Independent Air Duct Cleaning - Lewisville for Lennox systems typically runs $280-$520 for a complete system, with flex duct repair or coil cleaning added separately. What separates our work here is the combination: we know Lennox blower and coil configurations from the Merit through Signature lines, and we know how Lewisville’s lake humidity and 1980s tract-home flex duct interact to create problems neither factor causes alone.

Why Lewisville Residents Choose Us for Lennox Service

We’ve worked on Lennox systems across Denton County for years, and our techs know the exact coil, blower, and flex-duct configurations used in the tract builds that dominate Lewisville. Because we’re independent, we answer only to the homeowner - not to a manufacturer’s warranty script.

Tomas Reyes grew up in Queens, NY, picked up his HVAC fundamentals at Manhattan’s Apex Technical School, and has spent the next two-plus decades working inside ductwork across North Texas. He and our crew have been running jobs in Lewisville for years - including plenty of Lewisville Dryer Vent Cleaning and older homes near Castle Hills, where the flex duct tends to sag and accumulate debris in ways that don’t show up until you put a camera inside. Tomas built CleanRun around one habit: photographing what’s in the duct before and after, so the homeowner can see exactly what changed and for how much.

Our Lennox sales & service approach means we stock OEM-equivalent aftermarket flex duct, mastic, and coil cleaners that meet or exceed Lennox specs - no dealer markup on consumables for out-of-warranty systems. Every job carries a written price before work begins, a Documented Photo Record of every duct run, and the 365-Day Done Right Promise backed in writing. Lewisville service area coverage means we’re not driving from Plano or Fort Worth to get to your attic.

Common Lennox Air Duct Cleaning Problems We Solve in Lewisville

• Flex duct liner collapse in 140-150°F Lewisville attics. North Texas attic temperatures degrade flex duct inner liners and vapor barriers faster than temperate climates. On 1980s-1990s Lennox systems with original builder-grade flex runs, the inner vapor barrier wrinkles and sheds fiberglass into supply air. We replace compromised sections with new flex rated for local attic conditions.
• Return plenum and boot connection gaps from Blackland Prairie clay slab movement. Lewisville’s expansive clay soils shift continuously, stressing duct boot connections and plenum seams. On Lennox air handlers, these gaps pull attic insulation fibers, rodent dander, and construction dust straight into the blower and evaporator coil. We mastic-seal every gap and photograph the repair.
• Evaporator coil fouling from lake-driven humidity. In near-shore subdivisions, Lennox cased coils in CBX27UH air handlers stay damp longer between AC cycles. That moisture feeds microbial growth on the coil face and downstream duct interiors - a pattern we see measurably worse than in comparable homes a few miles south in Carrollton.
• Blower wheel imbalance from debris ingestion. When flex duct seals fail in high-clay-movement zones, attic particulate cakes onto the Lennox blower wheel. The resulting vibration and reduced airflow owners often mistake for a failing motor. We clean and rebalance, or recommend replacement if corrosion has set in.
• Black mold colonization in east-shore flex duct. In late-1980s subdivisions built on former Corps of Engineers buffer land along Lake Lewisville’s eastern shoreline, our techs routinely pull Lennox flex duct sections with visible black mold on the inner liner - a severity we almost never see on same-vintage Lennox systems just a few miles west of I-35E, where lake humidity doesn’t reach.

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

Lewisville’s explosive suburban growth along I-35E in the 1980s and early 1990s left the city with a dense inventory of tract homes whose original builder-grade flexible ductwork is now 30-40 years old - well past the 15-25 year functional lifespan of flex duct. The city’s direct adjacency to Lake Lewisville elevates ambient humidity in lakeside neighborhoods far more than in landlocked neighbors like Carrollton or Farmers Branch, accelerating mold and microbial colonization inside those already-aging duct systems in ways that are genuinely distinctive to this part of Denton County.

For Lennox owners, this means two forces working together. The Merit Series ML14XC1 or ML13KC that came with your 1994 tract home was paired with flex duct installed to minimal standards of the era. That duct’s inner liner is now brittle from a decade and a half of 140°F+ attic summers. Add lake-driven humidity that keeps the duct interior damp after the AC cycles off, and you’ve got conditions that degrade the vapor barrier while feeding mold - a combination that shows up on our cameras as wrinkled liner, moisture-matted fiberglass, and black microbial staining. The same vintage Lennox system on the dry west side of I-35E rarely shows the same severity. Here’s the before photo. Now let’s talk about what happens next.

Lennox Models & Products We Service in Lewisville

We service the full range of residential Lennox equipment found in Lewisville homes:

• Lennox Merit Series (ML14XC1, ML13KC) - common builder-grade units in 1990s Lewisville tract homes; often paired with original flex duct now past functional lifespan
• Lennox Elite Series (EL16XC1, EL18XCV) - seen in mid-2000s two-story brick homes near the lake; higher-efficiency coils require careful cleaning to protect fin density
• Lennox Dave Lennox Signature Collection (SL28XCV, SL280V) - higher-end replacements in established Lewisville neighborhoods; precision blower assemblies demand documented balancing after any duct repair
• Lennox CBX27UH and CBA27UHE air handlers - paired with many of the above in attic installations; cased coils vulnerable to the humidity-mold cycle specific to east-shore Lewisville properties

We use OEM-equivalent aftermarket flex duct, mastic, and coil cleaners that meet or exceed Lennox specifications. No need to pay dealer markup for consumables on an out-of-warranty system. When a Lennox coil or blower is genuinely failing, we tell you straight: repair if the cabinet and refrigerant circuit are sound, replace if corrosion or compressor age makes further investment unwise.
