We’ve spent years inside Lennox systems across Cumming, from Merit Series furnaces in the original Windermere builds to Signature Collection variable-speed heat pumps in newer lakeside subdivisions, and we also handle Lennox service in Buford. The camera doesn’t have an opinion - it just shows you what’s in there. That documented approach matters especially with Lennox equipment, where variable-speed ECM motors and communicating controls will mask airflow problems until efficiency has already dropped substantially.

Cumming’s housing stock creates a specific challenge for Lennox owners. Most homes here went up between 2000 and 2015 with builder-grade flex duct and multi-zone layouts. The red Georgia clay dust and drywall particulate from construction often sat undisturbed in plenums for years. Now those systems are 10-20 years old, and the combination of accumulated debris, sagging flex, and humid attic conditions has started showing up as blower wheel fouling, coil biofilm, and collapsed return branches - problems we photograph before touching a single fitting.

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

Tomas Reyes, our owner, grew up in the Bronx and picked up his HVAC fundamentals at Bronx Community College before spending the better part of two decades working through every configuration of residential ductwork imaginable. He and our crew have run Lennox jobs across Cumming for years, including plenty of calls in the Vickery subdivision where two-story layouts hide surprising debris loads in return-air trunk lines. Tomas documents conditions with a camera before touching a single fitting - customers get a before-and-after record, not a verbal summary.

We know Lennox equipment specifically. The Merit Series ML180E with its fixed-speed blower behaves differently under duct restriction than the Elite EL296V with its variable-speed ECM. The Signature SLP98V’s communicating iComfort controls monitor static pressure and will ramp the motor to compensate for collapsed flex - which sounds like sophisticated engineering until you realize it’s slowly overworking itself to push air through a torn return in a Cumming attic. We catch that because we measure static before and after, not just vacuum out what we can reach.

Our parts approach is straightforward. We use Lennox OEM-equivalent filter media and replacement collars where fit and airflow specification matter, and quality aftermarket flex, mastic, and hard-cast fittings for duct repairs. Haven Standard Clause 1 requires a written price before any work starts - every time, no exceptions. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise is backed in writing on every job.

Common Lennox Air Duct Cleaning Problems We Fix in Cumming

• Filter-drier and cabinet-return air leaks on Merit Series units. Builder-grade installation in Cumming’s 2000s subdivisions often left panned returns or loose flex collars on ML and EL series furnaces. These gaps pull attic dust and insulation fibers directly into the blower compartment, bypassing the filter entirely. The debris then pushes through branch runs and registers. We find this constantly in original Windermere and SR-400 corridor homes where the furnace sits in a vented attic or garage closet. Our fix: seal the return plenum with hard-cast mastic, replace deteriorated flex collars, and clean the blower housing.
• Caked secondary heat exchanger and blower wheel in Elite/Signature variable-speed furnaces. The constant low-speed airflow of EL296V and SLP98V units operates at lower static pressure than fixed-speed systems. Fine drywall dust - especially prevalent in Cumming homes where post-construction cleaning never happened - migrates past standard filters and polymerizes onto the blower wheel and secondary coil fins. The furnace keeps running, but capacity drops and the heat exchanger runs hotter. We remove and clean the blower assembly, then video-inspect the secondary cell.
• Premature return-duct collapse and inner-liner dust in Signature Series communicating systems. The XC25 heat pump and SLP98V furnace use ECM motors that ramp to maintain programmed airflow targets. When cheap builder-grade flex deteriorates, the motor simply works harder, collapsing the duct further and shedding fiberglass liner material that plugs the evaporator coil. We’ve replaced entire return trunks in Bethelview Road homes where the communicating system had been compensating for months before the homeowner noticed uneven temperatures.
• Evaporator coil fouling on matched Lennox indoor coils in attic or garage air-handler closets. Cumming’s humid subtropical climate means HVAC systems run April through October, and Lake Lanier’s evaporative effect keeps duct lining surfaces damp in lakeside subdivisions. Any air-sealing gap allows unconditioned attic air to infiltrate, and the combination of humidity plus debris creates biofilm on the coil. A fouled coil on a Lennox CBA38MV air handler drops capacity and raises supply temperatures - we clean the coil with foaming cleaner and negative-pressure extraction, then seal the cabinet.
• Construction debris compaction in original plenums. In Cumming’s rapid-build 2000s subdivisions, framing and HVAC crews worked simultaneously. We routinely pull registers in 15-year-old homes and find red Georgia clay dust and drywall particulate still compacted at the bottom of the plenum, untouched since move-in day. Lennox systems with high-static blowers - especially the Elite and Signature series - eventually re-entrain this material. Our Rotobrush and Nikro equipment agitates and extracts it, with before-and-after photos of every run.

Lennox Parts & Our Repair-vs-Replace Approach

We stock Lennox OEM-equivalent filter media, replacement collars, and cabinet gaskets locally for fast turnaround on Cumming jobs. For duct repairs, we use quality aftermarket flex rated to UL 181 Class 1, hard-cast mastic for plenum sealing, and Abatement Technologies HEPA filtration during cleaning. The distinction matters: OEM parts where precise airflow and fit are critical, aftermarket where the specification is standard and the savings are real.

If we open your Lennox system and find a corroded heat exchanger or cracked coil, we’ll tell you directly. Duct cleaning alone won’t fix it. Haven Standard Clause 1 means you get that assessment in writing, with a scope and price, before any work proceeds. No bait-and-switch. No $79 coupon that becomes a $900 invoice once the van is in your driveway. Call (678) 693-5322 and we’ll put our number next to any competitor’s written estimate - free second opinion, no obligation.

Our Lennox Service Process - Step by Step

1. 1
   Diagnosis with documentation. We start with static pressure measurement at the furnace and key registers, then run a video inspection through the duct system. For Lennox variable-speed systems, we also pull blower RPM and torque data from the control board where accessible. You get photos of what we found before we propose any work.
2. 2
   Written scope and price. Haven Standard Clause 1: every repair, cleaning, and replacement item is listed with a fixed price. No per-vent pricing. No open-ended hourly rates. One flat price per system, agreed in writing before a panel comes off.
3. 3
   Service execution. Full system cleaning includes negative-pressure extraction with Rotobrush agitation, evaporator coil cleaning with foaming cleaner and rinse, and blower wheel removal and cleaning. We use Honeywell and Aprilaire media replacements where specified, Guardsman sealants for plenum repairs, and Nikro HEPA vacuum collection.
4. 4
   Post-service testing and photo record. Static pressure is measured again and compared to the pre-service reading. The Documented Photo Record - before and after images of every duct run, the coil, and the blower - is delivered as part of your standard job record. The 365-Day Done Right Promise is activated in writing.

FAQs - Lennox Air Duct Cleaning Service in Cumming

Is CleanRun Air Duct Cleaning Cumming authorized by Lennox?

No. We are an independent Lennox service provider with no manufacturer affiliation or authorization. This is stated clearly on every proposal. Our incentive is to restore your system’s airflow as designed, not to sell new equipment. Being independent means we can recommend repair over replacement when that’s the honest call.

Do you use genuine Lennox/OEM parts?

We use Lennox OEM-equivalent filter media and replacement collars where precise fit and airflow specification matter, and quality aftermarket components - UL 181 Class 1 flex, hard-cast mastic, professional-grade sealants - for duct repairs where the specification is standard. We name the manufacturer on every part in our written scope.

How long does Lennox service take?

A typical full system cleaning on a Lennox furnace and coil in a 2,500-3,500 square foot Cumming home takes 3-5 hours, depending on debris load and accessibility. Variable-speed Elite and Signature systems add time for blower removal and careful reassembly. We do not rush the documentation - every run gets photographed. Call (678) 693-5322 to schedule; we’ll give you a time window in writing.

What Lennox models/series do you cover?

All current and recent-discontinuation residential lines: Merit Series (ML/EL furnaces, 13ACX/14ACX ACs), Elite Series (EL296V, EL18XPV), Signature Collection (SLP98V, XC25, XP25), and matched indoor coils (CBA38MV, CX34). We also service Dave Lennox Signature Collection high-efficiency heat pumps. If you have a model number, text it to (678) 693-5322 and we’ll confirm parts availability before scheduling.

Will cleaning my Lennox ductwork void the equipment warranty?

No. Warranty coverage is not affected by duct cleaning performed by a qualified technician. Where we open the cabinet to clean the blower or coil, we use manufacturer-specified reassembly torque and gasket replacement. We document our work with photos in case any warranty question arises. If your system is still under Lennox factory warranty, we’ll note that in our written scope and flag any conditions that should be handled through your installing dealer.

How much does Lennox air duct cleaning cost in Cumming?

Whole-system Lennox air duct cleaning in Cumming typically runs $450-$750 for homes between 2,500 and 4,000 square feet, depending on system accessibility, debris load, and whether evaporator coil or blower cleaning is included. Duct repair, flex replacement, or plenum sealing are priced separately in the same written scope. We do not quote per-vent or offer teaser rates. One flat price per system, agreed before work starts. Call (678) 693-5322 for a written estimate - estimates are free, and we’ll match our number against any competitor’s written quote.
