Lennox Air Duct Cleaning in Mansfield, TX | Hollis Air Duct Fort Worth
We provide independent Lennox Air Duct Cleaning - Mansfield, and the quick answer is this: a full-system cleaning on a Lennox home here typically runs $450 – $850 depending on duct count, with flex-duct repair and evaporator coil cleaning quoted separately before any work begins. What makes our Lennox work different in Mansfield is that we know these systems age faster here because of U.S. 287 construction silt and attic heat degrading flex duct. Roy Castellanos, our owner, has worked on Lennox equipment in Mansfield since the early 2000s and built our process around what actually fails on these units in North Texas. Call (682) 255-2572 for a written estimate.
Why Mansfield Residents Choose Us for Lennox Service
Lennox systems are specific machines. A Merit Series furnace moves air differently than an Elite or a Dave Lennox Signature unit, and the duct connections, coil designs, and blower settings all change how dust accumulates. We’re an independent contractor, not a Lennox dealership or factory-authorized service provider, which means we answer to you and the condition of your ductwork, not a manufacturer’s parts quota. Roy learned HVAC fundamentals at Los Angeles Trade-Technical College and has spent the better part of two decades cleaning and inspecting Lennox systems across Fort Worth and Mansfield. He knows what a sagging flex-duct plenum looks like on an ML180 in a hot Mansfield attic, and he trains our technicians to catch it before it becomes a dust problem in your living room.
We serve the whole Mansfield service area, from older 1990s tract homes near Walnut Creek to new construction off Broad Street. Our techs arrive uniformed and background-checked. The price is written before we touch anything. And every job carries our 365-Day Done Right Promise in writing. If something fails within a year, we return at no charge. That’s the Garrison Standard, and it applies to every Lennox duct cleaning we do in Mansfield.

Common Lennox Air Duct Cleaning Problems We Solve in Mansfield
- iComfort thermostat calibration drift after attic heat exposure. Mansfield attics hit 130°F or more in summer. That heat causes Lennox iComfort S30 and older iComfort Wi-Fi thermostats to lose calibration, so the blower runs more often than it should. Extra blower runtime pulls more pollen and dust through the return side. We check thermostat settings and blower-on schedules during every cleaning.
- Flex-duct plenum gaps on Merit and Elite furnace installations. Hot Mansfield attics soften the mastic and tape connections at the plenum. When those gaps open, the return side ingests blown-in fiberglass insulation and fine construction dust. We find this on ML180 and EL296V installs regularly, and we seal gaps with fiber-reinforced mastic before cleaning so the problem doesn’t return in six months.
- Evaporator coil growth on older 14 SEER Lennox units. Mansfield’s humid shoulder seasons, spring and fall, create condensation on evaporator coils that sits long enough for biological growth to take hold. The ADP/Allied-style slab coils on many 14 SEER Lennox condensers are especially prone to it. That growth sheds spores into supply ducts. We clean coils with coil-safe chemistry and document the before-and-after.
- Undersized return-air cans on two-story Lennox Elite setups. Builders in Mansfield’s 2000s-era subdivisions often installed return-air cans too small for the Lennox Elite systems they paired them with. High duct static forces dust out of supply registers even in a clean home. We measure static pressure during inspection and tell you honestly if a return-air upgrade is the real fix.
- Blown-in fiberglass contamination from hot attic flex duct degradation. Texas heat breaks down the inner liner of flexible ductwork over time. When that liner fails, fiberglass particles ride the airstream straight into your supply registers. This is more common in Mansfield than in cooler climates, and it’s why we use negative-air machines and HEPA filtration on every job, not just a spinning brush.
Lennox Service in Mansfield: What Local Conditions Mean for Your Equipment
The 76063 ZIP code is bisected by U.S. 287, and that corridor has been under near-constant commercial redevelopment for years. Homes within a mile of the highway see more fine brown construction silt in their return ducts than identical Lennox floor plans in Arlington or Grand Prairie. That silt is finer than household dust, it packs tighter in duct liners, and it resists light brushing. We use Nikro negative-air machines with HEPA filtration to pull it out, and we inspect return-air cans in 287-adjacent Mansfield homes more carefully because the silt concentration there is measurably higher. If you live in neighborhoods like Walnut Creek Hollow or anywhere east of 287 toward Joe Pool Lake, your Lennox system is working harder against a heavier particulate load than the same model would in a quieter suburb. That’s not marketing. It’s what our video inspections show.
Lennox Models & Products We Service in Mansfield
We work on the full Lennox line across Lennox sales & service territory in Mansfield: Merit Series ML180 and ML193 gas furnaces, Elite Series EL296V and EL195 furnaces plus EL18XCV air conditioners, and the Dave Lennox Signature Collection including SL280V, XC25, and SLP98V. We also service Healthy Climate HC16 and HC13 media cabinets and iComfort S30 thermostats. For parts, we stock factory-size Lennox-compatible O-rings, media filters, and coil-safe cleaning kits locally for same-day Mansfield turnaround. When a flex-duct repair has to happen in a hot attic that afternoon, we use name-brand aftermarket flex duct and mastic. For iComfort controls or variable-speed motor issues, we recommend OEM Lennox parts every time. We’ll tell you plainly when a coil or heat exchanger has seen enough years of Mansfield hard water and pollen that replacement is smarter than another repair.

FAQs – Lennox Air Duct Cleaning in Mansfield
Because the filter is only the first line, not the last. On Elite systems in Mansfield, the return-side ductwork is usually the dust reservoir. A new filter actually increases airflow and can pull more accumulated dust off the duct walls and through the supply registers. The fix is cleaning the ducts and the evaporator coil, not changing the filter more often. Call (682) 255-2572 and we’ll show you what’s inside your return duct on video.
Every three to five years for most Mansfield homes, but closer to three if you’re within a mile of U.S. 287 construction or you have pets, high pollen sensitivity, or a home built before 2005 with original flex duct. Mansfield’s hot, humid summers mean your Lennox blower runs nearly year-round, so there’s no real off-season where dust settles out of the airstream. We’ll give you a straight answer for your house after one inspection.
It can be. The iComfort tracks blower runtime, not actual filter condition, but a system that trips the reminder frequently is moving a lot of air, and in Mansfield that air carries pollen, construction silt, and attic dust. If you replace the filter and the reminder returns within a month, your return duct is likely loading the filter faster than it should. That’s worth a video inspection to see what’s actually in the ductwork before it hits the coil.
Yes, if the dust is dark, sticky, or accompanied by a musty smell when the AC runs. That’s coil shedding, common on 14 SEER Lennox slab coils in Mansfield’s humid spring and fall. Cleaning the coil removes the source. Cleaning the ducts removes the accumulated fallout. We do both, and we’ll show you the coil before and after so you’re not taking our word for it.
It is when your flex duct runs through a hot attic. Mansfield summers push attic temperatures past 130°F, and that heat degrades the inner liner of flexible duct faster than it does in cooler climates or slab-on-grade homes. Once the liner fails, fiberglass particles enter the airstream. We see it on Lennox Merit and Elite installs in Mansfield’s 1990s and 2000s subdivisions more often than in newer construction nearby. If you’re seeing fine fibers on furniture near supply registers, call (682) 255-2572 and we’ll inspect the duct runs with our Dryer Vent Cleaning in Mansfield before you spend money on cleaning that won’t fix a liner failure.
