We are not affiliated with or authorized by Lennox. That independence matters. We diagnose what is actually restricting airflow in your system instead of defaulting to manufacturer talking points. Tomas Reyes, our owner, learned the mechanical trades at Bronx Community College and spent nearly two decades on HVAC systems before relocating south and putting in years on residential and commercial ductwork throughout Alpharetta. He still finds construction debris in the ductwork of newer builds near Avalon that surprises him. “The camera goes in first. Everything else follows from what it shows.”

Alpharetta’s housing stock makes Air Duct Cleaning services with Lennox-specific expertise especially relevant. The 1990s-2000s subdivision homes dominating Windward and similar communities - 3,000 to 5,000+ square feet, two or three flex-duct zones, equipment now 20 to 30 years old - represent a density of aging multi-system homes no neighboring city matches. Those attic-mounted air handlers and furnaces run through Georgia humidity cycles and some of the Southeast’s heaviest pollen loads. The equipment brand matters because Lennox cabinet designs, coil configurations, and blower behaviors create specific failure patterns in these conditions.

Why Trust CleanRun Air Duct Cleaning Alpharetta for Your Lennox Air Duct Cleaning?

We have worked on enough Lennox service in Roswell and Alpharetta systems to know the difference between an equipment problem and a duct problem - and how often they overlap. The high-static ECM blowers in Dave Lennox Signature Collection units (SL280V, SLP98V, EL296V) and Elite Series models rarely throw a fault code until airflow has dropped severely. Homeowners call us thinking the furnace is failing when the real issue is a loaded return duct, a compressed flex run, or a blower wheel choked with debris. We check static pressure across the coil and at the plenum before recommending any scope of work.

Our technicians operate under Haven Standard Clause 3: Verified Crews - background-checked, uniformed, identified by name before arrival. We carry OEM Lennox gaskets, door seals, and cabinet hardware for fitment-critical repairs, plus professional-grade equipment from Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman for the cleaning and distribution work. Every job starts with a written price under Haven Standard Clause 1. No exceptions. No “call for a quote.”

Tomas Reyes runs a tighter schedule than most contractors you will meet - weekends are for youth soccer coaching - which means your appointment time is your appointment time. The photo record we deliver shows particulate buildup measurements, debris composition, and duct integrity notes before any scope discussion. You see what we see.

Common Lennox Air Duct Cleaning Problems We Fix in Alpharetta

• ECM blower wheel loading on Signature and Elite units. The variable-speed blowers in Lennox SL280V, SLP98V, and EL296V furnaces move high static pressure by design, but that same capacity pulls fine debris deep into the wheel vanes. In Alpharetta, where spring pollen counts spike and attic dust infiltrates return systems, we regularly find blower wheels caked with a paste of pollen, drywall dust, and lint. The motor does not fault until airflow drops enough to trip a pressure switch. We remove the blower assembly, clean the wheel and housing, and measure static pressure before and after.
• Biofilm buildup on evaporator coils in horizontal air handlers. Lennox horizontal air handlers use a sloped drain pan design that can trap condensate and dust near the coil face. Combined with Alpharetta’s extended cooling season - systems running hard from April through October - this creates ideal conditions for biofilm growth that mats across the coil fins and restricts airflow. Our evaporator coil cleaning service addresses this directly, with before-and-after photos of the coil face.
• Return-side air leaks through cabinet seams and door gaskets. Lennox metal cabinet seams and door gaskets degrade over time, especially on older Merit Series installs (ML180, ML193). In Alpharetta’s hot attic environments, thermal cycling accelerates gasket compression set. The system pulls attic air - 140°F in July - directly into the return, raising humidity load and introducing fiberglass and particulate. We replace OEM gaskets and seal seams with mastic rated for the temperature range.
• Flex duct sagging and compression at supply plenums. The flex duct transitions at Lennox supply plenums are prone to sagging in Alpharetta’s long attic runs, particularly on the second-floor zones common in Windward and similar subdivisions. A compressed flex elbow can drop delivered CFM by 30% or more. Homeowners blame the equipment. We photograph the restriction, replace or support the flex run, and verify airflow at the register.
• Duct board plenum liner degradation in 1990s-2000s installs. Technicians working Alpharetta’s 1990s subdivisions routinely find original duct board plenums shedding fiberglass liner inward. This is not a Lennox-specific issue, but it affects Lennox systems disproportionately because the same housing cohort runs so much equipment in hot, humid attics. The particulates move straight into conditioned air. We document this with camera footage and recommend plenum replacement when liner integrity is compromised.

Lennox Parts & Our Repair-vs-Replace Approach

We use OEM Lennox gaskets, door seals, and cabinet hardware when fitment tolerances matter - a door seal that does not seat correctly creates a return leak that undermines everything else. For distribution-side work, quality aftermarket flex duct, mastic, and insulation perform equally well and allow us to keep turnaround times short without sacrificing durability.

If a Lennox coil or heat exchanger is corroded or cracked, we tell you honestly. Repair only makes sense when the cabinet and blower are sound enough to justify the investment. We have replaced evaporator coils on EL296V units where the cabinet was pristine, and we have recommended full air handler replacement on ML180 systems where corrosion had compromised multiple components. The decision comes with a written explanation and photos, not a sales pitch.

Our Lennox Service Process - Step by Step

1. 1
   Diagnosis with static pressure and visual inspection. We measure external static pressure across the Lennox coil and blower, inspect the evaporator coil face through the cabinet access, and run a camera through the return and supply ductwork. The photo record starts here.
2. 2
   Written scope and price. Before any panel comes off, you receive a written price under Haven Standard Clause 1. The scope specifies what we found, what we recommend, and what the photo record will cover.
3. 3
   Cleaning and repair execution. We clean the evaporator coil, blower wheel and housing, and duct runs using negative-pressure extraction. Duct sealing with mastic or tape as appropriate. OEM parts where specified. All work photographed.
4. 4
   Testing and verification. We re-measure static pressure, verify temperature drop across the coil, and check airflow at problem registers. The after photos are added to your job record.
5. 5
   Documentation and warranty. You receive the complete photo record, the written scope, and the 365-Day Done Right Promise in writing. If it is not right, we make it right.

FAQs - Lennox Air Duct Cleaning Service in Alpharetta

Is CleanRun Air Duct Cleaning Alpharetta authorized by Lennox?

No. We are an independent service provider, not affiliated with or authorized by Lennox. That independence allows us to diagnose based on what we find in your ductwork and cabinet, not based on manufacturer protocols that may miss distribution-side problems.

Do you use genuine Lennox/OEM parts?

We use OEM Lennox gaskets, door seals, and cabinet hardware where fitment is critical. For distribution-side repairs - flex duct, mastic, insulation - quality aftermarket parts perform equally well and are what we typically install. We specify which type we are using in your written scope.

How long does Lennox service take?

Most residential cleanings and minor repairs take three to five hours. A full evaporator coil cleaning, blower service, and duct sealing on a multi-zone system in a large Alpharetta home may extend to a full day. We give you a time estimate in writing with the price.

What Lennox models/series do you cover?

We service Dave Lennox Signature Collection (SL280V, SLP98V, EL296V), Elite Series (EL180, EL280, ELO183), Merit Series (ML180, ML193, ML296V), and iComfort-enabled communicating systems. If your model is not listed, call (678) 679-7540 and we will confirm coverage.

Will service void my Lennox warranty?

Proper duct cleaning and sealing does not void equipment warranties. We document our work with photos and written scope, and we use OEM cabinet parts where required. If your system is still under manufacturer warranty, we note this in our pre-work inspection and adjust parts selection accordingly.

How much does Lennox air duct cleaning cost in Alpharetta?

Whole-system duct cleaning for a typical Alpharetta home runs $450-$850 depending on system count and accessibility. Evaporator coil cleaning adds $180-$340.
