whether the evaporator coil requires washing, and any repair items like flex-duct replacement or plenum sealing. No work starts until you have that document.
3. 3
   Cleaning and repair. We use Rotobrush and Nikro negative-pressure extraction equipment for duct cleaning, Abatement Technologies HEPA filtration for containment, and professional-grade mastic and foil tape for sealing. Evaporator coils are foamed and rinsed. Blower wheels are pulled and cleaned when indicated. We name our equipment brands so you can verify specifications independently.
4. 4
   Testing and verification. After cleaning and repair, we re-measure static pressure and verify temperature split across the coil. For zoned Lennox systems, we confirm damper operation and zone balance. The system must meet manufacturer specifications before we consider the job complete.
5. 5
   Documented photo record and warranty. We deliver before-and-after photographs of every duct run, plus the written scope and our 365-Day Done Right Promise, before the crew leaves. If the work is not right, we make it right. That is in writing, not subject to manager approval.
