Lennox Air Duct Cleaning in Duluth, GA

Lennox Air Duct Cleaning in Duluth, GA | CleanRun Air Duct Cleaning Johns Creek

We provide independent Lennox service across Duluth, not as an authorized dealer but as technicians who have worked on Dave Lennox Signature, Elite, and Merit systems in this specific market since 2013. The one thing that makes our Lennox work here different is this: Duluth’s late-1980s through late-1990s flex duct stock, routed through super-heated attics, fails at the plenum boot in ways that show up as “equipment problems” but are actually duct problems. We find it, photograph it, and quote it in writing before touching a tool. Call (470) 326-1926 for a free estimate.

Why Duluth Residents Choose Us for Lennox Service

Our crew has worked on Lennox equipment in Duluth long enough to know the difference between an EL296V with a failing blower motor and one with a blower wheel choked with degraded fiberglass from a collapsing supply run. We’ve serviced homes from the Riverbrooke subdivisions to the Pleasant Hill Road corridor, and we’ve learned that Duluth service area homes built during Gwinnett County’s boom years share a common architecture: Lennox air handlers sitting in unconditioned attics, mated to flex duct that has now seen three decades of thermal cycling.

Tomas Reyes, our owner, grew up in Queens helping his uncle patch window units in apartment buildings. He trained at CUNY Kingsborough Community College before spending two decades on duct work across the Southeast. For the past several years, he and his crew have worked the Medlock Bridge corridor and throughout Duluth. The photo goes first. The price comes after. That’s how we operate, and it’s why we deliver a Documented Photo Record on every visit, included as standard, not as an upsell.

We are not affiliated with, authorized by, or endorsed by Lennox. We are an independent service company. We use OEM Lennox parts for cabinet-specific components like plenum flanges and blower motor mounts, and quality aftermarket materials when the original parts are discontinued or when code-compliant upgrades outperform them. Every job starts with a written price under Haven Standard Clause 1, and every job ends with before-and-after photos of every duct run.

Common Lennox Air Duct Cleaning Problems We Solve in Duluth

• Sagging and disconnection at the plenum boot transition. Duluth’s 130°F+ attics cause repeated thermal expansion and contraction at the joint where Lennox air handler plenum boots meet 1990s-era flex duct collars. The result is conditioned air pumping directly into the attic. We re-secure with mastic and mechanical fasteners, then photograph the repair.
• Fiberglass liner delamination and mold on cold supply duct interiors. A Lennox evaporator coil runs at roughly 45°F. In a Duluth attic hitting 130°F, that thermal differential drives condensation through small liner tears. Mold colonizes the interior surface, visible only on video inspection. We clean with negative-pressure extraction and document the interior condition.
• Dirty evaporator coils from years of unfiltered return air. Lennox air handlers with 1-inch filter slots are frequently found with system bypass around the filter, allowing dust and biological growth to coat the coil. This drops capacity and raises head pressure on the compressor. Our evaporator coil cleaning service addresses this directly.
• Blower wheel imbalance from fibrous liner debris. As interior duct liner breaks down, fiberglass particles pull through the return and accumulate on the Lennox blower wheel. The vibration and reduced airflow are often misdiagnosed as motor failure. We remove the wheel, clean it, and photograph the debris load.
• Static pressure overload from collapsed flex duct sections. Original flex duct in Duluth’s 1987-2002 builds has sagged between trusses, creating kinks that push the Lennox blower past its design static pressure. The system runs longer, wears faster, and delivers less air. Our duct repair and sealing service restores proper airflow paths.

Lennox Service in Duluth: What Local Conditions Mean for Your Equipment

The original flex duct in Duluth’s late-1980s through late-1990s subdivisions along Pleasant Hill Road and Peachtree Industrial Boulevard is now at or past its 20-25-year service life. Gwinnett County’s humid summers and unconditioned attic plenums mean these specific runs show liner breakdown and mold at rates we don’t see in newer-build suburbs like Suwanee. The result is that a routine Lennox sales & service call in Duluth frequently uncovers disconnected plenum boots and interior duct contamination that would not be found in a home with more recent ductwork.

On a 1994 two-story off Pleasant Hill Road near the Duluth Highway intersection, a homeowner with a 2011 Lennox Elite EL296V furnace called us because the upstairs bedrooms wouldn’t cool below 78°F on a July afternoon. Our tech found the original flex supply trunk sagging in the attic, with the collar at the Lennox plenum boot partially disconnected. We re-secured and mastic-sealed the connection, cleaned the interior mold from two supply runs, and pulled a wad of degraded fiberglass liner off the blower wheel. The upstairs dropped 6°F and the compressor no longer ran continuously. The before photographs showed the disconnection; the after photographs showed the sealed joint and clean duct interior. That’s the Documented Photo Record we deliver on every job.

Lennox Models & Products We Service in Duluth

We work on the full range of residential Lennox equipment found in Duluth homes. The Dave Lennox Signature Collection includes variable-capacity furnaces like the SL280V, SLP98V, and EL296V. The Lennox Elite Series covers the EL296E, EL180E, and XC20 air conditioners. The Lennox Merit Series includes the ML180, ML193, and 14ACX equipment. We also service Lennox Healthy Climate indoor air quality accessories: MERV filters, HRV/ERV units, and bypass humidifiers.

For cabinet-specific repairs, we stock OEM Lennox plenum flanges, drain pans, and blower motor mounts. For flex duct, mastic, and insulation replacement, we use quality aftermarket materials from Abatement Technologies, Honeywell, Aprilaire, and Guardsman. Our equipment roster includes Rotobrush, Nikro, and Abatement Technologies cleaning systems for Duluth Dryer Vent Cleaning and full duct service. You can verify these brands independently. If your Lennox furnace or air handler is under 12 years old and the heat exchanger or coil is sound, duct repair and resealing is almost always the right call. We replace equipment only when the heat exchanger is cracked or the repair estimate exceeds 40% of a new system.

FAQs - Lennox Air Duct Cleaning in Duluth

Does cleaning my Lennox air handler’s blower and coil really make a difference here in Duluth?

Yes. Duluth’s humid climate means evaporator coils operate under heavier biological load than drier markets, and blower wheels accumulate fiberglass debris from aging flex duct at rates that reduce airflow by 15-25% in the homes we measure. Cleaning both restores capacity and reduces compressor run time. Call (470) 326-1926 for an exact quote - estimates are free.

My house was built in 1996 off Peachtree Industrial Boulevard - is the original flex duct still okay to clean?

Sometimes, but not always. Flex duct has a 20-25-year service life, so 1996 duct is at or past replacement age. We video-inspect first. If the liner is intact and the plenum connections are secure, cleaning is appropriate. If we find liner delamination or disconnection, we quote repair or replacement in writing before proceeding. Call (470) 326-1926 for an exact quote - estimates are free.

What’s the connection between Lennox equipment and duct sizing in these older Duluth homes?

Many Duluth homes were built with flex duct sized for the original equipment load, then upgraded to higher-capacity Lennox systems without duct modification. The result is static pressure that exceeds the blower’s design limit, accelerating wear. We measure static pressure during every service and flag mismatches. Call (470) 326-1926 for an exact quote - estimates are free.

Will you use Lennox-branded parts if my plenum boot or flex collar needs replacement?

For cabinet-specific components like plenum flanges and blower motor mounts, yes - OEM Lennox parts. For flex duct, collars, and insulation, we use quality aftermarket materials that meet or exceed original specifications, often outperforming discontinued Lennox parts. We specify what’s being used in your written scope. Call (470) 326-1926 for an exact quote - estimates are free.

How do you check for mold inside the ductwork when the outside of the duct looks fine?

We run a video inspection camera through every duct run, recording the interior surface condition. The exterior of flex duct in a Duluth attic tells you almost nothing about the interior - condensation-driven mold grows on the cold side, hidden from view. You receive the video and still photographs as part of the Documented Photo Record. Call (470) 326-1926 for an exact quote - estimates are free.
